Combining radiation and immunotherapy: a new systemic therapy for solid tumors?

Area of Science:

• Oncology
• Immunology
• Radiation Oncology

Background:

• Checkpoint inhibitors and immunomodulating agents show recent success in cancer therapy.
• Combining these agents with radiation is a promising strategy.
• The goal is to leverage radiation-induced tumor antigen release to enhance immune response.

Purpose of the Study:

• To provide a comprehensive overview of the evidence for combining radiation with immunomodulating agents.
• To explore the potential of inducing the abscopal effect.

Main Methods:

• Review of early clinical evidence.
• Review of preclinical evidence.

Main Results:

• Early data suggests potential for immune-mediated tumor regression outside the radiation field.
• The combination strategy shows promise in preclinical and early clinical settings.

Conclusions:

• The combination of radiation and immunotherapy is a developing field with potential for significant clinical impact.
• Further research is warranted to optimize this approach and understand the abscopal effect.
