Targeted lipids and inflammation modulators were analyzed in abdominal fluid and serum revealing an association between endocannabinoids (2-AG and AEA) and gynecological pain., Endocannabinoid (eCB) levels fluctuate in inflammatory conditions and as such may take part in endometriosis-associated pain or even in endometriosis pathogenesis. In this case–control (23 cases and 19 controls) study, targeted lipids were measured in the serum and peritoneal fluid collected during laparoscopy. Endometriosis was confirmed histologically. Dysmenorrhea, abdominal pain, and dyspareunia were assessed using the Numeric Rating Scale for pain. Steroids, eCBs, and related lipids were quantified by liquid chromatography-tandem mass spectrometry (LC-MS/MS). Tumor necrosis factor alpha, IL-8, PAPP-A, PP14, RANTES, OPG, MIDKINE, MCP-1, VEGF, leptin, and defensins were quantified by ELISA. We found that eCB levels were significantly influenced by both noncyclic and cyclic abdominal pain. Specifically, women suffering from noncyclic abdominal pain were characterized by a higher 2-AG level in the peritoneal fluid throughout the menstrual cycle, whereas women suffering from dysmenorrhea had higher 2-AG levels and lower AEA levels during the proliferative phase alone. In addition, 2-AG positively correlated with prostaglandin E2 (PGE2), and the ratio AEA/2-AG positively correlated with defensins, suggesting a possible link between endocannabinoids system and inflammatory pain. The results of the current study indicate that the eCB system may play a role in endometriosis-associated pain, but additional studies are needed to investigate the causal relationship.

Objectives Genetic testing rates for hereditary breast and ovarian cancer (HBOC) have steadily increased during the past decades resulting in a growing population of young and healthy mutation carriers. Available data on fertility issues in BRCA mutation carriers is rising but the results remain to some extent still conflicting. We have performed a systematic literature review in order to get an overview concerning the current evidence on fertility issues in BRCA mutation carriers. Data were analyzed critically with the aim to deliver physicians a solid basis for (onco) fertility counseling in women with BRCA mutations. Content We present the latest data on cancer risks in women with HBOC and analyze the influence of cancer treatment and preventive surgery on the reproductive potential. Epidemiological studies on fertility issues in BRCA mutation carriers showed heterogeneous results. However, several authors showed a decreased ovarian reserve with lower Anti-Müllerien hormone (AMH) levels and poorer response to ovarian stimulation in BRCA positive women. The diagnosis of BRCA mutations influences reproductive decision-making. Additionally, the shortened reproductive window and the need to complete family planning early has a significant psychological impact. Summary and Outlook This article highlights the importance of fertility counseling in BRCA mutation carriers. Individual fertility counseling is mandatory. Fertility preservation strategies should be discussed.

INTRODUCTION Endometriosis is a common health problem, affecting 10% of women of reproductive age. Laparoscopic surgery is proven to relieve pain and to improve fertility in women with endometriosis. However, identifying peritoneal endometriosis lesions may be difficult due to their polymorphic aspects. Endometriosis lesions harbor a high degree of neovascularization. The visualization of tissue perfusion by the additional use of near infrared fluorescence imaging with indocyanine green (ICG) may improve the detection of endometriosis lesions. MATERIAL AND METHODS In a single-center, prospective, single-arm pilot study, patients undergoing laparoscopic surgery for suspected endometriosis and/or infertility were recruited. All patients first had white light imaging with systematical documentation of all suspicious areas. ICG was then administered intravenously at .3 mg/kg bodyweight and the near infrared imaging was activated and an identical documentation of suspected lesions was performed again. After removal, the specimen were sent to pathology. CLINICAL TRIAL REGISTRATION clinicaltrials.gov NCT03850158. RESULTS In total, 173 suspected lesions were identified and excised, of which 150 had histologically proven endometriosis. Of the total number, 166 suspected lesions were detected using white-light and 32 with ICG. Among the 32 suspected lesions found with ICG, 22 were confirmed to be endometriosis. Seven additional lesions were identified with ICG alone, of which only one was histologically proven endometriosis. Positive predictive values were 89.8%, 68.8% and 86.7% for white-light laparoscopy alone, near-infrared (NIR)-ICG visualization alone, and the combination of white-light and NIR-ICG, respectively. ICG exposure time, previous abdominal surgery and rARSM stage showed a statistically significant impact on the ICG detection rate. In seven patients, ICG was used for the resection of deep infiltrating nodules from the rectum. In these cases, NIR fluorescence imaging with ICG was useful to define the borders between an endometriotic nodule and healthy tissue. CONCLUSIONS The diagnostic value of NIR-ICG imaging in identifying endometriosis appears to be minimal. ICG exposure time over 20 minutes, no previous abdominal surgery and low rASRM stages have a significant positive effect on the ICG detection rate. NIR fluorescence imaging with ICG was helpful in the resection of deep infiltrating nodules in providing a better visualization of endometriosis.

OBJECTIVES The aim of this study was to evaluate the significance of a new imaging sign, the "cloverleaf sign," in diagnosing deep infiltrating endometriosis (DIE) with magnetic resonance imaging (MRI) in concordance to intraoperative findings. MATERIALS AND METHODS This retrospective study included 103 patients operated during the January 2016 to June 2018 period with preoperative 1.5 T and 3 T MRI, with or without vaginal and rectal gel filling. Magnetic resonance imaging scans were read blinded to intraoperative findings by a specialized gynecologic radiologist and a junior radiologist, and then compared with intraoperative findings by looking at the operation report, postoperative diagnosis, and intraoperative images and videos by an experienced gynecologist surgeon specialized in endometriosis surgery. All endometriosis lesions were confirmed by pathology. The "cloverleaf sign" was defined as a cloverleaf-like figure in imaging morphology; the "leaves" formed by at least 3 different organs come together in the center of the figure formed by constrictive adhesions including T2-weighted (T2W) hypointense DIE. Operation times, intraoperative blood loss, and the frequency of DIE and bowel resections were analyzed in cloverleaf and noncloverleaf groups. The 2-sample Wilcoxon rank-sum (Mann-Whitney U) test and multivariate analysis of variance were used to calculate the significance of an overall impact of cloverleaf sign on operation time, blood loss, and the amount of the bowel resection rate. P < 0.05 was considered statistically significant. RESULTS The prevalence of DIE in the study population was 79.6%. A total of 11.5% of the patients had no endometriosis, 32.6% had rASRM I and II, and 55.9% had rASRM III and IV. Forty-six patients (45%) had received rectal and vaginal gel opacification before scanning, 57 (55%) did not. A cloverleaf sign on MRI was detected in 34 patients (15 in gel filling and 19 in nonfilling group). The interreader agreement was almost perfect 0.91 (κ). The median operation time in the cloverleaf group was 248 minutes (interquartile range [IQR], 165-330) compared with 145 minutes in the noncloverleaf group (IQR, 90-210), that is, significantly higher (P < 0.001). Intraoperative blood loss was also significantly higher in the conglomerate group (125 vs 50 mL; IQR, 100-300 vs 50-100; P < 0.001). Of the bowel resections in our study population, 41% (14/34) were performed on patients with a cloverleaf sign in the MRI, compared with 13% (9/69) in patients without the cloverleaf sign. CONCLUSIONS The "cloverleaf" MRI sign was associated with significantly longer operation time, increased intraoperative blood loss, and higher rates of bowel resection in DIE patients.

