The etiopathogenesis of endometriosis is a multifactorial process resulting in a heterogeneous disease. Considering that endometriosis etiology and pathogenesis are still far from being fully ...elucidated, the current review aims to offer a comprehensive summary of the available evidence. We performed a narrative review synthesizing the findings of the English literature retrieved from computerized databases from inception to June 2019, using the Medical Subject Headings (MeSH) unique ID term "Endometriosis" (ID:D004715) with "Etiology" (ID:Q000209), "Immunology" (ID:Q000276), "Genetics" (ID:D005823) and "Epigenesis, Genetic" (ID:D044127). Endometriosis may origin from Müllerian or non-Müllerian stem cells including those from the endometrial basal layer, Müllerian remnants, bone marrow, or the peritoneum. The innate ability of endometrial stem cells to regenerate cyclically seems to play a key role, as well as the dysregulated hormonal pathways. The presence of such cells in the peritoneal cavity and what leads to the development of endometriosis is a complex process with a large number of interconnected factors, potentially both inherited and acquired. Genetic predisposition is complex and related to the combined action of several genes with limited influence. The epigenetic mechanisms control many of the processes involved in the immunologic, immunohistochemical, histological, and biological aberrations that characterize the eutopic and ectopic endometrium in affected patients. However, what triggers such alterations is not clear and may be both genetically and epigenetically inherited, or it may be acquired by the particular combination of several elements such as the persistent peritoneal menstrual reflux as well as exogenous factors. The heterogeneity of endometriosis and the different contexts in which it develops suggest that a single etiopathogenetic model is not sufficient to explain its complex pathobiology.
Purpose
Despite long and intensive research, endometriosis remains one of the leading causes of morbidity among premenopausal women. The majority of endometriosis-related ovarian carcinomas occur in ...the presence of atypical ovarian endometriosis. Nevertheless, despite the increased incidence of ovarian cancer in patients with endometriosis, our knowledge of the risk factors and mechanisms is still incomplete.
Method
Narrative overview, synthesizing the recent findings of literature retrieved from databases.
Results
Herein, we reviewed and summarized the most recent knowledge regarding endometriosis and ovarian cancer.
Conclusion
The evidence showing that patients with endometriosis have a higher risk of developing ovarian cancer is compelling. However, the question of how much higher the absolute risk is, is not fully clear.
We investigated menstrual irregularities after the first and second doses of the COVID-19 vaccine. Women answered a customised online questionnaire (ClinicalTrial.gov ID: NCT05083065) aimed to assess ...the vaccine type, the phase of the menstrual cycle during which the vaccine was administered, the occurrence of menstrual irregularities after the first and second doses, and how long this effect lasted. We excluded women with gynaecological and non-gynaecological diseases, undergoing hormonal and non-hormonal treatments, in perimenopause or menopause, as well as those who had irregular menstrual cycles in the last 12 months before vaccine administration. According to our data analysis, approximately 50–60% of reproductive-age women who received the first dose of the COVID-19 vaccine reported menstrual cycle irregularities, regardless of the type of administered vaccine. The occurrence of menstrual irregularities seems to be slightly higher (60–70%) after the second dose. Menstrual irregularities after both the first and second doses of the vaccine were found to self-resolve in approximately half the cases within two months. Based on these results, we suggest to consider these elements during the counselling of women who receive the COVID-19 vaccine, letting them know about the potential occurrence of temporary and self-limiting menstrual cycle irregularities in the subsequent month(s).
Endometriosis is an estrogen-dependent disease defined by the presence and growth of functional endometrial-like tissue, glands and stroma, outside the uterine cavity. Macrophages are broadly ...classified into pro-inflammatory M1 macrophages, and M2 macrophages, which have selective anti-inflammatory and pro-fibrotic activities and are able to induce immunotolerance and angiogenesis. Based on these elements, the aim of our study was to evaluate CD14

M2 macrophages in tissue samples from ovarian endometriomas of women affected by endometriosis at different stages of the disease. For each patient, we collected a biological sample of the cyst (ovarian endometriomas for cases and ovarian functional cyst for controls) during laparoscopy. We found that the number of both M1 and M2 macrophages was significantly higher in endometriosis group than controls, regardless of stage (p < .0001 for each stage versus controls). Moreover, our data analysis shows a trend in progressive decrease of M1 macrophages from stage I to stage IV; on the contrary, M2 macrophages show a specular trend compared to M1 macrophages, with a progressive increase from stage I to stage IV. This may contribute to the pro-inflammatory microenvironment in the early stages of the disease, and to the pro-fibrotic activity of the advanced stages.

