Gynecol Oncol 2017; 147:167-180. [PMID: 28760367 DOI: 10.1016/j.ygyno.2017.07.120] [Citation(s) in RCA: 76] [Impact Index Per Article: 10.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2017] [Revised: 07/08/2017] [Accepted: 07/08/2017] [Indexed: 01/21/2023]
Abstract
BACKGROUND Endometrial cancer is one of the most common gynecological cancers, which is frequently preceded by atypical endometrial hyperplasia, a premalignant lesion. Metformin, an antidiabetic drug, has emerged as a new adjunctive strategy for different cancer types, including endometrial cancer. This systematic review and meta-analysis aimed to evaluate the effects of metformin in atypical endometrial hyperplasia and endometrial cancer patients. METHODS The search was conducted on January 2017 and the articles were collected in Cochrane, LILACS, PubMed, Scopus and Web of Science. A grey literature search was undertaken using Google SCHOLAR, ProQuest and Open Grey. Nineteen studies were included, which contained information about the following outcomes: reversal of atypical endometrial hyperplasia, cellular proliferation biomarkers expression and overall survival in metformin-users compared to non-users. RESULTS Metformin was associated with reversion of atypical endometrial hyperplasia to a normal endometrial, and with decreased cell proliferation biomarkers staining, from 51.94% (CI=36.23% to 67.46%) to 34.47% (CI=18.55% to 52.43%). However, there is a high heterogeneity among studies. Metformin-users endometrial cancer patients had a higher overall survival compared to non-metformin users and non-diabetic patients (HR=0.82; CI: 0.70-0.95; p=0.09, I2=40%). CONCLUSION Regardless the high heterogeneity of the analyzed studies, the present review suggests that adjunct metformin treatment may assist in the reversal of atypical endometrial hyperplasia to normal endometrial histology, in the reduction of cell proliferation biomarkers implicated in tumor progression, and in the improvement of overall survival in endometrial cancer. Further work on prospective controlled trials designed to address the effects of adjunct metformin on clinical outcomes is necessary for definite conclusions.

Expression of L1CAM in curettage or high L1CAM level in preoperative blood samples predicts lymph node metastases and poor outcome in endometrial cancer patients. Br J Cancer 2017; 117:840-847. [PMID: 28751757 PMCID: PMC5589986 DOI: 10.1038/bjc.2017.235] [Citation(s) in RCA: 25] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2017] [Revised: 06/23/2017] [Accepted: 06/28/2017] [Indexed: 12/19/2022] Open
Abstract
BACKGROUND Several studies have identified L1 cell adhesion molecule (L1CAM) as a strong prognostic marker in endometrial cancer. To further underline the clinical usefulness of this biomarker, we investigated L1CAM as a predictive marker for lymph node metastases and its prognostic impact in curettage specimens and preoperative plasma samples. In addition, we aimed to validate the prognostic value of L1CAM in hysterectomy specimen. METHODS Immunohistochemical staining of L1CAM was performed for 795 hysterectomy and 1134 curettage specimen from endometrial cancer patients. The L1CAM level in preoperative blood samples from 372 patients was determined using ELISA. RESULTS Expression of L1CAM in curettage specimen was significantly correlated to L1CAM level in corresponding hysterectomy specimen (P<0.001). Both in curettage and preoperative plasma samples L1CAM upregulation was significantly associated with features of aggressive disease and poor outcome (P<0.001). The L1CAM was an independent predictor of lymph node metastases, after correction for curettage histology, both in curettage specimen (P=0.002) and plasma samples (P=0.048). In the hysterectomy samples L1CAM was significantly associated with poor outcome (P<0.001). CONCLUSIONS We demonstrate that preoperative evaluation of L1CAM levels, both in curettage or plasma samples, predicts lymph node metastases and adds valuable information on patient prognosis.

Abstract
BACKGROUND Increasing incidence and new indications for existing drugs make it important to identify new adjuvant therapies for endometrial cancer (EC). METHODS This is a prospective cohort study of 3058 newly diagnosed EC cases from 1998 to 2010, identified through record linkages between the UK Clinical Practice Research Datalink, the National Cancer Research Datalink and death registrations from the Office of National Statistics. Using Cox regression models, unadjusted and adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated for EC-specific survival. RESULTS Over a mean 6.1 (range 1-16) years of follow-up, there were 394 EC-specific deaths. There was no evidence of a significant association between post-diagnostic use of statins (adjusted HR 0.83, 95% CI 0.64, 1.08), β-blockers (adjusted HR 0.86, 95% CI 0.65, 1.13) or low-dose aspirin (adjusted HR 0.91, 95% CI 0.69, 1.20) and EC survival before or after adjustment for confounders. There were also no evidence of a dose-response association between these drug groups and EC survival. CONCLUSIONS In this large UK population-based study, no significant associations were observed for post-diagnostic use of statins, β-blockers or low-dose aspirin and EC survival.

The Diagnostic Accuracy of Ultrasound in Assessment of Myometrial Invasion in Endometrial Cancer: Subjective Assessment versus Objective Techniques. BIOMED RESEARCH INTERNATIONAL 2017; 2017:1318203. [PMID: 28812010 PMCID: PMC5546069 DOI: 10.1155/2017/1318203] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/07/2017] [Revised: 05/02/2017] [Accepted: 05/23/2017] [Indexed: 01/02/2023]
Abstract
The aim of this study was to assess the diagnostic accuracy of subjective ultrasound evaluation of myometrial invasion of endometrial cancer and to compare its accuracy to objective methods. All consecutive patients with histologically proven endometrial cancer, who underwent ultrasound evaluation followed by surgical staging between January 2009 and December 2011, were prospectively enrolled. Myometrial invasion was evaluated by subjective assessment using ultrasound (<50% or ≥50%) and calculated as deepest invasion/normal myometrium ratio (Gordon's ratio) and as tumor/uterine anteroposterior diameter ratio (Karlsson's ratio). Histological assessment from hysterectomy was considered the gold standard. Altogether 210 patients were prospectively included. Subjective assessment and two objective ratios were found to be statistically significant predictors of the myometrial invasion (AUC = 0.65, p value < 0.001). Subjective assessment was confirmed as the most reliable method to assess myometrial invasion (79.3% sensitivity, 73.2% specificity, and 75.7% overall accuracy). Deepest invasion/normal myometrium (Gordon's) ratio (cut-off 0.5) reached 69.6% sensitivity, 65.9% specificity, and 67.3% overall accuracy. Tumor/uterine anteroposterior diameter (Karlsson's) ratio with the same cut-off reached 56.3% sensitivity, 76.4% specificity, and 68.1% overall accuracy. The subjective ultrasound evaluation of myometrial invasion performed better than objective methods in nearly all measures but showed statistically significantly better outcomes only in case of sensitivity.

