Patients were divided into two groups according to the lymph node dissection technique: lobe-specific lymph node dissection and systematic lymph node dissection. Survival outcomes and postoperative complications were compared between the groups. Multivariate Cox regression analysis was performed to identify prognostic factors affecting survival.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Postoperative complications occurred in 86 patients (19.5%). Complications were significantly less frequent in the lobe-specific lymph node dissection group compared to the systematic lymph node dissection group (9.4% vs. 22.4%, respectively; p\u2009=\u20090.027). The overall annual survival rate was 68.3%. The 5-year survival rate was significantly higher in female patients than in male patients (83.6% vs. 61.7%, p\u2009&lt;\u20090.001). The 5-year survival rate was 69.3% in patients who underwent systematic lymph node dissection and 64.8% in those who underwent lobe-specific lymph node dissection, with no statistically significant difference between the two techniques (p\u2009=\u20090.332). In multivariate Cox regression analysis, advanced age was not a significant predictor of survival (p\u2009=\u20090.119, HR\u2009=\u20090.714, 95% CI: 0.467\u20131.090), whereas male gender was identified as an independent poor prognostic factor (p\u2009=\u20090.01, HR\u2009=\u20092.781, 95% CI: 1.506\u20135.138).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Lymph node dissection remains a critical component of surgical treatment in early-stage lung cancer. The comparable survival outcomes and lower complication rates observed with lobe-specific lymph node dissection suggest that it may be a preferable option in selected patients with stage I non-small cell lung cancer. Nevertheless, prospective multicenter studies are required to confirm these findings.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/02184923261456799","type":"journal-article","created":{"date-parts":[[2026,6,9]],"date-time":"2026-06-09T09:20:02Z","timestamp":1780996802000},"page":"535-541","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["The effects of lymph node dissection techniques on survival in stage I non-small cell lung cancer"],"prefix":"10.1177","volume":"34","author":[{"given":"Esra","family":"Yamansavc\u0131 \u015eirzai","sequence":"first","affiliation":[{"name":"Department of Thoracic Surgery, Dr Suat Seren Chest Diseases and Thoracic Surgery Training and Research Hospital, Istanbul, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1448-2448","authenticated-orcid":false,"given":"Gizem","family":"\u00d6z\u00e7\u0131b\u0131k I\u015f\u0131k","sequence":"additional","affiliation":[{"name":"Yedikule Chest Diseases and Thoracic Surgery Training and Research Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"O\u011fuzhan","family":"Bayraktar","sequence":"additional","affiliation":[{"name":"Yedikule Chest Diseases and Thoracic Surgery Training and Research Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Celal Bu\u011fra","family":"Sezen","sequence":"additional","affiliation":[{"name":"Yedikule Chest Diseases and Thoracic Surgery Training and Research Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"\u00d6zkan","family":"Saydam","sequence":"additional","affiliation":[{"name":"Yedikule Chest Diseases and Thoracic Surgery Training and Research Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ahmet","family":"\u00dc\u00e7vet","sequence":"additional","affiliation":[{"name":"Department of Thoracic Surgery, Dr Suat Seren Chest Diseases and Thoracic Surgery Training and Research Hospital, Istanbul, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,6,9]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1097\/00000658-199801000-00020"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1097\/JTO.0000000000000546"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00595-013-0772-5"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.21037\/jtd.2018.04.137"},{"key":"e_1_3_3_6_2","doi-asserted-by":"publisher","DOI":"10.1159\/000521288"},{"key":"e_1_3_3_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jtho.2016.05.014"},{"key":"e_1_3_3_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.cllc.2022.08.005"},{"key":"e_1_3_3_9_2","doi-asserted-by":"publisher","DOI":"10.1245\/s10434-019-07926-3"},{"key":"e_1_3_3_10_2","doi-asserted-by":"publisher","DOI":"10.21037\/jtd.2017.07.23"},{"key":"e_1_3_3_11_2","article-title":"Clinical stage-specific prognostic impact of adequate lymphadenectomy in early-stage lung cancer","volume":"67","author":"Liu C","year":"2024","unstructured":"Liu C, Lin KH, Chen HM, et al.
