ABSTRACT
To explore whether aberrant methylation in the promoter of p16 gene was associated with development and clinicopathological characteristics of colorectal cancer. Methylation-specific PCR(MSP) was used to detect hypermethylation of p16 gene in tumor tissues obtained from 32 patients with colorectal cancer. The results showed that the hypermethylation of p16 promoter was detected in 40.6% of tumor tissues. p16 hypermethylation in patients with Dukes stages of C and D tumors (63%) was higher than that in the stages of A and B tumors (25%). The highly and intermediately differentiated carcinomas had lower positive rate (30%) than the poorly differentiated carcinoma. Furthermore, the hypermethylation of p16 gene in tumor tissue from patients with the lymph node metastasis was different from that without lymph node metastasis (P
