Gut microbiome may improve immune therapy for liver cancer

Abstract

The gut microbiome may significantly influence the effectiveness of immune checkpoint inhibitors in treating hepatocellular carcinoma (HCC).

  • Specific anti-tumor cells can be activated and strengthened by immune checkpoint inhibitors (ICIs), leading to sustained tumor response rates in many HCC patients.
  • Some patients with unresectable HCC do not experience long-term benefits from immunotherapy due to acquired resistance mechanisms.
  • There is significant variability in how individuals' gut microbiomes respond to treatment with ICIs.
  • Targeting specific gut microbes could enhance the effectiveness of checkpoint blockade therapies in HCC.
  • Manipulating the gut microbiome presents a clinical strategy that may improve response rates to cancer ICI therapy.
