O-RADS MRI SCORE: An Essential First-Step Tool for the Characterization of Adnexal Masses

The ovarian-adnexal reporting and data system on magnetic resonance imaging (O-RADS MRI) score is now a well-established tool to characterize pelvic gynecological masses based on their likelihood of malignancy. The main added value of O-RADS MRI over O-RADS US is to correctly reclassify lesions that were considered suspicious on US as benign on MRI. The crucial issue when characterizing an adnexal mass is to determine the presence/absence of solid tissue and thus need to perform gadolinium injection. O-RADS MR score was built on a multivariate analysis and must be applied as a step-by-step analysis: 1) Is the mass an adnexal mass? 2) Is there an associated peritoneal carcinomatosis? 3) Is there any significant amount of fatty content? 4) Is there any wall enhancement? 5) Is there any internal enhancement? 6) When an internal enhancement is detected, does the internal enhancement correspond to solid tissue or not? 7) Is the solid tissue malignant? With its high value to distinguish benign from malignant adnexal masses and its high reproducibility, the O-RADS MRI score could be a valuable tool for timely referral of a patient to an expert center for the treatment of ovarian cancers. Finally, to make a precise diagnosis allowing optimal personalized treatment, the radiologist in gynecological imaging will combine the O-RADS MRI score with many other clinical, biological, and other MR criteria to suggest a pathological hypothesis.

First-line surgery vs first-line ART to manage infertility in women with deep endometriosis without bowel involvement: A multi-centric propensity-score matching comparison

OBJECTIVE

To compare first-line surgery with first-line assisted reproductive techniques (ART) in infertile women with deep infiltrating endometriosis (DIE) without colorectal involvement.

STUDY DESIGN

A retrospective comparative cohort study with a propensity-score matching analysis, in four tertiary-care referral centers. The population was infertile women with DIE without colorectal involvement. The patients were managed either by first-line surgery followed by spontaneous conception attempts and/or ART, or by first-line ART. 284 patients were extracted from the databases. After matching, 92 patients were compared in each group. Clinical pregnancy rates (PR) and live-birth rates (LBR) were the primary outcomes, and cumulative pregnancy rate (CPR) and cumulative live birth rate (CLBR) were the secondary outcomes.

RESULTS

The mean number of IVF-ICSI cycles per patient was 1.4, with a significant difference between the groups: 1.6 in the first-line ART group and 1.2 in the first-line surgery group (p = 0.006). The PR was significantly higher in the first-line surgery group (72 % vs 35 %; p < 0.001). In the first-line surgery group, non-ART pregnancies occurred in 18 % (17/92) while no non-ART pregnancies was noted in the first-line ART group. The LBR was significantly higher in the first-line surgery group (61 % vs 24 %; p < 0.001). After ART, the CPR were 72 % (47/67) in the first-line surgery group, and 35 % (32/92) in the first-line ART group (p < 0.001).

CONCLUSION

After matching, our results support that first-line surgery offer higher pregnancy and live-birth rates than first-line ART in patients with DIE without colorectal involvement.

[Guidelines for Clinical Practice of the French College of Obstetricians and Gynecologists 2021: Prophylactic procedures associated with gynecologic surgery]

OBJECTIVE

To draw up recommendations on the use of prophylactic gynecologic procedures during surgery for other indications.

DESIGN

A consensus panel of 19 experts was convened. A formal conflict of interest policy was established at the onset of the process and applied throughout. The entire study was performed independently without funding from pharmaceutical companies or medical device manufacturers. The panel applied the GRADE (Grading of Recommendations Assessment, Development and Evaluation) system to evaluate the quality of evidence on which the recommendations were based. The authors were advised against making strong recommendations in the presence of low-quality evidence. Some recommendations were ungraded.

METHODS

The panel studied 22 key questions on seven prophylactic procedures: 1) salpingectomy, 2) fimbriectomy, 3) salpingo-oophorectomy, 4) ablation of peritoneal endometriosis, 5) adhesiolysis, 6) endometrial excision or ablation, and 7) cervical ablation.

RESULTS

The literature search and application of the GRADE system resulted in 34 recommendations. Six were supported by high-quality evidence (GRADE 1+/-) and 28 by low-quality evidence (GRADE 2+/-). Recommendations on two questions were left ungraded due to a lack of evidence in the literature.

CONCLUSIONS

A high level of consensus was achieved among the experts regarding the use of prophylactic gynecologic procedures. The ensuing recommendations should result in improved current practice.

Antenatal screening of small for gestational age: Impact on obstetrical management and neonatal outcomes in case of trial of labor after 37 weeks

OBJECTIVE

Antenatal screening of small fetuses for gestational age (SGA) is a public health challenge. The aim of this study is to assess the obstetrical management and the immediate neonatal outcomes, according to the antenatal screening of the SGA fetuses.

