[Case report of long-term survival obtained for advanced sigmoid colon cancer with para-aortic lymph nodes by resection and chemotherapy].

The patient was a 66-year-old male. He underwent sigmoidectomy with D1 for an advanced sigmoid colon cancer with massive metastasis to the para-aortic lymph nodes. After the resection he underwent chemotherapy, and CT showed that the para-aortic lymph node metastasis had disappeared. However, CT showed other lymph node(No. 252, No. 273 lt)swelling. We therefore resected No. 252 and No. 273 lt lymph nodes. Two years after the resection the patient is alive and shows no sign of recurrence while being without chemotherapy.
