Experts discuss the use of sacituzumab govitecan and trastuzumab deruxtecan in breast cancer treatment, focusing on safety profiles, supportive care, and therapeutic sequencing. They highlight the importance of G-CSF use, the modest overall survival improvement with sacituzumab, and the better tolerability of trastuzumab deruxtecan. The discussion also covers the management of treatment-related toxicities, particularly neutropenia and diarrhea, and the need for early intervention with steroids to mitigate adverse effects.
