Brief summary: 1. To assess the value of 18F-FDG PET/CT in the initial staging and detection of recurrent cases of endometrial cancer.
2. To determine correlation between PET/CT derived parameters including SUVmax, TLG and MTV and clinic-pathological patient characteristics.
3. To detect local and distant recurrence after therapy.

Detailed description: 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.

Eligibility criteria: Inclusion Criteria:

* Patients proved to have endometrial cancer by curettage or hysteroscopy.
* Patients accepted surgery treatment, without anti-tumor and hormone therapy before surgery.
* Ability to stay still for the duration of the PET/CT scan (\~15 minutes).
* Ability of the patient (or his/her guardian) to sign informed consent.

Exclusion Criteria:

* Patients who recieved neoadjuvant therapy before PET/CT.
* Patients with tumors other than endometrial cancer.
* Pregnancy.
* Inability to give informed consent.
* Inability to stay still for the duration of the scan.
* Claustrophobia
