The feasibility of limited resection remains controversial; we retrospectively assessed lung cancer\u2010specific survival (LCSS) and overall survival (OS) in early stage non\u2010small cell lung cancer (NSCLC) to evaluate whether segmentectomy is comparable to standard lobectomy.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Patients with primary NSCLC of 20 mm or less who were diagnosed from 2000 to 2014 were extracted from the Surveillance, Epidemiology, and End Results (SEER) database. To compare the two surgical interventions, a propensity score analysis was performed between lobectomy and segmentectomy.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Of the 15 358 patients analysed, there were 14 549 lobectomies and 809 segmentectomies. The 5\u2010year OS was 76% for the lobectomy group and 74.4% for the segmentectomy group. There were no significant differences in OS or LCSS among patients who underwent lobectomy versus segmentectomy, as demonstrated by the propensity\u2010matched hazard ratio (HR) for OS (HR: 1.195, 95% CI: 0.993\u20131.439) and LCSS (HR: 1.124, 95% CI: 0.860\u20131.469). The inverse propensity\u2010weighted analysis also supported these results. Segmentectomy was more likely to be performed in elderly patients. In the subset of patients aged \u226575 years, the segmentectomy group demonstrated comparable OS (HR: 1.17, 95% CI: 0.87\u20131.58, <jats:italic>P<\/jats:italic> = 0.31) and LCSS (HR: 0.94, 95% CI: 0.59\u20131.51, <jats:italic>P<\/jats:italic> = 0.81), compared with the lobectomy group.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Equivalent OS and LCSS were demonstrated in patients with primary NSCLC of 20 mm or less without lymph node or distant metastasis.<\/jats:p><\/jats:sec>","DOI":"10.1111\/resp.13277","type":"journal-article","created":{"date-parts":[[2018,2,21]],"date-time":"2018-02-21T20:34:56Z","timestamp":1519245296000},"page":"695-703","source":"Crossref","is-referenced-by-count":44,"title":["Segmentectomy versus lobectomy in early non\u2010small cell lung cancer of 2 cm or less in size: A population\u2010based study"],"prefix":"10.1111","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2799-4570","authenticated-orcid":false,"given":"Mi Hyoung","family":"Moon","sequence":"first","affiliation":[{"name":"Department of Thoracic and Cardiovascular Surgery Seoul St. Mary's Hospital, Catholic University of Korea  Seoul Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6875-6918","authenticated-orcid":false,"given":"Young Kyu","family":"Moon","sequence":"additional","affiliation":[{"name":"Department of Thoracic and Cardiovascular Surgery Seoul St. Mary's Hospital, Catholic University of Korea  Seoul Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seok Whan","family":"Moon","sequence":"additional","affiliation":[{"name":"Department of Thoracic and Cardiovascular Surgery Seoul St. Mary's Hospital, Catholic University of Korea  Seoul Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2018,2,21]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1093\/jjco\/hyw148"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/0003-4975(95)00537-U"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.athoracsur.2004.01.024"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1378\/chest.12-2359"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jss.2012.11.052"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1378\/chest.09-2547"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1200\/JCO.2015.64.6729"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.21037\/jtd.2017.05.79"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1097\/JTO.0000000000000664"},{"key":"e_1_2_6_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ccm.2011.09.001"},{"key":"e_1_2_6_12_1","unstructured":"TravisWD BrambillaE NicholsonAG YatabeY AustinJHM BeasleyMB ChirieacLR DacicS DuhigE FliederDBet al.;WHO Panel.
