Abstract:
Treatments for patients with metastatic or advanced urothelial carcinomas on progression after first line chemotherapy or unfit for cisplatin are currently limited. Atezolizumab (Tecentriq®) is a monoclonal antibody targeting PD-L1. The first of IMVIGOR 210 phase II trial (NCT02951767) investigated atezolizumab as front line treatment among 119 patients with metastatic urothelial cancer unfit for cisplatin. Response rate was 23% and median overall survival 15.9 months. The second cohort (NCT02108652) included 310 patients whose tumors were progressing after first line platinum-based chemotherapy. Response rate was 15% and median overall survival 7.9 months. Among patients with high PD-L1 expression on infiltrating immune cells (ICs), response rate was 26% and median overall survival 11 months. Atezolizumab was well-tolerated in both cohorts with 66% of treatment-related toxicities including 12% (cohort 1) and 7% (cohort 2) of grade 3-4 adverse events. These results led to an approval by the FDA in United States and the EMA in Europe. In France, atezolizumab was available through an early access agreement by the French National Agency for Medicines and Health Products (ANSM) for patients with metastatic or advanced urothelial carcinomas on progression after first line chemotherapy or unfit for cisplatin. So far, its avaibility in France within the EMA approval is pending its pricing.

01:13Introduction to Urinary System
The kidneys are bean-shaped organs located in the retroperitoneal space, on either side of the vertebral column, between the T12 and L3 vertebrae. They are partially protected by the rib cage and surrounded by perirenal fat, which provides cushioning. They are responsible for urine formation and play critical roles in regulating blood pressure, electrolyte levels, and hormone production. The ureters...
