Abstract
Endometriosis is an inflammatory disease and nuclear receptors play a crucial role in mediating the inflammatory response. In endometrial stromal cells (ESC), nuclear receptors expression can be influenced by the local environment. Progestins are first-line, on-label treatments of endometriosis that may have direct effects on endometriotic lesions through these nuclear receptors. Therefore, we investigated whether there was an association between nuclear receptors expression and the influence of progestins on inflammatory cytokines production in a preliminary, in vitro study with primary cultures. ESC from endometrial biopsies of six subjects with histologically confirmed endometriosis were treated for 6 h with medium alone or with TNF-α (10 or 100 ng/ml) in the presence of dienogest (DNG), medroxyprogesterone acetate (MPA) and norethisterone acetate (NETA) 10-5 M. The progestin-mediated change in IL6, IL8 and MCP-1 mRNA transcription was measured, as was the PRA, PRB, GR, AR and MCR protein expression. The change (medium versus TNF-α 10 ng/ml and medium versus TNF-α 100 ng/ml) in IL6 mRNA transcription was positively associated with the change in PRB, but not PRA with both DNG and NETA treatment. The change in IL8 mRNA was negatively associated with AR expression in the presence of NETA. The change in MCP-1 mRNA expression was positively associated with GR expression and negatively associated with MCR after MPA treatment. The associations between the change in cytokines mRNA expression and nuclear receptors protein expression in response to progestins activity may indirectly suggest different activities of these compounds at a local level worthy of further investigations.

Abstract
Sentinel lymph node (SLN) mapping in endometrial cancer (EMCA) is rapidly gaining acceptance in the clinical community. As compared to a full lymphadenectomy in every patient, to a selective lymphadenectomy after frozen section of uterus in selected patients with intrauterine risk factors or to a strategy in which a lymphadenectomy is always omitted, SLN mapping seems to be a reasonable and oncologically safe middle ground. Various protocols can be used when applying an SLN mapping. In this manuscript we review the characteristics, toxicity and clinical impact of technetium-99m radiocolloid (Tc-99m), of the blue dyes (methylene blue, isosulfan blue and patent blue) and of indocyanine green (ICG). ICG has an excellent toxicity profile, has higher overall and bilateral detection rates as compared to blue dyes and higher bilateral detection rates as compared to a combination of Tc-99m and blue dye. The detrimental effect of BMI on the detection rates is attenuated when ICG is used as a tracer. The ease of use of the ICG SLN mapping is perceived by the patients as a better quality of care delivered. Whenever possible, ICG should be favored over the other tracers for SLN mapping in EMCA patients.

Abstract
e17063 Background: OC has the highest mortality rate amongst gynecological malignancies. Nevertheless a small fraction of OC patients will survive longer than 8 years. Aim of our study was to analyze differences in the clinical appearance and management of LTS versus “classical” OC patients. Methods: OC patients living longer than 8 years were identified within the TOC Network between 1998 and 2008, representing the LTS subgroup. PSM analysis was used to select comparable groups of LTS and OC patients who died within first 5 years (control group - CG). PSM was conducted using nearest neighbor caliper matching without replacement to match LTS and CG for age, FIGO and residual tumor mass. All calculations were performed with the R project for Statistical Computing (R-packages used: “MatchIt”). Results: A total of 347 OC patients with different histological subtypes were included in the current analysis, i.e. 173 LTS and 174 in the CG. After PSM 114 patients remained in each group. Patients had similar age, FIGO stage and residual mass (p = 0.99, p = 0.35 and p = 0.88, respectively). Tumor spread in middle and upper abdomen (p = 0.002 and 0.013, respectively) was higher and diaphragm, mesentery and peritoneum (p = 0.009, 0.037 and 0.002, respectively) were significantly more often involved in CG than in the LTS. When only considering the HGSOC patients, 95 patients remained in each group. All patients received surgery and platinum based chemotherapy. The PSM analysis showed significant higher involvement of upper abdomen (p = 0.028), higher peritoneal spread (p = 0.002), higher ascites volume (p = 0.0007) and higher bowel resection rates (p = 0.002) in the CG compared to LTS. Neoadjuvant chemotherapy rate was similar in the LTS and CG (p = 0.5). Conclusions: Based on this PSM analysis, HGSOC-LTS seem to have mainly similar clinical pattern as the control group, however with lower rates of ascites and involvement of upper abdomen. Molecular characterization including analysis of clonal diversity might help elucidate mechanisms of tumor spread and good prognosis.

