RESUMO
Epithelial ovarian cancer is a significant global health issue among women. Diagnosis and treatment pose challenges due to difficulties in predicting patient responses to therapy, primarily stemming from gaps in understanding tumor chemoresistance mechanisms. Recent advancements in transcriptomic technologies like single-cell RNA sequencing and spatial transcriptomics have greatly improved our understanding of ovarian cancer intratumor heterogeneity and tumor microenvironment composition. Spatial transcriptomics, in particular, comprises a plethora of technologies that enable the detection of hundreds of transcriptomes and their spatial distribution within a histological section, facilitating the study of cell types, states, and interactions within the tumor and its microenvironment. Studies investigating the spatial distribution of gene expression in ovarian cancer masses have identified specific features that impact prognosis and therapy outcomes. Emerging evidence suggests that specific spatial patterns of tumor cells and their immune and non-immune microenvironment significantly influence therapy response, as well as the behavior and progression of primary tumors and metastatic sites. The importance of spatially contextualizing ovarian cancer transcriptomes is underscored by these findings, which will advance our understanding and therapeutic approaches for this complex disease.
RESUMO
Immunotherapy, particularly the use of immune checkpoint inhibitors (ICIs), has shown limited efficacy in treating ovarian cancer (OC), possibly due to diverse T cell infiltration patterns in the tumor microenvironment. This review explores how neoadjuvant chemotherapy (NACT) impacts the immune landscape of OC, focusing on tumor-infiltrating lymphocytes (TILs), PD-1/PD-L1 expression, and their clinical implications. A comprehensive literature search across four databases yielded nine relevant studies. These studies evaluated stromal (sTILs) and intra-epithelial (ieTILs) TILs before and after NACT. sTIL responses varied, impacting prognostic outcomes, and ieTILs increased in some patients without clear survival associations. PD-L1 expression after NACT correlated with improved overall survival (OS), and increases in granzyme B+ and PD-1 correlated with longer progression-free survival (PFS). Remarkably, reduced FoxP3+ TILs post-NACT correlated with better prognosis. NACT often increases sTIL/ieTIL and CD8+ subpopulations, but their correlation with improved PFS and OS varies. Upregulation of co-inhibitory molecules, notably PD-L1, suggests an immunosuppressive response to chemotherapy. Ongoing trials exploring neoadjuvant ICIs and chemotherapy offer promise for advancing OC treatment. Standardized measurements assessing TIL density, location, and heterogeneity are crucial for addressing genetic complexity and immunological heterogeneity in OC.

Introduction: Ovarian cancer (OC) exhibits an aggressive behavior, wherein the therapeutic approach always involves both surgery and chemotherapy. Survival outcomes are still related to comprehensive surgical excision of all macroscopic lesions (Rauh-Hain et al., 2017), increasing gynecologic oncologists' efforts to achieve the highest possible complete resection rate (Tozzi et al., 2024). The peritoneum serves as both a dissemination pathway and a barrier that restricts tumor spread beyond its confines. This understanding has prompted the adoption of en-bloc resection strategy for the entire pelvis, involving the removal of pelvic organs along with the surrounding peritoneum. The en-bloc pelvic resection procedure allows for the removal of pelvic disease in all cases of advanced ovarian cancer (Tozzi et al., 2017).Endeavors should be also directed towards minimizing surgical morbidity, by the adoption of minimally invasive surgery for debulking procedures (Tozzi et al., 2023). Case: This video demonstrates a laparoscopic en-bloc pelvic resection with creation of an end-to-end transanal anastomosis. The surgical specimen extraction and the placement of the anvil were performed through the vaginal route.A 75 year-old patient presented with FIGO stage IIIC OC with a 12 cm pelvic mass involving the whole pelvis. The patient was enrolled in the ULTRA-LAP trial and underwent laparoscopic primary debulking surgery with en-bloc pelvic resection. No protective ileostomy was performed and bowel opening occurred on the fifth postoperative day. The patient was discharged on the 11th postoperative day, thereafter completing a regimen of 6 cycles of carboplatin and paclitaxel chemotherapy. Conclusions: The en-bloc resection of the pelvis is a standardized procedure that consists of ten reproducible steps.
