Purpose: This study was undertaken to describe the clinicopathologic characteristics and evaluate the appropriate management of appendiceal tumors.
Methods: During 5 years between Sep. 2000 and Sep. 2005, 28 appendiceal tumors were identified in a retrospective review of 3,744 cases of appendectomy or right hemicolectomy pathology.
Results: Carcinoids were found incidentally as appendicitis. Mucinous cystadenomas were common in women older than 50 aged; half of the cases presented with appendicitis and the other half presented with non??specific abdominal symptoms such as palpable mass, intestinal obstruction and intussusception. Carcinomas were common in the older patients (mean age: 62.8 years) and this presented as periappendiceal abscess. Right hemicolectomy was undertaken when there was evidence of tumor spread beyond the resection margin, and carcinoma and tumors were located in the appendiceal base. Recurrence and metastasis were identified only in the carcinoma cases.
Conclusion: Most appendiceal tumors presented with appendicitis and periappendiceal abscess. One stage curative resection was possible in more than 76% of the patients, and the prepoperative diagnosis rate was less than 35%.
The preoperative diagnosis did not have much impact on the clinical course, and the postoperative pathology was important in determining the additional treatment. Close follow up is needed for the early detection of recurrence, and all the carcinomas that were advanced as serosal involvement, peritoneal seeding and liver metastasis.
