Stereotactic ablative body radiotherapy for lung cancer.
Lung stereotactic ablative radiotherapy (SABR) is a method of delivering high 'ablative' doses of radiotherapy to tumours in the lung. It was developed at the Karolinska Institute in the early 1990s using the methods established in cranial radiosurgery with multiple beams prescribed to an isodose and using a custom designed stereotactic body frame for immobilisation. Since then, aligned with th...
متن کاملStereotactic ablative radiotherapy for lung cancer
Stereotactic ablative radiotherapy (SABR), which is also referred to as stereotactic body radiotherapy (SBRT), is defined as “the precise irradiation of an image defined extra-cranial lesion associated with the use of high radiation dose in a small number of fractions”. SABR is a relatively recent advance in the treatment of small peripheral non-small cell lung tumours. The concept of SABR was ...
متن کاملOrganizing pneumonia after stereotactic ablative radiotherapy of the lung
BACKGROUND Organizing pneumonia (OP), so called bronchiolitis obliterans organizing pneumonia after postoperative irradiation for breast cancer has been often reported. There is little information about OP after other radiation modalities. This cohort study investigated the clinical features and risk factors of OP after stereotactic ablative radiotherapy of the lung (SABR). METHODS Patients u...
متن کاملQuantification of interplay and gradient effects for lung stereotactic ablative radiotherapy (SABR) treatments
This study quantified the interplay and gradient effects on GTV dose coverage for 3D CRT, dMLC IMRT, and VMAT SABR treatments for target amplitudes of 5-30 mm using 3DVH v3.1 software incorporating 4D Respiratory MotionSim (4D RMS) module. For clinically relevant motion periods (5 s), the interplay effect was small, with deviations in the minimum dose covering the target volume (D99%) of less t...
متن کاملNon-surgical treatment of lung cancer: personalised stereotactic ablative radiotherapy.
Stereotactic ablative radiotherapy has emerged as a standard treatment for medically inoperable stage I non-small-cell lung cancer and selected cases of lung metastasis. Techniques to freeze or limit tumour movement during treatment and image-guided radiation delivery are integral to a successful stereotactic ablative treatment without overdose of surrounding normal structures. In this article,...