Abstract
Background Intestinal differentiation of primary mucinous adenocarcinoma of the uterine corpus is exceedingly rare in comparison to the approximately 25% rate in endocervical and ovarian mucinous carcinoma. Additionally, little is known about the related genetic and epigenetic alterations, even though large-scale molecular characterisation of the different types of endometrial cancer took place in the TCGA project along the entities defined by the recent WHO classification. Case presentation We present a 62-year-old patient harbouring a primary mucinous carcinoma of the uterine corpus with a morphological resemblance to mucinous colorectal adenocarcinoma. The intestinal differentiation was substantiated by CDX2 and CK20 positivity in the absence of PAX8, p16, WT1, p53, ER, PgR, AFP, SALL4 and Glypican3. A high MSI status with MLH1 hypermethylation was revealed by molecular testing. Conclusion Intestinal differentiation of mucinous adenocarcinoma of the endometrium is a unique observation. Besides morphology, it obviously can share molecular features of sporadic MSI colorectal cancers. It can be speculated that either CDX2 positive morula formation or intestinal metaplasia of the endometrium as rare conditions might be the origin of carcinogenesis for this type II endometrial cancer. Both conditions were not detectable in this case. Of note, categorising endometrial cancers in genetic subgroups like MSI high cancers alone might lead to the integration of likewise morphologically different tumours like the case presented here with intestinal differentiation. Hence, careful genotype-phenotype correlations are warranted for studies of mucinous adenocarcinoma of the endometrium.

Abstract
OBJECTIVE To determine whether written information and/or counseling based on the WOMAN-PRO II Program decreases symptom prevalence in women with vulvar neoplasia by a clinically relevant degree, and to explore the differences between the 2 interventions in symptom prevalence, symptom distress prevalence, and symptom experience. METHODS A multicenter randomized controlled parallel-group phase II trial with 2 interventions provided to patients after the initial diagnosis was performed in Austria and Switzerland. Women randomized to written information received a predefined set of leaflets concerning wound care and available healthcare services. Women allocated to counseling were additionally provided with 5 consultations by an Advanced Practice Nurse (APN) between the initial diagnosis and 6months post-surgery that focused on symptom management, utilization of healthcare services, and health-related decision-making. Symptom outcomes were simultaneously measured 5 times to the counseling time points. RESULTS A total of 49 women with vulvar neoplasia participated in the study. Symptom prevalence decreased in women with counseling by a clinically relevant degree, but not in women with written information. Sporadically, significant differences between the 2 interventions could be observed in individual items, but not in the total scales or subscales of the symptom outcomes. CONCLUSIONS The results indicate that counseling may reduce symptom prevalence in women with vulvar neoplasia by a clinically relevant extent. The observed group differences between the 2 interventions slightly favor counseling over written information. The results justify testing the benefit of counseling thoroughly in a comparative phase III trial.

Abstract
PURPOSE The aim of our study was to investigate the sonographic changes of the cervical length during pregnancy after the placement of a transvaginal cervical cerclage (TVC) or a laparoscopic abdominal cerclage (LAC) in patients with cervical insufficiency (CI). METHODS Between January 2008 and March 2015, a retrospective analysis of all women undergoing a prophylactic laparoscopic (LAC group) or transvaginal (TVC group) cerclage due to cervical insufficiency was conducted. Nonparametric variables were analysed with the Mann-Whitney (U) test, and categorical-type outcomes were analysed with the Fisher's exact test. A p value <0.05 was considered as significant. Data analysis was performed using Prism 5 for Mac OS X. RESULTS Thirty-eight patients were included. Of these, 18 and 20 underwent an LAC and a TVC, respectively. Mean gestational age at surgery in the LAC and TVC groups was 11.4 ± 1.6 and 17 ± 3 weeks, respectively (p < 0.05). The cervical length prior to surgery was similar among the two groups. After cerclage placement, the distance between the tape and the external cervical os differed significantly between the two groups (LAC: 31.5 ± 8.8 mm vs TVC: 13.5 ± 4.9 mm; p < 0.0001) (Fig. 1). During pregnancy, the cervical length in the TVC group showed a significant shortening (from 26.6 ± 7 mm before surgery to 13.2 ± 7 mm at 33 weeks; p < 0.0001), while in the LAC group, the cervical length remained unchanged. CONCLUSIONS In patients with CI, LAC is associated with a better preservation of the cervical length throughout pregnancy as compared to TVC.

