RESUMO
OBJECTIVE: Determine the cost-effectiveness for hysterectomy versus standard of care single agent chemotherapy for low-risk gestational trophoblastic neoplasia (GTN). METHODS: A cost-effectiveness analysis was conducted comparing single agent chemotherapy with hysterectomy using decision analysis and Markov modeling from a healthcare payer perspective in Canada. The base case was a 40-year-old patient with low-risk non-metastatic GTN that completed childbearing. Outcomes were life years (LYs), quality-adjusted life years (QALYs), incremental cost-effectiveness ratio (ICER), and adjusted 2022 costs (CAD). Discounting was 1.5% annually and the time horizon was the patient's lifetime. Model validation included face validity, deterministic sensitivity analyses, and scenario analysis. RESULTS: Mean costs for chemotherapy and hysterectomy arms were $34,507 and $17,363, respectively, while effectiveness measure were 30.37 QALYs and 31.04 LYs versus 30.14 QALYs and 30.82 Lys, respectively. The ICER was $74,526 (USD $54,516) per QALY. Thresholds favoring hysterectomy effectiveness were 30-day hysterectomy mortality below 0.2% and recurrence risk during surveillance above 9.2% (low-risk) and 33.4% (high-risk). Scenario analyses for Dactinomycin and Methotrexate led to similar results. Sensitivity analysis using tornado analysis found the cost to be most influenced by single agent chemotherapy cost and risk of resistance, number of weeks of chemotherapy, and probability of postoperative mortality. CONCLUSION: Compared to hysterectomy, single agent chemotherapy as a first-line treatment costs $74,526 for each additional QALY gained. Given that this cost falls below the accepted $100,000 willingness-to-pay threshold and waitlist limitations within public healthcare systems, these results support the continued use of chemotherapy as standard of care approach for low-risk GTN.

OBJECTIVE: Investigating for mismatch repair protein deficiency (MMRd), microsatellite instability (MSI), and Lynch syndrome (LS) is widely accepted in endometrial cancer, but knowledge is limited on its value in epithelial ovarian cancer (EOC). The primary objective was to evaluate the prevalence of mismatch repair protein deficiency (MMRd), microsatellite instability (MSI)-high, and Lynch syndrome (LS) in epithelial ovarian cancer (EOC), as well as the diagnostic accuracy of LS screening tests. The secondary objective was to determine the prevalence of MMRd, MSI-high, and LS in synchronous ovarian endometrial cancer and in histological subtypes. METHODS: We systematically searched the MEDLINE, Epub Ahead of Print, MEDLINE In-Process and Other Non-Indexed Citations, Cochrane Central Register of Controlled Trials, and Embase databases. We included studies analysing MMR, MSI, and/or LS by sequencing. RESULTS: A total of 55 studies were included. The prevalence of MMRd, MSI-high, and LS in EOC was 6% (95% confidence interval (CI) 5-8%), 13% (95% CI 12-15%), and 2% (95% CI 1-3%) respectively. Hypermethylation was present in 76% of patients with MLH1 deficiency (95% CI 64-84%). The MMRd prevalence was highest in endometrioid (12%) followed by non-serous non-mucinous (9%) and lowest in serous (1%) histological subtypes. MSI-high prevalence was highest in endometrioid (12%) and non-serous non-mucinous (12%) and lowest in serous (9%) histological subtypes. Synchronous and endometrioid EOC had the highest prevalence of LS pathogenic variants at 7% and 3% respectively, with serous having lowest prevalence (1%). Synchronous ovarian and endometrial cancers had highest rates of MMRd (28%) and MSI-high (28%). Sensitivity was highest for IHC (91.1%) and IHC with MSI (92.8%), while specificity was highest for IHC with methylation (92.3%). CONCLUSION: MMRd and germline LS testing should be considered for non-serous non-mucinous EOC, particularly for endometrioid. PRECIS: The rates of mismatch repair deficiency, microsatellite instability high, and mismatch repair germline mutations are highest in endometrioid subtype and non-serous non-mucinous ovarian cancer. The rates are lowest in serous histologic subtype.

