Clinical Trial Summary

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.

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.

Eligibility

Inclusion Criteria:

• Receipt of preoperative colonoscopy

• Receipt of bowel resection; use of adjuvant chemotherapy or radiation therapy as clinically indicated

Exclusion Criteria:

• Stage IV colorectal cancer

• Surgical treatment with subtotal colectomy or total proctocolectomy

• Diagnosis of inflammatory bowel disease (ulcerative colitis or Crohn's disease)

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	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))	at 1 and 4 years
Primary	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))	at 1 and 4 years
Primary	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).	at 1 and 4 years
