Salvage fractionated Stereotactic Radiotherapy (fSRT) with or without chemotherapy and immunotherapy for recurrent Glioblastoma Multiforme: A single institution experience [PDF]

Frontiers in Oncology, 2015
Background: The current standard of care for salvage treatment of Glioblastoma Multiforme (GBM) is gross total resection and adjuvant chemoradiation for operable patients.

Comparing dosimetric performance of robust and planning target volume-based optimization in photon lung stereotactic radiotherapy. [PDF]

Med Phys
Abstract Background Stereotactic body radiation therapy (SBRT) is an effective treatment for lung tumors but it is challenged by respiratory motion and setup uncertainties. These are traditionally managed by optimizing on a planning target volume (PTV).

Comparative evaluation of normal tissue objective functions in robotic radiosurgery planning for solitary brain tumors. [PDF]

J Appl Clin Med Phys
Abstract Background The normal tissue objective (NTO) is an inverse planning approach in radiosurgery, also available for the CyberKnife system. By employing a model function, it aims to achieve precise control over the global dose fall‐off in healthy tissue.

Feasibility of treatment planning with HyperArc stereotactic radiosurgery methods for ocular tumors. [PDF]

J Appl Clin Med Phys
Abstract Purpose/objectives Currently, ocular disease is primarily managed with COMS plaque brachytherapy. Various stereotactic radiosurgery (SRS) platforms have also been employed, yet widespread access remains a challenge. Herein, we demonstrate the feasibility of using the HyperArc SRS system to provide an additional platform for the treatment of ...

Point Dosimetry in Patient-specific Quality Assurance of a Robotic Radiosurgery System Using a Scintillation Detector [PDF]

Journal of Medical Physics
Purpose: Patient-specific quality assurance (QA) for CyberKnife is typically performed using micro ionization chambers and film dosimetry. However, micro ionization chambers tend to underestimate dose measurements in small radiation fields.

Stratified dosimetric comparison between high-definition multileaf collimator-based D2SRS and robotic radiosurgery in the treatment of brain metastases. [PDF]

J Appl Clin Med Phys
Abstract Purpose To compare dosimetric characteristics and treatment efficiency between the high‐definition multileaf collimator (HD‐MLC) system and robotic radiosurgery (RRS) for brain metastases, with stratified analysis by lesion count. Methods Twenty‐nine patients (12 single [SBM], 17 multiple [MBM] brain metastases) treated with RRS (CyberKnife ...

Hypofractionated Stereotactic Radiotherapy with CyberKnife for Large Arteriovenous Malformations and Arteriovenous Malformations Located in Eloquent Areas

Neurologia Medico-Chirurgica, 2022
Literature has yet to establish an appropriate treatment strategy for large arteriovenous malformations (AVMs) and AVMs located in eloquent areas. In this study, the treatment outcomes of hypofractionated stereotactic radiotherapy (HSRT) with CyberKnife (
