[Adenocarcinoma of the appendix. A multicenter study from AURC].
Thirty-two patients with primary adenocarcinoma of the appendix were studied in this collective review. Diagnosis was never suspected preoperatively. Immediate operation was performed in 21 patients with a diagnosis of acute appendicitis. At operation, tumor of the appendix was only identified in 50 percent of the 32 patients. One patient with an obstructing tumor and peritoneal involvement died postoperatively. Estimated survival rate was 46% at five years. Probability of survival was unrelated to the histologic tumor type but significantly correlated with the extent of tumor spread. Right hemicolectomy led to a significant increase in survival compared with appendectomy alone and to a significant decrease in risk of recurrence. In Dukes' B2 and C patients, differences in the survival curves were in favor of right hemicolectomy. In patients with pseudomyxoma peritonei, long-term survival was obtained by repeated laparotomy with resection of mucinous material. Our results indicate that, in good risk patients, right hemicolectomy performed as first or second operation, provides better results than appendectomy alone.
