OBJECTIVE: To explore the efficacy of tyrosine kinase inhibitor (TKI) combined with decitabine, homoharringtonine, and interferon regimen as maintenance therapy for blast phase chronic myeloid leukemia (CML-BP).
METHODS: The clinical data of CML-BP patients who received the first major hematological response after induction therapy at The Affiliated Cancer Hospital of Zhengzhou University from June 2015 to December 2021 were analyzed retrospectively. The event-free survival, duration of remission, and overall survival of patients in TKI combined with decitabine, homoharringtonine, interferon group(n=18) and TKI combined with conventional chemotherapy group(n=10) were compared by log-rank test.
RESULTS: A total of 28 patients were included, with a median age of 46 (24-58) years old. Kaplan-Meier survival analysis showed that patients in TKI combined with decitabine, homoharringtonine, interferon group had longer event-free survival (7.4 vs 4.3 months, P=0.043, HR＝0.44, 95% CI: 0.17-1.14), duration of overall remission (16.1 vs 6.6 months, P=0.005, HR＝0.32, 95% CI: 0.11-0.89), overall survival (34.3 vs 13.5 months, P=0.006, HR＝0.29, 95% CI: 0.10-0.82) compared with patients in TKI combined with conventional chemotherapy group.
CONCLUSION: The TKI combined with decitabine, homoharringtonine and interferon regimen can significantly prolong the survival of CML-BP patients who obtained the major hematological response compared with TKI combined with conventional chemotherapy regimen.
