A total of 773 cases of colorectal carcinoma were surgically treated in our department for the past 18 years, and 196 of those cases were performed non-curative resection (relative non-curative in 52 and absolute non-curative resection in 144), and 63 tumors were not resected. As regards tumor locations, the frequencies of the non-curative resection were as high as more than 30% in the descending colon, cecum and transeverse colon. Histologically, non-curative resection cases became predominant in moderately differentiated adenocarcinomas, mucinous carcinomas and signet-ring cell carcinomas. Factors related to relative non-curative resection were lymph node metastasis (N) in 45 cases, liver metastasis (H) in 3, peritoneal dissemination (P) in 3, and H with P in one. Factors related to absolute non-curative resection were cancer infiltration on the resected wall edge in 48 cases, H in 45, P in 18, N in 10, distant metastasis in 2, and concomitant over 2 factors in 21. The five-year survival rates were 82.9% and 52.4% in absolute and relative curative resections versus 44.8% and 8.0% in relative and absolute non-curative resections, respectively. |
