While FAP expression in normal tissues is usually low or undetectable, it is overexpressed in many cancers, including 90% of carcinomas. FAP is known to be overexpressed in breast, colorectal, pancreatic, lung, bladder, ovarian and other cancers. In these cancers, FAP is usually heavily expressed in the stroma, and has thus become a universal marker of cancer-associated fibroblasts (CAFs). While the presence of FAP in malignant tissues is undisputed, the role of FAP biologically and its impact on disease prognosis has been inconsistent throughout the literature.
