RESUMO

Background: Uterine sarcomas (US) are rare cancer of possible occurrence even in women of childbearing age. To date, total hysterectomy is the standard treatment in the early stages. The possibilities of carrying out fertility-sparing treatments (FST) to save the fertility of women with unfulfilled reproductive desires are described in the literature, but to date, they can only be considered experimental. Objective: The aim of this systematic review was to evaluate the oncological and reproductive outcomes of women with different histological types of US undergoing FST. Design: Systematic review. Data sources and methods: Electronic databases were searched for English-language studies describing FST for US until January 31, 2024. Results: Forty-five papers which met the abovementioned inclusion criteria, were included in the qualitative analysis. Quantitative analysis was not possible because of the heterogeneity of the data. A descriptive summary of the results according to the histotype of US was provided. Six hundred forty-one patients of childbearing age with US and undergoing FST. After treatment with FST, 89 (13.9%) disease recurrences and 107 (16.7%) pregnancies were recorded. Conclusion: In selected cases of early-stage US, FST may be proposed. However, the patient must be informed of the real possibility of recurrence and potentially difficult achievement of pregnancy. Additional well-designed prospective studies and clinical trials are needed to address the knowledge gaps and enhance clinical decision-making in this population. Trial registration: PROSPERO ID: CRD42024509356.

RESUMO

INTRODUCTION: Hysteroscopy is a critical procedure in gynecology for diagnosing and managing intrauterine pathology. Traditional hands-on training faces ethical and safety challenges, leading to an increased reliance on simulation training. This review systematically assesses the effectiveness of hysteroscopic simulation training in enhancing the technical skills of obstetrics and gynecology residents and medical students. METHODS: A PRISMA-guided literature search was conducted, covering English-language articles from January 2000 to December 2023. Studies were selected based on pre-defined criteria, focusing on the impact of simulation training on the targeted educational group. Metrics for evaluating skill improvement included machine-recorded metrics, Objective Structured Assessment of Technical Skills (OSATS), and global rating scales. RESULTS: The review included nine studies with varied designs, demonstrating significant improvements in hysteroscopic skills following simulation training. Virtual reality (VR) simulators showed substantial benefits in skill acquisition, while physical simulators provided valuable tactile feedback. However, long-term skill retention and the impact on non-technical skills were not adequately assessed. CONCLUSIONS: Simulation-based training effectively enhances hysteroscopic skills in medical students and residents. Further research is needed to explore long-term skill retention and the development of non-technical competencies. Robust studies, including randomized trials, are required for definitive validation.

RESUMO

Ovarian cancer affects thousands of women every year and represents the female cancer with the highest mortality rate. Effectively, it is a severe disease that requires a multidisciplinary approach for optimal treatment. Surgery currently is the cornerstone of its treatment and numerous methods have been analyzed and developed to predict the possibility of obtaining a residual tumor of 0 (RT=0). This review aimed to analyze the available data in the literature about minimally invasive surgical methods to predict an RT=0 in patients with advanced epithelial ovarian carcinoma undergoing primary debulking surgery. An accurate review of the literature has been performed on the available data about the surgical criteria of cytoreducibility during primary debulking surgery. An accurate assessment of the extent of intra- and extra-abdominal pathology is essential to guide the surgeon in the most appropriate therapeutic choice for patients with ovarian cancer and multidisciplinary approaches that combine different methodologies such as radiological methods (magnetic resonance imaging, positron emission tomography and computed tomography), surgical (mini-laparotomy, laparoscopy) and serological (CA-125, HE4) data provide a complete picture in determining the extent of the tumor and an enormous aid in personalizing the therapeutic approach.

