Abstract:
Objective:To investigate the clinical efficacy and safety of demethylating drugs decitabine and azacitidine in treatment of myelodysplastic syndromes (MDS).Methods:The clinical data of 15 patients initially diagnosed with MDS in Fujian Provincial Hospital from May 2010 to May 2020 were retrospectively analyzed; 10 patients were treated with decitabine (10-30 mg·m -2·d -1, 3-5 d consecutively) and 5 patients were treated with azacitidine (75 mg·m -2·d -1 for 7 d consecutively). Gene mutation, risk stratification, efficacy and adverse reactions were observed. Results:Among 15 patients, 9 cases were males and 6 cases were females, with a median age of 64 years (51-84 years). The median follow-up time was 18 months (4-62 months). There were 3 cases in high-risk group, 10 cases in medium-risk group and 2 cases in low-risk group. SF3B1, TET2 and STAG2 mutations were more common in patients with low to moderate risk; DNMT3A, EZH2, U2AF1, RUNX1 and TP53 mutations were more common in patients with high-risk. All patients were evaluated for efficacy after 2-3 courses of treatment, and the total effective rate was 66.7% (10/15). Among them, 1 case (6.7%) achieved complete remission, 1 case (6.7%) achieved bone marrow complete remission (mCR), 2 cases (13.3%) achieved partial remission, and 6 cases (40%) achieved hematological improvement. During the treatment, 9 cases had grade 3-4 hematological toxicity and 6 cases had grade 3-4 infection. There was no grade 3-4 bleeding, nausea, vomiting and liver function damage. During the follow-up to May 2020, 9 patients survived and 6 patients died.Conclusions:Demethylating drugs decitabine and azacitidine have high rates of complete remission and partial remission and a low rate of adverse drug reactions in MDS patients.