Introduction/Background* In 2021, a joint ESGO/ESTRO/ESP committee updated their evidence-based guidelines for endometrial cancer, recommending a new risk grouping incorporating both clinicopathologic and molecular parameters. We applied the new risk grouping and compared the results to those of the prior 2016 clinicopathologic system. Methodology We classified molecularly a cohort of 604 women diagnosed with endometrial cancer using immunohistochemistry for TP53 and MMR proteins on a tissue microarray, as well as Sanger sequencing for POLE mutations. These results, combined with clinicopathologic data, allowed the patients to be risk grouped using both the new 2021 molecular/clinicopathologic parameters and the prior 2016 clinicopathologic system. Result(s)* The application of the 2021 molecular markers shows Kaplan-Meier curves with a significant difference between the groups for all survival. Molecular classification under the 2021 guidelines revealed a total of 39 patients (39/594, 7%) with a change in risk group in relation to the 2016 classification system: the shift was alone due to either P53abn or POLEmut molecular marker. In order to ensure correct 2021 molecular risk classification, not all patients with endometrial cancer need a molecular diagnostic: 433 (72.9%) cases would need to be analyzed by TP53 IHC, only 46 (7.7%) by MMR IHC and 286 (48.1%) POLE sequencing reactions. Conclusion* Application of the 2021 molecular risk groups is feasible and shows significant differences in survival. IHC for TP53 and MMR and applying POLE sequencing is only needed in selected cases and leads to shifting risk groups both upward and downward for a sizeable number of patients. It is possible to significantly reduce the number of analyses required to implement the classification if resources are limited.

Women diagnosed with early-stage (FIGO 1) endometrial cancer, grade 1 and 2 can have a good prognosis. Most of these women can be treated successfully with a hysterectomy and bilateral salpingo-oophorectomy and without the additional adjuvant treatment that is accompanied by more risks for complications. However, when recurrence does occur, the consequences can be dire. Accurate decisions must therefore be made by surgeons to avoid either under- or over-treatment. Risk and patient stratification for tailoring treatment still need further improvement. Both histopathology and genetic variants could be integrated into the decision process if relevant factors were identified. Morphological features and the presence of selected genetic mutations in isolated malignant endometrial epithelial cells from these tumors were analyzed in a strictly defined cohort of FIGO 1, grade 1 and 2 low-risk endometrial cancer. Their presence in this cohort, their relation to recurrence, and the association between histopathological features and mutations were determined. This analysis was performed using archival formalin-fixed paraffin-embedded tissue, complete re-evaluation of histopathological features, laser capture microdissection of epithelial cells, and a polymerase chain reaction-based mutational screening assay. Twenty-one women with recurrence, after initial identification as low-risk endometrial cancer, were compared with 20 matched control women. The histological marker of lymphovascular invasion was significantly associated with recurrence. There was also a very high prevalence of mutations in CTNNB1 gene, occurring in 50% of this cohort. PTEN mutations were also observed in 27.8% of cases and PIK3CA mutations in 22.2%; none of these mutations were significantly related to recurrence. This study supports the importance of lymphovascular space invasion to identify women with significant risk for recurrence in initially low-risk, early-stage endometrial cancer. It also identifies CTNNB1 as a significant mutation in early-stage disease, and although it may not represent a marker for recurrence its high prevalence in early stage disease could have relevance for both pathogenesis and early treatment.

Ovarian cancer is the most lethal gynecological cancer. Numerous subtypes exist, each with distinct risk factors and prognosis. What underlies these subtypes and their progression is not clear, although inflammation through NFκB may play a key role. We performed a study on a series of well-characterized in vitro ovarian cancer models including TOV21G, TOV112D and OV90 originally derived from clear cell, endometrioid and high grade serous carcinoma respectively. Cells were treated with 0–100 ng/ml TNFα over 6–72 h. The NFκB pathway was inhibited by a series of NFκB pathway inhibitors, 100μM PDTC, 1μM PS-1145 and 200nM TPCA and the influence on cellular viability and inflammation was measured via an MTS assay and qPCR respectively. TNFα stimulation of NFκB was confirmed via Western blot. We found TNFα facilitated continued growth of TOV21G and TOV112D cells in an NFκB independent method. In contrast, TNFα inhibited OV90 cell growth in an NFκB dependent manner. TNFα stimulated production of IL-6, IL-8, MCP-1 and RANTES on all three cells lines, but only IL-6 and IL-8 were via NFκB mediated mechanisms. These results indicate TNFα may have diverse effects mediated through both NFκB and non-NFκB pathways on ovarian cancer cells. Understanding the role for TNFα in each subtype may have significant implications for charting disease progression and designing personalized treatments., Serous, Clear cell, Endometrioid, Ovarian cancer, Inflammation, TNFα, Epithelial

BackgroundThis study aimed to evaluate the clinical value of indocyanine green sentinel lymph node (SLN) mapping in patients with vulvar cancer. The conventional procedure of SLN mapping in vulvar cancer includes peritumoral injection of technetium-99m nanocolloid before surgery and intraoperative injection of a blue dye. However, these techniques harbor some limitations. Near-infrared fluorescence imaging with indocyanine green has gained popularity in SLN mapping in different types of cancer.MethodsWe analyzed retrospectively vulvar cancer patients at our institution between 2013 and 2020 undergoing indocyanine green SLN mapping by applying video telescope operating microscope system technology.Results64 groins of 34 patients were analyzed. In 53 groins we used technetium-99m nanocolloid, in four patent blue, and in five both techniques, additionally to indocyanine green for SLN detection. In total, 120 SLNs were identified and removed. The SLN detection rate of indocyanine green was comparable to technetium-99m nanocolloid (p=.143) and higher than patent blue (p=.003). The best results were achieved using a combination of ICG and technetium-99m nanocolloid (detection rate of 96.9%). SLN detection rates of indocyanine green were significantly higher in patients with positive lymph nodes (p=.035) and lymphatic space invasion (p=.004) compared to technetium-99m nanocolloid.ConclusionIndocyanine green SLN mapping in vulvar cancer is feasible and safe, with reasonable detection rates. Due to its easy application and few side effects, it offers a sound alternative to the conventional SLN mapping techniques in vulvar cancer. In patients with lymph node metastasis, indocyanine green even outperformed technetium-99m nanocolloid in terms of detection rate.

(1) Background: The aim of this study was to evaluate the impact of endometriosis on postoperative pain following laparoscopic hysterectomy, (2) Methods: A total of 214 women who underwent a laparoscopic hysterectomy between January 2013 and October 2017 were divided into four subgroups as follows: (1) endometriosis with chronic pain before the surgery (n = 57), (2) pain-free endometriosis (n = 50), (3) pain before the surgery without endometriosis (n = 40), (4) absence of both preoperative pain and endometriosis (n = 67). Postoperative pain was compared by using Visual Analog Scale (VAS) scores and by tracking the use of painkillers during the day of surgery and the first two postoperative days, (3) Results: Women with chronic pain before the surgery reported higher VAS scores during the first postoperative days, while the use of analgesics was similar across the groups. There was no difference in the postoperative pain when comparing endometriosis patients to non-endometriosis patients, (4) Conclusions: Women with chronic pelvic pain demonstrated increased postoperative pain after laparoscopic hysterectomy, which was independent of the presence or severity of endometriosis. The increased VAS scores did not, however, translate into equally greater use of painkillers, possibly due to the standardised protocols of analgesia in the immediate postoperative period. These findings support the need for careful postsurgical pain management in patients with pain identified as an indication for hysterectomy, independent of the extent of the surgery or underlying diagnosis.

