Examining exosomes in patients with rectal cancer

Official title: Exosomal as Correlative Biomarker in Clinical Outcomes in Patients Undergoing Neoadjuvant Chemoradiation Therapy for Rectal Cancer

Run by University of Kansas Medical Center · NCT03874559 · Data updated 2026-11-12

This study is trying to see how certain markers in the blood change in people with locally advanced rectal cancer who are getting chemotherapy and radiation, and how these changes relate to their treatment response.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older with a confirmed diagnosis of rectal adenocarcinoma who are set to receive neoadjuvant chemoradiation therapy.

Probably not a fit

Patients under 18, those unable or unwilling to undergo surgery, or with a history of prior pelvic radiation or cancer may not benefit from this study.

What this trial studies

This observational study aims to characterize exosomal biomarker levels in patients with locally advanced rectal cancer who are undergoing neoadjuvant chemoradiation therapy. Participants will receive chemotherapy alongside radiation treatment, with serum samples collected at various stages to analyze exosomal expression. The study will correlate these biomarker levels with clinical and pathologic responses to treatment, utilizing data from medical records and additional analyses in organoid and mouse models of colorectal cancer.

Why it matters

Potential benefit: If successful, this study could lead to improved biomarkers for monitoring treatment response in rectal cancer patients.

How similar studies have gone: While the approach of examining exosomal biomarkers is gaining traction, this specific study's methodology is relatively novel and has not been extensively tested in similar contexts.