RESUMO

OBJECTIVE: This study aimed to assess the efficacy of randomly started oral dienogest/ethinylestradiol (DNG/EE) for swift endometrial preparation prior to outpatient hysteroscopic polypectomy in perimenopausal women. METHOD: A multicenter, prospective, randomized controlled trial was conducted in university hospitals. Eighty perimenopausal women scheduled for outpatient hysteroscopic polypectomy between January 2023 and March 2024 were randomly assigned to either intervention (n = 40) or control (n = 40) groups. Exclusion criteria included concomitant endometrial pathologies, recent therapy and adnexal diseases. The intervention group received oral DNG/EE 2 mg/0.03 mg/day started on any day of the menstrual cycle for 14 days. The control group underwent polypectomy between menstrual cycle days 8 and 11 without pharmacological treatment. RESULTS: Pre-procedure (p < 0.001) and post-procedure (p < 0.001) endometrial thickness were significantly reduced in the intervention group, along with a higher incidence of hypotrophic/atrophic endometrial patterns (p < 0.001). Surgical parameters also differed significantly between groups. CONCLUSION: DNG/EE treatment offers rapid, cost-effective endometrial preparation, enhancing surgical outcomes and patient satisfaction during outpatient polypectomy. TRIAL REGISTRATION: ClinicalTrials.gov NCT06316206.

RESUMO

BACKGROUND: Hysterectomy for endometrial hyperplasia and endometrial cancer in morbidly obese patients is challenging. Here, we reported data regarding three minimally invasive approaches. METHOD: This is a multicenter retrospective study evaluating 30-day and 90-day surgery-related outcomes of morbidly obese patients (those with BMI > 40kg/m2) undergoing robotic-assisted, laparoscopic, and vaginal hysterectomy. RESULTS: Charts of 95 morbidly obese patients who underwent surgery for endometrial cancer were retrieved. Overall, robotic-assisted, laparoscopic, and vaginal surgeries were performed in 35 (36.8%), 38 (40%), and 22 (23.2%) patients, respectively. Patients having robotic-assisted surgery experienced longer operative time than patients having vaginal and laparoscopic approaches (p < 0.001). Surgical approaches did not influence the risk of having intraoperative and severe (Clavien-Dindo grade 3 or more) postoperative complications. No 90-day mortality occurred. CONCLUSIONS: Robotic-assisted, laparoscopic, and vaginal surgery represent three safe and feasible minimally invasive approaches to manage morbidly obese patients with endometrial hyperplasia and endometrial cancer.

RESUMO

The menopause transition is an important period in a woman's life, during which she is at an increased risk of mood disorders. Estrogen and progesterone fluctuations during the menopausal transition and very low levels of estradiol after menopause have a profound effect on the central nervous system (CNS), causing an imbalance between excitatory and inhibitory inputs. Changes in neurotransmission and neuronal interactions that occur with estradiol withdrawal disrupt the normal neurological balance and may be associated with menopausal symptoms. Hot flushes, depressed mood and anxiety are all symptoms of menopause that are a consequence of the complex changes that occur in the CNS, involving many signaling pathways and neurotransmitters (i.e. γ-aminobutyric acid, serotonin, dopamine), neurosteroids (i.e. allopregnanolone), and neuropeptides (i.e. kisspeptin, neurokinin B). All these pathways are closely linked, and the complex interactions that exist are not yet fully understood. This review summarizes the neuroendocrine changes in the CNS during the menopausal transition, with particular emphasis on those that underlie mood changes.

RESUMO

Hysteroscopy has truly revolutionized the field of diagnostic and operative gynecology. It is presently regarded as the gold standard method for both the diagnosis and treatment of intrauterine diseases and it has fundamentally altered the way gynecologists treat patients with such conditions. These pathologies can now be diagnosed and treated in an outpatient setting, thanks to technological advancements and instrument downsizing. Two hundred years of development and notable innovation are now reflected in the present hysteroscopic practice. This review attempts to trace the boundaries-pushing history of hysteroscopy by highlighting the advancements in technology and the therapeutic and diagnostic benefits offered by this groundbreaking approach.

