Acute myeloid leukemia post‑cytotoxic therapy following chemotherapy for thymoma: A case report

The present study reports the case of a patient with acute myeloid leukemia post-cytotoxic therapy (AML-pCT) that developed following chemotherapy for thymoma. A 64-year-old female patient underwent surgical resection for a mediastinal tumor and was diagnosed with stage IVa thymoma. She received chemotherapy, including carboplatin/etoposide, carboplatin/paclitaxel and amrubicin monotherapy. At 56 months following surgery, she developed blastosis and was diagnosed with AML-pCT. As demonstrated herein, although treatment for thymoma is associated with a markedly lower frequency of myeloid neoplasms post-cytotoxic therapy (MN-pCT) than treatment for other malignancies, such as breast carcinoma, it is important to be aware that MN-pCT may occur as a late complication of thymoma treatment.
