Summary

Breast cancer remains one of the most prevalent malignancies worldwide, with substantial heterogeneity across molecular subtypes and clinical behavior. Advances in targeted and precision medicine have significantly transformed therapeutic strategies, providing more individualized treatment approaches and improving patient outcomes. Topics of interest include targeted therapies against HER2, PI3K/AKT/mTOR, and other actionable pathways, immune checkpoint inhibitors, antibody–drug conjugates, and endocrine resistance mechanisms. The integration of CDK4/6 inhibitors with endocrine therapy has established a new standard of care in hormone receptor–positive disease, while immunotherapy has expanded options in triple-negative breast cancer, guided by predictive biomarkers such as PD-L1 expression. In addition, genomic and molecular profiling is increasingly applied to identify patient subgroups most likely to benefit from specific interventions, supporting biomarker-driven decision-making. Ongoing clinical trials are further refining sequencing strategies, novel combinations, and precision-based regimens. This special issue aims to showcase original research, clinical trials, and comprehensive reviews that highlight recent advances in targeted and precision medicine, with the ultimate goal of enhancing survival, reducing treatment burden, and improving quality of life for patients with breast cancer.

    Abstract Background: Breast cancer is the leading cause of cancer-related deaths in women, primarily due to distant metastasis. Metabolic reprogramming plays a critical role in tumor growth and spread, but the metabolic mechanisms underlying metastasis in breast cancer remain unclear. The primary objective of this study is to identify molecular targets mediating breast cancer progression and to evaluate whether targeting the metabolic reprogramming represents a potential therapeutic strategy. Methods: To uncover key metabolic regulators involved in breast cancer progression, we analyzed high-throughput RNA sequencing data and identified Paired Like Homeodomain 1 (PITX1) as a frequently upregulated… More >

    Microbiome and Response to Therapy in Triple Negative Breast Cancer: A Systematic Review

    Abstract Objectives: Triple-negative breast cancer (TNBC) accounts for approximately 15% of all invasive breast cancers and is characterized by aggressive behavior, limited therapeutic options, and poor clinical outcomes. Due to the absence of hormone receptors and HER2 expression, systemic treatment relies predominantly on chemotherapy, which is associated with high rates of early recurrence and mortality. Emerging evidence suggests that alterations in the microbiome can contribute to TNBC progression and influence therapeutic response, particularly affecting the efficacy of chemotherapy and immunotherapy through immune-mediated mechanisms; however, its role in TNBC remains incompletely understood. This systematic review aims to explore… More >

    Long Non-Coding RNAs in HER2-Positive Breast Cancer: From Resistance Mechanisms to Translational Potential

    Oncology Research, DOI:10.32604/or.2026.075346

    Abstract Long non-coding RNAs (lncRNAs) have emerged as key regulators of drug resistance in human epidermal growth factor receptor 2 (HER2)-positive breast cancer, a subtype in which both intrinsic and acquired resistance to HER2-targeted therapies remain major clinical challenges. Although mechanistic studies have begun to reveal how lncRNAs modulate signaling pathways, interact with microRNAs, and influence the tumor microenvironment, dedicated investigations in HER2-positive disease are still limited. This review synthesizes current evidence across epigenetic, transcriptional, and post-transcriptional mechanisms of resistance, including competing endogenous RNA (ceRNA) networks, RNA-binding protein interactions, and exosome-mediated intercellular communication. Particular emphasis is… More >
