The consistency of Gleason scores may effect the operation outcomes for laparoscopic radical prostatectomy: a single surgeon and a single pathologist data.

INTRODUCTION To evaluate the effects of consistency in preoperative and postoperative Gleason scores to the operation outcomes in patients who underwent laparoscopic radical prostatectomy. MATERIALS AND METHODS 204 of 347 patients were included the study. 143 patients whose preoperative prostate biopsies were evaluated in the other Institute were not included into the study. The preoperative data of patients and operation outcomes were investigated from institute's files of patients. Patients were divided to three groups by using consistence of pre and postoperative Gleason scores. The tumor, node and metastasis classification were used for staging prostate cancer. RESULTS Mean age was 63 and the mean PSA level was 11 ng/dl overall. In statistical analysis PSA levels, Gleason score and rate of positive score were significantly low in Group I (p < 0.05). As in operative data, nerve sparing surgical technique was performed statistical significance higher in Group 1 than other Groups. External bleeding rate of Group II was significantly lower than the other Groups. In univariate and multivariate analysis, postoperative pathologic stage was statistical significant for consistency of pre and postoperative Gleason scores. CONCLUSIONS The modified Gleason scoring system is safe and usable for evaluating prostate biopsies and operative specimens. The consistency in pre and postoperative Gleason score effect the operation technique and also operation outcomes. Working with an experienced uro-pathologist provides to inform patients more accurate and better.
