AIMS AND BACKGROUND This retrospective analysis reports the outcomes obtained with an original once-weekly stereotactic radiotherapy fractionation given to patients affected by evolving oligometastases from different solid malignancies. METHODS From 2009 to 2011, patients with symptomatic and/or evolving oligometastases were submitted to a median 5-fraction cycle of stereotactic radiotherapy ...

We report our experiences of four cases with meningeal hemangiopericytoma treated with surgery and postoperative radiotherapy and survey the literature to elucidate the efficacy of radiotherapy. Patients were treated with surgical resection and 46-52 Gy postoperative radiotherapy. Three patients had local control for 30, 54 and 138 months, respectively and one patient had local recurrence after...

Gafchromic XRCT radiochromic film is a self-developing high sensitivity radiochromic film product which can be used for assessment of delivered radiation doses which could match applications such as computed tomography (CT) dosimetry. The film automatically changes color upon irradiation changing from amber to dark greenish-black depending on the level of exposure. The absorption spectra of Gaf...

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 ...

Introduction. Transarterial chemoembolization is the first-line treatment in unresectable hepatocellular carcinoma. There is no standard treatment after transarterial chemoembolization failure. We report the case of a patient with advanced hepatocellular carcinoma who showed a complete response and a long cancer control with hypofractionated stereotactic radiotherapy after transarterial chemoem...

Neovascular age-related macular degeneration is a leading cause of blindness in the developed world. Currently, the treatment of choice is intravitreal injections of anti-VEGF medications. These require frequent dosing, up to monthly, and impose a substantial burden on patients and the health economy. Ionizing radiation was proposed as a possible treatment for age-related macular degeneration d...
