Acute myeloid leukemia with a ZMYND11 :: MBTD1 fusion gene following chemotherapy and radiotherapy for breast cancer: A case report.

The t(10;17)(p15;q21) translocation is a very rare recurrent cytogenetic aberration, and produced ZMYND11::MBTD1 fusion gene. To date, nine cases of acute leukemia with the t(10;17)(p15;q21) translocation have been reported, but the case of AML with ZMYND11::MBTD1 after chemotherapy and radiotherapy have not been reported. Epirubicin-based chemotherapy or radiotherapy for breast cancer increases the risk of developing secondary leukemia. We report a case of AML with the ZMYND11::MBTD1 fusion gene that developed after epirubicin-based chemotherapy and radiotherapy for breast cancer. previous chemotherapy and radiotherapy may be associated with poor prognosis of AML with ZMYND11/MBTD1 .
