We report a case of high CEA advanced colon cancer, which we were able to down stage after treatment with FOLFIRI-1. The patient was a 56-year-old woman who had advanced sigmoid colon cancer with high CEA. It was suspected that the tumor had directly invaded the ovary by CT scan. For curative operation, hysterectomy was considered necessary. Neoadjuvant therapy was performed to avoid an extensive operation. After the fourth course, according to colonoscopy and CT findings, a significant tumor reduction was obtained. Sigmoid colorectomy with D3 nodal dissection was then performed. The histological diagnosis was pT1, pN0, PStage I. The histological effect was observed in lymph node metastasis. The patient was recurrence-free at her 3-year follow-up examination.
