Evaluating the safety of high-intensity focused ultrasound treatment for rectal endometriosis: results from a French prospective multicentre study including 60 patients.

STUDY QUESTION: Is increasing the intensity of high-intensity focused ultrasound (HIFU) by 30% in the treatment of rectal endometriosis a safe procedure? SUMMARY ANSWER: This study demonstrates the safety of a 30% increase in the intensity of HIFU in the treatment of rectal endometriosis, with no Clavien-Dindo Grade III complications overall, and namely no rectovaginal fistulae. WHAT IS KNOWN ALREADY: A feasibility study including 20 patients with rectal endometriosis demonstrated, with no severe complications, a significant improvement in digestive disorders, dysmenorrhoea, dyspareunia, and health status, although the volume of the endometriosis nodule did not appear to be reduced. STUDY DESIGN, SIZE, DURATION: A prospective multicentre cohort study was conducted between 2020 and 2022 with 60 patients with symptomatic rectal endometriosis. Following the failure of medical treatment, HIFU treatment was offered as an alternative to surgery. PARTICIPANTS/MATERIALS, SETTING, METHODS: As the main objective of this study was to examine safety, all adverse events observed during the 6 months of follow-up were analysed and graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE) and Clavien-Dindo classifications. Secondary objectives included evaluating the evolution of symptoms using validated questionnaires: gynaecological and digestive pain symptoms with a visual analogue scale, health status with the Medical Outcomes Study 36-item Short Form (SF-36) questionnaire, average post-operative daily pain level, and analgesic medication required in the 10 days following treatment. MRI was also performed at Day 1 to detect early complications. Finally, we performed a blinded MRI review of the evolution of the nodule at 6 months post-treatment. MAIN RESULTS AND THE ROLE OF CHANCE: The procedure was performed under spinal anaesthesia for 30% of the patients. The median duration of treatment was 32 min. Fifty-five patients left the hospital on Day 1. MRI scans performed on Day 1 did not highlight any early-onset post-operative complication. Using the Clavien-Dindo classification, we listed 56.7% Grade I events, 3.4% Grade II events, and no events Grade III or higher. At 1, 3, and 6 months, all gynaecologic, digestive and general symptoms, as well as health status, had significantly improved. The evolution of the nodule was also significant (P < 0.001) with a 28% decrease in volume. LIMITATIONS, REASONS FOR CAUTION: The main objective was safety and not effectiveness. The study was not randomized and there was no control group. WIDER IMPLICATIONS OF THE FINDINGS: HIFU treatment for rectal endometriosis results in an improvement of symptoms with low morbidity; as such, for selected patients, it could be a valuable alternative to surgical approaches following the failure of medical treatment. STUDY FUNDING/COMPETING INTEREST(S): The study was funded by the company EDAP TMS. Professors Dubernard and Rousset are consultants for EDAP TMS. Dubernard received travel support from EDAP-TMS. Dr F. Chavrier received industrial grants from EDAP-TMS. He has developed a device for generating focused ultrasonic waves with reduced treatment time. This device has been patented by EDAP-TMS. Dr Lafon received industrial grants from EDAP-TMS; he declares that EDAP-TMS provided funding directly to INSERM to support a young researcher chair in therapeutic ultrasound, which is unrelated to the current study.

Transrectal high-intensity focused ultrasound (HIFU) for management of rectosigmoid deep infiltrating endometriosis: results of Phase-I clinical trial.