RESUMO
Background: The Endometriosis Fertility Index (EFI), is a crucial validated surgical tool used for predicting fertility outcomes in women with endometriosis. This study aims to assess the concordance between a preoperative clinical and instrumental EFI evaluation (uEFI) and the EFI score obtained during an exploratory laparoscopy prior to surgery (sEFI). Methods: This study presents preliminary data from a broader observational cohort study. The Least Function score for the uEFI was calculated using a modified version of the original surgical EFI by incorporating a clinical examination, advanced ultrasound, and hysterosalpingo-foam sonography (HyFoSy). Results: The preoperative estimation of the EFI (uEFI) demonstrated a high concordance (k = 0.695, ρs = 0.811) with the sEFI. Remarkably, the surgical interventions led to a significant improvement in the EFI values, with 80% of the intermediate EFI transitioning to a high level, thereby highlighting the positive impact of surgery on fertility outcomes. Conclusion: This study highlights the accuracy of preoperative EFI estimation (uEFI) and its strong agreement with intraoperative assessment. It underscores the potential of a preoperative management tool to guide the allocation of infertile women with endometriosis to operative laparoscopy, direct assisted reproductive technology (ART), or spontaneous attempts at pregnancy.
RESUMO
OBJECTIVE: To describe the surgical technique, assess feasibility, efficacy, and safety of peritonectomy and/or resection of mesentery (P-Rme) during Visceral-Peritoneal Debulking (VPD) in patients with stage IIIC-IV ovarian cancer (OC). METHODS: In April 2009 we registered a protocol study on the safety and feasibility of P-Rme. In the period April 2009-December 2022, 687 patients with FIGO stage IIIC-IV ovarian cancer underwent VPD. One hundred and twenty-nine patients (18.7%) had extensive disease on the mesentery and underwent P-Rme. Feasibility was assessed as the number of procedures completed. Efficacy was measured as the rate of Complete Resection (CR). Safety was defined by the intra- and post-operative morbidity rate specifically associated with these procedures. RESULTS: In all patients P-Rme was successfully completed. P-me was performed in 82 patients and R-me in 47, both procedures in 23 patients. CR was achieved in all 129 patients with an efficacy of 100%. Intra-operatively 5 patients out of 129 experienced small bowel loop surgical devascularization. They required small bowel resection and anastomosis. The procedure specific morbidity was 3.8%. No post-operative complication was related to P-Rme. At 64 months median follow-up, survival outcomes in the study group were similar to patients in the control group. CONCLUSION: Overall, almost 20% of the VPD patients needed P-Rme to obtain a CR. P-Rme was a safe and effective step during VPD. The rate of CR in the study group was 100% achieved thanks to the addition of the P-Rme. No procedure specific post-operative complications occurred but 3.8% of the patients had unplanned additional surgery related to these procedures.

OBJECTIVE: A non-randomized prospective clinical trial (ULTRA-LAP) was registered to test safety, side effects and efficacy of laparoscopic Visceral-Peritoneal Debulking (L-VPD) in patients with stage III-IV ovarian cancer (OC). A pilot study was designed to identify which OC patients are suitable to undergo L-VPD. METHODS: Between March 2016 and October 2021, all consecutive patients with OC underwent exploratory laparoscopy (EXL). All patients whose disease was deemed amenable for a complete resection (CR) at imaging review and EXL, underwent VPD. In all patients a consistent attempt was made at completing L-VPD. RESULTS: Two hundred and eight OC had EXL in the study period: 121 underwent interval VPD and 87 up-front VPD. Overall, 158 patients had VPD by laparotomy (75.9%) and 50 (24.1%) had L-VPD, of which 34 patients as interval (iL-VPD) and 16 as up-front (uL-VPD). Intra- and post-operative morbidity was very low in the L-VPD group. CR rate was 98% in L-VPD group and 94% in VPD. Most common reason for conversion was diaphragmatic disease extending dorsally. CONCLUSION: In the pilot study of ULTRA-LAP, L-VPD was completed in 24,1% of OC. Initial analysis supports the feasibility of L-VPD in 2 groups of OC: those with no gross disease at interval surgery and those with gross visible disease at upfront or interval surgery, but limited to: pelvis (including recto-sigmoid), gastro colic omentum, peritoneum and diaphragm, the latter not requiring dorsal liver mobilization. Both groups had 100% feasibility and have been thus forth recruited to ULTRA-LAP. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT05862740.

