Abstract
Standard-of-care for newly-diagnosed, autologous hematopoietic stem cell transplantation (auto-HCT)-eligible, multiple myeloma (MM) patients includes bortezomib, lenalidomide, and dexamethasone (VRD) induction followed by melphalan 200 mg/m(2) (Mel200)-conditioned auto-HCT and lenalidomide maintenance. We completed a retrospective case series assessing outcomes of 187 MM patients who received this regimen at our institution. The 100-day non-relapse mortality incidence was zero. Before auto-HCT, 9.6 and 52.9% of patients achieved a complete response (CR) or ≥ very good partial response (VGPR), respectively. At day-100 post-transplant, 29.4 and 74.9% had achieved a CR/stringent-CR (sCR) or ≥ VGPR, respectively. At the last evaluation, 57.2% of patients had CR/sCR and 87.1% had ≥ VGPR. Median follow-up, progression-free survival (PFS), and overall survival (OS) were 63.2, 50, and 101.7 months, respectively. The 5-year PFS and OS were 43.1 and 79%. High-risk cytogenetics was associated with worse outcomes. This study illustrates that VRD induction, Mel200-conditioned auto-HCT, and lenalidomide maintenance are associated with good outcomes in MM.

Abstract
High-dose rituximab (HD-R) combined with carmustine, cytarabine, etoposide and melphalan (BEAM) and autologous stem cell transplant (ASCT) was effective and tolerable in a single-arm prospective study of relapsed aggressive B-cell non-Hodgkin lymphoma (R-NHL). We performed a randomized phase 2 study comparing HD-R versus standard-dose rituximab (SD-R) in R-NHL. Ninety-three patients were randomized to HD-R (1000 mg/m2 ) (n = 42) or SD-R (375 mg/m2 ) (n = 51) administered on post-transplant days +1 and +8, using a Bayesian adaptive algorithm. The 2 treatment arms were balanced in regards to patient demographic and clinical characteristics. At a median follow-up of 7.92 years, the 5-year disease-free survival (DFS) and overall survival (OS) were 40% and 48%, respectively. We found no statistically significant differences between HD-R and SD-R in 5-year DFS (36% vs. 43%; P = 0.205) and OS (43% vs. 52%; P = 0.392). In multivariate analyses, only disease status before ASCT [residual disease versus complete remission (CR)] (hazard ratio [HR] 1.79, 95% confidence interval [CI]: 1.08-2.95) and number of prior treatments received (>2 vs. <=2 lines of treatment) (HR 1.89, 95% CI: 1.13-3.18) were associated with worse DFS and OS. Patients who had SCT while in CR or who received <=2 lines of treatment prior to SCT had better 5-year OS (57% vs. 35%; P = 0.02 and 54% vs. 30%, P = 0.001, respectively) in both arms. No differences in engraftments or adverse events were noted in the 2 arms. When combined with BEAM and ASCT in relapsed aggressive B-cell NHL, HD-R provided no DFS or OS advantage over SD-R. In patients who have been exposed to rituximab in the frontline or salvage setting, the addition of rituximab in the peri-transplant setting remains controversial.
