The use of dianhydrogalactitol provides a novel therapeutic modality for the treatment of glioblastoma multiforme and medulloblastoma. Dianhydrogalactitol acts as an alkylating agent on DNA that creates N7 methylation. Dianhydrogalactitol is effective in suppressing the growth of cancer stem cells and is active against tumors that are refractory to temozolomide; the drug acts independently of the MGMT repair mechanism.

The present invention relates to a production method for an anhydro sugar alcohol having a markedly reduced ion content and improved colour characteristics, and, more specifically, relates to a method for producing an anhydrous sugar alcohol having a markedly reduced ion content, markedly lowered electrical conductivity and improved colour characteristics, which is obtained by subjecting hydrogenated sugar (sugar alcohol) to a dehydration reaction and thereby converting same to an anhydrous sugar alcohol and then subjecting distilled water, which has been isolated through a distillation step, to a decolourizing process using activated carbon, and subsequently bringing the resulting decolourized substance into contact with an ion exchange resin.
