Abstract
The distinguishing of uterine leiomyosarcomas (ULMS) and uterine leiomyomas (ULM) before the operation and histopathological evaluation of tissue is one of the current challenges for clinicians and researchers. Recently, a few new and innovative methods have been developed. However, researchers are trying to create different scales analyzing available parameters and to combine them with imaging methods with the aim of ULMs and ULM preoperative differentiation ULMs and ULM. Moreover, it has been observed that the technology, meaning machine learning models and artificial intelligence (AI), is entering the world of medicine, including gynecology. Therefore, we can predict the diagnosis not only through symptoms, laboratory tests or imaging methods, but also, we can base it on AI. What is the best option to differentiate ULM and ULMS preoperatively? In our review, we focus on the possible methods to diagnose uterine lesions effectively, including clinical signs and symptoms, laboratory tests, imaging methods, molecular aspects, available scales, and AI. In addition, considering costs and availability, we list the most promising methods to be implemented and investigated on a larger scale.

Abstract
PURPOSE Uterine sarcomas are rare tumors with poor prognosis due to the high recurrence rates. The current role of 18F-FDG PET/CT in the post-therapy surveillance is not established yet. MATERIALS AND METHODS Forty-one women with uterine sarcoma underwent 73 18F-FDG PET/CT for restaging in suspected recurrence or during follow-up in asymptomatic patients. Histopathology results and/or clinical/imaging follow-up for at least 12 months were considered the reference standard. The diagnostic accuracy and clinical impact of 18F-FDG PET/CT was calculated. RESULTS Thirty-three 18F-FDG PET/CT were positive, while the remaining 40 studies were negative. The overall sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy of 18F-FDG PET/CT were 88%, 98%, 97%, 91% and 93%, respectively. Considering patients with clinical or radiological suspicion of recurrence (n=47) and those during follow-up (n=26), sensitivity, specificity, PPV, NPV and accuracy of 18F-FDG PET/CT were 89%, 100%, 100%, 86% and 94%, and 80%, 95%, 80%, 95% and 92%, respectively. 18F-FDG PET/CT had a positive clinical impact in 9/73 (12%) studies and changed the clinical management in 8/41 (20%) patients. CONCLUSIONS 18F-FDG PET/CT seems to be an accurate method for detection and localization of local and distant recurrence in patients with uterine sarcoma with good sensitivity and specificity and significant impact on clinical decision making.

Abstract
OBJECTIVE Leiomyosarcoma (LMS) is the most common subtype of uterine sarcomas. It is a rare and aggressive tumour. The aim of the present study was to assess the performance of fluorine-18-fluorodeoxyglucose (F-FDG) PET/CT imaging in four clinical settings: initial staging, restaging, monitoring of response to therapy and post-therapy surveillance of uterine LMS. PATIENTS AND METHODS A bicentric retrospective study was carried out on a group of 21 patients with uterine LMS for whom a total of 52 PET/CT scans were available in initial staging (n=11), restaging (n=11), monitoring of response to therapy (n=17) and post-therapy surveillance (n=13). Clinical (minimum 6 months after PET/CT scan) and/or imaging follow-up and pathology were used as the reference standard. RESULTS In the initial staging, the sensitivity, specificity and accuracy of PET imaging were 80, 100 and 91%, respectively. In the restaging and monitoring of response to therapy, all these indices were 100%, whereas they were lower in post-therapy surveillance at 75, 100 and 85%, respectively, because of two false-negative results. False-negative lesions were an infracentimetric lung nodule in the initial staging and a peritoneal nodule that had increased in size between two PET/CT scans in post-therapy surveillance. PET-negative lesions were all identified on the computed tomography (CT) part of the PET/CT; thus, the performances of the exam improved to 100% on taking into account the CT component of the PET/CT. CONCLUSION PET/CT imaging has a high diagnostic yield in the initial staging and restaging of uterine LMS, but seems less sensitive in post-therapy surveillance. Evaluation of the CT part improves the sensitivity of the PET scan. Thus, PET/CT imaging should be considered in patients presenting with LMS.

