Respiratory Gating during Stereotactic Body Radiotherapy for Lung Cancer Reduces Tumor Position Variability
PURPOSE We evaluated the effects of respiratory gating on treatment accuracy in lung cancer patients undergoing lung stereotactic body radiotherapy by using electronic portal imaging device (EPID) images. MATERIALS AND METHODS Our study population consisted of 30 lung cancer patients treated with stereotactic body radiotherapy (48 Gy/4 fractions/4 to 9 days). Of these, 14 were treated with- (...
متن کاملInterfractional Variations of Tumor Centroid Position and Tumor Regression during Stereotactic Body Radiotherapy for Lung Tumor
PURPOSE To determine interfractional changes of lung tumor centroid position and tumor regression during stereotactic body radiation therapy (SBRT). METHODS AND MATERIALS 34 patients were treated by SBRT in 4-5 fractions to a median dose of 50 Gy. The CT scans acquired for verification were registered with simulation CT scans. The gross target volume (GTV) was contoured on all verification CT...
متن کاملStereotactic 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 کاملComplications from Stereotactic Body Radiotherapy for Lung Cancer
Stereotactic body radiotherapy (SBRT) has become a standard treatment option for early stage, node negative non-small cell lung cancer (NSCLC) in patients who are either medically inoperable or refuse surgical resection. SBRT has high local control rates and a favorable toxicity profile relative to other surgical and non-surgical approaches. Given the excellent tumor control rates and increasin...
متن کاملStereotactic Body Radiotherapy for Early Stage Lung Cancer
Stereotactic body radiation therapy (SBRT) is a newly developed technique currently in clinical use. SBRT originated from stereotactic radiosurgery for intracranial tumors. SBRT has been widely used clinically for lung cancer. The practice of SBRT demands different kinds of patient fixation, breathing control, target determination, treatment planning, and verifications. The history and current ...
