Our study shows that IHC expression of ELOVL6 in 71 OSCC patients was only correlated with TNM stage, whereas no statistically significant differences were observed in patient sex, age, tumour location, tumour size, lymph node metastasis, or vascular and perineural invasion (Table 4). Here, ELOVL6 is linked to metastatic malignant neoplasm in the lymph nodes.
