Abstract: Because positron emission tomography(PET)/computed tomography(CT)plays an important role in diagnosis、clinical staging and optimal treatment of cervical cancer,this leads people to think its value of the prognosis for patients with cervical cancer,especially the value of maximum standardized uptake value(SUVmax)in the prognosis for patients with cervical cancer.Some studies demonstrate that a high pretreatment glucose analog F-¹⁸fluorodeoxyglucose(FDG)uptakes in the primary tumor or lymph node metastasis at diagnosis.As measured by the SUVmax,it is correlated with a lower survival and higher recurrence rate in patients with cervical cancer.The use of PET with FDG to assess post-therapy glucose metabolism in the primary tumor could predict the prognosis for patients with cervical cancer;a complete metabolic response on PET is predictive of a good survival outcome;a partial metabolic response or progressive disease is predictive of a poor survival outcome.
