French college of gynecologists and obstetricians (CNGOF) recommendations for clinical practice: Place of breast self-examination in screening strategies.

Breast cancer is the most common female cancer in the world. Numerous studies have shown that the risk of metastatic disease increases with tumor volume. In this context, it is useful to assess whether the regular practice of formal breast self-examination (BSE) as opposed to breast awareness has an impact on the number of cancers diagnosed, their stage, the treatments used and mortality. DESIGN: The Commission of Senology (CS) of the Collège National de Gynécologie et Obstétrique Français (CNGOF) respected and followed the Grading of Recommendations Assessment, Development and Evaluation method to assess the quality of the evidence on which the recommendations were based. METHODS: The CS studied 16 questions individualizing four groups of women (general population, women aged over 75, high-risk women, and women previously treated for breast cancer). For each situation, it was determined whether the practice of BSE versus abstention from this examination led to detection of more breast cancers and/or recurrences and/or reduced treatment and/or increased survival. RESULTS: BSE should not be recommended for women in the general population, who otherwise benefit from clinical breast examination by practitioners from the age of 25, and from organized screening from 50 to 74 (strong recommendation). In the absence of data on the benefits of BSE in patients aged over 75, for those at high risk and those previously treated for breast cancer, the CS was unable to issue recommendations. Thus, if women in these categories wish to undergo BSE, information on the benefits and risks observed in the general population must be given, notably that BSE is associated with a higher number of referrals, biopsies, and a reduced quality of life.

OBJECTIVES: Breast cancer is the most common female cancer in the world. In France, over 60,000 new cases are currently diagnosed, and 12,000 deaths are attributed to it annually. Numerous studies have shown that the risk of metastatic disease increases with tumor volume. In this context, it is useful to assess whether the regular practice of breast self-examination (BSE) has an impact on the number of cancers diagnosed, their stage, the treatments used and mortality. DESIGN: the CNGOF's Commission de Sénologie (CS), composed by 17 experts and 3 invited members, drew up these recommendations. No funding was provided for the development of these recommendations. The CS respected and followed the GRADE (Grading of Recommendations Assessment, Development and Evaluation) method to assess the quality of the evidence on which the recommendations were based. METHODS: The CS studied 16 questions concerning BSE, individualizing four groups of women (general population, women aged over 75, high-risk women, and women previously treated for breast cancer). For each situation, it was determined whether the practice of BSE compared with abstention from this examination led to the detection of more breast cancers and/or recurrences and/or reduced treatment and/or increased survival. RESULTS: BSE should not be recommended for women in the general population, who otherwise benefit from a clinical breast examination (by the attending physician or gynecologist) from the age of 25, and from organized screening from 50 to 74 (strong recommendation). However, in the absence of data on the role of BSE in patients aged over 75, those at high risk of breast cancer and those previously treated for breast cancer, the CS was unable to issue recommendations. Thus, if women in these latter categories wish to undergo BSE, they must be given rigorous training in the technique, and information on the benefits and risks observed in the general population. Finally, the CS invites all women who detect a change or abnormality in their breasts to consult a healthcare professional without delay. CONCLUSION: BSE is not recommended for women in the general population. No recommendation can be established for women aged over 75, those at high risk of breast cancer and those previously treated for breast cancer.

How to optimize breast MRI protocol? The value of combined analysis of ultrafast and diffusion-weighted MRI sequences.

PURPOSE: The purpose of this retrospective study was to demonstrate the validity of early enhancement criteria on ultrafast magnetic resonance imaging (MRI) sequence to predict malignancy in a large population, and the benefit of diffusion-weighted imaging (DWI) to improve the performance of breast MRI. MATERIAL AND METHODS: Women who underwent breast MRI examination between April 2018 and September 2020 and further breast biopsy were retrospectively included. Two readers quoted the different conventional features and classified the lesion according to the BI-RADS classification based on the conventional protocol. Then, the readers checked for the presence of early enhancement (≤ 30 s) on ultrafast sequence and the presence of an apparent diffusion coefficient (ADC) ≥ 1.5 × 10-3 mm2/s to classify the lesions based on morphology and these two functional criteria only. RESULTS: Two hundred fifty-seven women (median age: 51 years; range: 16-92 years) with 436 lesions (157 benign, 11 borderline and 268 malignant) were included. A MRI protocol plus two simple functional features, early enhancement (≤ 30 s) and an ADC value ≥ 1.5 × 10-3 mm2/s, had a greater accuracy than the conventional protocol to distinguish benign from malignant breast lesions with or without ADC value (P = 0.01 and P = 0.001, respectively) on MRI, mainly due to better classification of benign lesions (increased specificity) with increasing diagnostic confidence of 3.7% and 7.8% respectively. CONCLUSION: BI-RADS analysis based on a simple short MRI protocol plus early enhancement on ultrafast sequence and ADC value has a greaterr diagnostic accuracy than a conventional protocol and may avoid unnecessary biopsy.

