Role of sentinel lymph node biopsy with indocyanine green and site of injection in endometrial cancer.

PURPOSE OF REVIEW: The aim of the present narrative review is to summarize the state of art on sentinel lymph node biopsy (SLNB) in endometrial cancer, with a special focus on indocyanine green (ICG) as adopted tracer. RECENT FINDINGS: Over the years, the surgical nodal staging in patients with endometrial cancer has been intensively investigated. Traditionally, systematic pelvic and para-aortic lymphadenectomy represented the gold standard surgical treatment to assess nodal involvement of the tumor. Through the last two decades, SLNB has gradually replaced lymphadenectomy as a more targeted procedure. A great heterogeneity of tracers and injection techniques have been proposed to perform SLNB. However, no universally accepted recommendations are still available. SUMMARY: SLNB has nowadays almost replaced pelvic lymphadenectomy in low-risk endometrial cancers, offering a better safety profile while being related to a comparable nodal involvement sensitivity. Currently, ICG is considered to be the most used tracer among others. Different injection sites have been proposed, with different detection features. While ICG cervical injection is nowadays the suggested technique for SLNB, noncervical injection techniques, such as hysteroscopic and combined procedures, seem to have a better accuracy in para-aortic nodal assessment, which have a role in high-risk endometrial cancers.

Integrated histological parameters define prognostically relevant groups in atypical endometrial hyperplasia/endometrioid intraepithelial neoplasia.

OBJECTIVE: To assess the risk of endometrial carcinoma following a diagnosis of atypical hyperplasia/endometrioid intraepithelial neoplasia by endometrial biopsy, stratified based on integrated histological parameters. METHODS: All women with atypical hyperplasia/endometrioid intraepithelial neoplasia undergoing hysterectomy within 1 year of diagnosis without progestin treatment were included. Patients were subdivided into three study groups, based on two criteria: (a) grade of nuclear atypia and (b) foci (<2 mm) of confluent glands with no intervening stroma: low-grade, high-grade, and confluent glands. The rate of endometrial carcinoma on the subsequent hysterectomy was assessed in each study group, and differences between study groups were assessed using Fisher's exact test, with a significant p value <0.05. Reproducibility was assessed by using Cohen's κ. RESULTS: Ninety-six patients were included. Overall, 36 of 96 patients (37.5%) had endometrial carcinoma on the subsequent hysterectomy. The number of endometrial carcinomas was 4 of 42 (9.5%) in the low-grade group, 14 of 28 (50.0%) in the high-grade group, and 18 of 26 (69.2%) in the confluent glands group. The rate of endometrial carcinoma was significantly higher in the high-grade group than in the low-grade group (p<0.001), whereas it did not significantly differ between the high-grade group and the confluent glands group (p=0.176). The reproducibility among pathologists was moderate for low-grade versus high-grade (κ=0.58) and substantial for confluent glands versus low-grade (κ=0.63) and high-grade (κ=0.63). CONCLUSION: Atypical hyperplasia/endometrioid intraepithelial neoplasia can be stratified into prognostically relevant groups based on integrated histological parameters, with a possible major impact on patient management.

Assessment of sentinel Lymph node mapping with different volumes of Indocyanine green in early-stage ENdometrial cancer: the ALIEN study.

OBJECTIVE: To evaluate the impact of different volumes of indocyanine green (ICG) on the detection rate and bilateral mapping of sentinel lymph nodes in patients with apparent uterine-confined endometrial cancer. METHODS: All patients who underwent surgical staging with sentinel node mapping in six reference centers were included. Two different protocols of ICG intracervical injection were used: (1) 2 mL group: total volume of 2 mL injected superficially; (2) 4 mL group: total volume of 4 mL, 2 mL deeply and 2 mL superficially. Logistic regression was used to analyze factors that could influence dye migration and detection rates. A sensitivity analysis was carried out to determine how independent variables could affect the sentinel node detection rate. RESULTS: Of 442 eligible patients, 352 were analyzed (172 in the 2 mL group and 180 in the 4 mL group). The bilateral detection rates of the 2 mL and 4 mL groups were 84.9% and 86.1%, respectively (p=0.76). The overall detection rate was higher with a volume of 4 mL than with 2 mL (97.8% vs 92.4%, respectively; p=0.024). In the univariate analysis the rate of bilateral mapping fell from 87.5% to 73.5% when the International Federation of Gynecology and Obstetrics (FIGO) 2009 tumor stage was >IB (p=0.018). In the multivariate analysis, for both overall and bilateral detection rates a statistically significant difference emerged for the volume of ICG injected and FIGO 2009 stage >IB. Increasing body mass index was associated with worse overall detection rates on univariate analysis (p=0.0006), and significantly decreased from 97% to 91% when the body mass index exceeded 30 kg/m2 (p=0.05). CONCLUSIONS: In patients with early-stage endometrial cancer, a volume of 2 mL ICG does not seem to compromise the bilateral detection of sentinel lymph nodes. In women with obesity and FIGO 2009 stage >IB, a 4 mL injection should be preferred.

