We report a case of far advanced breast cancer showing an excellent response to chemo-endocrine therapy. A 40-year-old female with a huge ulcerated tumor on her left anterior chest visited our hospital. Distant metastases were found in the lymph nodes, liver and bone. Therefore, endocrine therapy (toremifene and medroxyprogesterone acetate) and chemotherapy (cyclophosphamide, Therarubicin and 5-fluorouracil) were started as a combination treatment. As a result, the main tumor and metastatic lesion were remarkably reduced, and extended mastectomy with resection of right axillary lymph nodes was performed. Histologically, cancer cells in the primary lesion mostly disappeared, and only one lymph node in the left axillary lesion showed metastasis. No recurrence was found for 16 months after the surgical treatment. The combined therapy in the present case was extremely effective.
