Autologous peripheral blood hemopoietic stem cell transplantation in combination with bortezomib and high-dose melphalan for multiple myeloma in 3 cases / 中国组织工程研究

ABSTRACT

BACKGROUND:Autologous peripheral blood hemopoietic stem cell transplantation(HSCT)in combination with high-dose chemotherapy significantly improves complete remission and survival rate of multiple myeloma patients.However,the relapse rate is high.Bortezomib is 26S proteasomes inhibitor,and effective on the primary treatment of multiple myeloma.OBJECTIVE:To evaluate the curative effect of HSCT in combination with bortezomib and high dose-melphalan for multiple myeloma.METHODS:A retrospective analysis of 3 patients with a stage-ITT multiple myeloma admitted to Department of Hematology,Affiliated Hospital of Guiyang Medical College from October 2006 to May 2007,was conducted.Chemotherapy and granulocyte colony-stimulating factor were used to mobilize autologous peripheral blood hemopoietic stem cells.All patients were pretreated with 200 mg/m2 melphalan via intravenous drip 3 days before transplantation,followed by HSCT 48 hours after drug termination.RESULTS AND CONCLUSION:All patients obtained prompt and sustained hematopoietic reconstitution,and bone marrow depression restored 30 days following HSCT.Case 1 and 2 obtained complete remission,and case 3 obtained partial remission.Results show that HSCT in combination with bortezomib and high-dose melphalan is a safe and feasible treatment on multiple myeloma.The patients have good tolerance to pretreatment.
