Current approaches to improving immune checkpoint blockers for cancer treatment

Updated

Abstract

(ICIs) have transformed treatment outcomes for various malignancies.

  • Resistance to immune checkpoint blockade (ICB) presents a significant clinical challenge, with inconsistent response rates and temporary benefits.
  • Research into tumor characteristics is enhancing understanding of the mechanisms that contribute to ICI resistance.
  • The identification of predictive biomarkers may improve patient selection and treatment efficacy for ICBs.
  • Combination strategies are being explored to potentially overcome resistance to ICIs and increase treatment effectiveness.
  • Understanding the tumor immune microenvironment (TIME) is critical for developing personalized strategies to sensitize tumors to ICIs.
