Bladder cancer in young adults: Disease and treatment characteristics of patients treated at a tertiary cancer center

Abstract

Objectives: The incidence of bladder cancer in the Middle East is increasing. Nevertheless, data on the young population with urothelial carcinoma (UC) of the urinary bladder in this region is scarce. Therefore, we evaluated clinical and tumor characteristics, in addition to treatment details in patients younger than 45 years old. Methodology: We reviewed all patients presenting with UC of the urinary bladder from July 2006 to December 2019. Clinical characteristics including demographics, stage at presentation, and treatment outcomes were extracted. Results: Out of 1272 new cases of bladder cancer, a total of 112 (8.8%) patients were ≤45 years old. Seven patients (6%) had nonurothelial histology and were excluded from the study. The remaining 105 eligible patients with UC had a median age at presentation of 41 years (35-43). Ninety-three patients (88.6%) were males. Tumor stage at presentation: nonmuscle invasive disease (Ta-T1), locally advanced muscle-invasive bladder cancer (MIBC) (T2-3), and metastatic disease were 84.7%, 2.8%, and 12.5%, respectively. All patients with MIBC received neoadjuvant cisplatin-based chemotherapy. Radical cystectomy was performed in 8 (7.6%) cases; three patients with MIBC and five with high-volume non-MIBC. Neobladder reconstruction was done in six patients. A total of 13 patients with metastatic disease (93%) received palliative chemotherapy (gemcitabine/cisplatin), and one (7%) was a candidate for best supportive care only. Conclusion: Bladder cancer is relatively rare in the young population, although the incidence at our region is higher than other reports in the literature. Most patients present with early disease. Early diagnosis and multidisciplinary approach are paramount for the management of these patients.
