CyberKnife - przyszłość w leczeniu raka stercza?

The aim of the study is an illustrative representation of the direction of the prostate cancer External Beam Radiotherapy evolution; mainly: the hypofractionated radiation therapy and radiosurgery. Our article describes the most important technological achievements allowing safe application of higher daily doses of radiation and reports potential advantages of hypofractionated over conventional external beam radiation therapy. It also considers some innovative solutions adopted in CyberKnife: and clinical significance of the potential reduction of geometric uncertainties in target volumes localization, enabled with the online tracking and treatment adaptation systems.
