Dosimetric effects of rotational offsets in stereotactic body radiation therapy (SBRT) for lung cancer.
To quantitatively evaluate dosimetric effects of rotational offsets in stereotactic body radiation therapy (SBRT) for lung cancer. Overall, 11 lung SBRT patients (8 female and 3 male; mean age: 75.0 years) with medially located tumors were included. Treatment plans with simulated rotational offsets of 1°, 3°, and 5° in roll, yaw, and pitch were generated and compared with the original plans. Bo...
متن کاملStereotactic Body Radiation Therapy (SBRT) for Unresectable Pancreatic Carcinoma
Survival in patients with unresectable pancreatic carcinoma is poor. Studies by Mayo Clinic and the Gastrointestinal Tumor Study Group (GITSG) have established combined modality treatment with chemotherapy and radiation as the standard of care. Use of gemcitabine-based chemotherapy alone has also been shown to provide a benefit, but 5‑year overall survival still remains less than 5%. Convention...
متن کاملStereotactic body radiation therapy (SBRT) for lung cancer
Stereotactic body radiation therapy (SBRT) has evolved over the past 15 years and revolutionized the management of early stage non-small cell lung cancer (NSCLC). Compared to conventional radiation therapy, SBRT offers superior outcomes, lower costs and greater patient convenience.1 SBRT likewise offers local control and cancer outcomes approaching surgical resection2-8 with lower risk of treat...
متن کاملAdaptive Stereotactic-body Radiation Therapy (SBRT) Planning for Lung Cancer Significance and Innovation: Tumor shrinkage during SBRT of lung cancer
Introduction: SBRT is an emerging radiotherapy technique for treating early-stage non-small cell lung cancers (NSCLC) or oligometastatic lesions to the lung [3, 4]. Significant tumor shrinkage has been observed in some patients during the course of SBRT [1, 2]. Adaptive planning has the potential to reduce radiation dose to organs of risk (OARs), and further escalate radiation dose to the tumor...
متن کامل[Availability of using diaphragm matching in stereotactic body radiotherapy (SBRT) at the time in breath-holding SBRT for liver cancer].
PURPOSE Liver image guided radiation therapy (IGRT) based on bone matching risks generating serious target positioning errors for reasons of lack of reproducibility of expiration breath hold. We therefore investigated the feasibility of 3D image matching between planning CT images and pretreatment cone-beam computed tomography (CBCT) images based on diaphragm surface matching. METHOD 27 liver...
