  salvage chemotherapy

     relapse or CNS 3 disease are not eligible. (Refer to Section 12.4 for definitions of
     CNS status)

     corticosteroid administration. The following uses of corticosteroids are permitted:
     single doses (e.g., during anesthesia), topical applications (e.g., for rash), inhaled