RESUMO

Background and Objectives: Cervical cancer (CC) represents a significant health concern worldwide, particularly for younger women. Cold knife (CK) conization and carbon dioxide (CO2) laser conization are two techniques commonly used to remove pre-invasive lesions, offering a potential curative intent in cases of incidental diagnosis of CC. This study aimed to assess the clinical implications and pathological outcomes of CK vs. CO2 laser conization for pre-invasive lesions. Materials and Methods: We retrospectively analyzed women who underwent CO2 or CK conization for high-grade preinvasive lesions (CIN2/3, CIS and AIS) between 2010 and 2022. Patient demographics, surgical details and pathological outcomes were collected. Pregnancy outcomes, including composite adverse obstetric rates, and oncological follow-up data, were also obtained. Results: In all, 1270 women were included; of them, 1225 (96.5%) underwent CO2, and 45 (3.5%) underwent CK conization. Overall, the rate of positive endocervical or deep margins was lower with CO2 laser compared to CK (4.3% vs. 13.3%, p = 0.015). Incidental CC was diagnosed in 56 (4.4%) patients, with 35 (62.5%) squamous and 21 (46.6%) adenocarcinomas. In a multivariate regression model, the relative risk for positive endocervical or deep margins is significantly greater in cases of incidental diagnosis of CC (p < 0.01). In cases of incidental diagnosis of CC, we found that the probabilities of having either positive endocervical or deep margins after CO2 laser or CK conization are similar, with a higher risk in case of adenocarcinoma lesion. Among women with CC, 42 (75%) opted for radical treatment, while 14 (25%) underwent a follow-up. Only one woman (7.1%) in the follow-up group, who had undergone CK conization, experienced a composite adverse obstetric outcome. No recurrences were observed after a median follow-up of 53 months. Conclusions: CO2 laser conization achieved a lower positive margin rate overall. CK and CO2 conization appear to be equivalent oncological options for incidental CC.

RESUMO

BACKGROUND: Hereditary breast and ovarian cancer syndrome (HBOC) predisposes women to an increased risk mainly of breast and tubo-ovarian cancer. The aim of the study is to investigate whether being diagnosed with HBOC syndrome is itself a risk factor for sexual dysfunction. METHODS: An ad hoc questionnaire, including baseline demographic and clinical data, and the Sexual Function Questionnaire 28 (SFQ28) were administered to HBOC female carriers (study group) and to a control group. RESULTS: After propensity score matching (1:1), we enrolled 202 women, 101 in the study group and 101 in the control group. In a multivariate analysis, we finally found that menopausal status was the only risk factor for a significant low score in the domains Desire (HR 0.66; CI95% 0.47-0.93; p = 0.017), Arousal (Lubrication) (HR 0.52; CI95% 0.34-0.80; p = 0.003), Arousal (Cognitive) (HR 0.64; CI95% 0.44-0.95; p = 0.027), and Orgasm (HR 0.33; CI95% (0.16-0.70; p = 0.004), independent of risk-reducing surgery for gynecological malignancy. Psycho-oncology support is a protective factor for the Enjoyment domain (HR 1.38; CI95% 1.05-1.81; p = 0.022). CONCLUSIONS: HBOC syndrome itself does not affect SFQ28 domains, while menopausal status significantly influences sexual health, with potential mitigating effects of psycho-oncological support.

RESUMO

BACKGROUND AND OBJECTIVE: Pelvic organ prolapse (POP) affects 40% of women, with a 12%-19% lifetime surgical risk. Italy showed high practice variation in POP surgery, possibly impacting equity of access to healthcare services, a central goal of Beveridge-like health systems. According to the literature, unwarranted variation, influenced by physician attitudes or resource allocation, must be reduced. We aimed to identify determinants influencing women's choice when asked whether they prefer surgical or conservative POP management. DESIGN, SETTING AND POPULATION: In this nationwide prospective study, we distributed a Qualtrics questionnaire via social media to any Italian women over 18 years old who voluntarily decided to participate in the survey. INTERVENTION: A grade 3 POP scenario was presented. Women were asked how likely they would have surgery. Each woman randomly received only 1 question out of 11: 1 question was the reference question ('How likely would you have surgery?') while 10 questions contained a potential determinant influencing woman's choice ('How likely would you have surgery if…?'). OUTCOME: The outcome was the chance of choosing surgery expressed as a percentage. We analysed the effect of each factor on the outcome by using adjusted beta regression models. RESULTS: Respondents (n=222) opted for surgery with a median probability of 61.5%. Factors significantly increasing the chance of choosing surgery were advice from physicians, the presence of a trusted physician during hospitalisation, surgical approach with low complication rates, uterine-sparing surgery, the absence of postoperative abdominal scars and nearby hospital. CONCLUSIONS: Our findings provide health managers and policy-makers with new evidence to better understand women's decision-making and partly capture the determinants of unwarranted variation. These inputs may also be used as attributes for a future discrete choice experiment.

