Preventive effects of low-dose aspirin on colorectal adenoma growth in patients with familial adenomatous polyposis: double-blind, randomized clinical trial.

There are several reports of clinical trials of aspirin in sporadic colon cancer. However, only one double-blind trial of aspirin in patients with familial adenomatous polyposis (FAP) has been reported to date. This double-blind, randomized, placebo-controlled clinical trial was therefore performed to evaluate the influence of low-dose aspirin enteric-coated tablets (100 mg/day for 6-10 months) in 34 subjects with FAP (17 each in the aspirin and placebo groups).

Excessive fat restriction might promote the recurrence of colorectal tumors.

The incidence of colorectal cancer is rapidly increasing in Japan. This trend has been suggested to be caused by an increasing fat intake as a result of the Westernized diet among Japanese. We investigated whether dietary instruction optimizing the fat energy ratio suppresses the recurrence of colorectal tumors.

Randomized trial of dietary fiber and Lactobacillus casei administration for prevention of colorectal tumors.

The epidemiologic evidence that dietary fiber protects against colorectal cancer is equivocal. No large-scale clinical study of the administration of Lactobacillus casei has been reported. We examined whether dietary fiber and L.

Study of Prevention of Colorectal Cancer through Lifestyle Modification: an Introduction to the Protocol.

Previous epidemiological studies have suggested that lack of exercise and a high fat diet increase the risk of colorectal cancer. We planned a clinical trial to test these propositions, using subjects with multiple colorectal adenomas and/or carcinomas. Enrolment in this study was conducted in two stages.
