Genetic variants in cytokine and metastatic potential genes included in the current study.

ap-value of the Hardy-Weinberg equilibrium testing for genotypes evaluated in the entire study population.*marks genotype distributions which did not meet HWE, later removed from analyses.Abbreviations used for cytokines and metastasis-associated gene variants: IFN-γ – interferon-γ; IL: various interleukins; TNF – tumor-necrosis factors; TGF-β1 – transforming growth factor-beta-1; IGF-2R – insulin-like growth factor 2 receptor; MMP-1 – matrix metalloproteinase 1.
