BACKGROUND: To date, EGF 61*A/G, TGF-β1 -509*T/C and TNF-α -308*A/G gene polymorphisms have been not been analysed in pancreatic carcinoma. This study investigated the frequency of these gene polymorphisms among patients with cancer of the pancreatic head. PATIENTS AND METHODS: A total of 73 pancreatic head cancer patients and 117 cancer-free healthy people were recruited at the Surgical Department of the University Hospital Mannheim. Genomic DNA was isolated from peripheral blood and gene polymorphisms were analysed by PCR-RFLP. RESULTS: The distribution of EGF 61*G/G homozygotes among pancreatic head cancer patients was more frequent than that in the control group (24.7% vs 11.1%, odds ratio (OR) = 2.618, 95% confidence interval (CI) = 1.195-5.738). In addition, the frequency of the G allele in the pancreatic head cancer patient group was also higher than that in the control group (45.9% vs. 33.3%, OR = 1.696, 95% CI = 1.110-2.592). No difference was found for the TGF-β1 -509 and TNF-α -308 genotypes among pancreatic head cancer patients and healthy controls. CONCLUSION: The frequencies of the EGF 61*G/G genotype and G allele are significantly increased among patients with pancreatic head cancer. TGF-β1-509*T/C and TNF-α -308*A/G gene polymorphisms are not related to this cancer entity.