Abstract
OBJECTIVES To evaluate the diagnostic and prognostic potential of preoperative serum CA-125 and HE4 levels in patients with endometrial cancer. METHODS Prospective case-control study of 133 women who underwent surgical treatment at the University Medical Centre Ljubljana (64 patients with endometrial cancer, 69 control patients with prolapsed uterus or myoma). Serum CA-125 and HE4 levels were determined using electrochemiluminescent assays. RESULTS Serum CA-125 and HE4 levels were significantly higher in patients with endometrial cancer, compared to the controls (p=2.67×10-4, 1.36×10-7, respectively). A diagnostic model that combines serum CA-125 and HE4 levels and body mass index separated patients with endometrial cancer from controls, with AUC of 0.804, sensitivity of 66.7%, and specificity of 84.6%. Serum HE4 levels showed good prognostic potential and stratified the patients according to presence/absence of deep myometrial invasion (p=0.001) or lymphovascular invasion (p=0.003), with AUCs of 0.78 and 0.81, respectively. In low-risk patients with grade 1 and 2 endometrioid cancer for whom lymphadenectomy can be avoided, HE4 allowed stratification according to deep myometrial invasion (p=3.39×10-4), with AUC of 0.84. Although median HE4 levels were higher in patients with lymphovascular invasion, this difference did not reach significance (p=0.06). CONCLUSIONS A model based on preoperative serum CA-125 and HE4 levels and body mass index has good diagnostic accuracy for separation of patients with endometrial cancer and control patients. In patients with endometrial cancer, serum HE4 levels allow prediction of deep myometrial and lymphovascular invasion.

Abstract
Cross-talk between estrogen receptor alpha (ERα) and signal transduction pathways plays an important role in the progression of endometrial cancer (EC). Here, we show that 17β-estradiol (E2) stimulation increases p21-activated kinase 4 (Pak4) expression and activation in ER-positive EC cells. The estrogen-induced Pak4 activation is mediated via the PI3K/AKT pathway. Estrogen increases Pak4 and phosphorylated-Pak4 (p-Pak4) nuclear accumulation, and Pak4 in turn enhances ERα trans-activation. Depletion or functional inhibition of Pak4 abrogates EC cell proliferation induced by E2, whereas overexpression of Pak4 rescues cell proliferation decreased by inhibiting the estrogen pathway. Pak4 knockdown decreases cyclin D1 expression and induces G1-S arrest. Importantly, Pak4 suppression inhibits E2 induced EC tumor growth in vivo, in a mouse xenograft model. These data demonstrate that estrogen stimulation increases Pak4 expression and activation, which in turn enhances ERα transcriptional activity and ERα-dependent gene expression, resulting in increased proliferation of EC cells. Thus inhibition of Pak4-ERα signaling may represent a novel therapeutic strategy against endometrial carcinoma.

Abstract
OBJECTIVE Carfilzomib is a second-generation tetrapeptide epoxyketone proteasome inhibitor used in current clinical therapy of hematologic malignancies. The mechanism of proteasome inhibition in endometrial cancer is not very clear. Carfilzomib inhibition of type I endometrial carcinoma cell proliferation by inducing cell cycle arrest at the G2/M phase was investigated in our study. MATERIALS AND METHODS HEC-1-A and Ishikawa endometrial carcinoma cell lines and three tumor cell lines were treated by different concentrations of carfilzomib. Methyl thiazolyl tetrazolium (MTT) assay was used to detect cell viability. Flow cytometry was used to analyze the cell cycle. Western blot was used to detect proteins involved in cell cycle progression. RESULTS Carfilzomib impaired viability of myelogenous leukemia cell line K562, cervical cancer cell line HeLa, hepatocellular carcinoma cell line SMCC-7721, and endometrial carcinoma cell lines HEC-1-A and Ishikawa. The cell cycle was arrested at the G2/M phase in carfilzomib-treated HEC-1-A endometrial carcinoma cells, while it was arrested at both S and G2/M phases in carfilzomib-treated Ishikawa cells. Carfilzomib treatment significantly induced p21Waf1/ Cip1 and p27, while substantially reduced cyclin D3 and cyclin-dependent kinase 1. CONCLUSION This study showed that carfilzomib inhibited endometrial cancer proliferation by upregulating cyclin-dependent kinase inhibitors p21Waf1/Cip1 and p27Kip1, and reducing cyclin-dependent kinase 1 to arrest the cell cycle at the G2/M phase.

Abstract
Globally, endometrial cancer is the sixth leading cause of female cancer-related deaths. Non-atypical endometrial hyperplasia (EH), has a lifetime progression rate to endometrial cancer ranging from less than 5%, if simple without atypia, to 40%, if complex with atypia. Site specific, long-acting intrauterine devices (IUDs) provide fertility sparing, progestin-based EH medical management. It is unclear which IUD is most beneficial, or if progesterone sensitizing metformin offers improved outcomes. For resolution, PubMed searches for “Mirena” or “Metformin,” “treatment,” “endometrial hyperplasia,” or “stage 1 endometrial cancer,” were performed, yielding 33 articles. Of these, 19 articles were included. The 60 mg high-dose frameless IUD/20 mcg levonorgestrel has achieved sustained regression of Grade 3 endometrial intraepithelial neoplasia for 14 years. Case series on early stage endometrial cancer (EC) treatment with IUDs have 75% or greater regression rates. For simple through complex EH with atypia, the 52 mg-IUD/10–20 mcg-LNG-14t has achieved 100% complete regression in 6-months. Clearly, IUDs have an outcome advantage over oral progestins. However, studies on metformin for EH, and of progestins or metformin for early stage EC management are underpowered, with inadequate dose ranges to achieve significant differences in, or optimal outcomes for, the treatment modalities. Therefore, outcomes from the feMMe trial for the 52 mg-IUD/10–20 mcg-LNG-14t and metformin will fill a gap in the literature.

Abstract
OBJECTIVE To evaluate the significance of postoperative inflammatory system response markers in predicting the prognosis of patients with endometrial cancer undergoing surgery. METHODS The present retrospective study included patients who underwent surgical treatment for pathology-confirmed endometrial cancer between January 1, 2007, and June 30, 2013, at the Affiliated Drum Tower Hospital, Nanjing University Medical School, Nanjing, China. Potential prognostic factors were investigated by Cox proportional hazards analysis and survival rates were compared using Kaplan-Meier analyses. RESULTS There were 185 patients with surgically treated endometrial cancer included. Multivariate analyses demonstrated that a preoperative neutrophil-to-lymphocyte ratio (NLR) above 1.81 (P=0.010) and a postoperative NLR above 7.54 (P=0.008) were both independently associated with lower disease free survival. Elevated preoperative and postoperative NLRs were associated with higher tumor stage (P=0.021 and P=0.009, respectively), and only elevated preoperative NLR was associated with lymph node involvement (P=0.023). CONCLUSION Preoperative and postoperative NLRs were independently associated with inflammatory system response markers and could be combined to evaluate the prognosis of patients with endometrial cancer following surgery.

