University Hospital Heidelberg Develops Promising PET Imaging Method

Laurel Dubinsky writes in HealthCareBusiness that German researchers have developed a PET imaging method that may raise the bar on diagnosing certain cancers.

The method targets cancer-associated fibroblasts (CAFs), which have been linked to tumor growth and are present in over 90 percent of epithelial carcinomas such as pancreatic, colon and breast cancer. The team created a PET tracer based on a FAP-specific enzyme inhibitor (FAPI).

For a study recently published in the Journal of Nuclear Medicine, they tested the gallium-68-labeled FAPI tracer and a 18F-FDG PET tracer in mouse models as well as a proof-of-concept PET/CT study that involved three patients.

“The competing tracer is FDG, which is hard to beat,” Dr. Uwe Haberkorn of the University Hospital of Heidelberg, told HCB News. “However, we think that due to the high contrast [of] FAPI, [it] may be superior in peritonitis carcinomatosa, liver tumors/metastases, brain metastases, carcinoma of unknown primary, staging of breast cancer and head and neck cancer.”
