Retrospective analysis of the results of high-dose chemotherapy with the support of autologous blood stem cells in patients with multiple myeloma. The experience of a single centre.
Despite new medical products introduced in multiple myeloma therapy, autologous stem cell transplant (ASCT) remains a standard procedure in younger patients with symptomatic disease. We analyzed a group of 190 patients who underwent ASCT at our clinic for multiple myeloma as primary therapy in years 1995-2008. The total number of transplants performed in this group was 291. 110 patients underwent one ASCT, 59 patients had double transplant, out of which 51 patients underwent tandem transplant, 21 patients underwent triple ASCT, out of which 15 patients were transplanted front-line throughout a clinical trial and 6 patients underwent follow-up transplants due to disease progression. The assessment of the best therapeutic effect of ASCT showed the total rates of patients with complete remission--22%, very good partial remission (VGPR)--8%, partial remission--63%, stabilized disease--6% and progression--1%. The transplant related mortality (TRM) was 4.1%. With the median follow-up of surviving patients 2.6 years, the median progression-free survival (PFS) and overall survival (OS) were 21 and 54 months, respectively; the likelihood of a 7-year overall survival was 28%. Comparing tandem versus single transplants, there was a significant increase in the median PFS (25.8 versus 20.8 months, respectively); however, there was no difference in overall survivals. The IVE mobilization regimen was found to be more efficacious for PBPC collection than high-dosed cyclophosphamide.
