Benefits of TomoTherapy(R) Radiation Therapy Highlighted in 82 Studies to Be Presented at ESTRO 29 in Barcelona

MADISON, WS, Sep 08, 2010 (MARKETWIRE via COMTEX) -- TomoTherapy Incorporated /quotes/comstock/15*!tomo/quotes/nls/tomo (TOMO 3.11, +0.02, +0.68%) , maker of advanced radiation therapy solutions for cancer care, today announced that 82 studies examining the use of the TomoTherapy(R) treatment system to treat common, complex and rare tumors throughout the body will be showcased at ESTRO 29, September 12-16, 2010, in Barcelona. The studies examine use of the TomoTherapy system on head and neck, prostate, breast and lung tumors, as well as for treating blood cancers, mesothelioma and pediatric patients.

In one of the most promising papers, researchers from San Raffaele Scientific Institute in Milan, Italy compared TomoTherapy to other radiation therapy solutions using Pareto front analysis to explore the ability of these treatment methods to improve target coverage without sacrificing organs at risk (OAR) or other constraints. Researchers reported that "for all simulations RapidArc(R) met less of the optimization criteria, while TomoTherapy was able to produce the most homogeneous dose and have the capability to conform dose distributions better than RapidArc(R)."

Head and Neck Cancers Among the numerous studies on head and neck tumors, two studies compare arc therapy to helical TomoTherapy radiation delivery. Exploring the treatment of patients with oropharyngeal cancer, researchers in Belgium and the Netherlands concluded that in the treatment of head and neck cancer, helical TomoTherapy treatment times are less than both Smart Arc and step and shoot techniques. In fact, TomoTherapy treatment was fastest of all techniques examined, at 6.6 minutes, compared to 7.5 minutes for Smart Arc and longer times for other intensity-modulated radiation therapy (IMRT) techniques, while delivering the best homogeneity and equivalent or better OAR sparing.
