Abstract:
Objective:To compare the efficacy and safety of azacitidine alone or combined with half-course CAG (arorubicin + cytarabine + granulocyte colony stimulating factor) regimen and azacitidine combined with full-course CAG regimen in treatment of patients with acute myeloid leukemia (AML) or myelodysplastic syndromes (MDS).Methods:The clinical data of 51 patients with AML and MDS admitted to Datong Fifth People's Hospital from September 2019 to March 2022 were retrospectively analyzed. Among them, 17 patients received azacitidine alone 7-day regimen, 17 patients received azacitidine combined with half-course CAG regimen and 17 patients received azacitidine combined with full-course CAG regimen. The remission rate, adverse reaction rate and supportive treatment were compared among the three groups.Results:The objective remission rate (ORR) was 58.8% (10/17), 64.7% (11/17) and 70.6% (12/17) in azacitidine alone group, azacitidine combined with half course CAG group, and azacitidine combined with full course CAG group, respectively, and the difference was not statistically significant among the above groups ( P = 0.773). The main adverse reaction after treatment with azacitidine was bone marrow suppression,and 32 patients had grade 3-4 hematological side effects. The average time of agranulocytopenia was (15±5) d, 23 patients had infection and 11 cases had hemorrhage. There were no significant differences of the three groups in the hemorrhage incidence, the infection, incidence, agranulocytosis time, the amount of red blood cell infusion and the amount of platelet infusion (all P > 0.05). Except 1 patient died of acute left ventricular dysfunction after chemotherapy in the first cycle and 1 patient died of cerebral hemorrhage after chemotherapy in the third cycle, all the patients successfully completed the chemotherapy after active symptomatic support treatment and safely passed the bone marrow suppression period. Conclusions:Azacitidine alone, azacitidine combined with half-course CAG, azacitidine combined with full-course CAG regimens in the treatment of AML/MDS all show good curative effects, and their adverse reactions are similar to supportive treatment. Azacitidine combined with full-course CAG regimen has a relatively high effective rate.