Robot-Assisted Partial Cystectomy for Deep Infiltrating Endometriosis of the Bladder With the Hugo RAS System.

OBJECTIVE: Involvement of the lower urinary tract is found in 0.2 to 2.5% of all deep infiltrating endometriosis (DIE) [1,2]. The bladder is the most affected organ with a prevalence of up to 80% of cases [3]. Patients with bladder endometriosis are often symptomatic (dysuria, hyperactive bladder, recurrent urinary tract infections, and hematuria). Surgery is the gold standard treatment for this condition when medical therapy fails [1,2]. Several studies have shown the feasibility, effectiveness, and safety of the laparoscopic approach [4] but data about robotic-assisted approach are missing in literature. Currently, novel platforms are entering the market and the Hugo™RAS (Medtronic, Minneapolis, USA) is a new system (HRS) consisting of an open console with 3D-HD screen and a multimodular bedside units. Even if some series are already available for radical cystectomies for oncologic purposes [5], a full description of DIE surgery performed with HRS is still lacking. Aim of this video-article is to show our technique and surgical setup to carry out a complex case of anterior compartment DIE. DESIGN: A step-by-step explanation of surgical technique with narrated video footage. SETTING: Tertiary Level Academic Hospital "IRCCS Azienda Ospedaliero-Universitaria di Bologna" Bologna, Italy. INTERVENTION: A 36-year-old nulliparous woman affected by DE was referred to our center due to severe dyspareunia, dysuria with hematuria and postvoiding pain not responsive to oral progestins. The preoperative work up consisted of a gynecological examination, pelvic ultrasound and MRI that showed the presence of an endometriotic nodule of the bladder base. All possible therapeutic strategies and related complications have been discussed with the patient before the signature of the informed consent. To carry out the procedure a "straight" port placement in a "compact" docking configuration [6] was installed. After developing the paravesical spaces bilaterally, the bladder nodule was approached in a latero-medial direction then a partial cystectomy with macroscopical free margins was performed. A double layer horizontal running suture with barbed thread was used to repair the bladder wall. CONCLUSION: To the best of our knowledge, this is the first case of bladder endometriotic nodule excision performed with HRS. We explained our technique and robotic set-up to successfully manage a compelx case of DIE of the bladder. VIDEO ABSTRACT.

Hysteroscopic Transillumination as a Guide for Laparoscopic Excision of Rudimentary Uterine Horn: A Winning Duo.

