The recommended minimal ELN number in PaC to accurately stage cancer varies greatly across guidelines, and the optimal number especially to adequately stratify patient survival has not yet been established.Population-based data on patients with stage I to II PaC resected in 2003 to 2015 from the US Surveillance, Epidemiology, and End Results (SEER)-18 Program and Netherlands National Cancer Registry (NCR) were analyzed. Associations of ELN number with stage migration and survival were evaluated using multivariable-adjusted logistic and Cox regression models, respectively. The series of odds ratios (ORs) for negative-to-positive node stage migration and hazard ratios (HRs) for survival with more ELNs were fitted using a LOWESS smoother, and structural breakpoints were determined by Chow test.Overall 16,241 patients were analyzed. With increasing ELN number, both cohorts exhibited significant proportional increases from node-negative to node-positive disease [ORSEER-18=1.05, 95% confidence interval (CI) = 1.04-1.05; ORNCR = 1.10, 95% CI = 1.08-1.12] and serial improvements in survival (HRSEER-18 = 0.98, 95% CI = 0.98-0.99; HRNCR = 0.98, 95% CI = 0.97-0.99) per additional ELN after controlling for confounders. Associations for stage migration and survival remained significant in most stratifications by patient, tumor, and treatment factors. Cut-point analyses suggested a minimal threshold ELN number of 11 and an optimal number of 19, which were validated both internally in the derivative US cohort and externally in the Dutch cohort with the ability to well discriminate different probabilities of both survival and stage migration.In stage I to II PaC, more ELNs are associated with more precise nodal staging, which might largely explain the survival association. Our observational study does not suggest causality, and does not encourage more extended lymphadenectomy before further randomized evidence is obtained. Our results robustly conclude 11 ELNs as the minimal and suggest 19 ELNs as the optimal cut-points, for evaluating quality of lymph node examination and possibly for stratifying postoperative prognosis. 000144568 536__ $$0G:(DE-HGF)POF4-313$$a313 - Krebsrisikofaktoren und Prävention (POF4-313)$$cPOF4-313$$fPOF IV$$x0 000144568 588__ $$aDataset connected to CrossRef, PubMed, 000144568 7001_ $$0P:(DE-He78)bbfe0ebad1e3b608bca2b49d4f86bd09$$aJansen, Lina$$b1$$udkfz 000144568 7001_ $$0P:(DE-HGF)0$$aBalavarca, Yesilda$$b2 000144568 7001_ $$avan der Geest, Lydia$$b3 000144568 7001_ $$aLemmens, Valery$$b4 000144568 7001_ $$aGroot Koerkamp, Bas$$b5 000144568 7001_ $$avan Santvoort, Hjalmar C$$b6 000144568 7001_ $$aGrützmann, Robert$$b7 000144568 7001_ $$aBesselink, Marc G$$b8 000144568 7001_ $$0P:(DE-He78)01ef71f71b01a3ec3b698653fd43fe86$$aSchrotz-King, Petra$$b9$$udkfz 000144568 7001_ $$0P:(DE-He78)90d5535ff896e70eed81f4a4f6f22ae2$$aBrenner, Hermann$$b10$$eLast author$$udkfz 000144568 773__ $$0PERI:(DE-600)2002200-1$$a10.1097/SLA.0000000000003558$$gp. 1 -$$n6$$pe554-e563$$tAnnals of surgery$$v274$$x0003-4932$$y2021 000144568 909CO $$ooai:inrepo02.dkfz.de:144568$$pVDB 000144568 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-He78)448ff49e51672d79b4747339ac15c898$$aDeutsches Krebsforschungszentrum$$b0$$kDKFZ 000144568 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-He78)bbfe0ebad1e3b608bca2b49d4f86bd09$$aDeutsches Krebsforschungszentrum$$b1$$kDKFZ 000144568 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-HGF)0$$aDeutsches Krebsforschungszentrum$$b2$$kDKFZ 000144568 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-He78)01ef71f71b01a3ec3b698653fd43fe86$$aDeutsches Krebsforschungszentrum$$b9$$kDKFZ 000144568 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-He78)90d5535ff896e70eed81f4a4f6f22ae2$$aDeutsches Krebsforschungszentrum$$b10$$kDKFZ 000144568 9131_ $$0G:(DE-HGF)POF4-313$$1G:(DE-HGF)POF4-310$$2G:(DE-HGF)POF4-300$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$aDE-HGF$$bGesundheit$$lKrebsforschung$$vKrebsrisikofaktoren und Prävention$$x0 000144568 9132_ $$0G:(DE-HGF)POF4-313$$1G:(DE-HGF)POF4-310$$2G:(DE-HGF)POF4-300$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$aDE-HGF$$bGesundheit$$lKrebsforschung$$vKrebsrisikofaktoren und Prävention$$x0 000144568 9141_ $$y2021 000144568 915__ $$0StatID:(DE-HGF)0410$$2StatID$$aAllianz-Lizenz 000144568 915__ $$0StatID:(DE-HGF)0420$$2StatID$$aNationallizenz 000144568 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS 000144568 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline 000144568 915__ $$0StatID:(DE-HGF)0310$$2StatID$$aDBCoverage$$bNCBI Molecular Biology Database 000144568 915__ $$0StatID:(DE-HGF)0320$$2StatID$$aDBCoverage$$bPubMed Central 000144568 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bANN SURG : 2017 000144568 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bClarivate Analytics Master Journal List 000144568 915__ $$0StatID:(DE-HGF)0110$$2StatID$$aWoS$$bScience Citation Index 000144568 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection 000144568 915__ $$0StatID:(DE-HGF)0111$$2StatID$$aWoS$$bScience Citation Index Expanded 000144568 915__ $$0StatID:(DE-HGF)1110$$2StatID$$aDBCoverage$$bCurrent Contents - Clinical Medicine 000144568 915__ $$0StatID:(DE-HGF)1030$$2StatID$$aDBCoverage$$bCurrent Contents - Life Sciences 000144568 915__ $$0StatID:(DE-HGF)9905$$2StatID$$aIF >= 5$$bANN SURG : 2017 000144568 9202_ $$0I:(DE-He78)C070-20160331$$kC070$$lC070 Klinische Epidemiologie und Alternf.$$x0 000144568 9201_ $$0I:(DE-He78)C070-20160331$$kC070$$lC070 Klinische Epidemiologie und Alternf.$$x0 000144568 9201_ $$0I:(DE-He78)C120-20160331$$kC120$$lPräventive Onkologie$$x1 000144568 9201_ $$0I:(DE-He78)HD01-20160331$$kHD01$$lDKTK HD zentral$$x2 000144568 9200_ $$0I:(DE-He78)C070-20160331$$kC070$$lC070 Klinische Epidemiologie und Alternf.$$x0 000144568 980__ $$ajournal 000144568 980__ $$aVDB 000144568 980__ $$aI:(DE-He78)C070-20160331 000144568 980__ $$aI:(DE-He78)C120-20160331 000144568 980__ $$aI:(DE-He78)HD01-20160331 000144568 980__ $$aUNRESTRICTED