OBJECTIVE: To compare performance of Assessment of Different NEoplasias in the adneXa (ADNEX model), Ovarian-Adnexal Reporting and Data System (O-RADS), Simple Rules Risk (SRR) assessment and the two-step strategy based on the application of Simple Rules (SR) followed by SRR and SR followed by ADNEX in the pre-operative discrimination between benign and malignant adnexal masses (AMs). METHODS: We conducted a retrospective study from January-2018 to December-2021 in which consecutive patients with at AMs were recruited. Accuracy metrics included sensitivity (SE) and specificity (SP) with their 95% confidence intervals (CI) were calculated for ADNEX, O-RADS and SRR. When SR was inconclusive a "two-step strategy" was adopted applying SR + ADNEX model and SR + SRR assessment. RESULTS: A total of 514 women were included, 400 (77.8%) had a benign ovarian tumor and 114 (22.2%) had a malignant tumor. At a threshold malignancy risk of >10%, the SE and SP of ADNEX model, O-RADS and SRR were: 0.92 (95% CI, 0.86-0.96) and 0.88 (95% CI, 0.85-0.91); 0.93 (95% CI, 0.87-0.97) and 0.89 (95% CI, 0.96-0.92); 0.88 (95% CI, 0.80-0.93) and 0.84 (95% CI, 0.80-0.87), respectively. When we applied SR, 109 (21.2%) cases resulted inconclusive. The SE and SP of two-step strategy SR + SRR assessment and SR + ADNEX model were 0.88 (95% CI, 0.80-0.93) and 0.92 (95% CI, 0.89-0.94), SR + ADNEX model 0.90 (95% CI, 0.83-0.95) and 0.93 (95% CI, 0.90-0.96), respectively. CONCLUSIONS: O-RADS presented the highest SE, similar to ADNEX model and SR + ADNEX model. However, the SR + ADNEX model presented the higher performance accuracy with the higher SP and PPV. This two-step strategy, SR and ADNEX model applicated to inconclusive SR, is convenient for clinical evaluation.
RESUMO
OBJECTIVE: To summarize evidence from randomized controlled trials (RCTs) on the effectiveness of virtual reality technology (VRT), as used by patients, for reducing pain during outpatient hysteroscopy. DATA SOURCES: Electronic databases and clinical registers were searched until June 21, 2023. The review protocol was registered in PROSPERO before the data extraction (CRD42023434340). METHODS OF STUDY SELECTION: We included RCTs of patients receiving VRT compared with controls receiving routine care during outpatient hysteroscopy. TABULATION, INTEGRATION, AND RESULTS: The primary outcome was average pain during hysteroscopy. Pooled results were expressed as mean differences (MDs) with 95% confidence interval (CI). Sources of heterogeneity were investigated through sensitivity and subgroups analysis. Five RCTs were included (435 participants). The comparison between the intervention and control groups showed a borderline difference in perceived pain during hysteroscopy (MD -0.88, 95% CI -1.77 to 0.01). Subgroup analysis based on the type of VRT (active or passive) indicated that active VRT potentially reduced the perception of pain (MD -1.42, 95% CI -2.21 to -0.62), whereas passive VRT had no effect (MD -0.06, 95% CI -1.15 to 1.03). CONCLUSION: Patients' use of active VRT may be associated with a reduction in pain during outpatient hysteroscopy (evidence Grading of Recommendations Assessment, Development, and Evaluation 2/4). Future research should focus on conducting methodologically robust studies with larger sample sizes and more homogeneous populations.

