In the UNIRAD phase III trial, evening intake of tamoxifen was previously associated with improved disease-free survival (DFS), while no timing effect was observed for aromatase inhibitors. This sub-study evaluated whether the timing of everolimus intake affects DFS in patients receiving adjuvant endocrine therapy (ET). A total of 1278 patients with high-risk HR+/HER2- early breast cancer were randomized to receive adjuvant ET with either placebo or everolimus.

This manuscript critically examines the challenges associated with the design and conduct of academic global breast cancer trials outside the influence of pharmaceutical companies, leveraging insights from the Breast International Group (BIG). In the past 4 decades significant declines in breast cancer mortality have occurred, partly related to industry-academic clinical and translational partnerships with long term study follow up. However, in the past decade these partnerships have largely uncoupled.

Objectives: Adjuvant trastuzumab in combination with chemotherapy has significantly improved survival in patients with HER2-positive early breast cancer but, since introduction in 2005, the 12 months duration has been questioned and trials have tested shorter durations.

Methods And Analysis: A systematic review and meta-analysis using individual patient data (IPD) (when available) from non-inferiority trials of reduced duration trastuzumab was carried out according to PRISMA-IPD guidelines. Primary outcome was invasive disease-free survival (IDFS); secondary outcomes were distant relapse-free survival (DRFS) and overall survival (OS).

Background: Phage therapy is being reconsidered as a valuable approach to combat antimicrobial resistance. We recently established a personalized phage therapy pipeline in healthy volunteers, where therapeutic phages were isolated from individuals' skin microbiota. In this study, we aim to validate this pipeline in end-stage heart failure patients supported by left ventricular assist devices (LVADs), focusing on phages targeting , a common pathogen responsible for LVAD infections.

Breast cancer (BC) represents a heterogeneous ecosystem and elucidation of tumor microenvironment components remains essential. Our study aimed to depict the composition and prognostic correlates of immune infiltrate in early BC, at a multiplex and spatial resolution. Pretreatment tumor biopsies from patients enrolled in the EORTC 10994/BIG 1-00 randomized phase III neoadjuvant trial (NCT00017095) were used; the CNN11 classifier for H&E-based digital TILs (dTILs) quantification and multiplex immunofluorescence were applied, coupled with machine learning (ML)-based spatial features.

The transplantation of human neurons into the central nervous system (CNS) offers transformative opportunities for modeling neurodegenerative diseases in vivo. This study evaluated the survival, integration, and functional properties of cryopreserved forebrain GABAergic neurons (iGABAs) derived from human induced pluripotent stem cells (iPSCs) across three species used in translational research. iGABAs were stereotactically injected into the striatum of Sprague-Dawley rats, immunodeficient RNU rats, R6/2 Huntington's disease (HD) mice, wild-type controls, and Cynomolgus monkeys.

Residual Cancer Burden (RCB) after neoadjuvant chemotherapy (NAC) is validated to predict event-free survival (EFS) in breast cancer but has not been studied for invasive lobular carcinoma (ILC). We studied patient-level data from a pooled cohort across 12 institutions. Associations between RCB index, class, and EFS were assessed in ILC and non-ILC with mixed effect Cox models and multivariable analyses.

Background: The EORTC QLQ-BR23, published in 1996, was one of the first disease-specific questionnaires to assess health-related quality of life (HRQoL) in patients with breast cancer (BC). In the last decades, major changes in BC treatment have occurred, requiring an update of this module. The results of the Phase 1-3 of the study were published in 2019.

Background: The frequency of mammographic surveillance for women after diagnosis of breast cancer varies globally. The aim of this study was to evaluate whether less than annual mammography was non-inferior in terms of breast cancer-specific survival in women aged 50 years or older.

Methods: Mammo-50 was a multicentre, randomised, phase 3 trial of annual versus less frequent mammography (2-yearly after conservation surgery; 3-yearly after a mastectomy) for women aged 50 years or older at initial diagnosis of invasive or non-invasive breast cancer and who were recurrence free 3 years post curative surgery.

Importance: Triple-negative breast cancer is an aggressive subtype with a high incidence in young patients, a high incidence in non-Hispanic Black women, and a high risk of progression to metastatic cancer, a devastating sequela with a 12- to 18-month life expectancy. Until recently, one strategy for treating early-stage triple-negative breast cancer was chemotherapy after surgery. However, it was not known whether the addition of immune therapy to postsurgery chemotherapy would be beneficial.

Human epidermal growth factor receptor 2 (HER2) overexpression and/or ERBB2 gene amplification occurs in approximately 15-20% of breast cancers and is associated with poor prognosis. While the introduction of HER2-targeted therapies has significantly improved survival in patients with HER2-positive metastatic breast cancer, the incidence of brain metastases has increased due to patients living longer. Current recommendations sequence treatments by line of therapy, as well as by the status of brain metastases in patients with HER2-positive breast cancer.
