UROTHELIAL BLADDER CANCER IN YOUNG PATIENTS UNDER 40 YEARS OLD

Bladder cancer is the 2nd urological cancer, most known in people over 50 years old. We are witnessing increased number ofcases in subjects under 40 years of age, mostly due to several factors. The purpose of our study is to study the pathologic and clinical features of urothelial tumors of the urinary bladder in young patients and to understand the particularity of this entity.Retrospective, descriptive study, on 17 patients, treated at two centers, the urology department of the University Hospital of Souss-Massa (Center A) and Urology department ofUniversity Hospital Ibn Sina in Rabat (Center B).From March 1, 2019 to March 1, 2022.This study concerns 17 patients hospitalized in center A and B with an average age of 35 years, sharing the same risk factors. the pathology was revealed by hematuria. our patients benefited from an initial TUR-V resection, the follow-up was then based on the results of anatomopathology.These tumors were preferentiallylocalized on the lateral face of the bladder, and retrotrigone with an average size of 3 cm in both centers. The most common histologic type wasurothelial carcinomapTa Low Grade in both centers. Bladder tumors in young people are unusual, favored by the presence of risk factors. However, these factorscannot be incriminated due to the short exposure time. Superficial bladder tumors seem to have a good prognosis with little recurrenceunlike infiltrating tumors.
