[Surgical treatment of colon cancer]

The treatment of early colon cancer limited lamina propria mucosa is endoscopic polypectomy. If invasion into the submucosal layer is present, usual colectomy with regional lymph adenectomy is indicated. Colon cancer without distant metastasis is treated by colectomy with regional lymph adenectomy. Right hemicolectomy, transverse colectomy, left hemicolectomy, and sigmoidectomy are indicated according to the location of the cancer. Five years survival rate for curative resection in 96 personal cases was 80.8%. Palliative resection was available to prolong the survival time. Mean survival time after palliative resection was 14 months, but in unresectable case it was 4 months.
