Abstract

Fourty-six patients (41 evaluable) were treated in second line chemotherapy of metastatic breast cancer (MBC) by an association of mitomycin (M), vinorelbine (V) (M 8 mg/m2 D1, V 25 mg/m2 D1 and DI 8 every 4 weeks). Median age was 58 years (36-78), median performance status 1 (0-3). Thirty-seven per cent of the tumors were estrogen receptors positive and 17% progesterone receptors positive.eventeen patients received an adjuvant chemotherapy and 39 a first line chemotherapy with anthracyclin (A). The median number of metastatic sites was 2 (1-4) and 27 patients (67%) had visceral metastases. Twelve patients were refractory to anthracyclins and 5 resistant. No toxic death nor hemolytic uremic syndrom were observed.even (3,7%) febrile neutropenias happened responsible for 4 hospitalizations. A grade 3 or 4 neutropenia was noted in 34% of the cycles but no other clinic toxicity nor grade 3 or 4 thrombopenia. The rate of objective response (OR) was 37,5% with 2 complete responses (CR) and 13 partial responses (PR).even patients had stable disease and 18 progressed. The rate of hepatic OR was 31%. Five (40%) A-refractory patients responded but no resistant patient. Median OR time was 10 weeks (8-12) and median OR duration was 5 months (3-6). Median survival was 11,5 months. MV association is well tolerated and effective in second line chemotherapy for MBC even with hepatic metastasis and in patients refractory to anthracyclins.
