Tumor therapy: targeted drug delivery systems

Area of Science:

• Oncology
• Nanotechnology
• Pharmacology

Background:

• Targeted drug delivery systems (TDDSs) are increasingly recognized for their potential in cancer therapy.
• Current research focuses on optimizing TDDSs for improved tumor targeting and therapeutic outcomes.
• Understanding the mechanisms of TDDSs is crucial for advancing cancer treatment strategies.

Purpose of the Study:

• To review the targeting mechanisms of TDDSs for tumor therapy.
• To highlight active targeting strategies for various cellular components within tumors.
• To present recent advancements and clinical potential of TDDSs in preclinical and clinical trials.

Main Methods:

• Literature review of targeted drug delivery systems in tumor therapy.
• Analysis of passive and active targeting strategies employed by TDDSs.
• Compilation of recent TDDSs undergoing preclinical and clinical evaluation.

Main Results:

• TDDSs utilize both passive (e.g., enhanced permeability and retention effect) and active targeting mechanisms.
• Active targeting strategies focus on tumor cell membranes and intracellular organelles.
• Several TDDSs demonstrate significant clinical potential in ongoing trials.

Conclusions:

• TDDSs represent promising nanoplatforms for advanced tumor therapy.
• Optimization of targeting strategies is essential for maximizing therapeutic efficiency.