Systematic paraaortic and bilateral pelvic lymphadenectomy is the standard of a comprehensive surgical staging in presumed early epithelial ovarian cancer, but no prospective randomized evidence ...suggests a possible therapeutic value. Moreover, this procedure is associated with potential severe morbidity. The Sentinel Lymph Nodes in Early-Stage Ovarian Cancer trial is a prospective study designed to test whether sentinel node detection can accurately predict nodal status in a cohort of women with early epithelial ovarian cancer.
We here present the results of the first part of the Sentinel Lymph Nodes in Early-Stage Ovarian Cancer trial, regarding the feasibility of the sentinel lymph node technique and the preliminary findings regarding its safety and accuracy.
The Sentinel Lymph Nodes in Early-Stage Ovarian Cancer trial is a prospective, phase II, single-arm study included patients with presumed stages I–II epithelial ovarian cancer planned for immediate or delayed minimally invasive comprehensive staging. The ovarian pedicle is injected with 2 mL of a 1.25 mg/mL indocyanine green solution. The pelvic and lumboaortic retroperitoneum is then accessed and inspected to identify and remove sentinel nodes. After sentinel node procedure, staging is completed including systematic pelvic and paraaortic lymphadenectomy. Assuming a sensitivity of 98.5% in predicting positive sentinel lymph nodes at histology, a pathological lymph node prevalence of 14.2%, a precision of estimate (ie, the maximum marginal error) d = 5%, a type I error α = 0.05, a sample size of 160 patients is needed to test the general hypothesis. Here we present the preliminary results on the first 31 patients enrolled.
Thirty-one patients were included. Sentinel node was identified in 21 patients (detection rate, 67.7%). The detection rate was significantly higher in women undergoing immediate vs delayed staging (88.9% vs 41.7%, P = .003). Four patients had positive nodes. In all the patients with lymphatic dissemination, a positive sentinel node was identified (sensitivity, 100%; false-negative rate, 0%; negative predictive value, 100%). One (3.2%) intra- and 2 (6.5%) postoperative grade I complications occurred.
Our data show that the detection of sentinel node in early epithelial ovarian cancer is low when patients are submitted to delayed-staging surgery. However, sentinel node procedure is feasible and has the potential to provide reliable and useful information on nodal status and may allow the avoidance of systematic lymphadenectomy in the majority of patients.
The aim of the present review is to summarize the current evidence on the role of pelvic and para‐aortic lymphadenectomy in endometrial cancer. In 1988, the International Federation of Obstetrics and ...Gynecology recommended surgical staging for endometrial cancer patients. However, 25 years later, the role of lymph node dissection remains controversial. Although the findings of two large independent randomized trials suggested that pelvic lymphadenectomy provides only adjunctive morbidity with no clear influence on survival outcomes, the studies have many pitfalls that limit interpretation of the results. Theoretically, lymphadenectomy may help identify patients with metastatic dissemination, who may benefit from adjuvant therapy, thus reducing radiation‐related morbidity. Also, lymphadenectomy may eradicate metastatic disease. Because lymphatic spread is relatively uncommon, our main effort should be directed at identifying patients who may potentially benefit from lymph node dissection, thus reducing the rate of unnecessary treatment and associated morbidity. This review will discuss the role of lymphadenectomy in endometrial cancer, focusing on patient selection, extension of the surgical procedure, postoperative outcomes, quality of life and costs. The need for new surgical studies and efficacious systemic drugs is recommended.
Abstract Context Surgery represents the mainstay of treatment for pelvic organ prolapse (POP). Among different surgical procedures, abdominal sacrocolpopexy (SC) is the gold standard for apical or ...multicompartmental POP. Research has recently focused on the role of robot-assisted sacrocolpopexy (RASC). Objective To conduct a systematic review on the outcomes of RASC. Evidence acquisition PubMed, Scopus, and Web of Science databases as well as ClinicalTrials.gov were searched for English-language literature on RASC. A total of 509 articles were screened; 50 (10%) were selected, and 27 (5%) were included. Studies were evaluated per the Grading of Recommendations, Assessment, Development, and Evaluation system and the European Association of Urology guidelines. Evidence synthesis Overall, data on 1488 RASCs were collected from 27 studies, published from 2006 to 2013. Objective and subjective cures ranged from 84% to 100% and from 92% to 95%, respectively. Conversion rate to open surgery was <1% (range: 0–5%). Intraoperative, severe postoperative complications, and mesh erosion rates were 3% (range: 0–19%), 2% (range: 0–8%), and 2% (range: 0–8%), respectively. Surgical-related outcomes have improved with increased experience, with an estimated learning curve of about 10–20 procedures. Laparoscopic SC is less costly than RASC, although the latter has lower costs than abdominal SC. Conclusions RASC is a safe and feasible procedure for POP; it allows the execution of complex surgical steps via minimally invasive surgery without medium- and long-term anatomic detriments. Further prospective studies are needed to confirm these findings. Patient summary We looked at the outcomes of robotic sacrocolpopexy for prolapse. We found that the use of robotic technology is safe and effective for the treatment of prolapse in women.