Abstract
OBJECTIVES To analyze detection-rate(DR) and diagnostic-accuracy (A) of sentinel-nodes(SLNs) mapping following hysteroscopic-injection of tracer. To compare DR and A between tracers: ICG and Tc99m. METHODS Evaluation of endometrial-cancer patients who underwent SLNs mapping after hysteroscopic-peritumoral-injection of tracer±lymphadenectomy. Analysis of DR (overall-bilateral-aortic) and A in the entire cohort and comparison between tracers. RESULTS 202 procedures were performed from January/2005 to February/2017. Mean age:60years (28-82); mean BMI: 26.8 kg/m2 (15-47). In 133 cases (65.8%) hysterectomy and mapping procedure were performed laparoscopically. The overall-DR of the technique was 93.2% (179/192) (10 cases were excluded: 9 for technical-equipment failure; 1 for vagal reaction). Bilateral pelvic mapping was found in 59.7% of cases (107/179) and was more frequent in the ICG group (72.8% vs 53.3%; p: 0.012). In 50.8% of cases (91/179) SLNs were mapped both in pelvic and aortic nodes, and in 5 cases (2.8%) only in the aortic area. The mean number of detected SLNs was 3.7 (1-8). 22 patients (12.3%) had nodal involvement: 10-(45.5%)-macrometastases; 5-(22.7%)-micrometastases; 7-(31.8%)-ITCs. In 6 cases (27.3%) only aortic nodes were positive; in 5 cases (22.7%) both pelvic and aortic nodes and in 11 cases (50%) only pelvic nodes were involved. Three false-negative results were found, all in the Tc99m group. All had isolated aortic metastases with negative pelvic nodes. Overall-sensitivity was 86.4% (95%CI: 68.4-100) and overall-negative-predictive-value (NPV) was 96.4% (95%CI 86.7-100). No differences in terms of overall-DR, overall-sensitivity and overall-NPV were found between the two tracers. CONCLUSIONS Hysteroscopic-injection of tracer for SLNs mapping in endometrial cancer is as accurate as cervical injection with a higher DR in the aortic area. ICG improves bilateral-DR. Further investigation is warranted on this topic.

Abstract
Endometrial cancer is the most frequent gynecological malignancy in the developed world. The majority of cases are estrogen dependent, and are associated with diminished protective effects of progesterone. Endometrial cancer is also related to enhanced inflammation and decreased differentiation. In our previous studies, we examined the expression of genes involved in estrogen and progesterone actions in inflammation and tumor differentiation, in tissue samples from endometrial cancer and adjacent control endometrium. The aims of the current study were to examine correlations between gene expression and several demographic characteristics, and to evaluate changes in gene expression with regard to histopathological and clinical characteristics of 51 patients. We studied correlations and differences in expression of 38 genes involved in five pathophysiological processes: (i) estrogen-stimulated proliferation; (ii) estrogen-dependent carcinogenesis; (iii) diminished biosynthesis of progesterone: (iv) enhanced formation of progesterone metabolites; and (v) increased inflammation and decreased differentiation. Spearman correlation coefficient analysis shows that expression of PAQR7 correlates with age, expression of SRD5A1, AKR1B1 and AKR1B10 correlate with body mass, while expression of SRD5A1 and AKR1B10 correlate with body mass index. When patients with endometrial cancer were stratified based on menopausal status, histological grade, myometrial invasion, lymphovascular invasion, and FIGO stage, Mann-Whitney U tests revealed significantly decreased expression of STAR (4.4-fold; adjusted p=0.009) and AKR1B10 (9-fold; adjusted p=0.003) in high grade versus low grade tumors. Lower levels of STAR might lead to decreased de-novo steroid hormone synthesis and tumor differentiation, and lower levels of AKR1B10 to diminished elimination of toxic electrophilic carbonyl compounds in high-grade endometrial cancer. These data thus reveal the potential of STAR and AKR1B10 as prognostic biomarkers, which calls for further validation at the protein level.

Abstract
Endometrial cancer (EC) is the most common estrogen-dependent gynecological malignancy in the developed World. To investigate the local formation of estradiol (E2), we first measured the concentrations of the steroid precursor androstenedione (A-dione) and the most potent estrogen, E2, and we evaluated the metabolism of A-dione, estrone-sulfate (E1-S), and estrone (E1) in cancerous and adjacent control endometrium. Furthermore, we studied expression of the key genes for estradiol formation via the aromatase and sulfatase pathways. A-dione and E2 were detected in cancerous and adjacent control endometrium. In cancerous endometrium, A-dione was metabolized to testosterone, and no E2 was formed. Both, E1-S and E1 were metabolized to E2, with increased levels of E2 seen in cancerous tissue. There was no significant difference in expression of the key genes of the aromatase (CYP19A1) and the sulfatase (STS, HSD17B1, HSD17B2) pathways in cancerous endometrium compared to adjacent control tissue. The mRNA levels of CYP19A1 and HSD17B1 were low, and HSD17B14, which promotes inactivation of E2, was significantly down-regulated in cancerous endometrium, especially in patients with lymphovascular invasion. At the protein level, there were no differences in the levels of STS and HSD17B2 between cancerous and adjacent control tissue by Western blotting, and immunohistochemistry revealed intense staining for STS and HSD17B2, and weak staining for SULT1E1 and HSD17B1 in cancerous tissue. Our data demonstrate that in cancerous endometrium, E2 is formed from E1-S via the sulfatase pathway, and not from A-dione via the aromatase pathway.

Abstract
Nomegestrol acetate (NOMAC) has been successfully used for the treatment of some gynecological disorders, and as a combined oral contraceptive with approval in many countries. In this study, we investigated the effects of NOMAC on human endometrial cancer cells in vitro and in vivo. The proliferation of human endometrial cancer cells (RL95-2 and KLE) were assessed using CCK-8 and EdU incorporation assays. Whole-genome cDNA microarray analysis was used to identify the effects of NOMAC on gene expression profiles in RL95-2 cells. RL95-2 xenograft nude mice were treated with NOMAC (50, 100, and 200 mg/kg) or medroxyprogesterone acetate (MPA; 100 and 200 mg/kg) for 28 consecutive days. The results showed that NOMAC significantly inhibited the growth of RL95-2 cells in a concentration-dependent manner, but not in KLE cells. Further investigation demonstrated that NOMAC produced a stronger inhibition of tumor growth (inhibition rates for 50, 100, and 200 mg/kg NOMAC were 24.74%, 47.04%, and 58.06%, respectively) than did MPA (inhibition rates for 100 and 200 mg/kg MPA were 41.06% and 27.01%, respectively) in the nude mice bearing the cell line of RL95-2. NOMAC altered the expression of several genes related to cancer cell proliferation, including SUFU and Wnt7a. The upregulation of SUFU and Wnt7a was confirmed using real-time quantitative polymerase chain reaction and Western blotting in RL95-2 cells and RL95-2 xenograft tumor tissues, but not in KLE cells. These data indicate that NOMAC can inhibit the proliferation of RL95-2 cell in vitro and suppress the growth of xenografts in the nude mice bearing the cell line of RL95-2 in vivo. This effect could be related to the upregulating expression of SUFU and Wnt7a.

Abstract
Endometrial carcinoma (EC) is traditionally characterized as endometrioid and nonendometrioid based on histopathologic phenotypes. Molecular-based classifications have been proposed, but are not widely implemented. Herein we examine molecular profiles between EC histologic subtypes. 3133 ECs were submitted between March 2011 and July 2014: 1634 Type I and 1226 Type II. In situ hybridization and immunohistochemistry were used to assess copy number and protein expression of selected genes. Sequenced variants in 47 genes were analyzed using the Illumina TruSeq Amplicon Cancer Panel. Type II EC included 628 cases of uterine serous cancer (USC), 136 cases of clear cell (CC), 361 cases of carcinosarcoma (CS), 38 cases of mucinous, and 36 cases of squamous cell. PI3K/Akt/mTOR pathway was most frequently dysregulated within Type I and mucinous histologies, least altered in CS and squamous. PD-L1 expression was highest in mucinous, absent in squamous. ER/PR expression was common in Type II, most frequent in USC, mucinous, and squamous. Receptor tyrosine kinase was frequently dysregulated in Type II disease: HER2 amplification highest in USC and CC, EGFR mutations exclusively seen in mucinous EC, KRAS mutations common in mucinous, squamous, and Type I, and c-MET overexpression high in CC and mucinous. BRCA1 and BRCA2 were most frequently mutated in CS. Grade 3 EC shares features of G1 tumor and Type II disease, most notably resembling CS. Endometrial carcinomas are a molecularly heterogeneous group of tumors. A histology-based molecular map can identify rational targets to optimize treatment and guide future clinical trials.

