  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: Participants who are diagnosed with stage I-III colorectal cancer. All participants who are within 1 year of colon cancer resection will be asked to participate in the study.

Who may be able to join

  • Diagnosis of stage I, II or III adenocarcinoma of the colon or rectum
  • Receipt of preoperative colonoscopy
  • Receipt of bowel resection; use of adjuvant chemotherapy or radiation therapy as clinically indicated

Who cannot join

  • Stage IV colorectal cancer
  • Surgical treatment with subtotal colectomy or total proctocolectomy
  • Diagnosis of inflammatory bowel disease (ulcerative colitis or Crohn's disease)
  • Diagnosis of polyposis syndrome including Lynch syndrome or familial polyposis
  • Presence of advanced adenomas (1 cm or larger, villous features and/or high grade dysplasia) that were not removed at the preoperative colonoscopy or contained in the resection specimen.
  • Inability to provide informed consent
  • Inability to understand spoken and written English
  • Medical comorbidities that would be contraindications to sedation or that would preclude any benefit of routine surveillance post-resection. These would be at the discretion of the participant's providers.

About this study

The purpose of this research study is to determine whether testing of stool for a panel of markers will enable us to detect polyps and cancer compared to standard testing.

Read the detailed description

Participants who were diagnosed with Stage I-III colorectal cancer will undergo testing with mt-sDNA followed by a questionnaire about satisfaction with mt-sDNA (multitarget stool DNA panel), prior to their scheduled colonoscopies at years 1 and 4 after diagnosis.

Participants will be asked to provide a stool sample for mt-sDNA (Cologuard) testing that will be collected within 90 days before their scheduled colonoscopy. The kit will be given to the participant by study personnel and mailed back directly to Exact Science.

Medical subject headings
Colonic Neoplasms, Rectal Neoplasms, Colorectal Neoplasms

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Sensitivity of mt-sDNA compared to Colonoscopy

    Compare the results between mt-sDNA (categorized as a single positive or negative result) with the findings at colonoscopy, the "gold standard". Colonoscopy will be considered positive if an adenoma or carcinoma is found and otherwise negative.

    Sensitivity is defined as True Positive (TP)/(TP+ False Negative (FN))

    Measured: at 1 and 4 years

  2. Specificity of mt-sDNA compared to Colonoscopy

    Compare the results between mt-sDNA (categorized as a single positive or negative result) with the findings at colonoscopy, the "gold standard". Colonoscopy will be considered positive if an adenoma or carcinoma is found and otherwise negative.

    Specificity is defined as True Negative (TN)/(TN+ False Positive (FP))

    Measured: at 1 and 4 years

  3. Participant acceptance of mt-sDNA as a follow up strategy compared to colonoscopy as measured by the Stool Test Satisfaction Survey.

    Participant acceptance as measured by the Stool Test Satisfaction Survey, which includes 14 questions scored on a Likert scale. Possible scores ranging from 14 - 70, with higher scores indicating better outcomes.

    Responses will be grouped based on the distribution, but most likely as 1-2 (neutral, unfavorable or least favorable ) versus 3-5 (most favorable or very favorable).

    Measured: at 1 and 4 years

Questions about this trial

What is this clinical trial studying?

An observational study of Adenocarcinoma of the Colon and Adenocarcinoma of the Rectum, run by Case Comprehensive Cancer Center at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 9 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Gregory Cooper, MD (1-800-641-2422, gregory.cooper@uhhospitals.org), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Sensitivity of mt-sDNA compared to Colonoscopy (time frame: at 1 and 4 years). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Apr 2026.
