Comparison of histopathological features, survival, and oncological outcome between patients under and above 55-year-old with prostate cancer who underwent radical prostatectomy

Background: To compare the disease course, histopathological features and survival rates of prostate cancer (PCa) between patients aged ⩽ 55 and > 55 year old. Materials and methods: In this retrospective study, we enrolled 644 patients with organ-confide prostate cancer who had undergone radical prostatectomy from 2005 to 2018. Seventy-six (11.8%) patients were under 55 years of age (group 1) and 568 (88.2%) patients were >55 years old (group 2). Results: Pre-operative hypertension was detected in 4 (5.3%) patients of group 1 and 80 (14.1%) patients of groups 2 (p = 0.029). The mean (±SD) prostate volume was higher in group 2 compared with group 1 (34.1(±8.4) ml vs 54.1(±9.9) ml, p
