Using PSA to determine prognosis

The 186,000 or so men likely to be diagnosed with prostate cancer in the United States this year will face a myriad of choices and ask countless questions. “Am I going to die of this disease?” is likely the most frequent query. Until relatively recently, this question was nearly impossible to answer. After all, it wasn’t until the late 1980s that testing for prostate-specific antigen (PSA) began; before that, most prostate tumors were detected during a digital rectal examination (DRE), when they were advanced enough to be felt through the rectal wall.

The advent of PSA screening meant that prostate cancer could be detected at an early stage, perhaps more than a decade before it would cause symptoms. But then what? What did a particular PSA test result mean for an individual patient? Did the same numerical PSA score in two different men mean the same thing? Was there any significance to a PSA level that rose quickly instead of gradually? Could doctors use PSA to determine which patients would be the best candidates for surgery? For radiation? For a clinical trial? Was there any way to know who might be cured and who was likely to die of the disease?

These are just a few of the many questions that spurred Dr. Anthony D’Amico to study PSA, its rate of change, and its role in a patient’s prognosis. He also wanted to know whether the prognosis would change if he opted for a different treatment method. After studying how more than 1,800 men fared years after treatment, he and his research team released their findings in a 1998 landmark study in The Journal of the American Medical Association.

The team stratified patients into risk groups depending on three factors — one of which was PSA. The findings that defined the risk groups became known in medical circles as the “D’Amico criteria.” And although more than a decade has elapsed since the study was published, doctors continue to rely on these criteria to help patients make treatment decisions.

We talked with D’Amico, chief of genitourinary radiation oncology at Brigham and Women’s Hospital and Dana-Farber Cancer Institute in Boston. He is also a professor at Harvard Medical School and the principal investigator of several federally funded studies. A prolific researcher, D’Amico has written more than 150 peer-reviewed original publications and editorials for medical and scientific journals. Here he shares what inspired his PSA research, how it’s relevant in the clinic, and his own recommendations for patients.

Change in PSA based on risk group and treatment choice

These two graphs show how low-risk and high-risk patients in D’Amico’s 1998 landmark study fared — in terms of biochemical recurrence — over time with four different treatments: radical prostatectomy, external beam radiation therapy, seed implants combined with hormone therapy, and seed implants alone. The four rows of numbers at the bottom of each graph represent the number of patients in each group at the corresponding time point in years (top row, radical prostatectomy; second row, external beam radiation therapy; third row, seed implants and hormone therapy; and last row, seed implants alone). Interestingly, for low-risk patients, the type of treatment made little difference when it came to experiencing biochemical recurrence.

Early PSA research

What inspired your research on PSA and how quickly it changes?

My patients inspired me. A gentleman came in with a PSA of about 4 ng/ml, and he asked me, “Do you think it matters that my PSA was 1 ng/ml last year?” The man I had seen just before him had a PSA of about 4, too, but his PSA the year before had been 3.2 ng/ml. That piqued my curiosity. His question was what inspired me to look at the rate of change in PSA before treatment as a potential prognostic factor.

Patients also inspired me and my colleagues to look at PSA levels after surgery. With some patients, the PSA would be 0.1 after surgery, then 0.5, and then, all of a sudden, 3 ng/ml, and their bone scans would turn positive and their CT scans would light up. But then there were patients whose PSAs would go from 0.1 after surgery, to 0.15, to 0.19, to 0.21 ng/ml over the course of several years. Their PSA never seemed to translate into anything. Looking at the differences in these cases raised questions in my mind.

Change in PSA is probably most important after treatment because the only thing that really affects it then is the disease itself. Before treatment, all sorts of things can affect PSA, making it a less reliable indicator of what’s happening with cancer. After surgery, it should be coming down and stabilizing or staying undetectable. When you see a rapid rise in PSA after treatment, you know that patient is going to have trouble soon. We don’t know whether having more treatment immediately is better for this patient than deferred treatment, but that question has spurred clinical trials. Looking at PSA changes after treatment also helps us stratify patients and determine which patients should enroll in clinical trials of novel agents.

So if a patient’s PSA is doubling every two months after treatment, can you assume that the PSA was doing the same thing before treatment?

We can definitely correlate post-treatment relapses with pretreatment PSA velocity, or how quickly the PSA rises. We did a study showing that a pretreatment PSA that increased by more than 2 ng/ml in a year is the strongest predictor that the PSA will double in less than three months after surgery. That’s important because when the PSA doubling time is less than three months, the patient has a significantly shorter life expectancy.

Table 1: Predictors of biochemical recurrence at time of diagnosis

Although a number of factors contribute to your risk of relapse after treatment, the parameters below offer a simple assessment of your chances of recurrence, based on your clinical profile at the time of diagnosis.

Low risk (15% chance of biochemical recurrence within five years) Gleason score less than or equal to 6 and PSA less than or equal to 10 ng/ml and cancer stage T1c or T2a
Intermediate risk (40% chance of biochemical recurrence within five years) Gleason score of 7 (with no tertiary grade 5) or PSA greater than 10 ng/ml but no greater than 20 ng/ml or cancer stage T2b
High risk (70% chance of biochemical recurrence within five years) Gleason score of 7 (with tertiary grade 5) or 8 or higher or PSA greater than 20 ng/ml or cancer stage T2c or higher

How did your risk classification system develop?

The risk groups are really based on three parameters: PSA level; Gleason score, which assigns a numeric value to the cancer based on what it looks like under the microscope; and DRE findings.

When I first started practicing medicine, age was the only prognostic factor that was used to determine if a man with prostate cancer would have surgery or radiation. If he was young — less than 70 — he had surgery. If he was older, or not healthy, or both, he had radiation. All factors other than age were thrown out.

I felt we really needed to consider other factors and put some structure into the system. So we decided to figure out who didn’t do well after surgery or radiation. We learned quite quickly that men with high PSAs did poorly, as did men with high Gleason scores and men at advanced clinical stages of the disease. That became the basis for the risk system: if a patient had one of these high-risk factors — a PSA over 20; or a Gleason score of 8, 9, or 10; or a tumor that you could feel during a digital rectal exam — surgery or radiation alone wasn’t likely to be enough for that patient. We knew he’d need additional treatment.

Later on, we were able to show that these risk factors not only predicted PSA recurrence, or biochemical recurrence, but also death from prostate cancer. That’s when risk classification became clinically relevant. [See “What’s biochemical recurrence?” below, and Figure 1 and Table 1, above.]

