RT–Drug Timing Window
Radiobiological rationale for RT–drug interaction
No DNA-level radiosensitization (ADCC/CDC-mediated) (Saviano et al., Nature Reviews Cancer, 2026; Xie et al., Journal of Hematology & Oncology, 2026). Theoretically, there is no mechanistic basis for increased in-field adverse events; the dominant class adverse effect is GI (nausea/vomiting) from the antibody, independent of RT.
