Biological Response of Nasopharyngeal Carcinoma to Radiation Therapy: A Pilot Study Using Serial F-18-FDG PET/CT Scans

We used serial F-18-fluorodeoxyglucose positron emission tomography/computed tomography (F-18-FDG PET/CT) to evaluate tumors' maximum standardized uptake value (SUVmax) before, during, and after radiotherapy to explore the biological behavior of and response to radiation therapy in various subtypes of nasopharyngeal carcinoma (NPC). Sixty-one patients with pathologically diagnosed NPC were prospectively enrolled into the study. WHO type IIB disease had a higher initial SUVmax and more significant biological response at the primary site as compared with type IIA subtype. The two subtypes of WHO type II NPC may significantly differ in their biological behavior and response to radiotherapy.
