Abstract

The FMS‑like tyrosine kinase 3‑internal tandem duplication (FLT3‑ITD) gene mutation is present in ~20% of patients with de novo acute myeloid leukemia (AML). Patients with an FLT3‑ITD mutation have a poor prognosis. However, the prognostic function of FLT3‑ITD combined with other cytogenetic abnormalities are not clear. In the present study, a retrospective analysis of 103 newly diagnosed patients with AML was performed. The results revealed that the overall survival (OS) and recurrence‑free survival (RFS) times were significantly longer in patients with an FLT3‑ITD mutation combined with other favorable risk genes, compared with in those patients with a single FLT3‑ITD mutation (P=0.0361 and P=0.0426). Sorafenib combined with chemotherapy significantly improved the overall response rate (ORR) when compared with mono‑chemotherapy (P=0.039), but no significant differences were observed in the OS and RFS. In conclusion, favorable‑risk cytogenetics may improve the clinical outcomes of patients with FLT3‑ITD‑mutated AML, but adverse‑risk cytogenetics may not further worsen the prognosis. Sorafenib combined with chemotherapy may increase the ORR but would not result in a longer OS and RFS.
