We aimed to develop an AI prognostic model for surgically resected non-small cell lung cancer (NSCLC). This study enrolled 1049 patients with pathological stage I-IIIA surgically resected NSCLC at Kyushu University. We set 17 clinicopathological factors and 30 preoperative and 22 postoperative blood test results as explanatory variables. Disease-free survival (DFS), overall survival (OS), and cancer-specific survival (CSS) were set as objective variables. The eXtreme Gradient Boosting (XGBoost) was used as the machine learning algorithm. The median age was 69 (23-89) years, and 605 patients (57.7%) were male. The numbers of patients with pathological stage IA, IB, IIA, IIB, and IIIA were 553 (52.7%), 223 (21.4%), 100 (9.5%), 55 (5.3%), and 118 (11.2%), respectively. The 5-year DFS, OS, and CSS rates were 71.0%, 82.8%, and 88.7%, respectively. Our AI prognostic model showed that the areas under the curve of the receiver operating characteristic curves of DFS, OS, and CSS at 5 years were 0.890, 0.926, and 0.960, respectively. The AI prognostic model using XGBoost showed good prediction accuracy and provided accurate predictive probability of postoperative prognosis of NSCLC.Scientific reports15683https://www.ebi.ac.uk/biostudies/studies/S-EPMC10514331biostudies-literatureDevelopment of artificial intelligence prognostic model for surgically resected non-small cell lung cancer.PMC10514331Nakashima NMori MWakasu SKinoshita FYamashita TOno YTagawa TMatsumoto KOku YTakenaka THaratake NfalseDevelopment of artificial intelligence prognostic model for surgically resected non-small cell lung cancer.There are great expectations for artificial intelligence (AI) in medicine.
