title: SDF-1 and CCR5 genes polymorphism in patients with head and neck cancer.
abstract: The frequency of SDF1-3'A and CCR5Delta32 in patients with head and neck cancer were determined in this study. The frequencies of alleles and genotypes of SDF-1 and CCR5 were assessed by PCR method in 156 patients with malignant head and neck cancer, 125 (80.1%) cases with squamous cell carcinoma and 31 (19.9%) cases with salivary gland tumors and compared with 262 age-sex matched healthy control individuals. SDF-1 genotypes in patients with SCC of head and neck, but not with salivary gland tumors, showed a statistically significant difference compared to the normal group (P < 0.005 for SCC and P = 0.3 for salivary gland tumors). There were no significant differences in the frequencies of SDF1-3'A allele, CCR5 genotypes and alleles between patients and controls. Based on the present study SDF1-3A may be associated with the susceptibility of patients to SCC of head and neck cancer.
