I was diagnosed with Squamous cell throat cancer that has moved to the r/l limp nodes 1/17/08. No primary found to date. Am finishing with chemo and need to understand radiation options. We have a very good local treatment center here ( Hutchinson KS ), the Chalmers Cancer Treatment Center. They have the Varian 2100Ex system with IMRT. However they mentioned that in the next 3 months they would have the TomoTherapy HI-Art system available. Through my research this seems to be a great system for certain kinds of treatment to small areas, where protection of surrounding tissue is vital. Due to cost, there are not many of the systems around yet. Cancer Treatment Centrs of America have them at all their locations. Due to insurance issues we would be force to their Chicago ( Zion ) Il. location, which is a long way to travel. I have found that the Deaconess hosptal in Oklahoma City, about 3hrs. away the has one in use. Has any one heard of the advantages of the TomoTherapy Hi-Art systems.