Abstract
Growth Hormone may influence neoplastic development of endometrial epithelium towards endometrial adenocarcinoma, which is one of the most occurring tumors in acromegalic patients. Since chemoresistance often develops in advanced endometrial adenocarcinoma, we investigated whether Growth Hormone might influence the development of chemoresistance to drugs routinely employed in endometrial adenocarcinoma treatment, such as Doxorubicin, Cisplatin, and Paclitaxel. Growth Hormone and Growth Hormone receptor expression was assessed by immunofluorescence in two endometrial adenocarcinoma cell lines, AN3 CA and HEC-1-A cells. Growth Hormone effects were assessed investigating cell viability, caspase3/7 activation, ERK1/2, and protein kinase C delta protein expression. AN3 CA and HEC-1-A cells display Growth Hormone and Growth Hormone receptor. Growth Hormone does not influence cell viability in both cells lines, but significantly reduces caspase 3/7 activation in AN3 CA cells, an effect blocked by a Growth Hormone receptor antagonist. Growth Hormone rescues AN3 CA cells from the inhibitory effects of Doxorubicin and Cisplatin on cell viability, while it has no effect on Paclitaxel. Growth Hormone does not influence the pro-apoptotic effects of Doxorubicin, but is capable of rescuing AN3 CA cells from the pro-apoptotic effects of Cisplatin. On the other hand, Growth Hormone did not influence the effects of Doxorubicin and Paclitaxel on HEC-1A cell viability. The protective action of Growth Hormone towards the effects of Doxorubicin may be mediated by ERK1/2 activation, while the pro-apoptotic effects of Cisplatin may be mediated by protein kinase C delta inhibition. All together our results indicate that Growth Hormone may differentially contribute to endometrial adenocarcinoma chemoresistance. This may provide new insights on novel therapies against endometrial adenocarcinoma chemoresistant aggressive tumors.

Abstract
OBJECTIVES Compliance of physicians with guidelines has emerged as an important indicator for quality of care. We evaluated compliance of physicians with adjuvant therapy guidelines for endometrial cancer patients in the Netherlands in a population-based cohort over a period of 10years. METHODS Data from all patients diagnosed with endometrial cancer between 2005 and 2014, without residual tumor after surgical treatment, were extracted from the Netherlands Cancer Registry (N=14,564). FIGO stage, grade, tumor type and age were used to stratify patients into risk groups. Possible changes in compliance over time and impact of compliance on survival were assessed. RESULTS Patients were stratified into low/low-intermediate (52%), high-intermediate (21%) and high (20%) risk groups. Overall compliance with adjuvant therapy guidelines was 85%. Compliance was highest in patients with low/low-intermediate risk (98%, no adjuvant therapy indicated). The lowest compliance was determined in patients with high risk (61%, external beam radiotherapy with/without chemotherapy indicated). Within this group compliance decreased from 64% in 2005-2009 to 57% in 2010-2014. In high risk patients with FIGO stage III serous disease compliance was 55% (chemotherapy with/without radiotherapy indicated) and increased from 41% in 2005-2009 to 66% in 2010-2014. CONCLUSION While compliance of physicians with adjuvant therapy guidelines is excellent in patients with low and low-intermediate risk, there is room for improvement in high risk endometrial cancer patients. Eagerly awaited results of ongoing randomized clinical trials may provide more definitive guidance regarding adjuvant therapy for high risk endometrial cancer patients.

Abstract
Carcinogenesis is a multistep multifactorial process that involves the accumulation of genetic and epigenetic alterations. In the past two decades, there has been an exponential growth of knowledge establishing the importance of epigenetic changes in cancer. Our work focused on reviewing the main role of epigenetics in the pathogenesis of endometrial carcinoma, highlighting the reported results concerning each epigenetic mechanistic layer. The present review is the first part of this work, in which we examined the contribution of DNA methylation alterations for endometrial carcinogenesis.

Abstract
Risk grouping for treatment and follow-up strategy of early stage endometrial cancer is confusing to apply in clinical conditions. We investigated the stage-based prognostic factors for tumor recurrence in stage I endometrial cancer with endometrioid histology (EEC).The medical records of women diagnosed with endometrial adenocarcinoma between 1993 and 2013 were retrospectively reviewed. In 521 patients with International Federation of Gynecology and Obstetrics (FIGO) stage I EEC were included. The baseline patient characteristics were analyzed with the chi-square test and Fisher's exact tests. A multivariate analysis with a Cox proportional hazard model and logistic regression were performed to identify the prognostic factors for recurrence-free survival (RFS) in FIGO stage I EEC.The median follow-up period for the included patients was 74.6 months (3.1-264.9 months). Tumor recurrence occurred in 30 patients (5.8%) with a median time span of 22.85 months (2.2-124.7 months). Only 2 factors among the conventional adverse risk factors, including myometrial invasion and histologic grade, affected tumor recurrence in stage I EEC (P = .003 and P = .003, respectively). Myometrial invasion was an independent prognostic factor for RFS in stage IA EEC via multivariate analysis (P = .005). In stage IB EEC, the histologic grade was an independent prognostic factor for RFS. The median RFS of stage IB EEC was 156.0 months in grade 1, 120.0 months in grade 2, and 105.9 months in grade 3 (P = .006).Within stage I EEC, the prognostic factors for tumor recurrence were different between stages IA and IB. Myometrial invasion comprised the prognostic factor in stage IA, whereas the histologic grade comprised the prognostic factor in stage IB.

Abstract
BACKGROUND In the staging of endometrial cancer, controversy remains regarding the role of sentinel lymph node mapping compared with other nodal assessment strategies. OBJECTIVE We conducted a systematic review to evaluate the diagnostic accuracy and clinical impact of sentinel lymph node mapping in the management of endometrial cancer. DATA SOURCES We searched Medline, Embase, and the Cochrane Central Registry of Controlled trials for studies published in English before March 25, 2016 (PROSPERO CRD42016036503). STUDY ELIGIBILITY CRITERIA Studies were included if they contained 10 or more women with endometrial cancer and reported on the detection rate, sensitivity, and/or impact on treatment or survival of sentinel lymph node mapping. STUDY APPRAISAL AND SYNTHESIS METHODS Two authors independently reviewed abstracts and full-text articles for inclusion and assessed study quality. The detection rate, sensitivity, and factors associated with successful mapping (study size, body mass index, tumor histology and grade, injection site, dye type) were synthesized through random-effects meta-analyses and meta-regression. RESULTS We identified 55 eligible studies, which included 4915 women. The overall detection rate of sentinel lymph node mapping was 81% (95% confidence interval, 77-84) with a 50% (95% confidence interval, 44-56) bilateral pelvic node detection rate and 17% (95% confidence interval, 11-23) paraaortic detection rate. There was no difference in detection rates by patient body mass index or tumor histology and grade. Use of indocyanine green increased the bilateral detection rate compared with blue dye. Additionally, cervical injection increased the bilateral sentinel lymph node detection rate but decreased the paraaortic detection rate compared with alternative injection techniques. Intraoperative sentinel lymph node frozen section increased the overall and bilateral detection rates. The sensitivity of sentinel node mapping to detect metastases was 96% (95% confidence interval, 91-98); ultrastaging did not improve sensitivity. Compared with women staged with complete lymphadenectomy, women staged with sentinel lymph node mapping were more likely to receive adjuvant treatment. CONCLUSION Sentinel lymph node mapping is feasible and accurately predicts nodal status in women with endometrial cancer. The current data favors the use of cervical injection techniques with indocyanine green. Sentinel lymph mapping may be considered an alternative standard of care in the staging of women with endometrial cancer.

