ABSTRACT
Objective To explore the effective treatment with regimen of remission induction for relapsed/refractory precursor lymphocytic leukemia/lymphoma patients. Methods 6 patients with relapsed/refractory precursor lymphocytic leukemia/lymphoma including 2 acute lymphocytic leukemia, 4 lymphoblast lymphoma and 1 hybrid acute leukemia were treated by combination of CAG regimen with L-asparaginase (L-Asp) and prednisone (PDN). Results All patients responded to the regimen, in which 6/7 (85.7 %)patients achieved complete remission and 1/7 (14.3 %) patient achieved partial remission after one course.Light adverse events coursed by the regimen could be tolerated. Conclusion The regimen consisting of CAG, PDN and L-Asp is worth exploring for relapsed/refractory precursor lymphocytic leukemia/lymphoma.
