To the Editor:Chronic myelomonocytic leukemia(CMML)is characterized by both myelodysplastic syndromes(MDS)and myeloproliferative neoplasms(MPNs).[1]The rare incidence of CMML leads to the difficulty to establish the standard criteria of diagnosis and specific treatment paradigms,and the accurate prognostic scores are required for appropriate treatment paradigms.
