Oral squamous cell carcinoma (OSCC) is the most common cancer of oral cancers. Recent data suggest that chemokines could be essential players in carcinogenesis and that tumor cells express chemokine receptors and use chemokines to metastasize to the target organ in many malignancies in humans. The aim of this study was to test the hypothesis that expression of SNPs in chemokine, CXCL1 and CXCL2 correlates with oral squamous cell carcinomas in Korean population. The CXCL1 and CXCL2 genotypes were determined in 21 subjects with oral squamous cell carcinoma and 90 control subjects without oral squamous cell carcinoma. The genotypes were determined by direct sequencing. The genotype distribution and allele frequency within the OSCC patients were not significantly different from those of control subjects. But among OSCC subjects, there was significant difference of CXCL1 gene in the degree of nuclear aberration. These findings suggest that CXCL1 -442C/T polymorphism and CXCL2 -264T/C polymorphism are not related to the development of OSCC but polymorphism of CXCL1 gene might have a relation with progression of OSCC in Korean population.
