The predicted 2-year survival rate of this patient can be obtained by comparing it with the lower scale and “survival probability.” For example, a male patient with pleural metastasis of lung adenocarcinoma with elevated CEA, lymph node metastasis, and pleural adhesion observed under thoracoscopy was treated with first-generation EGFR-TKIs. This evidence concerns the gene CEACAM5 and metastatic malignant neoplasm in the lymph nodes.
