Among the 112 differentially expressed genes, 25 were associated with lymph node metastasis, 13 with TNM stage, and 7 genes (SCARNA7, AC105999.2, RANBP20P, RN7SL151P, SYNPR, AL512638.1, and TMIGD1) were associated with both lymph node metastasis and TNM stage. This evidence concerns the gene SYNPR and metastatic malignant neoplasm in the lymph nodes.
