Immune checkpoint inhibitors have rapidly reshaped care for triple-negative breast cancer (TNBC)—but surgical teams increasingly encounter their downstream perioperative consequences. In this episode, we define immunotherapy through the lens of checkpoint biology, review the landmark evidence supporting pembrolizumab in metastatic PD‑L1–positive TNBC (KEYNOTE‑355) and curative-intent stage II–III TNBC (KEYNOTE‑522), and translate immune-related adverse events (irAEs) into practical periop recognition, triage, and timing decisions—especially for endocrine, pulmonary, hepatic, dermatologic, and GI toxicities.
