BACKGROUND: Rates of nonoperative management of acute appendicitis and appendiceal adenocarcinoma have increased over a decade, but the presentation and outcomes of appendiceal adenocarcinoma over this period is not well-characterized.
METHODS: Patients with surgically resected Stage I-III appendiceal adenocarcinoma were identified from the 2006 to 2015 National Cancer Data Base and classified into two cohorts, 2006-2010 and 2011-2015, based on year of diagnosis. Three-year overall survival (OS) was analyzed using Cox proportional hazards regression and Kaplan-Meier survival estimates.
RESULTS: Of 4233 patients, 1369 (32.3%) and 2864 (67.7%) were diagnosed in 2006-2010 and 2011-2015, respectively. Following multivariable analysis, patients in 2011-2015 were more likely to be <40 years of age (6.4% vs. 4.7%, odds ratio [OR] 1.53, p .015), present with pT4 tumors (40.2% vs. 34.4%, OR 1.46, p .004), and undergo hyperthermic intraperitoneal chemotherapy (4.4% vs. 2.4%, OR 1.97, p .001). Comparing patients diagnosed in 2011-2015 to 2006-2010, adjusted 3-year OS was no different among all patients (81.1% vs. 79%, p .778).
CONCLUSIONS: There has been an increase in the proportion of patients with pT4 appendix tumors over time, primarily among older (≥60 years) patients. Even so, these shifts in presentation have not resulted in differences in survival outcomes.
