Exploring the role of microbiota in lung cancer treatment

Characterization of Microbiota (intestinal, from Lungs, and Upper Airways) in Patients with Non-small Cell Lung Carcinoma: Exploratory Study

Not applicable Interventional Centre Jean Perrin · NCT03068663

This study is testing how the bacteria in the lungs and throat of patients with non-small cell lung cancer might affect their treatment outcomes when they have surgery alone or surgery with chemotherapy.

What this trial studies

This study investigates the lung and upper airway microbiota in patients with non-small cell lung cancer. It involves two groups: one receiving surgery only and the other receiving both chemotherapy and surgery. Patients will provide various biological samples, including saliva, fecal, and lung tissue, to analyze changes in microbiota and their potential associations. The findings aim to inform future studies on manipulating microbiota to enhance cancer treatment tolerance and effectiveness.

Who should consider this trial

Good fit: Ideal candidates are patients diagnosed with non-small cell lung carcinoma who are eligible for surgery or chemotherapy followed by surgery.

Not a fit: Patients with cognitive difficulties or those currently undergoing treatment with antibiotics, corticosteroids, or immunosuppressants may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment strategies for lung cancer by leveraging microbiota manipulation.

How similar studies have performed: While the role of microbiota in cancer treatment is an emerging field, similar studies have shown promising results in other cancer types, indicating potential for success in this approach.
