Abstract:
The goal of this review is to discuss the current utility of fluorine-18-fluorodeoxyglucose (FDG)-PET for radiation oncologists who treat gynecologic malignancies. FDG-PET/computed tomography (CT) is recommended for baseline assessment in cervical cancer and for staging in vulvar and vaginal cancer. The authors use FDG-PET/CT in definitive radiation treatment planning for cervical, vulvar, and vaginal cancer. PET may be helpful for salvage radiation treatment planning for any recurrent gynecologic malignancy. There are published data to support the use of PET in posttreatment evaluation of cervical and vulvar cancer.
