[A Case of Gastrointestinal Metastases of Breast Cancer Effectively Treated with Gemcitabine and Paclitaxel Combination Chemotherapy].

ABSTRACT

A 55-year-old woman was admitted to our hospital complaining of constipation and abdominal distention. She had a history of right breast surgery for cancer at the age of 48 years. An abdominalCT scan revealed tumors at the antrum of the stomach and the ascending colon, and the tumor at the ascending colon caused obstruction of the colon. She was diagnosed with breast cancer recurrence and was administered combination chemotherapy consisting of gemcitabine and paclitaxel. Ileus improved after this treatment, and she was discharged from the hospital and was able to receive outpatient chemotherapy. After 8 months, she experienced symptoms of ileus again, and conservative treatment was considered impossible. Therefore, she underwent distal gastrectomy and right hemicolectomy. Histological and immunohistological analyses confirmed that the tumors were breast cancer metastases. Chemotherapy with gemcitabine and paclitaxel helped our patient to return to daily life and improved her prognosis.
