Summary:

      RATIONALE: Current therapies for adult recurrent/progressive oligodendrogliomas provide very
      limited benefit to the patient. The anti-cancer properties of Antineoplaston therapy suggest
      that it may prove beneficial in the treatment of childhood brain tumors.

      PURPOSE: This study is being performed to determine the effects (good and bad) that
      Antineoplaston therapy has on adult recurrent/progressive oligodendrogliomas.
