Synergy of Radiation and Immunotherapy
- Combining radiation therapy and immunotherapy may enhance anti-tumor responses in bladder cancer.
- Radiation releases tumor antigens and immunotherapy blocks tumor immune evasion pathways to boost immunity.
Clinical Trial Outcomes and Risks
- Clinical trials show combining radiation with immunotherapy can achieve high response rates in bladder cancer.
- However, toxicities vary and some combinations cause serious adverse events, requiring careful treatment planning.
Mechanism of Combined Treatment
- Radiation modifies the tumor environment to increase immune cell activity and immunotherapy reactivates T cells to fight tumors.
- This can induce systemic anti-cancer effects beyond the radiation site, known as the abscopal effect.