OBJECTIVES: Deep infiltrating endometriosis (DIE) of the rectosigmoid is associated with painful symptoms. When medical treatment is ineffective, surgical resection remains the standard treatment, despite significant risk of adverse events. High-intensity focused ultrasound (HIFU) is a minimally invasive ablative procedure. Focal One® is a transrectal HIFU (TR-HIFU) device used in prostate cancer treatment. The primary objective of this study was to confirm the feasibility of treatment with TR-HIFU in patients presenting with posterior DIE with rectosigmoid involvement. We also assessed its safety and clinical efficacy in this context. METHODS: This was a non-controlled, prospective, Phase-I clinical trial in a French University Hospital which is a multidisciplinary center for management of endometriosis. Included were patients older than 25 years, without plans to conceive within 6 months, who presented with a single lesion of posterior DIE, with rectosigmoid invasion, after failure of hormonal therapy. All lesions were assessed preoperatively using transvaginal sonography and magnetic resonance imaging. Patients completed questionnaires on gynecological and intestinal symptoms (similar to a visual analog scale (VAS)), and on quality of life (Medical Outcomes Study 36-item short-form survey (SF-36) and, for the second half of patients recruited, symptom scoring system for constipation (KESS), female sexual function index (FSFI) and endometriosis health profile short-version score (EHP-5)), before, and at 1, 3 and 6 months after, TR-HIFU treatment with a Focal One real-time ultrasound-guided HIFU device. RESULTS: Twenty-three consecutive patients were included in the study between September 2015 and October 2019. All 23 lesions were visualized, giving a detection rate of 100%. Twenty lesions were treated ('feasibility rate', 87.0%): in 13 the whole lesion was treated and in seven the lesion was treated partially. The mean duration of the TR-HIFU procedure was 55.6 min. We observed a significant improvement in VAS score at 6 months, with differences relative to preoperative scores as follows, for: dysmenorrhea (-3.6, P = 0.004), dyspareunia (-2.4, P = 0.006), diarrhea (-3.0, P = 0.006), constipation (-3.0, P = 0.002), dyschezia (-3.2, P = 0.003), false urge to defecate (-3.3, P = 0.007), posterior pelvic pain (-3.8, P = 0.002) and asthenia (-3.8, P = 0.002). There was also a significant improvement in the SF-36 score, with an increase at 6 months relative to the preoperative score in both the physical component summary (+ 9.3%, P = 0.002) and mental component summary (+ 10.9%, P = 0.017). No major complications occurred during or after any procedure. CONCLUSIONS: TR-HIFU therapy for posterior DIE is feasible. If its efficacy and safety are confirmed, it could be a minimally invasive alternative to surgery for the treatment of rectosigmoid endometriosis. © 2019 Authors.

Contribution of Lymphoscintigraphy for Sentinel Lymph Node Biopsy in Women with Early Stage Endometrial Cancer: Results of the SENTI-ENDO Study.

BACKGROUND: This study was designed to evaluate detection rate and anatomical location of sentinel lymph node (SLN) at lymphoscintigraphy, to compare short and long lymphoscintigraphy protocols, and to correlate lymphoscintigraphic and surgical mapping of SLN in patients with early-stage endometrial cancer (EC). METHODS: Subanalysis of the prospective multicenter study Senti-endo performed from July 2007 to August 2009. Patients with stage I and II EC received four cervical injections of 0-2 mL of unfiltered technetium sulphur colloid the day before (long protocol) or the morning (short protocol) before surgery. SLN detection used a combined technetium/patent blue labeling technique, and all patients had a systematic bilateral pelvic lymphadenectomy. RESULTS: A total of 133 patients were enrolled in the study and 118 (94.5 %) underwent a lymphoscintigraphy. Of these 118 patients, 44 (37 %) underwent a short protocol and 66 (56 %) a long protocol (data on lymphoscintigraphy were not available in eight patients). Lymphoscintigraphic detection rate was 74.6 % (34 % for short protocol and 60.2 % for long protocol). No difference in the detection rate was observed according to lymphoscintigraphy protocol (p = 0.22), but a higher number of SLN was noted for the long protocol (p = 0.02). Aberrant drainage was noted on lymphoscintigraphy in 30.5 % of the patients. Paraaortic SLNs were exclusively detected using the long protocol. A poor correlation was noted between short (κ test = 0.24) or long lymphoscintigraphy (κ test = 0.3) protocol and SLN surgical mapping. CONCLUSIONS: Our study demonstrates that preoperative lymphoscintigraphy allowed a high SLN detection rate and that long lymphoscintigraphy protocol was associated with a higher detection of aberrant drainage especially in the paraaortic area.

Accuracy of a nomogram for prediction of lymph-node metastasis detected with conventional histopathology and ultrastaging in endometrial cancer.

