Endometrial cancer (EC) is one of the most common gynaecological malignancies worldwide.The incidence rate of uterine cancer in Egypt was 4.1 per 100,000.
The standard surgery consists of laparotomy, hysterectomy, and bilateral salpingo-oophorectomy. Maximal surgical cytoreduction is recommended for advanced EC. Prognostic impact of complete lymphadenectomy remains controversial, especially in early- stage disease.
With the aim of predicting extrauterine disease pre-operatively and optimizing surgical planning, several techniques have been evaluated, including 18F-fluoro-2-deoxyglucose (18F-FDG) positron emission tomography/computed tomography (PET/CT). PET /CT can be used to effectively and accurately diagnose EC pelvic lymph node metastasis and distant metastasis. It has great value in clinical staging, judging prognosis, diagnosing recurrence.
Radiomics analysis of the uterine primary tumor on pre-operative 18F-FDG PET images may help predict the presence of metastatic nodes, thus reducing false-negative results and increasing the sensitivity of the technique. The maximum standard uptake value (SUVmax), metabolic tumor volume (MTV) and total glycolysis (TLG) of primary lesions are significantly correlated with pathological tissue grading. Previous studies on metabolic parameters of primary lesions examined by 18F-FDG PET/CT for endometrial cancer mainly focused on SUVmax, However, SUVmax can only reflect the functional metabolic degree of the point. It cannot assess the overall metabolic situation of tumor. MTV and TLG can more comprehensively measure the glucose metabolic activity of tumor cells with more clinical value in reflecting the malignancy degree of tumor.

| 18F-FDG PET/CT | Device | The PET/CT procedure will be performed according to the institutional standard with 18F-FDG (0.8-1.2 mCi /kg) injection following 6 h fasting. Blood glucose was controlled to be <150 mg/dl. PET/CT from the vertex to the middle femur will be obtained 60 min after FDG injection. MDCT examination without IV contrast will be done for attenuation correction and anatomic localization followed by PET images from the skull vault to the mid-thigh region. Images of CT and corresponding functional PET images are displayed in axial, coronal and sagittal planes. PET/CT data will include tumor size and extension, LN invasion& distant metastasis SUVmax will be calculated for all positive lesions, Metabolic parameters including SUVmax, SUVmean, TLG & MTV will be calculated for primary tumor. Data of PET will be compared with other diagnostic imaging and postoperative pathologic data. |