RESUMO

Cosmetic and functional gynecology have gained popularity among patients, but the scientific literature in this field, particularly regarding the cosmetic aspect, is lacking. The use of evidence-based medicine is crucial to validate diagnostic tools and treatment protocols. However, the advent of artificial intelligence (AI) offers a promising solution to address this issue. ChatGPT, a sophisticated language model, can revolutionize AI in medicine, enabling accurate diagnosis, personalized treatment plans, and expedited research analysis. Cosmetic and functional gynecology can leverage AI to develop the field and improve evidence gathering. AI can aid in precise and personalized diagnosis, implement standardized assessment tools, simulate treatment outcomes, and assess under-skin anatomy through virtual reality. AI tools can assist clinicians in diagnosing and comparing difficult cases, calculate treatment risks, and contribute to standardization by collecting global evidence and generating guidelines. The use of AI in cosmetic and functional gynecology holds significant potential to advance the field and improve patient outcomes. This novel combination of AI and gynecology represents a groundbreaking development in medicine, emphasizing the importance of appropriate and correct AI usage.

RESUMO

OBJECTIVE: To assess if the use of a V-Y reconstructive flap after excisional radical surgery positively influences the surgical outcomes in patients with vulvar cancer. METHODS: This was a multicenter, retrospective, controlled study. Surgical outcomes and complication rates of women with invasive vulvar cancer who underwent radical surgery and vulvar reconstruction and those who underwent radical surgery without the reconstruction step were compared. Only patients who underwent bilateral or unilateral V-Y advancement fascio-cutaneous flaps were included in the reconstruction group. Univariate and multivariate logistic regression models were used to analyze predicting variables for their association with complication rates. RESULTS: Overall, 361 patients were included: 190 (52%) underwent the reconstructive step after the excisional radical procedure and were compared with 171 (47.4%) who did not undergo the reconstructive step. At multivariate analysis, body mass index >30 kg/m2 (odds ratio (OR) 3.36, p=0.007) and diabetes (OR 2.62, p<0.022) were independently correlated with wound infection. Moreover, increasing age (OR 1.52, p=0.009), body mass index >30 kg/m2 (OR 3.21, p=0.002,) and International Federation of Gynecology and Obstetrics (FIGO) stages III-IV (OR 2.25, p=0.017) were independent predictors of wound dehiscence. A significant reduction in the incidence of postoperative wound complications among patients who underwent V-Y reconstructive flaps was demonstrated. This was correlated more significantly in women with lesions >4 cm. CONCLUSIONS: The adoption of V-Y flaps in vulvar surgery was correlated with reduced surgical related complications, particularly in vulnerable patients involving large surgical defects following excisional radical procedures.

RESUMO

INTRODUCTION: This Special Report aims to highlight the importance of tailored therapies in women with Polycystic Ovary Syndrome (PCOS), avoiding prescribing generalized or unsuitable therapies based on oral contraceptive pills (OCPs). AREAS COVERED: This article discusses the benefits and risks of OCP-based therapy, highlighting the possible undesirable effects, especially in those patients exhibiting risk factors as women with PCOS, and the importance of carefully evaluated tailored therapeutic approaches. Literature searches were performed with the use of PubMed, Google Scholar, and Web of Science between January and February 2024. EXPERT OPINION: Considering the recent re-analysis of PCOS Rotterdam Criteria by the Expert Group on Inositol in Basic and Clinical Research, and on PCOS (EGOI-PCOS), the traditional Rotterdam phenotypes can be reclassified to achieve more efficacious therapy choices. Using personalized therapies that consider the specific clinical characteristics of the patient allows to improve the management of the syndrome, thus avoiding the generalized use of OCPs, which risk treating only symptoms of PCOS rather than the underlying cause. In cases when contraceptive purpose is desired, patients may benefit from combined therapy with diet or insulin-sensitizer agents, as inositol, to rebalance the metabolic profile, thus reducing the risk of developing future complications.

