Purpose: Both local tumor control and distant metastasis are important indicators of the efficacy of radiation therapy treatment. Synchrotron microbeam radiation therapy (MRT), spatially fractionated radiation delivered at ultrahigh dose rates, shows remarkable normal tissue sparing with excellent local control in some models. Some MRT regimens trigger an antitumor immune response that contributes not only to the local but also to systemic treatment efficacy.

We show that Microbeam Radiotherapy (MRT), an innovative type of Spatially Fractionated Radiotherapy, can control murine melanoma by activating the host's own immune system. The beneficial effects are very pronounced in comparison to uniform radiotherapy traditionally employed in the clinic.