STUDY OBJECTIVE: Anatomic anomalies of the female reproductive genital tract affect approximately 5.5% of women [1]. The hemiuterus or class U4 by the European Society of Human Reproduction and Embryology / European Society for Gynaecological Endoscopy 2013 classification is a rare congenital malformation defined as a unilateral uterine development, with a contralateral part that could be either incompletely formed or absent. This class is divided into 2 subclasses depending on the presence or not of a functional rudimentary cavity (U4a/U4b) [2]. This work aimed to share our experience performing an hysteroscopic and laparoscopic combined technique to surgically manage this uterine malformation exploiting the hysteroscopic transillumination. DESIGN: A step-by-step explanation of surgical technique with narrated video footage. SETTING: Tertiary Level Academic Hospital "IRCCS Azienda Ospedaliero - Universitaria di Bologna" Bologna, Italy. INTERVENTIONS: A 32-year-old woman with a symptomatic (severe dysmenorrhea and chronic pelvic pain) suspected U4a uterine malformation diagnosed at our center was scheduled for laparoscopic removal of the right uterine horn and ipsilateral salpingectomy exploiting the contemporary hysteroscopic transillumination guidance. We selected this approach to avoid possible complications owing to the anatomic anomalies that are very common in these cases [3,4]. After coagulation and section of the right round ligament at the uterine angle and opening of the right broad ligament, access to the retroperitoneum was obtained to directly visualize the entire course of ureter and the uterine artery. The right uterine artery was coagulated and sectioned at the uterus. Then, the hysteroscope was introduced to the uterine fundus and the light source brightness was increased up to 100% to allow an adequate transmural visualization of the uterine defect from the laparoscope. Once the defect edge was well highlighted, the right uterine horn was isolated and removed using a monopolar hook, taking care to preserve an adequate amount of myometrium. A double layer running suture with barbed absorbable thread (V-Loc) for reconstructive purposes was performed. The specimen was retrieved inside an endobag to allow a safe extraction. Right salpingectomy was then performed. CONCLUSION: Considering the great anatomic variability of this condition, this type of surgery is not always simple. Indeed, the borders between the uterus and the rudimentary uterine horn are often not perfectly recognizable; this can lead to accidental removal of healthy myometrium and increase the risk of perioperative bleeding [5]. In our experience, the combined hysteroscopic and laparoscopic combined technique allows the surgeon to better delimit the borders of the hemiuterus, providing a more conservative and safer surgery. Hysteroscopic transillumination offers the possibility to modulate the radicality in the resection of the rudimentary horn and in the final treatment of dysmorphism.

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.

"RAIL BIOPSY" A Novel and Useful Technique for Hysteroscopic Endometrial Target Biopsy.

STUDY OBJECTIVE: Endometrial biopsy (EB) is one of the most common gynecologic procedures. Office-based EB has replaced procedures involving general/loco-regional anesthesia and cervical dilatation performed in the operating room [1-3]. The Grasp Biopsy seems to be the most appropriate EB technique for reproductive-aged women [1,2,4]. Recently, the Visual D&C performed with hysteroscopic tissue removal devices has shown to be a valid alternative [5]. However, it is often difficult to obtain an adequate specimens in peri/post-menopausal women with hypo/atrophic endometrium [2]. Our aim is to show a novel hysteroscopic EB technique called "Rail Biopsy" which requires widespread and cheap instruments. DESIGN: A step-by-step explanation of surgical techinque with narrated video footage. SETTING: Tertiary Level Academic Hospital "IRCCS Azienda Ospedaliero-Universitaria di Bologna" Bologna, Italy. INTERVENTIONS: We performed the "Rail Biopsy" technique with a 5.0 mm Continuous Flow Operative Hysteroscope with a 30° Lens and a 5Fr operative channel. We identify the endometrial target area (ETA), and we create a first track cutting through the endometrium in a caudo-cranial direction using cold scissors. We repeat the procedure, creating a second parallel track, thus completing our "rail" and isolating a wide ETA. Then, in the caudo-cranial direction, we cut through the stromal layer beneath the ETA. With a 5Fr cold grasping forceps, we clench the cranial edge of the ETA, and we remove it from the uterine cavity. A high-quality specimen, even in the case of hypo/atrophic endometrium or focal sessile lesions, can be obtained with this technique. The crucial aspect of the "Rail Biopsy" indeed is cutting through the stromal tissue while the endometrium is minimally touched, avoiding thermal damage deriving from electrosurgery. The instruments required are widespread and cheap. Moreover, this technique can be performed on any wall of the uterus, under vision, and, in the majority of patients, in an office-setting without cervical dilatation or general/loco-regional anesthesia, making it an attractive alternative to hysteroscopy performed in the operating room setting. Further studies comparing "Rail Biopsy" to other EB techniques are needed. CONCLUSION: We showed a novel approach for hysteroscopic EB that may be particularly useful in patients with hypo/atrophic endometrium, easy to learn and with low costs. VIDEO ABSTRACT.

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.

Feasibility of Intraoperative Proctosigmoidoscopy After Discoid Bowel Resection for Deep Infiltrating Endometriosis: A Pilot Multicenter Study.

