Overview

The goal of this observational study is to better understand how the immune system and certain tumor markers are linked to treatment response in patients with advanced non-small cell lung cancer (NSCLC) who receive immunochemotherapy. The investigators aim to answer the following questions: * Can the investigators successfully analyze immune markers and gene activity from small tumor samples (biopsies)? * Are these markers connected to how well patients respond to immunochemotherapy and how their disease progresses? What will participants do? * Provide tumor tissue samples (biopsies) at key points: before treatment, about 6 weeks after starting immunochemotherapy, and if the cancer grows or treatment changes. * Allow their tumor samples to be analyzed in the lab using advanced techniques to measure immune and genetic markers. * Share clinical information (such as treatment response and disease progression) so investigators can study how it relates to these markers. This study does not test a new drug or treatment.

Outcomes

Primary Outcomes

General technical success rate for multiplex immunofluorescence staining per biopsy

defined as a staining, which is: 1. considered evaluable by a trained pathologist according to the HE-, and multiplex-stained overview 2. PanCK positive 3. for which negative control and positive control stained in the same run are negative and positive, respectively. Estimated at 60 %.

Time frame: From enrollment until completion of all planned biopsy time points (baseline, 6 weeks after start of immunochemotherapy, and at each progression or therapy line change), up to approximately 24 months.

General success rate for the 3'RNA-Sequencing Approach per biopsy

defined as 1. successful 3'RNA-isolation and -sequencing, 2. keratin 18 (KRT18) expression is clearly detected above background, e.g. above a 5 Counts per million (CPM) cutoff and 3. is considered evaluable by trained molecular biologist according to the sequencing results. For 3'RNA-Seq, gene-specific expression distributions will be used to calibrate CPM, ranks, or similar metric cutoffs to define positivity/negativity. Estimated at 60 %.