Abstract
Endometrial cancer is often characterized by PI3K/AKT pathway deregulation. Recently it has been suggested that SGK1, a serine/threonine protein kinase that shares structural and functional similarities with the AKT family, might play a role in cancer, since its expression and/or activity has been found to be deregulated in different human tumors. However, the role of SGK1 in endometrial cancer has been poorly investigated. Here, we show that SGK1 expression is increased in tissue specimens from neoplastic endometrium. The SGK1 inhibitor SI113 induced a significant reduction of endometrial cancer cells viability, measured by the (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide assay. This effect was associated to the increase of autophagy, as revealed by the increase of the markers LC3B-II and beclin I, detected by both immunofluorescence and western blot analysis. SI113 treatment caused also apoptosis of endometrial cancer cells, evidenced by the cleavage of the apoptotic markers PARP and Caspase-9. Intriguingly, these effects were associated to the induction of endoplasmic reticulum stress markers GRP78 and CHOP evaluated by both Real-Time RT-PCR and Western Blot analysis. Increased expression of SGK1 in endometrial cancer tissues suggest a role for SGK1 in this type of cancer, as reported for other malignancies. Moreover, the efficacy of SI113 in affecting endometrial cancer cells viability, possibly via endoplasmic reticulum stress activation, identifies SGK1 as an attractive molecular target for new tailored therapeutic intervention for the treatment of endometrial cancer.

Abstract
Sex‐determining region Y‐box 2 (SOX2) is an essential factor involved in the self‐renewal and pluripotency of embryonic stem cells and has functions in cell survival and progression in many types of cancers. Here, we found that several endometrial cancer cell lines expressed SOX2, which was required for cell growth. Additionally, SOX2 overexpression regulated the expression of cyclin‐dependent kinase inhibitor 1A (CDKN1A), and SOX2 specifically bound to p21 promoter DNA in endometrial cancer cell lines expressing SOX2. Expressions of SOX2 in endometrial cancer patients were significantly correlated with histological grade and poor prognosis. Moreover, low p21 together with high SOX2 expressions in advanced endometrial cancer patients were associated with the most unfavorable outcomes of patients. These results indicated that simultaneous measurement of SOX2 and p21 expression in endometrial cancer patients may be a useful biomarker for patient prognosis.

Abstract
PURPOSE Endometrial cancer can be divided into two types: endometrioid Type 1 (G1, G2) has a hormonal driven etiology, while Type 2 is more aggressive (G3 endometrioid, clear cell and serous cancer type) and estrogen independent. We noticed an increase of more aggressive G3 endometrioid endometrial adenocarcinomas. This observation is of relevance for daily clinical practice because therapy depends on the histopathological grading and myometrial invasion. G3 cancers or myometrial invasion of more than 50% should be hysterectomized including bilateral adnexectomy with pelvine and paraaortal lymphadenectomy. In G1/G2 and lower infiltration levels, hysterectomy with adnexectomy without lymphadenectomy is sufficient. METHODS Data of the ASF Statistic were used to analyze the changes in the incidences of patients with endometrioid cancer, grading groups and their first diagnosed stages between 2006 and 2014. RESULTS 2611 patients, with 243-341 women per year, were analyzed. The number of diagnosed G1 tumors increased from 25 to 37% and the G3 tumors from 18 to 32%, whereas the G2 cancers decreased from 58 to 31%. Despite the rise of G3 tumors, an increase in age at diagnosis was not observed. The proportions of initial diagnosed stages (FIGO I-IV) in each grading remained constant over time. CONCLUSION Potential consequences in treatment recommendations and prognosis urge attention to the detected increase of G3 endometrioid cancers.

Abstract
In humans, the endometrium, the uterine mucosal lining, undergoes dynamic changes throughout the menstrual cycle and pregnancy. Despite the importance of the endometrium as the site of implantation and nutritional support for the conceptus, there are no long-term culture systems that recapitulate endometrial function in vitro. We adapted conditions used to establish human adult stem cell-derived organoid cultures to generate 3D cultures of normal and decidualised human endometrium. These organoids expand long-term, are genetically stable and differentiate following treatment with reproductive hormones. Single cells from both endometrium and decidua can generate a fully functional organoid. Transcript analysis confirmed great similarity between organoids and the primary tissue of origin. On exposure to pregnancy signals, endometrial organoids develop characteristics of early pregnancy. We also derived organoids from malignant endometrium, and so provide a foundation to study common diseases, such as endometriosis and endometrial cancer, as well as the physiology of early gestation.

Abstract
Historically associated with the aetiology of human leukaemia, the runt-related transcription factor 1 (RUNX1) gene has in recent years reared its head in an assortment of epithelial cancers. This review discusses the state-of-the-art knowledge of the enigmatic role played by RUNX1 in female-related cancers of the breast, the uterus and the ovary. The weight of evidence accumulated so far is indicative of a very context-dependent role, as either an oncogene or a tumour suppressor. This is corroborated by high-throughput sequencing endeavours which report different genetic alterations affecting the gene, including amplification, deep deletion and mutations. Herein, we attempt to dissect that contextual role by firstly giving an overview of what is currently known about RUNX1 function in these specific tumour types, and secondly by delving into connections between this transcription factor and the physiology of these female tissues. In doing so, RUNX1 emerges not only as a gene involved in female sex development but also as a crucial mediator of female hormone signalling. In view of RUNX1 now being listed as a driver gene, we believe that greater knowledge of the mechanisms underlying its functional dualism in epithelial cancers is worthy of further investigation.

Abstract
BACKGROUND The non-invasive diagnostic approach for early detection of endometrial cancer (EC) remains limited. To date, human epididymis protein 4 (HE4) has been intensively studied but its diagnostic is controversial in EC. DJ-1 is an oncoprotein secreted by cancer cells, recently identified as a potential diagnostic biomarker for breast cancer, melanoma, and pancreatic cancer. The aim of this study was to compare the diagnostic performances of DJ-1 and HE4 measured in EC patients and healthy controls (HC). METHODS Forty-five patients (63.9±12.0 years) with EC and 29 (63.2±13.3 years) HC were enrolled. Serum concentrations of DJ-1 and HE4 were measured using ELISA kits developed by R&D (Minneapolis, USA) and Fujirebio Diagnostic (Malvern, PA, USA), respectively. Differences between EC patients and HC were assessed by Mann-Whitney test and associations were tested by Spearman's correlation. The diagnostic performance was assessed using receiver operating characteristics (ROC) curves analysis. RESULTS Serum DJ-1 concentrations were found to be higher in EC patients than in HC (9533.6 vs 1988.5 pg/mL; P<.0001). The area under the ROC curve (ROC-AUC) was 0.95 (P<.0001). At the cut-off of 3654 pg/mL, the sensitivity and specificity were 0.89 and 0.90, respectively. HE4 serum levels were higher in EC patients than in HC (75.3 vs 56.2 pmol/L; P=.019), with an AUC of 0.66 (P=.020). The AUC obtained by the combination of the two markers resulted 0.96 (P<.0001). CONCLUSION These results suggest that increased serum DJ-1 levels are associated with EC and that this biomarker may be potentially useful for diagnosing EC.

