Initial experience with positron emission tomography/computed tomography in addition to computed tomography and magnetic resonance imaging in preoperative risk assessment of endometrial cancer patients

ObjectiveImproved preoperative evaluation of lymph node status could potentially replace lymphadenectomy in women with endometrial cancer. PET/CT was routinely implemented the workup cancer at St Olav’s University Hospital 2016. Experience is limited, and there no consensus about use diagnostic The aim study to evaluate accuracy compared standard CT/MRI identifying metastases histologically confirmed as reference. We especially wanted look a supplement sentinel algorithm detection paraaortic nodes.Study designA retrospective included all undergoing surgery for from January 2016 through July 2019 Hospital. Clinical data, results CT, MRI, PET/CT, histopathological were analyzed.ResultsAmong 185 patients included, 27 (15 %) had metastases. 17 (63 pelvic metastases, one (4 isolated 9 (33 both pelvis region. sensitivity, specificity, positive predictive value, negative value 63 %, 98 85 94 93 respectively. 41 73 91 90 respectively (p = 0.07). For 26 sensitivity 58 42 % 0.22). detected 10 100 50 0.06).ConclusionsPET superior cancer, particularly detecting ability PET exclude may strengthen credibility algorithm.