Introduction/Background The role of lymphadenectomy in surgical staging for endometrial cancer remains controversial. The standard of care – consisting of a pelvic and para-aortic lymphadenectomy (LND) – has failed to show survival advantage while leading to an increased peri- and postoperative morbidity. Sentinel lymph node (SLN) mapping has gained popularity, offering a compromise between no nodal staging and complete LND. Multiple studies have demonstrated high detecection rates and negative predictive values of SLN mapping with near-infrared fluorescence imaging and indocyanine green (ICG) in endometrial cancer. However, the literature contains limited data on its safety and oncological outcomes. Aim of this study is to evaluate the oncological outcome of SLN mapping in patients with intermediate-risk endometrial cancer. Methodology In a retrospective, single-center study, we investigated the oncological outcome of patients with stage I intermediate-risk endometrial cancer who underwent surgical staging at our institution between February 2013 and July 2020. Results Out of a total number of 306 patients with endometrial cancer, 57 patients were diagnosed with node-negative intermediate-risk endometroid endometrial cancer (FIGO IA grade 3, FIGO IB grade 1 or 2). All patients were treated with laparoscopic hysterectomy and bilateral salpingo-oophorectomy with ICG SLN mapping. 31 patients additionally underwent comprehensive surgical staging (four systematic pelvic lymphadenectomies and 27 pelvic and para-aortic lymphadenectomies, LND group). Mean follow up time was 38.0 months. Adjuvant treatment consisted of vaginal brachytherapy in 49 patients, additional chemotherapy in four patients and no adjuvant treatment in eight patients. Between the two cohorts, there were no differences in age or BMI. The mean number of lymph nodes removed (4.04 vs. 45.5), the duration of the surgical procedure (131.3 vs. 287 minutes) as well as the intraoperative blood loss (101.9 vs. 258.1 ml) were significantly higher in the LND group (p=0.000, 0.000 and 0.026, respectively). Recurrence rates (7.7% SLN, 9.7% LND, p=0.585) and death due to disease (3.8% SLN, 3.2% LND, p=0.709) were similar between the two groups. Further on, there was no statistically significant difference in overall and recurrence free survival for patients with SLN mapping only compared to the LND cohort (p=0.541 and 0.480, respectively). Conclusion In our cohort, the use of ICG SLN mapping alone did not impair oncological outcome compared to a complete lymphadenectomy. It therefore might provide an efficient alternative of nodal staging with less morbidity in intermediate-risk endometrial cancer patients. However, prospective studies on larger numbers of patients are needed to confirm our findings. Disclosures No disclosures.

Objective To evaluate the ability of demographic and sonographic variables and the Proactive Molecular Risk Classifier for Endometrial cancer (ProMisE) classification to predict preoperatively tumor recurrence or progression in women with endometrial cancer. Methods The study included 339 women with histologically confirmed endometrial cancer who underwent expert transvaginal ultrasound in a single center before surgery as part of the prospective International Endometrial Tumor Analysis 4 study or who were evaluated using the same protocol. The tumors were classified according to histotype, FIGO (International Federation of Gynecology and Obstetrics) grade and FIGO stage. In addition, molecular analysis was performed for classification into the four ProMisE subtypes: polymerase‐ϵ exonuclease domain mutations (POLE EDM), mismatch repair proteins deficiency (MMR‐D), protein 53 wild type (p53 wt) and protein 53 abnormal (p53 abn). Demographic and preoperative sonographic characteristics, tumor recurrence or progression and survival were compared between the ProMisE subgroups. Cox regression analysis was used to identify prognostic factors associated with recurrence or progression, using univariable models to study crude associations and multivariable models to study adjusted associations. Logistic regression and receiver‐operating‐characteristics (ROC)‐curve analysis were used to assess the predictive ability of the preoperative prognostic factors regarding recurrence or progression of cancer within 3 years after surgery, and to compare their predictive ability to that of the European Society for Medical Oncology (ESMO) preoperative (based on depth of myometrial invasion, histotype and grade) and postoperative (based on histotype, grade, surgical stage and lymphovascular space invasion) risk classifications. In a separate subanalysis, cases were stratified according to ProMisE p53 abn status (present vs absent) and sonographic tumor size (anteroposterior (AP) diameter

STUDY OBJECTIVE To evaluate the prognostic value of pre- and perioperative factors for voiding dysfunction after surgery for deep infiltrating endometriosis (DIE). DESIGN Single-center retrospective cohort study. SETTING University hospital. PATIENTS A total of 198 women with DIE in the posterior compartment who underwent surgery and a postoperative bladder scan. INTERVENTIONS Surgical resection of the DIE nodule from the dorsal compartment. MEASUREMENTS AND MAIN RESULTS After surgery, 41% of the patients initially experienced voiding dysfunction (defined as >100 mL postvoid residual urine volume at second bladder scan). The number decreased to 11% by the time of hospital discharge. Among those with a need for self-catheterization after discharge (n���=���17), voiding dysfunction lasted for a median of 41 days before a return to normal bladder function, with a residual urine volume of 3 cm in lateral distension. Receiver operating characteristic curve analyses showed that a first residual urine volume >220 mL has a good predictive value for the risk of intermittent self-catheterization (area under the receiver operating characteristic curve 0.893; p 3 cm, a higher risk of postoperative voiding dysfunction is to be expected.

An 81-year-old patient developed an exulcerous tumor in her left breast 21 years after breast cancer treatment with lumpectomy and adjuvant radiotherapy. At the time of the initial treatment 21 years ago, whole breast irradiation was performed with a prescribed dose of 48 Gy and a maximal dose of 69 Gy. In addition, the patient received a 14.7 Gy boost with multicatheter brachytherapy as partial breast irradiation. In general, fat necrosis after radiotherapy, surgery or trauma is a minor problem for patients, but can lead to diagnostic difficulties. The incidence varies: the literature indicates that it occurs in up to 34% of cases. The direct pathogenesis is not clear; it can be due to high radiation dose to the breast, dosimetric inhomogeneities or surgical complications (seromas and inflammation). The tumor in the case described here, occurring more than two decades after the primary treatment, is a rarity in this extent and is an unusual clinical, radiological, and histological finding. It provides a good example of the need for an individualized approach to treatment.

BACKGROUND Curative management of deep infiltrating endometriosis requires complete removal of all endometriotic implants. Surgical approach to rectal involvement has become a topic of debate given potential postoperative bowel dysfunction and complications. OBJECTIVE This study aims to assess long-term postoperative evacuation and incontinence outcomes after laparoscopic segmental rectal resection for deep infiltrating endometriosis involving the rectal wall. DESIGN This is a retrospective study of prospectively collected data. SETTINGS This single-center study was conducted at the University Hospital of Bern, Switzerland. PATIENTS Patients with deep infiltrating endometriosis involving the rectum undergoing rectal resection from June 2002 to May 2011 with at least 24 months follow-up were included. MAIN OUTCOME MEASURES Aside from endometriosis-related symptoms, detailed symptoms on evacuation (points: 0 (best) to 21 (worst)) and incontinence (0-24) were evaluated by using a standardized questionnaire before and at least 24 months after surgery. RESULTS Of 66 women who underwent rectal resection, 51 were available for analyses with a median follow-up period of 86 months (range: 26-168). Forty-eight patients (94%) underwent laparoscopic resection (4% converted, 2% primary open), with end-to-end anastomosis in 41 patients (82%). Two patients (4%) had an anastomotic insufficiency; 1 case was complicated by rectovaginal fistula. Dysmenorrhea, nonmenstrual pain, and dyspareunia substantially improved (p < 0.001 for all comparisons). Overall evacuation score increased from a median of 0 (range: 0-11) to 2 points (0-15), p = 0.002. Overall incontinence also increased from 0 (range: 0-9) to 2 points (0-9), p = 0.003. LIMITATIONS This study was limited by its retrospective nature and moderate number of patients. CONCLUSIONS Laparoscopic segmental rectal resection for the treatment of deep infiltrating endometriosis including the rectal wall is associated with good results in endometriotic-related symptoms, although patients should be informed about possible postoperative impairments in evacuation and incontinence. However, its clinical impact does not outweigh the benefit that can be achieved through this approach. See Video Abstract at http://links.lww.com/DCR/A547.

