Gil Lederman Discusses Brain Radiosurgery Gil Lederman Discusses Brain Radiosurgery A primary difference between standard radiation and fractionated stereotactic radiosurgery is that standard radiation must - because of less precision - radiate large amounts of normal healthy brain - compared to radiosurgery, which focuses on the tumor. Radiation of healthy brain usually cannot be construed as always optimal and may, in fact, lead to complications. Radiosurgery represents the opposite end of the spectrum from standard radiation - focused directed radiation with prescribed doses of treatment. Think of a plum in a breadbox and imagine the plum is the tumor while the brain is the breadbox. Standard radiation treats the larger breadbox while we isolate the plum for treatment. That means we can escalate the dose to the tumor and diminish much of the unnecessary dose to normal brain tissue. That should mean less chance of late adverse effects. Stereotactic radiosurgery has a greater degree of accuracy than just conformal radiation. There are issues concerning risks, benefits and alternatives that must be discussed. While IMRT (Intensity Modulated Radiation Therapy) helps shape the radiation, it is only one part of our innovative program. How does Fractionation of Radiosurgery Help the Patient?