METHODS

We performed a retrospective study in a French tertiary care hospital between January 1, 2016 and December 31, 2018. Women were eligible if they had a monofetal pregnancy with a fetus in head presentation and a trial of labor after 37 weeks. A fetus was considered SGA when the estimated fetal weight was less than the 10^th percentile at the third trimester ultrasound. A newborn was considered hypotrophic when the birthweight was less than the 10th percentile.

RESULTS

8 153 newborns were included and 948 of the newborns were hypotrophic (308 were suspected for SGA, 640 were not suspected for SGA) and 7205 were eutrophic. Among the hypotrophic neonates, we observed no significant difference regarding the immediate neonatal outcomes between the two groups of fetuses suspected and not suspected for SGA. Among the fetuses not suspected for SGA, the rate of arterial umbilical cord pH below 7.10 was significantly higher in the hypotrophic newborns compared to the non hypotrophic newborns (4.7% vs 3.1%, p = 0.041).

CONCLUSION

In our population, unsuspected fetal hypotrophy may be associated with an increased risk of neonatal acidosis. These results emphasize the benefit of improving prenatal screening to identify the SGA fetuses.

How to predict para-aortic node involvement in advanced cervical cancer? Development of a predictive score. A FRANCOGYN study

INTRODUCTION

Node involvement is one of the main prognostic factors for cervical cancer. Para-aortic lymph node (PALN) assessment is crucial for treating advanced cervical cancer, to define irradiation fields. Objective of this study was to develop a score predicting para-aortic lymph node involvement in patients with advanced cervical cancer.

PATIENTS AND METHOD

We performed a multicenter, retrospective, study on 9 French centers from 2000 to 2015, including patients with advanced squamous cell cervix carcinoma who had PALN status assessed by imaging and/or by surgery. Factors associated with a risk of PALN involvement were determined by univariate and multivariate analysis using a logistic regression model. A score was then developed and validated.

RESULTS

A total of 1446 patients treated for cervical cancer were included. Of these, 498 had an advanced squamous cell cervical cancer. Ninety-one patients (18.3%) had positive PALN. After univariate and multivariate analysis, tumor size on pelvic MRI, initial SCC, and suspected pelvic node involvement on PET-CT were included in our score. This model allowed the population to be divided into 3 risk groups. Area under the ROC curve of the score was 0.81 (95%CI = 0.72-0.90). In the low-risk group, 9% (28/287) had PALN involvement, whereas in the high-risk group, 43% (22/51) had PALN involvement.

CONCLUSION

We developed a simple score predicting PALN involvement in advanced cervical cancers. Three risk groups can be defined, and patients considered to be at low risk may avoid para-aortic staging as well as extensive field irradiation.

Impact of COVID-19 on surgical emergencies: nationwide analysis

Background

The COVID-19 pandemic has had a major impact on healthcare in many countries. This study assessed the effect of a nationwide lockdown in France on admissions for acute surgical conditions and the subsequent impact on postoperative mortality.

Methods

This was an observational analytical study, evaluating data from a national discharge database that collected all discharge reports from any hospital in France. All adult patients admitted through the emergency department and requiring a surgical treatment between 17 March and 11 May 2020, and the equivalent period in 2019 were included. The primary outcome was the change in number of hospital admissions for acute surgical conditions. Mortality was assessed in the matched population, and stratified by region.

Results

During the lockdown period, 57 589 consecutive patients were admitted for acute surgical conditions, representing a decrease of 20.9 per cent compared with the 2019 cohort. Significant differences between regions were observed: the decrease was 15.6, 17.2, and 26.8 per cent for low-, intermediate- and high-prevalence regions respectively. The mortality rate was 1.92 per cent during the lockdown period and 1.81 per cent in 2019. In high-prevalence zones, mortality was significantly increased (odds ratio 1.22, 95 per cent c.i. 1.06 to 1.40).

Conclusion

A marked decrease in hospital admissions for surgical emergencies was observed during the lockdown period, with increased mortality in regions with a higher prevalence of COVID-19 infection. Health authorities should use these findings to preserve quality of care and deliver appropriate messages to the population.

Management of borderline ovarian tumours during pregnancy: Results of a French multi-centre study

OBJECTIVE

To assess the diagnostic and prognostic characteristics of borderline ovarian tumours (BOTs) detected during pregnancy, and to establish an inventory of French practices.

MATERIALS AND METHODS

A retrospective multi-centre case study of 14 patients treated for BOTs, diagnosed during pregnancy between 2005 and 2017, in five French pelvic cancerology expert centres, including data on clinical characteristics, histological tumour characteristics, surgical procedure, adjuvant treatments, follow-up and fertility.

