TL;DR

The integration of TME-targeted and individualized therapeutic strategies may offer promising prospects toward achieving durable clinical outcomes in breast cancer treatment.

Abstract

Among the leading causes of cancer-related morbidity and mortality worldwide, breast cancer presents fundamental challenges, such as tumor heterogeneity and therapeutic resistance. The tumor microenvironment (TME), comprising stromal components, signaling molecules, immune cells, and the extracellular matrix, has demonstrated a pivotal role in tumor progression, invasion, and therapeutic response. In this review, we comprehensively summarize the state-of-the-art and novel therapeutic strategies developed to reprogram the TME in breast cancer. From clinically established treatments, such as endocrine therapy, antibody-drug conjugates, and HER2-targeted therapy, to emerging agents, such as siRNA-mediated gene silencing, nanomedicine, and immunotherapy, each class of therapeutic strategy, along with the corresponding clinical and preclinical outcomes, is detailed by category. The evidence for and impact of TME heterogeneity and differences in molecular subtypes on therapeutic efficiency are highlighted, and biomarker-guided patient stratification is further emphasized to support precision therapy. Mechanistic challenges, such as immunosuppression, ECM remodeling, and hypoxia-associated resistance, were analyzed, and mechanistic conflicts or synergistic interactions between strategies were identified. Tumor microbiome modification and AIdriven discovery of novel biomarkers are presented as emerging perspectives in TME-targeting therapy. Despite significant advances, translation barriers, such as the lack of predictive biomarkers and the divergence in therapeutic outcomes between patients and animal models, are critically reviewed and discussed. The integration of TME-targeted and individualized therapeutic strategies may offer promising prospects toward achieving durable clinical outcomes in breast cancer treatment.

Ovarian cancer tumor immune microenvironment and its clinical trial implications

Ovarian cancer is the most lethal gynecologic malignancy, primarily because of late-stage diagnosis, rapid disease progression, and marked molecular and immunologic heterogeneity. It remains the leading cause of gynecologic cancer-related death, affecting approximately 1 in 70 women in developed countries over their lifetimes. Tumor development and progression are orchestrated within the tumor immune microenvironment, a dynamic and complex structural niche that supports malignant transformation and immune evasion of the tumor. In this narrative educational review, we aim to provide a comprehensive overview of recent advances in the understanding of ovarian cancer pathogenesis, the molecular mechanisms driving tumor progression, and the multifaceted role of the immune system in disease development and therapeutic response. Moreover, we summarize recent clinical trials targeting key molecular drivers and components of the tumor immune microenvironment, including immunotherapeutic and targeted approaches. Personalized medicine, guided by integrative genomic and transcriptomic profiling, has become increasingly vital for patient stratification and treatment selection. Ultimately, a shift toward highly individualized, mechanism-based therapeutic strategies is essential to improve clinical outcomes and survival in ovarian cancer.

The tumor microenvironment in pancreatic cancer: from composition to therapeutic targeting

Abstract Pancreatic cancer, predominantly represented by Pancreatic Ductal Adenocarcinoma (PDAC), is one of the most frequent and deadly types of cancer. In contrast with other types of cancer, for which advances in prevention, early detection, and treatment have contributed to decreasing incidence and mortality, PDAC continues to be rarely diagnosed at early stages of the disease and exhibits a poor prognosis. As a consequence, therapeutic efficacy remains limited, which is reflected in high mortality. Therefore, the development of novel and effective therapeutic strategies against PDAC is urgent. However, a major component limiting therapeutic efficacy is the highly complex PDAC tumor microenvironment (TME), which is composed of cancer-associated fibroblasts, immunosuppressive cells, cancer stem cells, and a dense extracellular matrix, a structural and biochemical scaffold that sustains tumor development and influences several PDAC phenotypes including metabolism, immune infiltration, metastasis, and therapeutic response. The present review focuses on and discusses the key components of the PDAC TME, with particular emphasis on ECM remodeling, stromal components, their impact on tumor progression and therapeutic resistance, and emerging strategies to target these processes.

Advances in Molecular Subtype-Based Precision Therapy and Strategies to Overcome Resistance in Breast Cancer

Breast cancer is a leading cause of cancer -related morbidity and mortality, characterized by significant biological and molecular heterogeneity. Molecular subtypes —including luminal A, luminal B, HER2 - enriched, and triple -negative—inform prognosis and guide prec ision therapies. Despite advances with endocrine agents, HER2-targeted therapies, PARP inhibitors, and immune checkpoint inhibitors, therapeutic resistance remains a major challenge, driven by intratumoral heterogeneity, cancer stem cell plasticity, and tumor microenvironmental factors. Genomic profiling, liquid biopsies, combination and adaptive strategies, and next-generation antibody-drug conjugates are emerging to overcome resistance and optimize outcomes. Additionally, novel immunotherapies and artific ial intelligence (AI) –assisted decision -making support individualized treatment selection. This review summarizes recent advances, from molecular characterization to precision-guided interventions and strategies to counteract resistance, and emphasizes the integration of biological insights into personalized breast cancer management.
