RecruitingClinical trialPredicting Responsiveness in Oncology Patients Based on Host Response Evaluation During Anti Cancer Treatments, Using MultiomicsThe goal of this exploratory study is understand the mechanisms of response to immunotherapy in Non-Small Cell Lung Cancer patients. The investigators are going to search for correlation between specific biological features and response to immunotherapy, and to use those associations for developing an algorithm enabling to identify patients that could benefit from the immune check inhibitor based anti cancer treatment. Patients will provide biological samples before and during their treatment, and clinical data will be collected.
