Endometriosis-Related Ovarian Cancer: Where Are We Now? A Narrative Review towards a Pragmatic Approach

BACKGROUND

Endometriosis affects more than 10% of reproductive-aged women, causing pelvic pain and infertility. Despite the benign nature of endometriosis, ovarian endometriomas carry a higher risk of developing endometrioid carcinomas (EnOCs) and clear cell ovarian carcinomas (CCCs). Atypical endometriosis, defined as cytological atypia resembling intraepithelial cancer, is considered the precursor of endometriosis-associated ovarian cancer (EAOC). This narrative review aims to provide an overview of EAOC, proposing a practical approach to clinical and therapeutic decision making.

METHODS

An electronic literature search was conducted from inception up to January 2023, using the MEDLINE database via PubMed to evaluate the existing literature on EAOC, including its pathogenesis, the diagnostic process, and the therapeutic possibilities, with articles not relevant to the topic or lacking scientific merit being excluded.

RESULTS

Eighty-one articles were included in the review to present the current state of the art regarding EAOC. A pragmatic clinical flowchart is proposed to guide therapeutic decisions and improve patient outcomes.

CONCLUSIONS

Endometriosis patients may have an increased risk of developing EAOC (either EnOC or CCC). Despite not being fully accepted, the concept of AE may reshape the endometriosis-ovarian cancer relationship. Further research is needed to understand the unaddressed issues.

Ovarian tissue transplantation: 10 years of experience at the Bologna University

Objective

The efficiency of ovarian tissue transplantation (OTT) was established in terms of ovarian function recovery (95% of cases), number of live births (over 200 worldwide to date) and induction of puberty. Unfortunately, the lack of international registries and the fact that many centers have not yet reported their outcomes, lead to poor knowledge of the exact fertility data. The aim of the study is to describe our experience with OTT to restore ovarian function and fertility.

Methods

This study was designed as a single-center, observational, retrospective, cohort study that includes women who underwent OTT between December 2012 and June 2023 at our center. After approval by the oncologist/hematologist, a small fragment of ovarian tissue was thawed and analyzed to detect the presence of micrometastases before OTT. Thawed ovarian tissue was grafted laparoscopically at multiple sites, including the remaining ovary and pelvic side wall (orthotopic transplantation) and/or abdominal wall (heterotopic transplantation). After OTT, ovarian function was monitored by hormonal assay, ultrasound and color Doppler at approximately 4-week intervals.

Results

Between December 2012 and June 2023, 30 women performed OTT. Prior to OTT, immunohistochemical and molecular analyses revealed no micrometastases in all thawed ovarian tissue samples. In our series of 30 women, 20 of women were on premature ovarian insufficiency (POI), and the remaining ten cases still had oligomenorrhea and difficulty getting pregnant. Among the women with POI before OTT and at least 6 months follow-up, recovery of endocrine function was observed in all but one woman who underwent orthotopic transplantation (13 of 14 cases), in one out of two women who underwent both orthotopic and heterotopic transplantation (1 of 2 cases) and in all women who underwent heterotopic transplantation (4 of 4 cases). Women who underwent OTT to enhance fertility had no alterations in menstrual cycle and hormonal levels. In total, ten pregnancies were obtained in 25 women, resulting in four live births, two ongoing pregnancies and four spontaneous abortions.

Conclusion

Our data can help patients and physicians in their discussions and decisions about the need and possibilities of preserving fertility.

Extrauterine adenomyoma: A case report and systematic review of the literature

OBJECTIVE

To describe a case of extrauterine adenomyoma (EA) and review all the cases of EA in the literature.

METHODS

Pubmed/MEDLINE, Embase, and Google Scholar from 1807 to December 2022. All studies reporting the histologic diagnosis of an EA. We collected the following data: patient's age, size and location of adenomyoma, presence of endometriosis and adenomyosis, past gynecologic treatment, symptoms, diagnostic imaging, surgical intervention, alternative/adjuvant treatment, associated malignancy, and follow up.

RESULTS

Sixty-seven studies with 85 patients were included. Pain was the most frequent symptom (69.5%). Among diagnostic examinations, ultrasonography was used in 60 out of 81 reported cases, with several radiologic features described. EA was located inside the pelvis in 77.6% of patients. Adnexa were the most frequent site of the disease (24, 28.2%). History of endometriosis or adenomyosis was described in 35 patients (35, 41.2%). Uterine tissue morcellation was reported in 6 of the 85 patients (7.1%). Associated malignancy was detected in 9 out of 85 patients with available data (10.6%). There were two recurrences of disease.

CONCLUSION

Specific imaging features of EA are yet to be described in the literature. History of endometriosis and adenomyosis or uterine tissue morcellation may be suggestive of EA. Histologic examination can give a definitive diagnosis and exclude malignant transformation.