Abstract
OBJECTIVES The purpose of this study was to analyse the clinical impact of LVSI status in a large French multicentre cohort of women with high-risk ECs according to the ESMO classification. METHODS Data of 258 women with high-risk EC who received primary surgical treatment between January 2001 and December 2012 were abstracted from prospective multicentre database. The end points were the recurrence and the lymph node metastasis (LNM) rates. Recurrence free survival (RFS) and overall survival (OS) were analyzed. RESULTS The recurrence and LNM rates in the whole population were 32.9% and 34.5%, respectively. The median follow-up and initial recurrence times were 27 (range: 1-151) and 23.5 (range: 1-151) months, respectively. The respective 3-year RFS rates according to the LNM and LVSI status were, 78.3% (95% CI, 70.1-87.3), 53.7% (95% CI, 40.8-70.6), 65.5% (95% CI, 46.1-93.2), 43.5% (95% CI, 30.3-62.3) for women with no LN metastasis/no LVSI; no LN metastasis/LVSI present; LN metastasis/no LVSI; LN metastasis/LVSI present, respectively (p = 0.0005). CONCLUSIONS LVSI status remains a strong prognostic factor in high-risk ECs associated with a higher recurrence rate and lower RFS and OS whatever the histological type and lymph node status. It could thus be considered in future trials to guide decision-making about adjuvant therapy in high-risk ECs.

Abstract
OBJECTIVE To examine the long-term effects of bariatric surgery on female-specific cancer in women with obesity. METHODS The prospective, matched Swedish Obese Subjects (SOS) study was designed to examine outcomes after bariatric surgery. This study includes 1420 women from the SOS cohort that underwent bariatric surgery and 1447 contemporaneously matched controls who received conventional obesity treatment. Age was 37-60years and BMI was ≥38kg/m2. Information on cancer events was obtained from the Swedish National Cancer Registry. Median follow-up time was 18.1years (interquartile range 14.8-20.9years, maximum 26years). This study is registered with ClinicalTrials.gov, NCT01479452. RESULTS Bariatric surgery was associated with reduced risk of overall cancer (hazard ratio=0.71; 95% CI 0.59-0.85; p<0.001). About half of the observed cancers were female-specific, and the incidence of these were lower in the surgery group compared with the control group (hazard ratio=0.68; 95% CI 0.52-0·88; p=0.004). The surgical treatment benefit with respect to female-specific cancer was significantly associated with baseline serum insulin (interaction p value=0.022), with greater relative treatment benefit in patients with medium or high insulin levels. Separate analyses of different types of female-specific cancers showed that bariatric surgery was associated with reduced risk of endometrial cancer (hazard ratio=0.56: 95% CI 0.35-0.89; p=0.014). CONCLUSIONS In this long-term study, bariatric surgery was associated with reduced risk of female-specific cancer, especially in women with hyperinsulinemia at baseline.

Abstract
PURPOSE: To investigate the prognostic value of preoperative intratumoral 18F-FDG uptake heterogeneity (IFH) derived from positron emission tomography (PET)/computed tomography (CT) in patients with endometrioid endometrial cancer. METHODS: We retrospectively evaluated clinicopathological data from patients with pathologically proven endometrioid endometrial cancer who had undergone 18F-FDG PET/CT scans before surgery. Patients were divided into two groups according to their IFH. The main outcome measure was disease-free survival (DFS). RESULTS: Between January 2010 and January 2015, data from 72 patients were available for analysis. The median duration of DFS was 23 months (range, 6 to 57 months), and 4 (5.6%) patients experienced recurrence. There were significant differences in tumor size, IFH, and DFS between patients with and without recurrence. In regression analysis, high IFH value [P = .007, hazard ratio (HR) 2.545, 95% confidence interval (CI) 1.468-8.674] was the only independent risk factor for recurrence. The Kaplan-Meier survival graphs showed that DFS significantly differed in groups categorized based on IFH (P < .001, log-rank test). CONCLUSIONS: Preoperative IFH measured by 18F-FDG PET/CT was associated with recurrence of endometrioid endometrial cancer. The finding supports evidence that FDG-based heterogeneity can be a novel and useful predictor of endometrioid endometrial cancer recurrence.

Abstract
The inflammatory response is known to have a significant role in certain autoimmune diseases and malignancies. We review current knowledge regarding the functions of activator protein 1 (AP-1) as an important modulator in several immune disorders and carcinomas. AP-1 is overexpressed in rheumatoid arthritis and in long-term allogeneic hematopoietic stem cell transplantation survivors; however, decreased expression of AP-1 has been observed in psoriasis, systematic lupus erythematosus and in patients who do not survive after hematopoietic stem cell transplantation. AP-1 also is implicated in the control of various cancer cells. Higher levels of AP-1 components are present in breast and endometrial carcinomas, colorectal cancer and in acute myeloid leukemia, Hodgkin׳s lymphoma and anaplastic large cell lymphoma, with downregulation in ovarian and gastric carcinomas and in patients with chronic myelogenous leukemia. AP-1 may enable the development of helpful markers to identify early-stage disease or to predict severity.

Abstract
We report a case of necrotising fasciitis caused by metastatic endometrial adenocarcinoma. Metastases to the lumbar spine with local invasion to the iliopsoas muscle led to an iliopsoas abscess, which subsequently progressed to necrotising fasciitis of the flank. This patient lacked common risk factors for necrotising fasciitis. There are no previous reports in the literature of necrotising fasciitis with this aetiology. We discuss the available evidence for aetiology of and risk factors for necrotising fasciitis, and the relation of time to surgery with prognosis.

Cholesterol Synthetase DHCR24 Induced by Insulin Aggravates Cancer Invasion and Progesterone Resistance in Endometrial Carcinoma. Sci Rep 2017; 7:41404.

Abstract
3β-Hydroxysteroid-Δ24 reductase (DHCR24), the final enzyme of the cholesterol biosynthetic pathway, has been associated with urogenital neoplasms. However, the function of DHCR24 in endometrial cancer (EC) remains largely elusive. Here, we analyzed the expression profile of DHCR24 and the progesterone receptor (PGR) in our tissue microarray of EC (n = 258), the existing EC database in GEO (Gene Expression Omnibus), and TCGA (The Cancer Genome Atlas). We found that DHCR24 was significantly elevated in patients with EC, and that the up-regulation of DHCR24 was associated with advanced clinical stage, histological grading, vascular invasion, lymphatic metastasis, and reduced overall survival. In addition, DHCR24 expression could be induced by insulin though STAT3, which directly binds to the promoter elements of DHCR24, as demonstrated by ChIP-PCR and luciferase assays. Furthermore, genetically silencing DHCR24 inhibited the metastatic ability of endometrial cancer cells and up-regulated PGR expression, which made cells more sensitive to progestin. Taken together, we have demonstrated for the first time the crucial role of the insulin/STAT3/DHCR24/PGR axis in the progression of EC by modulating the metastasis and progesterone response, which could serve as potential therapeutic targets for the treatment of EC with progesterone receptor loss.

