Evaluation of the CLL-IPI in relapsed and refractory chronic lymphocytic leukemia in idelalisib phase-3 trials.
The CLL-IPI is a risk-weighted prognostic model for previously untreated patients with chronic lymphocytic leukemia (CLL), but has not been evaluated in patients with relapsed CLL or on novel therapies. We evaluated the CLL-IPI in 897 patients with relapsed/refractory CLL in 3 randomized trials testing idelalisib (PI3Kδ inhibitor). The CLL-IPI identified patients as low (2.2%), intermediate (12.8%), high (48.7%), and very high (36.2%) risk and was prognostic for survival (log-rank p < .0001; C-statistic 0.706). ⋯ The CLL-IPI is prognostic for survival in relapsed CLL and with idelalisib therapy. However, low/intermediate risk is uncommon, and regression parameters of individual factors in this risk-weighted model appear different in relapsed CLL. Reassessment of the weighting of the individual variables might optimize the model in this setting.

Meta Analysis Comparative StudyA meta-analysis of autologous transplantation for newly diagnosed multiple myeloma in the era of novel agents.
To evaluate the role of high-dose melphalan plus autologous stem-cell transplantation (ASCT) as consolidation therapy for patients with newly diagnosed multiple myeloma (NDMM) in the era of novel agents, we undertook this meta-analysis. Medline, Embase, the Cochrane controlled trials register, the SCI, ASH, EHA, and ASCO were searched for clinical trials including high-dose chemotherapy plus ASCT for patients with NDMM. Finally, we identified four RCTs of ASCT versus novel agents based consolidations, and 10 single-arm prospective trials of ASCT alone. ⋯ Of note, subgroup analysis indicated that ASCT could significantly improve OS (HR =0.49, p = .0004) when compared to alkylating agent-based regimens plus lenalidomide consolidation. In summary, response quality and PFS improved further over ASCT in the era of novel agents. ASCT could improve survival than alkylating agent-based regimens plus lenalidomide consolidations for patients with NDMM.
