A method includes generating a hyperthermia heat plan for tissue of interest, generating a hyperthermia adapted radiation therapy plan for the tissue of interest, controlling a heat source (126) to deliver heat to the tissue of interest according to the hyperthermia heat plan, and controlling a radiation source of a radiation therapy system (100) to deliver radiation to the tissue of interest according to the hyperthermia adapted radiation therapy plan. A system includes a radiation treatment planner (124) configured to generate a hyperthermia adapted radiation therapy plan for the tissue of interest, a radiation therapy system (100) configured to deliver radiation in accordance with the hyperthermia adapted radiation therapy plan, and a hyperthermia heat delivery system (126) configured to deliver heat in accordance with a hyperthermia plan.
