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

1

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.

Time frame
From Enrollment to 12 months postoperative.

Secondary outcomes

1

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.

Time frame
From Enrollment to 12 months postoperative.
2

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.

Time frame
From Enrollment to 12 months postoperative.
3

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.

Time frame
From Enrollment to 12 months postoperative