What’s biochemical recurrence?

Biochemical recurrence is an increase in PSA level following treatment, indicating that prostate cancer has returned or spread in spite of treatment. Biochemical recurrence may also be called PSA recurrence or biochemical failure. The degree of PSA change that constitutes biochemical recurrence depends on whether the patient had surgery or radiation as the primary therapy.

But those aren’t the only factors you consider today, are they?

I’ve often said that those three factors — PSA, Gleason score, and physical exam findings — aren’t enough to figure out which group a man falls into. Today, we put icing on the cake. We have PSA velocity, which can move a low-risk patient into a high-risk classification. The presence of perineural invasion on the biopsy can reclassify a low-risk person as being at intermediate risk. If more than half of the cores taken during a biopsy are positive, a patient moves up a risk group. PSA may also be affected by testosterone levels. Men with low testosterone actually have higher PSA levels than what the PSA test shows. For example, a patient with very low testosterone and a PSA of 2 ng/ml might be in the same risk group as someone with a normal testosterone level and a PSA of 10 ng/ml. In some cases, a patient may have a tertiary grade, too. [See “Tertiary grade,” below.]

So a lot of fine-tuning has occurred since the initial risk-based system was developed. But providing the original structure really helped people to further the idea. Now we have nomograms that treat the risk factors as continuous functions and yield a probability of failure from 1% to 100%. These nomograms essentially take the risk groups and make them points on a continuum as opposed to set categories.

Tertiary grade

The Gleason scoring system grades prostate tumor cells on a scale of 1 to 5 according to how they appear compared with normal prostate cells, a quality known as differentiation. Because tumors often consist of multiple types of cells, the pathologist generally assigns two values: the first to the predominant cell type, and the second to the next-most-prevalent cell type. The two values are added to come up with the Gleason score.

Although the system does not incorporate a third cell type, more than two cell types can occur in a tissue sample. If that happens, the pathologist may assign a third, or tertiary, grade. Having a tertiary grade 5 cancer may alter a patient’s prognosis and treatment decisions.

Backing up, how did you determine that a change in PSA greater than 2 ng/ml in the year before diagnosis meant a higher risk of prostate cancer death?

We looked at data from more than 1,000 men with a median PSA of 4.3 ng/ml who were screened and diagnosed with prostate cancer and then had a radical prostatectomy. We then looked at the men who had a change in PSA in the year prior to diagnosis and divided them into four groups. The first group had a PSA change of 0.5 ng/ml or less; the second group, 0.51 to 1 ng/ml; the third group, 1.01 to 2 ng/ml; and the fourth group had a change greater than 2 ng/ml in a year. We found that the men in the first, second, or third group did fine. Prostate cancer death rates were very, very small at 10 years — about 1% following surgery. But for those in the fourth group, the death rate from prostate cancer was huge — up to 28% within seven years of radical prostatectomy. We saw that and we were struck. [See “PSA velocity after surgery,” below.]

One thing to keep in mind about PSA velocity that is not in the study report, but which is true, is that when we refer to people in the cohort with “velocity greater than 2 ng/ml,” we’re including men whose PSA velocity was 2.1, 6.5, and so on. Since there’s no upper limit, the relationship of PSA velocity to cancer death is going to be driven by those at the extremes. I don’t want people to think there’s something magical about a change of 2 ng/ml. Of course, that’s what was published, so everybody remembers it, but 6 is worse than 4, which is worse than 2.5 ng/ml. The bigger the change, the worse it is. For a man with a velocity of 2.1 ng/ml in the previous year, his absolute risk of death from prostate cancer is nowhere near the 19-fold increase that was mentioned. His absolute risk is closer to 1.4.

PSA velocity after surgery

You mentioned perineural invasion. Can you give us your thoughts on that? Not everyone believes that’s an important pathologic finding on a biopsy.

There are a couple of studies that have looked at cancer death in otherwise low-risk patients with and without perineural invasion [PNI], or cancer around a nerve, on the biopsy who have been treated with radiation or surgery. They show that about 5% to 10% more men who were at low risk of disease progression die of prostate cancer within 10 years of treatment if they had PNI. [See “Impact of PNI,” below.]

We know that PNI can mean that there’s higher-grade disease or that there’s extracapsular extension. But I don’t want people to think that every man with low-risk disease and PNI has an increased risk of death. That’s not true. However, there is some subset of men with PNI who truly don’t have Gleason 6 disease. They’ve got Gleason 7 or 8 disease, and PNI is often a harbinger of higher-grade disease, but not always.

Impact of PNI

Perineural Invasion Associated with Increased Cancer-Specific Mortality after External Beam Radiation Therapy for Men with Low- and Intermediate-Risk Prostate Cancer.

Is that generally accepted?

Some people have found a relationship, but others have not. This gets back to my point that not every patient with PNI is going to have a worse outcome. If a man has had a 12-core biopsy and one core shows PNI and Gleason 6 cancer, he’ll probably be fine. But someone who has had a 12-core biopsy with seven cores that show Gleason 6 and PNI is more likely to have trouble.

How you handle that depends on how you think as a physician. I take the stance that I would rather overtreat 10 people than undertreat one. What’s the price of overtreatment? Hormone therapy, which I would add to radiation therapy. I tend to use short-course hormone therapy, which is six months of hormone therapy, in patients with PNI and otherwise low-risk disease.

When do you use hormone therapy in addition to radiation?

I will use it for anybody whose disease is not strictly low-risk — and not just by the original D’Amico criteria. Let me outline it. In order for a patient to get monotherapy [a single therapy, such as radiation therapy alone], without hormone therapy, he has to have a Gleason score of 6 or lower, with less than half the biopsy cores being positive, a cancer stage of T1c or T2a [see Figure 2 below], a PSA that doesn’t exceed 10 ng/ml, and a PSA velocity that doesn’t exceed 2 ng/ml in a year, and he cannot have PNI. Nor can the patient have low testosterone, because if he does, as I said, his PSA is not valid.

For anyone who doesn’t meet those low-risk criteria, I will add a short course of hormone therapy to radiation therapy. That includes patients with a Gleason score of 6 or higher with more than half of their biopsy cores positive for cancer; patients with a Gleason score of 7 (4 + 3) or higher; patients whose cancer is a stage T2b or higher; and patients with rapid changes in PSA.

