Methods: Surveillance, Epidemiology and End Results (SEER) database [2004–2015] was explored and AJCC 6th, 7th, and 8th versions were assigned for each patient. Through Kaplan-Meier estimates, overall survival analyses were conducted. Cox regression analysis (adjusted for age, race, gender, sub-site, grade and surgical treatment) was conducted for cancer-specific survival and additionally, pairwise hazard ratio comparisons were performed. 
Results: A total of 2,997 small intestinal adenocarcinoma patients were eligible and included in the analysis. Overall survival was compared according to the three AJCC staging systems. For the three versions, the P value for the trend in overall survival was significant (P},
