Recent Advances in Targeted Drug Delivery Strategy for Enhancing Oncotherapy

Area of Science:

• Oncology
• Nanotechnology
• Pharmacology

Background:

• Targeted drug delivery enhances oncotherapy effectiveness and reduces side effects on normal tissues.
• Nanocarriers are key in delivering therapeutics to tumor sites via passive and active targeting mechanisms.
• Significant research advances have been made in targeted drug delivery for cancer treatment.

Purpose of the Study:

• To review recent targeted drug delivery strategies and technologies for enhancing oncotherapy.
• To examine passive and active targeting strategies using nanocarriers for tumor therapy.
• To compare and combine passive and active targeting approaches, discussing challenges and future prospects.

Main Methods:

• Review of recent literature on targeted drug delivery in oncotherapy.
• Analysis of nanocarrier-based passive targeting (enhanced permeability and retention effect).
• Analysis of nanocarrier-based active targeting (receptor-mediated).

Main Results:

• Nanocarriers facilitate drug delivery to tumors through EPR-mediated passive targeting and receptor-mediated active targeting.
• Both passive and active targeting strategies show promise in enhancing tumor therapy.
• Comparison and combination of these strategies offer potential for synergistic effects.

Conclusions:

• Targeted drug delivery via nanocarriers is a crucial strategy for improving oncotherapy outcomes.
• Further research into the challenges and synergistic combinations of passive and active targeting is warranted.
• Future prospects include optimizing nanocarrier design and targeting mechanisms for advanced cancer treatment.