Ovarian cancer (OC) has the highest mortality rate of all gynecological malignancies due to the high prevalence of advanced stages of diagnosis and the high rate of recurrence. Furthermore, the heterogeneity of OC tumors contributes to the rapid development of resistance to conventional chemotherapy. In recent years, in order to overcome these problems, targeted therapies have been introduced in various types of tumors, including gynecological cancer. However, the lack of predictive biomarkers showing different clinical benefits limits the effectiveness of these therapies. This requires the development of preclinical models that can replicate the histological and molecular characteristics of OC subtypes. In this scenario, organoids become an important preclinical model for personalized medicine. In fact, patient-derived organoids (PDO) recapture tumor heterogeneity with the possibility of performing drug screening. However, to best reproduce the patient's characteristics, it is necessary to develop a specific extracellular matrix (ECM) and introduce a tumor microenvironment (TME), which both represent an actual object of study to improve drug screening, particularly when used in targeted therapy and immunotherapy to guide therapeutic decisions. In this review, we summarize the current state of the art for the screening of PDOs, ECM, TME, and drugs in the setting of OC, as well as discussing the clinical implications and future perspectives for the research of OC organoids.
RESUMO
This practice guideline provides updated evidence for the gynecologist who performs endometrial biopsy (EB) in gynecologic clinical practice. An international committee of gynecology experts developed the recommendations according to AGREE Reporting Guideline. An adequate tissue sampling is mandatory when performing an EB. Blind methods should not be first choice in patients with suspected endometrial malignancy. Hysteroscopy is the targeted-biopsy method with highest diagnostic accuracy and cost-effectiveness. Blind suction techniques are not reliable for the diagnosis of endometrial polyps. In low resources settings, and in absence of the capacity to perform office hysteroscopy, blind techniques could be used for EB. Hysteroscopic punch biopsy allows to collect only limited amount of endometrial tissue. grasp biopsy technique should be considered first choice in reproductive aged women, bipolar electrode chip biopsy should be preferred with hypotrophic or atrophic endometrium. EB is required for the final diagnosis of chronic endometritis. There is no consensus regarding which endometrial thickness cut-off should be used for recommending EB in asymptomatic postmenopausal women. EB should be offered to young women with abnormal uterine bleeding and risk factors for endometrial carcinoma. Endometrial pathology should be excluded with EB in nonobese women with unopposed hyperestrogenism. Hysteroscopy with EB is useful in patients with abnormal bleeding even without sonographic evidence of pathology. EB has high sensitivity for detecting intrauterine pathologies. In postmenopausal women with uterine bleeding, EB is recommended. Women with sonographic endometrial thickness > 4 mm using tamoxifen should undergo hysteroscopic EB.

The main aim of our study was to describe the surgical technique and evaluate the feasibility, efficacy and safety of a vaginal-laparoscopic repair (VLR) of iatrogenic vesico-vaginal fistulae (VVF). Between April-2009 and November-2017, we retrospectively reviewed all clinical, radiological and surgical details of surgery for benign or malignant disease and ended up with VVF. All patients were diagnosed by CT urogram, cystogram and clinical test. The surgical technique was standardised and is described here. Eighteen patients developed VVF after hysterectomy, three after caesarean section and three after hysterectomy and pelvic lymphadenectomy. Twenty-two patients had an average 3 (range 1-5) attempts at fistula repair in other hospitals. In one patient, five attempts were made. The mean size of the fistula was 2.4 cm (range 0.7-3.1 cm). A median 8 weeks (6-16) conservative management with Foley catheter failed in all patients. No conversion to laparotomy and no complication occurred at VLR. Median hospitalisation was 1.4 days (range 1-3). The latter confirmed all patients were dry and tested negative at a repeated filling test. At 36 months follow-up, all patients remained dry. In conclusion, VLR successfully repaired VVF in all patients with primary and persistent VVF. The technique was safe and effective.

