A new study shows that the risk for prostate cancer is significantly elevated in men who are part of families with a hereditary form of breast and ovarian cancer. Researchers at Memorial Sloan-Kettering Cancer Center have determined that men in families carrying BRCA genetic mutations have a three- to five-fold increased risk of prostate cancer.
"While the association between hereditary breast and prostate cancer has been suspected, this is the first study of its type to confirm the link," said Kenneth Offit, MD, Chief of the Clinical Genetics Service at Memorial Sloan-Kettering and senior author of the study, which is published in the May 1 issue of Clinical Cancer Research.
Researchers obtained DNA specimens from 251 men of Eastern European (Ashkenazi) Jewish ancestry who had prostate cancer but were otherwise unselected on the basis of personal or family history. The blood samples were tested for mutations of the BRCA1 and BRCA2 genes and compared to specimens taken from 1,472 healthy men. Investigators pinpointed BRCA2 – not BRCA1 – as the common genetic link to prostate cancer.
