ABSTRACT
Objective To determine the relevant factors of under staging and under grading in patients undergoing radical prostatectomy and to define important predictors of under staging in this population. Methods The clinical T stages and biopsy Gleason scores were compared with the pathological T stages and prostatectomy Gleason scores in 55 patients. Results Among the 55 cases,50 were preoperatively classified as clinical stages T 1~T 2,of whom 21(42%) were postoperatively classified as pathological stages T 3~T 4.Of the 26 cases who preoperatively had the Gleason scores of 2 to 6,11(42%) had postoperatively pathological grades of 7 to 10.Logistic regression analysis revealed that PSA( P =0.0159)at diagnosis and the percentage of positive biopsies of prostate ≥50%( P =0.0013) were significant predictors for preoperative clinical staging lower than postoperative pathological staging. Conclusions The results demonstrate that patients who were classified as clinical stages T 1~T 2 with PSA≥20 ng/ml and percentage of positive biopsies≥50% may have high possibility of under staging.
