K-ras gene mutation as an early prognostic marker of colon cance

Languages of publication
Due to increased colorectal cancer incidence there is a necessity of seeking new both prognostic and prediction factors that will allow to evolve new diagnostic tests. K-ras gene seems to be such a factor and its mutations are considered to be an early marker of progression of colorectal cancer. The aim of the study was to find a correlation between K-ras gene mutation in patients with diagnosed colorectal cancer and selected clinical parameters. Material and methods. A total of 104 patients (41 women and 63 men) with diagnosed colorectal cancer were included in this study. The average age of male group was 68.3 and in female group – 65.9. Samples were taken from paraffine blocks with tissue from diagnosed patients and K-ras gene mutation were identified. Afterwards the statistical analysis was made seeking the correlation betweenK-ras gene mutation incidence and clinical TNM staging system, tumour localisation, histological type, sex, age. Results. K-ras gene mutations were detected in 20.1% of all colorectal cancers. Significantly higher rate of K-ras gene mutations were diagnosed among patients classified at stage I (40%), stage IIC (50%) and stage IV (50%) according to the TNM classification. Conclusions. The results of our study are compatible with other studies and indicate the correlation between K-ras gene mutation and colorectal cancer incidence. Identification of K-ras gene mutation may complement other diagnostic methods at early stage of colorectal cancer.
