Cephalic Duodenopancreatectomy 10 or More Years Ago

Brief summary

In view of the similarities of the surgical set-ups of partial gastrectomies and cephalic duodenopancreatectomies, and the increased risk of gastric cancer after early partial gastrectomy, it is possible that the former pancreatic cephalic duodenopancreatectomy pancreaticoduodenectomy (CPD) is also associated with the occurrence of stomach cancer. The investigators expect a high rate of cancer and high grade dysplasia in these patients based on literature data and available data on gastric cancer after partial gastrectomy. Participants with lesions to be discovered will benefit from earlier medical management of less advanced tumor lesions, with improved prognosis. The primary objective of this study is to evaluate the incidence of gastric cancer or high grade dysplasia in patients with old CPP CPD (10 years or older) and who performed the endoscopy protocol. The cohort will consist of all eligible patients identified from pathology registries and PMSI data from participating centers (patients living 10 years after CPDP, with no previous history of gastric cancer before entering the cohort). Entry into the cohort (beginning of exposure) will be 10 years after CPD. If a gastric cancer has been diagnosed previously at the beginning of the current study (2019) with histological documentation present in the medical file, no new endoscopy will be performed and the patient will be considered as a new case on the date of histological diagnosis of cancer. Of the patients included in the cohort, some will be eligible to perform the endoscopy added for research. This group will be the sample in which the primary endpoint will be measured. 1\.

Detailed description

In view of the similarities of the surgical set-ups of partial gastrectomies and cephalic duodenopancreatectomies, and the increased risk of gastric cancer after early partial gastrectomy, it is possible that the former pancreatic cephalic duodenopancreatectomy (CPD) is also associated with the occurrence of stomach cancer. The investigators expect a high rate of cancer and high grade dysplasia in these patients based on literature data and available data on gastric cancer after partial gastrectomy. Participants with lesions to be discovered will benefit from earlier medical management of less advanced tumor lesions, with improved prognosis. The investigators results will provide an argument for conducting larger analytical studies and will also provide useful information for the design of these studies. These studies will eventually identify a gastric cancer screening strategy among patients with previous CPDP. Screening programs in groups at higher risk of gastric cancer among patients with CPDP could provide significant benefits in terms of gastric cancer mortality and quality of life, as well as medico-economic positive for the health care system. The primary objective of this study is to evaluate the incidence of gastric cancer or high grade dysplasia in patients with old CPDP (10 years or older) and who performed the endoscopy protocol. The primary endpoint is the incidence rate of gastric cancer or high grade dysplasia in patients who had CPDP 10 years or more ago. The cohort will consist of all eligible patients identified from pathology registries and PMSI data from participating centers (patients living 10 years after CPDP, with no previous history of gastric cancer before entering the cohort). Entry into the cohort (beginning of exposure) will be 10 years after CPD. If a gastric cancer has been diagnosed previously at the beginning of the current study (2019) with histological documentation present in the medical file, no new endoscopy will be performed and the patient will be considered as a new case on the date of histological diagnosis of cancer. The collection of data will be retrospective for these patients. Of the patients included in the cohort, some will be eligible to perform the endoscopy added for research. This group will be the sample in which the primary endpoint will be measured. 1\. Recruitment of patients with cephalad cephalic duodenopancreatectomy 10 or more years ago 2.
