A new approach to predict lymph node metastasis in solid lung adenocarcinoma: a radiomics nomogram

Lung cancer is the leading cause of cancer deaths worldwide. Non-small cell lung cancer (NSCLC) accounts for about 85% of all lung cancers (1). Radical resection, including complete tumor resection and systematic lymph node (LN) dissection, is the standard treatment for I–IIIB stage NSCLC. LN metastasis (LNM) is an important factor affecting prognosis: 5-year survival with LNM is 26–53% (2). Therefore, noninvasive preoperative evaluation of LNM is important for lung cancer staging, surgical planning, and prognosis
