Using Infrared Spectroscopy to Analyze Volatile Organic Compounds (VOCs) in the Breath of Patients With Lung Cancer

May 29, 2024 updated by: Picomole Inc

The goal of this clinical trial is to compare breath samples from patients with lung cancer, those with stable lung nodules, and individuals without lung cancer. The main questions it aims to answer are whether breath patterns are different in these groups and to see if breath patterns change after treatment in patients with lung cancer.

Participants will be asked to provide one breath sample, and two if they get treated. They will also be asked to fill out a questionnaire about their background and medical history.

Detailed Description

Globally, lung cancer accounts for the most cancer deaths in both sexes combined. It is believed to develop slowly through progressive accumulation of genetic mutations, hence the disease allows time for diagnosis and curative surgical treatment. Five year survival rates for non-small-cell lung carcinoma (NSCLC) can range from 57-61% when detected in the early stages of disease. This is compared with a survival rate of approximately 6% once distant metastases are present. However, disease diagnosis typically occurs when it has progressed to an advanced stage when patients present with signs and symptoms. Therefore, technologies capable of asymptomatic disease detection will significantly impact lung cancer specific mortality. Metabolomic profiling of cancer measures compounds produced as a result of cellular activity including volatile organic compounds (VOCs) in exhaled breath. Infrared spectroscopy is a proven technique for breath analysis that can measure chemical concentrations in the parts per trillion range for certain VOCs. When coupled with machine learning techniques, this has the potential to be a novel approach for disease detection using exhaled breath.

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.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

Yes

Sampling Method

Non-Probability Sample

Study Population

Study participants in all cohorts must meet lung cancer screening criteria as defined by the PLCOm2012 and/or US Preventative Services Task Force (USPSTF) risk criteria. This study will enroll 30 patients from 3 different cohorts (confirmed NSCLS, stable pulmonary nodules, screened and negative controls). Additionally, a second breath sample may be taken from the 30 patients with lung cancer, totalling up to 120 breath samples.

Description

Inclusion Criteria:

Study participants in the lung cancer and control cohorts must meet lung cancer screening criteria as defined by the PLCOm2012 and/or US Preventative Services Task Force (USPSTF) risk criteria.

Exclusion Criteria:

  • Patients are not eligible if they are currently receiving treatment for lung cancer.
  • Patients are not eligible for a second breath sample if it has been less than 6 months since last application of treatment.

Note: Breath sampling technology is sensitive to chemicals produced by tobacco, cannabis and e-cigarettes as well as alcohol (consumed by the subject or used by the operator around the equipment). We ask participants to refrain from:

  • Smoking (tobacco, cannabis or e-cigarettes) at least 4 hours before breath sampling;
  • Consume alcohol (including mouthwash) at least 8 hours before breath sampling.

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Confirmed Lung Cancer

To be eligible for the lung cancer group:

  • Aged 50 and over;
  • Current or former smoker with smoking history ≥ 20 pack-years;

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
Differences in Breath Spectra of Lung Cancer, Stable Pulmonary Nodules, and Controls
Time Frame: 2 years
Using infrared cavity-ringdown spectroscopy, breath spectra of volatile organic compounds (VOCs) will be measured. Breath spectra will be statistically analyzed to identify features specific to each of the respective cohorts. These features will be used to train mathematical and statistical models to differentiate and categorize the samples within the three cohorts.
2 years

Secondary Outcome Measures

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.
Outcome Measure
Measure Description
Time Frame
Differences in breath spectra of patients with lung cancer before and after treatment
Time Frame: 2 years
Using infrared cavity ring-down spectrometry, breath samples will be taken from individual patients before and after surgical resection of the tumour. The objective is to identify and measure intra-patient differences in respiratory profiles before and after treatment.
