Validation of the Mirai model for predicting breast cancer risk in Mexican women.

Objectives: To validate the performance of Mirai, a mammography-based deep learning model, in predicting breast cancer risk over a 1-5-year period in Mexican women.

Methods: This retrospective single-center study included mammograms in Mexican women who underwent screening mammography between January 2014 and December 2016. For women with consecutive mammograms during the study period, only the initial mammogram was included.

Ductal carcinoma in situ within a fibroadenoma: A case report and review of literature.

Background: Fibroadenoma (FA) is the most common tumor found in young women, although it can occur in any age group. Ductal carcinoma in situ (DCIS) that is confined in a FA is rare; it is most frequently reported as an incidental finding.

Case Summary: We report a case of DCIS within a FA in a 46-year-old female without cancer-related personal and family histories.

High-risk lesions of the breast: concurrent diagnostic tools and management recommendations.

Breast lesions with uncertain malignant behavior, also known as high-risk or B3 lesions, are composed of a variety of pathologies with differing risks of associated malignancy. While open excision was previously preferred to manage all high-risk lesions, tailored management has been increasingly favored to reduce overtreatment and spare patients from unnecessary anxiety or high healthcare costs associated with surgical excision. The purpose of this work is to provide the reader with an accurate overview focused on the main high-risk lesions of the breast: atypical intraductal epithelial proliferation (atypical ductal hyperplasia), lobular neoplasia (including the subcategories lobular carcinoma in situ and atypical lobular hyperplasia), flat epithelial atypia, radial scar and papillary lesions, and phyllodes tumor.

Radiogenomics analysis identifies correlations of digital mammography with clinical molecular signatures in breast cancer.

In breast cancer, well-known gene expression subtypes have been related to a specific clinical outcome. However, their impact on the breast tissue phenotype has been poorly studied. Here, we investigate the association of imaging data of tumors to gene expression signatures from 71 patients with breast cancer that underwent pre-treatment digital mammograms and tumor biopsies.

Her-2 positive mucinous carcinoma breast cancer, case report.

Introduction: Mucinous carcinoma is a variant of invasive breast carcinomas that accounts for 2% of them and has a better prognosis in contrast to the non-specific invasive carcinoma. They regularly are positive for estrogen and progesterone receptors and, generally, they do not overexpress HER2. When HER2 is positive, the first line treatment is trastuzumab; although the resistance is 52-89% for the non-specific carcinoma, it has been described just once in mucinous carcinoma.

[Detection of invasive breast lobular carcinoma by image analysis: comparison between mammography and ultrasound].

Background: Early detection of lobular cancer has for long implied a challenge for diagnostic imaging due to the peculiar histology it presents that makes clinical and radiology detection rather difficult.

Objective: The aim of our study was to compare the sensitivity and specificity of mammography and ultrasound for the diagnosis of invasive breast lobular carcinoma.

Material And Methods: This is a retrospective study of women with histopathological diagnosis of invasive breast lobular carcinoma in the period between September 2006 and August 2009.