Comparison of perioperative surgical outcomes between contained and free manual vaginal morcellation of large uteruses following total laparoscopic hysterectomy

OBJECTIVE

To compare contained and free manual vaginal morcellation of large uteruses after total laparoscopic hysterectomy (TLH) in women at low risk of uterine malignancy in terms of feasibility and safety.

METHODS

A single-center, observational, retrospective, cohort study was carried out including all patients undergoing TLH requiring manual vaginal morcellation for specimen extraction of large uteruses from January 2015 to August 2021 at the Division of Gynecology and Human Reproduction Physiopathology, IRCCS Azienda Ospedaliero-Universitaria of Bologna, Bologna, Italy. Patients were divided into two groups according to the type of manual vaginal morcellation (contained or free), and compared in terms of demographic, clinical, and perioperative data.

RESULTS

In all, 271 patients were included: 186 (68.6%) in the contained morcellation group and 85 (31.4%) in the free morcellation group. The mean operative time was significantly lower in the contained morcellation group compared with the free morcellation group (median [interquartile range] 130 [45] vs. 155 [60] min; P < 0.001). No significant difference was found in complications related to the morcellation step, overall, intraoperative and postoperative complications, estimated blood loss, length of hospital stays, uterine weight, and rate of occult malignancy between the two groups.

CONCLUSION

Contained vaginal manual morcellation of the uterus after total laparoscopic hysterectomy using a specimen retrieval bag appears to be a safe procedure with significantly lower operative time than free vaginal manual morcellation.

Innovative Cadaveric Technique: Utilising n-Butyl Cyanoacrylate (n-BCA) for Deep Endometriosis Excision Simulation in Minimal Invasive Surgery Training

Background

Our study aimed to create a novel technique using n-butyl cyanoacrylate (n-BCA) for minimal access simulation training on cadavers in deep endometriosis excision.

Objectives

A step-by-step video demonstration of using n-BCA in cadavers to simulate deep endometriosis. This technique is integrated into training sessions using cadavers aimed at enhancing surgical proficiency for deep endometriosis procedures.

Material and Methods

Video article describing using n-BCA in cadavers as a simulation model.

Result

This technique has been used in a hands-on cadaveric training course, and positive feedback supports the recommendation to incorporate this technique.

Conclusion

Utilizing a human cadaver model proves beneficial for enhancing understanding of deep pelvic innervation. Implementing n-BCA in these cadaver dissections demonstrates both reproducibility and safety. This approach significantly contributes to refining surgical expertise in the excision of deep infiltrating endometriosis.

Primary omental pregnancy after in vitro fertilization complicated by hemoperitoneum-how to manage it laparoscopically

OBJECTIVE

To report an uncommon case of primary OP treated laparoscopically. Ectopic pregnancy (EP) is the leading cause of maternal mortality during the first trimester and the incidence increases with assisted reproductive techniques, occurring in approximately 1.5%-2.1% of patients undergoing in vitro fertilization.1 Omental pregnancy (OP) is an extremely rare form of EP accounting for less than 1% of all EPs. OP can be classified as primary or secondary on the basis of Studdiford's criteria2. The preoperative diagnosis of OP is complex and usually occur in acute circumstances during a throughout intraoperative evaluation of the abdomen.3-5 A delayed diagnosis poses a serious threat to the survival of the patient; therefore, it is important to remark that EP can exist in unusual locations and prompt surgical intervention may be necessary.

DESIGN

A step-by-step narrated video of a rare clinical case and description of the surgical procedure.

SETTING

Tertiary Level Academic Hospital "IRCCS Azienda Ospedaliero - Universitaria di Bologna" Bologna, Italy.

PATIENT

A 36-year-old woman was referred to our emergency room because of acute abdominal pain and nausea for 2 hours with no signs of hemodynamic instability. The patient also complained that poor vaginal bleeding appeared during the last 24 hours. The patient has undergone a cycle of in vitro fertilization with an elective single frozen embryo transfer of a blastocyst on day 5, 2 months before. She had no relevant clinical or surgical history. Diffuse abdominal tenderness and a painful uterus at mobilization were appreciated at clinical examination. A massive hemoperitoneum was diagnosed using transvaginal-transabdominal ultrasound, and no uterine or adnexal lesions were identified. The β-human chronic gonadotropin level was 43.861 mIU/mL, and the hemoglobin value was 10.5 g/dL.

INTERVENTIONS

On suspicion of a ruptured EP, after detailed counseling and the acquisition of informed consent, a laparoscopic exploration was planned. First, the hemoperitoneum was evacuated to allow visualization of the abdominal cavity. At pelvic inspection, no EP was found. Throughout the exploration of the abdominal cavity, a 4-cm bluish cystic mass of friable consistency was detected infiltrating the omentum and the mesentery. According to Studdiford's criteria, the diagnosis of a primary OP was established. A careful and complete excision of the ectopic implant was performed with an ultrasonic system and required a considerable hemostatic effort using bipolar energy, endoscopic clips, and mechanical compression. The postoperative course was uneventful. The β-human chronic gonadotropin levels gradually decreased to negative values within 29 days after surgery.