PURPOSE: To summarize available evidence comparing the transdermal and the oral administration routes of hormone replacement therapy (HRT) in postmenopausal women. METHODS: We performed a systematic review of the literature on multiple databases between January 1990 and December 2021. We included randomized controlled trials and observational studies comparing the transdermal and oral administration routes of estrogens for HRT in postmenopausal women regarding at least one of the outcomes of interest: cardiovascular risk, venous thromboembolism (VTE), lipid metabolism, carbohydrate metabolism, bone mineral density (BMD), and risk of pre-malignant and malignant endometrial lesions, or breast cancer. RESULTS: The systematic literature search identified a total of 1369 manuscripts, of which 51 were included. Most studies were observational and of good quality, whereas the majority of randomized controlled trials presented a high or medium risk of bias. Oral and transdermal administration routes are similar regarding BMD, glucose metabolism, and lipid profile improvements, as well as do not appear different regarding breast cancer, endometrial disease, and cardiovascular risk. Identified literature provides clear evidence only for the VTE risk, which is higher with the oral administration route. CONCLUSIONS: Available evidence comparing the transdermal and oral administration routes for HRT is limited and of low quality, recommending further investigations. VTE risk can be considered the clearest and strongest clinical difference between the two administration routes, supporting the transdermal HRT as safer than the oral administration route.

Luteinised unruptured follicle syndrome (LUFS) is a cause of infertility consisting in the unruptured of the dominant follicle after the LH-surge. In fact, during assisted reproductive treatments (ART) clomiphene citrate and letrozole are frequently administered in order to achieve ovulation. However, considering the pathophysiology of LUFS, new possible therapy can be proposed. On this scenario, we performed a review of the literature searching for LUFS recurrency and its impact in infertility and ART. An inflammation theory has been proposed that can be fuel for further therapeutic possibilities. In particular, considering the increase in granulocytes accumulation, the granulocyte colony-stimulating factor (G-CSF) administration has been proposed as target therapy in IUI cycles hampered by LUFS. Although data are encouraging, randomised controlled trials are needed in order to confirm the efficacy of G-CSF administration for LUFS patients.

This systematic review aims to evaluate the effectiveness of pharmacological and non-pharmacological strategies for pain relief in women during contrast-enhanced ultrasound for the assessment of tubal patency and uterine disease, compared with placebo or no intervention. In December 2021, we searched the electronic databases (Pubmed, Embase, Sciencedirect, the Cochrane library and Clinicaltrials.gov) without date restriction: We identified 10 randomized control trials (RCTs) (2098 women) eligible for this systematic review, after applying our inclusion and exclusion criteria. Among these, five studies compared the use of painkillers with the placebo, two studies compared different catheter positions in the cervix or in the uterine cavity, and two others considered different temperatures of the contrast medium, as a method to reduce pain. Topical lidocaine applied before the procedure may be associated with effective pain relief during hysterosonography, though the quality of this evidence is low. New echogenic contrast agents and their temperature at 37 °C ensure a less painful procedure. There is insufficient evidence to draw conclusions on the efficacy of other analgesics or strategies.
RESUMO
The main goal of our study was to evaluate the surgical technique, the feasibility and patient's satisfaction of multiple surgeries: Risk-reducing salpingo-oophorectomy (RRSO) combined with mastectomy in patients with BRCA 1-2 mutation carriers. We conducted a retrospective analysis of patients with BRCA 1-2 variants who underwent RRSO combined with risk-reducing bilateral mastectomy (RRBM) or surgeries for breast cancer from January-2015 to December-2021. We collected data about surgeries, complications, and patients' satisfaction using a questionnaire submitted 30 days after surgery. We included 54 patients. Forty-eight patients underwent RRSO, and six patients underwent RRSO + Total laparoscopic hysterectomy (LTH). The minor postoperative complications within 30 days were four: one breast seromas aspiration (1.9%), one infectious reconstructive complication treated with antibiotics therapy (1.9%), one Red-Breast-Syndrome (1.9%) and one trocar abdominal hematoma (1.9%) associated with RRSO. The major postoperative complications within 30 days were five: two evacuations of a breast hematoma (3.7%) and three infectious reconstructive complications treated with removal expander/implant (5.6%). No postoperative complications after 30 days were observed. According to the satisfaction questionnaire, more than 90% of patients were satisfied and would have combined surgery again. In conclusion, the multiple surgeries seem feasible and safety with a single anesthesia, a single surgical time, a single postoperative recovery, and a high patients' satisfactions without increasing morbidity.
