Abstract: | Bortezomib, doxorubicin and dexamethasone (PAD) was evaluated as induction before stem cell transplantation in newly diagnosed multiple myeloma (MM) patients, using bortezomib 1.3 mg/m(2) (PAD1, N = 21) or 1.0 mg/m(2) (PAD2, N = 20). Complete/very good partial response rates with PAD1/PAD2 were 62%/42% postinduction and 81%/53% post-transplant. Progression-free survival (29 vs. 24 months), time to re-treatment (36 vs. 29 months) and overall survival (1 year: 100% vs. 95%; 2 years: 95% vs. 73%) were statistically similar but favoured PAD1 versus PAD2. Toxicity was lower in PAD2; bortezomib dose reduction may help manage toxicities while retaining efficacy. PAD is highly active as front-line induction in MM. |