MAIN OUTCOME MEASURE(S)

Omental ectopic pregnancy can be successfully managed with a laparoscopic approach even in an emergency setting.

CONCLUSION

Omental pregnancy can easily be overlooked, even by skilled surgeons, during laparoscopic exploration. It is mandatory that all peritoneal surfaces and the omentum be carefully inspected during surgery in patients without other signs of pelvic EP.We confirm that the patient included in this video gave consent for publication of the video and posting of the video online, including on social media, the journal website, scientific literature websites, and other applicable sites.

Adenomyosis and endometriosis in adolescents and young women with pelvic pain: prevalence and risk factors

BACKGROUND

The aim of this study was to evaluate the prevalence of ultrasound diagnosis of adenomyosis and endometriosis in young women complaining of pelvic pain and to find the symptoms and clinical characteristics associated with these diseases in young women.

METHODS

Cross-sectional study, including 100 young women (14-24 years) with a history of chronic pelvic pain. Women were asked detailed medical hystory and pain symptoms scores (Visual Analogue Scale) and underwent gynecological examination and ultrasound evaluation.

RESULTS

The prevalence of endometriosis and adenomyosis in young women amounted to 25.0% and 46.0%, respectively. A significant correlation was found between ovarian endometriosis and adenomyosis. Dysmenorrhea and dyspareunia were risk factors for adenomyosis. Dyschezia, dyspareunia, chronic pelvic pain, presence of sonographic soft markers suggestive of pelvic adhesions, being a worker and having a previous surgery were risk factors for endometriosis. Young women (20-24 years) had a higher incidence of both adenomyosis and endometriosis than adolescents (14-19 years).

CONCLUSIONS

Our outcomes strengthen the hypothesis of a progressive and common course of the natural history of endometriosis, which initially may manifest with symptoms, then with signs of pelvic adhesions and finally as adenomyosis, ovarian endometriomas or deep infiltrating endometriosis.

Horizontal versus vertical direction of posterior vaginal wall suture after eradication of rectovaginal endometriosis: A multicenter study

OBJECTIVE

To compare safety and effectiveness of two-different directions of suturing the posterior vaginal breach (horizontal [Ho] vs vertical [Ve]) in women undergoing recto-vaginal endometriosis (RVE) nodule resection.

METHODS

A multicenter, retrospective, observational, cohort study was performed including all women of reproductive age undergoing RVE nodule resection between March 2013 and December 2018 at our tertiary centers. Patients included in the present study were divided into two groups based on the direction in suturing the posterior vaginal fornix defect, for comparisons in terms of rate of postoperative complications, pain relief, pain and anatomical recurrence, and length of hospital stay. Univariate comparisons were performed adopting the t test or the Mann-Whitney test for continuous data and the chi-square test or the Fisher exact test for categorical data, with a significant P value set to <0.05.

RESULTS

A total of 101 women were included: 67 in the Ho-group and 34 in the Ve-group. The two groups did not significantly differ in length of hospital stay (6.7 ± 6.9 vs 6.6 ± 3.3 days; P = 0.95), overall postoperative complications (32.8% vs 14.7%; P = 0.05), pain recurrence (35.8% vs 26.5%; P = 0.34) and anatomical recurrence rate (19.4% vs 23.5%; P = 0.62). Conversely, grade III complications were significantly more common in the Ho-group than in the Ve-group (22.7% vs 20%, P = 0.009), while pain relief in terms of deep dyspareunia, dyschezia, dysuria and chronic pelvic pain was more consistent in the Ve-group patients (P = 0.04, 0.04, 0.05, 0.004, respectively).

CONCLUSION

In symptomatic women undergoing RVE nodule resection, Ho suturing of the vaginal breach appears more commonly associated with severe postoperative complications and a worse pain control.

Diagnostic Accuracy of Ultrasound in the Diagnosis of Uterine Leiomyomas and Sarcomas

BACKGROUND

Differential diagnosis between uterine leiomyomas and sarcomas is challenging. Ultrasound shows an uncertain role in the clinical practice given that pooled estimates about its diagnostic accuracy are lacking.

OBJECTIVES

To assess the accuracy of ultrasound in the differential diagnosis between uterine leiomyomas and sarcomas.

DATA SOURCES

A systematic review was performed searching 5 electronic databases (MEDLINE, Web of Sciences, Google Scholar, Scopus, and ClinicalTrial.gov) from their inception to June 2023.

METHODS OF STUDY SELECTION

All peer-reviewed observational or randomized clinical trials that reported an unbiased postoperative histologic diagnosis of uterine leiomyoma or uterine sarcoma that also comprised a preoperative ultrasonographic evaluation of the uterine mass.

