Stereotactic Radiosurgery for Sarcoma
نویسندگان
چکیده
The primary treatment of most sarcoma patients is surgery. The wider the excision, the lower the probability of local failure. For typical cases of non-CNS disease, adjuvant RT is offered in most cases in addition to surgery to optimize local control. However, bone and soft tissue sarcoma is historically considered a “radioresistant” tumor because conventionally fractionated radiation treatments have not been shown to be effective as primary treatment for this disease.

Development of A Head Docking Device for Linac-based Stereotactic Radiosurgery System to be Installed on Neptun 10 PC Linac
Introduction: Stereotactic radiosurgery is a technique for the treatment of intracranial lesions with highly collimated x-ray beam. Linac-based radiosurgery is currently performed by two techniques: couch or pedestal mounted. In the first technique, a device is required to affix patient's head to a couch and moreover to translate it accurately. Structure of suc...
متن کاملPulmonary metastasis from renal synovial sarcoma treated by stereotactic body radiotherapy: a case report and review of the literature.
Primary synovial sarcoma of kidney is an uncommon neoplasm, metastasizing most commonly to lung. Surgery and/or palliative chemotherapy for pulmonary metastases is commonly used to improve tumor control and survival. Stereotactic body radiotherapy (SBRT) is a relatively new approach to treat pulmonary metastasis, encouraged by the results of cranial and spinal stereotactic radiosurgery. The loc...
متن کاملStereotactic Radiosurgery/Radiotherapy: A Historical Review
"Stereotactic" is an exact radiotherapy treatment modality which implements invasive and non-invasive facilities for improving precise dose delivery. Stereotactic refers to three-dimensional localization of a specific point in space by a unique set of coordinates that relate to a fixed external reference frame. An accurate delivery of radiation is attainable using these techniques with high pre...
متن کاملDevelopment of a prototype stereotactic collimation assembly for Neptun 10 PC linac
Background: A set of hardware stereotactic radiosurgery is designed and constructed. The scope of this article is to describe how we have designed and developed stereotactic collimation assembly for a 9 MV Neptun 10 PC linac. Materials and methods: One collimator holder and six collimators were made, with their radiation field diameter between 12.5 mm to 25 mm at isocenter level. Beam data, suc...
متن کاملMeasurement of stereotactic beam data of 9 MV X-rays using diode detector
Background: Radiosurgery is a focal brain irradiation technique that delivers, usually in a single session, high dose of ionizing radiation. The presence of lateral electronic disequilibrium and steep dose gradients in small fields demands special attention to the selection of a suitable detector with respect to its size, composition and response. Materials and Methods : Small circular fields w...
