Examining neutrophil characteristics in lung cancer patients

Studies of Phenotypic and Functional Characteristics of Circulating Neutrophil Subpopulations in Patients With Lung Cancer Undergoing Treatment

Observational Assistance Publique - Hôpitaux de Paris · NCT06244355

This study is testing whether certain types of white blood cells in lung cancer patients can help predict how well they will respond to treatment.

What this trial studies

This study aims to investigate the phenotypic, functional, and metabolomic characteristics of circulating neutrophil subpopulations in patients with metastatic non-small cell lung cancer (NSCLC). Blood samples will be collected from lung cancer patients before their first treatment and during their first evaluation visit, and compared to samples from healthy volunteers. The researchers hypothesize that distinct neutrophil subpopulations may play a role in tumor progression and resistance to immunotherapy, potentially serving as predictive biomarkers for treatment response.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with a diagnosis of metastatic lung cancer who have not yet received treatment.

Not a fit: Patients with active infections, previous chemotherapy, or those who are pregnant or under guardianship may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to the identification of biomarkers that predict response to immunotherapy in lung cancer patients.

How similar studies have performed: While the role of neutrophil subpopulations in cancer is being explored, this specific approach to studying their characteristics in lung cancer is relatively novel.