BACKGROUND: We developed a nomogram based on five clinical and pathological characteristics to predict lymph-node (LN) metastasis with a high concordance probability in endometrial cancer. Sentinel LN (SLN) biopsy has been suggested as a compromise between systematic lymphadenectomy and no dissection in patients with low-risk endometrial cancer. METHODS: Patients with stage I-II endometrial cancer had pelvic SLN and systematic pelvic-node dissection. All LNs were histopathologically examined, and the SLNs were examined by immunohistochemistry. We compared the accuracy of the nomogram at predicting LN detected with conventional histopathology (macrometastasis) and ultrastaging procedure using SLN (micrometastasis). RESULTS: Thirty-eight of the 187 patients (20%) had pelvic LN metastases, 20 had macrometastases and 18 had micrometastases. For the prediction of macrometastases, the nomogram showed good discrimination, with an area under the receiver operating characteristic curve (AUC) of 0.76, and was well calibrated (average error =2.1%). For the prediction of micro- and macrometastases, the nomogram showed poorer discrimination, with an AUC of 0.67, and was less well calibrated (average error =10.9%). CONCLUSION: Our nomogram is accurate at predicting LN macrometastases but less accurate at predicting micrometastases. Our results suggest that micrometastases are an 'intermediate state' between disease-free LN and macrometastasis.

Management of women with abnormal uterine bleeding: Clinical practice guidelines of the French National College of Gynaecologists and Obstetricians (CNGOF).

OBJECTIVE: To provide French guidelines for the management of women with abnormal uterine bleeding (AUB). DESIGN: A consensus committee of 26 experts was formed. A formal conflict-of-interest policy was developed at the beginning of the process and enforced throughout. The entire guidelines process was conducted independently of any industry funding (i.e. pharmaceutical or medical device companies). The authors were advised to follow the rules of the Grading of Recommendations Assessment, Development and Evaluation (GRADE®) system to guide assessment of quality of evidence. The potential drawbacks of making strong recommendations in the presence of low-quality evidence were emphasized. METHODS: The last guidelines from the Collège National des Gynécologues et Obstétriciens Français on the management of women with AUB were published in 2008. The literature seems now sufficient for an update. The committee studied questions within 7 fields (diagnosis; adolescents; idiopathic AUB; endometrial hyperplasia and polyps; type 0-2 fibroids; type 3 or higher fibroids; and adenomyosis). Each question was formulated in a PICO (Patients, Intervention, Comparison, Outcome) format and evidence profiles were compiled. The GRADE® methodology was applied to the literature review and the formulation of recommendations. RESULTS: The experts' synthesis work and the application of the GRADE method resulted in 36 recommendations. Among the formalized recommendations, 19 are strong and 17 weak. No response was found in the literature for 14 questions. We chose to abstain from recommendations rather than providing advice based solely on expert clinical experience. CONCLUSIONS: The 36 recommendations make it possible to specify the diagnostic and therapeutic strategies for various clinical situations practitioners encounter, from the simplest to the most complex.

The role of lymph node resection in ovarian cancer: analysis of the Surveillance, Epidemiology, and End Results (SEER) database.

OBJECTIVE: The therapeutic role of lymphadenectomy on the survival in patients with ovarian cancer is controversial. The aim of this study was to evaluate the survival impact of lymphadenectomy, depending on the disease stage and extent of the surgery. DESIGN: The surveillance, epidemiology, and end results (SEER) registry provided ovarian cancer data from 17 registries. SETTING: Surveillance, Epidemiology, and End Results database. POPULATION: The study population comprised 49,783 patients. METHODS: Survival was studied according to the number of lymph nodes removed, with stratifications on disease stage and extent of surgery. MAIN OUTCOME MEASURE: The 5-year cause-specific survival rate. RESULTS: The median follow up for patients alive at the last follow-up visit was 39 months. The five-year cause-specific survival rates were 37, 62, and 71% for the groups in which no lymph nodes were examined, in which between one and nine nodes were examined, and in which ten or more nodes were examined, respectively (P< 0.001). Avoiding lymphadenectomy was deleterious in all stages of the disease. It was maximal for International Federation of Gynecology and Obstetrics (FIGO) stage-II patients, but there was no significant interaction between stage and extent of lymphadenectomy. The cause-specific survival was found to significantly increase when more nodes were resected, even if the surgical procedure consisted of debulking surgery or a pelvic exenteration. CONCLUSION: Our study suggests a beneficial effect of lymphadenectomy in epithelial ovarian tumours, regardless of the stage of disease and extent of surgery. However, potential biases inherent to this retrospective methodology, such as staging migration, defining the extent of residual disease, and the possibility that thorough lymphadenectomy may reflect the quality of cytoreductive surgery, preclude any formal conclusions on the therapeutic role of lymphadenectomy.