Introduction/Background The conventional procedure of sentinel lymph node (SLN) mapping in vulvar cancer includes peritumoral injection of technetium-99m radiocolloid (Tc-99m) the day before surgery and intraoperative injection of methylene blue. However, these techniques have some weaknesses. Near infrared (NIR) fluorescence imaging with indocyanine green (ICG) has recently gained popularity in SLN mapping in different types of cancer. The aim of this study is to evaluate the clinical value of ICG SLN mapping in patients with vulvar cancer. Methodology We retrospectively analyzed all patients at our institution with vulvar cancer undergoing SLN mapping using NIR fluorenscence imaging with ICG by applying video telescope operating microscope (VITOM) system technology between April 2013 and May 2019. Results 55 groins of 28 patients were analyzed. In 44 groins we used Tc-99m, in four methylene blue and in five both techniques additionally to ICG for SLN detection. ICG was injected peritumorally directly before surgery and no complications due to its administration occurred. 104 SLNs were identified and removed. SLN detection rates were 87.3%, 87.8%, 77.8% and 96.4% for ICG, Tc-99m, methylene blue and the combination of ICG plus Tc-99m, respectively. SLN detection rates of ICG were significantly higher in patients with positive lymph nodes and lymphatic space invasion compared to Tc-99m (p-value 0.035 and 0.005, respectively). We further observed a higher detection rate of ICG in obese patients (94.4% vs. 87.5%); however this observation is non significant (p-value 0.69). Conclusion Accurate SLN mapping is a crucial part of vulvar cancer staging and enables avoiding unnecessary inguinofemoral lymphadenectomies. SLN mapping with ICG in vulvar cancer is feasible and safe with a detection rate comparable to Tc-99m, particularly in patients with positive lymph nodes, lymphatic space invasion or obesity. Furthermore, it is easier to perform than mapping with Tc-99m and has less side effects compared to methylene blue. Disclosure Nothing to disclose.

Background Clinical practices and testing strategies in patients with ovarian cancer differ worldwide. We therefor wanted to give an overview over the current data to advise best clinical practice. Materials and methods A systematic review of the literature was performed with the aim to define which ovarian cancer patients to refer for genetic counseling and how to perform genetic testing. We also discuss the timing of genetic testing and clinical relevance of the BRCA mutation status. Results The germline mutation rate in patients with ovarian cancer is high, independent of family history, age at diagnosis and histology. BRCA mutation carriers with ovarian cancer have improved survival rates. In recurrent ovarian cancer treatment by poly ADP ribose polymerase (PARP) inhibitors improves the disease-free survival in patients with BRCA mutations or homologous recombination deficiency with hazard ratios up to 0.23. But also patients with BRCA wild type show a benefit. The recently published SOLO-1 trial demonstrated a significant benefit for patients with germline BRCA mutations in the first line setting. By tumor testing about 7% additional BRCA mutations can be found but the somatic testing and interpretation of the results remains a challenge. Despite the clinical impact, analysis of our own data and also international publications show insufficient referral rates for genetic counseling. Conclusions Genetic testing in ovarian cancer has a prognostic and predictive value. Referral rates must be improved.

Background Breast cancer is a leading cause of cancer-related death in women worldwide. Despite extensive studies in all areas of basic, clinical and applied research, accurate prognosis remains elusive, thus leading to overtreatment of many patients. Diagnosis could be improved by introducing multigene molecular scores in standard clinical practice. Several tests that work with formalin-fixed tissue have become routine. Molecular scores usually include several genes representing processes, response to oestrogens, progestogens and human epidermal growth factor receptor 2 (Her2), respectively, which are combined additively in single values. These multi-gene scores have the advantage of being more robust and reproducible than single-gene scores. Their utility may be further enhanced by combining them with classical diagnostic parameters. Here, we present an exploratory study comparing the RISK and research versions of Oncotype DX recurrence score (RS), Prosigna Risk of Recurrence (ROR) and EndoPredict (EP) with respect to their prognostic potential for ipsilateral recurrence and/or distant relapse in brain, and we compared the scores to the intrinsic subtypes based on PAM50. Methods RNA was extracted from formalin-fixed, paraffin-embedded (FFPE) tissue cores of primary tumours, local recurrences and brain metastases. Gene expression was measured on a NanoString nCounter Analysis System. Intrinsic subtypes and molecular scores were computed according to published literature and RISK, RS, ROR and EP were compared against each other and to the intrinsic subtypes Luminal A (lumA), Luminal B (lumB), Her2-enriched (Her2↑), Basal-like (basal), and Normal-like (normal) of PAM50. Local recurrences and brain metastases were compared to their corresponding primary tumours. Results All four molecular scores were highly correlated. Highest correlations were observed among genes related to proliferation while lower correlations were found among oestrogen-related genes. The scores were significantly higher in primary tumours progressing to brain metastases as compared to recurrence-free primary tumours and primary tumours that relapsed as local recurrences. Conclusions RISK and ROR-P are prognostic for primary tumours metastasizing to the brain. All four scores, RISK, RS, EP and ROR-P failed to discriminate between primary tumours that remained recurrence-free and primary tumours relapsing as local recurrences.

Background and Purpose: In endometrial cancer, staging is performed surgically. Controversy about the required extent of lymph node removal is ongoing. In low-risk endometrial cancer (FIGO Stage 1, endometrioid histology, Grades 1 and 2), the risk of lymph-node involvement is 4–17%. Since the introduction of near-infrared optics and the use of indocyanine green, the role of sentinel lymph node removal is increasing and could offer an appropriate balance between the morbidity of a complete lymph-node dissection and the risk of missing lymph-node involvement. Methods In this retrospective comparative study on low-risk endometrial cancer, the extent of surgical lymph-node assessment (no lymphadenectomy vs removal vs lymphadenectomy) in two European institutions was compared and analyzed on the basis of perioperative data and oncological outcome. Results The study included 279 patients from: 103 (36.9%) had no lymphadenectomy, 118 (42.3%) underwent SLN removal and 58 (20.8%) underwent pelvic and/or para-aortic lymphadenectomy. There were significant differences among the groups in blood loss (p = 0.000), operation time (p = 0.000), and severity of postoperative complications (p = 0.063). In comparing only sentinel lymph-node removal vs no lymphadenectomy, there were no significant differences. No significant difference was seen between the extent of lymphadenectomy removal and the risk of recurrence. Age and Lymphovascular space invasion positivity were significant risk factors for recurrence (p = 0.004 and p = 0.019). Conclusions In early-stage, endometrial cancer, Grade 1 and 2, sentinel lymph node removal offers a convincing balance between oncological safety and perioperative morbidity. Especially in LVSI-positive cases, lymph-node evaluation in any form is crucial.

PURPOSE The aim of this study was to compare technetium radiocolloid (Tc99(m)) + blue dye (BD) versus Indocyanine green (ICG) fluorescent dye in terms of the overall detection rate and bilateral sentinel lymph node (SLN) mapping in patients with endometrial carcinoma. METHODS Patients from five European centers with apparently confined clinical stage I endometrial cancer were reviewed. A comparison was made between women who received SLN mapping with pelvic and/or aortic lymphadenectomy (LND), and women who underwent SLN algorithm (SA), was also performed between the two groups. RESULTS Three hundred and forty-two (342) women were involved (147 in the Tc99(m) + BD group and 195 in the ICG group). The overall detection rate of SLN biopsy was 97.3% (143/147) for women in the Tc99(m) + BD group and 96.9% (189/195) for women in the ICG group (p = 0.547). The bilateral mapping rate for ICG was 84.1%-significantly higher with respect to the 73.5% obtained with Tc99(m) + BD (p = 0.007). No differences in overall sensitivity (OS) and overall false negative rate (FNR) were seen between LND and SA (p value = 0.311), whereas the negative predictive value (NPV) was in favor of SA group (p value = 0.030). CONCLUSIONS In this study, fluorescent mapping using ICG resulted equivalent to the standard combined radiocolloid and BD, but real-time SLN mapping achieves a higher bilateral detection rate. The added value that this fast emerging technology promises to give certainly warrants future studies to further consolidate the advantages there are over the standard technique.

