Contrast-enhanced mammography predicts pathological response after neoadjuvant chemotherapy in locally advanced breast cancer.

Introduction: Recently, contrast-enhanced mammography (CEM) has emerged as a reliable alternative to breast magnetic resonance imaging (MRI) for the assessment of pathological response in breast cancer patients. Our study sought to determine the diagnostic accuracy of CEM to predict pathological complete response (pCR) in patients who received neoadjuvant chemotherapy (NACT).

Methods: We retrieved the medical records of patients who underwent NACT at our institution.

Screen-detected breast cancer is associated with better prognosis and survival compared to self-detected/symptomatic cases in a Chilean cohort of female patients.

Purpose: The implementation of national breast cancer (BC) screening programs in Latin America has been rather inconsistent. Instead, most countries have opted for "opportunistic" mammogram screenings on the population at risk. Our study assessed and compared epidemiological, clinical factors, and survival rates associated with BC detected by screening (SDBC) or self-detected/symptomatic (non-SDBC) in Chilean female patients.

Survival rates of advanced estrogen-receptor positive breast cancer. Analysis of 211 cases.

Background: About 80% of breast cancer (BC) cases express estrogen receptor (ER), which has been correlated with good prognosis and response to estrogen deprivation Aim: To characterize ER positive advanced BC (ABC) patients treated at our institution assessing the impact of clinical pre-sentation (stage IV, de novo disease at diagnosis versus systemic recurrence) and BC subtype on survival rates.

Material And Methods: We evaluated 211 ER+ advanced BC (ABC) patients, treated between 1997 and 2017.

Results: The median overall survival (OS) was 37 months.

Mammography correlates to better survival rates in breast cancer patients: a 20-year experience in a University health institution.

Breast cancer (BC) is the most common malignancy in women. We retrieved medical records from >2,000 Chilean BC patients over the 1997-2018 period. The objective was to assess changes in clinical presentation or prognosis of our patients throughout these 20 years of practice.

The Neutrophil to Lymphocyte Ratio Predicts the Response to Neoadjuvant Chemotherapy in Luminal B Breast Cancer.

Objective: Tumor response to neoadjuvant chemotherapy (NAC) in breast cancer (BC) patients is a predictor for overall survival. The aim of our study was to determine a relationship between the neutrophil to lymphocyte ratio (NLR) prior to NAC, BC subtypes and the probability of a pathologic complete response (pCR). Materials and Methods: Medical records were collected retrospectively from Centro de Cancer at Red Salud UC-Christus.

Breast lesions with atypia in percutaneous biopsies, managed with surgery in the last 10 years.

Introduction: The optimal management of breast lesions with atypia (BLA), detected in percutaneous biopsies after screening mammograms, is a controversial issue. The aim of this paper is to compare histological diagnosis by percutaneous biopsy with the results of the surgical biopsy of these lesions and to analyse the changes to clinical approach this would imply.

Method: A retrospective study was carried out on patients operated on between June 2007 and June 2017 with a diagnosis of BLA.

[Survival of patients with advanced HER2+ breast cancer. Analysis of a cancer center database].

Background: HER2+ breast cancer (BC) subtype overexpresses the Human Epidermal growth factor Receptor type-2 (HER2) and is characterized by its aggressiveness and its high sensitivity to monoclonal antibody-based HER2-targeted therapies.

Aim: To assess the prognosis and evaluate the impact of novel anti-HER2 therapies on advanced HER2+ BC patients treated at our institution over the last decades.

Material And Methods: Analysis of the patient database at a cancer center of a university hospital.

[Contrast-enhanced spectral mammography. Experience in 465 examinations].

Background: Contrast-enhanced spectral mammography or "contrast mammography" has a better cost effectiveness than breast magnetic resonance for confirmation of suspicious lesions detected on breast screening programs.

Aim: To report the experience of a single center in Santiago.

Material And Methods: All patients referred for contrast mammography between July 2015 and October 2017 were studied.

Clinico-Pathologic Subtypes of Breast Cancer Primary Tumors Are Related to Prognosis after Recurrence.

Background: Pathological factors, based mainly on immunohistochemistry (IHC) and histological differentiation, are mostly used to differentiate breast cancer (BC) subtypes. Our present aim was to describe the characteristics and survival of a relapsing BC patient cohort based on clinico-pathologic subtypes determined for the primary tumors. Methods: We used a clinico- pathological definition of BC subtypes based on histological grade (HG), estrogen receptor (ER), progesterone receptor (PgR),and epidermal growth factor receptor type 2 (HER2) expression assessed by IHC.

Immunoglobulin G4 -related Sclerosing Mastitis: AIRP Best Cases in Radiologic-Pathologic Correlation.

Editor's Note.-RadioGraphics continues to publish radiologic-pathologic case material selected from the American Institute for Radiologic Pathology (AIRP) "best case" presentations. The AIRP conducts a 4-week Radiologic Pathology Correlation Course, which is offered five times per year.

Breast cancer and pregnancy: a comparative analysis of a Chilean cohort.

Introduction: Recent reports show that pregnancy-associated breast cancer (PABC) survival is similar to that of non-pregnant young patients. We evaluate the characteristics and prognosis of PABC patients treated in our cancer centre.

Patients And Methods: We identified patients with invasive PABC who were treated between 1999 and May 2013 and compared their characteristics with a no PABC cohort of similar age.

Enhancement of visual perception with use of dynamic cues.

Unlabelled: Institutional review board approval and signed informed consent were not needed, as medical images included in public databases were used in this study. The purpose of this study was to improve the detection of microcalcifications on mammograms and lung nodules on chest radiographs by using the dynamic cues algorithm and the motion and flickering sensitivity of the human visual system (HVS). Different sets of mammograms from the Mammographic Image Analysis Society database and chest radiographs from the Japanese Society of Radiological Technology database were presented statically, as is standard, and in a video sequence generated with the dynamic cues algorithm.
