Investigating blood-based biomarkers in rectal cancer treatment

Timing To Minimally Invasive Surgery After Neoadjuvant Chemoradiotherapy For Rectal Cancer: A Multicenter Randomized Controlled Trial - Biomarkers SubStudy

Observational Azienda Ospedaliera SS. Antonio e Biagio e Cesare Arrigo di Alessandria · NCT03962088

This study is testing if certain tiny molecules in the blood can help track how well treatment is working for people with locally advanced rectal cancer.

What this trial studies

This observational study focuses on patients with locally advanced rectal cancer undergoing neoadjuvant chemoradiotherapy followed by surgery. It aims to identify microRNAs as potential blood-based biomarkers to monitor tumor response, addressing the need for valid biomarkers due to the heterogeneous response to treatment. By analyzing blood samples, the study seeks to provide a less invasive and more comprehensive method for assessing tumor sensitivity compared to traditional tissue biopsies. The research will involve extensive histopathological work-up of tumor specimens post-surgery to correlate with blood biomarker findings.

Who should consider this trial

Good fit: Ideal candidates include adults over 18 with histologically-proven adenocarcinoma of the rectum who are eligible for neoadjuvant chemoradiotherapy and subsequent surgery.

Not a fit: Patients with metastatic disease or those unable to complete neoadjuvant treatment may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved monitoring of treatment response in rectal cancer patients, allowing for more personalized treatment approaches.

How similar studies have performed: While there have been studies investigating tissue-based biomarkers, the exploration of blood-based microRNAs as biomarkers in this context is relatively novel.