Abstract
PURPOSE The aim of this study was to assess whether the intrafollicular cytokine profile in naturally developed follicles is different in women with endometriosis, possibly explaining the lower reproductive outcome in endometriosis patients. METHODS A matched case-control study was conducted at a university-based infertility and endometriosis centre. The study population included 17 patients with laparoscopically and histologically confirmed endometriosis (rAFS stages II-IV), each undergoing one natural cycle IVF (NC-IVF) treatment cycle between 2013 and 2015, and 17 age-matched NC-IVF women without diagnosed endometriosis (control group). Follicular fluid and serum was collected at the time of follicle aspiration. The concentrations of inflammatory cytokines (IL-1β, IL-6, IL-8, IL-15, IL-18, TNF-α) and hormones (testosterone, estradiol, AMH) were determined in follicular fluid and serum by single or multiplexed immunoassay and compared between both groups. RESULTS In the follicular fluid, IL-1β and IL-6 showed significantly (P < 0.001 and 0.01, respectively) higher median concentrations in the endometriosis group than in the control group and a tendency towards endometriosis severity (rAFS stage) dependence. The levels of the interleukins detectable in follicular fluid were significantly higher than those in the serum (P < 0.01). Follicular estradiol concentration was lower in severe endometriosis patients than in the control group (P = 0.036). Follicular fluid IL-1β and IL-6 levels were not correlated with estradiol in the same compartment in neither patient group. CONCLUSIONS In women with moderate and severe endometrioses, some intrafollicular inflammatory cytokines are upregulated and not correlated with intrafollicular hormone concentrations. This might be due to the inflammatory microenvironment in endometriosis women, affecting follicular function and thereby possibly contributing to the reproductive dysfunction in endometriosis.

Abstract
BACKGROUND/AIMS Laparoscopy is an established, safe, and feasible management option for tubal pregnancies, even in women with significant hemoperitoneum. In case of interstitial pregnancy, however, a laparoscopic surgical approach is still a matter of debate. The objective of this study is to evaluate the safety and feasibility of a laparoscopic approach to interstitial pregnancies. METHODS A total of 92 women with ectopic pregnancy who underwent a surgical management from April 2009 to August 2015 were reviewed. Clinical and surgical outcomes of confirmed interstitial pregnancies (n = 10) (IP group) were compared with those of "more distal" tubal pregnancies (n = 79) (TP group). RESULTS Although there were no differences between the two groups in gestational age, ß-hCG values were significantly higher in the IP group (p = 0.005). All patients with IP were treated by laparoscopic wedge resection. The rate of surgical complications (p = 0.413) and subsequent MTX treatment (p = 0.531) were not significantly different between groups. Operating room (OR) time (p = 0.007) was higher in the IP than in the TP group. After stratification for the presence of hemoperitoneum this difference remained, with patients in the IP group having longer OR time (p = 0.034) and additionally higher intra-operative blood loss (EBL) (p = 0.013). On the other hand, in the absence of hemoperitoneum no differences between the two groups were observed. CONCLUSIONS In experienced hands, the laparoscopic management of interstitial pregnancies seems to be as safe and feasible as that of other tubal pregnancies. However, it could be technically more challenging, especially in case of hemoperitoneum.

Abstract
Endometriosis is an estrogen-dependent disease characterised by the growth of endometrial epithelial and stromal cells outside the uterus creating a chronic inflammatory environment that further contributes to disease progression. The first choice treatment for endometriosis is currently progestin mediated hormone modulation. In addition to their progestogenic activity however, progestins also have the potential to bind to other nuclear receptors influencing their local activity on endometriotic cells. This local activity will be dependent on the steroid hormone receptor expression that occurs in endometrial cells in a chronic inflammatory environment. We therefore aimed to quantify receptors targeted by progestins in endometrial stromal cells after exposure to inflammation. Using primary endometrial stromal cells isolated from women with endometriosis we examined the mRNA and protein expression of the progesterone receptors A and B, membrane progesterone receptors 1 and 2, androgen receptors, mineralocorticoid receptors and glucocorticoid receptors after exposure to the inflammatory cytokines tumor necrosis factor α (TNFα) and interleukin 1β (IL-1β). The results indicate that both cytokines reduced the expression of progesterone receptors and increased the expression of the glucocorticoid receptors in the endometrial stromal cells. The change in expression of progestin targets in endometrial stromal cells in an inflammatory environment could contribute to the progesterone resistance observed in endometriotic cells and ultimately influence the design of hormonal therapies aimed at treating this disease.

