[Breast density assessment and organised breast cancer screening]. / Catégorisation de la densité mammaire et dépistage organisé du cancer du sein.

INTRODUCTION: The objective of this study was to evaluate the intra- and inter-rater agreement of radiologists regarding the evaluation of breast density. METHODOLOGY: Breast density assessments of 120 cases were performed by four radiologists in the city of Ouagadougou according to the fifth edition of the American College of Radiology BI-RADS atlas. Cohen's weighted kappa coefficients and Fleiss kappa coefficients were used to estimate agreement between observers and with a panel of three experts radiologists. A new evaluation of the 120 cases was performed by all raters one month after the initial evaluation. RESULTS: Inter-rater kappa coefficients ranged from 0.55 to 0.74. The Fleiss kappa coefficient was 0.58, 0.43, 0.41, and 0.43 for categories A, B, C, and D respectively. In terms of classification into "sparse breasts" and "dense breasts", the kappa coefficients ranged from 0.47 to 0.67. Taking the results of the expert panel as a reference, the proportion of false positives in the diagnosis "dense breasts" ranged from 18.6% to 26.8%. Intraobserver agreement was good. CONCLUSION: Our study showed moderate to good intra- and inter-raters agreements. Upgrading and harmonisation of practices will be used to empower radiologists to participate in organised breast cancer screening in Burkina Faso.

Factors associated with mammography screening among Reunionese women : a cross-sectional study.

OBJECTIVE: To explore the factors associated with the uptake of mammography screening in Reunionese women aged 50-65 years. METHODS: This study included all women aged 50 to 65 years participating in a population-based cross-sectional study "FOSFORE". Participants were recruited between March and June 2017 using two sampling frames. The first frame consisted of households with a landline telephone, with or without a mobile line, by first randomly generating a telephone number and then randomly selecting an individual from among all eligible women in the household. The second sampling frame was constituted of women with an exclusive mobile line, who were selected directly if they met the eligibility criteria. Data were weighted for age and socio-professional status to ensure representativeness at the Reunion Island level. Weighted logistic regression was used to calculate odds ratios while adjusting for confounders. RESULTS: 417 women were included in the study; 63.8% were up to date with guidelines on mammography screening and 36.2% were not up to date. Four factors were significantly associated with mammography screening, with an adjusted odds ratio of 2.92 (95% CI 1.51-5.61) for not having an Active Solidarity Income, 1.98 (95% CI 1.22-3.23) for having a regular gynecological follow-up by a physician, 6.53 (95% CI 3.23-13.21) for performing a Pap smear test in the past two years, and 2.07 (95% CI 1.21-3.52) for having an adequate literacy level (HLQ3). CONCLUSION: The findings of this study suggest that higher socio-economic status is an indicator of participation in mammography screening in La Réunion, and future educational and intervention programs should target women in deprived areas.

[Second reading in breast cancer screening program: State of knowledge and future]. / Seconde lecture en dépistage organisé du cancer du sein. États des lieux et perspectives d'évolution.

Second reading is an important part of breast cancer organized screening program. Image quality control and detection of non-diagnosed cancer by first reader are the two goals of this process. In France, 6 % of all screening cancer are diagnosed by second reading, actually done on screen film. With the technologic evolution (Digital breast tomosynthesis, Artificial intelligence) and societal digitalization, this process need to evolve. After some report about organization and results for second reading in France and outside, current and future shortcomings, proposition from professionals involved in breast cancer screening are made to improve this public health program.

[The HRT follow-up consultation. What to do in case of breast tumour (clinical or radiological) and microcalcifications. Postmenopausal women management: CNGOF and GEMVi clinical practice guidelines]. / La consultation de suivi du THM. Conduite à tenir en cas de tumeur mammaire (clinique ou radiologique) et de microcalcifications. RPC Les femmes ménopausées du CNGOF et du GEMVi.