O-RADS MRI Classification of Indeterminate Adnexal Lesions: Time-Intensity Curve Analysis Is Better Than Visual Assessment.

Background The MRI Ovarian-Adnexal Reporting and Data System (O-RADS) enables risk stratification of sonographically indeterminate adnexal lesions, partly based on time-intensity curve (TIC) analysis, which may not be universally available. Purpose To compare the diagnostic accuracy of visual assessment with that of TIC assessment of dynamic contrast-enhanced MRI scans to categorize adnexal lesions as benign or malignant and to evaluate the influence on the O-RADS MRI score. Materials and Methods The European Adnex MR Study Group, or EURAD, database, a prospective multicenter study of women undergoing MRI for indeterminate adnexal lesions between March 2013 and March 2018, was queried retrospectively. Women undergoing surgery for an adnexal lesion with solid tissue were included. Solid tissue enhancement relative to outer myometrium was assessed visually and with TIC. Contrast material washout was recorded. Lesions were categorized according to the O-RADS MRI score with visual and TIC assessment. Per-lesion diagnostic accuracy was calculated. Results A total of 320 lesions (207 malignant, 113 benign) in 244 women (mean age, 55.3 years ± 15.8 [standard deviation]) were analyzed. Sensitivity for malignancy was 96% (198 of 207) and 76% (157 of 207) for TIC and visual assessment, respectively. TIC was more accurate than visual assessment (86% [95% CI: 81, 90] vs 78% [95% CI: 73, 82]; P < .001) for benign lesions, predominantly because of higher specificity (95% [95% CI: 92, 98] vs 76% [95% CI: 68, 81]). A total of 21% (38 of 177) of invasive lesions were rated as low risk visually. Contrast material washout and high-risk enhancement (defined as earlier enhancement than in the myometrium) were highly specific for malignancy for both TIC (97% [95% CI: 91, 99] and 94% [95% CI: 90, 97], respectively) and visual assessment (97% [95% CI: 92, 99] and 93% [95% CI: 88, 97], respectively). O-RADS MRI score was more accurate with TIC than with visual assessment (area under the receiver operating characteristic curve, 0.87 [95% CI: 0.83, 0.90] vs 0.73 [95% CI: 0.68, 0.78]; P < .001). Conclusion Time-intensity curve analysis was more accurate than visual assessment for achieving optimal diagnostic accuracy with the Ovarian-Adnexal Reporting and Data System MRI score.

[Non-genetic indications for risk reducing mastectomies: Guidelines of the National College of French Gynecologists and Obstetricians (CNGOF)]. / Indications des mastectomies de réduction de risque en dehors du risque avéré de prédisposition héréditaire : recommandations du Collège national des gynécologues et obstétriciens français (CNGOF).

OBJECTIVE: To determine the value of performing a risk-reducting mastectomy (RRM) in the absence of a deleterious variant of a breast cancer susceptibility gene, in 4 clinical situations at risk of breast cancer. DESIGN: The CNGOF Commission of Senology, composed of 26 experts, developed these recommendations. A policy of declaration and monitoring of links of interest was applied throughout the process of making the recommendations. Similarly, the development of these recommendations did not benefit from any funding from a company marketing a health product. The Commission of Senology adhered to the AGREE II (Advancing guideline development, reporting and evaluation in healthcare) criteria and followed the Grading of Recommendations Assessment, Development and Evaluation (GRADE) method to assess the quality of the evidence on which the recommendations were based. The potential drawbacks of making recommendations in the presence of poor quality or insufficient evidence were highlighted. METHODS: The Commission of Senology considered 8 questions on 4 topics, focusing on histological, familial (no identified genetic abnormality), radiological (of unrecognized cancer), and radiation (history of Hodgkin's disease) risk. For each situation, it was determined whether performing RRM compared with surveillance would decrease the risk of developing breast cancer and/or increase survival. RESULTS: The Commission of Senology synthesis and application of the GRADE method resulted in 11 recommendations, 6 with a high level of evidence (GRADE 1±) and 5 with a low level of evidence (GRADE 2±). CONCLUSION: There was significant agreement among the Commission of Senology members on recommendations to improve practice for performing or not performing RRM in the clinical setting.

MRI of intestinal endometriosis.

