Gil Lederman discusses the Radiosurgery brain
A primary difference between the standard radiation and the radiosurgery stereotactic split is that the standard radiation must – because of less precision – radiate great numbers of normal healthy brain – compared with the radiosurgery, which concentrates on the tumour. The radiation of the healthy brain usually cannot be interpreted as always optimal and can, in fact, to lead to the complications. Radiosurgery represents the extreme reverse of the spectrum of the standard radiation – directed radiation focused with the prescribed amounts 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?
Radiation oncologists believe that higher doses of radiation are more beneficial in curing cancer, in general, than lower doses. However, higher doses cannot be given innocuously. Essentially, all tumors are surrounded by normal tissue. It is the presence of the normal tissue that limits the amount of radiation that can be safely administered. It’s our physicians’ large experience that helps to know when to increase or decrease doses! For benign conditions – such as acoustic neuromas – we are famous for using the lowest biologic effective dose in order to effectively treat the tumor and minimize harm to the surrounding fifth, seventh, eighth cranial nerves and brain stem. It’s for the patients’ benefit.
