Summary
Positron emission tomography (PET) molecular imaging provides a valuable method for the diagnosis, differential diagnosis and staging of various tumors. Cancer associated fibroblasts (CAFs) are the main components of tumor stroma, which are involved in tumor cell proliferation, invasion, metastasis and tumor angiogenesis, and play an important role in the occurrence and development of tumors. Fibroblast activation protein (FAP) is the most potential specific molecular marker of CAF, which is mainly expressed in stromal fibroblasts of epithelial tumors and is a potential molecular target for tumor diagnosis and treatment. Oral cancer is the most common type of malignant head and neck cancer, seriously endangering human health. Accurate delineation of the primary tumor, detection of regional nodal metastases, distant metastases and second primary tumors are important for determining the therapeutic strategy and prognosis of oral cancer. Currently, the molecular imaging agent most commonly used in clinical practice for oral cancer is 18F-fluoro-deoxy-glucose (18F-FDG). However, 18F-FDG exhibits some shortages. Inflammatory lesions and the surrounding normal tissue such as brain, tonsils and salivary glands show high uptake of 18F-FDG, often affecting the judgment of lesions. In this prospective study, the investigators will use integrated PET/CT with the agent 68Ga-FAPI and conventional imaging agent 18F-FDG to explore the application value of FAP-targeted molecular imaging in the diagnosis and staging for oral cancer.
