Abstract Background: High-dose chemotherapy with autologous stem cell support (HDT) has been proven effective in relapsed aggressive Non-Hodgkin lymphoma (NHL). However, conflicting results of HDT as part of first-line treatment have been reported in randomized controlled trials (RCTs). Here, we report our updated meta-analysis to better define the role of HDT in these patients. Methods: RCTs were identified by computerized search and handsearching of conference proceedings. Data extraction and quality assessment was performed independently by two reviewers. First authors were contacted to request individual patient data. Eight investigators provided us with individual patient data, for five trials data were extracted from survival curves. The hazard ratio (HR) was used as a measure of treatment effect; the inverse variance method (fixed effect model) was used for pooling. The relative risk was determined for binary data. Results: 15 RCTs including 3079 patients were eligible for this meta-analysis. Overall treatment-related mortality was 6.0% in the HDT group and not significantly different compared to conventional chemotherapy (RR 1.33, p=0.59). Analysis of 13 studies including 2018 patients showed significantly higher CR rates in the group receiving HDT (RR 1.10, p=0.004). However, HDT did not have an effect on OS, when compared to conventional chemotherapy. The pooled HR was 1.04 (p=0.58). There was no statistical heterogeneity among the trials and sensitivity analyses underscored the robustness of these results. Subgroup analysis of prognostic groups according to IPI did not show any survival difference between HDT and controls in 12 trials (low and low-intermediate risk IPI: HR 1.41, high-intermediate and high risk IPI: HR 0.97). Event-free survival (EFS) also showed no significant difference between HDT and CT (HR 0.93, p=0.31). We incorporated several additional variables to possibly identify other risk factors such as the proportions of diffuse large cell lymphoma, protocol adherence, the HDT strategy used, response status of patients before HDT, the conditioning regimen used, and methodological issues. However, our analyses demonstrate that the results described here are not related on either of these factors. Conclusion: Despite higher CR rates, there is no benefit for HDT in patients with aggressive NHL when incorporated in first-line treatment.

Abstract Abstract 1219 Poster Board I-241 Background High-dose chemotherapy followed by autologous stem cell transplantation (ASCT) has been evaluated in several trials and has shown feasibility as first-line treatment of primary central nervous system lymphoma (PCNSL). However, the best conditioning regimen is still to be identified and high-dose chemotherapy of busulfan, cyclophosphamide, and etoposide (BuCyE) has not been tried although the regimen was shown to be effective for leukemia and systemic non-Hodgkin's lymphoma. Methods Between May 2005 and November 2008, 12 consecutive patients of PCNSL with pathologic diagnosis of diffuse large-B cell lymphoma were treated with the intent of upfront ASCT at Asan Medical Center, Seoul, Korea. We retrospectively analyzed the results of these patients. The treatment included induction chemotherapy of high-dose methotrexate/cytarabine (Abrey et al., JCO 21:4151, 2003), followed by BuCyE chemotherapy consisting of iv busulfan (3.2mg/kg from day -7 to day -5), iv cyclophosphamide (50mg/kg from day -3 to day -2), and etoposide (200mg/m2 every 12 hours from day -5 to day -4), and ASCT. Whole brain radiotherapy (WBRT) was reserved for patients who failed to achieve complete response (CR) after ASCT. Results Median age was 50 years (range, 33-65) and 9 were male. The test of cerebrospinal fluid (CSF) cytology came out to be positive for 3 patients. Eight patients achieved CR and 4 gained partial response (PR) after induction chemotherapy. All 12 patients managed to complete ASCT. Following ASCT, additional 2 patients gained CR, resulting in total number of 10 patients (83.3%). Patients who failed to reach CR were further treated with WBRT and 2 more patients achieved CR. Median duration of first CR was 12.8 months (95% confidence interval [CI], 4.6-20.9) at a median follow-up of 23.8 months (range, 8.8-50.7). Relapse of disease occurred in 7 patients (58.3%) and 5 of them were given salvage treatment (Table 1). Two patients could regain CR and sustained remission for more than 2 years. Two patients had died of disease at the time of analysis. Median event-free survival (EFS) from the first day of induction chemotherapy was 15.0 months (95% CI, 8.3-21.8) and median overall survival (OS) was not reached. The 2-year OS probability was 78.8% and 2-year EFS was 25.7%. No patient experienced veno-occlusive disease or treatment-related mortality (TRM). Three patients among those who were treated with WBRT or intrathecal chemotherapy developed leukoencephalopathy. Conclusion BuCyE chemotherapy might be an option of conditioning regimen for ASCT considering high CR rate of 83.3% and favorable toxicity profile in the treatment of PCNSL. However, high relapse rate of 58.3% suggests that more optimization of induction and conditioning chemotherapy is still required. Disclosures No relevant conflicts of interest to declare.
