Oral squamous cell carcinoma (OSCC) samples with cervical lymph node metastasis exhibit elevated levels of chemerin, IL-6, interleukin 15 (IL-15), granulocyte macrophage-colony stimulating factor (GM-CSF), regulated upon activation, normal T cell expressed and secreted (RANTES), TNF-α, and vascular endothelial growth factor (VEGF) compared to samples without lymph node metastasis. This evidence concerns the gene IL15 and oral cavity squamous cell carcinoma.