Abstract
BACKGROUND Historically, blue dyes, (99)Tc or a combination of the two tracers have been used for sentinel lymph node (SLN) mapping in cervical and endometrial cancer patients. Indocyanine green (ICG), as a tracer, has been recently introduced in this setting. Our goal was to assess the differences in overall and bilateral detection rates as well as in false-negative rates among the different tracers. METHODS The electronic databases PubMed, MEDLINE, and Scopus were searched in January 2016 by searching the terms "sentinel lymph node" and "dye" and "indocyanine green," and "cervical cancer" or "endometrial cancer." Series comparing different tracers injected intracervically and reporting the detection rate and/or SLN false-negative rate were selected. RESULTS Forty-five studies were retrieved. Six studies including 538 patients met selection criteria. Compared with blue dyes, ICG SLN mapping had higher overall (odds ratio [OR] 0.27; 95 % confidence interval [CI] 0.15-0.50; p < 0.0001) and bilateral detection rates (OR 0.27; 95 % CI 0.19-0.40; p < 0.00001). No differences were found between ICG and (99)TC, although these results are based on data of a single series. No differences in overall and bilateral detection rates were found between ICG and the combination of blue dyes and (99)TC. The pooled analysis of false-negative rates data showed no difference in false-negative rates between tracers. CONCLUSIONS In cervical and endometrial cancer, ICG SLN mapping seems to be equivalent to the combination of blue dyes and (99)TC in terms of overall and bilateral detection rates. Its safety profile and ease of use may favor its employment respect to conventional tracers.

Abstract
BACKGROUND Endometriosis, the growth of endometrial tissue outside the uterine cavity, is associated with chronic pelvic pain, subfertility and an increased risk of ovarian cancer. Current treatments include the surgical removal of the lesions or the induction of a hypoestrogenic state. However, a reappearance of the lesion after surgery is common and a hypoestrogenic state is less than optimal for women of reproductive age. Additional approaches are required. Endometriosis lesions exist in a unique microenvironment characterized by increased concentrations of hormones, inflammation, oxidative stress and iron. This environment influences cell survival through the binding of membrane receptors and a subsequent cascading activation of intracellular kinases that stimulate a cellular response. Many of these kinase signalling pathways are constitutively activated in endometriosis. These pathways are being investigated as therapeutic targets in other diseases and thus may also represent a target for endometriosis treatment. METHODS To identify relevant English language studies published up to 2015 on kinase signalling pathways in endometriosis, we searched the Pubmed database using the following search terms in various combinations; 'endometriosis', 'inflammation', 'oxidative stress', 'iron', 'kinase', 'NF kappa', 'mTOR', 'MAPK' 'p38', 'JNK', 'ERK' 'estrogen' and progesterone'. Further citing references were identified using the Scopus database and finally current clinical trials were searched on the clinicaltrials.gov trial registry. RESULTS The current literature on intracellular kinases activated by the endometriotic environment can be summarized into three main pathways that could be targeted for treatments: the canonical IKKβ/NFκB pathway, the MAPK pathways (ERK1/2, p38 and JNK) and the PI3K/AKT/mTOR pathway. A number of pharmaceutical compounds that target these pathways have been successfully trialled in in vitro and animal models of endometriosis, although they have not yet proceeded to clinical trials. The current generation of kinase inhibitors carry a potential for adverse side effects. CONCLUSIONS Kinase signalling pathways represent viable targets for endometriosis treatment. At present, however, further improvements in clinical efficacy and the profile of adverse effects are required before these compounds can be useful for long-term endometriosis treatment. A better understanding of the molecular activity of these kinases, including the specific extracellular compounds that lead to their activation in endometriotic cells specifically should facilitate their improvement and could potentially lead to new, non-hormonal treatments of endometriosis.

Abstract
Background In endometrial cancer (EMCA), indocyanine green (ICG) sentinel lymph node (SLN) mapping has been reported, mainly in conjunction with robotic surgery. Objective We aimed to evaluate detection rates, sensitivity, and false negative (FN) rate of laparoscopic ICG SLN mapping in EMCA, and to evaluate differences in surgical outcomes between patients subjected to SLN biopsy only versus lymphadenectomy. Methods A retrospective analysis of EMCA patients undergoing ICG SLN mapping ± pelvic (PLND) and/or para-aortic lymphadenectomy (PALND) was performed. Detection rates were calculated for the entire cohort. Sensitivity and FN rates were calculated for patients undergoing lymphadenectomy after SLN mapping, and surgical outcome was compared among patients undergoing SLN mapping only versus lymphadenectomy. Results Of 75 patients, 33 underwent SLN mapping and 42 underwent SLN mapping followed by PLND/PALND. Overall and bilateral detection rates were 96 % (72/75) and 88 % (66/75), respectively, and the median number of removed SLNs, pelvic non-SLNs (NSLN) and para-aortic NSLNs was 3, 27, and 19, respectively. With a FN rate of 8.3 %, only one patient had bilateral FN SLNs and a metastatic para-aortal NSLN. Estimated blood loss (EBL) and operative (OR) time were significantly lower in patients undergoing SLN mapping only. No differences in complication rates between patients undergoing SLN mapping only and patients undergoing lymphadenectomy were recorded. Conclusions Laparoscopic ICG SLN mapping has excellent overall and bilateral detection rates and a low FN rate. Compared with lymphadenectomy, SLN biopsy is associated with significantly lower EBL and shorter OR time.