OBJECTIVE: The objective was to evaluate the diagnostic value of clinical examination and complementary imaging in the exploration of a breast lump or microcalcifications occurring in a postmenopausal woman taking hormonal replacement therapy (HRT), based on a systematic review of the literature in order to make recommendations for HRT management. METHODS: A literature review was conducted using Medline, Cochrane Library data and international recommendations in French and English until 2020. RESULTS: In the presence of a clinical breast mass in postmenopausal women, there is no clinical evidence to rule out cancer. A double evaluation by mammography and ultrasound is recommended and allows the imaging to be classified into 5 BI-RADS categories. The diagnostic management of masses classified BI-RADS 4 and 5 should be based on percutaneous sampling, with microbiopsy being the first step. A total of four situations may arise: 1. Clinical examination has detected a breast mass, but there is no imaging abnormality. In this case, the imaging NPV is high (>96%). If the clinical lesion increases in size, a tissue biopsy should be performed, while continued routine breast screening is recommended if the lesion remains stable and HRT can be continued. 2. Clinical examination, mammography, and ultrasound are in favour of a cyst. Simple cysts can be punctured if painful. There is no contraindication to continuing HRT in the case of simple cysts. Management options for complicated and complex cysts are no different from those offered to women without HRT. Continuation of HRT must consider their histological nature. 3. Clinical examination, mammography, and ultrasonography suggest a benign solid tumour. The management of these benign breast lesions (fibroadenoma…) is not different in women taking an HRT and there is no contraindication to continue the HRT. 4: Clinical examination, imaging and microbiopsy diagnose a malignant tumour. It is imperative that the HRT be stopped, whatever the hormonal dependence of the tumour and whether it is invasive or in situ. The management of the cancerous tumour must consider the updated breast cancer treatment guidelines. In the presence of microcalcifications, the course of action to be taken depends on the BI-RADS classification, established according to the morphology and arrangement of the calcifications. In case of suspicious microcalcifications (BI-RADS 4 or 5), a guided macrobiopsy should be performed. Diagnostic and therapeutic management in these patients is no different from that offered to women without HRT. Discontinuation of HRT is necessary in cases of malignancy (in situ or invasive cancer). CONCLUSION: A rigorous multidisciplinary approach is necessary for the exploration of a breast mass or microcalcifications in a postmenopausal woman.

Accuracy of mammography, sonography and magnetic resonance imaging for detecting silicone breast implant ruptures: A retrospective observational study of 367 cases.

INTRODUCTION: The purpose of this study was to assess the efficacy of magnetic resonance imaging, ultrasound and mammography in detecting breast implant rupture. METHODS: This retrospective study included all cases of breast implant revision. Implant integrity was determined preoperatively by magnetic resonance imaging, ultrasound and mammography. The primary study endpoint was the surgical finding. The sensitivity, specificity, positive and negative predictive value and positive and negative likelihood ratio of the tests were evaluated. RESULTS: Two hundred and thirty-four (234) patients were included; 213 mammographies, 295 ultrasounds and 160 magnetic resonance imagings were carried out. While 114 clinical ruptures were confirmed, 253 implants remained intact. Magnetic resonance imaging was the most sensitive (99%); outperforming mammography (sensitivity: 70%). Mammography was the most accurate in diagnosis of intact implant (specificity: 93%), and magnetic resonance imaging was second (specificity: 78%). Ultrasound was rated intermediately. Positive mammography signifies a rupture in 84% of cases, whereas magnetic resonance imaging (positive predictive value: 78%) can be mistaken in 20% of cases. Negative ultrasound and magnetic resonance imaging rule out a rupture (negative predictive value of 93% and 99% respectively). Mammography and ultrasound are more accurate than magnetic resonance imaging in diagnosing implant rupture (positive likelihood ratios of 9.78, 8.24 and 4.44 respectively). Magnetic resonance imaging provides convincing affirmation of implant integrity (negative likelihood ratio: 0.02). CONCLUSION: Ultrasound seems to be the most reliable imaging method for patients younger than 50 years. In cases where doubt exists, mammography ensures supplementary assessment. In patients over 50 years of age, mammography and ultrasound should be carried out immediately. If necessary, magnetic resonance imaging rules out a hypothesized rupture.

