BackgroundSurgical resection is an important factor in the curative treatment of gastric cancer. However a variety of aspects of surgical treatment that potentially influence outcome are still not well defined. This study aims to assess the influence of hospital type, referral pattern and proximal or distal location of the tumour on the ultimate survival.MethodsFrom January 1994 to January 2007, a total of 5245 patients were diagnosed with gastric adenocarcinoma in the region of the Comprehensive Cancer Centre North-East Netherlands. Hospitals in this region were categorized into three types: teaching university (TU), teaching non-university (TNU), and non-teaching hospitals (NT). The influence of hospital type, referral for surgery and location of the tumour on the relative survival of operated patients was studied.ResultsOf the 5245 patients, 2334 patients underwent surgery. For operated patients, the 5-year relative survival was 42.5% for the TU versus 34.0% and 35.5% for respectively TNU and NT hospitals (p = 0.064), with no difference (p = 0.38) in relative survival (25.6-31.9%) in the proximal tumours. A significant difference was found between the hospitals in the 5-year relative survival in the distal tumours; 59.7% in the TU versus 36.4% in the TNU and 36% in the NT (p = 0.03 univariate), however this was not confirmed in the multivariate analysis (p = 0.184). High referral centres did not perform better as far as survival is concerned than low referral hospitals. In conclusion the hospital type in our region did not significantly influence outcome of surgery for gastric cancer.Copyright 2010 Elsevier Ltd. All rights reserved.