RESUMO

OBJECTIVE: To evaluate the use of oral nomegestrol acetate/estradiol in random start rapid preparation of endometrium before office hysteroscopic polypectomy. STUDY DESIGN: Multicenter, prospective, randomized controlled trial. SETTING: University hospitals. PARTICIPANTS: 80 adult women undergoing office hysteroscopic polypectomy between January 2023 and March 2024 were randomized to intervention (n = 40) or control (n = 40). Exclusion criteria included the presence of endouterine pathology other than endometrial polyps solely. METHODS: Subjects in the intervention group were treated with oral nomegestrol acetate/estradiol 1.5 mg/2.5 mg/day started taking the drug from an indefinite time in the menstrual cycle (random start) for 14 days. Subjects in the control group did not receive any pharmaceutical treatment and underwent polypectomy between days 8 and 11 of the menstrual cycle. RESULTS: On the day of the procedure, the difference in pre- and post-office hysteroscopic polypectomy endometrial ultrasound thickness was statistically significant between the two groups, with endometrial thickness in both measurements being thinner for the intervention group (p < 0.001). In the nomegestrol acetate/estradiol-treated group, compared with the control, there was also a statistically significant difference in the physician's assessment of the quality of endometrial preparation (p < 0.001), the quality of visualization of the uterine cavity (p < 0.001), and satisfaction with the performance of the procedure (p < 0.001). Finally, all surgical outcomes analyzed were better in the treatment group. CONCLUSION: Treatment with nomegestrol acetate/estradiol could provide rapid, satisfactory and low-cost preparation of the endometrium before office polypectomy, thus improving surgical performance and woman's compliance. TRIAL REGISTRATION: ClinicalTrials.gov NCT06316219.

RESUMO

INTRODUCTION AND HYPOTHESIS: Lateral suspension is an abdominal prosthetic surgical procedure used to correct apical prolapse. The procedure involves the placement of a T-shaped mesh on the anterior vaginal wall and on the isthmus or uterine cervix that is suspended laterally and posteriorly to the abdominal wall. Since its description in the late 90s, modifications of the technique have been described. So far, no consensus on the correct indications, safety, advantages, and disadvantages of this emerging procedure has been reached. METHODS: A modified Delphi process was used to build consensus within a group of 21 international surgeons who are experts in the performance of laparoscopic lateral suspension (LLS). The process was held with a first online round, where the experts expressed their level of agreement on 64 statements on indications, technical features, and other aspects of LLS. A subsequent re-discussion of statements where a threshold of agreement was not reached was held in presence. RESULTS: The Delphi process allowed the identification of several aspects of LLS that represented areas of agreement by the experts. The experts agreed that LLS is a safe and effective technique to correct apical and anterior prolapse. The experts highlighted several key technical aspects of the procedure, including clinical indications and surgical steps. CONCLUSIONS: This Delphi consensus provides valuable guidance and criteria for the use of LLS in the treatment of pelvic organ prolapse, based on expert opinion by large volume surgeons' experts in the performance of this innovative procedure.