[Preoperative breast imaging review: Interests and limits of specialized validation in oncology]. / Relecture préopératoire en sénologie : intérêts et limites d'une validation spécialisée en oncologie.

OBJECTIVES: To evaluate the impact of systematic radiological review by breast specialist radiologist of malignant breast lesion imaging on the therapeutic management of patients. MATERIALS AND METHODS: Data collection was performed for patients with histopathologically proved breast cancer or suspicious breast lesion on imaging realized out of our institution. Patients underwent systematic mammary and axillary ultrasound, imaging review and if necessary complementary mammographic images. We analyzed the number of additional breast biopsies and axillary lymph node fine needle aspiration (FNA) with their histopathological results. We assessed their impact by comparing the final surgical treatment to the one planned before review. RESULTS: Two hundred and seventeen patients were included, with a total of 230 BIRADS 0, 4, 5 or 6 breast lesions. Seventy-six additional breast core biopsies were realized, leading to diagnose 43 additional BIRADS 6 lesions (24 infiltrative carcinomas, 9 DCIS and 10 atypical lesions) in 30 patients (13.82%). Thirty-five additional lymph node FNA were realized with 12 metastatic nodes and 3 false negative samples. Imaging review lead to change surgical treatment in 59 patients (27.19%, P<0.01) with modification in breast surgery in 37 patients, axillary surgery in 8 patients and both sites surgery in 12 patients. CONCLUSION: This study shows an impact of systematic radiological review by breast specialist radiologist in therapeutic management of patients treated for malignant breast lesion.

[Artificial intelligence in healthcare: major potential for innovations in our health system]. / L'intelligence artificielle en santé, un potentiel majeur d'innovations pour notre système de santé.

Artificial intelligence (AI) is rapidly being extended across health systems with multiple cases of its use already reported. The most operational technique is machine learning with image recognition in imaging. Solutions derived from this approach, as well as other applications of AI, are presented in two major fields: cancer management and geriatric care.

[Ultrasound for Breast Cancer Screening: an Effective Tool in a Personalized Screening]. / L'échographie dans le dépistage du cancer du sein: un outil efficace dans un dépistage personnalisé.

Screening mammography is the only imaging modality with proved decrease in breast cancer mortality. Ultrasound has been proposed as additional tool for screening. Controversies remain about the real value of sonography in this setting. In Caucasian women with dense breast, sonography improves significantly breast cancer detection, but also increases the false positive cases, biopsies and costs. A careful selection of women who may benefit from additional screening with sonography is mandatory.

[Clinical practice guidelines: Benign breast tumor--Aims, methods and organization]. / Recommandations pour la pratique clinique: tumeurs bénignes du sein--Objectifs, méthodes et organisation.

Conversely to breast cancer, few data and guidelines are available to explore and manage benign breast disorders. Therefore, the Collège national des gynécologues et obstétriciens français (CNGOF - French College of Gynaecologists and Obstetricians) decided to establish clinical practice guidelines for benign breast tumour (BBT). CNGOF appointed a committee with responsibility for selecting experts, compiling questions and summarizing the recommendations. The summary of valid scientific data for each question analyzed by the experts included a level of evidence, based on the quality of the data available and defined accordingly rating scheme developed by the Haute Autorité de santé (French National Authority for Health).

[Explorations of breast microcalcifications: Guidelines]. / Exploration des microcalcifications mammaires: recommandations.

OBJECTIVES: To assess imaging performances for the detection, characterization and biopsy of breast microcalcifications and make recommendations. MATERIALS AND METHODS: French and English publications were searched using PubMed, Cochrane Library and international learned societies recommendations. RESULTS: Digital mammography (DR [Direct Radiography] and CR [Computed Radiography]) and screen-film mammography demonstrate good performances for the detection and the characterization of breast microcalcifications. Systematic use of the 2013 edition of the BI-RADS lexicon is recommended for description and characterization of microcalcifications. Faced with BI-RADS 4 or 5 microcalcifications, breast ultrasound is recommended but a normal result does not eliminate the diagnosis of cancer and other examination should be performed. Literature review does not allow recommending digital breast tomosynthesis, elastography or MRI to analyze microcalcifications. In case of probably benign microcalcifications (BI-RADS 3), six months, one year and at least two years follow-up are recommended. In case a biopsy is indicated, it is recommended to use a vacuum-assisted macrobiopsy system with 11-gauges needles or bigger. If no calcification is visible on the radiography of the specimen, it is recommended to obtain additional samples.

