Abstract
INTRODUCTION Undifferentiated uterine sarcoma is a rare histological subtype of uterine sarcoma. This study aimed to summarize the clinical and pathological presentation of this case. CASE REPORT A 51-years-old patient was admitted to the clinic because of severe pain in the lower abdomen, and scanty bleeding from the genitals. Gynecological examination revealed an enlarged uterus. Conventional and Doppler transvaginal sonography detected a tumorously altered uterus with a maximum diameter of 20 cm a tumefaction with unclear borders and a diameter of 10 cm, with hyperechoic and hypoechoic fields within the tumefaction, presenting pathological vascularization and reduced values of the (Pulsatile index ≤ 1) and (Resistance index ≤ 0.40). Preoperatively, the chest, abdomen, and pelvis were examined. The patient underwent surgery and total abdominal hysterectomy with bilateral salpingo-oophorectomy, and partial omentectomy, with complete removal of the tumor. A pathohistological diagnosis, of undifferentiated uterine sarcoma, was made by excluding other types of uterine sarcomas. At the control examination after completion of chemotherapy, recurrence was ascertained. CONCLUSION undifferentiated uterine sarcoma is an aggressive malignant tumor that in most cases shows rapid progression of the disease after complete resection of the tumor, with a poor prognosis.

Abstract
A woman in her 60s presented with a rare complication of an ovarian cyst which many clinicians may not consider at first presentation. She was admitted with life-threatening staphylococcus aureus sepsis. She presented shocked with a collapse following a 2-day history of diarrhoea, vomiting and pain in the right iliac fossa. She was taken to theatre where a ruptured, widely infarcted left ovarian serous cystadenofibroma was discovered with over 2 litres of purulent fluid exuding from the cyst into the abdomen. She had a left cyst removal, hysterectomy and bilateral salpingo-oophorectomy performed. Histological analysis and molecular gene testing of an incidentally discovered uterine neoplasm revealed an undifferentiated uterine sarcoma. She successfully recovered as an inpatient and was discharged under the care of an oncology team for ongoing management.

Endometrial stromal sarcoma of the sigmoid colon: a case report and literature review. Int Cancer Conf J 2021; 10:294-299. [PMID: 34567941 DOI: 10.1007/s13691-021-00493-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2021] [Accepted: 06/06/2021] [Indexed: 10/20/2022] Open
Abstract
Endometrial stromal sarcoma (ESS) is a rare mesenchymal tumor of the uterus that accounts for 7-25% of uterine sarcomas and < 1% of uterine tumors. Previously reported sites include the ovary, bowel wall, abdomen, peritoneum, pelvis, and vagina; however, ESS in the extrauterine area is rare. We report a rare case of endometrial stromal sarcoma that developed in the sigmoid colon along the gonadal vasculature, which was difficult to distinguish from colon cancer. A large polyp was found in the sigmoid colon of a 74-year-old woman during a routine medical examination and was diagnosed as tubular adenoma. On colonoscopy 7 months later, the tumor had grown and blocked the lumen, causing stenosis. She was referred to our hospital for surgery. Although detailed examination at our hospital did not yield a definitive diagnosis, bowel obstruction was considered likely and we performed laparoscopic low anterior resection under a preoperative diagnosis of sigmoid colon cancer. The tumor protruded into the sigmoid colon from the stump of the ovarian arteries and veins outside the intestinal tract. As the left ovarian artery and vein were involved in the tumor, we extracted them as a lump. The tumor was diagnosed as low-grade ESS (LG-ESS). She had a history of hysterectomy and left salpingo-oophorectomy for uterine myoma 25 years ago, and radiation therapy was performed after surgery for an unknown reason. The postoperative course was uneventful, and follow-up was continued at the request of the patient. We report a rare case of ESS infiltrating the sigmoid colon, which was probably a lesion derived from endometriosis of the ovarian arteriovenous stump remaining after surgery 25 years ago.

