New Study On Prostate-Cancer Screening
Amid an ongoing controversy about screening for prostate cancer, a new study says that prostate-cancer survival rates among patients with advanced cases have dropped since the introduction of PSA (Protein-Specific Antigen) testing. And the survival rate is now virtually the same for black men as for white men.
The study, reported in the “Journal of Urology,” was conducted by experts at the Fred Hutchinson Cancer Research Center in Seattle. The median overall survival rate for men with metastatic prostate cancer increased by 50 percent has increased since the introduction of PSA testing, according the researchers’ review of three previous clinical trials.
Because statistics from those trials had limitations, the authors of the Fred Hutchinson study didn’t definitively recommend early screening. But they did say that improved survival rates among black men might be due to “a greater awareness of prostate cancer and improved health-seeking behavior.”
Early this year, the U.S. Preventive Services Task Force recommended against routine PSA screening, saying that it discovered too many cancers that weren’t dangerous and were treated too aggressively.
