DCA analysis showed that the prognosis model had an acceptable predictive value in predicting the death risk in 2 years (Figure 5(d)) and 3 years (Figure 5(e)), ITGA4 C − index = 0.623 (0.577-0.669), the lymph node metastasis rate C − index = 0.647 (0.593-0.702), and the combined C − index = 0.705 (0.656-0.753). This evidence concerns the gene ITGA4 and metastatic malignant neoplasm in the lymph nodes.
