Abstract:

Urothelial Carcinoma (UC) is the second most common malignancy of the genitourinary system and is the sixth most common cancer in the USA. Over a decade prior to 2016, the standard of care for early disease consisted of transuretheral resection of the bladder tumor with or without intravesicular chemotherapy or immunotherapy. Systemic chemotherapies such as gemcitabine and cisplatin combinations or dose-dense methotrexate, vinblastine, doxorubicin, cisplatin were reserved for recurrent, muscle-invasive, advanced or metastatic disease. Novel treatment approaches for UC have significantly impacted the management of patients. In 2016–2017, five immune checkpoint inhibitors marked a new paradigm in the treatment of UC for patients with advanced or metastatic disease or who are unable to tolerate platinum-based chemotherapy. Most recently, the U.S. Food and Drug Administration set restrictions on two commonly utilized checkpoint inhibitors, atezolizumab and pembrolizumab, in the first-line setting in patients with UC due to decreased survival associated with low expression of the protein programmed death ligand 1. Furthermore, Breakthrough Therapy Designations have been granted for enfortumab vedotin and erdafitinib for patients following platinum-based chemotherapy and those with fibroblast growth factor receptor mutated UC, respectively. Additional updates include dose-dense gemcitabine and cisplatin for muscle-invasive bladder cancer and preoperative checkpoint blockade. This article will review the available data on updates in the treatment of UC and future direction of therapies
