Reduced mortality following bone marrow transplantation for breast cancer with the addition of peripheral blood progenitor cells is due to a marked reduction in veno-occlusive disease of the liver.
Clinical trials involving breast cancer in the Duke University Bone Marrow Transplant Program were evaluated to assess the association between type of hematopoietic support and treatment-related morbidity/mortality. Case histories of patients treated with high-dose chemotherapy and hematopoietic rescue on three separate protocols between 1986 and 1994 were reviewed. This included 307 patients with stage IV disease and 85 patients with high-risk (10 or more positive axillary lymph nodes) stage II or III disease. One hundred and twenty-eight of these patients were rescued with autologous bone marrow (BM) alone and 264 additionally received autologous peripheral blood progenitor cells (PBPC). The 100 day transplant-related mortality rate in those patients who received BM alone was 20.3%, with an overall mortality rate due to the high-dose chemotherapy procedure of 24.2%. The PBPC-treated group experienced a 100 day transplant-related mortality of only 6.1% and an overall trans-plant- related mortality of 10.2%. Sixteen of 31 deaths were attributed to veno-occlusive disease (VOD) in the group that received BM alone compared to only one VOD-related death in the PBPC group. These data demonstrate a marked improvement in transplant-related mortality which is related to the use of PBPC. This effect has been almost entirely due to a reduction in mortality from hepatic veno-occlusive disease.
