Incidence of Pathological Types of Urinary Bladder Tumors Diagnosed at Ain Shams University Hospitals

Abstract

Abstract Background Bladder cancers are the most common genitourinary malignancy in both males and females. They are broadly categorized as urothelial and non-urothelial tumors. The response to treatment and the overall survival among the cases with cancer bladder depend greatly on the pathological type of the tumors. Objective Detection of the incidence of different pathological types of bladder tumors diagnosed at Ain Shams University Hospitals. Patients and Methods This retrospective study was conducted by reviewing the medical records of patients admitted and treated for urinary bladder cancer along five years duration from January 2017 to December 2021. We applied our study on 1000 patients. Results TCC was the most common type among our cases 945 (94.5%) followed by SCC 1.5%, adenocarcinoma 1.0% and others (3.0%). As regard lymph nodes, metastasis and type of treatment, our study revealed that they were negative or couldn't be detected in 90% of cases that proved that the majority of urinary bladder tumors are usually localized with less liability of spread so most of cases (74%) treated by follow up cystoscopy with less need for radical cystectomy or chemo-radiotherapy. However, most of the SCC cases were positive lymph nodes (66.7%) with positive metastasis (66.7%) and required radical cystectomy. Most of tumors were located in posterior and posterolateral (right and left) parts of the urinary bladder. Bladder tumors were more frequent in age group of 57.34 ± 15.08 years with male predominance (86.0%). Conclusion Screening of bladder tumors should be scheduled for high risk cases.
