RESUMO
Objective To observe the efficacy and adverse effects of MRC UKALL Ⅻ/ECOG E2993 regimen in inducing remission of Chinese adults with acute iymphoblastic leukemia(ALL). Methods 11 cases of previously untreated ALL patients were treated with MRC UKALL Ⅻ/ECOG E2993 regimen, then observe the efficacy and adverse effects. Results All of the 11 patients achieved complete rcmission(CR), the CR rate was 100 %. Among the 11 patients,8 patients achieved CR after the first course of chemotherapy. In the 8 patients which could be followed up, 5 patients achieved durative CR, among that the longest survival time was 30 months, and 3 patients had relapses. This regimen has a severe myelosuppression. There was an effect on liver function, mostly in the increase of glutamic-pyruvic transaminase and glutamic-oxaloacetic transaminase.After the symptomatic treatment, liver function could return to normal.
