[Surgery or not on an atypical breast lesion? Taking anxiety into account in shared decision support from a prospective cohort of 300 patients]. / Opérer ou non une lésion atypique du sein ? Prise en compte de l'anxiété dans l'aide à la décision partagée à partir d'une cohorte prospective de 300 patientes.

INTRODUCTION: Organized and individual breast screening have been accompanied by an increase in the detection of "atypical breast lesions (ABL)". Recently, the NOMAT multicenter study proposed a predictive model of the risk of developing breast cancer after detection of an ABL in order to avoid surgical removal of "low-risk" lesions. It also aimed to provide information on psychological experience, in particularly anxiety, to assist in the shared medical decision process. METHODS: Three hundred women undergoing surgery for ABL were included between 2015 and 2018 at 18 French centers. Women completed questionnaires before and after surgery assessing their level of anxiety (STAI-State, STAI-Trait), their level of tolerance to uncertainty, their perceived risk of developing a breast cancer, and their satisfaction with the management care. RESULTS: One hundred nighty nine patients completed the STAI-Status before and after surgery. Overall, a decrease in anxiety level (35.4 vs 42.7, P<0.001) was observed. Anxious temperament and greater intolerance to uncertainty were significantly associated swith decreased anxiety (33%), whereas younger age was associated with increased anxiety (8%). CONCLUSION: Surgery for ABL seems to be associated with only a few cases with an increase in anxiety and seems to increase the perception of the risk of developing breast cancer. Taking into account the psychological dimension remains in all cases essential in the process of shared therapeutic decision.

The role of tomosynthesis in breast cancer staging in 75 patients.

OBJECTIVES: Compare tomosynthesis to mammography, ultrasound, MRI, and histology for the detection and staging of BI-RADS 4-5 anomalies, as a function of breast composition, lesion location, size, and histology. PATIENTS AND METHODS: Seventy-five patients underwent mammography, tomosynthesis, ultrasound, and MRI. The diagnostic accuracy of the different examinations was compared. RESULTS: The sensitivities for detection were as follows: 92.5% with MRI, 79% for ultrasound, 75% for tomosynthesis, and 59.5% for mammography. Tomosynthesis improves the sensitivity of mammography (P=0.00013), but not the specificity. The detection of multifocality and multicentricity was improved, but not significantly. Tomosynthesis identified more lesions than mammography in 10% of cases and improved lesion staging irrespective of the density, but was still inferior to MRI. The detection of ductal neoplasia was superior with tomosynthesis than with mammography (P=0.016), but this was not the case with lobular cancer. The visualization of masses was improved with tomosynthesis (P=0.00012), but not microcalcifications. Tomosynthesis was capable of differentiating lesions of all sizes, but the smaller lesions were easier to see. Lesion sizes measured with tomosynthesis, excluding the spicules, concurred with histological dimensions. Spicules lead to an overestimation of the size. CONCLUSION: In our series, tomosynthesis found more lesions than mammography in 10% of patients, resulting in an adaption of the surgical plan.

Shear wave elastography contribution in ultrasound diagnosis management of breast lesions.

PURPOSE: To determine the diagnosis performance of shear wave elastography in the differentiation of benign and malignant breast lesions and the factors influencing the elasticity values. To suggest an appropriate management of breast lesions using the ultrasound-elastography combination. PATIENTS AND METHODS: Monocentric retrospective study of 167 breast lesions classified by conventional ultrasound as BI-RADS category 3 or higher that underwent an elastography study and histological analysis. RESULTS: The analysis of qualitative parameters, according to the classification established in this study, allows us to obtain a sensitivity of 91.1% and a specificity of 92.3%. These values are very close to or better than the quantitative parameters Emax and Emean. Different Emax thresholds values were established based on the long axis of the lesion and its palpable character, which appeared to be significant factors influencing elasticity. The management of breast lesions by combining ultrasound and elastography, as proposed here, allows us to keep the sensitivity of an ultrasound (96%), while doubling its specificity (86.2% versus 43.1%). CONCLUSION: With the complementary nature of their performance, the combination of conventional ultrasound and shear wave elastography can improve the management of breast lesions. The qualitative classification proposed appears to be relevant assistance in lesion characterization.

[Evaluation of stereotactic core biopsies of the breast with the 10-gauge Vacora® biopsy device: a review of 541 procedures]. / Évaluation des macrobiopsies mammaires stéréotaxiques par système Vacora® 10-gauge (541 procédures).

PURPOSE: To evaluate stereotactic core biopsies of the breast with the 10-gauge Vacora(®) biopsy device. PATIENTS AND METHODS: Retrospective study of 541 procedures in 502 patients performed between 2007 and 2009. RESULTS: The procedure failed in 2% of cases, non-complicated hematomas occurred in 5% of cases and unsightly scars in two cases. A clip was deployed in 70% of cases, successfully in 99% of cases. The procedure was well tolerated in 88% of cases. Core biopsies confirmed a benign lesion in 55% of cases, borderline lesions in 19% of cases and malignant lesions in 26% of cases with complementary surgery performed in 40% of cases. For surgical lesions, sensitivity, specificity, PPV and NPV were 89%, 100%, 100% and 84% respectively. Atypical ductal dysplasia was under-estimated in 8% of cases while DCIS was under-estimated in 14% of cases. After review of the mammograms, 3% of Bi-Rads 4 lesions were reclassified as Bi-Rads 3 lesions, all benign at core biopsy. Half of these results were from screening mammography programs. CONCLUSION: Results with the 10-gauge Vacora(®) biopsy device are similar to reports from the literature, mainly using the Mammotome system, with regards to tolerability and reliability for a lesser cost.

[Bronchogenic cyst disclosed by pericarditis. Value of transesophageal echocardiography apropos of a case]. / Kyste bronchogénique révélé par une péricardite. Intérêt de l'échocardiographie transoesophagienne à propos d'un cas.

Pericarditis is one of the possible complications of mediastinal teratoma. Bronchogenic cysts are the commonest mediastinal cysts and may be observed at any age. We report our diagnosis of a bronchogenic cyst by transoesophageal echocardiography. It was successfully excised surgically. This is the eleventh case published in the world literature.