Abstract
ObjectiveThe main purpose of this article is to explore the current practice for follow-up of gynecological cancer, pointing out the different procedures, to determine the most clinically and cost-effective surveillance strategies after the primary treatment.Materials and MethodsWe analyzed the follow up strategies for ovarian, endometrial, and cervical cancer. All of the topics discussed below arose from the “ESGO State of Art Conference—Follow-up in gynaecological malignancies” in Turin, (September 11–13, 2014;http://torino2014.esgo.org/).ResultsPhysical but these practices should be integrated with biomarkers or imaging strategies. Currently, most recommendations about follow-up are based on retrospective studies and expert opinion, and there is some disagreement on surveillance strategies due to lack of evidence-based knowledge.ConclusionsAll surveillance procedures should be evidence-based with a clearly defined purpose: there is a need for prospective studies to compare the effectiveness of different follow-up regimens measuring overall survival, detection of recurrence, quality of life (QoL), and costs as outcomes.

Abstract
In this report, we describe the case of a 67-year-old woman with metastatic pancreatic uterine leiomyosarcoma. She underwent a total hysterectomy and adnexectomy in December 2009. The resected uterine specimen was characterized as a leiomyosarcoma. The patient was free of disease until November 2010, when three pulmonary tumoral lesions detected by follow-up chest computed tomography were diagnosed as metastatic lesions. Wedge resections and enucleoresection of the pulmonary tumoral nodules were performed, and the patient received adjuvant chemotherapy. Ten months after the lung resection, an abdominal examination showed two tumoral masses in the pancreas and no extrapancreatic recurrence. In April 2014, a pylorus-preserving pancreaticoduodenectomy was performed. To date, the patient is alive, without any evidence of recurrence, and she has received chemotherapy. Surgery can be considered in cases in which the pancreas is a unique metastatic site or even in cases with resectable oligometastases.

Abstract
Leiomyosarcoma of the esophagus is a rare malignant tumor with slow growth and late metastasis. The aim of this study was to reassess the clinical characteristics and treatment modality in one of the largest series of esophageal leiomyosarcomas from a single institution. From February 1973 to December 2011, 12 cases of esophageal leiomyosarcoma were identified. The principal symptoms included progressive dysphagia in 11 cases (91.7%), retrosternal/back pain in four (33.3%), weight loss in four (33.3%), upper gastrointestinal hemorrhage in two (16.7%), and emesis in two (16.7%). The average duration of symptoms was 10.6 months. The location of the primary tumor was in the middle thoracic esophagus in five cases, and lower thoracic esophagus in seven cases. Six cases were classified as the polypoid type, five cases as the infiltrative type, and only one case as the intramural type. All 12 of the patients underwent esophagectomies, and radical resections were achieved in these patients. Based on the Kaplan-Meier Method, the 3-, 5-, and 10-year survival rates were 80.0%, 58.3%, and 31.1%, respectively, with a median survival of 63 months. Five-year survival rates for patients with polypoid or intramural tumors (n = 7) was 83.3%, and for patients with infiltrative tumor (n = 5) it was 25.0%. One of the patients had tumor resected four times and survived for 161 months. In conclusion, patients presenting with esophageal leiomyosarcomas have an excellent prognosis, and radical resection may achieve acceptable results.

Abstract
OBJECTIVE We reviewed the medical literature on the application of fluorine-18-fluorodeoxyglucose positron emission tomography ((18)F-FDG PET) imaging in the management of uterine sarcomas and presented the results in systematic review and meta-analysis format. METHODS Medline, SCOPUS, and ISI Web of Knowledge were searched electronically with "PET AND (Uterine OR Uterus)" as key words. All studies evaluating the accuracy of (18)F-FDG imaging in the staging or restaging of uterine sarcomas were included if enough data could be extracted for calculation of sensitivity and/or specificity. RESULTS Eight studies were included in the systematic review. Only 2 studies reported the accuracy of (18)F-FDG PET imaging in the primary staging of uterine sarcoma with low sensitivity for lymph node staging. For restaging (detection of recurrence), all 8 included studies had quantitative data, and the patient-based pooled sensitivity and specificity were 92.1% (95% confidence interval [95% CI], 82.4-97.4) and 96.2% (95% CI, 87-99.5), respectively. On a lesion-based analysis, sensitivity was 86.3% (95% CI, 76.7-92.9), and specificity was 94.4% (95% CI, 72.7-99.9). Device used (PET vs PET/CT), spectrum of studied patients, and histology of the sarcoma seem to be factors influencing the overall accuracy of (18)F-FDG PET imaging. CONCLUSIONS (8)Fluorine-18-fluorodeoxyglucose PET and PET/CT seem to be accurate methods for detection and localization of recurrence in patients with uterine sarcoma. Further large multicenter studies are needed to validate our results and to correlate both sarcoma type and spectrum of patients to the diagnostic performance of (18)F-FDG PET imaging in recurrence detection. The studies evaluating the accuracy of (18)F-FDG PET imaging for the primary staging of uterine sarcoma are very limited, and no definite conclusion can be made in this regard.

