Witryna30 cze 2024 · Proton radiotherapy has a dosimetric advantage over photon radiotherapy. Many retrospective studies have shown promising results with proton radiotherapy in treating hepatocellular carcinoma (HCC). However, clinical evidence demonstrating the benefit of protons over photons is still limited. We therefore … Witryna9 lip 2013 · Radiation therapy uses high-energy x-rays, protons, and other types of radiation to kill tumor cells and shrink tumors. It is not yet known whether intensity-modulated proton beam therapy is more effective than intensity-modulated photon therapy in treating oropharyngeal cancer.
