CLEARLY: Validation of Multiparametric Models and Circulating and Imaging Biomarkers to Improve Lung Cancer EARLY Detection.
Study Details
Study Description
Brief Summary
CLEARLY will focus on validation of a multifactorial "bio-radiomic" protocol for early diagnosis of lung cancer that combines circulating biomarkers and radiomic analysis. It will (a) assess the role of molecular and cellular biomarkers (exosomes, protein signatures, circulating tumor cells - CTCs, microRNA) and radiomic signature, as complementary to assist early detection of lung cancer by low dose computed tomography-LDCT, using bioinformatics techniques; (b) assess the prognostic role of CTCs including the role of cells epithelial mesenchymal transition (EMT) and (c) standardize a method for genomic analysis of CTCs for early detection of treatment resistance.

Outcome Measures
Primary Outcome Measures
- Validation of the role of a bio-radiomic protocol as complementary tool to assist early detection of lung cancer by LDCT [01 July 2018 - 01 July 2021]
CTC analysis will be performed using fresh plasma samples. Blood collection will be obtained for each lung cancer patient before and after surgery and once for controls. 45- and 16-miRNA signatures will be analyzed on plasma samples of the retrospective cohort (150 lung cancer patients and 120 matched controls). We will perform the exosome antigens analysis in the retrospective cohort. We will validate the 8-protein signature in the retrospective cohort. We will validate the radiomic signature on CT images, and further validation will be performed on CT images of the prospective cohorts collected and 70 screened individuals of the retrospective cohort. We will integrate results of biomarkers and radiomic data and will build a multiparametric risk model to improve early detection of lung cancer. The final predictive model will be then applied to the cohorts analysed and integrated with LDCT results to evaluate the improvement in diagnostic accuracy.
Secondary Outcome Measures
- Correlation of CTC spread to angiogenesis. [01 July 2018 - 01 July 2021]
Number of CTC isolated with ISET technique in the prospective cohort of lung cancer patients and controls will be correlated to angiogenesis aspects of the primary tumor at CT scan, using dynamic perfusion data and quantitative and qualitative assessment of angiogenesis (surface fractal dimension and microvessel density) on hysthological examination.
- Assessment of epithelial mesenchymal transition (EMT) in CTC as a hallmark of poor prognosis. [01 July 2018 - 01 July 2021]
The presence of CTC passed through EMT will be identified using immunoistochimical specific exams. The correlation between the presence of CTCs in EMT and prognostic factors of primary tumor (disease stage, volume doubling time, etc) will show the possible prognostic role of CTC immunoistochemical analysis.
- Standardise a method for genomic analysis from isolated CTCs for the early detection of resistance to treatments [01 July 2018 - 01 July 2021]
A population of patients with advanced stage disease (stage III and IV) will be first analyzed to enrich for CTCs in the collected blood samples. This would help the initial refinement of the experimental protocol to detect CTC and analyse their mutational profile by single-cell NGS analysis. In addition, since most of these patients will undergo systemic treatment, we will setup a longitudinal study where the mutational profile of CTC will be investigated and correlated to chemotherapy response, to early identify theranostic mutations. The same refined protocol will be next validated on the prospective cohort of LDCT screened patients to further prove its validity to early detect cancer driver mutations.