I’d think through some cases a little more carefully — for example, take a patient with a Gleason score of 7 (3 + 4) and five of 12 cores positive, no PNI, stage T1c disease, and a PSA score that was 3.5 ng/ml a year ago and has gone up to 4.1 this year. Does he really need combined therapy? I would look at his family history. I would look at his ethnicity. I would see whether he was regularly screened for prostate cancer or if it was picked up in just the second year of screening. I would also look to see if he had had any prior biopsies. I’d factor these other things into my equation to figure out his treatment. If I can’t find anything else that would affect his risk, I’d recommend monotherapy.

What about the percentage of cancer within a core?

That’s more controversial, but we’ve looked at that, and others have too. Given the possibility of sampling error, if a man has two positive cores out of 12 and each core has 100% involvement, it’s hard to know if that really puts him into a higher risk category. You can get lucky and hit the exact spot where a small cancer is and get two cores that are 100% cancerous. But if you find that six of 12 cores are positive, that’s not just luck. There’s definitely something there, regardless of the percentage of cancer within each core. So I just look at the number of positive cores.

Didn’t the European Organization for Research and Treatment of Cancer (EORTC) study the use of hormone therapy in the same types of patients you’re describing?

The patients in that study were a bit different. Some of them had locally advanced prostate cancer, meaning they could have extracapsular extension or seminal vesicle invasion. They could have stage T3 or T4 disease as long as it didn’t involve regional lymph nodes. That’s more advanced disease than what I’ve been describing. The men in that study also received three years of hormone therapy. [To read this study’s findings, see “Radiation, hormone therapy, and the EORTC,” below.] I don’t question giving them hormone therapy and radiation, but did they need hormone therapy for three years? That study started in 1987, and I think we’re a lot smarter now about hormone therapy than we used to be.

Radiation, hormone therapy, and the EORTC

Bolla M, Collette L, Blank L, et al. Long-Term Results with Immediate Androgen Suppression and External Irradiation in Patients with Locally Advanced Prostate Cancer (an EORTC Study): A Phase III Randomized Trial. Lancet 2002;360:103–6. PMID: 12126818.

Bolla M, Gonzalez D, Warde P, et al. Improved Survival in Patients with Locally Advanced Prostate Cancer Treated with Radiotherapy and Goserelin. New England Journal of Medicine 1997;337:295–300. PMID:9233866.

So who should receive longer-term hormone therapy?

I’d be inclined to prescribe two years of hormone therapy, or even a little more, to a man who has high-grade cancer and is young. Although it’s not definitive by any means, a retrospective study will be published later this spring in the International Journal of Radiation Oncology, Biology & Physics showing that it may not be how much hormone therapy you give, but how long the effect lasts — that is, how long the testosterone stays at castrate levels predicts a patient’s longevity with regard to cancer death.

We looked at 206 men who received six months of hormone therapy and radiation or radiation alone in a randomized trial. We measured their testosterone levels at the start and then every three months after the end of hormone therapy. We were able to show that the men who lived the longest, or were the least likely to die from prostate cancer, were those whose testosterone remained suppressed to castrate levels for at least two years. And those men tended to be older; their testosterone rebounded more slowly. The younger men tended to rebound more quickly. So, in my mind, whether you need to give long-term hormone therapy to an elderly gentleman is a question. But for a younger man, you’d be foolish not to do it.

Figure 2: Prostate cancer staging

Prostate cancer staging: Stage T1a

T1a: Cannot be felt during a digital rectal exam (DRE); is found by accident, such as during treatment for benign prostatic hyperplasia (BPH); less than 5% of tissue is cancerous.

Prostate cancer staging: Stage T1b

T1b: Like T1a, but more than 5% of tissue is cancerous.

Prostate cancer staging: Stage T1c

T1c: Cannot be felt during a DRE; is detected when an elevated PSA leads to a needle biopsy.

Prostate cancer staging: Stage T2a, T2b, T2c

T2a: Can be felt during a DRE, but the cancer fills less than half of one lobe (not pictured).

T2b: Like T2a, but cancer fills more than half of one lobe.

T2c: Like T2a, but cancer is detected in both lobes (not pictured).

Prostate cancer staging: Stage T3, T4

T3: Cancer extends through the prostatic capsule and may invade seminal vesicles.

T4: Like T3 disease, but the cancer invades other structures, such as the bladder neck or rectum (not shown).

Most doctors use the tumor, nodes, and metastases, or TNM, system to stage prostate cancer. T represents the extent of the cancer: T1 cancers are the smallest, while T4 cancers are the largest and most diffuse. N indicates cancer in the lymph nodes. M means that distant metastases have been detected. (Diagrams don’t show lymph nodes or metastases.) Some of the more common tumor stages diagnosed today are shown above.

Technology and decision-making

When do you use magnetic resonance imaging (MRI) with an endorectal coil* in your decision-making?

That’s evolved over time. We published the results of a study suggesting that the best yield for this technology in terms of sensitivity and specificity is in the patients at intermediate risk. In low-risk patients, it has very little utility because it’s almost always wrong. The only time it’s right is when it shows seminal vesicle invasion, and that happens in only 2% of low-risk patients. If you want to cross all of your T’s and dot all of your I’s, then you could do this test in all low-risk patients, but only two times out of 100 will it give you something that will change patient management. I’ve also learned that you don’t need to do it in patients at high risk because you already know their cancer is extensive.

I use endorectal MRI most commonly in patients who have more than one determinant of intermediate risk — that is, if they have a nodule and a Gleason score of 7, or a nodule and a PSA level over 10 ng/ml. If patients have only one determinant of intermediate risk, such as stage T2b, MRI isn’t likely to be very helpful. But if they’ve got multiple determinants, the yield is much higher. That’s when it becomes more cost-effective and clinically useful.

What about the anatomic location of the nodule?

Every study I’ve read, including one from the University of California–San Francisco published in Radiology last year, concludes that MRI in the right patient population will clearly show extracapsular extension about 80% of the time. But because the images can be so hard to interpret, what we think is the actual location of a nodule turns out to be right only about half the time. Therefore, I don’t use it to determine whether to spare a nerve on one side or the other, because I think the images can fool you.

But you have used MRI to help guide the placement of brachytherapy* seeds, haven’t you?