RESULTS

The mean age of patients was 29.3 [standard deviation (SD) 6.2] years. Most BOTs were diagnosed on ultrasonography in the first trimester (85.7 %), and most of these cases (78.5 %) also underwent magnetic resonance imaging to confirm the diagnosis (true positives 54.5 %). Most patients underwent surgery during pregnancy (57 %), with complete staging surgery in two cases (14.3 %). Laparoscopy was performed more frequently than other procedures (50 %), and unilateral adnexectomy was more common than cystectomy (57.5 %). Tumour size influenced the surgical approach significantly (mean size 7.5 cm for laparoscopy, 11.9 cm for laparoconversion, 14 cm for primary laparotomy; P = 0.08), but the type of resection did not. Most patients were initially diagnosed with International Federation of Gynecology and Obstetrics stage IA (92.8 %) tumours, but many were upstaged after complete restaging surgery (57.1 %). Most BOTs were serous (50 %), two cases had a micropapillary component (28.5 %), and one case had a micro-invasive implant. BOTs were bilateral in two cases (14.2 %). Mean follow-up was 31.4 (SD 14.8) months. Recurrent lesions occurred in two patients (14.2 %) and no deaths have been recorded to date among the study population.

CONCLUSION

BOTs remain rare, but this study - despite its small sample size - supports the hypothesis that BOTs during pregnancy have potentially aggressive characteristics.

Recurrence Pattern of Cervical Cancer Based on the Platinum Sensitivity Concept: A Multi-Institutional Study from the FRANCOGYN Group

The standard of care for patients with advanced cervical cancer (ACC) includes platinum-based chemotherapy. The concept of platinum sensitivity is a major prognostic factor for patients with ovarian cancer. The aim of this study was to validate the applicability of the platinum sensitivity concept to ACC patients, and to estimate its prognostic interest in terms of overall survival (OS) and pattern of recurrence (location, timing). Data of women with histologically proven FIGO 2019 stages IB3-IV ACC, treated between May 2000 and November 2017 with platinum-based regimens, were retrospectively abstracted from 12 institutions from the FRANCOGYN Group. Respective 3-year OSs were 52% (95% CI: 40.8%-66.8%), 21.6% (95% CI: 12.6%-37.2%), and 14.6% (95% CI: 4.2%-50.2%), in case of recurrence <6 months, between 6 and 17 months, and ≥18 months (p < 0.001). Risk of metastatic or multisite recurrence was significantly higher in case of recurrence <6 months, and risk of local or isolated infradiaphragmatic nodal recurrence was significantly higher in case of recurrence >18 months (p < 0.001). In multivariate analysis, platinum sensitivity status was a strong prognostic factor for OS after recurrence, independent of histological grade, lympho-vascular space involvement, final lymph node status, and treatment. Platinum sensitivity status may help to classify patients in three prognostic subgroups for OS after recurrence, and appears to be a strong prognostic factor correlated to the pattern of recurrence.

[Guidelines for surgical management of gynaecological cancer during pandemic COVID-19 period - FRANCOGYN group for the CNGOF]

INTRODUCTION

Recommendations for the management of patients with gynecological cancer during the COVID-19 pandemic period.

MATERIAL AND METHOD

Recommendations based on the consensus conference model.

RESULTS

In the case of a COVID-19 positive patient, surgical management should be postponed for at least 15 days. For cervical cancer, the place of surgery must be re-evaluated in relation to radiotherapy and Radio-Chemotherapy-Concomitant and the value of lymph node staging surgeries must be reviewed on a case-by-case basis. For advanced ovarian cancers, neo-adjuvant chemotherapy should be favored even if primary cytoreduction surgery could be envisaged. It is lawful not to offer hyperthermic intraperitoneal chemotherapy during a COVID-19 pandemic. In the case of patients who must undergo interval surgery, it is possible to continue the chemotherapy and to offer surgery after 6 cycles of chemotherapy. For early stage endometrial cancer, in case of low and intermediate preoperative ESMO risk, hysterectomy with bilateral annexectomy associated with a sentinel lymph node procedure should be favored. It is possible to consider postponing surgery for 1 to 2 months in low-risk endometrial cancers (FIGO Ia stage on MRI and grade 1-2 endometrioid cancer on endometrial biopsy). For high ESMO risk, it ispossible to favor the MSKCC algorithm (combining PET-CT and sentinel lymph node biopsy) in order to omit pelvic and lumbar-aortic lymphadenectomies.

CONCLUSION

During COVID-19 pandemic, patients suffering from cancer should not lose life chance, while limiting the risks associated with the virus.

