Filter by:In 2017 a novel treatment approach to a series of 5 patients with refractory VT was introduced, using ablative radiation with a stereotactic body radiation therapy (SBRT) technique to arrhythmogenic scar regions defined by noninvasive cardiac mapping. More recently, Robinson et al. reported on the results of their Electrophysiology-Guided Noninvasive Cardiac Radioablation for Ventricular Tachycardia (ENCORE-VT) trial, also using a similar SBRT technique in a series of 17 patients with refractory VT. Both studies report a marked reduction in VT burden, a decrease in antiarrhythmic drug use, and an improvement in quality of life. Since then, numerous other centres have detailed their initial experience with this technique. These initial results suggest that this new treatment paradigm has the potential to improve morbidity and mortality for patients suffering from treatment-refractory VT by means of a minimally invasive technique, but requires further validation for widespread use. The appropriate dose for therapeutic effect of this new treatment is not well established as only a single dose prescription of 25 Gy in 1 fraction has been described with benefit. In this phase 2 trial, the investigators plan on expanding the experience with this technique but also by contributing to understanding the relationship between dose-effect relationship through a dose de-escalation stratification, to 20 Gy in 1 fraction, with the goal of minimizing possible adverse events and radiation dose to surrounding healthy tissue while maintaining a clinical benefit.
This observational cohort will evaluate the cardiovascular effects of chemoradiation used to treat locally advanced, non-small cell lung cancer. Patients will be enrolled prior to the start of therapy and followed during and for at least 2 years after therapy with echocardiograms, nuclear stress tests, blood sampling, and quality of life surveys.
the main purpose of the present study was threefold: (1) to describe the thermographic response after radiation; (2) to investigate whether there was a significant temperature change over time and among the different radiation-dermatitis score; and (3) to test if temperature change could be used to predict the development of radiation-induced skin injury in the incipient stage.
