External beam radiotherapy can be used to treat cutaneous squamous cell carcinomas (SCC). Acute skin toxicity is the most common adverse event. In this case study we report on an elderly patient with nasal root cutaneous SCC treated with stereotactic technique using a dedicated linear accelerator (CyberKnife system). Grade 3 skin toxicity was observed but it was resolved after 6 weeks. The use ...

In the 1950”s, Professor Lars Leksell of the Karolinska Institute in Sweden coined the term “radiosurgery” to define a neurosurgical procedure that combined precision targeting with a large number of cross-fired beams of ionizing radiation. By directing a very large dose of highly collimated radiation at a discrete location in the brain, the objective of Leksell’s operation was to make a lesion...

1 of 2 DESCRIPTION Intracardiac tumours move both with breathing and with the cardiac cycle; they therefore pose unique problems for radiotherapy delivery. Conventional radiotherapy must encompass the tumour with a margin to account for this motion, and the prescription is limited by myocardial radiation tolerance. The greater accuracy of radiosurgery allows higher radiation-dose deposition, wi...

The aim of reporting this case of choroid melanoma of the left eye is to introduce the in-house-designed treatment planning protocol for fractionated radiosurgical ablation of an intraocular lesion. This is a clinical case with emphasis on treatment preparation and delivery using the Accuray CyberKnife Robotic Radiosurgery System (Accuray, Sunnyvale, CA, USA) for a patient immobilized with a he...