STUDY OBJECTIVE: Although surgery is the gold standard treatment for pain refractory to medical management or partial occlusion owing to rectosigmoid endometriosis, surgical resection can be associated with major perioperative complications. From general surgery experience, intraoperative proctosigmoidoscopy has shown encouraging results as a feasible, safe, and effective technique in reducing the risk of complications related to intestinal anastomosis after segmental resection. Unfortunately, there are no studies evaluating its role after discoid resection for rectosigmoid endometriosis. DESIGN: A pilot, multicentric, observational, prospective, cohort study. SETTING: Two academic hospitals, from March 1 to December 31, 2022. PATIENTS: We enrolled all consecutive fertile-age patients affected by symptomatic endometriosis scheduled for laparoscopic discoid bowel resection. Inclusion criteria were (1) age between 18 and 50 years, (2) diagnosis of rectosigmoid endometriosis performed by transvaginal ultrasound and/or magnetic resonance imaging, and (3) women scheduled for laparoscopic discoid bowel resection of endometriosis at low risk of segmental resection. INTERVENTIONS: During data analysis, enrolled patients were divided into 2 study groups for comparisons based on whether or not the intraoperative proctosigmoidoscopy was performed upon surgeons' discretion after discoid resection for treating endometriosis, in addition to standard integrity tests. Primary outcome was the rate of intraoperative proctosigmoidoscopy success. Secondary study outcomes were the differences between the intraoperative proctosigmoidoscopy group and the nonintraoperative proctosigmoidoscopy group in (1) mean of total operative time and (2) rate of perioperative complications. MEASUREMENTS AND MAIN RESULTS: A total of 28 patients were enrolled and equally distributed in the 2 groups. The rate of intraoperative proctosigmoidoscopy success was 86%. No significant difference was reported between the 2 groups in terms of total operative time (p = .1) and intraoperative and postoperative complications (p = .5 and p = 1, respectively), with no surgical complication related to intraoperative proctosigmoidoscopy. CONCLUSION: Intraoperative proctosigmoidoscopy seems as a feasible and non-time-consuming intraoperative procedure in women undergone discoid resection for rectosigmoid endometriosis. Larger studies with longer follow-up period are necessary to confirm our findings and assess clinical benefits over standard procedure.

Safety and efficacy of non-ablative CO2 laser treatment of vulvo-vaginal atrophy in women with history of breast cancer.

PURPOSE: Breast cancer survivors (BCS) suffer severe vulvo-vaginal atrophy (VVA) and some of the most effective therapies are contraindicated. In literature we have no data about the non-ablative CO2 laser on these women. The aim of this study was to examine its efficacy, safety and acceptability in BCS. MATERIALS AND METHODS: The enrolled women underwent 3 sessions of laser therapy (t0, t1, t2) and a one-month follow up examination (t3). At each time point we measured objective signs of VVA via VHI (Vaginal Health Index) and VuHI (Vulvar Health Index) and subjective parameters (Dryness, Burning, Itching, Dysuria) via visual analog scales (VAS). In sexually active women we evaluated the sexual function with FSFI (Female Sexual Function Index), FSDS (Female Sexual Distress Score) scores and MENQOL (menopause quality of life questionnaire). RESULTS: We enrolled 26 BCS. The mean VHI, VuVHI, dryness and burning VAS scores improved significantly and this improvement was not influenced by the initial VVA grade. MENQOL sexual domain, Lubrication, Orgasm and Pain domains and FSFI total score improved significantly, while Desire, Arousal and Satisfaction domains of FSFI and FSDS did not. At t0 women using Aromatase Inhibitors suffered more severe vaginal dryness than women using Tamoxifen or no therapy, but the three subgroups improved without differences. No adverse event and minimum discomfort were reported. CONCLUSIONS: The non-ablative CO2 laser is a safe and effective treatment of VVA and has positive effects on sexual function in BCS regardless the use of adjuvant therapies and the initial grade of VVA.

Painful sexual intercourse, quality of life and sexual function in patients with endometriosis: not just deep dyspareunia.