[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).

[Breast pain: Recommendations]. / Syndrome douloureux mammaire: recommandations.

OBJECTIVES: To evaluate the diagnostic value of clinical examination and additional tests in the exploration of breast pain, to evaluate the strategy of their care and to provide recommendations. METHODS: A literature search in English and French carried out by consulting the databases PubMed, Cochrane Library and international recommendations. RESULTS: Clinical examination and interrogation, with the use of visual analog scale used to differentiate non-cyclical breast pain from mastodynia (LE2). A calendar can be used to characterize the cyclical breast pain (LE3). Using a questionnaire can help to characterize the pain (LE3). In the absence of palpable abnormality, it is not recommended to modify systematic or individual screening modalities (LE2). MRI is not recommended in case of normal mammography and sonography. Explorations biopsy is guided by imaging. The therapeutic management includes reassurance after a normal clinical evaluation and/or normal radiological findings (LE2), and precise fitting of a brassière. In case of failure of this first approach, NSAIDs gel can be proposed (LE1-2).

[Breast cancer screening in thirteen French departments]. / Dépistage du cancer du sein dans treize départements français.

BACKGROUND: In France, breast cancer screening programme, free of charge for women aged 50-74 years old, coexists with an opportunistic screening and leads to reduction in attendance in the programme. Here, we reported participation in organized and/or opportunistic screening in thirteen French departments. POPULATION AND METHODS: We analyzed screening data (organized and/or opportunistic) of 622,382 women aged 51-74 years old invited to perform an organized mammography screening session from 2010 to 2011 in the thirteen French departments. The type of mammography screening performed has been reported according to women age, their health insurance scheme, the rurality and the socioeconomic level of their area or residence. We also represented the tertiles of deprivation and participation in mammography screening for each department. RESULTS: A total of 390,831 (62.8%) women performed a mammography screening (organized and/or opportunistic) after the invitation. These women were mainly aged from 55-69 years old, insured by the general insurance scheme and lived in urban, semi-urban or affluent areas. CONCLUSION: The participation in mammography screening (organized and opportunistic) in France remains below the target rate of 70% expected by health authorities to reduce breast cancer mortality through screening.

[Role of imaging procedures in the diagnosis of synchronous bilateral breast cancer]. / Place de l'imagerie dans le diagnotic des cancers du sein bilatéraux synchrones.

OBJECTIVE: To investigate the role of imaging procedures in the diagnosis of synchronous bilateral breast cancer (SBBC) PATIENTS AND METHODS: The patient group consisted of consecutive women undergoing managed for SBBC in our institution between January 2006 and July 2012. We defined SBBC as bilateral breast tumors diagnosed simultaneously or up to 3 months after initial diagnosis. Clinical data included comorbidities, BMI (kg/m(2)), preoperative breast imaging modalities used and their findings. RESULTS: Of the 2322 patients with newly diagnosed breast cancer treated on the study period, 46 patients with the diagnosis of SBBC were enrolled to the study. A total of 41.3% patients had family history of breast cancer. A total of 56.52% had clinical symptoms. The most frequent situation of diagnosis (32.6%) was the association of a palpable tumor and a contralateral radiologic abnormality. MRI permitted the diagnosis of 19.6% occult contralateral lesions. DISCUSSION AND CONCLUSION: Clinical examination and conventional imaging procedures (mammography and sonography) detects the majority (76%) of synchronous contralateral breast cancers. A family history of breast cancer, a multifocal breast tumor or the presence of an invasive lobular carcinoma should be arguments for the realization of a breat MRI to eliminate contralateral malignancy.
