[Benefit-risk balance of hormone replacement therapy: Cancers and mortality. Postmenopausal women management - CNGOF and GEMVi clinical practice guidelines]. / La balance bénéfice­risque du traitement hormonal de la ménopause : cancers et mortalité. RPC Les femmes ménopausées CNGOF ­ GEMVi.

The use of hormone replacement therapy (HRT) for menopausal women has been the subject of much controversy in recent years, particularly concerning the carcinologic risks. The purpose of this review is to evaluate the impact of the use of HRT on the risk of gynecological but also extra-gynecological cancers. The effect of the type and the duration of use of HRT in menopausal women will also be discussed. The beneficial impact of HRT on overall mortality is also an element that will be discussed and must be taken into account when evaluating the benefit-risk balance of HRT for menopausal women.

Need for risk-adapted therapy for malignant ovarian germ cell tumors: A large multicenter analysis of germ cell tumors' patients from French TMRG network.

BACKGROUND: Malignant ovarian germ cell tumors are rare tumors, affecting young women with a generally favorable prognosis. The French reference network for Rare Malignant Gynecological Tumors (TMRG) aims to improve their management. The purpose of this study is to report clinicopathological features and long-term outcomes, to explore prognostic parameters and to help in considering adjuvant strategy for stage I patients. PATIENTS AND METHODS: Data from patients with MOGCT registered among 13 of the largest centers of the TMRG network were analyzed. We report clinicopathological features, estimated 5-year event-free survival (5y-EFS) and 5-year overall survival (5y-OS) of MOGCT patients. RESULTS: We collected data from 147 patients including 101 (68.7%) FIGO stage I patients. Histology identifies 40 dysgerminomas, 52 immature teratomas, 32 yolk sac tumors, 2 choriocarcinomas and 21 mixed tumors. Surgery was performed in 140 (95.2%) patients and 106 (72.1%) received first line chemotherapy. Twenty-two stage I patients did not receive chemotherapy. Relapse occurred in 24 patients: 13 were exclusively treated with upfront surgery and 11 received surgery and chemotherapy. 5y-EFS was 82% and 5y-OS was 92.4%. Stage I patients who underwent surgery alone had an estimated 5y-EFS of 54.6% and patients receiving adjuvant chemotherapy 94.4% (P < .001). However, no impact on estimated 5y-OS was observed: 96.3% versus 97.8% respectively (P = .62). FIGO stage, complete primary surgery and post-operative alpha fetoprotein level significantly correlated with survival. CONCLUSION: Adjuvant chemotherapy does not seem to improve survival in stage I patients. Active surveillance can be proposed for selected patients with a complete surgical staging.

Should We Abandon Systematic Pelvic and Paraaortic Lymphadenectomy in Low-Grade Serous Ovarian Cancer?

BACKGROUND: Low-grade serous ovarian carcinoma (LGSOC) is a rare disease that accounts for 5% of all ovarian cancers and requires surgical complete debulking. To date, the prognostic value of pelvic and paraaortic lymphadenectomy remains unclear in this population. PATIENTS AND METHODS: This retrospective cohort of patients with a diagnosis of LGSOC was registered in the Tumeurs Malignes Rares Gynécologiques national network, between January 2000 and July 2017, at 25 centers. All LGSOC were confirmed after pathological review and operated by primary debulking surgery (PDS) or interval debulking surgery after neoadjuvant chemotherapy (NACT-IDS). Primary endpoints were overall survival (OS) and progression-free survival (PFS). RESULTS: A total of 126 patients were included, 86.1% were stage III/IV, and 74.6% underwent lymph node dissection (LND). According to the Completeness of Cancer Resection (CCR) score, 83.7% had complete resection. Median OS was 130 months, and median PFS was 41 months. Pelvic and paraaortic LND had no significant impact on OS (p = 0.78) or DFS (p = 0.93), and this was confirmed in subgroups (advanced stages FIGO III/IV, CCR score 0/1 or 2/3, and timing of surgery PDS or NACT-IDS). Histological positive paraaortic lymph nodes had a significant negative impact on PFS in the whole population (HR 2.21, 1.18-4.39, p = 0.02) and in the CC0/CC1 population (HR, 2.28, 1.13-4.59, p = 0.02). CONCLUSIONS: Systematic pelvic and paraaortic LND in patients with LGSOC improved neither overall nor PFS. A prospective trial would be necessary to validate these results but would be difficult to conduct due to the rarity of this disease.

