[Surgery or not on an atypical breast lesion? Taking anxiety into account in shared decision support from a prospective cohort of 300 patients].

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.

Prospective Multicenter Study Validate a Prediction Model for Surgery Uptake Among Women with Atypical Breast Lesions.

Background: Diagnosis of atypical breast lesions (ABLs) leads to unnecessary surgery in 75-90% of women. We have previously developed a model including age, complete radiological target excision after biopsy, and focus size that predicts the probability of cancer at surgery. The present study aimed to validate this model in a prospective multicenter setting.

Is a breast MRI possible and indicated in case of suspicion of breast cancer during lactation?

The paper tries to answer two questions: the safety of the injection of gadolinium during breastfeeding; the value of a breast MRI in the nursing mother if breast cancer is suspected. Recent Anglo-Saxon publications are in favour of continued breastfeeding following the injection of gadolinium. In fact, only a minute quantity of contrast product passes into the mother's milk, much less than the threshold recommended in paediatrics in the infant.

[MRI evaluation of residual breast carcinoma after neoadjuvant chemotherapy].

Purpose: This study aims to evaluate the sensibility and specificity of MRI in the detection and size measuring of residual breast cancer in patients treated with neoadjuvant chemotherapy before surgery.

Patients And Methods: This is a retrospective study of 32 women, who underwent breast MRI before and after neoadjuvant treatment. MRI has been confronted to surgical pathology results.

[Management system for patients requiring stereotactic macrobiopsies of the breast: report on 100 patients].

Purpose: The authors describe and evaluate the management system for patients requiring large core vacuum-assisted biopsies at a dedicated breast center. This process includes mandatory review of all requests by a multidisciplinary team.
