Image-guided stereotactic body radiation therapy (SBRT): an emerging treatment paradigm with a new promise in radiation oncology
Stereotactic radiosurgery (SRS), coupling radiation with a stereotactic guiding device, was first performed by Leksell in 1951 [1]. SRS is now an established treatment option for many benign and malignant tumours. With the advances in technology, including patient/target immobilisation, tumour/target tracking, image-guidance, and radiation planning and delivery, SRS to extracranial sites has be...
متن کاملEvaluation of initial setup errors of two immobilization devices for lung stereotactic body radiation therapy (SBRT)
The aim of this study was to investigate the accuracy and efficacy of two commonly used commercial immobilization systems for stereotactic body radiation therapy (SBRT) in lung cancer. This retrospective study assessed the efficacy and setup accuracy of two immobilization systems: the Elekta Body Frame (EBF) and the Civco Body Pro-Lok (CBP) in 80 patients evenly divided for each system. A cone ...
متن کاملImage-guided radiation therapy (IGRT) in gastrointestinal tumors.
CONTEXT Daily setup errors and changes in body habitus during external beam radiotherapy can result in interfraction variation, contributing to uncertainties in treatment delivery. The conventional method of patient positioning using external skin markings is inadequate in reducing these interfraction variations. OBJECTIVE To evaluate use of on-board imaging with daily kV-kV image matching to...
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...
