Updated publication reference for PubMed record(s): 34870237. In this project, two NSCLC cohorts were analyzed by Data Independent Acquisition (DIA-MS). A cohort of early stage NSCLC samples (141) as well as an additional cohort of late stage NSCLC samples (84) with the aim to demonstrate utility of MS for subtyping and treatment prediction in a clinical setting. Further, six identified NSCLC proteome subtypes were investigated in relation to cancer driver pathways and immune phenotypes based on the generated MS-data.