Endometriosis is a common gynecological condition of unknown etiology, which mainly affects women of reproductive age. The commonest site of gastrointestinal endometriosis is the rectosigmoid colon. Involvement of the sigmoid, cecum, appendix, and small bowel are less common, but one third of rectosigmoid endometriosis is associated with right-sided extra-pelvic bowel endometriosis. Intestinal endometriosis represents one of the most severe forms of deep endometriosis (DE). Magnetic resonance imaging (MRI) is recommended as a second-line technique in the preoperative workup of DE, especially for gastrointestinal endometriosis. An optimal MRI protocol is required for a complete mapping of endometriotic lesions. MRI could be used as a triage test in the diagnosis of rectosigmoid colon endometriosis. Magnetic resonance enterography should be additionally performed requiring a specific additional MRI protocol for the evaluation of multicentric intestinal endometriotic lesions. Except other imaging techniques, the aim of this chapter is to expose indications for MRI, technical requirements, patient preparation, MRI protocols, and criteria for the diagnosis of intestinal endometriosis.

Magnetic resonance imaging classification of deep pelvic endometriosis: description and impact on surgical management.

STUDY QUESTION: Is an MRI classification of deep pelvic endometriosis (DE) able to correctly predict the risk of DE surgery. SUMMARY ANSWER: A new radiological classification, that we have called the deep pelvic endometriosis index (dPEI) classification, is accurate and reproducible to assess the extension of the disease in central and lateral compartments and well correlated with operating time, hospital stay duration and the risk of voiding dysfunction. WHAT IS KNOWN ALREADY: Few imaging classifications are currently available to predict the extent of DE to help preoperative assessment of surgical outcomes and provide the patient with objective information about the risk of surgical complications. STUDY DESIGN, SIZE, DURATION: Retrospective monocentric observational study was conducted between 01 January 2017 and 31 December 2018 and included 150 women (mean age = 34.5 years, 20-52 years) with DE on MRI and who subsequently underwent surgery. PARTICIPANTS/MATERIALS, SETTING, METHODS: Two radiologists independently graded the disease according to MRI-based Enzian classification (A (rectovaginal septum and vagina locations), B (uterosacral locations) and C (rectosigmoid locations)) and a new radiological classification, that we have called the dPEI, that grades the severity of DE as: mild, moderate or severe DE. MRI findings and classification were correlated with surgical and pathological results. MAIN RESULTS AND THE ROLE OF CHANCE: MRI-based and surgical Enzian classifications were concordant for A lesions in 78.7% (118/150), for B lesions in 34.7% (52/150) and for C lesions in 82.7% (124/150). Operating time and hospital stays were longer in Group A2 (rectovaginal septum and vagina, 1-3 cm) compared to A0, B2 (uterosacral, 1-3 cm) compared to B0, C3 (rectosigmoid >3 cm) compared to C2 (rectosigmoid 1-3 cm) or C0 (P < 0.001), in severe compared to moderate DE patients, and in moderate compared to mild extensive patients (P < 0.01). Patients with vaginal or rectosigmoid involvement were respectively six and three times more likely to experience high-grade complications according to Clavien-Dindo classification than patients without vaginal or rectosigmoid disease (P < 0.001). Postoperative voiding dysfunction was correlated with A lesions (odds ratio (OR) = 6.82, 95% CI 2.34-20.5), moderate or severe DE (OR = 4.15, 95% CI 1.26-17.9), the presence of at least unilateral lateral pelvic involvement (OR = 3.6, 95% CI 1.14-11.2, P = 0.03) and C lesions (OR = 2.6, 95% CI 1.03-6.8, P < 0.01). LIMITATIONS, REASONS FOR CAUTION: The study was conducted in an expert center and needs to be validated in a multicenter study. There is a limited number of patients with lateral pelvic endometriosis beyond the parietal fascia, probably due to the low prevalence of this disease presentation. WIDER IMPLICATIONS OF THE FINDINGS: MRI imaging can be used to accurately predict postoperative complications for women with DE. This may help the clinician to preoperatively inform a patient about the risks of surgery. Larger clinical studies are required to validate these results. STUDY FUNDING/COMPETING INTEREST(S): No external funding was used for this study.

Breast MRI: Is Faster Better?

OBJECTIVE. Fast breast MRI protocols have the same sensitivity as conventional protocols, but their specificity is variable and can be inadequate. An ultrafast sequence provides early enhancement of lesion characteristics that optimize the characterization of the fast protocol, increasing positive predictive values without increasing time. CONCLUSION. These new abbreviated protocols could constitute a viable screening tool both for women at high risk of breast cancer and for those at intermediate risk with high breast density.