TABULATION, INTEGRATION, AND RESULTS

Sensitivity, specificity, positive and negative likelihood ratios, diagnostic odds ratio, and area under the curve on summary receiver operating characteristic were calculated for each included study and as pooled estimate, with 95% confidence interval (CI); 972 women (694 with uterine leiomyomas and 278 with uterine sarcomas) were included. Ultrasound showed pooled sensitivity of 0.76 (95% CI, 0.70-0.81), specificity of 0.89 (95% CI, 0.87-0.92), positive and negative likelihood ratios of 6.65 (95% CI, 4.45-9.93) and 0.26 (95% CI, 0.07-1.0) respectively, diagnostic odds ratio of 23.06 (95% CI, 4.56-116.53), and area under the curve of 0.8925.

CONCLUSIONS

Ultrasound seems to have only a moderate diagnostic accuracy in the differential diagnosis between uterine leiomyomas and sarcomas, with a lower sensitivity than specificity.

Not All Bad Comes to Harm: Enhanced Recovery After Surgery for Rectosigmoid Endometriosis

STUDY OBJECTIVE

To assess the impact of implementing an enhanced recovery after surgery (ERAS) protocol on the length of hospitalization in women undergoing laparoscopy for rectosigmoid deep infiltrating endometriosis (DIE).

DESIGN

A retrospective cohort study.

SETTING

An academic referral center for endometriosis and minimally invasive gynecologic surgery.

PATIENTS

Women aged between 18 and 50 years scheduled for laparoscopic excision (shaving, full-thickness anterior wall resection, segmental resection) of rectosigmoid endometriosis between February 2017 and February 2023.

INTERVENTIONS

We divided patients into 2 groups (non-ERAS and ERAS) based on the timing of surgery (before or after March 5, 2020). Starting from this day, restrictions were issued to limit the spread of the coronavirus disease 2019 pandemic, inducing our group to implement an ERAS protocol for patients hospitalized after surgery for posterior DIE.

MEASUREMENTS AND MAIN RESULTS

We included 579 patients in the analysis, 316 (54.6%) in the non-ERAS group and 263 (45.4%) in the ERAS group. In the ERAS group, we observed a shorter length of hospital stay (5.8 ± 3.1 days vs 4.8 ± 2.9 days; p <.001) and lower complications rates (33, 12.5% vs 60, 19.0%; p = .04), despite a decreased frequency of conservative surgical approaches (shaving procedures 121 vs 196; p <.001). Repeated surgery or hospital readmissions owing to postdischarge complications were infrequent, with no significant differences between the 2 groups. The multiple linear regression analysis strengthened our results given the higher prevalence of bowel resection surgeries (both full-thickness anterior wall or segmental), showing that patients managed with a multimodal protocol had an overall reduction of hospital stay by 1.5 days.

CONCLUSION

The implementation of an ERAS program in patients undergoing laparoscopic surgery for DIE is associated with a significant reduction in hospital stay, without an increase in perioperative or postoperative complication rates.

Effects of Pelvic Floor Muscle Physiotherapy on Urinary, Bowel, and Sexual Functions in Women with Deep Infiltrating Endometriosis: A Randomized Controlled Trial

Background and Objectives: Endometriosis is a chronic and recurrent disease defined as the presence and proliferation of endometrial glands and stroma outside the uterine cavity. It affects up to 6-10% of women of reproductive age and can be classified into superficial, ovarian, and deep infiltrating endometriosis (DIE). Deep infiltrating endometriosis can be associated with pain symptoms and pelvic floor muscle hypertone. Moreover, it may be responsible of bowel, urinary, and sexual dysfunctions with impairment of women's quality of life. Few studies have investigated the role of physiotherapy in women with DIE. Here, we aimed first to evaluate the effects of pelvic floor physiotherapy (PFP) on urinary, bowel, and sexual functions. Secondly, we aimed to evaluate the effects of ultrasound visual feedback during PFP on pelvic floor and subjective modifications in the frequency of sexual intercourse. Materials and Methods: This randomized controlled trial was conducted between June 2018 and December 2019 at our tertiary center. Nulliparous women with DIE and superficial dyspareunia were enrolled. At first examination, levator hiatal area (LHA) assessed with 3D/4D transperineal ultrasound, pain symptoms, urinary, bowel, and sexual functions were evaluated. Then, women were randomly assigned to no intervention (control group) or treatment with five individual sessions of PFP (experimental group), and after four months women underwent a second examination. Urinary, bowel, and sexual functions were assessed with validated questionnaires at first and second examinations. In particular, the Bristol Female Lower Urinary Tract Symptoms questionnaire was used to evaluate urinary symptoms, the Knowles-Eccersley-Scott-Symptom questionnaire to assess the presence of constipation, and the Female Sexual Function Index to investigate sexual function. Study outcomes were the comparisons among groups in terms of differences in actual changes in median of questionnaire scores between first and second examinations. Results: Thirty women (17 in the experimental group and 13 in the control group) completed the study. No significant differences were found between the two groups regarding urinary, bowel, and sexual functions, although women in the experimental group showed a tendency towards an improvement in constipation symptoms. Conclusion: In women with DIE, PFP does not appear to affect urinary, bowel, and sexual functions. Therefore, despite the improvement in superficial dyspareunia, chronic pelvic pain, and PFM relaxation with high treatment satisfaction, women should be informed about the unclear impact of PFP on urinary, bowel, and sexual functions. Larger studies are necessary to further investigate the impact of PFP on these functions.