Yes. I’m really proud of that work. I think it allowed many people to maintain their quality of life because they suffered fewer side effects. In a very select group of low-risk patients, we differentially dosed the brachytherapy seeds throughout the prostate. The peripheral zone, where most cancers arise, got the full dose. The transition zone, where the cancer is less likely, got about 80% of the full dose. And the anterior base, where these select patients often have no cancer, got half the full dose. With that lower dose at the anterior base, the urinary retention rate, the rate of acute, long-term urethral stricture [narrowing of the urethra], and the incidence of rectal damage were all markedly reduced.

One of your editorial board members, Dr. James Talcott, studied quality of life in men treated with brachytherapy and proved that patients had better quality of life with regard to gastrointestinal and genitourinary function in the months after the procedure when the MRI approach was used compared with the traditional use of ultrasound alone to place the seeds. [See “Seed placement and quality of life,” below.]

Seed placement and quality of life

Seo PH, D’Amico AV, Clark JA, et al. Assessing a Prostate Cancer Brachytherapy Technique Using Early Patient-Reported Symptoms: A Potential Early Indicator for Technology Assessment? Clinical Prostate Cancer 2004;3:38–42. PMID: 15279689.

So you’re not worried about tumors in the anterior base of the prostate?

In this very select group of people, we rarely see anterior base tumors. Period. When we do, they are usually cancers that have grown from the peripheral zone anteriorly. But in a very low-risk cohort, that shouldn’t be the case.

We’ve treated almost 800 men with this approach. Five years later, the PSA control rate is 95%. That’s not only because of the technique, though. It’s also because of the patients we select. When the 5% who experienced biochemical recurrence had saturation biopsies, the cancers that were found were not found in the anterior zone. They were actually found in the transition zone. So I think the anterior base can be spared in this select group.

Couldn’t you use ultrasound to place the seeds in the same way?

In a way, we do. It’s called MRI-ultrasound fusion. We do an MRI and an ultrasound and fuse the images together. That gives us more information. This is the technique we currently use to place brachytherapy seeds.

Can patients who live in rural areas have MRI-guided brachytherapy?

It’s unlikely. They can get ultrasound. MRI-ultrasound fusion is a software package that hospitals can buy, but they need to have a physicist who is savvy enough to know how to use it. It’s available in institutions in or near large cities, but if you’re far from any major institution, you’re not going to find it.

Biochemical failure: What’s next?

At the beginning of our discussion, we talked about biochemical failure, or biochemical recurrence. How is that defined?

After surgery, biochemical failure occurs when a patient has a PSA level greater than 0.1 ng/ml on two consecutive PSA tests. After radiation, it’s not as straightforward; the definition of biochemical failure keeps changing. The most recent one is the Phoenix definition, which is the PSA nadir, or low point, plus 2 ng/ml. I understand the reason it was changed — it alerts you to the most significant failures, the ones that lead to distant metastases and cancer death. But it’s really understating all the PSA failures.

You might say that’s a good thing because patients who have very protracted PSA failures may have disease that never becomes clinically significant. I think the reason the new definition was adopted is that older men typically have radiation therapy, so a protracted PSA failure for them might never be a problem. But when younger men have radiation therapy, particularly brachytherapy, I think it’s more relevant. Indolent PSA failure in a man who is in his 50s could become cancer death.

Personally, I think the definition of PSA failure should factor in the health and age of the patient. For a younger man undergoing radiation, I will use the same definition we use in surgery, and that is anything above the nadir.

You see a lot of patients with biochemical failure after primary therapy with surgery or radiation. Obviously one plan won’t work for all of them, but how do you counsel them?

I look at all the factors that are relevant. I look at their age and their health. I look at how quickly their PSA is rising, their Gleason score, and the time interval to biochemical failure. I then consider two questions: First, “Does something need to be done and if so, when?” Second, “What’s the anxiety level of this particular patient?”

Let’s start with the patient who is not anxious, which is rare. If he is not anxious, then I look at his age and health. If he’s older, has other health problems, and his PSA is rising slowly, meaning a doubling time longer than a year, I will not treat him. But if he’s young and healthy, I will recommend that he see a medical oncologist to discuss early treatment, because I think those are the people where we don’t know, given that they’re going to live long enough, that early treatment may not be helpful.

Now, if a man’s PSA doubles rapidly, meaning in less than six months, I have a tendency to treat, even if he is old and frail. But if he’s had radiation already, should he get hormone therapy? If so, should he get continuous or intermittent hormone therapy? [Intermittent hormone therapy involves alternating cycles of treatment and no treatment.] These are unanswered questions. For young, healthy people, I favor continuous therapy. For people who aren’t as healthy, I favor intermittent therapy. I also watch their testosterone levels because I’m not sure that older men or men with other health problems recover their testosterone as quickly as younger, healthy men.

What do you do if the patient is anxious?

If he’s anxious, all of this changes. You can’t say, “I’m not going to treat you,” and send him out the door. Instead, I talk about intermittent therapies or clinical trials. That way, the patient feels like he can do something, and that helps with the anxiety. The anxiety level in this population is huge.

What do you do for patients who experience biochemical failure following brachytherapy? Do you re-treat them if there’s a localized recurrence?

Let’s consider a man who’s in his early 60s and has a while to live, has no other illnesses, had low-risk disease to begin with, and his PSA is rising very slowly, consistent with a local recurrence. He has three choices. The first option is salvage prostatectomy, but not many doctors do this procedure. And the patient who is considering it needs to have his eyes open because the risk of serious side effects, such as permanent incontinence, is great.

Salvage cryotherapy, which involves freezing tissue, is another option. But I don’t favor it, mainly because you have to put a warmer in the urethra to protect it. At the apex, which is where a lot of the recurrences are, the warmer will heat the prostate tissue and the cryotherapy will not be effective. I’d stay away from it.

The third option is intensity-modulated radiation therapy (IMRT), CyberKnife, or another form of radiation therapy. The patient would have to have a saturation biopsy of 40 or more cores so you could tell exactly where the tumor is located before you start the second therapy. But there will still be side effects. Even with MRI-guided salvage brachytherapy, we have shown that 10% to 15% of patients will have complications that require surgery, such as a colostomy or urostomy.

What about high-intensity focused ultrasound (HIFU)?

HIFU is investigational, so if a man wants to go that route, he needs to know that it’s not a routine procedure. It needs to be done, in my opinion, as part of a clinical trial.

So you categorize patients as low-risk if their PSA doubling time is greater than a year and high-risk if it is less than six months. What about patients in the middle?

