Research progress of radiolabeled FAPIs in the tumor targeted diagnosis and therapy / 中华核医学与分子影像杂志

ABSTRACT

Cancer-associated fibroblasts (CAFs) are essential parts of tumor stroma. Fibroblast activation protein (FAP), overexpressed in CAFs, is closely related to tumor growth, invasion, metastasis, immunosuppression and prognosis, which is a vital target for tumor targeted diagnosis and therapy. In recent years, a variety of new radiolabeled quinoline-based FAP inhibitors (FAPIs) have been used for tumor targeted diagnostic and therapeutic research. A number of studies have confirmed that radiolabeled FAPIs plays an important role in tumor diagnosis, staging and treatment, which have a good clinical application prospect. This review summarizes the research status of radiolabeled FAPIs and discusses their potential in the accurate diagnosis and therapy of tumors.
