title: [Small cell lung cancer with acute monocytic leukemia after combined chemotherapy including etoposide].
abstract: Small cell lung cancer (stage IIIB) developed in a 61-year-old woman. She was treated with chemotherapy in which the cumulative dose of carboplatin was 662 mg/m2 and that of etoposide was 2,000 mg/ m2, and with concurrent irradiation in which the total dose of X-rays was 44.8 Gy. The response to chemotherapy and irradiation was very good. Radiation pneumonitis developed after discharge, but it resolved after steroid therapy. Nine months after the diagnosis of lung cancer the patient was readmitted because of bleeding and leukocytosis. Acute monocytic leukemia (M5a) was diagnosed after examination of a bone-marrow aspirate. The patient was treated with chemotherapy, but she died of severe bone-marrow suppression and multiple organ failure 3 months after the diagnosis of acute monocytic leukemia. Although chromosome analysis could not be done, we strongly suspect that this leukemia was induced by etoposide, because of the clinical course.
