Background:

Nanoparticle delivery to tumors faces challenges from vascular permeability and poor diffusion within the tumor.
Effective tumor targeting is crucial for maximizing therapeutic efficacy and diagnostic accuracy of nanomedicines.

Purpose of the Study:

To explore how manipulating tumor physiology with antiangiogenic therapy can improve nanoparticle penetration.
To discuss the potential and challenges of combining antiangiogenic therapy with nanomedicines for cancer treatment and diagnosis.

Main Methods:

Investigated the effect of antiangiogenic therapy on tumor physiology.
Evaluated the penetration of 20 and 40 nm quantum dots into tumors under antiangiogenic treatment.
Reviewed preclinical and clinical data on combined antiangiogenic and nanomedicine approaches.

Main Results:

Antiangiogenic therapy was shown to improve the intratumoral diffusion of quantum dots.
Tumor physiology modification is a viable strategy to enhance nanoparticle delivery.

Conclusions:

Combining antiangiogenic therapy with nanomedicines offers a promising strategy to overcome delivery barriers in tumors.
Further preclinical and clinical studies are warranted to optimize this combination approach for cancer nanotherapeutics and imaging agents.
