ABSTRACT
<p><b>OBJECTIVE</b>To explore the distribution of HER-2 genetic polymorphism at codon 655 and its association with susceptibility of colorectal cancer in Chinese.</p><p><b>METHODS</b>A population-based case-control study was carried out. 292 patients with colorectal cancer and 842 healthy controls were interviewed. Meanwhile, the genetic polymorphism of HRE-2 was detected using polymerase chain reaction-restriction fragment length polymorphism.</p><p><b>RESULTS</b>The frequencies of Ile/Val+Val/Val genotypes and Val allele were both higher in cases (25.34% and 13.36%) than those in controls (18.41% and 9.74%) (P<0.05). Compared with Ile/Ile genotype, Ile/Val+Val/Val genotypes were significantly associated with colorectal cancer [ORadjusted=1.54, 95% CI 1.11-2.14]. The adjusted odds ratio of interactions between this polymorphism and smoking, alcohol drinking were 1.43 (95%CI 0.88-2.30) and 1.29 (95%CI 0.73-2.29), respectively.</p><p><b>CONCLUSION</b>The present findings suggest that HER-2 genetic polymorphism at codon 655 may be associated with the risk of colorectal cancer in Chinese. In addition, there are no interactions between this polymorphism and smoking, alcohol drinking, respectively.</p>
