WebNPM1, FLT3-ITD, and DNMT3A triple mutations were only found in the relapse group although their co-existence was detected in newly diagnosed, relapsed, and refractory patients. Refractory patients with NPM1 and FLT3-ITD co-mutation experienced shorter OS than the patients with FLT3-ITD mutation alone or WT-NPM1. 80. Web1 nov. 2024 · However, when neither DNMT3A nor NPM1 are mutated, or when only one of them is mutated, the occurrence of an FLT3 ITD mutation does not alter the prognosis. Conversely, when NRAS G12/13 mutations co-occur with DNMT3A and NPM1 mutations, the OS is statistically improved.
