Abstract
One of the main reasons for the introduction of a new grading system was Gleason sum 7, which differed significantly in the prognosis of the disease depending on the primary Gleason. The aim of this study was to compare grade group 2 and grade group 3, and the impact of cancer percentages in final pathology reports after radical prostatectomy on the occurrence of T3 stage of the disease after radical prostatectomy of clinically localized prostate cancer. The study covered 365 patients with clinically localized prostate cancer who underwent radical retropubic prostatectomy (RRP) over the period of two years. The average percentage of carcinomas found in pathology reports after RRP was 20.1%. With the increase in the grade group, the average percentage of carcinomas in pathology reports increased significantly, p<0.001. With regard to grade groups 2 and 3, irrespective of cancer percentages in pathology reports, more cases of T3 stage were found in grade group 3 when compared to grade group 2, which was statistically significant (p<0.001). However, grade group 2 and grade group 3 patients with ≤10% cancer occurrences in final pathology reports after RRP did not show any statistical significance in the occurrence of T3 stage, p=0.96. Prognostic differences in grade group 2 and grade group 3 patients after RRP are significant, but not in all cases, because of their dependence on the percentage of cancer in the final pathology report after RRP of clinically localized prostate cancer.