RESUMO

Endometriosis is characterized by the growth of endometrial-like tissue outside the uterus, and it is associated with alterations in the expression of hormone receptors and inflammation. Estetrol (E4) is a weak estrogen that recently has been approved for contraception. We evaluated the effect of E4 on the growth of endometriotic-like lesions and the expression of TNF-α, estrogen receptors (ERs), and progesterone receptors (PRs) in an in vivo murine model. Endometriosis was induced surgically in female C57BL/6 mice. E4 was delivered via Alzet pump (3 mg/kg/day) from the 15th postoperative day for 4 weeks. E4 significantly reduced the volume (p < 0.001) and weight (p < 0.05) of ectopic lesions. Histologically, E4 did not affect cell proliferation (PCNA immunohistochemistry) but it did increase cell apoptosis (TUNEL assay) (p < 0.05). Furthermore, it modulated oxidative stress (SOD, CAT, and GPX activity, p < 0.05) and increased lipid peroxidation (TBARS/MDA, p < 0.01). Molecular analysis showed mRNA (RT-qPCR) and protein (ELISA) expression of TNF-α decreased (p < 0.05) and mRNA expression of Esr2 reduced (p < 0.05), in contrast with the increased expression of Esr1 (p < 0.01) and Pgr (p < 0.05). The present study demonstrates for the first time that E4 limited the development and progression of endometriosis in vivo.

RESUMO

Mutations in genes encoding for proteins along the RAS-RAF-MEK-ERK pathway have been detected in a variety of tumor entities including ovarian carcinomas. In the recent years, several inhibitors of this pathway have been developed, whose antitumor potential is currently being assessed in different clinical trials. Low grade serous ovarian carcinoma, is a rare gynecological tumor which shows favorable overall survival, compared to the general ovarian cancer population, but worrying resistance to conventional chemotherapies. The clinical behavior of low grade serous ovarian carcinoma reflects the different gene profile compared to high-grade serous carcinoma: KRAS/BRAF mutations. BRAF inhibitors as single agents were approved for the treatment of BRAF mutated tumors. Nevertheless, many patients face progressive disease. The understanding of the mechanisms of resistance to BRAF inhibitors therapy and preclinical studies showing that BRAF and mitogen-activated protein kinase kinase (MEK) inhibitors combined therapy delays the onset of resistance compared to BRAF inhibitor single agent, led to the clinical investigation of combined therapy. The aim of this paper is to review the efficacy and safety of the combination of BRAF plus MEK inhibitors on ovarian carcinomas, in particularly focusing on low grade serous ovarian carcinoma.

RESUMO

Myomectomy is one of the most common surgical procedure in the field of gynecology. However, the role of laparoscopic myomectomy is still debated for many factors, including surgical considerations, safety and fertility concerns, long-term outcomes, and cost-related issues. The aim of this study is to evaluate the surgical peri- and post-operative outcomes of laparoscopic and abdominal myomectomy. A systematic search for studies was performed up to June 2023 through MEDLINE, Pubmed, Embase. Studies reporting the comparison of surgical and obstetrical outcomes in laparoscopic versus laparotomic myomectomy were included for the following outcomes: time of surgery, estimated blood loss, decrease of postoperative hemoglobin, hospital stay, intra-operative complication rates, postoperative complications rates, postoperative analgesic use, postoperative pain at 24 h and pregnancy rate. The meta-analysis was performed using the Cochrane Review software. Fifty-six relevant articles were retrieved through the process of evidence acquisition. Eleven articles met inclusion criteria, for a total of 2,133 patients undergoing laparoscopic or laparotomic myomectomy. The estimated blood loss [standard mean differences (SMD) 0.72, IC 95 % 0.22 to 1.22], the hospital stays [SMD 3.12, IC 95 % 0.57 to 4.28], were significantly lower in laparoscopic than in open group. No statistically significant difference in intra-operative and post-operative complication rates, in pregnancy rate and others obstetrical outcomes between two surgical approaches were found. The findings of present metanalysis suggest that laparoscopic myomectomy offers multiple benefits, including reduced blood loss, shorter hospital stays, and less postoperative analgesic need, without a significant increase in complication rates and similar results in obstetrical outcomes when compared to abdominal myomectomy. However, the presence of few randomized studies on selected population may limit the generalizability of the findings to the entire population. Therefore, more well-designed studies or large population programdata to draw definitive conclusions are therefore warranted.
