The operative results by tumor location were evaluated in 17 curative cases of carcinoma of the colon with the confirmed presence of metastasis to the N3 lymph nodes. There were 7 cases of the left-side colon cancer and 10 cases of the right-side colon cancer. The results revealed that the 10-year survival rate of the left-side colon cancer was 67%, better than that of the right-side colon cancer, which was 38%. But there were no significant differences. The 10-year survival rate of the all cases was 48% and as good as that of curative cases with metastasis limited to the N2 lymph nodes. 9 out of the 10 cases of the right-side colon cancer had main lymph node metastasis and 2(22%) of these 9 cases showed subpyloric lymph node metastasis. Both 2 cases scored a 10-year survival. So it is suggested that the frequency of subpyloric lymah node metastasis is high when main lymph node metastasis is present and the subpyloric lymph node dissection is effective in such cases.
