Patient Selection Criteria Coverage for the use of stereotactic radiosurgery (SRS) using a gamma or linear-accelerator (LINAC) will be considered when any of the following criteria are met:  Arteriovenous malformations;  Acoustic neuromas;  Pituitary adenomas;  Non-resectable, residual or recurrent meningiomas;  Craniopharyngiomas;  Glomus jugulare tumors;  Solitary or multiple brain met...

BACKGROUND Oligometastases can be divided into sync-oligometastases and oligo-recurrence. The difference is whether the primary site is uncontrolled or controlled. The goal of this multicenter study was to evaluate treatment outcomes and factors affecting survival after stereotactic body radiotherapy for pulmonary oligometastases. METHODS The information after stereotactic body radiotherapy f...

BACKGROUND Limited data describe the prognosis after stereotactic ablative radiotherapy for lung metastases arising from colorectal cancer. Thus, we evaluated treatment outcomes of stereotactic ablative radiotherapy for those patients. METHODS The study involved patients received stereotactic ablative radiotherapy for one to three lung metastases arising from colorectal cancer at a single ins...

Background: Brain necrosis (RN) is a common radiotherapy sequela for brain metastases. Bevacizumab identified as therapeutic strategy RN. This study aimed to the clinical and radiobiological impacts on efficacy of in treating RN following stereotactic radiosurgery (SRS)

Stereotactic radiosurgery (SRS) and fractionated stereotactic radiotherapy (SRT) have been recognized as an alternative to surgery for small to medium sized vestibular schwannoma (VS). This study analysed and compared the outcomes of VS treated with the first Thailand installation of a dedicated Linac-based stereotactic radiation machine using single-fraction radiosurgery (SRS), hypofraction st...

INTRODUCTION Involvement of the central nervous system (CNS) secondary to colorectal cancer is infrequent and associated with a poor prognosis. Its treatment is extrapolated from metastases of other origins as the information available on this scenario is limited. The goal of this study is to assess the clinical characteristics of a series of patients and determine the results in terms of progr...

Patients with residual or recurrent Cushing's disease receive external beam radiotherapy (RT) with the aim of achieving long-term tumour control and normalization of elevated hormone levels. Treatment is given either as conventional radiotherapy using conformal techniques or as stereotactic radiotherapy, which is either used as fractionated treatment (SCRT) or as single fraction radiosurgery (S...

Surgery is the standard of care for patients with renal-cell carcinoma (RCC). Radiotherapy (RT) can decrease the risk of local recurrence after surgery and can lead to excellent outcomes in patients unfit for surgery. We reviewed clinical experience with various forms of RT, including conventional fractionated RT and intraoperative radiotherapy (IORT) as adjunct to surgery, hypofractionated hig...

BACKGROUND Painful spinal metastases have been treated with conventional radiotherapy for decades, but one-third of the patients have insufficient pain relief after treatment and one-fifth need retreatment. Stereotactic radiotherapy is a method to increase the dose in the spinal metastases with a potentially longer lasting palliative effect without increasing the side effects of the treatment a...
