Title
The association of the sulfur microbial diet with colorectal adenoma and recurrent adenoma risk in the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial
Summary
Colorectal cancer (CRC) is the third most common and third deadliest form of cancer in the United States. Diet has received increasing attention in recent years as an important means of cancer prevention. And some specific dietary patterns will produce hydrogen sulfide, a gastrointestinal carcinogen that is difficult to directly measure, through gastrointestinal microorganisms. Recently, related studies have established a sulfur microbial diet score and confirmed that it is positively correlated to colorectal cancer and colorectal adenomas(1-3). However, due to population constraints, the correlation between sulfur microbial diet scores and colorectal adenomas in people over 50 years of age has not been confirmed(3). We will further optimize the sulfur microbial diet score by analyzing the existing sulfur microbial diet score composition, combined with the specific role of diet composition in colorectal cancer. And use data such as DQX, SCU, and BQ in the PLCO database to explore the specific association of sulfur microbial diet scores with the incidence of adenoma and recurrent adenoma in people older than 50 years of age.