OBJECTIVE: To determine the prevalence of underlying high-intermediate (high-IM) and high-risk endometrial cancer (EC) in patients with preoperative diagnosis of Endometrial intraepithelial neoplasia (EIN) and to assess the impact of the information retrieved from the sentinel lymph node (SLN) on adjuvant therapy. METHODS: Retrospective cohort study of women undergoing hysterectomy, optional bilateral salpingo-oophorectomy (BSO) and lymph nodes assessment for EIN between December 2007 and August 2021. RESULTS: One hundred and sixty two (162) eligible patients were included, of whom 101 (62.3%) had a final diagnosis of EIN, while 61 (37.7%) were ultimately diagnosed with carcinoma. Out of 15 patients with high-IM to high-risk disease (9.25% of all EIN), 12 had grade 2-3 EC including 8 with >50% myometrial invasion, 2 with serous subtype, 1 with cervical invasion and 2 with pelvic lymph nodes involvement. Of the 3 patients with grade 1 EC, one patient had disease involving the adnexa and 2 patients had tumor invading >50% of the myometrium and with lymphovascular space invasion (LVSI). Ten patients received vaginal brachytherapy after surgery, 3 patients with extrauterine spread were treated with systemic chemotherapy followed by vaginal brachytherapy and pelvic external-beam radiotherapy and 2 patients with early-stage serous carcinoma received chemotherapy followed by vaginal brachytherapy. CONCLUSIONS: Information from SLN, even when negative, can be helpful in the management of patients with EC after preoperative EIN, as some patients are found to have high-IM to high-risk disease on final pathology. These patients would require either re-staging surgery or adjuvant external beam radiotherapy, both could be avoided by proper staging.

OBJECTIVE: International societies advocate for gestational trophoblastic neoplasia referral to designated expert centers. This study assessed the impact of centralization of trophoblastic care on clinical outcomes. METHODS: A centralized program was implemented in 2018 at two affiliated academic hospitals, Princess Margaret Cancer Center and Mount Sinai Hospital. A retrospective analysis of patients treated between 2000 and 2022 was performed and the clinical outcomes were compared before (2000-2017) and after (2018-2022) centralization. Statistical analyses were performed with significance set as p<0.05. RESULTS: A total of 94 patients with trophoblastic neoplasia were included: 60 pre-centralization and 34 post-centralization, 79.8% low-risk and 18.1% high-risk. Centralization led to significant improvement for: (1) accurate score documentation (from 37.9% to 89.3%,); (2) contraception counseling (from 67.2% to 96.7%); (3) median time from diagnosis to chemotherapy (from 9 days to 1 day); and (4) incomplete follow-up (from 20.7% to 3.3%) (all p<0.05). First-line chemotherapy for low-risk neoplasia was dactinomycin in 47.9% and 87.0% pre- and post-centralization, respectively (p=0.005). The median number of chemotherapy cycles decreased from seven to four (p=0.01), and the median number of consolidation cycles increased from two to three (p<0.001). Serum human chorionic gonadotropin (hCG) levels of 10 000-100 000 IU/L were significantly associated with longer time to hCG normalization and higher risk of resistance to first-line chemotherapy compared with hCG levels <1000 IU/L. CONCLUSION: Centralization of trophoblastic neoplasia care leads to greater guideline compliance, faster chemotherapy initiation, fewer chemotherapy cycles with optimized consolidation, and enhanced surveillance completion. This supports the establishment of trophoblastic neoplasia expert centers.

OBJECTIVE: The implementation of a peri-operative care program based on enhanced recovery after surgery principles for minimally invasive gynecologic oncology surgery led to an improvement in same day discharge from 29% to 75% at our center. This study aimed to determine the program's economic impact. METHODS: Our initial enhanced recovery quality improvement program enrolled consecutive patients undergoing minimally invasive hysterectomy at a single center during a 12-month period and compared them to a pre-intervention cohort. The primary outcome was overall costs. The secondary outcomes were surgical and post-operative visit costs. The surgical visit costs included pre-operative and operating room, post-operative stay, pharmacy, and interventions costs. The 30-day post-operative visit costs included clinic and emergency room, and readmission costs. The costs for every visit were collected from the case-cost department and expressed in 2020 Canadian dollars (CAD). RESULTS: A total of 96 and 101 patients were included in the pre- and post-intervention groups, respectively. The median total cost per patient for post-intervention was $7252 compared with $8381 pre-intervention (p=0.02), resulting in a $1129 cost reduction per patient. The total cost for the program implementation was $134 per patient for a total cost of $13 106. The median post-operative stay cost was $816 post-intervention compared with $1278 pre-intervention (p<0.05). Statistically significant savings for the post-intervention group were also found for operative visit, operating room costs, and pharmacy (p<0.05). On multivariate analysis, surgical approach was the only factor associated with operating room costs, whereas both surgical approach and group (pre- vs post-intervention) impacted the total and post-operative stay costs (p<0.05). CONCLUSION: In addition to increasing the same day discharge rate after minimally invasive gynecologic oncology surgery, an enhanced recovery-based peri-operative care program led to significant reductions in cost.

