Verification of beam delivery using fibrosis after proton beam irradiation to the lung tumor.
BACKGROUND AND PURPOSE To investigate the geometrical accuracy in proton beam therapy (PBT) to the lung by comparing the location of the fibrosis after PBT and the tumor using less invasive method. PATIENTS AND METHODS We examined 50 lung tumors that had been treated by respiratory-gated PBT (33-74 Gray equivalents). Image registration and re-slicing of computed tomography (CT) before and aft...
متن کاملProton beam irradiation inhibits the migration of melanoma cells
PURPOSE In recent years experimental data have indicated that low-energy proton beam radiation might induce a difference in cellular migration in comparison to photons. We therefore set out to compare the effect of proton beam irradiation and X-rays on the survival and long-term migratory properties of two cell lines: uveal melanoma Mel270 and skin melanoma BLM. MATERIALS AND METHODS Cells tr...
متن کاملIntraocular inflammation after proton beam irradiation for uveal melanoma.
AIM To describe the inflammatory reaction that can occur following proton beam irradiation of uveal melanomas based on a large series of patients and to try to determine the risk factors for this reaction. METHODS Data from a cohort of patients with uveal melanoma treated by proton beam irradiation between 1991 and 1994 were analysed. The presence of inflammation was recorded and evaluated. K...

متن کاملDesigned-seamless irradiation technique for extended whole mediastinal proton-beam irradiation for esophageal cancer
BACKGROUND Proton-beam therapy (PBT) provides therapeutic advantages over conformal x-ray therapy in sparing organs at risk when treating esophageal cancer because of the fundamental physical dose distribution of the proton-beam. However, cases with extended esophageal lesions are difficult to treat with conventional PBT with a single isocentric field, as the length of the planning target volum...
