Volatolomic and Proteomic Profile for Early Diagnosis of Lung Cancer

Volatolomic and Proteomic Profile; Breath, Urine and Serum as Non-invasive Tools for Early Diagnosis of Lung Cancer

The goal of this prospective, case-control study is to discover the specific "omics" biomarkers of early stage of lung cancer using the non-invasive samples (breath, urine and serum) in a total of 200 subjects (100 healthy controls and 100 lung cancer patient). The main questions it aims to answer are:

• Which are the "omics" biomarkers that characterize the early stage of lung cancer?
• How to Translate Laboratory Data into Clinical Data?

For each participant we will collected the breath, urine and blood samples. In lung cancer patients group the samples will be sample before lung cancer resection. The samples of Breath, urine and serum will be analysed using different type of analysis: eNose and the Gas Chromatography combined with Ion Mass Spectrometry (GC/IMS). Moreover, Serum will be analyzed by mass-spectrometry-based proteomics. The purpose of these analyses will be to find biomarkers capable of distinguishing the early-stage of lung cancer from the healthy group. Followup will be performed to evaluate the possible change of the volatolomic and proteomic profile.

All partecipants will sign the Informed Consent before the sampling procedures. In addition, they will complete the clinical questionnaire containing medical history, smoking history and psychological evaluation.We will conduct the trial according to the ICH Good Clinical Practice (GCP) guidelines. Keeping accurate and consistent records is essential to a cooperative study.The IEO Data Management Office will responsible of the study database and data management.

Inclusion Criteria:

1. Lung cancer group

   • Diagnosis of early stage - lung cancer
   • Signed Informed Consent
   • Completed questionnaire

2. Healthy subjects

   • high risk individuals (heavy smokers, subjects with pulmonary disease non-cancer related or with a familiar history of lung cancer disease)
   • Recent (within 6 months) negative Chest X-ray or CT scan

Exclusion Criteria:

Both groups

• No previous chemo or radiotherapy for lung cancer
• No previous malignancies within last 5 years
