A new calculation tool may help predict men’s prostate cancer risk
In the journals
Men may soon have a new way to help determine their risk for prostate cancer. Using a medical database of almost 17,000 men with prostate cancer, researchers created a model that calculated a man’s risk by focusing on family history of prostate cancer and genetic variants, specifically the genes BRCA2, HOXB13, and BRCA1, which are associated with a higher risk of prostate cancer.
The risk model was applied to a database of 170,000 men without prostate cancer. About 7,600 of these men developed cancer over a 10-year period. The researchers found that the majority of the prostate cancer patients could have been identified as moderate to high risk prior to their diagnosis.
The percentage of men expected to develop prostate cancer was 54% among those with a BRCA2 gene mutation, 39% for those with the HOXB13 variant, and 17% for those with a BRCA1 mutation, according to the model. When researchers looked only at family history, they discovered that men whose fathers were diagnosed with prostate cancer at age 50 had more than double the risk than those whose fathers were diagnosed at age 80.
The model is currently used for genetic counseling. If validated in additional studies, it could help better identify which men may benefit most from routine prostate cancer screening. The results were published online Dec. 9, 2022, by the Journal of Clinical Oncology.
