This study is a feasibility study to determine if a combined breast PET/CT scanner can image malignant functional activity while determining anatomical structure in the same clinical setting for patients with breast cancer. End-points of this study are whether women will accept the imaging position and timing, and whether functional properties of breast cancer can be imaged with this device. The secondary purpose of this study is to explore protocol parameters with a view to optimizing imaging performance whilst minimizing patient discomfort. Imaging results will be compared to histological samples to determine ground truth.

PET is literally a molecular imaging modality. In monitoring the patient's response to a specific chemotherapeutic regime, baseline and subsequent PET/CT scans can be used to quantitatively determine the therapeutic effect of the regime, using the standard uptake value (SUV), a common metric in PET imaging. The breast PET/CT system will facilitate molecular imaging of breast cancer using a number of radiolabeled molecules, available both commercially (18-FDG) and from the research environment.

Women with diagnosis of intermediate and high-risk early stage endometrial cancer.

Preoperative staging of early stage intermediate and high-risk endometrial cancer with positron emission tomography and computed tomography.

Surgical treatment of early stage intermediate and high-risk endometrial cancer by usual practice: peritoneal cytology, total abdominal hysterectomy, bilateral salpingo-oophorectomy, systematic pelvic and para-aortic lymphadenectomy.

Endometrial cancer (EC) is the most common gynecologic malignancy in the developed countries and is the fifth most common cancer among women worldwide. Typically present well or moderately differentiated, early stage endometrioid histotype with a prognosis usually favorable. Pelvic lymph nodes (LNs) represent the most common site of extra-uterine disease in patients with clinical early stage disease and the role of lymphadenectomy in early stage EC has been one of the major controversies in gynecology oncology. Lymphadenectomy doesn't improve survival or reduce disease recurrence although supported to provide prognostic information and allowing tailoring of adjuvant therapy. Nevertheless, lymphadenectomy is not performed without serious short-term and long-term morbidity. Although surgical staging is the most accurate and standard method to determine LNs involvement, the introduction in clinical practice of a non-invasive modality that allows an accurate staging of EC would be essential. Available evidence report the accuracy of Positron Emission Tomography and Computed Tomography (PET/CT) for the detection of LN metastasis in EC with a sensitivity of 63% and specificity of 94.7%. This prospective comparative analysis between PET/CT, histological findings, and follow up data will be performed to investigate the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy of integrated PET/CT for nodal staging of EC per patient and per LN chain analyses, in women affected by intermediate (grade 1 and 2 endometrioid lesions with deep myometrial invasion \> 50% or grade 3 endometrioid lesion with \< 50% myometrial invasion) or high risk (grade 3 endometrioid lesion with deep myometrial invasion \> 50% or non-endometrioid histotype) early-stage EC. Furthermore, the preoperative classification of EC in intermediate and high-risk class will allow to investigate its prognostic value.
