Summary
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.