World J Surg Oncol 2021; 19:223. [PMID: 34321013 PMCID: PMC8320213 DOI: 10.1186/s12957-021-02333-z] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2021] [Accepted: 07/13/2021] [Indexed: 12/21/2022] Open
Abstract
BACKGROUND While large-scale genomic analyses symbolize a precious attempt to decipher the molecular foundation of uterine leiomyosarcoma (ULMS), bioinformatics results associated with the occurrence of ULMS based totally on WGCNA and CIBERSORT have not yet been reported. This study aimed to screen the hub genes and the immune cell infiltration pattern in ULMS by bioinformatics methods. METHODS Firstly, the GSE67463 dataset, including 25 ULMS tissues and 29 normal myometrium (NL) tissues, was downloaded from the public database. The differentially expressed genes (DEGs) were screened by the 'limma' package and hub modules were identified by weighted gene co-expression network analysis (WGCNA). Subsequently, gene function annotations were performed to investigate the biological role of the genes from the intersection of two groups (hub module and DEGs). The above genes were calculated in the protein-protein interaction (PPI) network to select the hub genes further. The hub genes were validated using external data (GSE764 and GSE68295). In addition, the differential immune cell infiltration between UL and ULMS tissues was investigated using the CIBERSORT algorithm. Finally, we used western blot to preliminarily detect the hub genes in cell lines. RESULTS WGCNA analysis revealed a green-yellow module possessed the highest correlation with ULMS, including 1063 genes. A total of 172 DEGs were selected by thresholds set in the 'limma' package. The above two groups of genes were intersected to obtain 72 genes for functional annotation analysis. Interestingly, it indicated that 72 genes were mainly involved in immune processes and the Neddylation pathway. We found a higher infiltration of five types of cells (memory B cells, M0-type macrophages, mast cells activated, M1-type macrophages, and T cells follicular helper) in ULMS tissues than NL tissues, while the infiltration of two types of cells (NK cells activated and mast cells resting) was lower than in NL tissues. In addition, a total of five genes (KDR, CCL21, SELP, DPT, and DCN) were identified as the hub genes. Internal and external validation demonstrated that the five genes were over-expressed in NL tissues compared with USML tissues. Finally, the correlation analysis results indicate that NK cells activated and mast cells activated positively correlated with the hub genes. However, M1-type macrophages had a negative correlation with the hub genes. Moreover, only the DCN may be associated with the Neddylation pathway. CONCLUSION A series of evidence confirm that the five hub genes and the infiltration of seven types of immune cells are related to USML occurrence. These hub genes may affect the occurrence of USML through immune-related and Neddylation pathways, providing molecular evidence for the treatment of USML in the future.

Essential Oils, Pituranthos chloranthus and Teucrium ramosissimum, Chemosensitize Resistant Human Uterine Sarcoma MES-SA/Dx5 Cells to Doxorubicin by Inducing Apoptosis and Targeting P-Glycoprotein. Nutrients 2021; 13:nu13051719. [PMID: 34069490 PMCID: PMC8160977 DOI: 10.3390/nu13051719] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2021] [Revised: 05/13/2021] [Accepted: 05/15/2021] [Indexed: 01/02/2023] Open
Abstract
The multidrug resistance phenotype is a global phenomenon and causes chemotherapy failure in various cancers, such as in uterine sarcomas that have a high mortality rate. To overcome this phenotype, there is growing research interest in developing new treatment strategies. In this study, we highlight the potential of two essential oils from the Apiaceae family, Pituranthos chloranthus (PC) and Teucrium ramosissimum Desf. (TR), to act as chemopreventive and chemosensitizing agents against two uterine sarcoma cell lines, MES-SA and P-gp-overexpressing MES-SA/Dx5 cells. We found that PC and TR were able to inhibit the cell viability of sensitive MES-SA and resistant MES-SA/Dx5 cells by a slight modulation of the cell cycle and its regulators, but also through a significant induction of apoptosis. The molecular mechanism involved both caspase pathways associated with an overproduction of reactive oxygen species (ROS) and mitochondrial membrane depolarization. Very interestingly, the combination of doxorubicin with PC or TR induced a synergism to increase cell death in resistant MES-SA/Dx5 cells and, subsequently, had the benefit of decreasing the resistance index to doxorubicin. These synergistic effects were reinforced by a decrease in P-gp expression and its P-gp adenosine triphosphatase (ATPase) activity, which subsequently led to intracellular doxorubicin accumulation in resistant sarcoma cells.

