MedicalResearch.com: What is the background for this study?
Response: PSA screening for prostate cancer has long been controversial. While it does seem to reduce mortality attributable to prostate cancer, it also results in the diagnosis of many cancers that never otherwise would have presented symptomatically. In addition, PSA levels are affected by factors other than prostate tumors (e.g., age, prostatic inflammation, and genetics), such that men with high PSA values are often referred for biopsy but do not end up having cancer. We hypothesized that accounting for the genetic component of PSA could yield adjusted values that better distinguish who should get a prostate biopsy.
