Abstract

Aim: Pancreatic cancer is a deadly disease, with a mortality rate approximately equal to the incidence rate. One prominent feature of the disease is the high frequency of K-ras mutations, associated with certain risk factors. Since patients are usually observed at an advanced stage, a less invasive screening test, allowing for early diagnosis, would be of great utility. Patients and Methods: Tumour and blood samples of 28 patients with histologically verified pancreatic adenocarcinoma were screened for K-ras mutations and K-ras gene expression. Known risk factors of pancreatic cancer were investigated by a questionnaire. Results: Significant relationships were found between polluted environment and Kras gene mutations, alcohol consumption and codon 61 mutations and coffee consumption and codon 12 mutations. Of interest, meat consumption showed a protective effect against codon 61 mutations. Though K-ras status of the tumour and blood samples were the same in 71.4% of the cases, no significant relationship between the presence of the K-ras mutations and the gene expression were found either in the tumour or the blood samples. Conclusions: Our results indicate that K-ras mutations are often found in blood samples of patients with pancreatic adenocarcinoma. Due to the small number of patients of the present investigations, further studies are required to assess the relevance of our findings for the clinical practice.
