Acerca de la investigación
This pilot study will assess whether a larger study of stool testing for colorectal cancer is practical. It plans to enroll 40 adults born in 1960 or later who have new symptoms that could be related to colorectal cancer. Participants will collect a stool sample at home using a fecal immunochemical test (FIT), complete a questionnaire, and undergo blood tests and colonoscopy as part of their usual medical care. Researchers will compare research FIT results with colonoscopy findings and assess recruitment, sample collection, and completion of study activities. Research FIT results will not routinely be shared with participants or their clinicians. If a research FIT result is abnormal and colonoscopy has not been completed within six months, the study team will notify the primary care provider to encourage colonoscopy follow-up.

This prospective pilot cohort study will evaluate the feasibility of implementing a symptomatic FIT research strategy in the UC San Diego Health system. Recruitment will use electronic health record screening and clinician and patient outreach. Consented participants will provide an at-home stool specimen for research FIT testing and questionnaire data. Usual-care complete blood count, ferritin, and colonoscopy findings will be collected. Feasibility assessments include recruitment, enrollment, stool specimen return, and completion of study activities. Preliminary FIT performance will be assessed against adequate-quality usual-care colonoscopy completed within six months of FIT.
A transition from UCSD laboratory FIT testing to quantitative research FIT testing performed by Polymedco is planned, conditional on IRB approval and execution of the required institutional agreement. Participants using the quantitative FIT kit will mail specimens directly to Polymedco. Specimens and results will be coded by study ID, and the linkage key will remain at UCSD without Polymedco access. The study is supported by a gift from Curebound.
¿Quién podría participar?
La lista siguiente contiene el texto del patrocinador. Puede incluir condiciones, tratamientos previos, resultados de pruebas y otros requisitos. Aparecer en tu búsqueda no significa que califiques.
Inclusion Criteria:
- Adults 18 years or older, born in 1960 or later.
- Newly reported signs or symptoms potentially consistent with colorectal cancer: hematochezia, persistent abdominal pain, altered bowel habits (constipation, diarrhea, or narrow stools), unintentional weight loss greater than 5 pounds, or iron deficiency anemia. Symptoms must not have been reported to the primary care provider before the index visit.
Exclusion Criteria:
- Acute symptoms within 14 days requiring urgent evaluation.
- Up-to-date colorectal cancer screening: colonoscopy within 10 years, sigmoidoscopy within 5 years, FIT within 1 year, or multitarget stool DNA/RNA or cell-free DNA testing within 3 years.
- Prior colorectal cancer, colorectal resection, hereditary colorectal cancer syndrome (including Lynch syndrome or familial adenomatous polyposis), or inflammatory bowel disease.
- Documented infectious cause that clinically explains the symptoms. A negative infectious workup or absence of an infectious workup does not exclude participation.
- Pregnancy.
- Lack of health insurance for usual-care procedures.

Adults with new colorectal cancer-related signs or symptoms
Adults 18 years or older, born in 1960 or later, with newly identified signs or symptoms potentially consistent with colorectal cancer. Participants provide an at-home stool specimen for research FIT testing and complete a questionnaire. Usual-care blood test and colonoscopy findings are collected for comparison.
Diagnostic Test: Quantitative fecal immunochemical test

All enrolled subjects will complete a quantitative immunochemical test and reference colonoscopy

Medidas principales
Enrollment rate
Plazo: From recruitment opening through the end of recruitment, up to 12 months
Percentage of eligible patients approached who provide informed consent and enroll in the study. Calculated as the number enrolled divided by the number of eligible patients approached, multiplied by 100.
Stool sample return rate
Plazo: From enrollment through completion of participant follow-up, up to 6 months
Percentage of enrolled participants who return a stool specimen for research fecal immunochemical testing. Calculated as the number returning a specimen divided by the number enrolled, multiplied by 100.
Completion of study activities
Plazo: From enrollment through completion of participant follow-up, up to 6 months
Percentage of enrolled participants completing each planned activity: research stool specimen collection, study questionnaire, usual-care blood testing, and usual-care colonoscopy. Completion percentages will be reported separately for each activity, using all enrolled participants as the denominator.
Medidas secundarias
Advanced neoplasia
Plazo: At time of colonoscopy completed within 6 months of FIT.
Proportion of patients with advanced neoplasia (advanced adenoma, advanced serrated polyp, or colorectal cancer) at time of colonoscopy.
Sensitivity for advanced neoplasia
Plazo: At time of colonoscopy completed within 6 months of FIT.
Proportion of people with advanced neoplasia who have an abnormal FIT (defined at a 4 nanogram/g feces cutoff) . Denominator = # of people with advanced neoplasia; Numerator = # of people with an abnormal FIT
Specificity for advanced neoplasia
Plazo: At time of colonoscopy completed within 6 months of FIT.
Proportion of people without advanced neoplasia who have normal FIT (defined at below a 4 nanogram/g feces cutoff) . Denominator = # of people without advanced neoplasia; Numerator = # of people with a normal FIT