PURPOSE The adoption of a sentinel lymph node (SLN) algorithm and the presence of high bilateral detection rates have been associated with increased accuracy of SLN mapping in cervical and endometrial cancer patients. In this context, the significance of the number of SLNs removed has not yet been investigated. The aim of this study was to evaluate (a) whether or not a higher SLN removal count is associated with a reduced false-negative rate and (b) which clinical factors correlate with the number of SLNs removed. METHODS Patients with cervical or endometrial cancer who underwent SLN mapping with bilateral SLN detection followed by lymphadenectomy were evaluated retrospectively. On the basis of the mean number of the SLNs removed, the patients were divided in two groups: Group 1 included patients with up to 3 SLNs removed and Group 2 included patients with more than 3 SLNs removed. Factors predicting a higher SLN count were evaluated using univariate and multivariate analysis. RESULTS Eighty-four patients met the inclusion criteria. The two groups consisted of 42 patients each and differed only by the median SLN count. Two endometrial cancer patients in Group 1 had false-negative pelvic SLNs and isolated para-aortic metastases; no false-negative SLNs were recorded in Group 2 (p = n.s.). The results of multivariate analysis indicted that the number of SLNs removed was influenced only in cases where the operating surgeon had performed more than 20 laparoscopic ICG SLN mappings. CONCLUSIONS A higher SLN count does not seem to increase the accuracy of SLN mapping in cervical and endometrial cancer patients.

We present cases of 2 pregnant patients with early-stage cervical cancer who have undergone indocyanine green (ICG) sentinel lymph node (SLN) mapping followed by laparoscopic SLN biopsy, pelvic lymphadenectomy, and cervical conization. Eight milliliters of ICG were injected in the 4 quadrants of the cervix after having obtained an adequate pneumoperitoneum and having inspected the abdominal cavity. SLNs were identified in both hemipelvises in both patients. In the final pathologic analysis, both SLNs and non-SLNs were negative for metastatic disease. No adverse events from ICG injection were recorded. ICG SLN mapping seems to be feasible in pregnant cervical cancer patients.

Study Objective To present an unusual consequence of laparoscopic treatment of diaphragmatic endometriosis, to discuss the possible etiologies, and to propose proper management. Design A step-by-step explanation of 2 surgeries of the same patient using intraoperative video sequences (Canadian Task Force classification III). Setting University hospital. Patient A 32-year-old woman. Interventions Two Laparoscopic surgeries. Measurements and Main Results Endometriosis is estimated to affect 11% of the population 1 , 2 , with an estimated 12% of these patients having extrapelvic endometriosis [3] . When the diaphragm is involved, the disease potentially causes severe and debilitating symptoms such as catamenial chest or shoulder pain. Serious complications may involve pneumothorax and hemopneumothorax 4 , 5 , 6 . Diaphragmatic endometriosis is more common than realized and has been shown to occur simultaneously in 50% to 80% of cases with pelvic endometriosis 7 , 8 . A 32-year-old woman was admitted to our hospital with severe disabling dysmenorrhea and right shoulder pain. Despite progestin, nonsteroidal anti-inflammatory drug, and opioid treatment, pain relief remained inadequate. A laparoscopy was performed revealing diaphragmatic endometriosis, which was completely excised. A revision was necessary 14 months later because of pain recurrence in the right hemithorax and suspicion of new or persistent endometriotic lesions. The laparoscopy revealed small diaphragm fenestrations that were closed after exclusion of recurrent diaphragmatic or pleural endometriosis. No chest tube was placed, and the postoperative course was uneventful. Hormonal suppressive treatment was continued. Since the operation the patient has been pain free. Institutional Review Board/Ethics Committee ruled that approval was not required for this study (Req-2017-00415). Conclusion The diaphragm fenestrations were possibly the result of tissue necrosis caused by thermocoagulation after excision of deep endometriotic lesions during the first surgery. Using a CO 2 laser for the vaporization of superficial lesions is favorable because of the smaller depth of penetration compared with electrocautery and better access to hard to reach areas 9 , 10 . Endometriotic lesions involving the entire thickness of the diaphragm should be completely excised and the defect repaired with either sutures or staples 11 , 12 , 13 .

STUDY OBJECTIVE To show a new technique of using single-incision laparoscopic surgery (SILS) equipment in vaginal surgery to create a "pneumovagina." DESIGN Explanatory video demonstrating the technique and intraoperative findings. SETTING University hospital. PATIENT The 68-year-old patient was referred with a vaginal mesh erosion that resulted in abscess formation at the vaginal apex. The patient was symptomatic with an increasingly foul-smelling vaginal discharge for about 1 year. She had a laparoscopic sacrocolpopexy in a remote hospital 22 months before the current operation and had a total abdominal hysterectomy 15 years ago. The, patient's history was uneventful without dyspareunia, incontinence or voiding difficulties, and she was otherwise content with the sacrocolpopexy result. The local institutional review board granted exemption for this publication. INTERVENTION Frequently, pelvic organ prolapse can only be effectively treated if the surgical procedure comprises support of the central compartment. Laparoscopic sacrocolpopexy shows superior outcomes for this indication, with success rates of up to 96%. However, a rare side effect of laparoscopic sacrocolpopexy is mesh erosion, occurring in up to 2.4% [1]. These erosions are usually treated laparoscopically [2]. In this video we show an alternative route for excision of a symptomatic exposed mesh by using a transvaginal approach: The SILS trocar is used vaginally for abscess irrigation and mesh excision with minimally invasive instruments. MEASUREMENTS AND MAIN RESULTS For treatment of the abscess and removal of the exposed mesh, the SILS trocar was placed vaginally, and laparoscopic instruments were used. The abscess was incised, cleansed and irrigated, debrided, and the mesh excised. Because no mesh material was exposed after excision, the vagina was not closed to avoid creating a cavity with the risk of promoting reabscess formation, and secondary wound healing was anticipated. Laparoscopy was used to confirm that no intra-abdominal lesion coexisted or occurred. There were no signs of further infection of the residual mesh beyond the area exposed in the vagina. The patient's only symptom was foul-smelling discharge, but no back pain or signs of systemic inflammation were found. Knowing that foreign body (mesh) infection usually needs to be treated by complete mesh removal, we did not have any clues of distant mesh infection and counseled the patient that if reinfection occurred a second surgery might be necessary. Nevertheless, we treated this patient with abscess drainage and removal of large parts of the mesh. Thus, the operation was not extended to a complete mesh excision to prevent major surgery and the risk of recurrent prolapse. Particularly, the area of the mesh excision was inspected with the rendezvous technique (light source vaginally, laparoscopic pelvic view with laparoscopic light source switched off) to identify the area of mesh excision from the intra-abdominal area. Sigmoid and rectum were distant to this area, suggesting that no bowel lesion occurred. No complications occurred in the postoperative course. In the follow-up visit 6 months postoperatively the patient was asymptomatic, and the vaginal examination was uneventful with no recurrent erosion. Although improved oversight and richness of detail achieved by the vaginal SILS method is helpful in patients like our case with a suspended vaginal vault, its costs need to be balanced against conventional vaginal approaches (e.g., use of a Lonestar retractor). CONCLUSION The SILS trocar and laparoscope used (SILS Port; Covidien, New Haven, CT) vaginally provide a magnificent and detailed view to allow for exact preparation by means of microinvasive instruments in vaginal surgery, even more in patients with a suspended vaginal vault where access to the apex can be tricky. The "pneumovagina" created by CO2 insufflation further helps to expose the vaginal apex. The rendezvous technique can additionally be used to identify intra-abominal lesions.

