Song and colleagues deliver athorough and fair review of theinitial clinical investigations ofa new paradigm in radiotherapy mostrecently called stereotactic body radiationtherapy (SBRT).[1] Oncology observers may take exception withthe use of the designation “new paradigm.”After all, from a tumor controlpoint of view, skeptics might say,“radiotherapy is radiotherapy.” Recentadvances in radiotherapeutictechnology such as three-dimensionsal(3D) conformal therapy and intensity-modulated radiotherapy (IMRT)have made treatments less toxic, butnot particularly more effective in curingcancer.
