Free-to-total prostate-specific antigen ratio as a predictor of non-organ-confined prostate cancer (stage pT3).
OBJECTIVE: To evaluate whether the free-to-total prostate-specific antigen (F/T-PSA) ratio can be used to differentiate between stage pT2 and pT3 prostate cancer. MATERIAL AND METHODS: A total of 176 consecutive patients from the Göteborg Screening Study (median T-PSA 4.2 ng/ml) who underwent radical prostatectomy (without neoadjuvant hormonal therapy) were included in the study. The pT stage was correlated with classical risk factors such as T-PSA and Gleason sum and the impact of the F/T-P...Expand abstract