Objective: Skin-sparing mastectomy (SSM) with immediate heterologous reconstruction is a safe oncological option in surgical therapy of early breast cancer. Permacol® is an acellular dermal matrix (ADM) placed between the implant and the skin to improve lower pole projection and implant coverage. The aim of our study was to evaluate the outcome with a focus on patient satisfaction after six months and to analyze physical changes of ADM. Methods: 10 patients who underwent SSM with Permacol® were analyzed retrospectively. All patients were followed using a satisfaction questionnaire and an ultrasound evaluation of the tissue thickness of the pectoralis muscle and the Permacol®. Results: No intraoperative complications were observed. One patient required removal of the implant for necrosis after three months. Half of the patients underwent secondary corrective surgery. A statistically significant thinning of the pectoralis muscle was observed, compared to the thickening of the Permacol®. A majority of the patients were satisfied with the operation and we found a correlation between lower body mass index and patient satisfaction. Conclusion: In our small case series Permacol®-assisted immediate reconstruction is shown to be an option for selected cases. Physical changes of Permacol® result in a symmetrical coverage of the implant, which may improve cosmetic outcome.

INTRODUCTION AND HYPOTHESIS Mixed urinary incontinence (MUI), defined as mixed symptoms of stress urinary incontinence (SUI) and overactive bladder (OAB), is a difficult entity if conservative treatment has failed. Cure rates are low compared with SUI, particularly the OAB component, may deteriorate after sling insertion. Bulking agents pose an appealing alternative for the treatment of MUI. They have shown beneficial effect in small case studies, but larger series are lacking. The aim of this prospective study was an analysis of treatment efficacy and safety profile of the bulking agent, Bulkamid, in female patients with MUI. METHODS One hundred fifty-four women with MUI symptoms (components of SUI/OAB within the limits of 60-40% either way) received bulking therapy with polyacrylamide hydrogel (Bulkamid). Patients were followed-up 3 months postoperatively. Primary outcome was the domain Incontinence impact on the King's Health Questionnaire (KHQ). Secondary outcomes were the other KHQ domains, visual analog scale (VAS), and International Continence Society (ICS) standardized pad weight test as objective measurement of incontinence. RESULTS Statistically significant improvements were found for all KHQ domains, pad weight test, and the visual analog scale (VAS) before and after bulking. Overall complication rate was 13%. CONCLUSIONS This study has shown improvement in MUI after bulking therapy according to both subjective and objective outcomes. We can advocate bulking therapy for treating MUI, as it is simple and safe and shows both objective and subjective improvement and relief. Long-term results (up to 1 year) are awaited.

Background and purposeIndividualized therapy in endometrial cancer, the most common gynaecologic cancer in the developed world, focuses on identifying specific molecular subtypes. Mutations in the exonuclease domain of the DNA polymerase epsilon (POLE) gene define one such subtype, which causes an ultra-mutated tumour phenotype. These tumours may have an improved progression-free survival and may be receptive to specific therapies. However, the clinical phenotype of these tumours is unknown. The objective of this study was to evaluate the clinical and genetic features of POLE-mutated tumours from a large cohort of women whose cases are characterized by: (1) the availability of detailed clinical and lifestyle data; (2) mutation analysis; and (3) long-term follow-up.MethodsA total of 604 patients with endometrial cancer were included in the study. Data from a detailed questionnaire, including lifestyle and family history information, provided extensive pertinent information on the patients. Sequencing of exons 9-14 of the POLE gene was performed. Follow-up data were gathered and analysed.ResultsHotspot pathogenic POLE mutations were identified in N = 38/599 patients (6.3%). Patients with a POLE-mutated tumour were significantly younger, were more often nulliparous, and had a history of smoking. POLE-mutated tumours were more frequently aneuploid. Prognosis for patients with hotspot POLE-mutated tumours was significantly better in comparison with patients with non-mutated tumours; however careful selection of pathogenic mutations is essential to the definition of this prognostically favourable group.ConclusionsThis study demonstrates that POLE-mutated endometrial cancer is significantly associated with previously unknown clinicopathologic characteristics. Outcome in POLE-mutated tumours was excellent in cases with hotspot mutations. Our results suggest that prediction of excellent outcome in cases of POLE-mutated EMCA should be restricted to cases of EMCA with hotspot mutations until further data are available on the rising number of mutations with unknown significance.

We present a case of laparoscopic surgical management of an iatrogenic lymphorrhea using indocyanine green (ICG). A case of a patient who developed recurrent symptomatic lymphorrhea after laparoscopic radical hysterectomy and bilateral pelvic lymphadenectomy for an early stage cervical cancer is presented. Intraoperative bipedal interdigital subcutaneous injection of ICG exactly localized the disrupted lymphatic duct on fluorescence imaging performed with a near-infrared laparoscopic fluorescent optic device, thus allowing a successful surgical repair.

Objective To investigate the effect of gonadotropin-releasing hormone analogues (GnRHa) on the peritoneal fluid microenvironment in women with endometriosis. Study design Peritoneal fluid was collected from 85 women with severe endometriosis (rAFS stage III and IV) during laparoscopic surgery during the proliferative phase. Prior to surgery clinical data were collected. The concentrations of specific markers for endometriosis in the peritoneal fluid were determined using an ELISA and a comparison between peritoneal fluid markers in women using GnRHa and no hormonal treatment was performed using a non-parametric Mann–Whitney U test. Results The study included peritoneal fluid from 39 patients who had been administered GnRHa (Zoladex ® ) in the three months prior to surgery and 46 from women with no hormonal treatment in this period. Concentrations of IL-8, PAPP-A, glycodelin-A and midkine were significantly reduced in the GnRHa treatment group compared to women receiving no hormonal treatment. RANTES, MCP-1, ENA-78, TNF-α, OPG, IP-10 and defensin showed no significant change between the two groups. Conclusions GnRHa mediate a significant regression in the inflammatory nature of the peritoneal microenvironment in women with endometriosis.

Objective . To assess the accuracy and reproducibility of robot-assisted laparoscopic abdominal fertility sparing radical trachelectomy in women with early stage cervical cancer. Methods . Relevant prospective clinical data from 13 consecutive women planned for robotic radical trachelectomy between 2007 and 2012 were compared with retrospective data from 12 consecutive women planned for vaginal radical trachelectomy between 2000 and 2007. The first follow up on all women included a similar vaginal ultrasonographic measurement of the remaining cervical length and the position of the cerclage, enabling a direct comparison. Peri- and postoperative clinical data were evaluated. Results . The remaining cervical length was equal between the robotic and vaginal procedures (mean 11mm, range 8–13mm; mean 11mm, range 5–19mm respectively, p =0.92). The distance from the cerclage to the inner cervical os was significantly shorter and less variable in the robot group (robot mean 2mm, range of 1–4mm, vaginal mean 4mm, range 2–7mm, p =0.003). Rejection of the cerclage ( n =3) and/or cervical stenosis ( n =3) was diagnosed in four women, all of whom in the vaginal group, between one and 13months after surgery. Conclusions . Robotic trachelectomy is equally reproducible and accurate as the vaginal trachelectomy in terms of the remaining cervical length and results in a significantly more precise placement of the cerclage.

