Condition: Sarcoma · Small Cell Lung Cancer or Extrapulmonary Neuroendocrine Cancer (EP-NEC) · Mesothelioma · Sponsor: National Cancer Institute (NCI)
Background: Fibroblast-activation protein (FAP) is an enzyme that appears in high numbers in cancer-associated fibroblasts of certain cancer types. \[18F\]FAPI-74 is a new PET (positron emission tomography) tracer, a substance that is injected into a person s body before an imaging scan. Researchers believe that \[18F\]FAPI-74 PET imaging may be able to visualize cancer more effectively than the approved tracers. If so, the new tracer would make it easier to find FAP-positive tumors in the body. Objective: To see if \[18F\]FAPI-74 PET scan is as good or better than other imaging methods for detecting certain cancers. Eligibility: People aged 18 years or older with one of these cancer types: pancreatic ductal adenocarcinoma (PDAC), cholangiocarcinoma, hepatocellular carcinoma (HCC), gastric cancer, bladder cancer, ovarian cancer, pheochromocytoma/paraganglioma (PPGL), small cell lung cancer (SCLC) or extrapulmonary neuroendocrine cancer (EP-NEC), mesothelioma or sarcoma. Participants must be scheduled or intended to receive treatment for cancer. Design: Participants will have 2 baseline scans: an \[18F\]FAPI-74, and the approved tracer \[18F\]-FDG. The \[18F\]FAPI-74 will be infused through a needle inserted into a vein. About 1 hour later, the participant will undergo imaging. Within 1 week, participants will undergo the same scanning procedures with the approved tracer. If the baseline scan with \[18F\]FAPI-74 shows the tumor(s), scans with this tracer will be repe…
