A Prospective Randomized Trial to Study the Impact of Pretreatment FDG-PET for Cervical Cancer Patients With MRI-Detected Positive Pelvic but Negative Para-Aortic Lymphadenopathy

Pretreatment FDG-PET in conjunction with magnetic resonance imaging can improve the detection of extrapelvic metastasis, mainly PALN, and help select patients for extended-field radiotherapy. However, the addition of FDG-PET may not translate into survival benefit, even though PALN relapses are reduced.