Objective The objective of the study was to prospectively evaluate the accuracy of laparoscopy performed in satellite centers (SCs) to describe intraabdominal diffusion of advanced ovarian cancer ...(AOC). Study Design Patients with a clinical/radiological suspicion of AOC were included in the protocol. SCs were selected among those surgeons, spending a short intensive training period at the coordinator center (CC) to learn the application of staging laparoscopy (S-LPS) in AOC. All women underwent S-LPS at the SCs, and the surgical procedure was recorded and blindly reviewed at the CC. Calculating specificity, positive and negative predictive values, and the accuracy for each parameter with respect to the CC assessed the diagnostic performance of S-LPS. The Cohen's kappa was used to test the interobserver agreement of each parameter. Results One hundred sixty-eight cases were considered eligible for the study. A per-protocol analysis was performed on 120 cases. The worst laparoscopic assessable feature was mesenteric retraction, whereas the remaining variables ranged from 99.2% (peritoneal carcinomatosis) to 90% (bowel infiltration). All but 1 SC (SC number 4) reached an accuracy rate of 80% or greater for both single parameters and overall score. The Cohen's kappa and the P value for overall predicitive index value were 0.685 and .01, respectively, but improved to 0.773 and .388 after removing the SC number 4 from the analysis. Conclusion S-LPS allows an accurate and reliable assessment of intraperitoneal diffusion of disease in AOC patients in trained gynecological oncology centers.
Objective To determine the incidence of vaginal cuff dehiscence after minimally invasive hysterectomy, we reported our series of total laparoscopic hysterectomies with transvaginal colporraphy. Study ...Design We then conducted a systematic search of PubMed to retrieve published series of laparoscopic and robotic hysterectomies, in which different techniques for vaginal cuff closure were used. Results In our study group, vaginal cuff dehiscence occurred in 2 of 665 (0.3%) patients. Our literature search identified 57 articles, for a total of 13,030 endoscopic hysterectomies. Ninety-one postoperative vaginal separations were reported (0.66%). The pooled incidence of vaginal dehiscence was lower for transvaginal cuff closure (0.18%) than for both laparoscopic (0.64%; odds ratio OR, 0.28; 95% confidence interval CI, 0.12–0.65) and robotic (1.64%; OR, 0.11; 95% CI, 0.04–0.26) colporraphy. Laparoscopic cuff closure was associated with a lower risk of dehiscence than robotic closure (OR, 0.38; 95% CI, 0.28–0.6). Conclusion Current evidence indicates that transvaginal colporraphy after total laparoscopic hysterectomy is associated with a 3- and 9-fold reduction in risk of vaginal cuff dehiscence compared with laparoscopic and robotic suture, respectively.
To compare perioperative and long-term outcomes related to laparoscopic and open abdominal surgical management of cervical cancer.
Propensity-matched comparison of prospectively collected data ...(Canadian Task Force classification II-1).
University teaching hospital.
Sixty-five propensity-matched patient pairs (130 patients) undergoing either laparoscopy or open abdominal surgical procedures to treat cervical cancer.
Radical hysterectomy plus lymphadenectomy was performed via the laparoscopic (LRH) or open abdominal approach (RAH).
Baseline characteristics of the study populations were similar. In the LRH group the procedure was converted to open surgery in 2 patients (2%). Compared with the RAH group, patients undergoing LRH experienced less blood loss (200 vs 500 mL; p < .001), a lower transfusion rate (6% vs 22%; p = .02), similar operative time (245 vs 259.5 minutes; p = .26), and shorter length of hospital stay (4 vs 8 days; p < .001). No between-group differences in intraoperative complications were recorded (p = 1.0); however, a trend toward a lower postoperative complication rate (Accordion system grade ≥ 3) was observed for LRH compared with RAH (4 patients 6%) vs 12 patients 18%; p = .06). Five-year disease-free survival (p = .6, log-rank test) and overall survival (p = .31, log-rank test) did not differ statistically between women undergoing LRH or RAH.
Laparoscopy ensures the same results as open surgery insofar as radicality and long-term survival. Use of the laparoscopic approach is associated with improved short-term results, minimizing the occurrence of severe postoperative complications.