Abstract
Endometrial stromal cell sarcomas (ESS) are a unique subtype of uterine malignancy. Recurrent low grade endometrial stromal sarcomas (LESS) is identified in half of the patients. Here, we discuss a case of a 76-year-old Asian female with a past medical history of adenomyosis and hypertension who presented to the outpatient clinic with a chief complaint of painless hematuria for one day. Computed tomography scan of abdomen and pelvis with contrast showed a new right-sided mixed cystic and solid pelvic mass measuring up to 6 cm, obstructing and invading the distal right ureter, which was concerning for malignancy. Positron emission tomography (PET scan) demonstrated a right pelvic mass with increased radiotracer activity consistent with malignancy. She underwent laparotomy with excision of the right-sided pelvic mass with an abdominal washout and at the same time, also underwent cystoscopy with right ureteral stent placement. Tissue pathology was consistent with spindle cell neoplasm with staining and histologic features consistent with a recurrent stromal cell sarcoma. Uterine sarcomas tend to have an aggressive nature but there are key features about ESS that distinguish it from other uterine sarcomas. ESS has a more indolent clinical course and can reoccur years after initial diagnosis. They usually relapse locally, although relapses in extra-uterine sites have also been reported. Treatment of ESS depends on the grade and stage at the time of diagnosis. The main line of treatment for ESS consists of a total abdominal hysterectomy (TAH) and salpingo-oophorectomy (BSO). The significance of this case demonstrates that, although remission can be obtained after the initial diagnosis, recurrence can happen. Even when patients seem to be disease-free, clinicians should follow them closely; early diagnosis is important as treatment for this type of entity has a high survival rate.

Abstract
BACKGROUND Uterine sarcomas (US) constitute a rare heterogeneous group of gynecological malignancies with aggressive characteristics and poor prognosis. Identifying the histopathological factors that determine the prognosis of the tumor and efficacy of various treatment modalities provides a reliable source for efficient treatment of affected patients. This study presents our 11-year experience with US in the south of Iran. METHODS Medical records of 42 patients (2001-2012) with endometrial stromal sarcoma (ESS), leiomyosarcoma (LMS), and malignant mixed Müllerian tumor (MMMT) were investigated. Hazard ratio (HR) and 2- and 5-year survival of patients were analyzed based on the patients' age, histopathological characteristics (tumor type, stage, necrosis, and mitotic index), and treatment modalities. RESULTS Twenty-four patients survived with median follow-up of 42.5 months; 18 died within 17 months, and 52.4% had recurrence, of whom 12 died. Two- and five-year survival rate was 78.6% and 61.9%, respectively, longest for ESS and shortest for MMMT. Higher age, tumor stage, necrosis, and mitotic index increased the HR of mortality. Radiotherapy resulted in a better survival, compared with chemotherapy alone or combined with radiotherapy. CONCLUSION Although ESS had the best prognosis, MMMT was the most aggressive tumor with the shortest survival time. Histological type of the tumor, staging, tumor necrosis, and mitotic index had prognostic roles. Adjuvant radiotherapy resulted in a better survival, compared with surgery alone in early stage.

Abstract
OBJECTIVE High grade endometrial stromal sarcoma and undifferentiated uterine sarcomas are associated with a very poor prognosis. Although large surgical resection is the standard of care, the optimal adjuvant strategy remains unclear. METHODS A retrospective analysis of patients with localized high grade endometrial stromal sarcoma and undifferentiated uterine sarcomas (stages I-III) treated in 10 French Sarcoma Group centers was conducted. RESULTS 39 patients with localized high grade endometrial stromal sarcoma and undifferentiated uterine sarcomas treated from 2008 to 2016 were included. 24/39 patients (61.5%) were stage I at diagnosis. 38/39 patients underwent surgical resection, with total hysterectomy and bilateral oophorectomy completed in 26/38 (68%). Surgeries were mostly resection complete (R0, 23/38, 60%) and microscopically incomplete resection (R1, 6/38, 16%). 22 patients (58%) underwent postoperative radiotherapy (including brachytherapy in 11 cases), and 11 (29%) underwent adjuvant chemotherapy. After a median follow-up of 33 months (range 2.6-112), 17/39 patients were alive and 21/39 (54%) had relapsed (9 local relapses and 16 metastases). The 3 year and 5 year overall survival rates were 49.8% and 31.1%, respectively, and 3 year and 5 year disease free survival rates were 42.7% and 16.0%, respectively. Median overall survival and disease free survival were 32.7 (95% CI 16.3-49.1) and 23 (4.4-41.6) months, respectively. Medians were, respectively, 46.7 months and 39.0 months among those who underwent adjuvant radiotherapy and 41.0 months and 10.3 months for those who underwent adjuvant chemotherapy. In multivariate analysis, adjuvant radiotherapy was an independent prognostic factor for overall survival (P=0.012) and disease free survival (P=0.036). Chemotherapy, International Federation of Gynecology and Obstetrics I-II stages, and Eastern Cooperative Oncology Group-performance status 0 correlated with improved overall survival (P=0.034, P=0.002, P=0.006), and absence of vascular invasion (P=0.014) was associated with better disease free survival. CONCLUSIONS The standard treatment of primary localized high grade endometrial stromal sarcoma and undifferentiated uterine sarcomas is total hysterectomy and bilateral oophorectomy. The current study shows that adjuvant radiotherapy and adjuvant chemotherapy appear to improve overall survival. A prospective large study is warranted to validate this therapeutic management.