Endocervical sampling is performed traditionally with an endocervical curette (ECC). The current study objective is to compare the histopathological performance of endocervical brush (ECB) and endocervical curette (ECC). A retrospective review was performed including patients included that underwent colposcopy with endocervical sampling using either method. A total of 127 samples were obtained with ECC and 98 with ECB. Histopathological diagnosis was obtained in 124 (97.6%) ECC samples and in 94 (95.9%) ECB samples (p = 0.46). The incidence of benign results was similar between ECC and ECB (117 (92.1%) versus 88 (89.8%) respectively (p = 0.28)). When combining information from endocervical sampling with cervical biopsies, the detection rate of high-grade pathologies was similar between the groups with 14 cases (17.7%) for ECC and 8 cases (17.0%) for ECB (p = 0.43). A scope review of the topic was performed, illustrating that studies favour either method. In conclusion, ECB and ECC perform similarly for providing a histopathological diagnosis on endocervical samples.IMPACT STATEMENTWhat is already known on this subject? Endocervical samples in colposcopy were traditionally obtained using an endocervical curette. Similarly, a brush can be used for histological sampling of the endocervical canal. However, it is unclear how the ability to obtain a histopathological diagnosis compares between the two techniques.What do the results of this study add? This single-institution experience with using endocervical brush and curette for endocervical sampling finds that both methods are acceptable and have a high ability to provide a histopathological diagnosis. Precisely, 4.1% of brush and 2.4% of curette samples had insufficient tissue.What are the implications of these findings for clinical practice and further research? The endocervical brush is an adequate sampling method for colposcopy, and can be safely used instead of the curette, based on clinician preference. Further studies could investigate how these methods compare from a patient perspective.

OBJECTIVE: We aimed to evaluate the surgical and oncological outcomes of elderly patients with intermediate to high-risk endometrial cancer undergoing staging with sentinel lymph node (SLN) sampling and pelvic lymphadenectomy. METHODS: We conducted a retrospective study of elderly (>65-year-old) patients diagnosed with endometrial cancer between December 2007 and August 2017. These patients had been treated at a single center in Montreal, Canada. We compared the surgical and oncological outcomes of three cohorts undergoing surgical staging in non-overlapping eras: 1) lymphadenectomy, 2) lymphadenectomy and SLN sampling, 3) SLN sampling alone. Using life tables, Kaplan-Meier survival curves and log-rank tests, we analyzed 2-year progression-free survival, overall survival, and disease-specific survival. RESULTS: Our study included 278 patients with a median age of 73 years (range; 65-91): 84 (30.2%) underwent lymphadenectomy, 120 (43.2%) underwent SLN sampling with lymphadenectomy, and 74 (26.6%) had SLN sampling alone. The SLN sampling alone group had shorter operative times with a median duration of 199 minutes (range, 75-393) compared with 231 (range, 125-403) and 229 (range, 151-440) minutes in the SLN sampling with lymphadenectomy and lymphadenectomy cohorts; respectively (p<0.001). The SLN sampling alone group also had lower estimated blood loss with a median loss of 20 mL (range, 5-150) vs 25 mL (range, 5-800) and 40 mL (range, 5-400) in the SLN sampling with lymphadenectomy and lymphadenectomy cohorts, respectively (p=0.002). The 2 year overall survival and progression-free survival were not significantly different between the three groups (p=0.45, p=0.51, respectively). On multivariable analysis after adjusting for age, American Society of Anesthesiologists (ASA) score, stage, grade, and lymphovascular space invasion, adding SLN sampling was associated with better overall survival, (HR 0.2, CI [0.1 to 0.6], p=0.006) and progression-free survival (HR 0.5, CI [0.1 to 1.0], p=0.05). CONCLUSION: Sentinel lymph node-based surgical staging is feasible and associated with better surgical outcomes and comparable oncological outcomes in elderly patients with intermediate and high-risk endometrial cancer.

