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

Respiration-Induced Intraorgan Deformation of the Liver: Implications for Treatment Planning in Patients Treated With Fiducial Tracking. [PDF]

, 2017
Stereotactic body radiation therapy is a well-tolerated modality for the treatment of primary and metastatic liver lesions, and fiducials are often used as surrogates for tumor tracking during treatment. We evaluated respiratory-induced liver deformation

Stereotactic Body Radiotherapy for Treatment of Squamous Cell Carcinoma of the Tongue Base Associated with Human Papilloma Virus

Frontiers in Oncology, 2013
Stereotactic body radiotherapy has emerged as a treatment for recurrent squamous cell carcinoma of the head and neck in the field of prior radiation. We report a case of its use in an HPV positive patient with squamous cell carcinoma of the right base ...

The role of stereotactic radiosurgery in the multimodal management of growth hormone–secreting pituitary adenomas [PDF]

, 2010
Growth hormone (GH)–secreting pituitary adenomas represent a common source of GH excess in patients with acromegaly. Whereas surgical extirpation of the culprit lesion is considered first-line treatment, as many as 19% of patients develop recurrent ...

Dosimetric validation of a magnetic resonance image gated radiotherapy system using a motion phantom and radiochromic film. [PDF]

, 2017
PurposeMagnetic resonance image (MRI) guided radiotherapy enables gating directly on the target position. We present an evaluation of an MRI-guided radiotherapy system's gating performance using an MRI-compatible respiratory motion phantom and ...

Application of a genetic signature of late GU toxicity in SCIMITAR, a Post-op SBRT trial

Clinical and Translational Radiation Oncology, 2023
Predictors of genitourinary toxicity after post-prostatectomy radiotherapy remain elusive. A previously defined germline DNA signature (PROSTOX) has shown predictive ability for late grade ≥ 2 GU toxicity after intact prostate stereotactic body ...

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 Body Radiotherapy – Current Indications

Klinicka Onkologie, 2019
Stereotactic body radiotherapy (SBRT) is used to treat localized tumor lesions and consists of applying high doses of radiation to a small number of fractions using specially equipped linear accelerators, modern immobilization devices, and imaging methods, which are considered special, advanced techniques in modern day radiotherapy. SBRT is a very well

Elimination of refractory ventricular tachycardia storm and fibrillation using stereotactic radiotherapy

Clinical Case Reports, 2023
Ventricular tachycardia storm is a potentially lethal condition with limited treatment options. Failed ablation is associated with a fourfold mortality increase in this population. Stereotactic body radiotherapy was proposed in these cases.
