Immune‐mediated thrombocytopenia induced with durvalumab after chemoradiotherapy in a non‐small cell lung cancer patient: A case report

We describe a case of a 60‐year‐old man with a prolonged thrombocytopenia during a durvalumab maintenance therapy after chemoradiotherapy for locally advanced non‐small cell lung carcinoma. Bone marrow specimen was normoplastic with the marked megakaryocyte depletion, which was assumed to be an acquired amegakaryocytic thrombocytopenic purpura. Although hematological disorders as immune‐related adverse events (irAE) are rare, we should pay more attention to hematological disorders with durvalumab especially after concurrent chemoradiotherapy.
