PET imaging of tumor-supporting fibroblast cells in pancreatic cancer using 68Ga‑FAPI‑46

Quantitative In Vivo 68Ga-Fibroblast-Activation-Protein-Inhibitors (FAPI)-46 PET Imaging of Cancer-Associated Fibroblasts (CAFs) in Pancreatic Ductal Adenocarcinoma (PDA)

NIH-funded research Mayo Clinic Rochester · NIH-11190830

This project uses a PET imaging tracer called 68Ga‑FAPI‑46 to reveal fibroblast cells that support pancreatic tumors in people with pancreatic ductal adenocarcinoma.

What this research studies

If you participate, you would get a PET scan using a tracer called 68Ga‑FAPI‑46 that binds to fibroblast activation protein (FAP) on cancer-associated fibroblasts (CAFs). The tracer has low background uptake, clears quickly from blood, and stays in tumor stroma so doctors can map where CAFs live inside and around your tumor. Researchers will compare images across patients and over time to learn how CAF patterns relate to tumor growth, spread, and treatment resistance. This noninvasive imaging could help select patients for future therapies that target the tumor microenvironment.

Who could benefit from this research

Good fit: Ideal candidates are adults with pancreatic ductal adenocarcinoma (newly diagnosed, recurrent, or metastatic) who are able to undergo PET imaging.

Not a fit: People without pancreatic cancer, those whose tumors do not express FAP, or individuals unable to have PET scans (for example, pregnant people) are unlikely to benefit.

Why it matters

Potential benefit: If successful, this imaging approach could help personalize treatment by revealing tumor stromal patterns and identifying patients who might benefit from FAP-targeted therapies.

How similar studies have performed: Early clinical work with 68Ga‑FAPI tracers in several cancers has shown strong tumor imaging signal, but applying this specifically to guide therapy in pancreatic cancer is still relatively new.
