KRAS Gene Mutations and Gender Differences in Colorectal Cancer

The aim of this study was to investigate the frequency and spectrum of KRAS mutations in men and women with colorectal cancer (CRC), and an impact of KRAS-mutation status on the clinical and morphological features of CRC. The study included 303 patients (168/55.4% women and 135/44.6% men) with CRC T...

Description
Summary:The aim of this study was to investigate the frequency and spectrum of KRAS mutations in men and women with colorectal cancer (CRC), and an impact of KRAS-mutation status on the clinical and morphological features of CRC. The study included 303 patients (168/55.4% women and 135/44.6% men) with CRC T2-4N0-2M0-1. We defined 7 KRAS SNP-mutations (G12D, G12A, G12R, G12C, G12S, G12V and G13D) located within codons 12 and 13 using Bio-Rad real-time thermal cyclers CFX96 and Real-Time-PCR- KRAS-7M Kit. The frequency of KRAS mutations was 35.6% in the CRC patients with a predominant presence of G>A transitions. The KRAS codon 12 and 13 mutations are predictive of poor prognosis The KRAS-mutated CRC has clinical features in view of the gender differences. KRAS-mutation status is a promising predictive biomarker of personalized treatment.