[Impact of the COVID-19 Outbreak on the management of patients with gynecological cancers]. / Impact de la pandémie de Covid-19 sur les modifications thérapeutiques des patientes atteintes de cancers gynécologiques.

OBJECTIVE: The exceptional health situation related to the SARS-Cov2 coronavirus pandemic (COVID-19) required a deep and very quickly adaptation of management practices in gynecological cancer. The main objective is to estimate the proportion of patients with treatment modifications. METHOD: This is a multicenter prospective study conducted in 3 university gynecological cancer departments (HCLyon, France) during the period of confinement (March 16 to May 11, 2020). All patients with non-metastatic breast cancer or gynecological cancer were included. The planned treatment, postponement, delay and organizational modifications (RCP, teleconsultations) were studied. RESULTS: Two hundred and five consecutive patients were included, average age 60.5±1.0. 7 patients (3.4%) had SARS-Cov-2 infection, 2 patients died. One hundred and twenty-two patients (59.5%) had a treatment maintained, 72 patients (35.1%) postponed, 11 patients (5.4%) cancelled. Of the 115 (56.1%) planned surgeries, 40 (34.8%) postponed, 7 cancelled (6.1%). 9 patients (7.8%) had a surgical modification. Of the 59 (28.8%) radiotherapy treatments scheduled, 24 (40.7%) postponed and 2 (3.4%) cancelled. Of the 56 (27.3%) chemotherapy treatment planned, 8 (14.3%) postponed and 2 (3.6%) cancelled. One hundred and forty-five patients (70.7%) have been discussed in multidisciplinary meeting. One hundred and fifty-eight patients (77%) had a teleconsultation system. CONCLUSION: Our study assessed the impact of the COVID-19 pandemic on therapeutic management of patients with gynecological cancer during the period of confinement. This will probably improve our management of an eventual epidemic rebound or future health crisis.

Surgical activity during the Covid-19 pandemic: Results for 112 patients in a French tertiary care center, a quality improvement study.

BACKGROUND: After the emergence of Covid-19 in China, Hubei Province, the epidemic quickly spread to Europe. France was quickly hit and our institution was one of the first French university to receive patients infected with Sars-COV2. The predicted massive influx of patients motivated the cancellation of all elective surgical procedures planned to free hospitalization beds and to free intensive care beds. Nevertheless, we should properly select patients who will be canceled to avoid life-threatening. The retained surgical indications are surgical emergencies, oncologic surgery, and organ transplantation. MATERIAL AND METHODS: We describe the organization of our institution which allows the continuation of these surgical activities while limiting the exposure of our patients to the Sars Cov2. RESULTS: After 4 weeks of implementation of intra-hospital protocols for the control of the Covid-19 epidemic, 112 patients were operated on (104 oncology or emergency surgeries and 8 liver transplants). Only one case of post-operative contamination was observed. No mortality related to Covid-19 was noted. No cases of contamination of surgical care personnel have been reported. CONCLUSION: We found that the performance of oncological or emergency surgery is possible, safe for both patients and caregivers.

[Relevance of quality of life questionnaires in women with endometriosis]. / Intérêt des questionnaires de qualité de vie chez les patientes porteuses d'une endométriose.