PURPOSE To compare two surgical strategies used to identify lymph node metastases in patients with preoperative diagnosis of complex atypical hyperplasia (CAH), grade 1 and 2 endometrial cancer (EC). METHODS Data on patients with preoperative diagnosis of CAH, grade 1 and 2 EC undergoing laparoscopic indocyanine green (ICG) sentinel lymph node (SLN) mapping followed by frozen section of the uterus were collected. When risk factors were identified at frozen section, patients were subjected to a systematic lymphadenectomy. False negative (FN) rates, negative predictive values (NPV), positive predictive values (PPV) and correlation with stage IIIC EC were calculated for the systematic lymphadenectomy based on frozen section of the uterus and for the SLN mapping. RESULTS Six (9.5%) out of 63 patients had lymph nodal metastases. Based on frozen section of the uterus, 22 (34.9%) and 15 (22.2%) patients underwent a pelvic and a pelvic and paraaortic lymphadenectomy, respectively. Five patients with stage IIIC disease were identified with a FN rate of 16.7% and a NPV and PPV of 97.6 and 27.3%, respectively. Overall and bilateral detection rates of ICG SLN mapping were 100 and 97.6%, respectively; no FN were recorded. The identification of patients with stage IIIC disease with ICG SLN mapping showed a NPV and PPV of 100%. Correlation between indication to lymphadenectomy and stage IIIC disease was poor (κ = 0.244) when based on frozen section of the uterus and excellent (κ = 1) when based on SLN mapping. CONCLUSIONS ICG SLN mapping reduces the number of unnecessary systematic lymphadenectomies and the risk of underdiagnosing patients with metastatic lymph nodes.

BACKGROUND In patients with a diagnosis of occult cervical cancer made on a hysterectomy specimen after surgery for a benign indication, lymph node assessment is crucial to determine treatment. We aimed to compare sentinel lymph node (SLN) mapping between patients with postoperative diagnosis of occult cervical carcinoma and patients with cervical cancer and uterus in situ. METHODS A retrospective analysis of cervical cancer patients International Federation of Gynecology and Obstetrics (FIGO) stage IA-IIA disease undergoing laparoscopic SLN mapping was performed. Patients were divided into two groups: those with a diagnosis of occult cervical cancer made on a hysterectomy specimen (group 1) and those with a diagnosis of cervical cancer and uterus in situ (group 2). Tracers used for SLN mapping included technetium-99m ((99m)Tc), blue dye, and indocyanine green. After detection and excision, the SLN was sent for frozen section analysis, and the planned surgical procedure was aborted in case of metastatic disease in favor of a chemoradiotherapeutic treatment. RESULTS Groups 1 and 2 included 9 and 62 patients, respectively. Clinicopathologic characteristics were similar among the two groups. Overall and bilateral detection rates were 66.6 and 33.3 and 95.1 and 87 % in groups 1 and 2, respectively (p

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.

Despite the dramatic improvements achieved in cancer treatment through a better understanding of the tumor biology, ovarian cancer is still characterized by a poor prognosis: most patients diagnosed with this disease will ultimately die from it. In various clinical trials conducted over a time span of two decades, new combinations of conventional chemotherapy regimens have failed to achieve significant improvements in oncologic outcome in ovarian cancer patients. We have now entered an era of "personalized medicine" in which new medications are designed to specifically target molecular pathways involved in carcinogenesis and cancer progression. Encouraging results in different tumor types have been reported, applying an increasing number of target therapies that are still under evaluation. In this setting, one of the most successfully targeted molecular pathways is tumor angiogenesis. Bevacizumab, a monoclonal antibody binding vascular endothelial growth factor (VEGF), has been recently incorporated in the treatment of primary and recurrent ovarian cancer patients after multiple phase III randomized controlled trials have proven its clinical benefit. Based on these positive results, more anti-angiogenic molecules using different mechanisms of action have been developed and are currently under investigation. Among these molecules, the tyrosine kinases inhibitors are probably the most promising ones. Cediranib is a tyrosine kinase inhibitor targeting VEGF receptors that has been tested in various trials with promising results. The aim of this manuscript is to review the current role of cediranib in the treatment of ovarian cancer and to present an overview of the ongoing clinical trials in this setting.

OBJECTIVE Bladder outlet obstruction may occur after any incontinence surgery and may present as OAB, hesitancy and or the feeling of incomplete emptying. Aim of this study was to analyze the clinical and urodynamical outcome after urethrolysis in patients presenting with various clinical symptoms after Burch colposuspension for stress urinary incontinence. STUDY DESIGN Between January 2005 and December 2014, all patients who presented with symptoms and with bladder outlet obstruction were included. All patients had undergone Burch or Cowan colposuspension for stress urinary incontinence previously. Primary endpoint was the visual analogue scale (VAS) as measurement of patient perceived disease impact. Secondary endpoints were the various domains of the King's Health Questionnaire, urodynamic parameters as detrusor pressure at maximum flow, residual urine and sonographic bladder wall thickness before and six months after intervention. RESULTS Seventy-two female patients were included in this study whereof 42 suffered from urgency and urge incontinence, 20 from hesitancy and/or slow stream, seven from residual urine of more than 100ml and three from a combination of urgency and residual urine. VAS improved significantly (p

Background: The traditional surgical treatment for cervical insufficiency is vaginal placement of a cervical cerclage. However, in a small number of cases a vaginal approach is not possible. A transabdominal approach can become an option for these patients. Laparoscopic cervical cerclage is associated with good pregnancy outcomes but comes at the cost of a higher risk of serious surgical complications. The aim of the present study was to evaluate intraoperative and long-term pregnancy outcomes after laparoscopic cervical cerclage, performed either as an interval procedure or during early pregnancy, using a new device with a blunt grasper and a flexible tip. Methods: All women who underwent laparoscopic cervical cerclage for cervical insufficiency in our institution using the Goldfinger® device (Ethicon Endo Surgery, Somerville, NJ, USA) between January 2008 and March 2014 were included in the study. Data were collected from the patients' medical records and included complications during and after the above-described procedure. Results: Eighteen women were included in the study. Of these, six were pregnant at the time of laparoscopic cervical cerclage. Mean duration of surgery was 55 ± 10 minutes. No serious intraoperative or postoperative complications occurred. All patients were discharged at 2.6 ± 0.9 days after surgery. One pregnancy ended in a miscarriage at 12 weeks of gestation. All other pregnancies ended at term (> 37 weeks of gestation) with good perinatal and maternal outcomes. Summary: Performing a laparoscopic cervical cerclage using a blunt grasper device with a flexible tip does not increase intraoperative complications, particularly in early pregnancy. We believe that use of this device, which is characterized by increased maneuverability, could be an important option to avoid intraoperative complications if surgical access is limited due to the anatomical situation. However, because of the small sample size, further studies are needed to confirm our findings., Die Therapie einer Zervixinsuffizienz besteht aktuell in der vaginalen Cerclage. In einigen wenigen Fällen ist dies nicht möglich, sodass die laparoskopische zervikale Cerclage eine Therapieoption sein kann, die aber mit einem höheren Risiko intraoperativer Komplikationen assoziiert ist. Das Ziel unserer Studie besteht darin, sowohl die intraoperative Sicherheit als auch die Langzeitergebnisse der mit einem „neuen“ Instrument durchgeführten laparoskopischen zervikalen Cerclage – präkonzeptionell oder in der Frühschwangerschaft durchgeführt – zu evaluieren. Methoden: Eingeschlossen wurden alle Frauen, bei denen zwischen Januar 2008 und März 2014 eine laparoskopische zervikale Cerclage mittels dem Goldfinger®-Instrument (Ethicon Endo Surgery, Somerville, NJ, USA) aufgrund einer Zervixinsuffizienz durchgeführt wurde. Es wurden alle Daten der Patientinnen inklusive der peri- und postoperativen Komplikationen der oben beschriebenen Operationstechniken gesammelt. Ergebnisse: Achtzehn Frauen wurden in unsere Studie eingeschlossen. Zum Zeitpunkt der durchgeführten laparoskopischen zervikalen Cerclage waren 6 Patientinnen schwanger. Die mittlere Operationsdauer betrug 55 ± 10 Minuten. Es traten keine ernsthaften peri- und postoperativen Komplikationen auf. Alle Patientinnen konnten nach 2,6 ± 0,9 Tagen aus dem Spital entlassen werden. Bei einer Patientin kam es zu einem Abort in der 12. SSW. Bei allen anderen Schwangerschaften kam es zur Geburt am Termin (> 37. SSW) mit gutem perinatalen und maternalen Outcome. Zusammenfassung: Das Durchführen einer laparoskopischen zervikalen Cerclage mit diesem flexiblen Instrument scheint die intraoperative Komplikationsrate – insbesondere in der Frühschwangerschaft – nicht zu erhöhen. Die Verwendung des flexiblen und sehr gut manövrierbaren Instruments ist eine interessante Möglichkeit bei Patientinnen mit anatomisch schwierigen Verhältnissen und der Notwendigkeit einer zervikalen Cerclage. Um die guten Resultate zu bestätigen sind weitere Studien notwendig.

