Allogeneic haematopoietic cell transplantation for multiplemyelomanThe allogeneic transplant has the advantage over the autologous transplantnThe graft does not contain tumor cells and the potential for a graft versus myeloma (GvM) effectBone marrow transplantation in three patients with multiple myeloma Gahrton G, Ringdn O, Lnnqvist B, Lindquist R, Ljungman P.Acta Med Scand 1986;219(5):523-7.瑞典卡罗林斯卡医学院瑞典卡罗林斯卡医学院 1983Myeloablative conditioning nThree patients with multiple myeloma received bone marrow grafts from HLA-identical sibling donorsnOne of the patients, with IgA kappa myeloma, refractory to alkeran-prednisone therapy, is well and still without sign of disease 26 months post transplantationn A second patient with Bence-Jones kappa myeloma is well, and skeletal pain and Bence-Jones proteinuria has disappeared 2 months after transplantation.nA third patient with IgG-lambda myeloma died of effusive pericarditis shortly after transplantation. Acta Med Scand 1986;219(5):523-7Conclusion n Bone marrow transplantation may be indicated in a selective group of patients with multiple myelomaActa Med Scand 1986;219(5):523-7n Out of 690 allogenetic

transplantationnduring the years 1983 to 1994n189 myeloma patients who underwent allo-BMT with an HLA-identical sibling donor were compared retrospectively with an equal number of patients who received a single autologous bone marrow or blood stem cell graftnAnd the ASCT patients were transplanted from 1986 to 1994nconclusionnThe overall survival was significantly better for ASCT than for allo-BMT, with a median survival of 34 months and 18 months, respectively (P = .001), uThe main reason for the poorer survival in allo-BMT patients was higher TRM (41% v 13% for ASCT, P = .0001), which was not compensated for by a lower rate of relapse and progressionn conclusionnHowever, in patients alive at 1 year posttransplant, there was a trend for better long-term survival (P = .O9) and significantly better progression-free survival (P = .02) for allo-BMT as compared with ASCTnWe conclude that the median survival is superior for ASCTnHowever, allo-BMT has a lower relapse rate, which results in a similar long-term outcome for both approaches, but a longer follow-up is needed to assess the final outcome Reduced-intensity conditioning allogeneic transplantationnThe Allo-RIC was introduced in an attempt to decrease the transplant-related toxicity while retaining the beneficial GvM effectn1998 begin clinical studyn 19982003nWe report the outcome of 229 patientswho received an allograft for myelomawith reduced-intensity conditioning (RIC)regimens from 33 centers within the EBMT.nWith a median follow-up of 28 months, 115 patients are alive(range, 1-53 months)nThe estimated overall survival at 3 years is 40.6% (CI, 33%-49%) nThe treatment-related mortalities at day 100, 1 year,and 2 years were 10%, 22%, and 26%, respectively.nThe cumulative probability of the progression-free survival was 21.3% (CI, 15%-29%) at 3yearsnConclusionnWhile RIC is feasible, heavily pretreated patients and patients with progressive disease do not benefit RIC vs MACnData were available on a total of 516 patients from 103 centers: 320 patients with RIC and 196 with MAC.nbetween January 1, 1998, to December 31, 2002nThe median follow-up was 28 monthsnconclusionn RIC was associated with a reduction in TRM but this was offset by an increase in relapse risk nthe conditioning intensity did not impact on overall survival or retain significance for PFSnThese data suggest that there is a continuing need to investigate dose intensity in the conditioning for myeloma allografts.Tandem autologous/Allo-RIC transplantationn Autologous hematopoietic cell transplantation(HCT) followed by nonmyeloablative allogeneic HCT (auto/alloHCT) provides cytoreduction and graft-versus-myeloma effects. 弗雷德哈钦森癌症研究中心弗雷德哈钦森癌症研究中心n Patient inclusion criteria for this analysis were ustage

Double autologous Versus tandem auto/Allo-RIC transplantation圣乔凡尼巴蒂斯塔大学医院,都灵,意大利圣乔凡尼巴蒂斯塔大学医院,都灵,意大利 n Methodsn All patients were initially treated with VAD followed by melphalan and autologous stem-cell rescuenPatients with an HLA-identical sibling then received nonmyeloablative total-body irradiation and stem cells from the sibling. Patientsnwithout an HLA-identical sibling received two consecutive myeloablative doses of melphalan, each of which was followed by autologous stem-cell rescue.nThe primary end points were overall survival and event-free survival.n ConclusionsnAmong patients with newly diagnosed myeloma, survival in recipients of a hematopoietic stem-cell autograft followed by a stem-cell allograft from an HLA-identical sibling is superior to that in recipients of tandem stem-cell autografts.n UNSOLVED QUESTIONS IN ALLOGENEIC TRANSPLANTATIONuWhich is the best allogeneic transplantation approach?uWho are the patients most likely to benefit from Allo-RIC?uHow to improve the results of Allo-RIC?
