Analysis on clinical characteristics of 10 patients with granulocytic sarcoma / 白血病·淋巴瘤

ABSTRACT

Objective To explore the clinical characteristics,diagnosis,therapy and prognostic features of granulocytic sarcoma (GS).Methods Retrospective analysis was used to analyse 10 cases who were diagnosed with GS.Results Five patients were diagnosed with primary GS.GS was accompanied by APL in one case,CML in 3 cases and MDS in one case.Patients were treated with resection and chemotherapy,or imatinib treatment.Follow-up data were available from 9 patients,with 2 patients being still alive.The survival of one patient who received high-dose cytarabine chemotherapy was 66 months.The other 7patients died of tumor-related diseases,and their survival ranged from 4 to 17 months.Conclusion GS is a rarely diagnosed disease.A correct diagnosis of GS depends on detailed morphological examination and immunohistochemical study.The clinical outcome of patients is poor,and AML-type chemotherapy is the proper treatment for GS.High-intensity chemotherapy and hematopoietic stem cell transplantation might improve long-term survival.
