Сomparative analysis of the histologic data before and after radical prostatectomy patients with low pre-operative cancer risk

Prostate cancer (PC) is the most frequent cancer among men in the world. At current PC takes 2nd place in men mortality among all oncological diseases. Histological grading is an important part of the diagnostic evaluation. The most commonly used grading system is the one described by Gleason. The choice of optimal PC treatment becomes complicated due to the fact that different methods have the same oncological results but differ in their complications. From a prognostic point of view, it is of considerable interest to know how accurate the needle biopsy Gleason score is in predicting the final score of the radical prostatectomy specimen. This paper describes comparative analysis of the histologic data before and after radical prostatectomy patients with low pre-operative cancer risk.
