Safety and efficacy of perioperative cisplatin/gemcitabine (cis/gem) and durvalumab (durva) for operable muscle-invasive urothelial carcinoma (MIUC): SAKK 06/17.

摘要: 430 Background: The combination of cisplatin-based chemotherapy with immune checkpoint inhibitors is extensively investigated in urothelial carcinoma. Using this combination in the neoadjuvant setting for patients (pts) with MIUC might improve pathological response rate (PaR:< ypT2N0) but carries the risk of increased perioperative morbidity. Methods: SAKK 06/17 is an open-label single arm phase II trial for pts with operable MIUC cT2-T4a cN0-1. Treatment consists of 4 cycles of neoadjuvant cis/gem q3w …
