Patients undergoing surgery were categorized as local tumor excision or radical resection. Five-year overall survival (OS) was estimated using Kaplan-Meier analysis, and multivariable Cox proportional hazards analysis was used to identify factors associated with OS. A sensitivity analysis was also performed in the well-differentiated neuroendocrine tumor subgroup.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      7285 patients were included; 6638 (91.1%) underwent local excision and 647 (8.9%) radical resection. The annual number of surgically treated cases increased from 234 in 2004 to 778 in 2023. 83.0% of tumors with known grade were low grade, and 90.6% of tumors with known clinical stage were stage I. Radical resection was associated with larger tumors, higher grade, more advanced stage, lymphovascular invasion, and liver metastases (all\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; .001). Five-year OS was higher after local excision than radical resection (97.5% vs 85.7%,\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; .001). In the full multivariable model, radical resection was associated with worse OS (HR 3.43, 95% CI 1.60-7.36;\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = .002); however, this association was no longer statistically significant in the well-differentiated tumor subgroup (HR 2.52, 95% CI 0.97-6.54;\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = .057).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The number of surgically treated EORNET cases substantially increased over time.
