Brief summary
This study aims to better understand the role of immune system cells in lung diseases such as lung cancer, sarcoidosis, and chronic obstructive pulmonary disease (COPD). The investigators are studying how these immune cells can sometimes help the body defend itself, but in other cases may contribute to cancer growth or long-term lung inflammation. Although recent treatments like immunotherapy have improved cancer care, only a small proportion of patients currently benefit from these therapies. One goal of this research is to understand why some patients do not respond or develop resistance to treatment. The knowledge gained from this study may help researchers develop more effective and personalized treatments for people with lung diseases in the future.
Interventions
Participants provide biological samples for immune profiling and translational research. Samples include peripheral blood and, when available from routine clinical care, additional specimens such as tumor tissue or rlymph node, bone marrow. No experimental treatments are given. Collected samples are analyzed to characterize immune cell populations and their functional and molecular features, with the aim of studying immune mechanisms involved in lung cancer, sarcoidosis, and COPD, as well as factors associated with disease progression and treatment response. All medical care and treatment decisions remain independent of study participation.

Study design
Intervention model description
This is a translational, non-interventional study evaluating immune cell populations in patients with lung cancer, sarcoidosis, and COPD. Participants receive only standard clinical care; no experimental treatments are given. Biological samples (primarily blood and when available, tumor, bone morrow samples collected for clinical reasons) and associated clinical data are analyzed to investigate immune mechanisms related to tumor progression, chronic lung inflammation, and response or resistance to therapy. The study is exploratory and comparative across diseases. All treatment decisions are made independently by the treating physicians and are not influenced by study participation.
