The 29th Annual Meeting of the Chinese Society of Clinical Oncology (CSCO) was held in Jinan, Shandong Province, from September 16 to 19, 2026. During the meeting, Professor Yongmei Yin of Jiangsu Province Hospital presented updated results from OptiTROP-Breast05, a multicenter Phase II study evaluating first-line sacituzumab tirumotecan (sacituzumab govitecan? No—sacituzumab tirumotecan, SKB264/MK-2870), China's first independently developed TROP2-directed antibody–drug conjugate (ADC), in advanced triple-negative breast cancer (TNBC). The objective response rate (ORR) reached 70.7%, and median overall survival (OS) was 32.8 months. At the opening ceremony on the first day of the CSCO Annual Meeting, the study received the “2026 Innovation Research Award,” reflecting strong recognition from Chinese experts.