A paper in The Journal of the American Medical Association looked at this question. The researchers looked at PSA doubling times of less than three months, three to nine months, nine to 15 months, and more than 15 months. The patients in the first two groups did poorly. The patients in the nine-to-15-month group did fairly well. [See “PSA doubling time,” below.] So as the PSA doubling time gets closer to a year, you’ve got about 10 years to play with. In a younger man, that’s not very long, so I would start treatment, probably radiation therapy combined with hormones. But an older gentleman could be fine; you could start hormone therapy at a later time, maybe when his PSA doubling time drops or when he becomes symptomatic.

With so many different types of patients and so many possible treatment scenarios, as well as the fact that so many patients are being diagnosed with prostate cancer much earlier, does your original risk classification system still help stratify patients and inform treatment decisions?

The risk classification system will continue to be clinically useful until genetic-based molecular markers have been found and shown to be effective — and until testing for them becomes available. In the future, we will be able to use gene signatures to help determine a patient’s best course of treatment and prognosis.

    There is a difference between the grade Gleason score ! Just so people understand my boyfriend was Diagnosed stage for prostate cancer lymph nodes and was in bio Chemically in remission for two years now he’s taking a turn for a bio chemical reoccurrence which means as a PSA rises so does the cancer to rule out all odds doctors must do testing bone densities and other scans to see if there’s any visible evidenceOf the cancer spreading two other organs of the body or in the same regional area because he is not a candidate for salvage radiation we wait and see what doctors will put together as far as treatment goals every one is different this cancer is a very symple or complicated cancer because there is 3 types drs will tell you oh well your osa went up a bit because you just had sex Exercised no no no it’s the cancer that’s making it rise !!! D.R. don’t know and the Patients Live in limbo smh if they don’t know how we supposed to know ??? I think everyone deserves to know the truth!!! Blessings to all that have been touched by cancer 🙌

    Roger. 75years
    Had a RP 2012 at Mass General. The sutures let go and i almost bled to death. Was told cancer was contained,no follow up needed. Forward to feb 18 2018 Psa came in at-3.2,june 18-6.1 Started on Eligard, testosterone suppression treatment today. DR. said the cancer was aggressive and the prognosis is most likely 4 years.
    Goes to prove medicine’s got a long way to go. They is no cure, only management and God.

    Get2nd opinion. Some people are given 4 mos live 5 years or more.

    I am 92 years old. Had radical prostatectomy at age 66 when PSA was 5.3 and Gleason 8. Have taken hormones (Casodex, etc.) for past 10 years. Recently PSA went from 0.9 to 2.5. Also have very frothy urine. Doctor suggests Lupron. Is it really necessary?

  5. Faye

    psa 42.8 sorry

  6. Faye

    I just recently went to doctor with my fiance. His psa is 24.8. Exam found a nodule and a biopsy is being preformed Friday. The
    doctor told us it was Cancer and stage 4. I am at a lose, how
    can he possibly tell us this without a biopsy. Any thoughts,
    advice can be used now. I am begging Fiance to get a new doctor.
    I also worried about this doctor performing biopsy since he told
    us he had a patient die from ignoring symptoms after procedure
    was done. I know any procedure comes with risks. Scared beyond
    belief right now. Thanks in advance

  7. cj

    Very good Silverback female. I am going to fight my prostate cancer naturally…not risking what others did( ie: prostate removal, chemo. radiation etc..) but what I will be doing is a risky too…. God is in control. No worries!!!!

  8. Silverbacked Female

    My husband is doing a fruit diet and herbs.
    His PSA doubled and he is into the mid 40’#s now —age is 69
    Takes a long time to detox so it’s long haul, but he is not symptomatic tho the almost killing procedure of biopsy has showed some mild +signs and MRI last year showed some capsule involvement. He feels fine, and raw fruit has been a big adjustment. Cancer is just dis-eased cells so the body wants to fix it if you give it the right power of high energy fruit and the protection of well grown herbs in the right type and amounts. Dr. Morse of Port Charlotte can support this type of detox. Not for the weak of mind, and we are thinking a lifestyle change forever will be required with diet regardless. Stop eating proteins like meat and dairy goop and plugging up the lymphatic system with grains. The north american diet is killing us and drugs are snuffing symptoms but not looking at the cure. Chemo is acidic and that is killer to your cells- all your cells! Pain is a sign of acidosis. So all your arthritis, lupus, etc. Of course Coca Cola can eat you away too even faster. Don’t get me going on the side effects of diet soda. But look into Dr. Morse if you can handle it, take it slowly, and wear the cloak to wellville. Or don’t, I don’t care if you do or not. We all must find our path and our spirit to reach the higher enlightenment. Our medicine of today will never do this-and that is truth enuf for us to keep on keeping on. Best to all going along this road, see you in the next. Take what you need and leave the rest behind. Trust that you will hear and see what you need when you are ready. Stop thinking so much and just observe. It is so easy to get caught up in the ego. There is unfortunately huge ego in medicine. Try to keep it simple and understandable. Recall your roots! Power On.

    I am amazed atthe relative youth of many of those writing in. I am
    85 suffered a heart attack at age 37. I take Asprin one tablet daily I show none of the six signs of the prostate with PSA 10. I
    have what was considered to be Arthritis, but does not cause me any
    difficulty. I believe that considering all the side effects of the
    various treatments. I should perhaps leave well enough alone. What
    neither parent suffered fro m any cancer. What do you think?Anthony

  10. John

    Diagnosed 11 months ago with Gleason 3+4, stage 2. PSA was 19. I have had an enlarged prostate my entire adult life, I am 69. Tried HiFu, cryosurgery, they won’t do because of enlarged size at .97volumne. I’ve been on hormone therapy, casodex, proscar to help shrink. Cancer is in one lobe. Just had PSA test, dropped to 2.3, not sure how to take that. I can not get a clear answer, cause my Urologist just wants to do surgery. Thinking about watching a little longer and retest. Any thoughts?

  11. Marcus

    I’m 52 years old.I did get relief by taking a herbal medicine called Diuretic and Anti-inflammatory Pill . Maybe it can relieve your symptoms too.

  12. Gordon Cole

    I am 76 yrs old with a PSA of 4.30. I had radiation therapy 10 years ago and PSA results since then have averaged about 2.0 with a low of 0.8 and a high of 3.0. My last test was 2 yrs ago at 2.16. What’s my prognosis?

  13. Deb Rouis

    Did you know that you have a post from Dr. Ronald E. Wheeler with contact information who was arrested this year for practicing without a license in Sarasota, Florida?

