Notas

Trastuzumab carries HBV reactivation risk (FDA boxed warning class effect for chemoimmunotherapy in HBV-endemic regions). Larotrectinib / entrectinib (CYP3A4 substrates) require ART coordination — avoid ritonavir-boosted PIs. Bicalutamide / LHRH analogs (AR+ SDC) are generally low-risk for HBV reactivation but standard pre-treatment screening still applies. Active TB: complete anti-TB before head-and- neck RT given mucositis + neutropenia overlap. HBsAg+: entecavir / tenofovir prophylaxis. HIV+: PCP prophylaxis if on cytotoxic combination chemotherapy.