The OncoSim model: development and use for better decision-making in Canadian cancer control.

The Canadian Partnership Against Cancer was created in 2007 by the federal government to accelerate cancer control across Canada. Its OncoSim microsimulation model platform, which consists of a suite of specific cancer models, was conceived as a tool to augment conventional resources for population-level policy- and decision-making. The Canadian Partnership Against Cancer manages the OncoSim program, with funding from Health Canada and model development by Statistics Canada. Microsimulation modelling allows for the detailed capture of population heterogeneity and health and demographic history over time. Extensive data from multiple Canadian sources were used as inputs or to validate the model. OncoSim has been validated through expert consultation; assessments of face validity, internal validity, and external validity; and model fit against observed data. The platform comprises three in-depth cancer models (lung, colorectal, cervical), with another in-depth model (breast) and a generalized model (25 cancers) being in development. Unique among models of its class, OncoSim is available online for public sector use free of charge. Users can customize input values and output display, and extensive user support is provided. OncoSim has been used to support decision-making at the national and jurisdictional levels. Although simulation studies are generally not included in hierarchies of evidence, they are integral to informing cancer control policy when clinical studies are not feasible. OncoSim can evaluate complex intervention scenarios for multiple cancers. Canadian decision-makers thus have a powerful tool to assess the costs, benefits, cost-effectiveness, and budgetary effects of cancer control interventions when faced with difficult choices for improvements in population health and resource allocation.

Using the Cancer Risk Management Model to evaluate the health and economic impacts of cytology compared with human papillomavirus DNA testing for primary cervical cancer screening in Canada.

BACKGROUND: In Canada, discussion about changing from cytology to human papillomavirus (hpv) dna testing for primary screening in cervical cancer is ongoing. However, the Canadian Task Force on Preventive Health Care has not yet made a recommendation, concluding that the evidence is insufficient. METHODS: We used the cervical cancer and hpv transmission models of the Cancer Risk Management Model to study the health and economic outcomes of primary cytology compared with hpv dna testing in 14 screening scenarios with varying screening modalities and intervals. Projected cervical cancer cases, deaths, colposcopies, screens, costs, and incremental cost-effectiveness were evaluated. We performed sensitivity analyses for hpv dna test costs. RESULTS: Compared with triennial cytology from age 25, 5-yearly hpv dna screening alone from age 30 resulted in equivalent incident cases and deaths, but 55% (82,000) fewer colposcopies and 43% (1,195,000) fewer screens. At hpv dna screening intervals of 3 years, whether alone or in an age-based sequence with cytology, screening costs are greater, but at intervals of more than 5 years, they are lower. Scenarios on the cost-effectiveness frontier were hpv dna testing alone every 10, 7.5, 5, or 3 years, and triennial cytology starting at age 21 or 25 when combined with hpv dna testing every 3 years. CONCLUSIONS: Changing from cytology to hpv dna testing as the primary screening test for cervical cancer would be an acceptable strategy in Canada with respect to incidence, mortality, screening and diagnostic test volumes.

[Exploring a non-inflammatory clinical breast mass: Clinical practice guidelines]. / Exploration d'un syndrome de masse clinique non inflammatoire du sein: recommandations pour la pratique clinique.

PURPOSE: The aim of the study was to assess the diagnostic value of physical examination, radiologic explorations and percutaneous procedures of the breast in the exploration of a non-inflammatory palpable mass, in order to propose guidelines. METHOD: A systematic literature review was conducted in the Medline and Cochrane library databases. International guidelines in French and English language were also consulted until April 30th 2015. RESULTS: Physical examination of a non-inflammatory palpable breast mass is not sufficient to eliminate a breast cancer (LE2). Mammography alone has a sensitivity between 70 and 95% for the diagnosis of breast cancer (LE3). Echography alone has a sensitivity of 98 to 100% for the diagnosis of breast cancer (LE2). The core needle biopsy has a better sensitivity and specificity than the fine-needle aspiration for breast cancer diagnosis (LE2). The association of mammography and 2D echography presents excellent sensitivity and negative predictive value (close to 100 %) to exclude a breast cancer (LE3). A double evaluation using mammography and echography is recommended in the exploration of a non-inflammatory palpable breast mass (grade B).

[Benign breast tumors: Recommendations of Collège National des Gynécologues Obstétriciens Français (CNGOF)--Short text]. / Tumeurs bénignes du sein: recommandations pour la pratique clinique du Collège national des gynécologues et obstétriciens français (CNGOF)--Texte court.

