Image guided dose escalated prostate radiotherapy: still room to improve
BACKGROUND Prostate radiotherapy (RT) dose escalation has been reported to result in improved biochemical control at the cost of greater late toxicity. We report on the application of 79.8 Gy in 42 fractions of prostate image guided RT (IGRT). The primary objective was to assess 5-year biochemical control and potential prognostic factors by the Phoenix definition. Secondary endpoints included a...
متن کاملCorrection: Image guided dose escalated prostate radiotherapy: still room to improve
We regret to report that a proofreading error caused an incorrect legend and description of the contents of table 6 to appear in our original publication of this work. The correct description of table 6 is: Univariate analysis of prognostic factors for 5-year nadir + 2 biochemical outcome for men presenting with intermediate risk factors. CorrectionWe regret to report that a proofreading er...
متن کاملImage-guided prostate radiotherapy: analysis of inter- fractional setup errors
Introduction: The accuracy of the patient setup and tumor location are major factors that determine the efficacy of radiotherapy treatment planning. In the prostate radiotherapy, reproducibility of the prostate location for each treatment fraction is problematic owing to varying filling of the rectum and bladder. According to this, the aim of this study was to measure the inte...
متن کاملDosimetric and Radiobiological Evaluation of Multiparametric MRI-guided Dose Painting in radiotherapy of Prostate Cancer
Introduction: Radiotherapy is one of the treatment options for locally advanced prostate cancer, however with standard radiation doses it is not always very effective. One of the strategies to improve the efficiency of radiotherapy is increasing the dose. In this study to increase tumor local control rates a new radiotherapy method, known as dose painting (DP) was investigated....
متن کاملImprovement in toxicity in high risk prostate cancer patients treated with image-guided intensity-modulated radiotherapy compared to 3D conformal radiotherapy without daily image guidance
BACKGROUND Image-guided radiotherapy (IGRT) facilitates the delivery of a very precise radiation dose. In this study we compare the toxicity and biochemical progression-free survival between patients treated with daily image-guided intensity-modulated radiotherapy (IG-IMRT) and 3D conformal radiotherapy (3DCRT) without daily image guidance for high risk prostate cancer (PCa). METHODS A total ...
