Abstract
BACKGROUND AND OBJECTIVES
Squamous cell carcinoma of the bladder (SCCB) is a rare disease composing 2%-5% of all bladder cancers with no consensus regarding treatment. The present study aims to analyze the outcomes of established treatments, namely chemotherapy, radiation, and surgery, to guide clinical decision-making for patients with non-schistosomal SCCB.
METHODS
Patients with bladder SCC diagnosed between 2000 and 2018 were reviewed utilizing data from the Surveillance, Epidemiology, and End Results Registry (SEER) program.
RESULTS
A total of 5653 patients with SCCB were identified; median survival was 13 months and was significantly decreased in patients treated with chemotherapy or radiation (median survival of 9 or 12 months, respectively). Patients treated with both surgery and radiotherapy saw a decreased 5 year overall survival (OS) of 14%, compared to 35% for those treated with surgery alone (p < 0.01). Furthermore, patients treated with surgery, chemotherapy, and radiotherapy saw a decreased 5 year OS of 20%, compared with 25% for those that received surgery and chemotherapy only (p < 0.01). Finally, surgical intervention provided an increased 5 year OS for patients with locoregional disease only; those with distant disease saw no increase in 5 year OS (p < 0.01).
CONCLUSIONS
Based on this study's analysis, radical surgery may be the most effective treatment for this disease.
