Methods: Patients that underwent gastrectomy between 2011 and 2016 were reviewed from the Dutch Upper Gastrointestinal Cancer Audit. Patients with &lt;15 and \u226515 LN retrieved were compared after propensity-score matching based on patient and tumor characteristics. The primary endpoint was 3-year overall survival. Results: A total of 2,047 patients were included in the study. After propensity score matching, 522 patients with \u226515 LNs were matched to 522 patients with &lt;15 LNs. There was no statistically significant difference in overall survival between both groups with 3-year survival rates of 56% versus 59%, respectively. Patients with \u226515 LNs had a more advanced pN-category. While median survival was higher for patients with \u226515 LNs versus &lt;15 LNs in the subgroups pN2, pN3a, and pN3b, no statistically significant differences were found. Similar results were found in the propensity score matched cohort using 23 LNs as cut-off. Conclusion: \u226515 LNs retrieved during gastrectomy for cancer was associated with higher pN-stage, likely as a result of stage migration. Three-year overall survival was comparable for patients with \u226515 LNs and patients with &lt;15 LNs retrieved.
