Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The subject is to study the lung microbiota and the one of upper airways (UAs) (much less studied than the intestinal microbiota) in 40 patients having lung cancer. 20 patients undergo only surgical treatment, while other half receives also chemotherapy. The idea is to explore changes in microbiota of the lung, upper UAs and intestine, and potentially find associations between them. These results will serve us as a base for the future study, focused on manipulation of the microbiota by prebiotics, probiotics or symbiotics and its effect on anti-cancer treatment tolerance and effectiveness.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Lung cancer patients will be divided in two groups, a first one with patients undergoing both chemotherapy and surgery (Pct-chir), and the second one with patients only undergoing surgery (Pchir). Following inclusion, they will be given a 7-days alimentary survey, along with blood and saliva sampling (after buccodental examination and dental panoramic). The Pct-chir group will repeat the same procedure after the chemotherapy and before the surgery.

Day before the surgery, patients are asked to bring their faecal samples (in special box provided in advance) and the filled survey. During the operation the piece of lung tissue as well as the tumour (if the size enables it) will be sampled for further analysis. Lavage will be performed on the lung immediately after its resection.

Saliva, faecal sample, lung and tumour tissue, and lavage will be used for bacterial DNA extraction, followed by qPCR and sequencing analysis.

Lavage and blood samples will be analysed by flow cytometry and ELISA, to establish the immunological profile (interleukines, cell surface markers).

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

NON_RANDOMIZED

Intervention Model

PARALLEL

2 groups of patients will be follow :

* Pchir : Non small cell lung carcinoma patients with an indication of immediate surgery.
* Pct-chir : Non small cell lung carcinoma patients with an indication of neoadjuvant chemotherapy before the surgery.
Primary Study Purpose

OTHER

Blinding Strategy

NONE

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Pchir

Non small cell lung carcinoma patients designated for immediate surgery. Intervention in this group is "sampling". The sampling will be done for:

* blood and saliva: at consultations after inclusion in the study
* faeces: day before the surgery
* lung/tumour tissue, bronchoalveolar lavage: during surgery after lobectomy

Group Type EXPERIMENTAL

Sampling

Intervention Type OTHER

Patients will receive their standard treatments, surgery with/without chemotherapy. A patient intervention consists in taking samples of blood, saliva, faeces, lung/tumour tissue, and bronchoalveolar lavage fluid.

Pct-chir

Non small cell lung carcinoma patients who will receive neoadjuvant chemotherapy before the surgery. Intervention in this group is "sampling". The sampling will be done for:

* blood and saliva: 1st time at consultations after inclusion in the study, 2nd time at consultations after chemotherapy and before surgery
* faeces: 1st time the day before the chemotherapy, 2nd time the day before the surgery
* lung/tumour tissue, bronchoalveolar lavage: during surgery after lobectomy

Group Type EXPERIMENTAL

Sampling

Intervention Type OTHER

Patients will receive their standard treatments, surgery with/without chemotherapy. A patient intervention consists in taking samples of blood, saliva, faeces, lung/tumour tissue, and bronchoalveolar lavage fluid.
