We used the chi-square test to compare baseline data between groups and found no significant differences. We used Cox regression analysis to screen out independent prognostic factors affecting survival time and used these factors to construct the nomogram. The ROC curve, calibration curve, C-index, and DCA curve were used to verify the model. The final results showed that our predictive model had good predictive ability, and showed better predictive ability compared with tumor-node-metastasis (TNM) staging. We also achieved good results using data of our center for external verification.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The present nomogram could accurately predict prognosis in older patients with lung adenocarcinoma.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/03000605241240993","type":"journal-article","created":{"date-parts":[[2024,4,12]],"date-time":"2024-04-12T07:01:37Z","timestamp":1712905297000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Predictors of cancer-specific survival and overall survival among patients aged \u226560 years with lung adenocarcinoma using the SEER database"],"prefix":"10.1177","volume":"52","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7984-581X","authenticated-orcid":false,"given":"Feiyang","family":"Li","sequence":"first","affiliation":[{"name":"Ward 2, Department of Medical Oncology, Lixin People\u2019s Hospital of Bozhou City, Anhui Province, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fang","family":"Li","sequence":"additional","affiliation":[{"name":"Ward 1, Department of Medical Oncology, Affiliated Hospital of Qinghai University, Qinghai Province, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dong","family":"Zhao","sequence":"additional","affiliation":[{"name":"Ward 2, Department of Medical Oncology, Lixin People\u2019s Hospital of Bozhou City, Anhui Province, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4463-995X","authenticated-orcid":false,"given":"Haowei","family":"Lu","sequence":"additional","affiliation":[{"name":"Ward 2, Department of Medical Oncology, Lixin People\u2019s Hospital of Bozhou City, Anhui Province, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2024,4,12]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.3322\/caac.21660"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ccm.2019.10.001"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1001\/jamaoncol.2021.4932"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ebiom.2020.102959"},{"key":"e_1_3_3_6_2","doi-asserted-by":"publisher","DOI":"10.1002\/cncr.33078"},{"key":"e_1_3_3_7_2","first-page":"352","article-title":"Development and validation of prognostic nomogram for lung cancer patients below the age of 45 years","volume":"21","author":"Dai L","year":"2021","unstructured":"Dai L, Wang W, Liu Q, et\u00a0al.
