Imaging solid tumors using a new tracer called 68Ga-FAPI

PET Imaging of Tumors in Pancreas, Bile Ducts, Stomach and Ovaries by a Novel Tracer, 68Ga-FAPI-46 = Fibroblast Activation Protein Inhibitor

Phase 1 Interventional Karolinska University Hospital · NCT05172310

This study is testing a new imaging method using a special tracer to see if it can help doctors better detect certain types of cancer in patients who are having surgery.

What this trial studies

This study evaluates the diagnostic accuracy of PET/CT imaging using a novel radiotracer, 68Ga-FAPI, for detecting cancers of the pancreas, stomach, bile ducts, and epithelial ovarian cancer. The approach focuses on the unique properties of cancer-associated fibroblasts (CAFs) within the tumor stroma, which are abundant in these types of cancers. By selectively targeting the Fibroblast Activation Protein (FAP), the study aims to improve the differentiation of malignant lesions from benign conditions, potentially leading to better treatment decisions. Patients scheduled for surgical removal of these tumors will be enrolled to assess the effectiveness of this imaging technique.

Who should consider this trial

Good fit: Ideal candidates include patients scheduled for surgical removal of pancreatic, biliary, gastric lesions, or those with early-stage or recurrent epithelial ovarian cancer.

Not a fit: Patients with known metastatic disease or those with significantly reduced renal function may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more accurate diagnoses of difficult-to-detect cancers, improving treatment outcomes for patients.

How similar studies have performed: While the use of FAPI in imaging is a novel approach, similar studies have shown promising results in targeting cancer-associated fibroblasts for improved imaging.
