Objective:To evaluate the effect of hematopoietic stem cell transplantation combined with Chinese herbal medicine in treating malignant hematopathy.Methods: Allo-bone marrow transplantation (allo-BMT) or allo-peripheral blood stem cell transplantation (allo-PBSCT), with conditioning regimen of 60 　Co total body irradiation + Cyclophosphamide (TBI+Cy) or busulfan + cyclophosphamide (Bu+Cy), was used to treat 4 cases of chronic granu locytic leukemia (CGL, 3 of chronic phase and 1 of accelerating phase) and one case of acute non-lymphocytic leukemia (ANLL). And auto-BMT or auto-PBSCT, with conditioning regimen of my leran + cytosino arabinoside +cyclophosphamide (MAC) or MAC+VP16, was used to tr eat 7 cases of hematopathy, including 5 cases of ANLL (3 of CR 1 and 2 of CR 2) and 2 cases of malignant lymphoma (1 of the first occurrence and 1 of relapse). Chinese herbal medicine was given orally to all the 12 patients after transplantation according to TCM Syndrome Differentiation. Results: All patients were successfully engrafted. Within the median follow-up period of 18 (4-70) months, 1 patient (8.3%) died a transplantation-related death, 3 ( 25.0% ) relapsed and 8 (66.7%) survived free of original disease. Conclusion: Auto-BMT or auto-PBSCT in CR 1 stage of acute leukemia could reduce the relapse rate, when there was no matched bone marow donor; allo-BMT or allo-PBSCT in chronic stage could result in long-term disease-free survival of patients; Chinese herbal medicine administration in patients of malignant hematopathy after transplantation might reduce the complications and plays certain rol e in promoting recovery of hematopoietic function.
