Abstract

Data describing appendiceal tumor incidence and epidemiology is limited. We collated data from appendectomy pathology reports between 2005 and 2018 in our institution and examined patient epidemiological and appendectomy pathological features [1]. Overall, 8,328 appendectomies were performed at our institution over the pre-specified time period and 8,162 patients had sufficient epidemiological data to be included in the analysis. A total of 153 patients (1.9%) were diagnosed with appendiceal tumors, of which 57 (37.3%) were Appendiceal Neuroendocrine Neoplasm (ANEN), 35 (22.9%) were mucinous cystadenoma and 34 (22.2%) ovarian cancer metastases. We further examined the ANEN cases in order to characterize initial patient and tumor characteristics, to evaluate the performance of further investigations and interventions, and ultimately to study the behavior of these tumors over time.
