ABSTRACT
BACKGROUND AND OBJECTIVES:
Periampullary adenocarcinoma (PAC) is stratified anatomically ampullary adenocarcinoma (AA), distal cholangiocarcinoma (DCC), duodenal adenocarcinoma (DA), and pancreatic ductal adenocarcinoma (PDAC). We aimed to determine differences in incidence, prognosis, and treatment in stage-matched PAC patients in a longitudinal study.METHODS:
PAC patients were identified in The National Cancer Database from 2004 to 2012. Clinicopathological variables were compared between subtypes. Covariate-adjusted treatment use and OS were compared.RESULTS:
The 116 705 patients with PAC were identified 1320 (9%) AA, 3732 (3%) DCC, 7142 (6%) DA, and 95 511 (82%) PDAC. DA, DCC, and PDAC were associated with worse survival compared with AA (hazard ratio [HR], 1.10; 95% CI, 1.1-1.1; HR, 1.50; 95% CI, 1.4-1.6, and HR, 1.90; 95% CI, 1.8-1.9). Among resected patients, DA was associated with improved survival compared with AA (HR, 0.70; 95% CI, 0.67-0.75); DCC and PDAC were associated with worse survival (HR, 1.41; 95% CI, 1.31-1.53 and HR, 2.041; 95% CI, 1.07-2.12). Resected AA, PDAC, and DA, but not DCC, demonstrated significantly improved survival over the studied period. While all patients had increased adjuvant therapy (AT) receipt over time (P < 0.001), only patients with PDAC had increased neoadjuvant therapy (NAT) receipt ( P < 0.001).CONCLUSION:
Resected PDAC, AA, and DA were associated with clinically significant improved survival over time, mirroring a concurrent associated increased receipt of AT.Palabras clave
