HER-2 amplification + HR-positive

However, clinical implementation requires greater methodological standardization, validated predictive biomarkers, accessible diagnostic platforms, and dynamic monitoring strategies capable of capturing subtype evolution under therapeutic pressure. TNBC should therefore not be regarded as a single disease, but as a spectrum of biologically distinct and clinically evolving entities whose integrated characterization may be essential to improving outcomes in this historically poor-prognosis population.

Given that chemotherapy is still the cornerstone of TNBC treatment, understanding its impact on systemic and tumour immune cells is crucial for improving the effectiveness of combination therapies. This review will delve into the specific roles of TNBC chemotherapies on key immune cells during both tumour progression and regression.

Particular emphasis is placed on the translation of molecular diagnostics into clinical decision-making, including patient selection, resistance mechanisms, and sequencing strategies within evolving precision oncology frameworks. Ongoing clinical and translational research will be critical to refine combination strategies, overcome resistance mechanisms, and identify predictive biomarkers to further optimize patient outcomes.

Precision diagnostics now encompass next-generation sequencing (NGS)-based comprehensive genomic profiling, enabling identification of actionable alterations such as PIK3CA mutations, HER2 amplification, BRCA1/2 pathogenic variants, and NTRK fusions, each linked to approved therapeutic agents. The purpose of this review is to provide a comprehensive synthesis of current and emerging diagnostic modalities in breast cancer-from population-level screening to individualized molecular profiling-and to examine how integrative, multimodal diagnostic platforms are reshaping clinical decision-making in the era of precision medicine.

This case represents one of the longest reported intervals between initial remission and breast cancer recurrence, highlighting the prolonged biologic potential of dormant ER-positive tumor cells. Clinicians should maintain vigilance for recurrence even decades after treatment, particularly in hormone receptor-positive disease.

Our findings indicate that COL1A2 is associated with reduced chemotherapy sensitivity in HR+/HER2- breast cancer and may serve as a candidate biomarker to guide neoadjuvant taxane selection. This study provides a novel theoretical basis for optimizing neoadjuvant chemotherapy regimens in patients with advanced HR+/HER2- breast cancer.

This finding suggests that tasquinimod, an S100A9 inhibitor, could be a viable therapeutic option. Furthermore, the interaction between MMP11 and COL16A1 in stroma-rich regions suggests that cancer-associated fibroblasts may contribute to improved outcomes. Our study underscores the critical role of spatial gene expression analysis in elucidating the tumor microenvironment and its impact on prognosis in patients undergoing E+L treatment, thereby opening new avenues for targeted interventions.