PGT-M for Premature Ovarian Failure Related to CGG Repeat Expansion of the FMR1 Gene

Primary ovarian failure (POF) is caused by follicle exhaustion and is associated with menstrual irregularities and elevated gonadotropin levels, which lead to infertility before the age of 40 years. The etiology of POI is mostly unknown, but a heterogeneous genetic and familial background can be identified in a subset of cases. Abnormalities in the fragile X mental retardation 1 gene (FMR1) are among the most prevalent monogenic causes of POI. These abnormalities are caused by the expansion of an unstable CGG repeat in the 5' untranslated region of FMR1. Expansions over 200 repeats cause fragile X syndrome (FXS), whereas expansions between 55 and 200 CGG repeats, which are defined as a fragile X premutation, have been associated with premature ovarian failure type 1 (POF1) in heterozygous females. Preimplantation genetic testing for monogenic diseases (PGT-M) can be proposed when the female carries a premutation or a full mutation. In this narrative review, we aim to recapitulate the clinical and molecular features of POF1 and their implications in the context of PGT-M.

Endometriosis in the time of internet: how web navigation affects women with endometriosis

OBJECTIVES

Patients often search for health-related information on the internet allthough this trend may have some benefits, it also has some risks, such as misinformation. The aim of this study is to evaluate how Internet information seeking affect the level of anxiety in patients with endometriosis.

MATERIALS AND METHODS

This prospective observational study was conducted at our outpatient clinic between March 2019 and December 2020. We enrolled We enrolled all patients with a confirmed sonographic diagnosis of endometriosis who had sought information about the disease prior to our visit. We divided them into two groups based on the source of information (Internet only vs multiple sources). Before the visit, we asked women to fill-in validated questionnaires about anxiety, such as the Generalized Anxiety Disorder-7 (GAD) and the Spielberg State Trait Anxiety Inventory (STAI- Y6) and the Endometriosis Health Profile (EHP) - 5. After the visit, the STAI-Y6 was resubmitted to each woman.

RESULTS

We enrolled 200 women who filled-in the questionnaires: 46 reported the Internet as the only source of information, 52 sought information also from medically qualified sources, 74 consulted only healthcare professionals, and 28 resorted to medical journals. Women who used the Internet as their exclusive source of information were younger on average and their STAI-Y6 score after the visit was significantly lower compared to other group (34.1 ± 11.5 vs 42.1 ± 14.7, p = .001). Moreover, the difference between the STAI-Y6 scores before and after our assessment was higher in these women (-18.3 ± 14.7 vs -10.3 ± 16.5, p = .003).

CONCLUSIONS

Women who sought information online were younger, had lower levels of state trait anxiety after our medical evaluation, and a had a greater reduction in anxiety levels after our examination compared to women who consulted other sources to learn more about endometriosis.KEY MESSAGESWomen using only Internet are younger than those who use other sources of information.Women who researched symptoms online showed higher pre-examination anxiety levels.Patients with severe pain symptoms consulted both the internet and professionals.

Molecular Signature of Endometrial Cancer with Coexistent Adenomyosis: A Multicentric Exploratory Analysis

Adenomyosis has been associated with better survival outcomes in women with endometrial cancer. However, although the endometrial cancer patients' risk stratification has been revolutionized by molecular findings, the impact of the molecular signature on the favorable prognosis of endometrial cancer patients with coexistent adenomyosis is unknown. The aim of our study was to compare the prevalence of molecular groups at poor and intermediate prognosis between endometrial cancer patients with and without coexistent adenomyosis. A multicentric, observational, retrospective, cohort study was performed to assess the differences in the prevalence of p53-abnormal expression (p53-abn) and mismatch repair protein-deficient expression (MMR-d) signatures between endometrial cancer patients with and without coexistent adenomyosis. A total of 147 endometrial cancer patients were included in the study: 38 in the adenomyosis group and 109 in the no adenomyosis group. A total of 37 patients showed the MMR-d signature (12 in the adenomyosis group and 25 in the no adenomyosis group), while 12 showed the p53-abn signature (3 in the adenomyosis group and 9 in the no adenomyosis group). No significant difference was found in the prevalence of p53-abn (p = 1.000) and MMR-d (p = 0.2880) signatures between endometrial cancer patients with and without coexistent adenomyosis. In conclusion, the molecular signature does not appear to explain the better prognosis associated with coexistent adenomyosis in endometrial cancer patients. Further investigation of these findings is necessary through future larger studies.

Dienogest alone or dienogest combined with estrogens in the treatment of ovarian endometriomas, that is the question. A retrospective cohort study

PURPOSE

to compare the effects of Dienogest 2 mg (D) alone or combined with estrogens (D + ethinylestradiol 0.03 mg, D + EE; D + estradiol valerate 1-3 mg, D + EV) in terms of symptoms and endometriotic lesions variations.