  14. richard C

    I am 67 years old and during my annual physical my PSA was .05. My MD performed a DRE which he advised was normal. My father died of prostrate cancer in 2012, so I have a family history and I am concerned. During my prior annual physical in 2016 my PSA was .03. Should I be alarmed at the rise in PSA. Should I have further testing?

  15. charlie meyers

    i was dx with prostrate cancer 2008 Gleason 5 or 6 the total score was like 10?. went thru the radiation and it was contain a yr ago with zytiga and predinsone never more then 4-5 then they took me off and was just taking casodex. will this yr psa went to 11.8 and three months later 11.5. a doctor at cancer nw in my town thought my cancer was localize in the lymph nodes in the groin area. so again was radiated for 31 days and got my results. now my psa is 26.67 2 months after the radiation. they are going ahead of cat scan and bone scan. i know if its metasis hopefully there is drugs out there. my doctor thinks i should be on lupron shots for ever even though the last score was 8

  16. Marnie G

    My husband had high risk prostrate cancer diagnosed less than 2 years ago, had robotic removal and then had radiation for thirty three days. His PSA has been rising going from 0.07 to 0.12 in less than three months and now is 0.41 three months on. Guess we’re wondering what happens now. When should hormone treatment start? What scans should he have etc. In addition to the rising PSA he’s also had a year of urinary bleeding from radiation cystitis and regular admission to emergency for retention from clots. He’s had recent heart surgery for a device to allow him to go off blood thinners and have six weeks of daily hyperbaric treatment which will hopefully address the blood loss (daily with any movement) and now this PSA scare is something else again!

  17. My friend has stage 4 prostate cancer lymph nodes lower back next to the spine 43 treatments of radiation to the regional area plus trelstar hdt shot Dr says his cancer is at bay are you could say readmission biochemical and undetectable PSA his last PSA was 0.02 this month 0.01.. no more sites for him no more treatments no more nothing nuclear bone scan MRI X-ray CT scan PET scan nothing now we wait six months what are we waiting for and what is going to happen he is age 54 diagnosed in States for September 2014 can you please help answer this missed questions by doctors I get no concrete answers as a care aide thank you

  18. Greg Spirou

    May 20th 2017
    I had prostatectomy 12 months ago at the age of 62. PSA before operation was 15 with a Gleason score of 8. After surgery my PSA for the most part was stable at .02 (during the first 11 months). The next reading it went up to .03 and then came back down to .02.
    Two weeks ago i had another blood test and this time it was .25 (3 weeks before it was .02) I spoke to my GP assuming this was a mistake so i had another within 2 days of the .25 reading and this was worst, .3
    How can PSA go up so quickly at such short period of time. Has anyone heard of this before? Please help i am panicking.

    • Maria

      we are asking ourselves the same question my husband’s PSA was it 26.3
      And then 10 days later he got another blood test and now it’s 41.2
      I am not sure if we should be freaking out either
      Is this normal he is on a clinical trial and since he’s been on it it went from a 12 to a 41 and two months

  19. Candace

    My father (68) was diagnosed with prostate cancer 11 years ago. He went thru 38 treatments of radiation and 27 months of therapy. Last spring (he is now (79) we were told the cancer had metastasized to his ribs. He went thru more therapy and we were told the cancer was undetectable. We continued treatment, but his psa continues to climb even tho in treatment. Has anyone had an experience like this? Can you share with me how much time he has. The doctors aren’t saying.

  20. simon shrestha

    My Dad
    A cancer patient, passed away after 4 year battling with prostate cancer at the age of 75. He was lucky man. I consider him as luck man as he should not bear to see any other pain in this world where we born to die. He was treated with radical prostatectomy, hormone therapy and chemo. But not radiation. As there are different stages and different types of prostate cancer a Dr should give treatment as per above mentioned stages and types. Since cancer itself is very aggressive decease, it’s treatment also should be aggressive. We shall not left room to treat it as in the case of my Dad. He was not treated with radiation. he has 10 Gleason score, HRPC, 22 PSA and stage 3c. None of the medicine stop his cancer for more than 2 month. Including chemo like Taxotere, Fytoside and carboplatin, CAMPTO and other such as Elligard, Zytiga, Honvan, cancer caught him in the middle of his journey.
    During treatment with chemo his PSA was down to 0.2 but still has cancer all over his body seems like cancer cell adopt to live with chemo and feeding on it instead of dying. At the end he seems to have small cell A. Carcinoma which is the most rare type of cancer probably 2%. I suggest to all to use all type of treatment till it is possible. Do not wait and take chance.

    God bless to all cancer patient and his family.

    thank you.

    Age 58 Had prostrate removed in January. All well except 1 of 9 lymph nodes had a 1mm of cancer. 2 psa’s undectable. Some doctotors say I’m possible cured. I am skeptical. No radiation or hormone. Any thoughts PLEASE My doctor says 50% 50% chance it wont return


    Dear Sir,
    I am 62, I was operated 2 years ago with radical robotic protatectomy, with a PSA 5,17, Gleason 3+4=7, 2Tc.
    I didn’t have any therapy untill now.
    I feel good, with a normal style of life.
    My PSA level was in the last 2 years from: 0.003,0.011,0.018,0.019,0.030,0.030,0.045,untill 0.066 checked every 3 month.
    I had every year CT control with nothing found.
    Is this still in a normal range or should I worry because is slowly increased?
    Please let me know some information, because I am from Romania with not good experienced doctors in this field.
    Many thanks,
    Zoltan Darabont

    I’m now 79 & have moderate bph, urinate 3 or four times in the morning usually & maybe 6 to 7 times ea 24 hrs.
    & my bph score is usually .7 it .8 but not higher.

    Is it advisable to buy a sol palmetto product to take daily or is there a suggestion?

    I’m a 65-year-old, and I have prostate cancer; I live in Colorado; I got my original biopsy when my PSA jumped from 4.7 to 6.9, in the span of two months.

    After conferring with my urologist, I began the Rick Simpson protocol for programmed cell death in cancer. It requires ingesting 60mg of THC over 90 days.

    At the 70 day point, I had my PSA tested. It came back 4.0. We’ll be testing again in 30 days.

    I have experienced a few side effects; my arthritic elbows, thumbs, and hands, don’t hurt. The depression that has wracked me for 5 years is gone; I’m not stoned. I barely feel the meds.

