Abstract
Cancer progression relies on evasion of the immune response. Immune checkpoint blockade (ICB) therapy restores this immune response for many cancer types by preventing the binding of immune checkpoints on the surface of immune cells to their ligands [1]. Resistance to ICB therapy is common, therefore monitoring the response to ICB treatment is essential for improving cancer treatment [2].
Researchers at McMaster University have discovered novel multigene and individual gene panels that can effectively predict response to ICB therapy [3].
Applications
- Clinical applications as a prognosis tool in assessing response to ICB treatment via individual genes and multigene panels.
- Potential targets for ICB therapy or other cancer therapies.
Advantages
- Outperformed well-established biomarkers of ICB response.
- Expression of individual genes correlate to multiple immune checkpoint expressions across 30 cancer types.
