Abstract

The prognosis of patients with relapsed/refractory acute myeloid leukemia (R/R AML) is poor, with a 3‑year overall survival rate of 10%. Patients with translocation (t)(11;19)(q23;p13) have a higher risk of relapse and there is no optimal regimen for these patients. The present study treated two young patients with t(11;19)(q23;p13) AML, who relapsed after one or two cycles of consolidation, with a salvage treatment consisting of sequential cladribine, cytarabine and etoposide (CLAE) and allogeneic hematopoietic stem cell transplantation (allo‑HSCT). Both neutrophil and platelet engraftments were achieved within 15 days, and no severe transplant‑related complications and graft‑versus‑host diseases were observed. Following allo‑HSCT, both patients achieved complete hematologic and cytogenetic remission. Decitabine was used for the prophylaxis of relapse. The two patients remained alive and disease‑free for 100 days following allo‑HSCT. The results presented here suggest that CLAE regimen sequential with allo‑HSCT may be effective in treating patients with R/R AML, with t(11;19)(q23;p13). However, further studies and a larger sample size are required to validate the effectiveness of this treatment regimen.
