Methods SABC immunohistochemistry was used to detect the expression of FAK and CD44v6 and analyze the relationship between them. Results The positive expression rate of FAK protein was significantly higher in colorectal carcionma with poor differation， Ducks C+D stages and lymph node metastasis than that with high or moderate differation, Ducks A+B stages and without lymph node metastasis， respectively. FAK expression had no significant correlation with patientrsquo;s age， sex， tumor size and serosa infiltration. The positive expression rate of CD44v6 was significantly higher in the group of serosa infiltration， Duckrsquo;s C+D stages and lymph node metastasis than that of no serosa infiltration， Duckrsquo;s A+B stages and without lymph node metastasis, respectively. There was no significant association with age， sex and tumor differation. There was positive correlation between the expression of FAK and CD44v6(r=0.283，p=0.002. The expression of FAK and CD44v6 was significantly lower in norm
