Metastatic bladder cancer has poor overall survival. Though systemic therapies have shown to improve overall survival, real-world studies have shown that more than half of the patients do not receive any systemic therapy, while only around 15-20% receive second-line therapy. Even in patients receiving systemic therapies a disproportionately higher use of carboplatin is observed in the first line despite proven superior effectiveness of cisplatin. Reasons for these observations include moderate effectiveness and relatively toxicity of platinum-based chemotherapy regimens, concerns with performance status and co-morbidities in this predominantly older patient population, communications barriers, lack of social support, and access to affordable healthcare. Herein we discuss potential ways to overcome these challenges which include (1) preventing/delaying metastatic disease by maximizing the receipt of neoadjuvant cisplatin-based therapy, and development of better tolerated and more effective neoadjuvant and adjuvant therapies, (2) use of avelumab maintenance therapy after 4-6 cycles of platinum-based chemotherapy to overcome attrition of patients from first to second-line therapy, (3) advancing effective and well-tolerated systemic therapies such as enfortumab vedotin, and erdafitinib to the first-line metastatic setting or even to the localized setting, (4) further development of effective and well-tolerated therapies like sacituzumab govitecan, a novel antibody-drug conjugate and (5) improving affordability and accessibility to systemic therapy agents.
