Outcomes of neoadjuvant chemotherapy versus chemoradiation among patients with resected pancreatic head adenocarcinoma.
2016
398 Background: Increasing use of neoadjuvant therapy in pancreatic cancer has been reported. We compared patterns of practice and outcomes of neoadjuvant chemotherapy (nCHT) versus chemoradiation (nCRT) among pancreatic cancer pts receiving pancreaticoduodenectomy. Methods: National Cancer Data Base pancreatic head adenocarcinoma patients (pts) diagnosed between 2003 and 2011 treated by nCHT or nCRT followed by pancreaticoduodenectomy. Backward elimination logistic and Cox regression models were used. Primary outcome measures were 30-day and 90-day postsurgical mortality and overall survival; adjusted odds (aOR) & hazard ratios (aHR) and 95% confidence intervals (CI) are reported. Results: In all 1,432 pts received neoadjuvant treatment with nCHT (n = 523) or nCRT (n = 909). Odds of 30-day mortality were influenced by age (aOR 1.03, CI 0.99-1.06,p = 0.077), average annual resection volume of facility (aOR 0.98, CI 0.97-1.00, p = 0.135), and household income quartile (aOR 1.94, CI 0.97-3.90, p = 0.060), b...
