- BACKGROUND: Allogeneic stem cell transplantation (alloSCT) reduces relapse rates in acute leukemia, but outcome is hampered by toxicity. Population-based data avoid patient selection and may therefore substitute for lack of randomized trials. METHODS: We evaluated alloSCT rates within the Swedish Acute Leukemia Registry, including 3899 adult patients diagnosed from 1997 through 2006 with a coverage of 98% and a median follow-up of 6.2 years. RESULTS: AlloSCT rates and survival decreased rapidly with age andgt;55 years. The 8-year overall survival (OS) was 65% in patients andlt;30 years and 38% in patients andlt;60 years and was similar for acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL). Among 1073 patients andlt;60 years, alloSCT was performed in 42% and 49% of patients with AML and ALL, respectively. Two-thirds of the alloSCTs were performed in first complete remission, and half used unrelated donors, the same in AML and ALL. Regional differences in management and outcome were found: 60% of AML patients andlt;40 years received alloSCT in all parts of Sweden, but two-thirds of AML patients 40-59 years had alloSCT in one region compared with one-third in other regions (Pandlt;.001), with improved 8-year OS among all AML patients in this age cohort (51% vs 30%; P = .005). CONCLUSIONS: More Swedish AML patients received alloSCT, and long-term survival was better than in recently published large international studies, despite our lack of selection bias. There was no correlation between alloSCT rate and survival in ALL. In adult AML patients andlt;60 years of age, a high alloSCT rate was associated with better long-term survival, but there was no such correlation in ALL.

- BACKGROUND. Today, intensive therapy that includes high-close melphalan with autologous stein cell transplantation (ASCT) is considered standard therapy in younger patients with newly diagnosed myeloma. When the current trial was initiated, combined vincristine, doxorubicin, and dexamethasone (VAD) was the most commonly used induction therapy before ASCT and yielded rapid major responses without interfering with stein cell harvest. However, the administration of VAD demands a central venous access, and well-described toxicities are associated with the therapy. This randomized trial, which was initiated in 2001 by the Nordic Myeloma Study Group, was an attempt to bring a larger portion of patients to ASCT more quickly. METHODS. Patients were randomized to receive either 3 cycles of VAD or 2 courses of cyclophosphamide plus dexamethasone (Cy-Dex) (cyclophosphamide at a dose of 1000 mg/m(2) on Day 1 and dexamethasone at a dose of 40 mg per day on Days 1-4 and 9-12, repeated on Day 22) as initial therapy followed by stein cell mobilization, harvest, and finally ASCT. RESULTS. No significant difference was observed in the proportion of patients undergoing ASCT (VAD [86%] vs Cy-Dex [87%]). During the first 4 months after the initiation of therapy, the mortality rates were 5.8% for VAD and 1.9% for Cy-Dex (P =.08). The response rates after ASCT were comparable (partial response or better: VAD: 80% vs Cy-Dex: 81%). In both groups, the median event-free survival was 29 months, and the overall survival rate at 3 years was 75%. CONCLUSIONS. The current results indicated that Cy-Dex before ASCT has efficacy comparable to that of VAD. It also demonstrated that a short course of alkylater therapy using cyclophosphamide does not affect stem cell harvest or transplantation.