OBJECTIVE: Risk-reducing salpingo-oophorectomy (RRSO) is standard treatment among women with BRCA mutations. The aim of this meta-analysis is to evaluate the risk of endometrial cancer (EC) in BRCA1 or BRCA2 germline mutation carriers and to examine the justifiability of prophylactic hysterectomy at the time of RRSO. DATA SOURCES: PubMed, Cochrane Central Register of Controlled Trials, BIOSIS, Medline (Ovid), Web of Science, ClinicalTrials.gov, and Google Scholar were searched. Eleven articles were selected and analyzed using the OpenMetaAnalyst 2012 software. METHODS OF STUDY SELECTION: Randomized controlled studies, cohort studies, and case-control studies evaluating the risk of EC and specifically uterine papillary serous carcinoma (UPSC) in germline BRCA1/2 mutation carriers were included. Articles were excluded if they did not meet the inclusion criteria, or if data were not reported and the authors did not respond to inquiries. We assessed the methodological quality of the included studies on the basis of the Newcastle-Ottawa scale. Dichotomous results from each of the studies eligible for the meta-analysis were expressed as the proportion of patients with EC or UPSC per total number of BRCA mutation carriers, with 95% confidence interval (CI). The Mantel-Haenszel statistical method was used. TABULATION, INTEGRATION, AND RESULTS: Eleven studies reported the outcome of interest and were included in the final meta-analysis. In total, 13 871 carriers of BRCA1 and BRCA2 mutations were identified. The pooled prevalence rates of EC and UPSC in BRCA1/2 mutation carriers were 82/13 827 (0.59%) and 19/11 582 (0.16%), respectively. The EC prevalence was 46/7429 (0.62%) in BRCA1 mutation carriers and 17/3546 (0.47%) in BRCA2 mutation carriers, with relative risk of 1.18 (95% CI, 0.7-2.0). For UPSC, the prevalence was 15/7429 (0.2%) and 3/3546 (0.08%) among BRCA1 and BRCA2 mutation carriers, respectively, (relative risk 1.39; 95% CI, 0.5-3.7). CONCLUSION: Most studies in this meta-analysis suggest a slightly increased risk of EC in BRCA mutation carriers, mainly for BRCA1. The decision regarding concurrent hysterectomy should be tailored individually to each patient on the basis of the patient's age, type of mutation, future need for hormone replacement treatment, history of breast cancer, tamoxifen use, and personal operative risks.

OBJECTIVE: Coronavirus disease 2019 (COVID-19) may present asymptomatically in a large proportion of cases in endemic areas. Accordingly, universal testing has been suggested as a potential strategy for reducing transmission in the obstetrical setting. We describe the clinical characteristics of patients who tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) during pregnancy at a designated COVID-19 hospitalization centre in Montréal, Québec. METHODS: A single-centre retrospective cohort was constructed to include all pregnant patients who tested positive for SARS-CoV-2 between March 22 and July 31, 2020, and received care at the Jewish General Hospital. Initially, testing was restricted to at-risk patients, identified through the use of a screening questionnaire. Beginning on May 15, 2020, universal testing was implemented, and all pregnant patients admitted to the hospital were tested. Data were collected through chart review. RESULTS: Of 803 patients tested for SARS-CoV-2 during the study period, 41 (5%) tested positive. Among those patients who were symptomatic, the most commonly reported symptoms were cough (53%), fever (37%), dyspnea (30%), and anosmia and/or ageusia (20%). Before the implementation of universal testing, 13% (3 of 24) of patients with SARS-CoV-2 were asymptomatic. After implementation of universal testing, 80% (8 of 10) of patients with SARS-CoV-2 were asymptomatic. CONCLUSION: Our findings suggest that most pregnant patients with SARS-CoV-2 are asymptomatic or have mild symptoms of COVID-19. Particularly in endemic areas, universal testing of pregnant patients presenting to the hospital should be strongly considered as an important measure to prevent in-hospital and community transmission of COVID-19.

We report on the perinatal outcomes of pregnant patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) from 2 hospitals in Montréal, Québec. Outcomes of 45 patients with SARS-CoV-2 during pregnancy were compared with those of 225 patients without infection. Sixteen percent of patients with SARS-CoV-2 delivered preterm, compared with 9% of patients without (Pâ¯=â¯0.28). Median gestational age at delivery (39.3 (interquartile range [IQR] 37.7-40.4) wk vs. 39.1 [IQR 38.3-40.1] wk) and median birth weight (3250 [IQR 2780-3530] g vs. 3340 [IQR 3025-3665] g) were similar between groups. The rate of cesarean delivery was 29% for patients with SARS-CoV-2. Therefore, we did not find important differences in outcomes associated with SARS-CoV-2. Our findings may be limited to women with mild COVID-19 diagnosed in the third trimester.

