Abstract:
Targeting nanoparticles to cancers for improved therapeutic efficacy and decreased side effects remains a popular concept in the past decades. Although the enhanced permeability and retention effect serves as a key rationale for all the currently commercialized nanoformulations, it does not enable uniform delivery of nanoparticles to all tumorous regions in all patients with sufficient quantities. Also, the increase in overall survival is often modest. Many factors may influence the delivering process of nanoparticles, which must be taken into consideration for the promise of nanomedicine in patients to be realized. Herein, we review the mechanisms and influencing factors during the delivery of cancer therapeutics and summarize current strategies that have been developed for the fabrication of smart drug delivery systems.
Insights
Nanoparticle drug delivery for cancer shows promise but faces challenges in uniform tumor targeting and modest survival benefits. Optimizing nanoparticle delivery systems is crucial for realizing nanomedicine
Area of Science:
- Nanomedicine
- Oncology

Background:
- Targeting nanoparticles to tumors aims to improve cancer therapy efficacy and reduce side effects.
- The enhanced permeability and retention (EPR) effect is a primary rationale for nanoformulations but shows limitations in uniform tumor delivery.
- Current nanoformulations often result in modest increases in overall survival.
Purpose of the Study:
- To review the mechanisms and influencing factors of nanoparticle delivery in cancer therapeutics.
- To summarize current strategies for fabricating advanced, smart drug delivery systems for cancer treatment.
Main Methods:
- Literature review of nanoparticle delivery mechanisms in cancer.
- Analysis of factors influencing nanoparticle biodistribution and tumor penetration.
- Summary of fabrication strategies for smart nanomedicine.
Main Results:
- The enhanced permeability and retention (EPR) effect does not guarantee sufficient nanoparticle accumulation in all tumor regions.
- Variability in nanoparticle delivery exists across different patients and tumor types.
- Numerous factors, including nanoparticle properties and biological barriers, impact delivery efficiency.
Conclusions:
- Achieving uniform and effective nanoparticle delivery to tumors remains a significant challenge in nanomedicine.
- Further research into optimizing nanoparticle design and understanding influencing factors is necessary.
- Development of smart drug delivery systems is key to overcoming current limitations and realizing the potential of nanomedicine in cancer therapy.
