Diagnostic accuracy of combined TCF-21 protein expression and computed tomography morphological features for predicting microvascular invasion in early-stage non-small cell lung cancer
Background Preoperative identification of microvascular invasion (MVI) in clinically early-stage non-small cell lung cancer (NSCLC) remains difficult because microscopic vascular spread cannot be reliably inferred from tumor size or nonspecific computed tomography (CT) features alone. This diagnostic accuracy study aim...