Objective To analyze the prevalence of urinary tract endometriosis (UTE) in patients with deep infiltrating endometriosis (DIE) and to define potential criteria for preoperative workup. Design Retrospective study. Setting University hospital. Patient(s) Six hundred ninety-seven patients with endometriosis. Intervention(s) Excision of all endometriotic lesions. Main Outcome Measure(s) Correlation of preoperative features and intraoperative findings in patients with UTE. Result(s) Out of 213 patients presenting DIE, 52.6% suffered from UTE. In patients with ureteral endometriosis, symptoms were not specific. Among the patients with bladder endometriosis, 68.8% complained of urinary symptoms compared to 7.9% in the group of patients without UTE. In patients with rectovaginal endometriosis, the probability of ureterolysis showed a linear correlation with the size of the nodule. We found that 3 cm in diameter provided a specific cutoff value for the likelihood of ureteric involvement. Conclusion(s) The prevalence of UTE has often been underestimated. Preoperative questioning is important in the search for bladder endometriosis. The size of the nodule is one of the few reliable criteria in preoperative assessment that can suggest ureteric involvement. We propose a classification of ureteral endometriosis that will allow the standardization of terminology and help to compare the outcome of different surgical treatment in randomized studies.

Purpose: Congenital uterine anomalies often remain asymptomatic until they cause problems, for example during pregnancy. We studied the diagnostic aspects of two- and three-dimensional ultrasound and MRI. Materials and Methods: 63 women referred for suspected uterine anomalies were studied: In the first group (until July 2008) with 2 D-US and MRI, in the second group (from August 2008) additionally with 3 D-US; these women also had diagnostic or therapeutic operative confirmation. In the third group, only 3D-US was used. Results: In all women 3D-US was possible and successful. The most common anomaly was a subseptate uterus, while a septate uterus was less frequent, and uterus bicornis (unicollis) and uterus didelphys (bicornis bicollis) were rare. The women in the first two groups all underwent at least diagnostic hysteroscopy, and some (subseptate or septate uterus) underwent operative hysteroscopy. After preoperative volume imaging, laparoscopies were required less often. 3D-US diagnoses as judged by intraoperative findings were correct in 100 % of cases, while the MRI diagnoses in the same group were correct in only 7/13 cases. Conclusion: Since the introduction of volume imaging (MRI, later 3 D-US), laparoscopy during hysteroscopic septum resection was not necessary in the majority of cases. 3D-US brings the diagnostics of uterine anomalies back into the hands of the gynecologist and can provide the gynecological surgeon with a higher subjective degree of certainty during operative hysteroscopy.

Summary OBJECTIVE: Caesarean section (CS) rates have risen over the past two decades. The aim of this observational study was to identify time-dependent variations in CS and vaginal delivery rates over a period of 11 years. METHOD: All deliveries (13,701 deliveries during the period 1999–2009) at the University Women’s Hospital Bern were analysed using an internationally standardised and approved ten-group classification system. Caesarean sections on maternal request (CSMR) were evaluated separately. RESULTS: We detected an overall CS rate of 36.6% and an increase in the CS rate over time (p

Highlights • We present a case with a retrorectal tumor and discuss the approach. • The minimal invasive approach is demonstrated. • The importance of preoperative diagnostics is presented, especially if the location is found unexpectedly., INTRODUCTION Retrorectal tumors are uncommon and the etiology diverse. Literature to define the preoperative diagnosis and plan the intraoperative management are uncommon. PRESENTATION OF CASE We describe a case of a 44 year old patient with a laparoscopic approach for the removal of a retrorectal tumor and emphasize on the preoperative diagnostics and the intraoperative, minimal invasive approach. DISCUSSION Especially because these tumors are rare and often an incidental finding in gynecologic surgery, it is important to know the various differential diagnoses and its consequences with the laparoscopic approach. CONCLUSION We suggest the laparoscopic approach in cases of retroperitoneal cysts of unknown origin is ideal also because anatomic structures, mostly nerves, can be easily spared.

Introduction: Lymphedema is a frequent complication of local treatment for breast cancer. Substantial differences in the incidence of lymphedema have been reported depending on the extent of surgery, presence of lymph node metastasis and postoperative radiotherapy. The classical treatment of lymphedema includes manual lymph drainage and compressive bandages. No pharmacological treatment has been shown to be effective. In animal experiments extracorporeal shock wave therapy (ESWT) has been shown to stimulate angiogenesis and lymphatic vessel regeneration. However, whether ESWT reduces lymphedema after axillary lymphadenectomy is unknown. Patients and Method: We randomized patients with lymphedema after axillary lymphadenectomy (2004 to 2011) into a treatment and a placebo group. Informed consent was obtained from all patients. All but one patient had at least one positive lymph node. A mean of 21.9 (5-43) lymph nodes were removed. 8/10 had an adjuvant radiotherapy of the axilla. ESWT of the whole edematous limb was performed once a week for 10 weeks (2000 shots, energy density 0,25-0,69 mJ/mm2). The placebo group underwent similar treatment, but the shock waves were absorbed in the probe. At baseline and at the end of treatment a clinical and oncological control was performed, including tolerability of the therapy (pain, local skin changes or infections) and oncological safety (recurrence rate). The response to ESWT was measured by volumetry (water displacement of the whole arm) and peripheral quantitative computed tomography (pQCT, change in total cross sectional area of the most swollen part of the arm). Also questionnaires on subjective body feeling, activity score and body image were applied. Results: We report the preliminary results of the first 10 patients (placebo n = 5, verum n = 5) after 10 weeks. The median change water displacement volume in the verum group corresponded to -192.5 ml (25% percentile: -366.3 ml, 75% percentile -148.8 ml) vs. -12.5 ml (25% percentile: -192.8 ml, 75% percentile: 147.5 ml) in the placebo group (p-value for Mann-Whitney U test: 0.093). Cross sectional area decreased by -3.05% (25% percentile: -8.73%, 75% percentile: 1.49%) in the verum group vs. -1.36% (25% percentile -3.47%, 75% percentile 4.20%) in the placebo group (p-value: 0.394). No treatment had to be interrupted due to local complications. Conclusion: ESWT is well tolerated in patients treated for lymphedema after axillary lymphadenectomy. Our preliminary results show a promising trend towards both objective and subjective improvement of the lymphedema. The statistical significance of these improvements has to be confirmed after inclusion of all patients (N = 30). Citation Information: Cancer Res 2013;73(24 Suppl): Abstract nr P1-01-14.

BACKGROUND AND PURPOSE (99)TC 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 (99)Tc 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.
