This protocol combines several highly active chemotherapeutic agents in an attempt to improve upon response rates achieved with current combinations. For high-risk stage II and III patients, this chemotherapy regimen (without genetic manipulation of PBPCs) will serve as a chemotherapy backbone onto which a companion immunotherapy protocol will be offered. An identical chemotherapy regimen will be offered to stage four patients as a backbone for a trial of retroviral transduction of the MDR1 and NeoR genes into harvested PBPCs.
