Abstract:
OBJECTIVETo investigate the inductive therapeutic effects of imatinib combined with VP low dose regiment on adult patients with Ph-positive acute lymphoblastic leukemia (Ph(+) ALL).
METHODSFourteen newly diagnosed adult patients with Ph(+) ALL were treated with VP regimen, and imatinib (400 mg/d) was added at the 8(th) day. VP regimen would be stopped when neutropenia lasted for 1 week or complicated with infection, fever, etc. Therapeutic effects were assessed by bone marrow morphology and quantitative analysis of BCR/ABL:ABL at the 28(th) - 33(rd) day. Patients could be treated with imatinib combined with chemotherapy for consolidation and maintenance therapy or were treated with allogeneic hematopoietic stem cell transplantation after complete remission.
RESULTSFourteen cases obtained CR1 after first course of treatment, the median decline of BCR/ABA:ABL was 55.89 (10.25 -180.97) %; during the induction chemotherapy, pulmonary infection occurred in 3 patients, diarrhea in 1 patients, facial edema in 3 patients, however, all these patients were cured after symptomatic treatment, only 1 patient died of relapse after transplantation.
CONCLUSIONIn the period of tyrosine kinase inhibitor (TKI), inductive chemotherapy combined with imatinib and low dose VP can obtaine satisfactory CR rate and decrease the toxicity of the traditional drugs. It is suggested that TKI combined with VP regimen chemotherapy can achieve CR1 and make possible for allo-HSCT, from which patients can achieve the long-term survival.
