The distribution of metastatic lymph nodes in 104 cases with right-sided colon cancer, in which curative resection had been performed, was studied. Lymph node (LN) metastasis along the bowel was not evident at a distance of more than 5 cm from the tumor, with the exception of two cases in which the tumor measured more than 8 cm in diameter. In cecal colon cancer, LN metastasis was recognized only in the nodes along the ileocolic artery, except for one case in which the tumor measured 8 cm in diameter, and in proximal ascending colon cancer, it was also recognized only in the nodes along the ileocolic artery. In mid-ascending colon cancer, LN metastasis was recognized extensively, regardless of tumor size. In distal ascending colon cancer, LN metastasis was recognized only in the nodes along the right colic artery, except for one case in which the tumor measured 8.5 cm in diameter, whereas in right-sided transverse colon cancer, it was not recognized in any nodes along the ileocolic artery, except for one case in which the timor measured 10 cm in diameter. These findings suggest that ileocecal resection may provide sufficient radicality for both cecal colon and proximal ascending colon cancers, and that surgical preservation of the ileocecal junction may be feasible for both proximal ascending colon and right-sided transverse colon cancers, except for cases in which the tumor measures more than 8 cm in diameter.