Breast sonography is required with mammogram to explore clinical breast mass (grade B), colored unipore breast nipple discharge (grade C), or mastitis (grade C). Bi-RADS system is recommended to describe and classify breast-imaging abnormalities. For breast abscess, a percutaneous biopsy is recommended in case of mass or persistent symptoms (grade C). For mastodynia, when breast imaging is normal, no MRI neither breast biopsy is recommended (grade C). Percutaneous biopsy is recommended for BI-RADS 4-5 mass (grade B). For persistent erythematous breast nipple or atypical eczema lesion, a nipple biopsy is recommended (grade C). For distortion and asymmetry, a vacuum core needle biopsy is recommended because of the risk of underestimation by simple core needle biopsy (grade C). For BI-RADS 4-5 microcalcifications without ultrasound signal, a vacuum core needle biopsy of at least 11 gauges is recommended (grade B); in the absence of microcalcifications on radiograph carrots, additional samples are recommended (grade B). For atypical ductal hyperplasia, atypical lobular hyperplasia, lobular carcinoma in situ, flat epithelial with atypia, radial scar, mucocele with atypia, surgical excision is commonly recommended (grade C). Expectant management is feasible after multidisciplinary concertation. For these lesions, when excision is not in sano, no new excision is recommended except for pleomorphic or with necrosis CLIS (grade C). For grade 1 phyllode tumour, in sano surgical resection is recommended; for grade 2 phyllode, 10-mm margins are recommended (grade C). For breast papillary without atypia, complete disappearance of the radiologic signal is recommended (grade C). For breast papillary with atypia, complete surgical excision is recommended (grade C).

Using the Cancer Risk Management Model to evaluate colorectal cancer screening options for Canada.

BACKGROUND: Several screening methods for colorectal cancer (crc) are available, and some have been shown by randomized trials to be effective. In the present study, we used a well-developed population health simulation model to compare the risks and benefits of a variety of screening scenarios. Tests considered were the fecal occult blood test (fobt), the fecal immunochemical test (fit), flexible sigmoidoscopy, and colonoscopy. Outcomes considered included years of life gained, crc cases and deaths prevented, and direct health system costs. METHODS: A natural history model of crc was implemented and calibrated to specified targets within the framework of the Cancer Risk Management Model (crmm) from the Canadian Partnership Against Cancer. The crmm-crc permits users to enter their own parameter values or to use program-specified base values. For each of 23 screening scenarios, we used the crmm-crc to run 10 million replicate simulations. RESULTS: Using base parameter values and some user-specified values in the crmm-crc, and comparing our screening scenarios with no screening, all screening scenarios were found to reduce the incidence of and mortality from crc. The fobt was the least effective test; it was not associated with lower net cost. Colonoscopy screening was the most effective test; it had net costs comparable to those for several other strategies considered, but required more than 3 times the colonoscopy resources needed by other approaches. After colonoscopy, strategies based on the fit were predicted to be the most effective. In sensitivity analyses performed for the fobt and fit screening strategies, fobt parameter values associated with high-sensitivity formulations were associated with a substantial increase in test effectiveness. The fit was more cost-effective at the 50 ng/mL threshold than at the 100 ng/mL threshold. CONCLUSIONS: The crmm-crc provides a sophisticated and flexible environment in which to evaluate crc control options. All screening scenarios considered in this study effectively reduced crc mortality, although sensitivity analyses demonstrated some uncertainty in the magnitude of the improvements. Where possible, local data should be used to reduce uncertainty in the parameters.

[PROSPERE randomized controlled trial: laparoscopic sacropexy versus vaginal mesh for cystocele POP repair]. / Étude randomisée comparant la promontofixation cœlioscopique à la chirurgie prothétique par voie vaginale pour le traitement des cystocèles : PROSPERE (PROSthetic PElvic organ prolapse REpair).

