Key points

  • PD-1/PD-L1 blockade is a significant advance in treating breast cancer.
  • This therapy shows impressive antitumor activity.
  • It may lead to durable long-term disease control, particularly in TNBC.
  • Immune-related adverse events (irAEs) are a potential side effect.

Abstract

Immune checkpoint inhibition represents a major recent breakthrough in the treatment of malignant diseases including breast cancer. Blocking the programmed death receptor-1 (PD-1) and its ligand, PD-L1, has shown impressive antitumor activity and may lead to durable long-term disease control, especially in the triple-negative subtypes of breast cancer (TNBC). Although immune checkpoint blockade is generally well tolerated, specific immune-related adverse events (irAEs) may occur. This review summarizes the clinical efficacy, perspectives, and future challenges of using PD-1/PD-L1-directed antibodies in the treatment of breast cancer.
