Abstract
From 1977 to 1984, 56 patients with colon cancer adherent to other organs were operated upon. Twenty-three (41 percent) underwent palliative treatment without resection. The mean survival in this group was 6 months. The results of en bloc resection were evaluated in 33 patients (59 percent) with colon carcinoma and tumor growth in adjacent organs. Pathologic staging was based on Dukes' (Astler and Coller) classification. Dukes' B carcinoma was shown in 15 patients. Dukes' C in 14 patients, and Dukes' D in four patients. The 4-year survival rate was as follows: Dukes' B, 47 percent; Dukes' C, 29 percent; and Dukes' D, 0 percent. The 4-year survival rate for the whole group was 33 percent. The postoperative morbidity and mortality were 6 percent and 3 percent, respectively. Colon cancer with involvement of adjacent structures should not be regarded as an incurable Dukes' D carcinoma; en bloc resection is indicated and can be performed with acceptable morbidity and mortality.
