Five years after surgery for prostate cancer, African-American men reported better sexual and urinary function than non-Latino white men-yet they were also more dissatisfied with problems related to their sexual function, according to researchers from the Keck School of Medicine of the University of Southern California and colleagues. Investigators report the latest results from the expansive Prostate Cancer Outcomes Study (PCOS), a National Cancer Institute-supported study encompassing nearly 3,500 prostate cancer patients, in the Oct. 15 issue of the Journal of Clinical Oncology. The study is one of the nation's largest and most representative on quality of life after prostate cancer.
