• Correlation of the change in ctDNA level after six weeks of treatment to ORR, PFS and OS.
• Validated tumor educated platelet algorithm that is associated with increased ORR, PFS and OS.
• Validated tumor educated platelet algorithm that is associated with therapy resistance.
• Correlation of STM-panel based response assessment with radiological response assessment as performed by CT-thorax.
• Correlation of PBMC FACS parameters of lymphoid and myeloid subsets in peripheral blood to tumor response rate, PFS and OS.
• Correlation of rare mutation profile, as assessed by NGS on tumor tissue, to tumor response rate, PFS and OS.
• Correlation of tumor tissue IHC parameters to tumor response rate, PFS and OS.
• Correlation of RNAseq on fresh frozen tumor tissue to tumor response rate, PFS and OS.
• Correlation of CT based parameters to tissue parameters and tumor response rate, PFS and OS.

Background summary
In this study we will explore frozen and paraffin embedded (FFPE) tumor tissue and blood samples from patients that are eligible for immune- and targeted therapy and those who become resistant to immune- and targeted therapy after an initial response. Frozen tumor biopsies will be used for RNA seq and FFPE tissue will be stained with multiple fluorescent targets to identify stimulating and inhibiting immune cells in the tumor. Moreover, blood will be collected to explore the role of circulating blood markers.
Study objective
1. The predictive biomarkers for tumor response to immuno modulating therapy will be a combination of adaptive and innate immune status per patient that will be estimated with a tumor biopsy before, 6 weeks after start treatment (optional) and at progression or recurrence of disease and blood sampling at baseline, in week 2 or 3, 6, 12 and at progression or recurrence of disease. This status can be defined as the different immune cell fractions estimated by CIBERSORT and the LM22 leukocyte signature matrix estimated from RNA sequencing data. Another approach is looking for activating T8+ cells and inhibitory Treg, macrophages and myeloid suppressor cells by immune fluorescence tests in the same biopsy by multispectral imaging. In combination with clinical data the meaning of the different fractions can be assessed in a prospective way.
2. Resistance to targeted therapy that develop early in the course of disease will be limited to gate keeper mutations and a complex delayed resistance due to a multitude of mechanisms.These resistance mechanisms can be discerned by a biopsy from the growing tumor. DNA and RNA seq data will used to illuminate patterns of resistance.
Study design
Blood sampling: 1 whole blood and 2 EDTA at baseline, week 2 or 3, week 6, week 12 and at progression or recurrence of disease.
Tumor biopsie will be taken at baseline, week 6 and at progression or recurrence of disease.
Intervention
Blood drops and optionally a tumor biopsy