Could miRNA Signatures be Useful for Predicting Uterine Sarcoma and Carcinosarcoma Prognosis and Treatment? Cancers (Basel) 2018; 10:cancers10090315.

Abstract
Changes in microRNA (miRNA) expression may lead to cancer development and/or contribute to its progression; however, their role in uterine sarcomas is poorly understood. Uterine sarcomas (US) belong to a rare class of heterogeneous tumors, representing about 1% of all gynecologic neoplasms. This study aimed to assess the expression profile of 84 cancer-related miRNAs and to evaluate their correlation with clinical pathological features. Eighty-two formalin-fixed paraffin-embedded (FFPE) samples were selected. In leiomyosarcoma (LMS), there was an association of lower cancer-specific survival (CSS) with the downregulation of miR-125a-5p and miR-10a-5p, and the upregulation of miR-196a-5p and miR-34c-5p. In carcinosarcoma (CS), lower CSS was associated with the upregulation of miR-184, and the downregulation of let-7b-5p and miR-124. In endometrial stromal sarcomas (ESS), the upregulation of miR-373-3p, miR-372-3p, and let-7b-5p, and the down-expression of let-7f-5p, miR-23-3p, and let-7b-5p were associated with lower CSS. Only miR-138-5p upregulation was associated with higher survival rates. miR-335-5p, miR-301a-3p, and miR-210-3p were more highly expressed in patients with tumor metastasis and relapse. miR-138-5p, miR-146b-5p, and miR-218-5p expression were associated with higher disease-free survival (DFS) in treated patients. These miRNAs represent potential prediction markers for prognosis and treatment response in these tumors.

Abstract
Objective: To evaluate the clinicopathologic characteristics, treatment methods, survival, and prognosis of uterine leiomyosarcoma (ULMS). Materials and Methods: All patients with ULMS who were treated between January 1998 and October 2012 were retrospectively reviewed. A total of 37 women who met the inclusion criteria were included in the present study. Univariate and multivariate analyses were used to identify the risk factors for overall survival (OS) and progression-free survival (PFS). Results: The majority of patients had stage 1 disease (IA, n=9 (24.3%); IB, n=23 (62.1%)). All patients underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy. Additionally, only pelvic, and pelvic plus para-aortic lymphadenectomy was performed in 5 (13.5%) and 8 (21.6%) women, respectively. Adjuvant treatment was administered to 27 (72.9%) patients. Patients who did not receive adjuvant therapy had stage 1 disease. Recurrences occurred in 5 (13.5%) patients. The median follow-up period was 71 months (range 1-158 months). The 5-year PFS and OS rates were 68% and 74%, for all patients. The 5-year OS rates for women with stage 1 and ≥ stage 2 disease were 82% and 27%, respectively. Multivariate analysis confirmed stage 1 disease as the only independent predictor of both PFS (Odds ratio (OR) 10.955, 95% confidence interval (CI) 1.686-71.181, (p=0.012)) and OS (OR 57.429, 95% CI 3.287-1003.269, (p=0.006)). Conclusions: Extensive surgery is not associated with prognosis and stage 1 disease is the only independent good prognostic factor for survival in patients with ULMS.

Abstract
Leiomyosarcoma (LMS) is a rare tumour and comprises 2–3% of all malignant uterus neoplasms [1]. Leiomyosarcoma is characterised by aggressive behaviour, high recurrence rates, and poor overall survival, despite multimodal treatment [3]. Surgery is the main treatment and consists of total abdominal hysterectomy. A randomised trial consisting of 224 patients diagnosed with uterine sarcomas stage I and II showed that adjuvant radiotherapy improves locoregional control. The role of adjuvant chemotherapy is still unclear [1]. Unfortunately, roughly 50% of patients with organ-confined disease will usually develop distant metastasis to lung, peritoneum, liver, pelvic, and para-aortic lymph nodes. Brain metastases are extremely rare [5].

