From January 1976 to January 1985, 210 patients (less than 70 years old) with unilateral inflammatory breast carcinoma M0 were treated, under protocol way, by chemotherapy, hormonotherapy and radiotherapy association. Results of these protocols are compared to those of an historical control group T (60 patients treated from 1973 to 1975 by radiotherapy alone, with castration for pre-menopausal women). From 1976 to 1980, 91 patients (group A) were treated by induction chemotherapy first with adriamycin, vincristine and methotrexate (AVM), loco-regional radiotherapy and maintenance chemotherapy with vincristine, cyclophosphamide and 5 fluorouracil (VCF). From 1980 to 1982, 79 patients (group B) were treated under a similar protocol, but the 3 first sequences were reinforced with the association of five drugs: adriamycin, vincristine, cyclophosphamide, methotrexate, 5 FU (AVCMF). From 1983 to 1985, 40 patients (group C) were treated under the same schedule AVCMF, AVM, VCF, but radiotherapy was delivered on a different schedule to shorten the intervals between the 3, 4, 5 and 6th chemotherapy sequences. All patients form the groups A, B and C had received hormonotherapy: castration for premenopausal patients or on-going menopause, or tamoxifen for post-menopausal patients. Disease-free survival rates at 30 months are respectively 19, 37, 61 and 64% for groups T, A, B and C and for groups T, A and B: 8, 22 and 40% at 5 years, and total survival rates at 5 years: 28, 40 and 55% for these groups. The benefit of chemotherapy in addition to radiotherapy is highly statistically significant. The improvement of these results seems partially linked to the increasing dosage of the induction chemotherapy.
