A novel CBCT-based method for derivation of CTV-PTV margins for prostate and pelvic lymph nodes treated with stereotactic ablative radiotherapy
BACKGROUND Traditional CTV-PTV margin recipes are not generally applicable in the situation of stereotactic ablative radiotherapy (SABR) treatments of multiple target volumes with a single isocentre. In this work, we present a novel geometric method of margin derivation based on CBCT-derived anatomical data. METHODS Twenty patients with high-risk localized prostate cancer were selected for re...
متن کاملIGRT versus non-IGRT for postoperative head-and-neck IMRT patients: dosimetric consequences arising from a PTV margin reduction
BACKGROUND To evaluate the impact of image-guided radiation therapy (IGRT) versus non-image-guided radiation therapy (non-IGRT) on the dose to the clinical target volume (CTV) and the cervical spinal cord during fractionated intensity-modulated radiation therapy (IMRT) for head-and-neck cancer (HNC) patients. MATERIAL AND METHODS For detailed investigation, 4 exemplary patients with daily con...
متن کاملImage-guided percutaneous targeting of lymph nodes: a novel approach for salvage pelvic lymphadenectomy in recurrent prostate cancer
Recently, Torricelli et al. (1) published a video showing a step by step technique for salvage lymph node dissection after radical prostatectomy. With the development of novel imaging techniques, the identification of PCa patients with a clinical lymphonode (LN) relapse has become feasible. Salvage LN dissection (SLND) represents a treatment option for patients with prostate cancer relapse limi...
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 کاملMR imaging of pelvic lymph nodes
The occurrence of metastases to pelvic lymph nodes profoundly affects the prognosis of pelvic malignancies, making accurate staging crucial for selecting appropriate treatment. Modalities for the detection of metastatic lymph nodes are lymph node dissection, lymphangiography, and non-invasive techniques such as computed tomography (CT) and magnetic resonance imaging (MRI); the role of these tec...
