Research Abstract

Although many advanced bladder cancer patients show an initially good tumor response to systemic chemotherapy, most of them develop recurrences and eventually die from the disease. This phenomenon is attributable to the re-growth of bladder cancer-initiating cells (BCICs) that have survived chemotherapy. In this study, the authors have isolated BCICs, analyzed their chemo-sensitivity and investigated whether heat-shock protein 90 (Hsp90) inhibitors potentiate the chemo-cytotoxicity on BCICs.