Abstract
This is the first study carried out to describe the role of fetal microchimerism (FM) in the pathogenesis of uterine cancer. The prevalence and concentration of male fetal microchimeric cells (FMCs) were examined in endometrial tissues in relation to subtypes of uterine cancer, and the histological grade and stage of the tumor. FM occurrence was analyzed in relation to risk factors, including hypertension, obesity, type 2 diabetes, dyslipidemia, age at cancer diagnosis, and patient pregnancy history. The prevalence and concentration of FMCs were examined in endometrial tissues using real-time polymerase chain reaction, SRY and β-globin sequences as markers for male fetal FMCs and total DNA. The studied group involved 47 type 1 endometrial cancers, 28 type 2 endometrial cancers, and 41 benign uterine diseases. While the prevalence of FM was decreased only in type 1 endometrial cancer, compared with benign uterine disorders (38.3% vs.70.7%; odds ratio [OR]=0.257, 95% confidence interval [CI]: 0.105 to 0.628, p=0.003), FMC concentrations did not differ within examined groups. The lower FM prevalence was detected in low-grade (grade 1 and grade 2) endometrioid cancer (38.3% vs. 70.7%, OR=0.256, 95% CI: 0.105 to 0.627, p=0.003) and in FIGO 1 tumors (40.7% vs. 70.7%, OR=0.285, 95% CI: 0.120 to 0.675, p=0.004). No correlation between FM prevalence or FMC concentrations and risk factors was demonstrated. A lower prevalence of male FM seemed to be associated with better prognoses in uterine cancer based on tumor subtype, histological grade, and stage of the tumor.

Abstract
Background: Undifferentiated uterine sarcoma (UUS) is a rare tumor with an aggressive growth pattern. They occur in women from 40 to 60 years and are generally characterized by poor prognosis, a high rate of local recurrence, and distant metastases. UUS accounts for 0.2% of all gynecological malignancies. Possible treatments include surgery, radiotherapy, and chemotherapy. Case Description: A 65-year-old female with postmenopausal bleeding was found to have a uterine mass for which she underwent a total abdominal hysterectomy, bilateral salpingo-oophorectomy, and omentectomy. The pathologic evaluation was consistent with undifferentiated endometrial sarcoma. She began experiencing headaches with associated visual disturbances. Magnetic resonance imaging (MRI) of the brain showed a homogenous enhancing occipital dural-based mass measuring 1.6 × 1.8 × 1.7 cm. Due to the rarity of metastatic uterine sarcoma to the brain, this was believed to represent a meningioma and subsequently observed. Interval MRI scan revealed a significant increase in size of the right occipital mass to 2.3 cm with increased edema and mass effect. She underwent right occipital image guided craniotomy for resection of the mass. Histopathology confirmed UUS metastases. Conclusion: Randomized trials analyzing these treatment options are limited due to the rarity of this disease; therefore, a standard therapy is not established. Based on a review of the literature, this is only the fourth case reported of UUS metastatic to the brain.

Abstract
PURPOSE There is a controversy in the literature regarding the role and the prognostic significance of serum markers in uterine carcinosarcomas (CSs). We attempted to determine the utility of serum CA 125, CA 15-3, CA 19-9, and CEA as prognostic factors and disease follow-up in patients with CS of the uterus. METHODS Thirty-seven patients with CS of the uterus were included in this study. Information regarding demographic, clinical, pathologic, tumor marker data (CA 125, CA 19-9, CA 15-3, and CEA both pre- and postoperatively) treatment and outcome information was obtained, followed by Statistical analysis. RESULTS The mean follow-up period was 3.5 years. None of the study serum markers showed significant association with the outcome. Greater hazard was found for cases that staged from IIIA to IV compared to those staged from IA to IIB (HR = 4.75, 95 % CI: 1.99-11.3). Also, greater hazard was found for adenosquamous histological type compared to the other histological types. When multiple Cox regression analysis with stepwise approach was implied, it indicated stage as the only significant factor for the outcome. Elevated CA19-9 was more frequent in cases with heterologous sarcoma (p = 0.036). CONCLUSION In this retrospective study, none of the preoperative serum tumor markers, neither epithelial component, histological type, nor grade showed a significant association with prognosis. This null finding may have significant implications in the common clinical practice; given that there is a controversy in the literature regarding the role and the significance of the prognostic significance of serum CEA, CA 125, CA 19-9, and CA 15-3.

