High Dose Chemotherapy not all that useful for patients with progressive disease…
High-Dose Chemotherapy With ABMTIs Effective in Relapsed Chemosensitive DLBCL: Parma
Study
• 215 patients treated with 2 cycles of DHAP • 109 patients showed CR or PR and were randomized to
– Conventional treatment: 4 more cycles of DHAP (n = 54)– High-dose treatment: BEAC (carmustine, etoposide, cytarabine,
cyclophosphamide, and mesna) + ABMT (n = 55)

Misconception….
• High dose chemotherapy is not effective in those with progressive disease (NEJM 1987)
• Limit studies to those with CR/PR to salvage (PARMA)
• It does not work in those excluded from PARMA study
• They should be offered investigational therapies (drugs or medical procedures that are under investigation in clinical trials regarding their safety and efficacy)
What are the Data?
Two studies…

Misconcep·tion
• Many with less than partial responses to salvage therapy will achieve durable remissions from high dose chemotherapy and autologous or allogeneic transplant.
• Delays in treatment from investigational treatments may adversely affect long-term outcome….
