| Abstract |
A 57-year-old woman had been diagnosed with sigmoid colon cancer at surgery for ovarian cancer, and underwent simultaneous radical resection. Because of the pathological diagnosis of sigmoid cancer with ovarian metastasis, adjuvant chemotherapy was scheduled, with Leucovorin(LV)25 mg. This was immediately followed with 5-fluorouracil(5-FU)500 mg, via a 2-hour systemic intravenous infusion daily for 5 consecutive days, with courses repeated at 5 weeks, followed by maintenance once every 1 or 2 weeks for 2 years. There had been no evidence of recurrence for 10 years after surgery; however, peritoneal recurrence and a thyroid tumor were found using computed tomography(CT)at the 10-yearsur veillance. Chemotherapy with mFOLFOX6+bevacizumab was initiated because the peritoneal recurrence was determined to be unresectable and because of the metastasis to the thyroid. Chemotherapy was maintained, except for oxaliplatin(L-OHP)due to toxicity, with shrinkage of the peritoneal tumor; however, it was difficult to maintain the chemotherapy due to toxicity. Eleven months after initiation of chemotherapy, lung and bone metastases were detected, and she subsequently died.