Abstract
Objective The aim of the study was to elucidate the differential metabolic activities in aggressive and indolent subtypes of uterine sarcomas, which may aid in managing these heterogeneous tumours. Methods We retrospectively analysed the PET/computed tomography scans of consecutive patients (N=18) diagnosed with uterine sarcoma at our unit. The patients were divided into indolent (N=4) and aggressive (N=14) tumour groups, and the maximum standardized uptake values (SUVmax) of all lesions (n=134) were measured. The SUVmax of the lesions were compared between the two tumour groups using the Mann–Whitney U-test. We calculated the optimal cutoff value as determined by receiver operating characteristic analysis. A P-value less than 0.05 was considered statistically significant. Results The mean SUVmax of aggressive (n=104) and indolent tumours (n=30) were significantly different (8.0±7.3 vs. 1.9±0.9 respectively; P<0.001). A cutoff of SUVmax greater than 4.0 was able to exclude indolent tumours, with 100% specificity and positive predictive value (sensitivity 72%, negative predictive value 50% and accuracy 78%; area under the curve 97%). By applying this same cutoff value on the most metabolic active lesion in each patient, we were able to correctly classify all but one patient into either the aggressive or indolent tumour group with 100% specificity and positive predictive value (sensitivity 93%, negative predictive value 80% and accuracy 94%). Conclusion Aggressive and indolent uterine sarcoma subtypes have differential metabolic activities that can be used to classify them and this can aid in patient management for preoperative surgical planning and treatment stratification.

Abstract
Follow-up routines after gynaecological cancer vary. The optimal approach is unknown, and no randomised-controlled trials comparing surveillance protocols have been published. In this chapter, we summarise the diagnostic performance of ultrasound, computed tomography, and magnetic resonance imaging in the follow up of women treated for ovarian or uterine cancers. Computed tomography is today the standard imaging method for the follow up of women treated for endometrial, cervical, or ovarian cancer. Six-monthly or annual follow-up examinations have not been shown to positively affect survival. Instead, a combination of transvaginal and transabdominal ultrasound examination with clinical examination might be a more cost-effective strategy for early detection of recurrence. Positron-emission tomography might play a role in women with clinical or serological suspicion of recurrence but without evidence of disease at conventional diagnostic imaging. To create guidelines, more studies, preferably randomised-controlled trials, on follow-up strategies are needed.

Abstract
Recent advances in genetics and pathology have improved our understanding of diagnosis and staging of uterine sarcomas. The major types of uterine sarcomas include leiomyosarcoma, low-grade endometrial stromal sarcoma, undifferentiated endometrial sarcoma, adenosarcoma and carcinosarcoma. The distinctive biological behavior and poor overall survival of uterine sarcoma create challenges in the management of these tumors. We herein present a comprehensive review of taxonomy, epidemiology, pathology, imaging findings and natural history of a wide spectrum of uterine sarcomas.

Abstract
A 60-year-old woman was referred to our hospital with swelling of the right leg. After surgery, leiomyosarcoma of the right leg was diagnosed. Computed tomography showed two hypovascular masses in the pancreatic body and tail that were heterogeneously enhanced compared with the pancreatic parenchyma. On endoscopic ultrasonography, the tumors in the pancreatic body and tail both exhibited regular margins and were visualized as well-circumscribed masses with uneven interiors. Distal pancreatectomy was performed under a presumptive diagnosis of metastatic pancreatic leiomyosarcoma diagnosed based on the findings of EUS-FNA. On laparotomy, peritoneal washing cytology yielded negative results, and no dissemination was observed. Ultimately, metastatic pancreatic leiomyosarcoma was histologically diagnosed.
