title: Autologous bone marrow transplantation for metastatic breast cancer.
abstract: Metastatic breast cancer accounts for 18% of cancer deaths among women in the U.S. Conventional combination chemotherapy produces responses in 50% to 80% of women with metastatic breast cancer, but is never curative. A major medical center administered high-dose chemotherapy and autologous bone marrow transplantation to 68 women with metastatic breast cancer between 1983 and 1993. Forty-nine of these women had estrogen receptor-negative tumors, a poor prognostic sign. Eighteen women with estrogen receptor-positive tumors had failed prior hormonal manipulation or had metastatic breast cancer at initial diagnosis. Prior to transplantation, 37 women were in first complete or partial remission, 8 were in their second complete or partial remission, 4 had stable disease, 14 had progressive disease, and 5 were in untreated relapse. Bone marrow transplantation preparatory regimens included high doses of single agents or combination chemotherapy. Among women not in remission before transplantation, 71% entered a partial or complete remission following transplantation. Overall, 29 women (43%) were in complete remission after marrow transplantation. Twelve women (18% overall) remain free of disease between 2 and 73+ months post-ABMT. Those in first complete or partial remission prior to transplant (37 patients) had a higher response rate (86%) and higher complete responses (62%), and 10 (27%) are free of disease. There were nine treatment-related deaths (13%). Forty-seven patients (69%) have died from breast cancer following autologous transplantation. Relapses occurred primarily at sites of previous disease. All relapses have occurred within 22 months of ABMT.
  
  
  CONCLUSIONS
  Autologous bone marrow transplantation for metastatic breast cancer in first complete or partial remission has produced a 27% disease-free survival. This therapy should be considered for selected patients with metastatic breast cancer.
