Exploring the Application Value of PET Molecular Imaging Targeting FAP in Oral Squamous Cell Carcinoma

This Chinese study uses a specialized PET scan targeting a protein called FAP (fibroblast activation protein), which is found in the connective tissue surrounding oral cancer tumors, to see if this imaging approach can better detect and map oral squamous cell carcinoma compared to standard scans. **You may be eligible if...** - You are 18–70 years old - You are highly suspected of having oral cancer, or you have had treatment for oral cancer and there is concern about recurrence - You are scheduled for surgery (or neoadjuvant therapy followed by surgery) - You are able to complete the required PET/CT imaging **You may NOT be eligible if...** - You are pregnant or breastfeeding or planning pregnancy during the trial - You have a known allergy to the imaging agents used (FAPI or FDG) - Your heart, lungs, liver, or kidneys are too weak to tolerate surgery - Your fasting blood sugar is above 11.0 mmol/L before the FDG injection - You have claustrophobia or cannot lie still for 15–30 minutes Talk to your doctor to see if this trial is right for you.
