Evaluating immune cell characteristics in patients with non-metastatic rectal cancer

Official title: Prospective Monocentric Study Evaluating the Circulating NK Cells Phenotype and the ImmunoScore® in Patients With Non Metastatic Rectal Adenocarcinoma Treated With Preoperative Radiochemotherapy With or Without Initial Chemotherapy

Run by Institut Sainte Catherine · NCT06536127 · Data updated 2026-11-12

This study is testing how certain immune cells in the blood of patients with non-metastatic rectal cancer respond to treatment to see if they can help improve care and outcomes.

Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are adults aged 18 and older with histologically confirmed adenocarcinoma of the rectum who are scheduled to receive specific chemoradiotherapy treatments.

Probably not a fit

Patients with metastatic or unresectable disease will not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study focuses on assessing the phenotype of circulating natural killer (NK) cells and the ImmunoScore® in patients diagnosed with non-metastatic rectal cancer. Participants will undergo standardized chemoradiotherapy treatment, and blood samples will be collected to analyze immune responses. The study aims to understand the relationship between immune cell characteristics and treatment outcomes, potentially guiding future therapeutic strategies. By evaluating these immune parameters, the research seeks to improve patient management and treatment efficacy.

Why it matters

Potential benefit: If successful, this study could enhance the understanding of immune responses in rectal cancer, leading to improved treatment strategies and better patient outcomes.

How similar studies have gone: While this approach is innovative, similar studies evaluating immune cell characteristics in cancer have shown promising results, suggesting potential for success.