The association between the use of the intra-uterine device (IUD) and the risk of ovarian cancer is not well known. In this study, we sought to determine whether the use of an IUD is associated with a reduction in the risk of ovarian cancer. We searched Medline, EMBASE, Google Scholar, Scopus, ISI Web of Science and Cochrane database search, as well as PubMed (www.pubmed.gov) and RCT registry (www.clinicaltrials.gov) until the end of June 2019 to conduct a systematic review and meta-analysis comparing ever-use vs. never-use of an IUD and the risk of subsequent ovarian cancer. We obtained 431 records, of which 9 met inclusion criteria. A total of five case-control studies and four cohort studies were retrieved to establish the risk of ovarian cancer amongst ever-users of an IUD. Relative to the never-use of the IUD, ever-use conferred a lower risk of ovarian cancer with an estimated OR of 0.67 95% CI [0.60 - 0.74], p < .0001, I2 = 71%. This relationship remained significant when results were restricted to studies evaluating the levonorgestrel intrauterine system (LNG-IUD) alone, with an estimated OR of 0.58 95% CI [0.47 - 0.71], p < .0001, I2 = 0%, as well as when the analysis was stratified by study design, with an OR of 0.64 95% CI [0.56 - 0.74] for case-control studies, and OR of 0.71 95% CI [0.60 - 0.84] for cohort studies (p < .0001). Ever-use of an intrauterine contraceptive device reduces the risk of ovarian cancer by an average of 30%. Whether differences exist for duration of use, use of type-specific device, and specific tumour type needs to be addressed in future studies.Impact statementWhat is already known on this subject? The use of IUDs is very common practice in today's society. Its benefits regarding contraception, the treatment of abnormal uterine bleeding and even the reduction of the rates of endometrial cancer are well established. However, whether IUD's are associated with a reduction in the risk of ovarian cancer is unknown.What do the results of this study add? In this study, we show that the ever-use of the IUD reduces the risk of ovarian cancer by an average of 30%. We provide insight regarding the potential theories that may underlie these findings.What are the implications of these findings for clinical practice and/or further research? future studies will need to determine whether the beneficial effects found are a function of duration of use, of type-specific device, or specific tumour types. In the meantime, these findings may serve clinicians to reassure and counsel patients about the added benefits of intra-uterine devices.

OBJECTIVE: To evaluate long-term oncological outcomes and the added value of sentinel lymph node sampling (SLN) compared to pelvic lymph node dissection (LND) in patients with endometrial cancer (EC). METHODS: During the evaluation phase of SLN for EC, we performed LND and SLN and retrospectively compared the oncologic outcome with the immediate non-overlapping historical era during which patients underwent LND. RESULTS: From 2007 to 2010, 193 patients underwent LND and from December 2010 to 2014, 250 patients had SLN mapping with completion LND. Both groups had similar clinical characteristics. During a median follow-up period of 6.9 years, addition of SLN was associated with more favorable oncological outcomes compared to LND with 6-year overall survival (OS) of 90% compared to 81% (p = 0.009), and progression free survival (PFS) of 85% compared to 75% (p = 0.01) respectively. SLN was associated with improved OS (HR 0.5, 95% CI 0.3-0.8, p = 0.004), and PFS (HR 0.6, 95% CI 0.4-0.9, p = 0.03) in a multivariable analysis, adjusted for age, ASA score, stage, grade, non-endometrioid histology, and LVSI. Patients who were staged with SLN were less likely to have a recurrence in the pelvis or lymph node basins compared to patients who underwent LND only (6-year recurrence-free survival 95% vs 90%, p = 0.04). CONCLUSION: Addition of SLN to LND was ultimately associated with improved clinical outcomes compared to LND alone in patients with endometrial cancer undergoing surgical staging, suggesting that the data provided by the analysis of the SLN added relevant clinical information, and improved the decision on adjuvant therapy.

