Stereotactic Radiosurgery/Radiotherapy: A Historical Review [PDF]
Iranian Journal of Medical Physics, 2014 "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 ...

Is there a role for stereotactic radiotherapy in the treatment of renal cell carcinoma?
Clinical and Translational Radiation Oncology, 2019 Renal cell carcinoma (RCC) has traditionally been regarded as radioresistant tumor based on preclinical data and negative clinical trials using conventional fractionated radiotherapy. However, there is emerging evidence that radiotherapy delivered in few

Stereotactic multiple arc radiotherapy
The British Journal of Radiology, 1990 Abstract A radiotherapy technique is presented for delivering a concentrated pattern of absorbed dose to intracranial lesions. Treatment takes place on a conventional, isocentrically mounted linear accelerator, rotated in several planes around a single target site.

Stereotactic Body Radiotherapy
, 2017 Stereotactic body radiation therapy (SBRT) consists of the delivery of precise, conformal, hypofractionated, and ablative therapy in a single or a small number of fractions to extracranial regions. Over the last decade, it is rapidly being integrated into mainstream radiation oncology practices.

Stereotactic radiotherapy for bone oligometastases
Reports of Practical Oncology and Radiotherapy, 2022 About 60-90% of cancer patients are estimated to develop bone metastases, particularly in the spine. Bone scintigraphy, computed tomography (CT ) and magnetic resonance imaging (MRI ) are currently used to assess metastatic bone disease; positron emission tomography/computed tomography (PET-CT ) has become more widespread in clinical practice because ...

Stereotactic Body Radiotherapy
RADIOISOTOPES, 2012 定位放射線治療は，「小腫瘍に対して高精度に短期で3次元的に集中的大線量を投与する」と定義され，「切らずに治す」ことが可能となった。体幹部定位照射は，(1)1990年代半ばから急速に発展した照射装置の進歩，(2)固定精度の向上，(3)画像誘導技術，(4)呼吸性移動対策などによって，周囲臓器への危険を回避しながら腫瘍への投与線量を上げることが可能になり実現した。定位放射線治療は頭蓋内では約40年の歴史があるが，体幹部病変は固定法・呼吸性移動・線量計算の問題点によりまだ15年程度の経験しかない。それにもかかわらず，小型の肺癌・肺転移・肝腫瘍を中心に安全性と有効性について定位放射線治療の多くの臨床経験が積まれつつあり，特にもっとも治療経験が蓄積されているI期肺癌では ...

Stereotactic radiotherapy for intrahepatic cholangiocarcinoma
World Journal of Gastrointestinal Oncology, 2022 Intrahepatic cholangiocarcinoma (iCCA) is an aggressive malignancy with an increasing incidence worldwide and poor prognosis, despite several advances and continuous efforts to develop effective treatments. Complete surgical resection is the mainstay of treatment and offers a potentially curative option, but is only possible in less than a third of ...
