Abstract Colorectal cancer is primarily a disease of urban, industrialized societies. In the United States, the lifetime risk for the development of this cancer is approximately 6%. Recent data have suggested that the incidence rates for colorectal cancer may be decreasing gradually in some subgroups of the population.

Prevalence of Colorectal Neoplasms in Asian Americans
Digestive Diseases and Sciences, 2008To determine the yield of colonoscopy in a predominantly Asian American gastroenterology practice in California from 8/2003 to 2/2005.A total 2,723 subjects were included: 87% were Asian and 13% were non-Asian. Advanced neoplasia prevalence was 12% in Asian men and 9% in non-Asian men (P = 0.21), and 8% and 7% in women (P = 0.62).

Chemoprevention of Colorectal Neoplasms
Archives of Surgery, 1986The organospecific, 1,2-dimethylhydrazine-induced rat tumor model was used to test tumor formation in groups of animals receiving regular chow, powdered chow with 7%/wt ascorbic acid supplement, pelleted chow with 1%/wt beta-carotene supplement, and pelleted chow with placebo beadlets. Following a 16-week induction period, animals were killed and tumor

[Screening of colorectal neoplasm].
Der Radiologe, 2009In Germany approximately 29,000 people died of colorectal carcinoma (CRC) in 2002; the risk of getting CRC is 4-6% in Germany, rising with age from the 50th year of life. About one third of all people over 50 years of age have polyps with the potential for malignant transformation in the colorectum, which is a sufficiently high prevalence rate to ...

Dietary Factors Related to Colorectal Neoplasms
Surgical Clinics of North America, 1993Although the etiology of colorectal cancer is multifactorial, experimental evidence suggests a role for dietary factors in the promotion of this disease. The complex interrelations governing energy balance and the consumption of fat, fiber, and micronutrients make it difficult to define the precise role of specific dietary factors in the etiology of ...

Detecting Colorectal Neoplasms
Journal of Clinical Gastroenterology, 1987Because of the controversy surrounding the detection of colorectal neoplasia, I used 10 hypothetical, typical patients to assess the testing attitudes of 33 experienced colonoscopists. There was great disagreement on the type and frequency of the advised diagnostic investigation in some cases.

Harefuah, 1990We screened groups at high risk for colorectal neoplasms, determining the efficacy of the leukocyte adherence inhibition test (LAI) for early detection, in comparison with that of the fecal occult blood (Hemoccult) test and sigmoidoscopy or colonoscopy.

Nonprotruding Colorectal Neoplasms: Epidemiologic Viewpoint
World Journal of Surgery, 2000AbstractHistologic sections from 781 nonprotruding colorectal neoplasias (adenomas and early carcinomas) recorded in Sweden and in Japan were reviewed by the same observer, using strict histologic criteria. Low grade dysplasia (LGD) was present in 82.8% (299/361) of the nonprotruding neoplasms recorded in Sweden but in only 42.6% (179/420) of those ...
