Volatil Organic Compounds in Exhaled Air and Sweat After Thoracic Surgery for Carcinological Resection (Onco-VOC)

December 17, 2020 updated by: Hopital Foch

Bronchopulmonary cancer, with 39 000 new cases and 30 000 deaths per year, is a main issue in public health in France. It is the leading cause of cancer death in France. A lot of progress in medical care has been made, but surgery remains the most effective treatment, when it is still possible. The goal is to detect and manage the lung cancer as early as possible. Alongside screening strategies by annual thoracic scanner, new approaches with innovative technologies open up for cancer detection and therapeutic follow-up.

The study of volatile organic compounds (VOC) detected in exhaled air or in sweat, is an innovative research area for respiratory diseases. The volatolomic analysis can be done either by the technique of the mass spectrometry which allows the identification of each VOC in the exhaled air or by the technique of electronic nose, simpler and faster, which provides an idea of the general profile of the VOC without identifying them. The VOC have shown their interest in some situations, such as diagnostic or prognostic tool in patients followed for thoracic tumorous pathology or bronchial or pulmonary vascular diseases.

The composition of VOC in exhaled air and sweat is altered in patients with lung cancer. The VOC analysis and their variation could be used particularly in the follow-up of patients treated for lung cancer.

The purpose of this clinical research is to identify the VOCs related to lung cancers by comparing the VOC profiles in exhaled air and in sweat from patients diagnosed with localized lung cancer before and after resection surgery.

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
50

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Comparison of Volatil Organic Compound (VOC) profiles by mass spectrometry
Time Frame: change from baseline profiles at 2 month post-surgery
Comparison of variation in Volatil Organic Compound (VOC) profiles in exhaled air of patients before and after surgery. The VOC will be identified by their molecular mass (by the mass spectrometry)
change from baseline profiles at 2 month post-surgery
Comparison of Volatil Organic Compound (VOC) profiles in by electronic noses
Time Frame: change from baseline profiles at 2 month post-surgery
Comparison of variation in Volatil Organic Compound (VOC) profiles in exhaled air of patients before and after surgery. The VOC will be identified by the sensor deflection (by the electronic noses).
change from baseline profiles at 2 month post-surgery

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
