Abstract：
BACKGROUND:Colorectal carcinomas were studied regarding early proof of liver metastases through determination of K-ras mutations. PATIENTS AND METHODS:Seventy-seven colorectal carcinomas were investigated for the presence of point mutations in codon 12 and 13 of the K-ras gene, using single-strand conformation polymorphism (SSCP) analysis and direct sequencing. RESULTS:Twenty-six carcinomas were positive for K-ras mutations, of which 21 had codon 12 and 5 had codon 13 mutations. Twenty patients with K-ras-positive tumor (20 out of 26: 77%) developed liver metastases, of which 13 had simultaneous metastases and 7 had metachronous metastases. There was a significant association between K-ras mutations and liver metastases (p=0.03). A multivariate logistic regression model demonstrated that the involvement of lymph node (p<0.01) and K-ras mutations (p=0.02) were predictive factors for liver metastases from colorectal carcinoma. Sequencing in carcinomas without liver metastases showed the base change in the first position of codon 12, whereas with liver metastases it showed significantly frequent base change in the second position of codon 12 (p<0.01). CONCLUSION:It is suggested that the presence of K-ras mutation, especially base change in the second position of codon 12, may predict liver metastases from colorectal carcinoma.
