title: Phase II trial of mitoxantrone, doxifluridine and medroxyprogesterone acetate as second-line treatment for anthracycline-resistant metastatic breast cancer.
abstract: Sixteen patients with anthracycline resistant metastatic breast cancer were treated with a combination of mitoxantrone (MIT), doxifuridine (5'-DFUR) and medroxyprogesterone acetate (MPA). The median dose of anthracyclines was 360 mg (range 20-540 mg). Eligible patients received 7.0 mg/m2 of MIT every four weeks 600 mg of 5'DFUR were given orally every day. Eight (50.0%) out of 16 patients showed partial response. Six (54.5%) out of 11 bone lesions, 4 (80.0%) out of 5 lung lesions and 1 (20.0%) out of 5 soft tissue lesions responded to this treatment. The median response duration was 26 weeks (range 4-52). Hematological and gastrointestinal toxicity were tolerable. Alopecia was not observed. Tachycardia was noted in patients receiving more than 80 mg of MIT; however, digitalis controlled the symptom. The combined treatment with MIT is useful for anthracycline-resistant metastatic breast cancer.
