About this trial
The purpose of this study is to look at how bacteria present within the stool at the time of surgery and postoperatively may contribute to the development of cancer recurrence after surgery. By collecting stool and blood before and after surgery, the researchers hope to determine if certain types of bacteria, or products that the bacteria produce, promote the development of tumors after surgery. By collecting tumor tissue and growing cell lines, we hope this will help researchers better understand the behavior of these types of tumors.

Trial outcomes
Primary outcomes
Collagenase Activity
Measure collagenase activity present within the stool at the time of surgery to determine if it will be significantly higher in patients who later develop recurrence compared to patients who do not. Assessing further if patients who are the most nutritionally at risk for the development of recurrence will have the highest amounts of bacterial collagenase.
Secondary outcomes
Stool Metagenomics
Assess the correlation of the bacterial community with nutritional intake and the development of colorectal cancer recurrence. Bacterial community analysis will be performed via shotgun metagenomics.
Stool metabolomics
Assess the correlation of the bacterial derived metabolites with nutritional intake and the development of colorectal cancer recurrence. Bacterial community analysis will be performed via short chain fatty acid metabolomics.
Serum Metabolomics
Assess the correlation of the bacterial derived metabolites with nutritional intake and the development of colorectal cancer recurrence. Bacterial community analysis will be performed via short chain fatty acid metabolomics.
