To compare gene expression profile between early T\u2010stage tongue cancer with cervical lymph node metastasis and late T\u2010stage tongue cancer without cervical metastasis, genomic data of following two groups was assessed; 1) group 1: T1\/2 and N2\/3 (n = 41), 2) group 2: T4 and N0 (n = 65). Using R and limma package in bioconductor program, differentially expressed genes (DEGs) were extracted. Gene ontology and pathway enrichment analysis were performed using the DAVID online tool. FFPE tissue of 285 patients were evaluated for the validation of relevant genes by imunofluorescence (IF) and immunohistochemical (IHC) stain.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 225 DEGs were found, and 50 genes were highly significant with absolute fold change over eight. Gene ontology and pathway enrichment analysis revealed that most of the upregulated genes were associated with actin cytoskeleton and included following genes: ANKRD23, NO3, PDLIM3, MUSTN1, TNNT3, MYBPC1, MB, MYH3, TTN, ACTA1, and ACTC1. When comparing tongue cancer with cN0pN0 vs. pN0pN+ using the total tongue cancer cohort of TCGA, ACTA1 was the only parameter which was associated with hidden lymph node metastasis in T1\/2 (<jats:italic>P<\/jats:italic> = .019). Perineural invasion was significantly associated with high expression of ACTA1 (<jats:italic>P<\/jats:italic>\u2009&lt;\u2009.001). IF and IHC analysis revealed that actin was overexpressed, while E\u2010cadherin and N\u2010cadherin were not significantly