OBJECTIVE: To evaluate the impact of surgical wait times on outcome of patients with grade 3 endometrial cancer. METHODS: All consecutive patients surgically treated for grade 3 endometrial cancer between 2007 and 2015 were included. Patients were divided into two groups based on the time interval between endometrial biopsy and surgery: wait time from biopsy to surgery ≤12 weeks (84 days) vs more than 12 weeks. Survival analyses were conducted using log-rank tests and Cox proportional hazards models. RESULTS: A total of 136 patients with grade 3 endometrial cancer were followed for a median of 5.6 years. Fifty-one women (37.5%) waited more than 12 weeks for surgery. Prolonged surgical wait times were not associated with advanced stage at surgery, positive lymph nodes, increased lymphovascular space invasion, and tumor size (P = .8, P = 1.0, P = .2, P = .9, respectively). In multivariable analysis adjusted for clinical and pathological factors, wait times did not significantly affect disease-specific survival (adjusted hazard ratio [HR]: 1.2, 95% confidence interval [CI], 0.6-2.5, P = .6), overall survival (HR: 1.1, 95% CI, 0.6-2.1, P = .7), or progression-free survival (HR: 0.9, 95% CI, 0.5-1.7, P = .8). CONCLUSION: Prolonged surgical wait time for poorly differentiated endometrial cancer seemed to have a limited impact on clinical outcomes compared to biological factors.

CONTEXTE: L'hématome du grand droit (HGD) est une cause rare mais importante de douleur abdominale pendant la grossesse. CAS: Une femme de 32 ans a consulté à 316 semaines de grossesse en raison de douleurs abdominales du côté droit. L'échographie a révélé une structure hétérogène compatible avec un HGD. Une prise en charge s'est composée d'un traitement symptomatique au moyen d'analgésiques et d'un suivi obstétrical et échographique. L'échographie a révélé la résorption de l'HGD après 6 semaines. À 38 semaines de grossesse, la patiente a subi un déclenchement artificiel du travail pour cause de pré-éclampsie et a donné naissance à une fille en bonne santé. CONCLUSION: Notre étude de cas présente un HGD spontané survenu à 32 semaines de grossesse, lequel a été pris en charge par traitement symptomatique. La grossesse s'est soldée par un accouchement à terme.

OBJECTIVE: To assess risk factors for lymph node involvement in patients with endometrial cancer and a body-mass index (BMI) ≥30â¯kg/m2. MATERIALS AND METHODS: A retrospective analysis was performed of obese patients diagnosed with endometrial carcinoma between 2007 and 2015, treated in a single center in Montreal. Preoperative variables evaluated were age, BMI, parity, and preoperative ASA score, grade, CA-125 and histology. Odds ratios (OR) and hazard ratios (HR) and their respective 95% confidence intervals (95%CI) were calculated using multivariable logistic regression and Cox proportional hazard models. RESULTS: The study included 230 women with BMI ≥30, 223 (97.0%) had complete staging. Pelvic lymph node involvement was detected in 26 patients (11.3%). Sentinel node detection and pelvic lymph node dissection decreased with increasing BMI (adjusted OR 0.86, 95%CI 0.76-0.97 and 0.76, 95%CI 0.59-0.96, respectively, per 1â¯kg/m2 increment). Pelvic lymph node involvement was inversely correlated with BMI (adjusted OR 0.88, 95%CI 0.79-0.99) and present in 16/85 (18.8%), 6/56 (10.7%), and 4/82 (4.9%) of patients with a BMI of 30.0-34.9, 35.0-39.9, and ≥40.0â¯kg/m2, respectively. Preoperative CA-125 was associated with lymph node involvement (adjusted OR 2.77, 95%CI 1.62-4.73, per quartile increment). CONCLUSION: Pelvic lymph node dissection might be omitted in selected cases of morbidly obese patients with failed sentinel nodes mapping and a low CA-125.