Urocortin suppresses endometrial cancer cell migration via CRFR2 and its system components are differentially modulated by estrogen. Cancer Med 2017; 6:408-415.

Abstract
Urocortin (UCN1) peptide shares structural and functional homology with corticotropin‐releasing factor (CRF). UCN1 is significantly reduced in endometrial adenocarcinoma compared to healthy controls. However, there are no data which evaluate the effects of UCN1 in the endometrium, or how it is modulated. We used proliferation and transwell assays to determine the effect of UCN1 on the proliferation and migration of Ishikawa and HEC1A cells. We also determined the expression levels of UCN1 and its receptors produced by estrogen receptor agonists, and the effect of UCN1 on estrogen receptor expression, using quantitative polymerase chain reaction. UCN1 suppressed migration of endometrial cancer cells in vitro. This effect appears to be specific to CRF receptor 2 (CRFR2), as selective antagonism of CRFR2 but not CRFR1 completely eliminated suppression of migration. Activation of ERA reduced UCN1 expression, but only had a small effect on the expression of CRFR1. However, expression of CRFR2 was more notably reduced at both the mRNA and protein levels by activation of ERB. UCN1 in turn reduced both ERA and ERB expression, as assessed by real‐time quantitative PCR. We demonstrate that UCN1 significantly suppresses the migration of endometrial cancer cells but has no effect on their proliferation. Thus, loss of UCN1 in endometrial cancer may promote invasion and metastatic spread. There is a complex relationship between the UCN1 system and estrogen receptors, which may provide insights into endometrial carcinogenesis, a disease known to be driven by estrogen excess.

Abstract
Robotic-assisted surgery is a technological advancement that facilitates the application of minimally invasive techniques for complex operations in gynecologic oncology. The objective of this article was to review the literature regarding the role of robotic-assisted surgery to treat women with gynecologic cancers. The majority of publications on robotic surgery are still retrospective or descriptive in nature; however, the data for managing patients with a robotic-assisted approach show comparable, and at times improved, outcomes compared with both laparoscopy (2-dimensional) and laparotomy approaches. Robotic-assisted surgery has been used for patients with endometrial cancer and resulted in the increased use of minimally invasive surgery with improved outcomes compared with laparotomy and partially with laparoscopy. This has been shown in large cohorts of patients as well as in obese patients in whom the complication rates have significantly decreased. For early cervical cancer, robotic radical hysterectomy seems to be safe and feasible and to be preferable to laparotomy with seemingly comparable oncologic outcomes. Robotic-assisted surgery and conventional laparoscopy to stage women with early-stage ovarian cancer seem to have similar surgical and oncologic outcomes, with a shorter learning curve for robotic-assisted surgery. However, robotic-assisted surgery appears to be more expensive than laparotomy and traditional laparoscopy. In conclusion, robotic-assisted surgery appears to facilitate the surgical approach for complex operations to treat women with gynecologic cancers. Although randomized controlled trials are lacking to further elucidate the equivalence of robot-assisted surgery with conventional methods in terms of oncologic outcome and patients' quality of life, the technology appears to be safe and effective and could offer a minimally invasive approach to a much larger group of patients.

Abstract
Background Targeting BRAF V600E mutation has been proven effective in the treatment of several types of cancer. In endometrial adenocarcinoma, the BRAF V600E mutation has been rarely reported. Whether targeting BRAF oncogene may represent a plausible therapeutic strategy for the rare patients with BRAF-mutated endometrial cancer remains to be ascertained in prospective studies. Case presentation We report herein the case of a heavily pre-treated patient with recurrent microsatellite instability high (MSI-H) BRAF V600E mutated endometrial adenocarcinoma, which was successfully treated with the V600E targeting agent dabrafenib. After developing resistance to this agent, the MEK targeting agent trametinib was added to dabrafenib achieving again a therapeutic response. Conclusions This case shows that dabrafenib both as monotherapy and when combined with trametinib may exert significant therapeutic activity in heavily pretreated BRAF V600E mutated endometrial adenocarcinoma, and highlight potential benefits of personalized treatment in this disease.

Abstract
Endometrial carcinoma (EC) is the fourth most common cancer in women in the developed world. Classification of ECs by histomorphologic criteria has limited reproducibility and better tools are needed to distinguish these tumors and enable a subtype-specific approach to research and clinical care. Based on the Cancer Genome Atlas, two research teams have developed pragmatic molecular classifiers that identify four prognostically distinct molecular subgroups. These methods can be applied to diagnostic specimens (e.g., endometrial biopsy) with the potential to completely change the current risk stratification systems and enable earlier informed decision making. The evolution of genomic classification in ECs is shared herein, as well as potential applications and discussion of the essential research still needed in order to optimally integrate molecular classification in to current standard of care.

Abstract
Robotic surgery is the most dynamic development in the sector of minimally invasive operations currently. It should not be viewed as an alternative to laparoscopy, but as the next step in a process of technological evolution. The advancement of robotic surgery, in terms of the introduction of the Da Vinci Xi, permits the variable use of optical devices in all four trocars. Due to the new geometry of the "patient cart," an operation can be performed in all spatial directions without re-docking. Longer instruments and the markedly narrower mechanical elements of the "patient cart" provide greater flexibility as well as access similar to those of traditional laparoscopy. Currently, robotic surgery is used for a variety of indications in the treatment of benign gynecological diseases as well as malignant ones. Interdisciplinary cooperation and cooperation over large geographical distances have been rendered possible by telemedicine, and will ensure comprehensive patient care in the future by highly specialized surgery teams. In addition, the second operation console and the operation simulator constitute a new dimension in advanced surgical training. The disadvantages of robotic surgery remain the high costs of acquisition and maintenance as well as the laborious training of medical personnel before they are confident with using the technology.

Abstract
OBJECTIVE To explore risk factors associated with sampling failure in women who underwent Pipelle biopsy. METHODS A consecutive sample of 201 patient records was selected from women who underwent Pipelle biopsy procedures for suspected uterine pathology in a large healthcare system over a 6-month period (January 2013 through June 2013). Personal and medical data including age, BMI, gravidity and parity, and previous history of Pipelle biopsy were abstracted from medical records for each patient. Logistic regression analyses were used to determine factors associated with biopsy sampling failure. RESULTS Pipelle biopsy sampling failed in 46 out 201 women (22.89%), where 8 (17.39%) were due to inability to access the endometrium, 37 (80.43%) were inadequate samples, and 1 (2.18%) was due to unknown reasons. Personal and medical factors found to be related to sampling failure included: postmenopausal bleeding as biopsy indication (OR 7.41, 95% CI 2.27-24.14); history of prior biopsy failure (OR 23.87, 95% CI 3.76-151.61); and provider type (physician vs. midlevel provider) (OR 9.152, 95% CI 2.49-33.69). CONCLUSION We identified several risk factors for biopsy failure that suggest the need for particular care with Pipelle sampling procedures among women with certain characteristics, including postmenopausal bleeding and a history of prior failed Pipelle biopsy. Our finding of a significantly higher risk of sampling failure based on personal and clinical data suggests that providers must take into account additional considerations to improve sampling success.

