Summary
Brief summary (as posted)
This multicenter prospective interventional study will evaluate stool and saliva microRNA expression and microbiome composition in patients with histologically confirmed colon or rectal cancer during key phases of the diagnostic and therapeutic pathway. The study aims to confirm and refine molecular signatures associated with colorectal cancer, assess the diagnostic and prognostic potential of salivary biomarkers, and characterize dynamic molecular changes during treatment and follow-up

- type
- EXPERIMENTAL
- label
- Prospective Biomarker Collection Cohort
- description
- Participants with histologically confirmed colon or rectal cancer will undergo protocol-defined longitudinal collection of stool and saliva samples during the diagnostic and therapeutic pathway. At the sponsor center, FFPE tissue and blood/plasma samples may also be collected. Clinical data and diet/lifestyle questionnaire data will be prospectively recorded

- Other: Prospective Biological Sample Collection and Longitudinal Molecular Profiling
- Other: Diet and Lifestyle Assessment
Primary outcomes (4)
- measure
- Diagnostic accuracy of fecal microbiome and fecal microRNA molecular signatures
- timeFrame
- At diagnosis/baseline, before surgery or at least 30 days after bowel preparation for colonoscopy
- description
- Diagnostic performance of predefined and refined fecal microbiome and fecal microRNA signatures, assessed using measures such as sensitivity, specificity, positive predictive value, negative predictive value, and area under the receiver operating characteristic curve for clinically relevant colorectal cancer classifications
