Acute myeloid leukemia combined with myeloid sarcoma: report of three cases and review of literature / 白血病·淋巴瘤

ABSTRACT

Objective@#To analyze the diagnosis and treatment of acute myeloid leukemia (AML) complicated with myeloid sarcoma (MS).@*Methods@#The clinical features, diagnosis and therapy of 3 AML who were treated with routine regimen induction and consolidation therapy in Shanghai Beizhan Hospital and showed MS during the marrow remission stage were retrospectively analyzed.@*Results@#Three female patients included 2 cases of CBFβ-MYH11 positive and 1 case of AML1-ETO positive. One patient occurred in the first complete remission(CR1) and 2 patients occurred in CR2. The involved sites included brain, vagina, and breast respectively. Three patients all received short efficacy after chemotherapy, including 1 patient in bone marrow remission stage, 1 patient died of after bone marrow relapse and 1 patient without follow-up.@*Conclusions@#For AML patients in remission with extramedullary lesions, pathological examination is warranted to confirm the diagnosis of the disease. Systemic chemotherapy is still the main treatment for MS. Central nervous system(CNS) leukemia treatment should be performed to the patients with CNS involved. Allogeneic hematopoietic stem cell transplantation may be the best option for the treatment of these patients.