OBJECTIVE: The incidence of placenta accreta spectrum (PAS) has risen over the past decades, primarily in response to increasing Caesarean section rates. The surgical management of PAS is associated with significant morbidity, including hemorrhage and intensive care unit (ICU) admission. This study sought to evaluate the surgical outcomes of a PAS operative approach. METHODS: A single-centre retrospective chart review of all Caesarean hysterectomies for PAS by an assigned surgeon over a 16-year period was performed. Surgical outcomes were described (Canadian Task Force Classification II-2). RESULTS: The described surgical approach involves a midline skin incision, high midline hysterotomy, a rapid single-layer uterine closure with no placental removal attempt, constant cephalad uterine traction, and liberal choice of subtotal hysterectomy. A total of 47 patients were included: 19 (40.4%) with placenta accreta, 14 (29.8%) with placenta increta, and 14 (29.8%) with placenta percreta. Mean estimated blood loss was 1416 ± 699 mL, and mean operative time was 112 ± 49 minutes. Overall, 16 patients (34.0%) required blood transfusion, and 4 patients (8.5%) required ICU admission. The average hospitalization was 5.2 days, with no re-admission within 30 days. The use of internal iliac balloons did not result in a difference in blood loss or operative time (P > 0.05). Patients with placenta percreta had significantly more blood loss (Pâ¯=â¯0.02) and longer operative time (Pâ¯=â¯0.007) compared with those with placenta accreta and increta. CONCLUSION: The current surgical model for planned Caesarean hysterectomy for PAS exhibits a low complication rate. Further research is needed for developing a standardized approach to the management of PAS.

BACKGROUND: In twin pregnancies, elective cerclage placement based on obstetrical history or ultrasound findings has been shown to be ineffective and even harmful. There are currently no guidelines for the use of rescue cervical cerclage in twin pregnancies. CASE: The current report presents the case of a 33-year-old patient with monochorionic diamniotic twins (MCDA) found to have dilated cervix at 3.5cm with exposed membranes upon physical examination at 19 weeks and 3 days. An emergency McDonald cerclage was placed at 20 weeks and the patient carried the current pregnancy until 35weeks 6 days. CONCLUSION: Rescue cerclage represents an important option to consider in order to preserve twin pregnancies regardless of chorionicity.

OBJECTIVE: This study sought to assess the impact of an obstetrics and gynaecology (OBGYN) multidimensional technical skills training session on medical student self-perceived confidence, objective performance, clinical exposure, and interest in OBGYN. METHODS: OBGYN clerkship students were divided into control (i.e., traditional curriculum) and intervention (i.e., additional pre-rotation simulation training in vaginal delivery, suturing and knot tying, speculum and bimanual examinations, and intrapartum cervical examination) groups. Both groups underwent an objective structured clinical examination (OSCE) after the rotation and completed pre- and post-rotation questionnaires to assess confidence, clinical exposure, and interest in OBGYN. The primary outcomes were self-reported confidence and OSCE scores, and the secondary outcomes were clinical exposure and interest in OBGYN. RESULTS: A total of 148 students participated. Both groups reported least confidence with vaginal delivery and cervical examinations before the rotation. There was improved self-confidence across all skills after the rotation, with the intervention group demonstrating greater improvement for vaginal delivery (3.36 vs. 3.10; P < 0.05) and cervical examination (3.14 vs. 2.86; P < 0.05). The intervention group also demonstrated a trend towards higher OSCE scores for all skills, but only speculum and bimanual examinations reached statistical significance. The intervention increased exposure from "0 to 5" to "6 to 10" for vaginal delivery and suturing. There was no difference in interest in OBGYN between the two groups. CONCLUSION: A technical skills training session before OBGYN clerkship is feasible and has the potential to increase students' confidence, OSCE performance, and hands-on procedural exposure. The optimal combination of skills to be included still needs to be defined.

Endometrial carcinoma (EC) is traditionally treated with surgery and adjuvant treatment depending on clinicopathological risk factors. The genomic analysis of EC in 2013 and subsequent studies using immunohistochemistry have led to the current EC molecular classification into: polymerase epsilon mutated (POLEmut), p53 abnormal (p53abn), mismatch repair deficient (MMRd), and no specific molecular profile (NSMP). The four groups have prognostic value and represent a promising tool for clinical decision-making regarding adjuvant treatment. Molecular classification was integrated into the recent European Society of Gynecologic Oncology (ESGO) management guidelines. POLEmut EC has favorable outcomes and retrospective studies found that omitting adjuvant treatment is safe in this group; two prospective clinical trials, PORTEC-4 and TAPER, are ongoing to assess this. p53 abn is associated with increased recurrence, decreased survival, and benefitted from chemotherapy in the PORTEC-3 subgroup molecular analysis. The clinical trials PORTEC-4a and CANSTAMP will prospectively assess this. MMRd and NSMP groups have intermediate prognosis and will likely continue to rely closely on clinicopathological features for adjuvant treatment decisions. In addition, the molecular classification has led to exploring novel treatments such as checkpoint inhibitors. Overall, the molecular perspective on EC and associated clinical trials will likely refine EC risk stratification to optimize care and avoid overtreatment.
