The purpose of this study is to evaluate the effectiveness of low dose dexamethasone versus high dose dexamethasone in the treatment of radiation induced vomiting.
Dexamethasone is an effective medication to ameliorate radiation induced headache and vomiting. In our Toronto experience dexamethasone in low doses (1 mg/m2/day) is sufficient in treating these symptoms. However this experience is not shared from many neuro-oncology centers of excellence that more commonly use 5 mg/m2/day according to the results of the trans-Canadian survey. A prospective multicenter trial evaluating the effectiveness of dexamethasone in different dose regimens in symptomatic children while undergoing CNS radiation will elucidate the appropriate dose.

Mice selectively bred for hypersusceptibility to two-stage chemical skin carcinogenesis. They are also hypersusceptible to UV radiation tumorigenesis with single high-dose, but not chronic low-dose, exposures. SENCAR (SENsitive to CARcinogenesis) mice are used in research as an animal model for tumor production.
The highest dose of a biologically active agent given during a chronic study that will not reduce longevity from effects other than carcinogenicity. (from Lewis Dictionary of Toxicology, 1st ed)
The specific failure of a normally responsive individual to make an immune response to a known antigen. It results from previous contact with the antigen by an immunologically immature individual (fetus or neonate) or by an adult exposed to extreme high-dose or low-dose antigen, or by exposure to radiation, antimetabolites, antilymphocytic serum, etc.
