Understanding biomarkers in metastatic colorectal cancer treatment

On-treatment Biomarkers in Metastatic Colorectal Cancer for Life: The On-CALL Study

Region Skane · NCT05755672

This study is trying to see how cancer changes during treatment in people with metastatic colorectal cancer and whether certain genetic markers can help tailor better treatment options for them.

What this trial studies

The On-treatment biomarkers in metastatic ColorectAL cancer for Life (On-CALL) study aims to explore the evolutionary progression of metastatic colorectal cancer (mCRC) during treatment. This prospective observational study will analyze genetic heterogeneity across different metastatic sites and assess the role of circulating tumor DNA (ctDNA) as a biomarker for treatment response. By examining the tumor microenvironment and immune cell interactions, the study seeks to uncover mechanisms behind therapeutic failures in mCRC patients. The findings could lead to more personalized treatment strategies for patients undergoing chemotherapy and surgical interventions.

Who should consider this trial

Good fit: Ideal candidates for this study are patients diagnosed with synchronous metastatic colorectal cancer who are planning to undergo treatment with curative intent.

Not a fit: Patients who do not meet the inclusion criteria or are not willing to provide informed consent may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance personalized treatment approaches for patients with metastatic colorectal cancer, potentially improving survival outcomes.

How similar studies have performed: Other studies have shown promise in understanding tumor heterogeneity and biomarkers in cancer treatment, suggesting that this approach could yield valuable insights.
