Treatment of lung adenocarcinoma with chemotherapy helps mitigate chronic myeloid leukaemia progression: A case report

Treatment outcomes for inoperable advanced non-small cell lung cancer have improved in recent years. However, information on coexisting haematological tumours is lacking. The present patient was a 65-year-old woman with stage IVA lung adenocarcinoma. The patient was administered a combination of platinum therapy and immune checkpoint inhibitors. The patient was subsequently diagnosed with chronic myeloid leukaemia (CML) following leukocytosis. Carboplatin and pemetrexed combination therapy resulted in shrinkage of lung cancer. Improvements in peripheral blood leukocyte counts and bone marrow findings were observed. These results suggested that the treatment of lung cancer may control the course of CML.