Abbreviated breast MRI combining FAST protocol and high temporal resolution (HTR) dynamic contrast enhanced (DCE) sequence.

PURPOSE: We evaluated the diagnostic value of a high temporal resolution (HTR) dynamic contrast enhanced (DCE) sequence added to a FAST protocol. MATERIALS AND METHODS: 120 women (mean age = 55 years (28-88)) who underwent breast MRI between July 2016 and March 2017 and in whom a biopsy was performed (i.e., gold standard) (n = 179: 69 benign, 7 borderline and 103 malignant lesions) were retrospectively and consecutively included. Two readers classified lesions according to the Breast Imaging-Reporting and Data System (BI-RADS) by reading: a FAST protocol (T1W, T2W, T1W-fat saturated 2 min after injection) and then a FULL standard protocol. Independently they determined if lesions were visible and when (Time To Enhancement (TTE)) on the HTR-DCE sequence. An Abbreviated protocol was then built using data from the HTR-DCE sequence added to the FAST protocol. RESULTS: All lesions were visible with the FAST protocol. 171/179 (95.5%) lesions were detected by reading theHTR-DCE sequence. There were a higher number of cancers rated BI-RADS 3 (PPV of malignancy of 27.6% (8/29) in FAST versus 18.7% (3/16) FULL protocol). An early enhancement on the HTR-DCE sequence (TTE < 31 s) was associated with malignancy with an OR 5.6 (CI 95%: 3.3-20.4) (p < 0.0001). Adding a TTE < 31 s to FAST analysis (AUROC = 0.826) significantly improved lesion characterization with a diagnostic gain of 10.6% (19/179) lesions correctly reclassified (p = 0.0034) compared to FAST protocol; with shorter acquisition time (7 min 48 s versus 13 min 54 s). CONCLUSION: Adding an HTR-DCE sequence to a FAST protocol increases diagnostic performance reaching that of the FULL protocol while reducing acquisition time.

Comparison of 3-Tesla to 1.5-Tesla Magnetic Resonance Enterography to assess multifocal and multicentric bowel endometriosis: Results in routine practice.

STUDY OBJECTIVE: To compare 1.5-Tesla (1.5 T) to 3-Tesla (3 T) Magnetic resonance enterography (MRE) in assessing multifocal (multiple lesions affecting the same segment) and multicentric (multiple lesions affecting several digestive segments) bowel endometriosis in patients with suspected-colorectal endometriosis, in routine practice. STUDY DESIGN: We conducted a retrospective, comparative study in Tenon University Hospital, Paris, France. We included patients scheduled for colorectal resection from April 2014 to February 2018. All patients underwent 1.5 T or 3 T MRE before surgery and endometriosis lesions were confirmed by surgery. The diagnostic performance of 1.5 T and 3 T MRE was evaluated by sensitivity, specificity, positive and negative predictive values (PPV and NPV), accuracy, positive and negative likelihood ratios (LR) and area under the curve of receiver operating curves (AUC ROC). RESULTS: Ninety-eight patients were included. Fifty-two (53%) patients presented unifocal lesions, 31 (32%) multifocal lesions, and 23 (24%) multicentric lesions. In assessment of multifocal lesions, the sensitivity, specificity, positive and negative LRs were 0.57 (12/21), 0.89 (23/26), 4.95 and 0.58 for 1.5 T MRE, and 0.10 (1/10), 0.95 (39/41), 2.05 and 0.95 for 3 T MRE. For the diagnosis of multicentric lesions, 1.5 T MRE showed sensitivity, specificity, positive and negative LRs of 0.46 (5 of 11), 0.92 (33 of 36), 5.45 and 0.60 respectively and 3 T MRE showed sensitivity, specificity, and negative LRs of 0.33 (4/12), 1.00 (39/39), and 0.67, respectively. 1.5 T MRE was more accurate than 3 T MRE for diagnosing multifocal lesions (p = 0.02), but there was no difference for multicentric lesion assessment (p = 0.66). CONCLUSION: In routine conditions, 3 T MRE and 1.5 T MRE are of similar low performance for diagnosing multifocal and multicentric bowel endometriosis.

[Imaging in the initial and preoperative assessment of endometriosis]. / Apport de l'imagerie dans le bilan initial et préopératoire de l'endométriose.

The diagnosis of pelvic endometriosis is based on the combination of clinical examination, endovaginal ultrasonography and pelvic MRI. Ultrasonography displays a moderate sensitivity and a high specificity. Pelvien MRI displays a better sensitivity and lower specificity.
