KRAS is a protooncogene located on the short arm of chromosome 12. The aim of this study was to evaluate the KRAS oncogene and its relationship it with clinicopathologic features in 33 Kurdish patients. Materials and Methods: Metastatic CRC between 2012 and 2016 that came to Imam Reza hospital, Kermanshah province, Iran, were analysed for KRAS mutations using allele specific PCR primers and pyrosequencing. Correlations between variables was analyzed in PASW SPSS and overall survival curves were plotted in Graph Pad prism 5. Results: The mean age for them at diagnosis was 51.512.6 years (range, 2276 years). Among the 33 patients that were sequenced, 12 samples in the KRAS gene had a nucleotide change, 11 in codon 12 and 1 in codon 13.There was no significant relationship between the mutation and clinical and pathological aspects of the disease. Conclusions: Knowledge of the KRAS status can help in decisionmaking to treat metastatic colorectal cancer patients more efficiently and increase survival. However, many Kurdish people due to economic problems are not able to do this valuable genetic test. In addition, we need more careful research of KRAS oncogene at the molecular level in young populations with more patients.
