Cancer and adenomatous polyp distribution in the colorectum
1Department of Surgery II, Faculty of Medicine, Kyushu University, Fukuoka, Japan.
Objective:
To examine the possible role of adenomatous polyps in colorectal cancer development, this study focused on the relationship of the distribution between adenomatous polyps and cancer in the colorectum.
Methods:
The distribution of 753 adenomatous polyps was compared with that of 35 colorectal cancer lesions in 510 male patients ranging from 45 to 55 yr of age who underwent a total colonoscopy.
Results:
The incidence of cancer significantly increased with a distal shift in the colorectal sites in comparison with that of adenomatous polyps (p < 0.02).
Conclusion:
The different distribution between adenomatous polyps and cancer thus suggested that adenomatous polyps at various colorectal sites appear to have a different malignant potential for cancer development.
