Multi-marker Stool Test for Detection of Colorectal Neoplasia: Marker Panel Selection and Technical Development Studies

Patients who have been recently diagnosed with colo-rectal cancer or pre-cancer will be
asked to submit a stool sample(s)(at least 7 days AFTER colonoscopy) and will have the
option of submitting blood and tissue samples for future colo-rectal cancer-related test

Inclusion Criteria:

1. Subject is male or female, 40-90 years of age, inclusive.

2. Subject has a diagnosis of CRC, at any stage, confirmed with a tissue biopsy and/or
≥1 cm colorectal polyp/adenoma/mass identified on a colonoscopy that is of sufficient
size to require surgical excision or complex colonoscopic polypectomy.

3. Subject understands the study procedures and is able to provide informed consent to
participate in the study and authorization for release of relevant protected health
information to the study Investigator.

Exclusion Criteria:

1. Subject has active synchronous extra-colonic aerodigestive tract cancers (e.g., lung,
esophagus, stomach, or pancreatic cancer).

2. Subject has a history of any inflammatory bowel disease.

3. Subject has familial adenomatous polyposis, hereditary non-polyposis colorectal
cancer (Lynch) syndrome, or other hereditary cancer syndromes.

4. Individual has a condition the Investigator believes would interfere with his or her
ability to provide informed consent, comply with the study protocol, which might
confound the interpretation of the study results or put the person at undue risk.
