title: [Allogeneic peripheral stem cell transplantation (PBSCT) for hematological malignancies].
abstract: OBJECTIVE
  To evaluate the efficacy of allo-PBSCT in hematological malignancies.
  
  
  METHODS
  Sixteen patients with hematological malignancies were treated by allo-PBSCT, started from march 1997. Five of them were ALL (CR1 4, CR2 1), 2 ANLL (CR1), 8 CML(CP 5, AP 3), and one NHL(PR). The median age was 33(18-49) years. Conditioning regimen was TBI 9-10 Gy + CTX 120 mg/kg, or TBI 10 Gy + CTX 120 mg/kg + Vp16 500 mg. A combination of cyclosporine and methotrexate was administered to prevent acute GVHD. All donors received G-CSF 5 micrograms.kg-1.d-1 for 5 to 6 days. One or three leukapheresis procedures were performed by CS 3000 plus blood cell separator to collect a median mononuclear cells of 9 x 10(8)/kg recipient weight [range(5.79-13.7) x 10(8)/kg], including a median CD34+ cells 13.9 x 10(6)/kg [range(5.69-49.00) x 10(6)/kg].
  
  
  RESULTS
  All patients were engrafted and hematopoietic reconstitution was rapid: neutrophils achieving 0.5 x 10(9)/L on day 12 (range, 10-15), platelets > 30 x 10(9)/L on day 13 (range, 8-24). More than grade II aGVHD occurred in 3(18.7%), and localized cGVHD in 3 patients. Leukemia relapse occurred in one patients. The median follow-up duration was 13 months. Eleven patients were alive in disease-free situation.
  
  
  CONCLUSIONS
  Allo-PBSCT can rapidly reconstitute hematopoiesis with incidences of aGVHD and cGVHD not more than that in BMT.
