Furthermore, as shown in Table 1, HMGA2 expression strongly correlated with clinical stage (P = 0.001), lymph node status (P = 0.000), histological differentiation (P = 0.002) and survival (P = 0.000) in patients with tongue cancer; however, the analysis data indicated that HMGA2 expression was not correlated with age and tumor stage. This evidence concerns the gene HMGA2 and tongue cancer.
