Molecular devolution in chronic myelomonocytic leukemia during treatment with decitabine/cedazuridine: A case report
摘要
Oral decitabine/cedazuridine has been studied in chronic myelomonocytic leukemia (CMML) recently but the molecular changes during this treatment have not been reported so far. We report a CMML patient who was treated with oral decitabine/cedazuridine and showed a stepwise loss of KRAS mutation and trisomy 8 while the TET2 mutated clone gradually increased eventually resulting in clonal hematopoiesis. This case report highlights the disease modifying potential of this treatment in single CMML patients.
