Staging laparoscopy in gastric cancer surgery. A population-based cohort study in patients undergoing gastrectomy with curative intent

BackgroundStudies on the value of a staging laparoscopy in detecting metastases gastric cancer patients show great variation. This study investigates avoidable surgery rate with and without scheduled for curative intent.MethodsThis population-based cohort included all an intentional resection potentially curable adenocarcinoma, between 2011 2016, registered Dutch Upper GI Cancer audit. Patients were compared. The primary outcome was (detection and/or locoregional non-resectable tumor during gastrectomy). Secondary outcomes negative predictive value, postoperative morbidity pathology parameters.Results2849 who underwent gastrectomy included. 414 2849 (14.5%) before initiation treatment. 16.2% group, compared to 8.5% non-staging group (P < 0.001), resulting 83.8%. remained significantly different after correction possible confounders. main reason not executing presence distant metastasis both groups. cT cN stage higher laparoscopy.ConclusionsThe had cTN pTN stage, implicating selection more advanced disease laparoscopy. Despite laparoscopy, found, suggesting low sensitivity or non-resectability this patient group.
