ABSTRACT
This study was aimed to evaluate the therapeutic efficacy of bortezomib combined with autologous peripheral blood hematopoietic stem cell transplantation (autoPBSCT) for patients with multiple myeloma (MM). 5 patients underwent autologous hematopoietic stem cell transplantation. Bortezomib treatment was supplied for patients before autoPBSCT and in the conditioning of transplantation, it was also used in maintaining treatment. Patients with transplantation adopted bortezomib plus melphalan conditioning regimen. The number of infused MNC and number of CD34(+) cells were 4.06×10(8) (4.09×10(8) - 4.37×10(8))/kg and 3.98×10(6) (2.49×10(6) - 8.2×10(6))/kg respectively. The results showed that hematopoiesis was reconstituted in 5 patients, with a neutrophil cell count more than 0.5×10(9)/L at day 14 (13 - 25 days) after transplantation and platelet count more than 50×10(9)/L at day 28 (21 - 41 days) after transplantation. Transplantation-associated death was not observed. 5 patients were disease-free survival. In conclusion, treatment of bortezomib combined with autologous peripheral hematopoietic stem cell transplantation is an effective method for patients with multiple myeloma. Use of bortezomib after transplantation might still be favourable to MM patients, for survival prolongation and life quality improvement.
