The primary aim of this population-based study is to investigate how a high resection rate of pancreaticoduodenectomy affects overall survival among patients aged ≥70 years with pancreatic ductal adenocarcinoma. The secondary aim is to determine if a high resection rate of pancreaticoduodenectomy increases perioperative morbidity.
Study Type
OBSERVATIONAL
Enrollment
5,123
All groups are divided into one high- and one low resection rate group depending on percentage of patients with pancreatic ductal adenocarcinoma resected per county and year (first three groups) and resection rate of pancreaticoduodenectomy per 100 000 inhabitants per county (last three groups)
Overall survival
Overall survival among patients aged 70 years and over with pancreatic ductal adenocarcinoma in the pancreatic head
Time frame: A little more than 10 years (from first patient to vital status)
Severe complications after pancreaticoduodenectomy
The rate of severe complications among patients aged 70 years and over who had undergone pancreaticoduodenectomy for any reason
Time frame: Around 10 years (patients diagnosed between 1 January 2010 and 31 December 2018, latest dismissal from hospital january 2020)