Abstract
Background and Purpose 99TC combined with blue-dye mapping
is considered the best sentinel lymph node (SLN) mapping technique in cervical cancer. Indocyanine green (ICG) with near infrared fluorescence imaging has been introduced as a new methodology for SLN mapping. The aim of this study was to compare these two techniques in the laparoscopic treatment of cervical cancer. Methods Medical records of patients undergoing laparoscopic SLN mapping for cervical cancer with either 99Tc and patent blue dye (Group 1) or ICG (Group 2) from April 2008 until August 2012 were reviewed. Sensitivity, specificity, and overall and bilateral detection rates were calculated and compared. Results Fifty-eight patients were included in the study—36 patients in Group 1 and 22 patients in Group 2. Median tumor diameter was 25 and 29 mm, and mean SLN count was 2.1 and 3.7, for Groups 1 and 2, respectively. Mean non-SLN (NSLN) count was 39 for both groups. SLNs were ninefold more likely to be affected by metastatic disease compared with NSLNs (p < 0.005). Sensitivity and specificity were both 100 %. Overall detection rates were 83 and 95.5 % (p = nonsignificant), and bilateral detection rates were 61 and 95.5 % (p < 0.005), for Groups 1 and 2, respectively. In 75 % of cases, SLNs were located along the external or internal iliac nodal basins. Conclusions ICG SLN mapping in cervical cancer provides high overall and bilateral detection rates that compare favorably with the current standard of care.

Abstract
The minimally invasive approach for hysterectomy with proven benefits and lower morbidity has become the gold standard, even in women with large uterine masses. Most women with a malignant condition present with abnormal vaginal bleeding and/or suspicious imaging such that few are diagnosed by final histopathology after surgery. However, if a malignancy is not diagnosed preoperatively, intraabdominal morcellation for uterus extraction has an increased risk for potential tumor spread and peritoneal metastases, especially in cases of unexpected leiomyosarcoma. We describe a simple method to wrap the uterus in a contained environment with a plastic bag through the posterior vaginal fornix prior to conventional coring morcellation for vaginal extraction in total laparoscopic hysterectomy. We further describe our experience with a risk stratification and treatment algorithm to implement this procedure in daily routine. A video and an illustrating sketch demonstrate the simplicity and safety of the procedure.

Abstract
BACKGROUND The study was designed to compare the effect of in vitro FSH stimulation on the hormone production and gene expression profile of granulosa cells (GCs) isolated from single naturally matured follicles obtained from natural cycle in vitro fertilization (NC-IVF) with granulosa cells obtained from conventional gonadotropin-stimulated IVF (c-IVF). METHODS Lutein granulosa cells from the dominant follicle were isolated and cultured in absence or presence of recombinant FSH. The cultures were run for 48 h and six days. Messenger RNA (mRNA) expressions of anti-Müllerian hormone (AMH) and FSH receptor were measured by quantitative polymerase chain reaction (qPCR). AMH protein and progesterone concentration (P4) in cultured supernatant were measured by ELISA and RIA. RESULTS Our results showed that the mRNA expression of AMH was significantly higher in GCs from NC- than from c-IVF on day 6 after treatment with FSH (1 IU/mL). The FSH stimulation increased the concentration of AMH in the culture supernatant of GCs from NC-IVF compared with cells from c-IVF. In the culture medium, the AMH level was correlated significantly and positively to progesterone concentration. CONCLUSIONS Differences in the levels of AMH and progesterone released into the medium by cultured GC as well as in AMH gene expression were observed between GCs obtained under natural and stimulated IVF protocols. The results suggest that artificial gonadotropin stimulation may have an effect on the intra-follicular metabolism. A significant positive correlation between AMH and progesterone may suggest progesterone as a factor influencing AMH secretion.