    Rick Simpson protocol is a viable, mix-it-up-in-your-sink cancer cure. It’s cured 5000 people; it’s curing me.

    I am 77 years old with PSA level of 9 ( R 97.2) and a Gleason score of 3+4. Rectal exam did not find any bumps or hard areas. I had biopsy with cancer in 5 of 12 samples. My Doctor recommended radiation for 8 weeks . I am not sure if I should take radiation due to fact that I have arachnoiditis which cause sever pain.

  26. gordon tate

    At age 55 my psa went to38 from 2 at age 53. my gleason was 4&3 I immediately had a biopsy with cancer in 4 of 12 samples. I was put on various hormones for 18 months after which the psa dropped to 1.5. Then it was radiation followed by radioactive iodine12 pellets(77 pellets due to my small prostate). I thought I was a goner but it has been seven years with a psa of .02 I read where pomegranate juice at 6 ounces daily can reduce the double time a lot. I also exercise vigorously and eat a very healthy diet except for red wine. I also take vit. d because I live on the wet west coast. A positive can due wonders and keep your sense of humour if you have one,if not get one.

  27. Joe Douglas

    I am 75 years old fit and still working I was diagnosed with a recurrence of prostate cancer after 10 years clear after brachytherapy. I ad a MRI of my pelvic area and a pet scan and there was no sign of cancer spread outside the capsule and the prostate margins around the capsule clearly defined. Only my PSA has increased to 30.4 over an 8 month period( 10 years ago it dropped to 1.4 after brachytherapy)I suffer on and off with prostatitis and although tested nothing shows infection wise but I have all the discomfort with it. I am booked in for a 68Ga-PSMA scan which is supposed to show up if there is cancer spread and is supposed to be a more precise diagnostic scan. Any advice on where to from here or comments on treatments available would be welcomed. Joe

    On chemical castration procedure after PSA slowly rose to 20.
    Would this person be in fragile health, physically/otherwise?
    Thank you. pf

  29. Thom Knott

    I was 47 and my PSA was over 4 and the decision was to watch and wait, within 12 months it had double. I had a gleason of 4+3 with PSA just over 8 and I chose external beam radiation and was monitored with again a PSA doubling oin 12 months from over 2 to mid 4 and we were prepared to do something more aggressive such and was at the time considering salvage surgery. Then a miracle occurred, PSA was sliding down over four quarterly tests to 2.02. Unfortunately, in the last 3 months it has again doubled. I have just turned 51 and I don’t think that I have made good choices by choosing radiation over surgery with no backup other than hormone surgery to slow it down. I have good years ahead of me but I worry that they may be to few, my mental disposition is good but the reality is that I am likely to die from this disease. I wish I had someway to know what to expect so that I could plan accordingly, I don’t want to work myself to the grave. Good luck to you all. Thom

  30. John

    I’m 64 had RP 11-17-15, PSA was 9.9, Gleason 3+4, 4+4 after surgery. Had just left Stage 2 into beginning of Stage 3. Everything was clear. Altho capsule broken. Now 0.1 Going to first app in Feb to dIscuss options. Eliminated red meat, eating mostly fruits and veggies with few exceptions. Chicken occassionly etc. More walking altho 2 yrs ago injured lower back, which slows me a bit. Still have ED and wear pads at night. Feel well over all. Can anyone chime in on likely future? Radiation scares me have heard mostly likely to trigger bladder or rectal cancer later, adds to ED problems etc. Horomone acceptable but hear can mess with your brain, little for me to spare there. Thanks in advance.

  31. J W Ziervogel

    After robotic prostatectomy my psa was at 3 weeks post-op 48,6 weeks post-op 17.Later it dropped to 1.2 then 3months later rise till 7.4.Eventially it dropped to 5.4.Because no cancer was find in the dissected prostate,I still refuse radiotherapy.
    My urologist suspect that the medial lob of my prostate was left behind during surgery due to the fact that it had grown into the bladder wall.

  32. Ronald E. Wheeler, M.D.

    I am a HIFU treating expert and I have been for almost 10 years, having treated with both technologies.
    HIFU (High Intensity Focused Ultrasound) has been around for more than 26 years in Europe and Japan (primarily). HIFU has been approved by the FDA on November 9, 2015 for ablation of prostate tissue. In my experience, I believe HIFU is the best treatment when an aggressive prostate cancer is diagnosed with a Gleason Score of 4+3=7, 4+4=8, 4+5=9, 5+4=9 or 5+5=10 regardless of PSA value. This article from Harvard points out accurately that aggressive prostate cancer fails commonly regardless of treatment. This is true as the literature states recurrence with Gleason Scores of 8-10 is associated with failure up to 85% within 5 years so we should be looking at something other than radical prostatectomy or radiation therapy for cure. With any prostate cancer while survival is important and commonly achieved regardless of treatment, we need to be talking about cure. Cure and survival are two totally different concepts. I have had incredible success in dealing with high grade prostate cancer using HIFU* (with an asterisk) and welcome men with their wives to call us regarding consideration for cure. During the process of collating our data for publication, we have found an extraordinarily high cure rate for this aggressive class of cancer that arguably makes up 35-40% of all prostate cancer. I did say cure rate based on a nadir of less than 0.13 (PSA level) at more than 2.5 years. Of interest is our intellectual property that allows us to improve our outcome data in this very significant patient group. For best results with HIFU* (with an asterisk), we prefer a PSA of 8.5 ng/ml or less. If this factor is present, regardless of Gleason score, we have 100% of patients cured at 2.5 years. While we are continuing our research we encourage folks with interest to view our website ( or call us to set up a no obligation conference call. While we plan to continue this research we are heartened by the fact that patients are not failing within a year which is very common with radical prostatectomy with or without radiation. I believe we are on to something that will change medicine dramatically but only time will tell. I also encourage physicians with patients at high risk to give us a call toll free at 877-766-8400.

  33. Anne

    My husband was diagnosed in 2013 at age 41 with Gleason 8, tertiary 5. He had a radical prostatectomy thinking it was all contained. 6 weeks after surgery his PSA was 5. It had left his prostate, gone into his seminal vesicle and invaded 3 lymph nodes. He went on a clinical trial of Zytiga and Degarelix for a year that brought his PSA down to .02, then had a lymphadenectomy. His PSA remained .02 for several months until recently it went up to .05, then .06 a month later, then .08 another month later. He has started taking Degarelix injections again and will start Provenge in the next few months. Does anyone have experience with Provenge? Everything I read does not make it sound impressive. I am worried for the road ahead and feel like we are now on a slippery slope.