Abstract
OBJECTIVE This study aims to evaluate the different surgical approaches, perioperative morbidity and surgical staging according to age in patients with endometrial cancer. METHODS Multicentre retrospective study. Cancer characteristics and perioperative data were collected for patients surgically treated for endometrial cancer. The patients were divided into 2 groups according to their age: younger or older than 75 years. RESULTS Surgery was performed on 270 women <75 years old and on 74 ≥ 75 years old. Minimally invasive surgery was performed less often in the elderly compared with their younger counterparts (58.2% vs. 74.8%; p = 0.006). Independently of the surgical approach, the rate of pelvic and para-aortic lymphadenectomy was lower in women older than 75 years old than their younger counterparts (52.7% vs. 74.8%; p < 0.001; 8.1% vs. 21.8%; p = 0.007 respectively). According to the guidelines, more frequent surgical understaging was seen in the elderly compared with the younger (37% vs. 15.2%; p = 0.002). In the comparison of complications for each surgical approach, there was no statistical difference in the ≥75-year-old age group in terms of intra- or postoperative complications between the laparotomy, laparoscopy or robotic surgery group. We found a shorter length of hospital stay for the women who underwent laparoscopy or robotic surgery compared with laparotomy (p < 0.0001). CONCLUSION Elderly women with endometrial cancer are often surgically understaged whereas there is no evidence of greater perioperative complications than for their younger counterparts. They should benefit from minimally invasive surgery and optimal surgical staging to the same extent as younger women.

Establishment and characterization of a novel uterine carcinosarcoma cell line, TU-ECS-1, with mutations of TP53 and KRAS. Hum Cell 2016; 30:140-148. [PMID: 27889902 DOI: 10.1007/s13577-016-0154-6] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2016] [Accepted: 11/14/2016] [Indexed: 10/20/2022]
Abstract
A new human uterine carcinosarcoma (UCS) cell line, TU-ECS-1, was established and characterized. The morphological appearance of the cultured cells was an insular of epithelial-like cells arranged in the form of a jigsaw puzzle and mesenchymal-like cells with a spindle-shaped or fibroblast-like morphology. A relatively high proliferation rate was observed with a doubling time of 18.2 h. The chromosome number ranged from 44 to 49 and had an extra chromosome 12 (trisomy 12). The respective half-maximal inhibitory concentrations of cisplatin, paclitaxel, and doxorubicin were 2.9 µM, 154 nM, and 219 ng/mL, respectively. Mutational analysis revealed that TU-ECS-1 cells have mutations of TP53 in exons 4, 6, and 8 and of KRAS at codon 12 (G12D) in exon 2, which is a mutation hot spot on this gene. Western blot analysis showed that p53 protein was overexpressed in TU-ECS-1 cells. Immunostaining of the cultured cells and in vivo tumors showed that the TU-ECS-1 cells and xenografts were positive for epithelial marker cytokeratin AE1/3 and mesenchymal marker vimentin. These results suggested that TU-ECS-1 cells might have both epithelial and mesenchymal characteristics. This cell line may be useful to study the carcinogenesis of UCS and contribute to the development of novel treatment strategies.

Abstract
BACKGROUND The purpose of this study was to develop a nomogram to predict 'poor prognosis recurrence' (PPR) in women treated for endometrial cancer (EC). METHODS The data of 861 women who received primary surgical treatment between January 2001 and December 2013 were abstracted from a prospective multicenter database. Data were randomly split into two sets: training and validation with a predefined 2/3 ratio. A Cox proportional hazards multivariate model of selected prognostic features was performed in the training cohort (n=574) to develop a nomogram predicting PPRs. The nomogram was validated in the validation cohort of 287 patients. RESULTS In the training cohort, 82 (14.3%) developed subsequent PPR. Age, histologic type and grade, lymphovascular space invasion status, FIGO stage, and nodal staging (SLN±pelvic and/or para-aortic lymphadenectomy) were independently associated with subsequent PPR. The nomogram showed an area under the receiver operating characteristic curve (AUC) of 0.82 (95% confidence interval (CI), 0.73-0.89) in the training set. The validation set showed a good discrimination with an AUC of 0.75 (95% CI, 0.65-0.83). CONCLUSIONS We have developed a robust tool that is able to predict subsequent PPRs in women with FIGO I-III EC.

Abstract
OBJECTIVE To evaluate the predictive value of serum HE4 and CA125 concentrations in the preoperative prediction of risk of lymph node metastasis in endometrial cancer. METHODS A retrospective study was undertaken of data for patients with endometrial carcinoma treated surgically at a university hospital in China between August 2011 and December 2015. The preoperative serum levels of HE4 and CA125 were measured and analyzed by clinicopathologic characteristics. RESULTS Overall, 258 patients were included. The HE4 and CA125 concentrations were significantly elevated in patients with large lesions (≥2 cm), deep myometrial invasion (≥50%), an advanced disease stage, or lymph node metastasis (P<0.05 for all). HE4 concentrations also rose with age and histologic grade (P<0.01 for both). For lymph node metastasis, HE4 had higher sensitivity and negative predictive value than did CA125. The diagnostic performance of HE4 and CA125 in combination was superior to that of either marker alone. CONCLUSION The combined evaluation of serum HE4 and CA125 could provide gynecologic oncologists with improved information to guide the decision of whether to perform lymphadenectomy.

Abstract
Malignancies of the uterus metastasize by direct invasion of neighboring structures, lymphatically or hematogenously. Endometrial and cervical cancers lymphatically spread to the pelvic and para-aortic lymph nodes. For endometrial cancer the depth of myometrial invasion, lymphosvascular space involvement (LVSI) and a microcystic, elongated and fragmented (MELF) glandular invasion pattern are predictors for lymph node metastases. Metastases to the pelvic lymph nodes occur in approximately 10 % of endometrial cancer patients and in 30 % of these cases the para-aortic lymph nodes are also involved. Sentinel lymph node biopsy is possible for clinical stage I endometrial cancer and early stages of cervical cancer but is not yet routine. The presence of LVSI is considered to be the strongest predictor of distant metastases, particularly if assessed by immunohistochemistry with antibodies against factor VIII-related antigen or CD31. Endometrioid and clear cell carcinomas can hematogenously metastasize to the lungs, bones, liver and brain and can rarely be manifested as a solitary metastasis. In contrast, serous carcinomas can show extensive peritoneal spread. To date molecular biomarkers cannot predict the occurrence of distant metastasis. Overexpression of P53, p16 and L1CAM have been identified as negative prognostic factors and are associated with the prognostically unfavorable serous tumor type. The metastatic spread of squamous cell cervical cancer is strongly associated with tumor volume. Microinvasive carcinomas have a very low rate of parametrial and lymph node involvement and do not require radical hysterectomy. In contrast, lymph node metastases occur in up to 50 % of bulky stages IB and II cervical cancers. Distant metastases can occur in the lungs, liver, bones and brain. Molecular biomarkers have not been shown to predict metastatic spread. In well-differentiated adenocarcinoma of the cervix the pattern of invasion is strongly predictive for the presence of lymph node metastases, irrespective of tumor size and depth of invasion.
