Long term outcomes of stereotactic conformal radiation therapy in the treatment of benign and low-grade brain tumors

Health care assessments incorporating high end technology in cancer such as robotic surgery, intraoperative magnetic resonance imaging (MRI), particle beam therapy, high throughput molecular diagnostic etc. are challenging (1). In the field of radiation oncology, high-precision conformal techniques such as stereotactic radiosurgery/radiotherapy (RT), intensity modulated radiotherapy (IMRT) and particle therapy, etc., have been incorporated into routine clinical practice including for brain tumors based on dosimetric superiority and single arm studies without always being supported by randomized data.