METHODS

This retrospective study included symptomatic patients in reproductive age with ultrasound diagnosis of ovarian endometriomas. Medical therapy for at least 12 months with D, D + EE or D + EV was required. Women were evaluated at baseline visit (V1) and after 6 (V2) and 12 months (V3) of therapy.

RESULTS

297 patients were enrolled (156 in the D group, 58 in the D + EE group, 83 in the D + EV group). Medical treatment leaded to a significant reduction in size of endometriomas after 12 months, with no differences between the three groups. When comparing D and D + EE/D + EV groups, a significant decrease of dysmenorrhea was detected in the D group than in D + EE/D + EV group. Conversely, the reduction of dysuria was more significative in the D + EE/D + EV groups rather than in the D group. Regarding tolerability, treatment associated side effects were reported by 16.2% patients. The most frequent one was uterine bleeding/spotting, significantly higher in the D + EV group.

CONCLUSION

Dienogest alone or associated with estrogens (EE/EV) seems to be equally effective in reducing endometriotic lesions mean diameter. The reduction of dysmenorrhea was more significative when D was administered alone, while dysuria seems to improve more when D is associated with estrogens.

Race and ethnicity reporting in endometrial cancer literature

OBJECTIVES

There is evidence that there are differences in survival outcomes among patients with endometrial cancer of different ethnic groups. We aimed to assess the quantity and quality of race/ethnicity reporting in the literature on endometrial cancer published from January 2020 to December 2020.

METHODS

In this systematic review, electronic searches of PubMed, MEDLINE, Web of Sciences, Scopus, and Cochrane Library databases were performed for all articles published in 2020. A total of 3330 articles were reviewed, of which 949 (35%) peer-reviewed human-based articles focusing on endometrial cancer were included. Non-research-focused articles, review articles, meta-analyses, case reports, and non-human studies were excluded. We analyzed the proportion of studies reporting race/ethnicity and assessed the quality of reporting with regard to the adherence to the International Committee of Medical Journal Editors (ICMJE) recommendations. We evaluated the influence of study characteristics on race/ethnicity reporting and compared articles published in journals which adhere to the ICMJE recommendations against those that did not explicitly state that they did.

RESULTS

Of the 949 (28.5%) included articles, 166 (17.5%) reported race/ethnicity of patients, with low quality of reporting. The reporting rate of race/ethnicity was similar when comparing articles from ICMJE and non-ICMJE journals (62 (20.4%) vs 104 (16.1%); p=0.11), prospective versus retrospective studies (53 (22.7%) vs 113 (15.8%); p=0.02), and national versus international studies (147 (17.5%) vs 19 (17.4%); p=0.99). Studies performed in the WHO region of Americas were significantly more consistent in reporting race compared with other regions (119 (44.7%) vs 23 (6.8%) European, 2 (7.4%) Eastern Mediterranean, 21 (7.1%) Western Pacific, 0 (0%) South-East Asia; p<0.001). Female corresponding authors were significantly more consistent in reporting race than male authors (94 (22.5%) vs 72 (13.6%); p<0.001).

CONCLUSIONS

Human-based articles focusing on endometrial cancer have a low frequency and quality of race/ethnicity reporting, even in journals claiming to follow ICMJE recommendations.

How to Manage Endometriosis in Adolescence: The Endometriosis Treatment Italian Club Approach

The evaluation of endometriosis in an adolescent girl is a challenging topic. The initial stage of the disease and the limited diagnostic instrument appropriate for the youth age and for its typical features can reduce the ability of the gynecologist. At the same time, missing a prompt diagnosis can delay the beginning of specific and punctual management of endometriosis, which could avoid a postponed diagnosis from 6 to 12 years, typical of adolescent girls complaining of dysmenorrhea. This article aimed to answer all the potential questions around the diagnosis and management of endometriosis in adolescents starting from a clinical case looking at the possible solution that is easily reproducible in the clinical practice.

The COVID-19 Pandemic Impact on the Psychophysical Health of Post-Menopausal Women: A Cross-Sectional Study

