Recent Update on Nanocarrier(s) as the Targeted Therapy for Breast Cancer

Area of Science:

• Oncology
• Nanotechnology
• Drug Delivery Systems

Background:

• Current breast cancer therapies show limitations in effectiveness.
• Nanotechnology offers potential to improve cancer drug delivery.
• Nano-drug delivery systems (NDDS) can enhance treatment by optimizing drug targeting and release.

Purpose of the Study:

• To review recent advancements in nanocarriers for breast cancer chemotherapy.
• To discuss challenges associated with nanocarrier-based drug delivery.
• To explore future directions in this field.

Main Methods:

• Review of literature on nanocarriers for breast cancer treatment.
• Focus on strategies like optimizing physicochemical properties and modulating the tumor microenvironment.
• Examination of external stimuli-responsive nanocarriers, particularly ultrasound-triggered systems.

Main Results:

• Nanocarriers protect therapeutic agents from degradation and improve drug concentration at target sites.
• Ultrasound-triggered nanocarriers demonstrate advantages including non-invasiveness, specificity, and enhanced drug delivery.
• Despite benefits, challenges like poor permeability and low bioavailability persist.

Conclusions:

• Nanocarriers, especially ultrasound-triggered ones, represent a promising approach for breast cancer chemotherapy.
• Addressing current limitations is crucial for maximizing the potential of these advanced delivery systems.
• Further research is needed to optimize nanocarrier design and application in clinical settings.
