PET / PET-CT and Cancer Cervix Lymph Nodal Staging

ROC curve for PET to detect pelvic nodal metastasis in newly diagnosed cervical cancer, with 95% confidence intervals (Area under curve = 0.970).

PET

MR

CT

Sensitivity: 79% (95% CI: 65-90%)

Specificity: 99% (95% CI: 96-99%)

No enough evidence exists for detection of nodal disease in early Cx cancer and cannot replace lymph nodal dissection
