Abstract
We analyzed clinicopathological features of ten patients with primary appendiceal carcinoma experienced during 1986 to 2007, which accounted for 0.79% of all resected colorectal carcinomas in our hospital. The mean age was 59.7 years, and the male to female ratio 7 : 3. The diagnosis of appendiceal carcinoma could be made preoperatively in only one case. We performed ileocecal resection in 5 cases, right hemicolectomy in one, and appendectomy in three. Ileocecal resection was performed in one case as an additional surgery after appendectomy. Regarding the histologic type, the tumor was mucinous cystadenocarcinoma in five cases, and adenocarcinoma in five cases. The tumor depth was classified as ‘ss' or deeper in all cases. Regarding clinicopathological staging, 7 cases were in StageII, and 3 cases StageIV. The StageIV cases included lymph node metastasis in one case (10%), liver metastasis in one (10%), and peritoneal dissemination in three (30%). Eight cases remained alive, five of them without recurrence, but two cases died from peritoneal dissemination. The type of recurrence in all cases was peritoneal dissemination. Primary appendiceal carcinoma is very difficult to diagnose preoperatively, most cases are diagnosed as advanced carcinoma, especially with peritoneal dissemination. Multidisciplinary treatment is required for improvement of the outcome of appendiceal carcinoma.
