Triplet vs doublet lenalidomide-containing regimens for the treatment of elderly patients with newly diagnosed multiple myeloma
Lenalidomide-dexamethasone improved outcome in newly diagnosed elderly multiple
myeloma patients. We randomly assigned 662 patients who were age \u202165 years or
transplantation-ineligible to receive induction with melphalan-prednisone-lenalidomide
(MPR) or cyclophosphamide-prednisone-lenalidomide (CPR) or lenalidomide plus lowdose
dexamethasone (Rd). The primary end point was progression-free survival (PFS) in
triplet (MPR and CPR) vs doublet (Rd) lenalidomide-containing regimens. After a median
follow-up of 39 months, the medianPFSwas22 months for the triplet combinations and 21
months for the doublet (P 5 .284). The median overall survival (OS) was not reached in
either arms, and the 4-year OS was 67% for the triplet and 58% for the doublet arms (P 5 .709). By considering the 3 treatment arms
separately, no difference in outcome was detected among MPR, CPR, and Rd. The most common grade \u20213 toxicity was neutropenia:
64% in MPR, 29% in CPR, and 25% in Rd patients (P < .0001). Grade \u20213 nonhematologic toxicities were similar among arms and were
mainly infections (6.5% to 11%), constitutional (3.5% to 9.5%), and cardiac (4.5% to 6%), with no difference among the arms. In
conclusion, in the overall population, the alkylator-containing tripletsMPRandCPRwere not superior to the alkylator-free doublet Rd,
which was associated with lower toxicit
CPX-351 treatment in secondary acute myeloblastic leukemia is effective and improves the feasibility of allogeneic stem cell transplantation: results of the Italian compassionate use program
Secondary acute myeloid leukemia (sAML) poorly responds to conventional treatments and allogeneic stem cell transplantation (HSCT). We evaluated toxicity and efficacy of CPX-351 in 71 elderly patients (median age 66 years) with sAML enrolled in the Italian Named (Compassionate) Use Program. Sixty days treatment-related mortality was 7% (5/71). The response rate at the end of treatment was: CR/CRi in 50/71 patients (70.4%), PR in 6/71 (8.5%), and NR in 10/71 (19.7%). After a median follow-up of 11 months relapse was observed in 10/50 patients (20%) and 12 months cumulative incidence of relapse (CIR) was 23.6%. Median duration of response was not reached. In competing risk analysis, CIR was reduced when HSCT was performed in first CR (12 months CIR of 5% and 37.4%, respectively, for patients receiving (=20) or not (=30) HSCT, p = 0.012). Twelve-months OS was 68.6% (median not reached). In landmark analysis, HSCT in CR1 was the only significant predictor of longer survival (12 months OS of 100 and 70.5%, for patients undergoing or not HSCT in CR1, respectively, p = 0.011). In conclusion, we extend to a real-life setting, the notion that CPX is an effective regimen for high risk AML patients and may improve the results of HSCT
Brentuximab vedotin consolidation after autologous stem cell transplantation for Hodgkin lymphoma: A Fondazione Italiana Linfomi real-life experience
The standard management for relapsed or refractory classical Hodgkin lymphoma (cHL) is salvage therapy followed by autologous stem cell transplantation (ASCT). This strategy allows almost 50% of patients to be cured. Post-ASCT maintenance treatment with brentuximab vedotin (BV) confers improved progression-free survival (PFS) to cHL patients at high risk of relapse. We investigated the outcome of 105 cHL patients receiving post-ASCT BV maintenance in the real-life setting of 23 Italian hematology centers. This population included naïve patients and those previously exposed to BV. Median follow-up was 20 months. Patients presented a median of two lines of treatment pre-ASCT, with 51% receiving BV. Twenty-nine percent of patients had at least two high-risk factors (refractory disease, complete response [CR] less than 12 months, extranodal disease at relapse), while 16% presented none. At PET-CT, a Deauville score (DS) of 1–3 was reported in 75% and 78% of pre- and post-ASCT evaluations, respectively. Grade 3–4 adverse events (AEs), mainly peripheral neuropathy, were observed in 16% of patients. Three-year PFS and overall survival (OS) were 62% and 86%, respectively. According to BV exposure, 3-year PFS and OS were 54% and 71%, respectively, for naïve and 77% and 96%, respectively, for previously exposed patients. Refractory disease (hazard ratio [HR] 4.46; p = 0.003) and post-ASCT DS 4–5 (HR 3.14; p = 0.005) were the only two factors significantly associated with PFS reduction in multivariable analysis. Post-ASCT BV maintenance is an effective, safe treatment option for cHL naïve patients and those previously exposed to BV
Defect analysis in mission-critical software systems: a detailed investigation
The practice of defect analysis is recognized as an essential task for software process measurement, yet its
effective application in the industrial development of large-scale software systems raises several challenges.
We report the results of a study conducted at SELEX ES - a large system integrator leader in the market of
software-intensive mission-critical systems. The article describes the defect analysis approach that we tailored to evaluate the software development process with respect to the quality of produced software and
its relation with the required effort. Three key phases of the process were addressed, regarding the software
implementation, the testing phase and the prerelease defect fixing activity, over a set of six computer software configuration items developed from 2009 to 2012 for the naval and maritime domain product line.
The analysis highlighted efficiency bottlenecks in each of the monitored phases, providing company engineers with insights about room for process improvement. The implemented approach, the observed phenomena and the inferred conclusions are of support to practitioners coping with systems, development models and
industrial environments similar to the considered one
