Osama Mohamad, Zabi Wardak, Daniel C Bowers, Anh H Le, Tu Dan, Ramzi Abdulrahman, Lynn Gargan, Laura Klesse, Bradley Weprin, Dale Swift, Angela Price, Chuxiong Ding, Strahinja Stojadinovic, Frederick Sklar, Bruno Braga, Robert Timmerman,

BACKGROUND:Conventional radiotherapy (RT) to pediatric brain tumors exposes a large volume of normal brain to unwarranted radiation causing late toxicity. We hypothesized that in well demarcated pediatric tumors lacking microscopic extensions, fractionated stereotactic RT (SRT), without target volume expansions, can reduce high dose normal tissue irradiation without affecting local control. ...