Abstract
PURPOSE The significance of mTOR activation in uterine leiomyosarcoma (ULMS) and its potential as a therapeutic target were investigated. Furthermore, given that effective therapies likely require combination mTOR blockade with inhibition of other targets, coupled with recent observations suggesting that Aurora-A kinase (Aurk-A) deregulations commonly occur in ULMS, the preclinical impact of dually targeting both pathways was evaluated. EXPERIMENTAL DESIGN Immunohistochemical staining was used to evaluate expression of activated mTOR components in a large (>200 samples) ULMS tissue microarray. Effects of mTOR blockade (using rapamycin) and Aurk-A inhibition (using MLN8237) alone and in combination on human ULMS cell growth, cell-cycle progression, and apoptosis were assessed in cellular assays. Drug interactions were determined via combination index analyses. The antitumor effects of inhibitors alone or in combination were evaluated in vivo. RESULTS Enhanced mTOR activation was seen in human ULMS samples. Increased pS6RP and p4EBP1 expression correlated with disease progression; p4EBP1 was found to be an independent prognosticator of patient outcome. Rapamycin inhibited growth and cell-cycle progression of ULMS cell strains/lines in culture. However, only a cytostatic effect on tumor growth was found in vivo. Combining rapamycin with MLN8237 profoundly (and synergistically) abrogated ULMS cells' growth in culture; interestingly, these effects were seen only when MLN8237 was preadministered. This novel therapeutic combination and scheduling regimen resulted in marked tumor growth inhibition in vivo. CONCLUSIONS mTOR and Aurk-A pathways are commonly deregulated in ULMS. Preclinical data support further exploration of dual mTOR and Aurk-A therapeutic blockade for human ULMS.

Abstract
O6-methylguanine-DNA methyltransferase (MGMT) gene promoter hypermethylation is observed in a number of solid tumors and is correlated with the silencing of MGMT expression. In glioblastoma patients treated with the alkylating agent temozolomide, MGMT gene methylation status was shown to have predictive value in terms of prolonged overall survival. Recently, temozolomide has demonstrated promising activity in the treatment of soft tissue sarcomas, including those of the uterus. The tissue specimens involving tumor samples and normal uterine fragments were obtained from nine patients with smooth muscle uterine sarcoma, 11 with stromal uterine sarcoma and 17 with mixed uterine tumors. MGMT gene promoter methylation was analyzed by combined bisulfite restriction analysis (COBRA) while its expression levels were assessed using the real-time reverse transcription polymerase chain reaction (qRT-PCR). MGMT promoter methylation was observed in 27% of all tumor samples analyzed. When stratified by the disease type, 55.5% (5/9) of smooth muscle sarcomas, 23.5% (4/17) of mixed uterine tumor tissues and 9% (1/11) of stromal sarcomas showed MGMT methylation. The MGMT promoter methylation was associated with lower levels of gene expression in tumors when compared with those with an unmethylated promoter (P=0.0232) or normal tissues (P=0.0141). To conclude, MGMT promoter methylation and downregulation of gene expression is observed in a fraction of carcinosarcomas and non-epithelial malignant tumors of corpus uteri. The assessment of MGMT promoter methylation status may potentially identify patients who would benefit from temozolomide treatment.

Abstract
RATIONALE There is little knowledge regarding mullerian adenosarcoma and its metastasizing pattern. AIM Our objective was to evaluate the impact on the prognostic of the patient brought by tumor metastasizing to the retroperitoneum, to analyze the particularities of the treatment in such cases and to bring a significant change in the early therapeutic attitude to mullerian adenosarcomas. METHODS AND RESULTS We present a first case report of a hypervascularized retroperitoneal metastasis from an initial low-grade uterine adenosarcoma. The presence of such a metastasis brought the worst prognostic factor to the patient. CONCLUSIONS We consider that in front of a macroscopic polypoid mass there should be an active change in the diagnosis and in the therapeutic attitude. The frequent confusion between similar histopathological entities with different aggressiveness states and specific treatment responses, the poor outcome at advanced tumor stages, frequently in young patients, should trigger a universal remodeling in approaching these tumors.

