Two-way direct sequencing and Gene Mapper version 4.0 software (Fred Hutchinson Cancer Research Center) sequencing were used as confirmatory tests for DNMT3A and NPM1A mutations, respectively.ResultsDNMT3A, FLT3-ITD, and NPM1A gene mutations were detected in 22 (17.9%), 22 (17.9%), and 24 (19.5%) patients, respectively. DNMT3A/FLT3, NPM1A/FLT3, and DNMT3A/NPM1A combined mutant genotypes were detected in 5 (4.1%), 9 (7.3%), and 3 (2.4%) patients, respectively. Two patients (1.6%) had triple mutant genotypes (DNMT3A/FLT3/NPM1A). FLT3 and DNMT3A mutations had a significant negative effect on complete response (CR) rates (P = .016). FLT3-ITD mutation was significantly associated with older age (P = .029), and lower overall survival (OS) rates (P = .046). DNMT3A/FLT3 combined mutant genotypes were significantly associated with a lower OS rate (P = .016). Mutant NPM1/wild type FLT3, wild type DNMT3A/FLT3, and mutant NPM1A/wild type DNMT3A combinations were significantly associated with higher CR rates (P = .006, P = .006, and P = .023, respectively).ConclusionDNMT3A, FLT3-ITD, and NPM1A are frequent mutations in Egyptian AML. FLT3-ITD mutations are frequent in older patients. DNMT3A and FLT3-ITD mutations were associated with an unfavorable prognosis, but the NPM1A mutation has tendency to indicate a good prognosis."xsd:string |
