Association Between Surgery Preference and Receipt in Ductal Carcinoma In Situ After Breast Magnetic Resonance Imaging: An Ancillary Study of the ECOG-ACRIN Cancer Research Group (E4112).

Importance: Guiding treatment decisions for women with ductal carcinoma in situ (DCIS) requires understanding patient preferences and the influence of preoperative magnetic resonance imaging (MRI) and surgeon recommendation.

Objective: To identify factors associated with surgery preference and surgery receipt among a prospective cohort of women with newly diagnosed DCIS.

Design, Setting, And Participants: A prospective cohort study was conducted at 75 participating institutions, including community practices and academic centers, across the US between March 25, 2015, and April 27, 2016.

The use of neoadjuvant therapy increases the rate of breast conservation in men with locally advanced breast cancer.

Background: Male breast cancer (MBC) is often diagnosed at a later stage and with a more unfavorable tumor-to-breast ratio compared to women, prompting lower rates of breast conservation (BCT). We sought to assess the practice patterns of neoadjuvant therapy (NT) in MBC patients and the impact on BCT.

Methods: Men with nonmetastatic, invasive breast cancer were identified from the National Cancer Database.

Racial and socioeconomic disparities in breast cancer diagnosis and mortality in Pennsylvania.

Purpose: Many studies have demonstrated disparities in breast cancer (BC) incidence and mortality among Black women. We hypothesized that in Pennsylvania (PA), a large economically diverse state, BC diagnosis and mortality would be similar among races when stratified by a municipality's median income.

Methods: We collected the frequencies of BC diagnosis and mortality for years 2011-2015 from the Pennsylvania Cancer Registry and demographics from the 2010 US Census.

Preoperative Breast MRI for Newly Diagnosed Ductal Carcinoma in Situ: Imaging Features and Performance in a Multicenter Setting (ECOG-ACRIN E4112 Trial).

Background There are limited data from clinical trials describing preoperative MRI features and performance in the evaluation of mammographically detected ductal carcinoma in situ (DCIS). Purpose To report qualitative MRI features of DCIS, MRI performance in the identification of additional disease, and associations of imaging features with pathologic, genomic, and surgical outcomes from the Eastern Cooperative Oncology Group-American College of Radiology Imaging Network (ECOG-ACRIN) E4112 trial. Materials and Methods Secondary analyses of a multicenter prospective clinical trial from the ECOG-ACRIN Cancer Research Group included women with DCIS diagnosed with conventional imaging techniques (mammography and US), confirmed via core-needle biopsy (CNB), and enrolled between March 2015 and April 2016 who were candidates for wide local excision (WLE) based on conventional imaging and clinical examination results.

Institutions Treating Breast Cancer Patients of a Low Socioeconomic Status Achieve Multidisciplinary Quality Standards at Lower Rates.

Background: The National Accreditation Program of Breast Centers (NAPBC) certifies institutions that provide quality breast care. Whereas low socioeconomic status (SES) has a negative impact on patient outcomes, it is unknown whether an institution's patient SES mix is associated with meeting NAPBC standards.

Methods: All institutions submitting at least 100 breast cancer patients to the National Cancer Database (2006-2017) were ranked based on the patients' insurance status, income, and education.

Association of Magnetic Resonance Imaging and a 12-Gene Expression Assay With Breast Ductal Carcinoma In Situ Treatment.

Importance: Advanced diagnostics, such as magnetic resonance imaging (MRI) and gene expression profiles, are potentially useful to guide targeted treatment in patients with ductal carcinoma in situ (DCIS).

Objectives: To examine the proportion of patients who converted to mastectomy after MRI and the reasons for those conversions and to measure patient adherence to radiotherapy guided by the 12-gene DCIS score.

Design, Setting, And Participants: Analysis of a prospective, cohort, nonrandomized clinical trial that enrolled women with DCIS on core biopsy who were candidates for wide local excision (WLE) from 75 institutions from March 25, 2015, to April 27, 2016, through the Eastern Cooperative Oncology Group-American College of Radiology Imaging Network trial E4112.

Diagnosis, treatment, and management of breast cancer in previously augmented women.

Augmentation mammaplasty is rapidly becoming one of the most frequently performed cosmetic surgeries. However, as the augmented patient population ages, major concerns associated with the screening, diagnosis and treatment of breast cancer are being realized. Although current evidence convincingly indicates that breast implants do not play a role in inducing localized or systemic disease, particularly breast cancer, recent studies have shown implants not only reduce the sensitivity of mammography, but interfere with mammographic detection, possibly leading to delayed breast cancer diagnosis.