High recurrence rates have been reported in women treated for endometriosis despite advances in medical and surgical treatments improving both fertility and symptoms. It should therefore be considered a chronic disorder. In this particular setting, the main objectives for practitioners are to limit disease progression, recurrence and to improve quality of life (QOL). Previous studies have demonstrated a relation between an increase in pain intensity and a decrease in QOL. However, visual analogue scales to measure general well-being are insufficient to quantify the impact of endometriosis on QOL. Several generic questionnaires, mainly the SF-36, are available in various languages but are not specific of women with endometriosis. Some specific questionnaires are available but have been validated in English population for the most part rending comparison between countries difficult. Despite these limits, QOL should be systematically monitored over time by a validated questionnaire for this chronic disorder and could be a criterion for therapeutic strategy.

[Management of puerperal hematomas]. / Prise en charge des hématomes puerpéraux.

Puerperal hematoma is a rare complication of the postpartum period remaining imperfectly known. We present an update of knowledge on this particular type of puerperal haemorrhage threatening in some cases maternal prognosis. In vulvovaginal hematomas, the diagnosis relies on clinical findings whereas it requires medical imaging in the retroperitoneal localisations. Therapeutic approach also largely differs according to the localisation of the hematoma. We thus propose a synthesis of the critical care strategies depending on the type of the puerperal hematoma.

[Color-codes implementation shortens the decision-to-delivery interval of emergency C-sections]. / La mise en oeuvre des codes "couleur" réduit le délai décision-naissance des césariennes urgentes.

OBJECTIVES: To assess the efficiency of a new tool designed to shorten the decision-to-delivery interval (DDI) for emergency C-sections (CS). MATERIALS AND METHODS: DDI comparisons during three 6-month periods in a third level maternity. In stage A we evaluated the spontaneous DDI, in stage B the DDI was measured after the introduction of a color-code communication tool related to the degree of urgency for CS (amber code indicated urgent CS with an ideal DDI of 30 min and red code for very urgent CS with an ideal DDI of 15 min). In stage C we assessed the impact of the color-codes related protocols implementation. RESULTS: Two hundred and fifty-three C-sections were included (211 urgent CS and 42 very urgent CS). Mean DDI decreased significantly from 42 min to 24 min between period A and period C for amber codes (corresponding to 43.2% and 82.1% of the objectives respectively) and from 24.9 min to 10.7 min for red codes (20% et 83.3% of the objectives). CONCLUSION: This study suggests that color-codes and their related application protocols significantly shorten the DDI during the evaluation periods.

Use of the SF-36 questionnaire to predict quality-of-life improvement after laparoscopic colorectal resection for endometriosis.

BACKGROUND: Laparoscopic colorectal resection for endometriosis can improve quality of life (QOL), but the results vary widely from one woman to another. The aim of this study was to determine whether the preoperative results on the Physical Component Summary (PCS) and Mental Component Summary (MCS) subscales of the SF-36 questionnaire could predict the improvement in QOL after surgery. METHODS: The predictive value of the subscales was first evaluated on a training set of 57 patients. A mathematical model, quantified with respect to discrimination and calibration was then applied to the validation set of 36 patients. RESULTS: Women with preoperative PCS and MCS scores below 37.5 and 44.5, respectively, had 80.7% and 84.2% probabilities of seeing their scores improve after surgery, whereas women with preoperative scores above 46.5 and 47.5, respectively, had probabilities of 0% and 10.7% to improve their scores. CONCLUSIONS: With our mathematical model, the postoperative improvement in QOL can be reliably predicted. This model should help to identify those women who are most likely to benefit from this major surgery.

[Imaging in pelvic inflammatory disease]. / Imagerie de l'infection pelvienne.

This is a review of evolutive aspects in pelvic inflammatory disease (salpingitis, endometritis, pyosalpinx, tubo ovarian abscess) assessed by different imaging modalities (Ultrasound, CT, MRI and hysterosalpingography).

[Risk of breast cancer related to pregnancy]. / Risque de cancer du sein lié à la grossesse.

After a pregnancy, there is a transitory increase in the risk of breast cancer. During the pregnancy, the number of mammary epithelial cells increases massively. This increase seems partly due to the expansion of stem cells and proliferating intermediate cells. This proliferation of epithelial cells is accompanied by angiogenesis and by recruitment of stromal cells, as well as changes of the extracellular matrix. During any pregnancy, there is cell trafficking between mother and foetus. Hematopoietic or mesenchymal foetal stem cells are transferred in maternal circulation and could be used by the tumor as support cells and take part in the tumoral development. The study of the mechanisms of this specific oncogenesis may help to develop chemoprevention strategies.

