Abstract:
Objective:To explore the effect of combination regimen of interferon alpha-1b, interleukin-2 and thalidomide (ITI regimen) on minimal residual disease (MRD) in patients with acute myeloid leukemia (AML) who were in hematologic remission but MRD-positive.
Methods:Eighteen patients (17 from Tumor Hospital of Zhengzhou University and 1 from the First People's Hospital of Pingdingshan City) with AML admitted from July 2016 to June 2018, who were in hematologic remission but MRD-positive were treated with different doses of ITI regimen, and the MRD levels were monitored.
Results:Among 18 patients who received a conventional dose of ITI regimen for 1 to 2 months, 7 patients had undetectable MRD, 3 had significant decrease in MRD levels, 3 had elevated MRD level and had hematologic recurrence. Three patients with elevated MRD level received a higher dose of ITI regimen, 2 of them turned to MRD negative and the other 1 patient had decreased MRD level. The total response rate was 72.2%, and the response rate in patients with MRD > 1.0% was 57.1% (4/7) , and that of patients with MRD < 1.0% was 81.8% (9/11) , respectively.
Conclusion:The ITI regimen can reduce the MRD level of patient with AML who are in hematologic remission but MRD-positive. The therapeutic effect could be improved by a higher dose administration of ITI regimen, and therapeutic effect may be negatively correlated with MRD level before treatment.
