Prospective Exploratory Study of FAPi PET/CT With Histopathology Validation in Patients With Various Cancers

This exploratory study investigates how an imaging technique called 68Ga-FAPi-46 PET/CT can determine where and to which degree the FAPI tracer (68Ga-FAPi-46) accumulates in normal and cancer tissues in patients with cancer. Because some cancers take up 68Ga-FAPi-46 it can be seen with PET. FAP stands for Fibroblast Activation Protein. FAP is produced by cells that surround tumors (cancer associated fibroblasts). The function of FAP is not well understood but imaging studies have shown that FAP can be detected with FAPI PET/CT. Imaging FAP with FAPI PET/CT may in the future provide additional information about various cancers.

The NorCUP Trial: Improving Prognosis and Personalized Treatment in Cancer of Unknown Primary (CUP)

The goal of this clinical trial is to improve diagnosis and treatment strategies for patients with Cancer of Unknown Primary (CUP) by using advanced molecular profiling to identify the likely tumor origin and guide therapy. The main questions it aims to answer are: Can comprehensive molecular profiling help determine the origin of CUP tumors? Does identifying the tumor origin improve treatment choices and survival outcomes compared to historical data? Participants will: * Undergo a new biopsy to collect tumor tissue for advanced analyses. * Provide blood samples for circulating tumor DNA (cfDNA/ctDNA) analyses. * Provide a fecal sample for microbiome analysis. * Have their tumor tissue analyzed using: Methylation profiling and comprehensive gene panel testing. * Have the results reviewed in a specialized CUP molecular MDT meeting to determine the likely tumor origin and guide treatment. * Have their tumor tissue samples biobanked for further exploratory whole genome sequencing (WGS) and RNA sequencing.
