Importance: Active monitoring (AM) for low-risk ductal carcinoma in situ (DCIS) has been considered as a potential alternative to guideline-concordant care (GCC; inclusive of surgery with or without radiation). Reported data comparing patient-reported outcomes (PROs) between GCC and AM for DCIS are lacking.

Objective: To compare PROs at baseline and over time in patients with low-risk DCIS randomized to receive either AM or GCC.

Background: Delays in breast cancer diagnosis and treatment lead to worse survival and quality of life. Racial disparities in care timeliness have been reported, but few studies have examined access at multiple points along the care continuum (diagnosis, treatment initiation, treatment duration, and genomic testing).

Methods And Findings: The Carolina Breast Cancer Study (CBCS) Phase 3 is a population-based, case-only cohort (n = 2,998, 50% black) of patients with invasive breast cancer diagnoses (2008 to 2013).

Background: The heterogeneous biology of ductal carcinoma in situ (DCIS), as well as the variable outcomes, in the setting of numerous treatment options have led to prognostic uncertainty. Consequently, making treatment decisions is challenging and necessitates involved communication between patient and provider about the risks and benefits. We developed and investigated an interactive decision support tool (DST) designed to improve communication of treatment options and related long-term risks for individuals diagnosed with DCIS.

Article Synopsis
  • The study compares survival outcomes for three treatment options for ductal carcinoma in situ: breast-conserving surgery alone, breast-conserving surgery with radiation, and mastectomy.
  • Data was collected from a large sample of patients diagnosed between 2008 and 2014, with a median follow-up of about 68 months.
  • Results showed extremely high disease-specific survival rates (99.6% or higher) across all treatment groups with no significant differences, although breast-conserving surgery without radiation had lower overall survival compared to surgery with radiation in patients under 65.

Background: Epigenetic changes link medical, social, and environmental factors with cardiovascular and kidney disease and, more recently, with cancer. The mechanistic link between metabolic health and epigenetic changes is only starting to be investigated. In our in vitro and in vivo studies, we performed a broad analysis of the link between hyperinsulinemia and chromatin acetylation; our top "hit" was chromatin opening at H3K9ac.

Background: OncotypeDx is a prognostic and predictive genomic assay used in early-stage hormone receptor-positive, HER2- (HR+/HER2-) breast cancer. It is used to inform adjuvant chemotherapy decisions, but not all eligible women receive testing. We aimed to assess variation in testing by demographics and geography, and to determine whether testing was associated with chemotherapy.

Background: Studies have shown improved survival among individuals with cancer with higher levels of social support. Few studies have investigated social support and overall survival (OS) in individuals with advanced prostate cancer in an international cohort. We investigated the associations of marital status and living arrangements with OS among individuals with advanced prostate cancer in the International Registry for Men with Advanced Prostate Cancer (IRONMAN).

Background: Gastric cancer (GC) accounts for the greatest disparity in cancer mortality between Black and White Americans. Although clinical trials have shown that Helicobacter pylori (Hp) treatment reduces risk of GC, Hp testing and treatment is not consistently performed in the US, and may offer an opportunity to improve survival.

Methods: In a diverse retrospective cohort of 99 GC cases diagnosed at Duke University from 2002-2020 (57% Black; 43% white), we examined the association of Hp testing and treatment prior to or at cancer diagnosis with overall survival using Cox regression analyses to calculate adjusted hazards ratios (HRs) and 95% confidence intervals (CIs).

Background: In light of recent retrospective studies revealing evidence of disparities in access to medical technology and of bias in measurements, this narrative review assesses digital determinants of health (DDoH) in both technologies and medical formulae that demonstrate either evidence of bias or suboptimal performance, identifies potential mechanisms behind such bias, and proposes potential methods or avenues that can guide future efforts to address these disparities.

Approach: Mechanisms are broadly grouped into physical and biological biases (e.g.

Importance: Improvements in cancer outcomes have led to a need to better understand long-term oncologic and nononcologic outcomes and quantify cancer-specific vs noncancer-specific mortality risks among long-term survivors.

Objective: To assess absolute and relative cancer-specific vs noncancer-specific mortality rates among long-term survivors of cancer, as well as associated risk factors.

Design, Setting, And Participants: This cohort study included 627 702 patients in the Surveillance, Epidemiology, and End Results cancer registry with breast, prostate, or colorectal cancer who received a diagnosis between January 1, 2003, and December 31, 2014, who received definitive treatment for localized disease and who were alive 5 years after their initial diagnosis (ie, long-term survivors of cancer).

Article Synopsis
  • T-cell activity is suppressed in ER+ breast cancer when PD-1 binds PD-L1 or PD-L2, raising the need for better ways to predict who will respond to treatments like PD-1 inhibitors.
  • This study focused on measuring PD-L2 protein levels in patients with therapy-naive ER+ breast cancer and correlated these levels with progression-free survival (PFS) across two cohorts.
  • Results showed that high PD-L2 expression in cancer cells was linked to shorter PFS, suggesting that high PD-L2 levels can be an important marker to identify patients at greater risk of early recurrence.

Article Synopsis
  • Guidelines recommend annual imaging for women diagnosed with ductal carcinoma in situ (DCIS), yet adherence to these guidelines has not been fully assessed in recent years.
  • A study of over 12,500 women showed a decline in surveillance imaging adherence from 75% initially to only 52% participating consistently over five years, with lower rates observed among Black and Hispanic women compared to White women.
  • Women who engaged in surveillance imaging during the first year had a slightly higher rate of invasive cancer diagnosis over six years than those who did not participate in surveillance.

Purpose: Outcomes for patients with metastatic breast cancer (MBC) are continually improving as more effective treatments become available. Granular data sets of this unique population are lacking, and the standard method for data collection relies largely on chart review. Therefore, using electronic health records (EHR) collected at a tertiary hospital system, we developed and evaluated a computational phenotype designed to identify all patients with MBC, and we compared the effectiveness of this algorithm against the gold standard, clinical chart review.

Rationale And Objectives: Adoption of the Prostate Imaging Reporting & Data System (PI-RADS) has been shown to increase detection of clinically significant prostate cancer on prostate mpMRI. We propose that a rule-based algorithm based on Regular Expression (RegEx) matching can be used to automatically categorize prostate mpMRI reports into categories as a means by which to assess for opportunities for quality improvement.

Materials And Methods: All prostate mpMRIs performed in the Duke University Health System from January 2, 2015, to January 29, 2021, were analyzed.

Racist and discriminatory federal, state, and local housing policies significantly contribute to disparities in cardiovascular disease incidence and mortality for individuals that self-identify as Black or African American. Here we highlight three key housing policies - "redlining," zoning, and the construction of highways - which have wrought a powerful, sustained, and destructive impact on cardiovascular health in Black/African American communities. Redlining and highway construction policies have restricted access to quality health care, increased exposure to carcinogens such as PM, and increased exposure to extreme heat.