[Performances and place of sonography in the diagnostic of endometriosis: CNGOF-HAS Endometriosis Guidelines]. / Performances et place de l'échographie dans le diagnostic de l'endométriose, RPC Endométriose CNGOF­HAS.

Endometriosis is difficult to diagnose clinically. Transvaginal sonography (TVS) is a procedure that is known to be operator-dependent, which mean that published evidences has to be balanced with the level of the sonographer that produced the data. The objective of this publication was to assess the performances of the sonography in the diagnosis of endometriosis in order to establish the French national recommendations. We searched the MEDLINE database for publication from January 2000 to September 2017 using keywords associated with endometriosis and sonography. Eighty-four trial and reviews published in English or French were included. Ovarian endometrioma can usually be diagnosed by a non-expert sonographer, especially when its aspect is typical. In case of an ovarian cyst with atypical presentation, it is recommended to control the sonography by a referent or to perform an MRI. In menopaused women, any ovarian cyst should be considered as a cancer until proven otherwise. In the diagnosis of posterior deep invasive endometriosis (DIE), TVS with sensitivity and specificity of 96 and 99% respectively, seems at least equivalent if not superior to MRI. However, these performances are related to expert sonographers. To reach sufficient efficiency in posterior DIE, the estimated learning curve for a sonographer is 44 cases. When posterior DIE is suspected, we recommend proposing a TVS "performed by an expert" or a MRI "at least interpreted by an expert". In anterior DIE, TVS has a good specificity (100%), but its sensitivity is poor in the literature (64%). TVS is therefore not able to eliminate the diagnosis. However a renal ultrasound should be proposed each time a urinary endometriosis is confirmed, and should be considered whenever posterior DIE is diagnosed especially the lesion is superior to 3cm.

Pregnancy and delivery after complete uterine rupture.

INTRODUCTION: To assess the obstetric outcome of pregnancies occurring after a complete uterine rupture. METHODS: Descriptive study of a series of 11 pregnancies after complete uterine rupture. RESULTS: This study includes 10 women with 11 pregnancies. There were no recurrences of complete uterine rupture. All women had cesarean deliveries between 32 and 37 weeks' gestation. There were no cases of either severe hemorrhage or placenta accreta and no maternal or neonatal deaths. All women had close clinical and ultrasound monitoring and were hospitalized during the third trimester. CONCLUSION: Women with a history of complete uterine rupture can have a subsequent pregnancy with a thoroughly favorable outcome with appropriate care conditions, including prophylactic caesarean section.

[Management of endometriosis: CNGOF-HAS practice guidelines (short version)]. / Prise en charge de l'endométriose : recommandations pour la pratique clinique CNGOF-HAS (texte court).

First-line investigations to diagnose endometriosis are clinical examination and pelvic ultrasound. Second-line investigations include pelvic examination performed by a referent clinician, transvaginal ultrasound performed by a referent echographist, and pelvic MRI. It is recommended to treat endometriosis when it is symptomatic. First-line hormonal treatments recommended for the management of painful endometriosis are combined with hormonal contraceptives or levonorgestrel 52mg IUD. There is no evidence to recommend systematic preoperative hormonal therapy for the unique purpose of preventing the risk of surgical complications or facilitating surgery. After endometriosis surgery, combined hormonal contraceptives or levonorgestrel SIU 52mg are recommended as first-line therapy in the absence of desire of pregnancy. In case of initial treatment failure, recurrence, or multiple organ involvement by endometriosis, medico-surgical and multidisciplinary discussion is recommended. The laparoscopic approach is recommended for the surgical treatment of endometriosis. HRT may be offered in postmenopausal women operated for endometriosis. In case of infertility related to endometriosis, it is not recommended to prescribe anti-gonadotropic hormone therapy to increase the rate of spontaneous pregnancy, including postoperatively. The possibilities of fertility preservation should be discussed with the patient in case of surgery for ovarian endometrioma.
