[A case of breast cancer with multiple metastases to the lung and bone responding well to cisplatin and vindesine].

A case of recurrent breast cancer with metastases to the lung and bone responding well to cisplatin and vindesine in a 45-year-old woman was reported. She had a radical mastectomy for the right breast cancer (pT2N0M0) at 28 years old. She was well until March 1985, when right iliac bone pain appeared. Osteolytic changes were noted on her pelvic roentgenogram. A biopsy obtained from the right iliac bone revealed metastatic adenocarcinoma. She was admitted to our hospital in December 1985 because of chest pain and swelling of the left axillary lymph nodes. Lymph nodes also showed metastatic adenocarcinoma with positive estrogen receptor. Her chest roentgenogram demonstrated a coin lesion in the left hilum and also left pleural effusion. Cytology of the effusion revealed adenocarcinoma. She was first treated with Adriamycin, 5-FU and Cyclophosphamide, but no significant response was noted. But, after two courses of chemotherapy containing cisplatin (80 mg/m2) and vindesine (3 mg/m2), the coin lesion of the lung and pleural effusion disappeared. The osteolytic bone change of the pelvic bone also improved. The serum CEA level decreased from 34.2 ng/ml to 4.2 ng/ml. These results suggest that cisplatin and vindesine were effective for lung and bone cancers metastatic from adenocarcinoma of the breast.
