Photothermal Combination Therapy for Metastatic Breast Cancer: A New Strategy and Future Perspectives

Area of Science:

• Oncology
• Biomedical Engineering
• Nanotechnology

Background:

• Metastatic breast cancer (MBC) presents significant challenges due to tumor heterogeneity and multidrug resistance.
• Conventional therapies have limitations in effectively treating aggressive and fatal MBC cases.

Purpose of the Study:

• To review recent advances in nanomaterial-based photothermal therapy (PTT) for MBC treatment.
• To evaluate the potential of PTT platforms in overcoming therapeutic limitations for metastatic breast cancer.

Main Methods:

• Comprehensive literature analysis of nanomaterials engineered for targeted PTT.
• Examination of PTT mechanisms, synergistic applications, and targeting of metastatic niches.

Main Results:

• Nanotechnology-enabled PTT offers spatiotemporal precision, efficient tumor ablation, and reduced systemic toxicity.
• Integrated PTT enhances therapeutic outcomes in multimodal strategies, with advancements in imaging and drug delivery.
• Biocompatibility, safety, and clinical translation remain challenges.

Conclusions:

• Nanomaterial-assisted PTT demonstrates significant potential for improving MBC treatment efficacy.
• Future research should focus on optimizing imaging, minimizing adverse effects, and addressing translational hurdles for clinical integration.
