In clinicopathological characteristics, we determined that the expression level of miR-455-5p was positively correlated with the N stage of OSCC patients, and patients with low MAP17 expression exhibited more lymph node metastasis, LVI, or clinical poor risk factors for recurrence (Supplementary Table 1). This evidence concerns the gene PDZK1IP1 and metastatic malignant neoplasm in the lymph nodes.
