Abstract:
Objective To investigate the correlation of positive margins after radical prostatectomy with Gleason score of biopsy specimens and percentage of positive biopsy cores in prostate cancer.Methods One hundred and thirty patients with localized prostate cancer were confirmed by biopsy underwent radical prostatectomy,the relationship between positive margins rate and Gleason scores,percentage of positive biopsy cores were analyzed.Results One hundred and thirty cases of biopsy specimens,Gleason score 6 group 50 cases,positive margins rate was 10.00％ (5/50),Gleason score 7 group 65 cases,positive margins rate was 21.54％(14/65),Gleason score 8 group 13 cases,positive margins rate was 0,Gleason score 9 group 2 cases,positive margins rate was 0,the positive margins rate among the different Gleason score group had no significant difference (x2 =5.917 5,P ＞ 0.05).All the statistics of percentage of positive biopsy cores were 89 cases,1％-25％ group 30 cases,positive margins rate was 3.33％ (1/30),26％-50％ group 27 cases,positive margins rate was 11.11％ (3/27),51％-75％ group 18 cases,positive margins rate was 6/18,76％-100％ group 14 cases,positive margins rate was 4/14,the positive margins rate among different percentage of positive biopsy cores group had significant difference (x2 =9.861 8,P ＜ 0.05).Conclusion There is no correlation between Gleason score and positive margins in prostate cancer,but there is correlation between percentage of positive biopsy cores and positive margins.
