Clinical Outcomes of Patients with Histologic Variants of Urothelial Cancer Treated with Trimodality Bladder-sparing Therapy

The response of histologic variants of bladder cancer to bladder-sparing chemoradiation is largely unknown. We compared the outcomes of histologic variants of urothelial cancer to pure urothelial cancer in a large series of patients from a single institution. We found that variant histology does not significantly influence outcomes.
