My daughter, Chelsea, is halfway through her treatments (28 total) with Novalis. She had a 6cm tumor that was partially removed-75-80% -during 31 hours of a 2 part surgery. The portion that was left was on the brain stem an the neurosurgeons felt it too risky to take anymore. I have complete faith and trust in her neurosurgeon, Dr. Becker of UCLA. He explained why certain types of radiation works on different types of tumors and he felt that Novalis was the best choice for her. This is from the UCLA Neurosurgery site on the web:
Novalis Shaped Beam Radiosurgery versus Gamma KnifeThe inception of the UCLA Stereotactic Radiosurgery Program began 25 years ago when the Karolinska Institute of Stockholm, Sweden, donated one of two "gamma knife" units in existence at the time for the purpose of collaborative research. Since that time the UCLA Radiosurgery Team has worked with the Gamma Knife, LINAC Scalpel, XKnife and more recently, with the Novalis Shaped Beam Surgery. The Novalis Shaped Beam Surgery is most advanced development in radiosurgery to date. UCLA is the only center in the United States to use a dedicated Varian SR600 Shaped Beam Surgery, stereotactic radiosurgery and stereotactic radiotherapy system. Unlike the Gamma Knife, which is limited to delivering single-dose treatments, the Novalis delivers narrow, well-defined beams that conform to the lesion(s) for both single and multiple dose treatments. Clinical results have demonstrated that delivering multiple or "fractionated doses" provides a therapeutic advantage for treating tumors that abut or include cranial nerves or critical regions of the brain. Furthermore, research studies estimate that about one-half of all radiosurgery treatments would be better treated with multiple small doses. Based on these technological advancements coupled with proven clinical results, the Novalis is now considered the "Gold Standard" for shaped-beam radiosurgery.
I know that we all have to do our research and trust the doctors and our decisions throughout this journey.
