Background: Neoadjuvant chemotherapy (NACT) is a treatment option for breast cancer patients that allows for the assessment of tumor response during treatment. This information can be used to adjust treatment and improve outcomes. However, the optimal imaging modalities and parameters for assessing tumor response to NACT are not well established.

The COVID-19 Pandemic Impact on Breast Cancer Diagnosis: A Retrospective Study.
Rev Bras Ginecol Obstet
September 2022
Objective: This study aimed to evaluate the diagnostic profile of breast cancer cases during the coronavirus disease 2019 (COVID-19) pandemic compared with the previous year.
Methods: It is a retrospective study of cases diagnosed by a reference service in the public health system of Campinas, SP, Brazil. Two periods were analyzed: March to October 2019 (preCOVID period) and March to October 2020 (COVID-period).
Introduction: Epidemiological studies have shown that some hormonal contraceptive methods are associated with increased breast cancer risk, especially if used over long periods. Our objective was to conduct a systematic review and meta-analysis of the literature on the risk of breast cancer development in women using the 52-mg levonorgestrel-releasing intrauterine system (LNG-IUS).
Material And Methods: We performed a thorough review of peer-reviewed publications from 10 January 1999, through 31 July 2019, using combinations of search terms for breast cancer risk and LNG-IUS in the Medline, EMBASE, LILACS (Latin American and Caribbean Health Sciences Literature), and Scielo databases.
Background: As the most incident tumor among women worldwide, breast cancer is a heterogeneous disease. Tremendous efforts have been made to understand how tumor characteristics as histological type, molecular subtype, and tumor microenvironment collectively influence disease diagnosis to treatment, which impact outcomes. Differences between populations and environmental and cultural factors have impacts on the origin and evolution of the disease, as well as the therapeutic challenges that arise due to these factors.

Eur J Radiol
April 2019
Objectives: To evaluate the diagnostic performance and the clinical benefit of Shear-Wave Elastography - Virtual Touch Imaging Quantification (SWE-VTIQ) as a complement to ultrasonography (US).
Methods: From October 2016 through Jun 2017, B-mode US and SWE-VTIQ were prospectively performed in 396 breast masses in 357 women who consented to undergo this study. Quantitative elastography values were recorded: V (maximum elasticity), V (median elasticity), V (ratio of V and surrounding parenchyma) and V (ratio of V and surrounding parenchyma).
Objective: To evaluate the natural history and outcome predictors in familial mesial temporal lobe epilepsy (FMTLE).
Methods: We conducted a longitudinal study of 103 individuals from 17 FMTLE families (mean follow-up: 7.6 years).
Introduction: Studies have shown progressive cerebral damage in patients with refractory mesial temporal lobe epilepsy (MTLE). However, this has not been demonstrated in benign forms of MTLE such as familial mesial temporal lobe epilepsy (FMTLE).
Purpose: To evaluate progression of hippocampal atrophy (HA) in patients with sporadic mesial temporal lobe epilepsy (SMTLE) and FMTLE by longitudinal Magnetic resonance images (MRIs) acquired with at least 7 months of interval.
