Collecting Blood and Stool Samples to Detect Colorectal Cancer or Precancerous Polyps in Lynch Syndrome Patients, CORAL Study

About the Study

This study will determine the effectiveness of a screening technique, multitarget stool testing, for the detection of colorectal cancer in individuals with . Multitarget stool testing uses stool samples to look for signs of colon cancer. This study will also create a collection of blood and stool samples from individuals with and early onset colorectal cancer (diagnosed younger than 50 years old).

What the Study Involves

Patients will give blood and stool samples no more than 90 days before or between 7-90 days after their routine colonoscopy or flexible sigmoidoscopy (using a flexible tube with a video camera to examine the colon and rectum.). Patients will also give the researchers permission to look at their medical records.
