Background And Purpose: In patients with recurrent ventricular tachycardia (VT), STereotactic Arrhythmia Radioablation (STAR) shows promising results. The STOPSTORM.eu consortium was established to investigate and harmonise STAR treatment in Europe.

- Deep learning models for auto-segmentation in radiotherapy were evaluated for their effectiveness in segmenting cancerous areas, focusing on both quantitative and qualitative measures.
- The study involved training separate models for left- and right-sided breast cancer, measuring the time taken for automatic and manual segmentation, and comparing them using several scoring techniques.
- Results showed significant time savings with auto-segmentation—averaging about 42% to 58% reduction in time—while maintaining high accuracy, as 92% of automatically generated contours were deemed clinically acceptable.
Article Synopsis
- * The trial included 84 patients and found that those receiving radiotherapy experienced significant pain reduction and improvements in quality of life and walking abilities at 12 and 18 months compared to those who received a placebo.
- * Most side effects reported were mild, with 87% resolving by the 18-month follow-up, reinforcing radiotherapy's effectiveness for this condition.
Background: Stereotactic radiosurgery (SRS) is a frequently chosen treatment for patients with brain metastases and the number of long-term survivors is increasing. Brain necrosis (e.g.
