Blood test using circular RNAs for early detection of colorectal cancer

Liquid Biopsy for Early Detection of Colorectal Cancer Using Circular RNA

City of Hope Medical Center · NCT07224789

This project tests whether a blood test that measures circular RNAs can detect early-stage colorectal cancer in adults with newly diagnosed (stage I–III) disease.

What this trial studies

This observational project collects pre-treatment plasma from adults with histologically confirmed stage I–III colorectal cancer at City of Hope to profile cell-free circular RNAs (cf-circRNAs). Researchers will isolate cf-circRNAs from plasma and quantify them using RT-qPCR and next-generation sequencing to identify tumor-associated signatures. The team aims to develop a minimally invasive liquid biopsy assay that could complement colonoscopy and stool-based tests. Diagnostic performance will be compared to clinical and pathological tumor data.

Who should consider this trial

Good fit: Adults aged 18 or older with histologically confirmed stage I–III colorectal cancer who can provide pre-treatment plasma samples and informed consent are ideal candidates.

Not a fit: People without colorectal cancer, those with stage IV disease or other recent active malignancies, or those unable to provide good-quality pre-treatment plasma samples are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, this could produce a sensitive, minimally invasive blood test that helps detect colorectal cancer earlier and broadens screening options for patients.

How similar studies have performed: Early research has shown promising signals that cell-free circular RNAs can reflect tumor presence, but large clinical validation for colorectal cancer detection remains limited.
