Boston, MA — Prostate cancer (PC) is the second leading cause of male cancer death in the United States with an estimated 26,000 deaths in 2016. Two-thirds of all PC deaths observed in the US are men with localized disease who developed metastasis. Several markers for dying from prostate cancer exist, but whether these are markers for telling who is likely to die early from any cause, and how their performance compares, is unknown. Identifying such a marker is important because we can then identify which men may benefit from new, more aggressive treatments for prostate cancer.
Researchers at Brigham and Women’s Hospital found that a prostate specific antigen (PSA) nadir (the lowest level a PSA drops after treatment) greater than 0.5 ng/mL following radiation and androgen deprivation therapy (anti-hormone therapy), appears to identify men prior to PSA failure who are at high-risk for dying early as a result of treatment failure for their prostate cancer. The findings are published in the January 12 edition of JAMA Oncology.
