The area under the receiver operating characteristic (ROC) curve for predicting the pathological grade of lung adenocarcinoma using the consolidation\u2013tumor ratio (CTR) and the solid volume ratio (SVR) were 0.761 and 0.777, respectively. The areas under the ROC curves (AUCs) for predicting lymph node metastasis were 0.804 and 0.873, respectively. Multivariate logistic regression analysis suggested that the SVR was an independent predictor of highly malignant lung adenocarcinoma pathology, while the SVR and pathological grade were independent predictors of lymph node metastasis. The sensitivity of predicting the pathological grading of lung adenocarcinoma based on SVR &gt;5% was 97.2%, with a negative predictive value of 96%. The sensitivity of predicting lymph node metastasis based on SVR &gt;47.1% was 97.3%, and the negative predictive value was 99.5%.<\/jats:p><jats:p>\n          Conclusion\u2003The SVR has greater diagnostic value than the CTR in the preoperative prediction of pathologic grade and lymph node metastasis in stage cT1-stage lung adenocarcinoma patients, and the SVR may replace the diameter and CTR as better criteria for guiding surgical implementation.<\/jats:p>","DOI":"10.1055\/a-2380-6799","type":"journal-article","created":{"date-parts":[[2024,8,6]],"date-time":"2024-08-06T23:10:02Z","timestamp":1722985802000},"page":"308-316","source":"Crossref","is-referenced-by-count":0,"title":["The