Background and Objectives: The aim of this study was to investigate lifestyle, menopausal symptoms, depression, post-traumatic stress disorder (PTSD) and sleep disorders in post-menopausal women throughout the first wave of the COVID-19 pandemic, including the impact of menopause hormonal therapy (HT). Materials and Methods: Post-menopausal women were given the following questionnaires: socio-demographic characteristics; lifestyle; history of COVID-19; menopause-specific quality of life (MENQOL), the first part of which refers to the pre-pandemic period ("pre COVID-19") and the second refers to the current period ("during COVID-19"); Beck's depression inventory (BDI); the impact of event scale-revised (IES-R); and the Pittsburgh sleep quality index (PSQI). Results: One hundred and twenty-six women completed all questionnaires, with a mean age of 55.5 ± 6.0 years. The mean menopause duration was 5.7 ± 5.6 years. Twenty-four women were taking HT. A significant mean weight gain, a reduction in physical activity (respectively p < 0.001) and worsened quality of romantic relationships (p = 0.001) were reported during the pandemic. Menopausal symptoms did not vary significantly throughout the pandemic; however, women taking menopausal HT had lower physical (p = 0.003) and sexual (p = 0.049) MENQOL domain scores, lower depressive symptoms (p = 0.039) and better romantic relationships (p = 0.008). Conclusions: The COVID-19 pandemic caused reduced physical activity, worsened food habits and weight gain in post-menopausal women. They also reported a high rate of severe-moderate PTSD and a negative influence on their romantic relationships. Menopausal HT seems to be a potential protective factor for sexual and physical status and for symptoms of depression.

Uterine Artery Embolization for the Treatment of Symptomatic Uterine Fibroids of Different Sizes: A Single Center Experience

The present study aimed to evaluate the clinical and radiological 1-year outcomes of uterine artery embolization (UAE) performed in a selected population of women with symptomatic myomas and who do not wish to conceive. Between January 2004 and January 2018, a total of 62 patients with pre-menopausal status and with no wish to conceive in the future underwent UAE for the treatment of symptomatic fibroids. All the patients underwent magnetic resonance imaging (MRI) and/or transvaginal ultrasonography (TV-US) before and after the procedure at 1-year follow-up. Clinical and radiological parameters were recorded, stratifying the population into 3 groups according to the size of the dominant myoma (group 1: <50 mm; group 2: ≥50 and ≤80 mm; group 3: >80 mm). Mean fibroid diameter was significantly reduced (42.6% ± 21.6%) at 1-year follow-up, with excellent improvements in terms of both symptoms and quality of life. No significant difference was observed regarding baseline dimension and the number of myomas. No major complications were reported (2.5%). The present study confirms the safety and efficacy of UAE in the treatment of symptomatic fibroids in pre-menopausal women with no desire to conceive.

Corded and hyalinized endometrioid carcinoma: Summary of clinical, histological, immunohistochemical and molecular data

Corded and hyalinized endometrioid carcinoma (CHEC) represents a potential pitfall for pathologists. This study aimed to provide a complete overview of all clinicopathological and molecular features of CHEC. Electronic databases were searched for all published series of CHEC. Clinical, histological, immunohistochemical and molecular data about CHEC were extracted and pooled. Six studies with 62 patients were identified; mean age was 49.8 years (range 19-83). Most cases showed FIGO stage I (68%), low grade (87.5%), and a favorable outcome (78.4%), with "no specific molecular profile" (NSMP). A subset of cases showed high-grade features (12.5%), p53 abnormalities (11.1%) or mismatch repair (MMR) deficiency (20%) and occurred at an older age (mean age>60 years). Common features of CHEC were: superficial localization of the corded component (88.6%), squamous/morular differentiation (82.5%), nuclear β-catenin accumulation (92%), partial/total loss of CKAE1/AE3 (88.9%), estrogen receptor (95.7%) and e-cadherin (100%), stromal changes such as myxoid (38.5%), osteoid (24%) and chondroid (4.5%), CTNNB1 mutations (57.9%), and POLE-wild-type (100%); 24.4% of cases showed lymphovascular space invasion. A minority of cases (16.2%) showed poor outcome despite a low-grade, NSMP phenotype; the molecular basis for the aggressiveness of these cases is still undefined. Further studies are necessary in this field.

Effect of ospemifene on vaginal microbiome in postmenopausal women with vulvovaginal atrophy

OBJECTIVES

This study aimed (i) to compare the vaginal microbiome profiles of women suffering from vulvovaginal atrophy with that of healthy postmenopausal women and to (ii) assess the effect of ospemifene and systemic hormone treatment on the composition of the vaginal microbiome.

METHODS

Sixty-seven postmenopausal women attending the Gynecology Clinic of Azienda Ospedaliero-Universitaria of Bologna (Italy) were enrolled. Of them, 39 received a diagnosis of atrophy and 28 were considered healthy controls. In the group of atrophic women, 20 were prescribed ospemifene and 19 received hormone treatment. The vaginal health index was calculated, and a vaginal swab was collected for the assessment of vaginal maturation index and the analysis of vaginal microbiome through 16S rRNA gene sequencing. Clinical/microbiological analyses were repeated after 3 months of treatment.

RESULTS

The vaginal microbiome of atrophic women was characterized by a significant reduction of Lactobacillus ( P = 0.002) and an increase of Streptococcus ( P = 0.008) and Sneathia ( P = 0.02). A positive correlation between vaginal health index/vaginal maturation index and Lactobacillus abundance was found ( P = 0.002 and P = 0.035, respectively). Both therapeutic approaches effectively improved vaginal indices. Systemic hormone treatment induced changes in minority bacterial groups of the vaginal microbiome, whereas ospemifene was able to eliminate specific bacterial taxa, such as Staphylococcus ( P = 0.04) and Clostridium ( P = 0.01). Both treatments induced a trend in the increase of bifidobacteria.