Postoperative evaluation of chronic pain in patients with Mayer - Rokitansky - Küster - Hauser (MRKH) syndrome and uterine horn remnant: Experience of a tertiary referring gynaecological department

INTRODUCTION

Patients with Mayer - Rokitansky - Küster - Hauser (MRKH) syndrome often experience chronic pelvic pain negatively impacting their life's quality. Our understanding of the factors involved in this symptom remains poor. The aim of our study was to further investigate the different components of this pelvic pain in patients with MRKH undergoing pelvic surgery. Our second objective was to assess the evolution of this pain in patients undergoing surgical removal of their uterine horn remnant.

MATERIAL AND METHODS

We conducted a retrospective analysis of a cohort of patients treated in our tertiary referring gynaecological department. Patients included had a MRKH syndrome with at least one uterine horn remnant and all underwent at least one surgical procedure in our centre. Descriptive analysis of the main characteristics and of the management of these patients was conducted. Postoperative pain was evaluated using simple words and / or analgesic consumption evaluation.

RESULTS

Between 1991 and 2013, twenty-one patients were included in our centre. Out of them, 20 (95 %) had chronic pelvic pain, mostly cyclic pain lasting 2-3 days. Fourteen patients had surgical removal of their uterine horns remnant and only 3 patients (21 %) had persistent pain at their postoperative visit. Surgical findings included peritoneal endometriosis in 8 patients (38 %) and other unexpected findings in 6. At pathological analysis, secretary endometrium in the uterine horn remnant was found in 11 patients (79 %).

CONCLUSION

The origin of chronic pain in MRKH is combining several factors such as endometriosis or secretary endometrium. Surgical removal of uterine horn remnant improved most of our patients' pelvic chronic pain. Further studies should help improve our understanding of this specific entity.

Fertility and pregnancy outcomes in patients with bicorporeal uterus and blind hemivagina: 20 years of experience in a tertiary referral gynaecological department

BACKGROUND

To evaluate fertility and pregnancy outcomes in patients with uterus bicorporeal and blind hemivagina. Our second objective was to investigate factors predicting fertility and pregnancy outcomes in those patients.

MATERIAL AND METHODS

We conducted a retrospective analysis in a tertiary referring gynaecological department, in France. We included all patients with uterus bicorporeal and blind hemivagina who underwent at least one surgery in our centre. Initial characteristics of the patients included were extracted from their medical charts and patients were contacted to assess their fertility and pregnancies outcomes upon their consent to participate to the study.

RESULTS

Between 1989 and 2010, 79 patients fulfilled inclusion criteria and were selected for analysis. Mean follow up of those patients was of 16.15 (QI 10-21) years. Forty-six patients (58.2%) returned the survey and among them, 21 (45.7%) were fertile, 8 (17.4%) were infertile and 17 (37%) never attempted to get pregnant following initial management. Forty-nine pregnancies were included to assess pregnancies outcomes: 11 (22.5%) early miscarriages, 1 (2.0%) extra-uterine pregnancy, 2 (4.1%) second semester miscarriages and 35 (71.4%) leaded to living birth. Nineteen (54.3%) deliveries occurred by caesarean section and 14 (40.0%) by vaginal delivery. Fifteen pregnancies (42.9%) were complicated. In univariate analysis, adhesiolysis performed at the time of initial surgery was the only factor associated with infertility (p=0.004).

CONCLUSIONS

Fertility seems to be perfectly conserved in those patients and they do not have increased rate of adverse pregnancies outcomes.

[Negative prognostic impact of female gender on oncological outcomes following radical cystectomy]

OBJECTIVE

To confirm gender specific differences in pathologic factors and survival rates of urothelial bladder cancer patients treated with radical cystectomy.

PATIENTS AND METHODS

We conducted a retrospective monocentric study on 701 patients treated with radical cystectomy and pelvic lymphadenectomy for muscle invasive bladder cancer. Impact of gender on recurrence rate, specific and non-specific mortality rate were evaluated using Cox regression models in univariate and multivariate analysis.

RESULTS

We collected data on 553 males (78.9%) and 148 females (21.1%) between 1998 and 2011. Both groups were comparable at inclusion regarding age, pathologic stage, nodal status and lymphovascular invasion. Mean follow-up time was 45 months (interquartile 23-73) and by that time, 163 patients (23.3%) had recurrence of their tumor and 127 (18.1%) died from their disease. In multivariable Cox regression analyses, female gender was independently associated with disease recurrence (RR: 1.73; 95% CI 1.22-2.47; P=0.02) and cancer-specific mortality (RR=2.50, 95% CI=1.71-3.68; P<0.001).

CONCLUSION

We confirmed female gender to be an independent negative prognosis factor for patients following a radical cystectomy and lymphadenectomy for an invasive muscle bladder cancer.