PURPOSE: To evaluate the prevalence of deep and superficial dyspareunia in women with diagnosis of endometriosis. Secondly, to assess the temporal relation between deep and superficial dyspareunia in women reporting both symptoms (concomitant dyspareunia) and the impact on quality of life (QoL) and sexual function. METHODS: This is a cross-sectional cohort study that included fertile women with diagnosis of endometriosis. Enrolled subjects reported pain symptoms including dyspareunia and its temporal onset and completed two one-time validated questionnaires regarding sexual function (Female Sexual Function Index) and QoL (International QoL Assessment SF-36). RESULTS: Among the 334 enrolled patients, 75.7% (95%) reported dyspareunia. Women were divided into four groups according to the presence and type of dyspareunia: isolated superficial dyspareunia (6.3%), isolated deep dyspareunia (26.0%), concomitant dyspareunia (43.4%) and no dyspareunia (24.3%). Women with concomitant dyspareunia reported higher NRS scores than women with isolated dyspareunia or no dyspareunia (P ≤ 0.001). The majority of women with concomitant dyspareunia (56.6%) reported that deep dyspareunia developed before superficial dyspareunia. Women with concomitant dyspareunia reported worse QoL and worse sexual function than women with isolated dyspareunia or without dyspareunia (P ≤ 0.001). CONCLUSION: Dyspareunia is a common symptom in women with endometriosis, with many reporting concomitant deep and superficial dyspareunia. Concomitant dyspareunia can significantly impact sexual function and quality of life (QoL). Therefore, it is crucial to investigate dyspareunia thoroughly and differentiate between its types to tailor effective therapeutic strategies.

Conservative surgery versus colorectal resection for endometriosis with rectal involvement: a systematic review and meta-analysis of surgical and long-term outcomes.

PURPOSE: The optimal surgical approach for removal of colorectal endometrial deposits is unclear. Shaving and discoid excision of colorectal deposits allow organ preservation but risk recurrence with associated functional issues and re-operation. Formal resection risks potential higher complications but may be associated with lower recurrence rates. This meta-analysis compares peri-operative and long-term outcomes between conservative surgery (shaving and disc excision) versus formal colorectal resection. METHODS: The study was registered with PROSPERO. A systematic search was performed on PubMed and EMBASE databases. All comparative studies examining surgical outcomes in patients that underwent conservative surgery versus colorectal resection for rectal endometrial deposits were included. The two main groups (conservative versus resection) were compared in three main blocks of variables including group comparability, operative outcomes and long-term outcomes. RESULTS: Seventeen studies including 2861 patients were analysed with patients subdivided by procedure: colorectal resection (n = 1389), shaving (n = 703) and discoid excision (n = 742). When formal colorectal resection was compared to conservative surgery there was lower risk of recurrence (p = 0.002), comparable functional outcomes (minor LARS, p = 0.30, major LARS, p = 0.54), similar rates of postoperative leaks (p = 0.22), pelvic abscesses (p = 0.18) and rectovaginal fistula (p = 0.92). On subgroup analysis, shaving had the highest recurrence rate (p = 0.0007), however a lower rate of stoma formation (p < 0.00001) and rectal stenosis (p = 0.01). Discoid excision and formal resection were comparable. CONCLUSION: Colorectal resection has a significantly lower recurrence rate compared to shaving. There is no difference in complications or functional outcomes between discoid excision and formal resection and both have similar recurrence rates.

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.

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.

Prevalence and Risk Factors of Central Sensitization in Women with Endometriosis.

STUDY OBJECTIVE: To assess prevalence of central sensitization (CS) and its association with demographic and clinical factors in patients with endometriosis. DESIGN: Single-center, observational, cross-sectional study. SETTING: Tertiary center. PATIENTS: Consecutive patients with endometriosis referred to the center from January 15, 2022, to April 30, 2022. INTERVENTIONS: For each enrolled patient, demographic and clinical data were collected, and the presence of CS was measured using the CS Inventory questionnaire (score ≥40). MEASUREMENTS AND MAIN RESULTS: Primary study outcome was CS prevalence, and secondary study outcomes were the associations between demographic and clinical factors and CS. The 95% confidence intervals for CS prevalence were obtained with Bayesian-derived Jeffreys method, and the associations between CS and demographic and clinical factors were evaluated with the chi-square test and Fisher's exact test, where appropriate. The variables significantly associated with CS were then included in a multivariable logistic regression model. The significance level was set at .05 for all analyses. During the study period, 285 eligible women were enrolled. CS prevalence was 41.4% (95% confidence interval, 35.8-47.2). At univariable analysis, infertility, moderate to severe pain symptoms (except for dyschezia), altered bowel movements, posterolateral parametrium involvement, hormonal therapy failure (HTF), and most of central sensitivity syndromes were significantly associated with CS occurrence. Multivariable analysis only confirmed the significant association of CS with moderate to severe chronic pelvic pain, posterolateral parametrium involvement, HTF, migraine or tension-type headache, irritable bowel syndrome, and anxiety or panic attacks. CONCLUSION: CS has a high prevalence in patients with endometriosis, especially in those with moderate to severe chronic pelvic pain, posterolateral parametrium involvement, HTF, and 3 central sensitivity syndromes (i.e. migraine or tension-type headache, irritable bowel syndrome, anxiety or panic attacks). Given the association with HTF, identifying CS through CS Inventory might be useful to counsel the patient and to choose multimodal treatment.

