摘要
A 52-year-old woman was presented with abdominal distension. Chest-abdominal CT showed some tumors in the left breast, enlarged axillary lymph nodes, ovary metastasis peritoneal thickening, a large amount of ascites. The diagnosis of needle biopsy in the breast mass was invasive ductal carcinoma, Luminal A type. The large amount of ascites decreased after the start of administration of fulvestrant and CDK4/6 inhibitor(PAL). Also chest and abdominal CT showed reduction of all lesions. We found the high expression of cyclin D1 protein and the negative of p16 protein in tissues of the needle biopsy. Fifty months later, she continues to do good ADL and PR status. We experienced a case of metastatic breast cancer with massive ascites and peritoneal metastasis that was successfully treated with a CDK4/6 inhibitor(PAL)and achieved long- term survival.
