Previous studies an life style for cotorectal cancer risk suggest that serum lipids and glucose might be related to adenomatous polyps as well as to colorectal carcinogenesis. This case-control study was conducted to investigate the associations between serum lipids, blood glucose, and other factors and the risk of colorectal adenomatous polyp. Male cases with colorectal adenomatous polyp, histologically confirmed by colonoscopy (n=134), and the same number of male controls matched by age for men were selected in hospitals in Seoul, Korea between January 1997 and October 1998. Serum lipids and glucose levels were tested after the subjects had fasted for at least 12 hr. Conditional logistic regression showed that there was a significant trend of increasing adenomatous polyp risk with the rise in serum cholesterol level (p(trend)=0.07). Increasing trend for the risk with triglyceride was also seen (p(trend)=0.01). HDL cholesterol and LDL-cholesterol had increasing trends for the risk, which were not significant. In particular, it was noted that higher fasting blood glucose level reduced the adenomatous polyp risk for men (p(trend)=0.001). This study concluded that both serum cholesterol and triglyceride were positively related to the increased risk for colorectal adenomatous polyp in Korea. Findings on an inverse relationship between serum glucose and the risk should be pursued in further studies.