RESUMO
Objective: we performed a systematic review/meta-analysis to evaluate the impact of septate uterus and hysteroscopic metroplasty on pregnancy rate-(PR), live birth rate-(LBR), spontaneous abortion-(SA) and preterm labor (PL) in infertile/recurrent miscarriage-(RM) patients. Data sources: a literature search of relevant papers was conducted using electronic bibliographic databases (Medline, Scopus, Embase, Science direct). Study eligibility criteria: we included in this meta-analysis all types of observational studies that evaluated the clinical impact of the uterine septum and its resection (hysteroscopic metroplasty) on reproductive and obstetrics outcomes. The population included were patients with a diagnosis of infertility or recurrent pregnancy loss. Study appraisal and synthesis methods: outcomes were evaluated according to three subgroups: (i) Women with untreated uterine septum versus women without septum (controls); (ii) Women with treated uterine septum versus women with untreated septum (controls); (iii) Women before and after septum removal. Odds ratios (OR) with 95% confidence intervals (CI) were calculated for the outcome measures. A p-value < 0.05 was considered statistically significant. Subgroup analysis was performed according to the depth of the septum. Sources of heterogeneity were explored by meta-regression analysis according to specific features: assisted reproductive technology/spontaneous conception, study design and quality of papers included Results: data from 38 studies were extracted. (i) septum versus no septum: a lower PR and LBR were associated with septate uterus vs. controls (OR 0.45, 95% CI 0.27−0.76; p < 0.0001; and OR 0.21, 95% CI 0.12−0.39; p < 0.0001); a higher proportion of SA and PL was associated with septate uterus vs. controls (OR 4.29, 95% CI 2.90−6.36; p < 0.0001; OR 2.56, 95% CI 1.52−4.31; p = 0.0004). (ii) treated versus untreated septum: PR and PL were not different in removed vs. unremoved septum(OR 1.10, 95% CI 0.49−2.49; p = 0.82 and OR 0.81, 95% CI 0.35−1.86; p = 0.62); a lower proportion of SA was associated with removed vs. unremoved septum (OR 0.47, 95% CI 0.21−1.04; p = 0.001); (iii) before-after septum removal: the proportion of LBR was higher after the removal of septum (OR 49.58, 95% CI 29.93−82.13; p < 0.0001) and the proportion of SA and PL was lower after the removal of the septum (OR 0.02, 95% CI 0.02−0.04; p < 0.000 and OR 0.05, 95% CI 0.03−0.08; p < 0.0001) Conclusions: the results show the detrimental effect of the uterine septum on PR, LBR, SA and PL. Its treatment reduces the rate of SA.
RESUMO
Transvaginal ultrasound (TVUS) represents an accurate and noninvasive technique to investigate endometrial thickness (ET) in the early diagnosis of endometrial cancer (EC). In the literature, for maximum ET there is no consensus on the cutoff value for normal ET in postmenopause for either symptomatic or asymptomatic women. Most patients with EC present with postmenopausal bleeding (PMB) and in these patients is necessary to perform TVUS to evaluate ET as an indicator for endometrial biopsy. On the contrary, if ET is incidentally detected in postmenopausal patients without bleeding, endometrial sampling for a postmenopausal woman without bleeding should not be routinely performed, although it is estimated that up to 15% of EC occurs in women without vaginal bleeding. The aim of our review was to give clinicians necessary and useful knowledge on the role of TVUS and ET for early detection of EC in their daily routine practice. Based on the most important studies in the literature, we summarized that in premenopausal woman with abnormal uterine bleeding, an optimal cutoff for ET has not yet been established. For postmenopausal women with PMB, at low risk, and ET <4 mm, a follow-up scan could be offered, and for women with ET ≥4 mm, office hysteroscopy-guided endometrial sampling is recommended independently of ET results. On the other hand, in postmenopausal women with PMB and at high risk of EC, office hysteroscopy-guided endometrial sampling is necessary. In postmenopausal women without PMB and ET ≥4 mm, arbitrary endometrial sampling is not recommended, but evaluated case by case based on risk factors. In conclusion, there is broad consensus on the importance of TVUS and the need for further investigation based on risk factors of EC.
