In view of their superior soft tissue contrast compared to computed tomography, magnetic resonance images are commonly involved in stereotactic radiosurgery/radiotherapy applications for target delineation purposes. It is known, however, that magnetic resonance images are geometrically distorted, thus deteriorating dose delivery accuracy. The present work focuses on the assessment of geometric ...

Stereotactic ablative body radiotherapy (SABR) represents a technological breakthrough in radiotherapy technique, with proven benefits to patients in terms of improved tumour control and overall survival. The key components of SABR are described. The current evidence base for SABR for the treatment of primary and secondary lung tumours is appraised, and key ongoing trials are identified.

BACKGROUND Despite the advancement of microsurgical and endoscopic techniques, some nonfunctioning pituitary adenomas (NFPAs) can be difficult to cure. Tumor recurrence or incomplete resection may occur in some patients with NFPAs, and management strategies for these NFPAs remain unclear. OBJECTIVE To review the existing literature as it pertains to the management of postsurgical residual or ...

Abstract Objective Recently modern systemic therapy and stereotactic irradiation have been developed. We reviewed the therapeutic outcome of brain metastases (BM) in patients with melanoma. Methods Data melanoma BM were retrospectively analyzed. Patients underwent multidisciplinary treatment, whole radiotherapy, irradiation, immune check point inhibitor (ICI) and/or BRAF inhibitor, indication w...

BACKGROUND Radiotherapy plays a major role in the management of high grade glioma. However, the radioresistance of glioma cells limits its efficiency and drives recurrence inside the irradiated tumor volume leading to poor outcome for patients. Stereotactic hypofractionated radiotherapy is one option for recurrent high grade gliomas. Optimization of hypofractionated radiotherapy with new radios...

The objective of this study was to compare the effects of image-guided hypofractionated radiotherapy and conventional fractionated radiotherapy on non-small-cell lung cancer (NSCLC). Fifty stage- and age-matched cases with NSCLC were randomly divided into two groups (A and B). There were 23 cases in group A and 27 cases in group B. Image-guided radiotherapy (IGRT) and stereotactic radiotherapy ...
