Abstract
Background: Squamous cell carcinoma is the most common type in Egyptian bilharzial bladder. However, there is a proven changing pattern of Schistosoma-associated bladder cancer (SA-BC) that needs to be investigated. Objective: To assess the patterns (age, incidence, and histopathological types) of SA-BC in Sohag, Egypt. Material and Methods: This descriptive retrospective study included 152 patients histologically confirmed urinary BC diagnosed at the Pathology Department of Sohag University Hospital during 4 years, from January 2019 to December 2022. Data including age, sex, residence, and histopathological type were retrieved from the records of Pathology Department. Results: Patients’ age ranged from 35-79 years with a mean of 61.2±9.1 years, and male to female ratio was 4.6:1. Transitional cell carcinoma (TCC) was the most common histological type (80.9%), followed by squamous cell carcinoma (SCC) (12.5%), and TCC with squamous differentiation (6.6%). Schistosoma eggs were histologically confirmed in 39.5% of cancer cases; 76.7% were TCC, 21.7% were SCC and only 1.6% was TCC with squamous differentiation. All SA-BC were male with mean age of 59.8±7.5. At the time of diagnosis, 96.7% of SA-BC cases were bladder muscle invasive and 91.7% were of high-grade nature not significantly different from cases with non-Schistosome associated BC (NSA-BC). Conclusion: The histopathological patterns of SA-BC have changed in Egypt over the past decade and most cases were associated with TCC.
