Comparison of carcinoid tumors with the other tumors of appendix

Abstract

Aim: Carcinoid tumor is the most frequent primary tumor of the appendix which may reach up to 60% of all appendiceal neoplasms. We aimed to evaluate the incidental appendiceal carcinoid tumors following acute appendicitis analyzing the demographics, clinical, laboratory, pathological features and follow-up results of the patients. Material and Methods: We evaluated the patients retrospectively who had been operated for acute appendicitis between January 2006 and May 2018 . Results: We found 29 patients with carcinoid tumor among 7122 cases (0.4%) between 2006-2018. Median size of tumors was found to be 7.5 mm (Min: 0.8, max: 20 mm). While appendectomy was sufficient for 27 of the patients, right hemicolectomy was performed for 2 cases. When labaratory values were analysed the neutrophil / WBC ratio was significantly higher and lymphocyte count in the study group was significantly lower than control group (p < 0.05). The neutrophil / lymphocyte ratio was significantly higher than control group (p < 0.05). Conclusion: Evaluation of laboratory values at admission, histopathological examination of appendiceal specimens, early diagnosis of cancer and performing the appropriate treatment are required for the survival of patients.
