A Multicenter, Placebo-controlled Clinical Study of Berberine Hydrochloride in Preventing Recurrence and Carcinogenesis After Endoscopic Removal of Colorectal Adenomas: 6-year Retrospective Follow-up Data

What this Trial Is About

Colorectal cancer is a common and serious disease that often develops from precursor growths called adenomatous polyps. This study evaluates the long-term effects of berberine hydrochloride, a drug previously shown to reduce recurrence of these polyps after removal. Researchers aim to see if the protective effects of berberine continue for up to six years after patients stop taking the medication. The study observes patients who were part of an earlier trial where they received either berberine or a placebo. It compares the recurrence rates of colorectal adenomas and other types of polyps at multiple intervals: within the first year, between one and three years, and between three and six years after stopping the drug. This retrospective follow-up helps assess berberine's long-term preventive effects. Participants will be monitored through medical records to track the recurrence of colorectal adenomas and other polyps over six years. Researchers will analyze outcomes such as the rate of traditional adenoma recurrence and the incidence of hyperplastic and serrated polyps. This study provides important information about the lasting impact of berberine on colorectal polyp recurrence after endoscopic removal.
