[A case of esophageal cancer successfully treated by chemoradiotherapy after resection for multiple liver metastasis of sigmoid colon cancer].

The patient was a 56-year-old man. Colonoscopic findings showed a cancerous lesion of the sigmoid colon and we performed curative sigmoidectomy. Four months after the operation, abdominal CT scan revealed multiple metastatic lesions in the liver. We performed lateral segmentectomy and partial resection of the S4, S6, S8 segments and cannulation for hepatic arterial infusion chemotherapy. Continuous hepatic arterial infusion chemotherapy with 5-FU (1,000 mg/body/day) was performed for two weeks as a postoperative adjuvant chemotherapy. Immediately after the therapy, endoscopic examination for upper digestive tract showed a 0-lpl type cancer lesion in the middle of the thoracic esophagus. Concurrent chemoradiotherapy with low-dose FP was efficacious and a complete response was obtained. The patient has survived for nine months after the operation without any sign of recurrence. It is suggested that concurrent chemoradiotherapy an effective treatment for esophageal cancer.
