The document discusses three clinical trials for treating acute childhood leukemia and multiple myeloma: 1) The "total therapy" trials at St. Jude significantly raised cure rates for childhood acute leukemia from less than 10% to over 95% by applying all active drugs upfront instead of reserving them for relapse. 2) The first myeloma tandem transplant trial enrolled 231 patients, and at 10 years 33% were still alive and 15% had never relapsed. 3) Total Therapy 2 built upon Total Therapy 1 for multiple myeloma by using more intensive induction therapy, consolidation chemotherapy after transplants, and adding dexamethasone pulsing and thalidomide during maintenance.
