The purpose of this study is to develop a lung cancer diagnosis tool using a multi-omics approach based on liquid biopsy.


After being informed about the study and potential risks, all patients giving written informed consent will undergo a screening process to determine eligibility of study entry. Peripheral blood, tissue sample and imaging examinations of eligible patients will be collected for further analysis. Data collected will be used to develop a multi-omics lung cancer diagnosis model.