  34. Gary

    I was diagnosed with stage 3, Gleason 9 (5+4) prostate cancer in mid 2010 at the age of 49. I had Brachytherapy, 25 external beam radiation sessions and 18 months hormone deprivation. Initial psa was 8.2 in 2010. Note: I ate 300g tomato paste a day during and post radiation (i don’t know if this had a positive effect on my treatment….the lucoprene concentrates in cancerous prostrate tissue, maybe more absorbant?). it is now Oct 2015 my last psa was 0.04 ng/L. I also take one Ecotrin, slow release Asprin, a day (please read up the benefits of Asprin wrt cancer). Best wishes to all of you battling cancer.

  35. Dan

    I had surgery 12 years ago with for Gleason 6 PCA at age 44. Went 4 years and PSA started very slowly rising. I watched for 4 years until PSA went to .35 and had salvage radiation treatment. PSA dropped a little but never below .22. Over the last 4 years slowly going up and now at .58 but is at about a 3 year doubling rate. Please let me know any recommendations you might have. Age 57 now.

  36. Peter Dobson

    I was diagnosed 5 years ago at the age of 64. I had requested a PSA test from my doctor several times over the previous 5 years but he considered my concerns to be groundless and each time advised me that a test was not necessary or desirable. Finally a locum did the test and it returned a PSA of 125. By this stage my options were restricted to external beam radiation therapy and hormone treatment. Now 5 years on I am having intermittent hormone implants, the effectiveness of which is reducing as the doubling time gathers pace. Other drugs are coming on line however, and new treatments are becoming available. I have few illusions about my long term prospects but as I approach 70 I have overcome my initial bitterness at having been failed by the system and remain optimistic.

  37. Nancy

    6 years ago I WAS in your shoes. I had a 46 yr old husband with Stage IV, with lymph node involvement, Gleason score of 9, the Prostate growth had escaped the capsule. His PSA doubling time was so short that time he had not had time to grow bone metastasizes to show on a bone scan. My youngest had just entered the teen years & the oldest was in college. Advice: Seek good treatment. It sounds like you are. There is always a flurry of treatment that first year with a “youthful” prostate cancer.

    Prostate cancer is more like a chronic illness. My husband has continued to work. His cancer has progressed, but so have treatments for the cancer. Since my husband was diagnosed so young it is likely he will be someone that dies of prostate cancer. We are not near the end of the road yet, so take heart. My husband and I may not have the decades we had anticipated, but we’ve had years and still have more years to come.

    • John

      I had RP 11-17-15. My numbers had been rising slow but steady. I was seeing Dr. Lee at Kaiser in Southern Ca. Lee was pushing was for biopsy. Never offering less invasive alternative. At later time I asked his partner Dr Robinson if urine test was available I heard about. No was the response. At no time was MRI mentioned BECAUSE of cost it would appear. Much later my surgeon ordered up one TOO LATE for me.
      If I had known available would have paid out of my pocket. MRI shows capsule broken. Now stage three. I did not get what I paid for.
      In another example my wife’s knee doctor told her she had torn meniscus. She requested MRI and proved her doctor wrong and he was extremely upset with her.
      So don’t think the system can’t be wrong. Or won’t lie to your face.
      Now I have to deal with the nightmare Kaiser could have avoided. But money more important.

    • Jill

      I read your comment on here and am wondering how your husband is doing now (2 years after your post). I am currently in the same situation: husband in his 40’s with Gleason 9 and locally advanced cancer. 2 young daughters.
      Best Wishes.

  38. Kathy

    My husband is a 52 year old male with stage 4 prostate cancer. His PSA was 217 and his Gleason score was 9 with 12 out of 12 Biopsy came back positive.

    He has had a radical-prostatectomy, 9 rounds of Chemo, he is beginning radium 223 and radiation everyday for 5 weeks. My husband wants to stay positive and believes that his time here is between him and god! However, I want to know his life expectancy because I have 4 children 3 of which are going to college to know how limited time with their dad maybe. They have all asked me numerous times if Dad is gonna beat this and I told them I don’t know Dad does not want me to ask. Help please let me know your thoughts. I know you can not tell me about my husband specifically but can you give me the law of average with these scores. Thank you!

    • Mike baker

      Kathy your story was moving. My dad has prostate cancer. Was wondering how your husband faired his treatments? Did he have a family history?

  39. richard bowers

    Had RRP 16 years ago. Showed no detect until last test showed less than 3. doc was unconcerned. I less so. That test was months ago. Should I push for another?

  40. Sam

    My husband is 55 and has a PSA reading of 1300 with no other sign of prostate trouble or bone involvement Texotere brought his psa down to 200 then in 4 weeks it went up to 1300 :(– I’m so worried….

  41. Naga Leela Kumar

    My Father is 76 and having PSA reading of 950 with no other signs of prostate trouble. He went surgery in Nov 2013 and tenticles were removed. After that in Feb 2015 there is some prostate left which he underwent surgery and was removed.
    During Feb 2015 the PSA reading shows as 300 and currently it shows PSA reading as 950. He is having some pain in the back bone near the base. Can we go for chemo theraphy at this stage.
    Please do advice me.

  42. ishbel askew

    My husband is 76 and has a PSA reading of 1300 with no other sign of prostate trouble – what are his chances, I’m so worried….

  43. Grozde Aleksovski

    I am 60 years of age and I am having prostate CA with Gleason score 4+3=7. The cancer is also spread to the bones. I started hormone therapy 3 months ago. The PSA was 154 before the start of the treatment, and now it has dropped down to 11.95. Please comment this change of PSA level, whether it is normal, or it is exceptionally good, as I don’t want to develop false hope for fast recovery. When should I make additional tests (biopsy, bone nuclear screening, MRI).
    Thank you.

  44. Brian Haselum

    I am 68 years of age, prior to my radical prostatectomy in 2010 I had a Gleason score 4+3 =7 and T3 my PSA levels were post op 0.04 the began to rise again. 2011 Salvage Radiation therapy took place and PSA levels were 0.001 up until May this year PSA level was 0.018 and one this last November risen to 0.051. My doctor informs me that there can be no treatment to halt this rise as it is so small, and that consideration for Hormone therapy would be considered when PSA reaches 5.00. What advice can you offer,