CONCLUSIONS

The vaginal microbiome of atrophic women differs significantly from that of healthy postmenopausal women. Ospemifene may lead to a condition of vaginal health, likely characterized by the reduction of "potentially harmful" bacteria.

Predictive factors of sentinel lymph node failed mapping in endometrial carcinoma patients: a systematic review and meta-analysis

OBJECTIVE

In endometrial carcinoma patients, sentinel lymph node bilateral mapping fails in 20-25% of cases, with several factors affecting the likelihood of detection. However, pooled data about predictive factors of failure are lacking. The aim of this systematic review and meta-analysis was to assess the predictive factors of sentinel lymph node failed mapping in endometrial cancer patients undergoing sentinel lymph node biopsy.

METHODS

A systematic review and a meta-analysis was performed searching all studies assessing predictive factors of sentinel lymph node failed mapping in apparent uterine-confined endometrial cancer patients undergoing sentinel lymph node biopsy through the cervical injection of indocyanine green. The associations between sentinel lymph node failed mapping and predictive factors of failure were assessed, calculating the odds ratio (OR) with 95% confidence intervals.

RESULTS

Six studies with a total of 1345 patients were included. Compared with patients with sentinel lymph node bilateral successful mapping, patients with sentinel lymph node failed mapping showed: OR 1.39 (p=0.41) for body mass index >30 kg/m²; OR 1.72 (p=0.24) for menopausal status; OR 1.19 (p=0.74) for adenomyosis; OR 0.86 (p=0.55) for prior pelvic surgery; OR 2.38 (p=0.26) for prior cervical surgery; OR 0.96 (p=0.89) for prior Cesarean section; OR 1.39 (p=0.70) for lysis of adhesions during surgery before sentinel lymph node biopsy; OR 1.77 (p=0.02) for indocyanine green dose <3 mL; OR 1.28 (p=0.31) for deep myometrial invasion; OR 1.21 (p=0.42) for International Federation of Gynecology and Obstetrics (FIGO) grade 3; OR 1.89 (p=0.01) for FIGO stages III-IV; OR 1.62 (p=0.07) for non-endometrioid histotype; OR 1.29 (p=0.25) for lymph-vascular space invasion; OR 4.11 (p<0.0001) for enlarged lymph nodes; and OR 1.71 (p=0.022) for lymph node involvement.

CONCLUSION

Indocyanine green dose <3 mL, FIGO stage III-IV, enlarged lymph nodes, and lymph node involvement are predictive factors of sentinel lymph node failed mapping in endometrial cancer patients.

Surgical Outcomes and Complications of Laparoscopic Hysterectomy for Endometriosis: a multicentric cohort study

STUDY OBJECTIVE

To investigate the postoperative morbidity of laparoscopic hysterectomy (LH) for endometriosis/adenomyosis in terms of operative outcomes and complications.

DESIGN

Retrospective multicentric cohort study.

SETTING

Eight European minimally invasive referral centers.

PATIENTS

Data from 995 patients with pathologically confirmed endometriosis and/or adenomyosis who underwent LH without concomitant urological and/or gastroenterological procedures from January 2010 to December 2020.

INTERVENTIONS

Total laparoscopic hysterectomy.

MEASUREMENTS AND MAIN RESULTS

Demographic patients' characteristics, surgical outcomes, and intraoperative and postoperative complications were evaluated. We considered major postoperative surgical-related complications any grade 2 or more events (Clavien-Dindo score) that occurred within 30 days from surgery. Univariate analysis and multivariable models fit with logistic regression were used to estimate the adjusted odds ratio (OR) and corresponding 95% CI for major complications. Median age at surgery was 44 years (28-54) and about half of them (505, 50.7%) were on medical treatment (estro-progestins, progestin or GnRh-analogues) at the time of surgery. In association with LH, posterior adhesiolysis was performed in 387 (38,9%) cases and deep nodule resection in 302 (30,0%). Intraoperative complications occurred in 3% of the patients and major postoperative complications were registered in 93 (9.3%). The multivariable analysis showed an inverse correlation between the occurrence of Clavien-Dindo >2 complications and age (OR 0.94, 95%CI 0.90-0.99), while previous surgery for endometriosis (OR 1.62, 95%CI 1.01-2.60) and intraoperative complications (OR 6.49, 95%CI 2.65-16.87) were found as predictors of major events. Medical treatment at the time of surgery has emerged as a protective factor (OR 0.50, 95%CI 0.31-0.81).

CONCLUSION

LH for endometriosis/adenomyosis is associated with non-negligible morbidity. Knowing the factors associated with higher risks of complications might be used for risk stratification and could help clinicians during preoperative counseling. The administration of estro-progestin or progesterone preoperatively might reduce the risks of postoperative complications following surgery.
