865: Comparison of Preoperative PSA Velocity or PSA Doubling Time as a Predictor of Outcome after Radical Prostatectomy
Year: 2006
Type: conference-abstract
Abstract: included prostate and seminal vesicles.Clinical information was obtained from Center for Prostate Disease Research (CPDR).RESULTS: The mean age was 61 years, and mean preoperative PSA was 6.9 ng/ml.Mean prostate weight of the RP specimen was 42.6 gm.Mean index tumor volume was 5.7 cm 3 and mean total tumor volume was 6.7 cm 3 .Up to 50 gms, there was a correlation between preoperative PSA level, tumor volume and prostate weight.With increasing PSA levels, there was a parallel increase in prostate weight and tumor volume.However, when the prostate weight exceeded 50 gms, there was positive correlation between preoperative PSA level and prostate weight but an inverse correlation of tumor volume with PSA levels and prostate weight.CONCLUSIONS: In prostates exceeding 50 gms, preoperative PSA levels correlate with the prostatic weight but not with the tumor volume.In prostates less than 50 gm, the preoperative PSA level appears to correlate with both increase in prostate weight and tumor size.
