Objectives: Accurate target definition, treatment planning and delivery increases local tumor control for radiotherapy by minimizing collateral damage. To achieve this goal uveal melanoma (UM), tantalum fiducial markers (TFMs) were previously introduced in proton photon beam radiotherapy. However, TFMs cause pronounced scattering effects imaging that make the delineation of small tumors difficult. The aim study was to evaluate silicone (SFMs) guiding stereotactic radiosurgery (SRS) UM....

Abstract Purpose Patients with localized prostate cancer have various treatment options. Decision regret from a patient’s view is an unpleasant feeling concerning decision in health care. We aimed to explore and its determinants after external beam radiotherapy (EBRT) high dose-rate brachytherapy (HDR-BT) boost as traditional method of intensification. Methods conducted secondary analysis cross-sectional study. were enrolled at least two years EBRT + HDR-BT. was measured using the Regret...

One of the main goals in software solutions for treatment planning is to automatize delineation organs at risk (OARs). In this pilot feasibility study a clinical validation was made computed tomography (CT)-based extracranial auto-segmentation (AS) using Brainlab Anatomical Mapping tool (AM).The nine OARs (lungs, kidneys, trachea, heart, liver, spinal cord, esophagus) from datasets 24 treated patients retrospectively evaluated. Manual conducted routine and compared with AS AM. The Dice...

Abstract Purpose For patients with large tumors palliative radiotherapy often is the only local treatment option. To prevent toxicity administered doses are low. Dose escalation to tumor could be an option better smyptom control and prolong rates. In this prospective study we used a very pragmatic approach simultaneously integrated boost (SIB) almost geometrically defined core achieve this. The primary endpoint was demonstrate feasibility. Method Patients solid > 4 cm in diameter of...
