Insights

Strategies to remodel the tumor microenvironment (TME) can overcome biological barriers, improving nanodrug delivery for solid tumors. This review explores advanced TME remodeling approaches for enhanced cancer nanomedicine.

Area of Science:

  • Biomedical Engineering
  • Nanotechnology
  • Oncology

Background:

  • Nanodelivery systems offer promise for cancer therapy, but clinical success against solid tumors is limited.
  • In vivo barriers, including abnormal tumor vasculature, extracellular matrix (ECM), and stroma cells, hinder nanodrug penetration and distribution.
  • The tumor microenvironment (TME) presents significant obstacles to effective nanodrug delivery.

Purpose of the Study:

  • To review advanced strategies for TME remodeling to overcome biological barriers in nanodrug delivery.
  • To provide a guideline for implementing approaches that enhance intratumoral permeation of nanodrugs.
  • To analyze the pros and cons of TME remodeling methods and suggest future research directions.

Main Methods:

  • Literature review of TME remodeling strategies.
  • Analysis of biological barriers within the tumor microenvironment.
  • Evaluation of methods to alleviate these barriers for improved nanodrug delivery.

Main Results:

  • TME remodeling strategies can effectively mitigate barriers like abnormal vasculature, dense ECM, and stroma cells.
  • Targeted approaches can enhance nanodrug penetration and distribution within solid tumors.
  • Various remodeling techniques show potential for improving therapeutic outcomes.

Conclusions:

  • Overcoming TME-mediated biological barriers is crucial for advancing nanodrug delivery in solid tumors.
  • Strategic TME remodeling offers a promising avenue for enhancing cancer nanomedicine efficacy.
  • Further research into optimizing TME remodeling methods is warranted for clinical translation.
