A Study to Compare Tissue and Liquid Biopsies in People With Different Types of Cancer

In study, liquid biopsy samples will be obtained from non-small cell lung cancer (NSCLC) including Squamous cell carcinoma, Adenocarcinoma and large cell carcinoma, colorectal carcinoma (CRC) and pancreatic ductal adenocarcinoma (PDAC) patients who undergo treatment according to established standards of care (SoC) at the University Hospital Schleswig-Holstein (UKSH).
This study will observe the overall Variant Allele Frequency (VAF) of circulating tumour Desoxyribonucleic acid (ctDNA) levels over the patient therapeutic treatment course and will correlate these findings with tumour response as well as Kirsten rat sarcoma viral oncogene homolog (KRAS)mutation status.
