Circulating and Imaging Biomarkers to Improve Lung Cancer Management and Early Detection

Conditions
Lung Cancer
Interventions
Other: LDCT (Low Dose CT)
Registration Number
NCT04315753
Lead Sponsor
Istituto Clinico Humanitas
Brief Summary

Validation of biomolecular markers in the circulation and radiomic features are the focus of this project.The aim is to assess the role of molecular and cellular biomarkers (exosomes antigens, Circulating tumor cells - CTCs, panel of mutations in circulating free DNA) and radiomic signature, as complementary to assist early detection of lung cancer by LDCT.

Arm && Interventions
GroupInterventionDescription
prospective screening cohort of high risk individualsLDCT (Low Dose CT)a prospective screening cohort of high risk individuals enrolled at Humanitas Hospital (1000) will allow to recruit 50 patients with screening detected lung cancer and a large number of negative controls. Analysis of CTC, exosome antigens and cfDNA mutation profile will be performed.
Primary Outcome Measures
NameTimeMethod
Obtaining biological samples, and correspondent clinical and imaging data to use, as fresh blood tissues or frozen stored tissues from lung cancer patients and controls obtained from the Division of Thoracic Surgery and LDCT lung-cancer screening program01 Jan 2018 - 01 Jan 2023

1.1 : Obtaining biological material from cancer cases and controls (clinical cases) and store in the biobank with clinical data and imaging for bio radiomic analysis.

1.2 : Identification and testing of methods of recruiting high-risk individuals for a lung-cancer screening program using available database to select very high risk individuals; 1.3 : Obtaining biological material from asymptomatic screening-detected cancer cases and controls and store in the biobank with clinical data and imaging.

1.4 : Assessment of compliance of the recruited population and assessment of mean lung-cancer risk. Verify the potential impact of molecular markers as a pre-screening test to better assess the risk of subjects, evaluate the impact on nodule management and number of false positive cases among screening process according to biostatistical analysis.

Secondary Outcome Measures
NameTimeMethod
Tumor antigens identified by RPPA in lung cancer circulating exosome01 Jan 2018 - 01 Jan 2023

Blood-derived exosomes will be collected. Exosome antigens assessment will be performed. Then, a bioinformatics analysis of the performance of exosome antigens as diagnostic markers for lung cancer will be performed.

Investigate the potential role of CTCs as diagnostic and prognostic tool in a screening content01 Jan 2018 - 01 Jan 2023

3.1 Samples collection and preparation: isolation and count of CTCs; 3.2 Evaluation of diagnostic role of CTCs in early stage lung cancers; 3.3 Evaluation of the prognostic value of the number of CTCs at diagnosis (measured in terms of "progression free survival" and "overall survival"); 3.4 Characterization of CTCs for the expression of EMT and correlation with angiogenesis pattern of primary tumor; 3.5 Biostatistical analysis of the results.

Development and validation of a panel of mutations on circulating DNA as diagnostic test for lung cancer.01 Jan 2018 - 01 Jan 2023

4.1 Samples collection and library preparation; 4.2 Standardisation of the technique; 4.3 Assessment of diagnostic role of the protein signature; 4.4 Bioinformatics analysis of the performance of the cell free DNA mutation signature as diagnostic tool for lung cancer

Investigate a radiomic signature to discriminate malignant lung nodule Background01 Jan 2018 - 01 Jan 2023

5.1 assess the association of imaging features with clinical data and histology; 5.2 Identification the radiomic signature, the combination of imaging features, able to characterize lung lesions; 5.3 Validation of the signature on a new subset of patients; 5.4 Assessment of the role of radiomic signature, together with circulating markers in predicting lung malignancy