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 LH. 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% confidence interval (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 Gonadotropin hormone-releasing hormone-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.

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.

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.

Diagnostic and prognostic value of Bcl-2 in uterine leiomyosarcoma.

BACKGROUND: Uterine leiomyosarcoma (uLMS) may show loss of expression of B-cell lymphoma-2 (Bcl-2) protein. It has been suggested that Bcl-2 loss may both be a diagnostic marker and an unfavorable prognostic marker in uLMS. OBJECTIVE: To define the diagnostic and prognostic value of Bcl-2 loss in uLMS through a systematic review and meta-analysis. METHODS: Electronic databases were searched from their inception to May 2020 for all studies assessing the diagnostic and prognostic value of Bcl-2 loss of immunohistochemical expression in uLMS. Data were extracted to calculate odds ratio (OR) for the association of Bcl-2 with uLMS vs leiomyoma variants and smooth-muscle tumors of uncertain malignant potential (STUMP), and hazard ratio (HR) for overall survival; a p value < 0.05 was considered significant. RESULTS: Eight studies with 388 patients were included. Loss of Bcl-2 expression in uLMS was not significantly associated with a diagnosis of uLMS vs leiomyoma variants and STUMP (OR = 2.981; p = 0.48). Bcl-2 loss was significantly associated with shorter overall survival in uLMS (HR = 3.722; p = 0.006). High statistical heterogeneity was observed in both analyses. CONCLUSION: Loss of Bcl-2 expression appears as a significant prognostic but not diagnostic marker in uLMS. The high heterogeneity observed highlights the need for further research and larger studies.

Prevalence of sonographic signs in women with uterine sarcoma: a systematic review and meta-analysis.

OBJECTIVE: To assess the prevalence of sonographic signs in women with uterine sarcoma. MATERIALS AND METHODS: A systematic review and meta-analysis were performed. Five electronic databases were searched from inception to June 2022 for all studies allowing calculation of the prevalence of sonographic signs in women with uterine sarcoma. Pooled prevalence with 95% confidence intervals was calculated for each sonographic sign and was a priori defined as "very high" when it was ≥ 80%, "high" when it ranged from 80% to 70%, and less relevant when it was ≤ 70%. RESULTS: 6 studies with 317 sarcoma patients were included. The pooled prevalence was: · 25.0% (95%CI:15.4-37.9%) for absence of visibility of the myometrium. · 80.5% (95%CI:74.8-85.2%) for solid component. · 78.3% (95%CI:59.3-89.9%) for inhomogeneous echogenicity of solid component. · 47.9% (95%CI:41.1-54.8%) for cystic areas. · 80.7% (95%CI:68.3-89.0%) for irregular walls of cystic areas. · 72.3% (95%CI:16.7-97.2%) for anechoic cystic areas. · 54.8% (95%CI:34.0-74.1%) for absence of shadowing. · 73.5% (95%CI:43.3-90.9%) for absence of calcifications. · 48.7% (95%CI:18.6-79.8%) for color score 3 or 4. · 47.3% (95%CI:37.0-57.8%) for irregular tumor borders. · 45.4% (95%CI:27.6-64.3%) for endometrial cavity not visualizable. · 10.9% (95%CI:3.5-29.1%) for free pelvic fluid. · 6.4% (95%CI:1.1-30.2%) for ascites. · 21.2% (95%CI:2.1-76.8%) for intracavitary process. · 81.5% (95%CI:56.1-93.8%) for singular lesion.. CONCLUSION: Solid component, irregular walls of cystic areas, and singular lesions are signs with very high prevalence, while inhomogeneous echogenicity of solid component, anechoic cystic areas, and absence of calcifications are signs with high prevalence. The remaining signs were less relevant.
