Regardless of advances in detection and treatment, breast cancer affects about 1.5 million women all over the world. Since the last decade, genome-wide association studies (GWAS) have been extensively conducted for breast cancer to define the role of miRNA as a tool for diagnosis, prognosis and therapeutics. MicroRNAs are small, non-coding RNAs that are associated with the regulation of key cellular processes such as cell multiplication, differentiation, and death. They cause a disturbance in the cell physiology by interfering directly with the translation and stability of a targeted gene transcript. MicroRNAs (miRNAs) constitute a large family of non-coding RNAs, which regulate target gene expression and protein levels that affect several human diseases and are suggested as the novel markers or therapeutic targets, including breast cancer. MicroRNA (miRNA) alterations are not only associated with metastasis, tumor genesis but also used as biomarkers for breast cancer diagnosis or prognosis. These are explained in detail in the following review. This review will also provide an impetus to study the role of microRNAs in breast cancer.

Adjuvant taxane-based chemotherapy treatment in older patients with early breast cancer: A pooled analysis of five phase III trials from the Hellenic Oncology Research Group.
J Geriatr Oncol
January 2025
Hellenic Oncology Research Group (HORG), 55, Lomvardou str, 11470 Athens, Greece.
Introduction: The use of taxanes in the adjuvant setting of early breast cancer (BC) confers survival benefits, however, their role in older patients merits further study. This retrospective pooled analysis of randomized controlled trials conducted by the Hellenic Oncology Research Group (HORG) aims to assess the efficacy and safety of taxane-based adjuvant chemotherapy in older women with BC.
Materials And Methods: Five phase III trials containing a taxane, conducted by HORG between 1995 and 2013, were included in a patient-data pooled analysis.
Evaluating the Accuracy of Relative Value Unit and Operative Time Changes in Breast Reconstruction.
Plast Reconstr Surg
December 2024
Plastic and Reconstructive Surgery Service, Department of Surgery, Memorial Sloan Kettering Cancer Center, New York, NY.
Background: As part of the 2021 changes to breast reconstruction CPT codes, the Relative Value Scale Update Committee (RUC) recommended adjustments to work RVUs (wRVUs) based on newly surveyed intraoperative times. Our objective was to gauge the accuracy of operative time and wRVU adjustments using national data as a benchmark.
Methods: We queried the National Surgical Quality Improvement Program (NSQIP) database for operative times from 2005-2021 for reevaluated CPT codes.
Effects of White Noise Intervention on Sleep Quality and Immunological Indicators of Patients with Breast Cancer Undergoing Neoadjuvant Chemotherapy.
Noise Health
January 2025
Department of Geriatric Health Internal Medicine, Qingdao Municipal Hospital, Qingdao 266000, China.
Objective: Evaluate the effect of white noise intervention on sleep quality and immunological indicators of patients with breast cancer undergoing neoadjuvant chemotherapy (NAC).
Methods: From January 2020 to December 2022, 104 newly diagnosed female patients (the number of people who met the inclusion criteria) with breast cancer who were confirmed to be preoperative NAC by puncture pathology were selected for a randomised single-blind trial. The patients were randomly divided into an observation group and a control group, with 52 cases in each group.
Trastuzumab-Pertuzumab Plus Eribulin or Taxane as First-Line Chemotherapy for Human Epidermal Growth Factor 2-Positive Locally Advanced/Metastatic Breast Cancer: The Randomized Noninferiority Phase III EMERALD Trial.
J Clin Oncol
January 2025
Department of Breast Surgery, Graduate School of Medicine, Kyoto University, Kyoto, Japan.
Purpose: Trastuzumab-pertuzumab (HP) plus taxane is a current standard first-line therapy for recurrent or metastatic human epidermal growth factor 2 (HER2)+ breast cancer (BC). We investigated noninferiority of eribulin to a taxane when combined with dual HER2 blockade as first-line systemic treatment for locally advanced/metastatic HER2+ BC.
Methods: In the phase III EMERALD trial (target sample size, 480; ClinicalTrials.
Healthcare providers' (HCPs) perspectives in initiating discussion on mammogram screening, and their perceived barriers and enablers to screening in women-A qualitative study.

Background: Breast cancer is the most common cancer in women, and mammogram screening can reduce breast cancer mortality. Healthcare providers' perspectives can have an impact on encouraging females to attend mammogram screening.
Objective: To understand healthcare providers' (HCPs) perspectives in initiating discussion on mammogram screening, and their perceived barriers and enablers to screening in women.
