Nasopharyngeal Cancer
Conditions
Brief summary
The goal of this clinical trial is to learn about the prediction of clinical response to neoadjuvant therapy in nasopharyngeal carcinoma patients via 68Ga-FAPI-46 PET/CT. The main question it aims to answer is: Can 68Ga-FAPI-46 PET/CT be used to evaluate the therapeutic response of neoadjuvant therapy for nasopharyngeal carcinoma？ The researchers will compare the correlation between the parameters obtained after three 68Ga-FAPI-46 PET/CT scans and the treatment response after neoadjuvant and neoadjuvant combined with concurrent chemoradiotherapy. Participants will: Undergo three 68Ga-FAPI-46 PET/CT scans before starting treatment, after neoadjuvant therapy, and after concurrent chemoradiotherapy
