title: Factors effective on survival after radical prostatectomy: To what extent is pre-operative biopsy Gleason scoring is confident in predicting the prognosis?
abstract: In the present study, the effect of different grades on independent survival from the biochemical relapse was investigated through comparison of the histological grades of the biopsy and prostatectomy materials in patients undergoing radical prostatectomy (RP). A total of 152 patients undergoing RP following biopsy were retrospectively investigated in an attempt to reveal the effect of discordance between needle biopsy Gleason score and RP Gleason score on prostate specific antigen relapse-free survival. Accordingly, while 58.3% (14/24) survival was seen in the patients in Group 1 (high-graded) with Gleason score 7, 93.7% (15/16) survival has been seen in the patients in Group 2 (low-graded) and Group 3 (same Gleason scores) with Gleason score 7. The difference in-between has been statically found significant (P < 0.001). Similarly, while a 10% (1/10) survival is seen in the patients in Group 1 with Gleason score 8 and above, 75% (3/4) survival has been observed in the patients in Group 2 and 3 with Gleason score 8 and above. Also in this comparison, the difference in-between has been statically found significant (P = 0.041). Eventually, different grading, particularly determination of Gleason score higher than the RP specimen biopsy also bring about bad pathologic parameters and shortened survival periods.
