RESUMO
High dose chemotherapy with autologous bone marrow transplantation has been proposed in metastatic and inflammatory breast cancer. Data in the literature reported an improvement of the quality and of the rate of response. However, the impact on survival remains to be demonstrated. Since 1985, a pilot study in inflammatory and directly metastatic breast cancer has been started in order to determine the impact of high dose chemo-radiotherapy. Patients were treated with an induction regimen consisting of cyclophosphamide 1,200 mg/m2 and 4'epi-adriamycin 75 mg/m2 every 15 days x 4. Mastectomy was performed associated for patients younger than 50 years with bone marrow collection and cryoconservation. In this group, late intensification with cyclophosphamide 2.2 g/m2 day 1 and 2, TBI and autologous bone marrow transplantation was performed. Fourteen patients have been treated: 9 inflammatory breast cancers T4 b N1 M0, 5 metastatic cancers at presentation including 3 with inflammatory breast cancer T4 b N1 M1 and 2 metastatic T2 N1 M1. Relapses had occurred in 7 patients, of them 4 were metastatic. Five patients died from their disease, and one from CMV interstitial pneumonitis. Six patients are alive free of disease but only one was metastatic. On this limited number of patients, survival of metastatic breast cancers does not seem to benefit from this regimen.