BACKGROUND: Cystocele is a frequent and invalidating type of genital prolapse in woman. Sacropexy using synthetic mesh is considered the surgical gold standard, and the laparoscopic approach has supplanted the open abdominal route because it offers the same anatomical results with a lower morbidity. The use of mesh through the vaginal route may have many advantages: easiness to perform, shorter operative time and recovery, but may increase morbidity. In France, both laparoscopic sacropexy and vaginal mesh are commonly used to treat cystoceles. The French Haute Autorité de santé (HAS) has highlighted the lack of evaluation of safety assessment for vaginal meshes. METHOD/DESIGN: The main objective of the study is to compare the morbidity of laparoscopic sacropexy with vaginal mesh for cystocele repair. The primary endpoint will be the rate of surgical complications greater or equal to grade 2 of the Clavien-Dindo classification at 1-year follow-up. The secondary aims are to compare the functional results in the medium term (sexuality, urinary and bowel symptoms, pain), the impact on quality of life as well as anatomical results. PROSPERE is a randomized controlled trial conducted in 12 participating French hospitals. 262 patients, aged 45 to 75years old, with cystocele greater or equal to stage 2 of the POP-Q classification (isolated or not) will be included. Exclusion criterias are a previous surgical POP repair, and inability or contra-indication to one or the other technique. We have designed this study to answer the question of the choice between laparoscopic sacropexy and vaginal mesh for the treatment of cystocele. The PROSPERE trial aims to help better determine the indications for one or the other of these techniques, which are currently based on subjective choices or school attitudes. This is the reason why competent authorities have asked for such studies.

Evaluation of early regenerative processes in a preclinical pig model of acute kidney injury.

Renal failure due to ischemic injury is a common denominator of various clinical situations in critically ill patients. This study was designed to characterize the TPSO/Cholesterol synthesis and cell division pathways in response to different levels of ischemia. Porcine kidneys were subjected to either 60 min-warm ischemia (WI) or auto-transplanted after cold storage for 24 h at 4°C (CS), or both conditions (WI+CS), pathway activation and function were evaluated at 3 h, 3 and 7 days after reperfusion. CS combined to WI affects renal functions indicating a high degree of injury. During the first week of reperfusion, renal levels of free and esterified cholesterol, major cellular components, increased in CS group with an attenuated production when WI was associated. CS and WI+CS groups exhibited an elevated expression of cell cycle induction markers such as PCNA and stathmin. TSPO expression was highest in groups with the lowest injury, and correlated with kidney outcome, revealing its potential for diagnosis.

[Urinary incontinence and genital prolapse]. / Incontinence urinaire et prolapsus génital.

Prolapse commonly coexists with lower urinary tract dysfunction. If symptomatic stress urinary incontinence is often described by patients with low stage pelvic organ prolapse, obstructive symptoms are common in patients with stage 3 or 4 prolapse. Positive preoperative reduction testing in stress continent women planning prolapse repair is associated with a higher risk for postoperative leakage and clearly identify a high risk population. To date it has not been proven that urodynamic testing may provide more precise data than physical examination to advocate an additional stress urinary surgery at the time of prolapse repair. A systematic prophylactic Burch colposuspension significantly reduces the risk of postoperative SUI. In patients with occult SUI, a concomitant TVT at the time of vaginal prolapse surgery significantly reduces the risk of postoperative SUI. In patients without leakage during reduction testing, there is no evidence for performing a concurrent TVT.

[Virilizing ovarian tumors in the menopausal patient]. / Tumeurs virilisantes de l'ovaire chez la femme ménopausée.

Virilizing ovarian tumors are rare and can occur at any age. In postmenopausal women, they commonly present with signs of masculinization. These tumors should be suspected in any patient with virilization and high testosterone levels (>1ng/mL). Tumor localization is sometimes difficult. These tumors are usually benign; surgical resection is the accepted treatment. Masculinizing consequences of hormonal secretions may be managed by cosmetologic treatments which should not be overlooked.

Clinical indicators of progression in psoriatic arthritis: multivariate relative risk model.

OBJECTIVE: To identify markers for severe disease in psoriatic arthritis (PsA). METHODS: Patients with PsA followed prospectively according to a standard protocol over 14 years were included. Clinical and laboratory assessments of both active inflammation and clinical damage were performed at 6-month intervals according to a standard protocol. The information was entered into a computer database. Progression in damage was defined as transitions between damage states based on the number of damaged joints. Both univariate and multivariate models were developed to identify predictors for progression of damage. RESULTS: The best model available, based on patient characteristics at the time of being first seen in the psoriatic arthritis clinic suggests that a high number of effusions and of past medications predicts progression in damage, whereas a low sedimentation rate "protects" from such progression. CONCLUSIONS: Evidence of significant inflammation at first visit predicts progression of damage in the future, suggesting that patients with PsA should be offered more aggressive treatment early in the course of their disease.