Abstract
OBJECTIVES It was the aim of this study to evaluate clinicopathological characteristics and prognostic factors of uterine leiomyosarcomas (LMS). METHODS Twenty-eight patients with uterine LMS were evaluated in this retrospective study. Their features and survival were analyzed by Kaplan-Meier and log-rank tests. RESULTS The median age of the patients was 52 years (range 25-74). Nine patients had a disease with a mitotic count <10/10 high-power fields. Twenty-one patients presented with stage I disease, 1 with stage II and 6 with stage IV. Twelve patients underwent total hysterectomy and bilateral salpingo-oophorectomy, 2 simple hysterectomy, 5 myomectomy and 9 more comprehensive surgical treatments. Adjuvant chemotherapy was administered to 16 patients, whereas chemoradiation was given only to 2 patients. Fifty percent presented with recurrence of the disease. The median overall survival was 46 months. Age, mitotic count, type of surgery, adjuvant therapy, recurrence and clinical response to chemotherapy were not found to affect survival, while the menopausal status and FIGO (International Federation of Gynecology and Obstetrics) stage were found to be prognostic factors. CONCLUSION In our series, the menopausal state and FIGO stage were found to be prognostic factors related to survival.

Abstract
BACKGROUND Uterine leiomyosarcomas are rare and aggressive malignancies of the uterine corpus with high recurrence rates and poor prognoses. The current recommendation for detection of recurrent uterine leiomyosarcoma involves periodic physical examination and conventional imaging such as CT or MRI. The role of fluorine-18-fluorodeoxyglucose positron emission tomography with integrated computed tomography (FDG-PET/CT) in the detection of recurrent uterine leiomyosarcomas is not yet established. PURPOSE To evaluate the use of FDG-PET/CT as a single integrated modality for the evaluation of suspected recurrent uterine leiomyosarcomas. MATERIAL AND METHODS A retrospective study was performed on patients who underwent FDG-PET/CT scans for suspected recurrent uterine leiomyosarcoma. Only patients with follow-up data were included in the study. FDG-PET/CT was evaluated as a single integrated imaging modality. A positive lesion on FDG-PET/CT was defined as a focal abnormality detected on either the PET or CT components, or both. RESULTS Sixteen consecutive patients over 5 years underwent FDG-PET/CT for suspected recurrent uterine leiomyosarcoma. Five patients were excluded due to incomplete follow-up data. The remaining 11 patients were aged 36-58 years (mean age 48). FDG-PET/CT had a sensitivity of 100% (95% CI 63-100) and specificity of 100% (95% CI 20-100) for the detection of recurrent uterine leiomyosarcomas. Sites of metastases include lungs, peritoneum, liver, pancreas and breast, of which lungs and peritoneum were the most common. Two (18%) patients had discordant findings: FDG-PET negative metastatic nodules in the breast and lung detected on the CT component. The maximum standardized uptake value (SUVmax) of metastatic lesions ranged from 2.0 to 16.0 (mean 7.6). CONCLUSION FDG-PET/CT as a single integrated modality may be a useful for the evaluation of suspected recurrent uterine leiomyosarcomas. FDG-PET negative discordant nodules detected on the CT component may represent metastases and should be followed up closely.

Abstract
Uterine sarcomas are a group of rare tumours that provide considerable challenges in their treatment. Radiological diagnosis prior to hysterectomy is difficult, with the diagnosis frequently made post-operatively. Current staging systems have been unsatisfactory, although a new FIGO staging system specifically for uterine sarcomas has now been introduced, and may allow better grouping of patients according to expected prognosis. While the mainstay of treatment of early disease is a total abdominal hysterectomy, it is less clear whether routine oophorectomy or lymphadenectomy is necessary. Adjuvant pelvic radiotherapy may improve local tumour control in high risk patients, but is not associated with an overall survival benefit. Similarly there is no good evidence for the routine use of adjuvant chemotherapy. For advanced leiomyosarcoma, newer chemotherapy agents including gemcitabine and docetaxel, and trabectedin, offer some promise, while hormonal therapies appear to be more useful in endometrial stromal sarcoma. Novel targeted agents are now being introduced for sarcomas, and uterine sarcomas, and show some indications of activity. Non-pharmacological treatments, including surgical metastatectomy, radiofrequency ablation, and CyberKnife(®) radiotherapy, are important additions to systemic therapy for advanced metastatic disease.
