PROspective Master-protocol for Evaluation of Systemic THErapeutics in Elderly With Thoracic Malignancies

The objective of the study is to prospectively generate real-life data in patients aged ≥70 years treated in first line for a thoracic tumor (Non-Small-Cell Lung Carcinoma) according to best standard of care as defined by the European Society for Medical Oncology (ESMO). This cohort will aim to: * characterize participants in terms of geriatrics, biology and carcinology * describe the treatment modalities by stage, as well as the results in terms of efficacy, safety and impact on quality of life. At the same time, exploratory sub-cohorts will be identified including participants treated uniformly with the same molecule, and/or the same innovative strategy. Participants will be followed in accordance with investigator's usual clinical practice at the corresponding site. They will be asked to: * visit the clinic as per physician's request for checkups and tests for assessing general condition and clinical efficacy and tolerance of current treatment. * perform the necessary regular para-clinical examinations (lab testing, imaging, re-biopsy). * provide blood samples for bio-bank repository * perform assessments specific to older adults * answer three quality of life questionnaires
