Incidence and risk factors of post-engraftment invasive fungal disease in adult allogeneic hematopoietic stem cell transplant recipients receiving oral azoles prophylaxis.
Studies that analyze the epidemiology and risk factors for invasive fungal disease (IFD) after engraftment in alloSCT are few in number. This single-center retrospective study included 404 alloSCT adult recipients surviving >40 days who engrafted and were discharged without prior IFD. All patients who received ⩾20 mg/day of prednisone were assigned to primary oral prophylaxis (itraconazole or low-dose voriconazole). ⋯ The post-engraftment IFD score stratified patients into low risk (0-1 factor, CI 0.7%), intermediate risk (2 factors, CI 9.9%) and high risk (3-5 factors, CI 24.7%) (P<0.0001). The antifungal prophylaxis strategy failed to prevent post-engraftment IFD in 11% of alloSCT. Our risk score could be useful to implement risk-adapted strategies using antifungal prophylaxis after engraftment.

Human herpesvirus 6B reactivation and delirium are frequent and associated events after cord blood transplantation.
Human herpesvirus 6B (HHV-6B) frequently reactivates after cord blood transplantation (CBT). We previously reported an association between HHV-6B reactivation and delirium after hematopoietic cell transplantation. ⋯ In addition, intensified prophylaxis with high-dose valacyclovir mitigated HHV-6B reactivation (adjusted hazard ratio, 0.39; 95% CI, 0.14-1.08). Larger trials are needed to explore the utility of HHV-6B prophylaxis after CBT.

Salvage bortezomib-dexamethasone and high-dose melphalan (HDM) and autologous stem cell support (ASCT) in myeloma patients at first relapse after HDM with ASCT. A phase-2 trial.
Until recently, only retrospective studies had been published on salvage high-dose melphalan (HDM) with autologous stem cell 'transplantation' (ASCT). In a prospective, nonrandomized phase-2 study, we treated 53 bortezomib-naïve patients with bortezomib-dexamethasone as induction and bortezomib included in the conditioning regimen along with the HDM. Median progression-free survival (PFS), time to next treatment (TNT) and overall survival (OS) after start of reinduction therapy were 21.6, 22.8 and 46.6 months, respectively. ⋯ Bortezomib-HDM conditioning combo was feasible, and toxicity was as expected for patients treated with bortezomib and ASCT. In conclusion, in bortezomib-naïve patients treated at first relapse with salvage ASCT including bortezomib, PSF and TNT did not differ significantly from initial ASCT and median OS was almost 5.5 years with acceptable toxicity. A recent prospective randomized study confirms salvage ASCT to be an effective treatment.

Clinical TrialPrognostic understanding, quality of life and mood in patients undergoing hematopoietic stem cell transplantation.
Little is known about how patients undergoing hematopoietic stem cell transplantation (HCT) and their family caregivers (FC) perceive their prognosis. We examined prognostic understanding in patients undergoing HCT and their FC and its relationship with quality of life (QOL) and mood. We conducted a longitudinal study of patients (and FC) hospitalized for HCT. ⋯ However, 77.6% of patients and 71.7% of FC reported a discordance and more optimistic prognostic perception compared to the oncologist (P<0.0001). Patients with a concordant prognostic understanding with their oncologists reported worse QOL (β=-9.4, P=0.01) and greater depression at baseline (β=1.7, P=0.02) and over time ((β=1.2, P<0.0001). Therefore, Interventions are needed to improve prognostic understanding, while providing patients with adequate psychological support.

Multicenter Study Comparative StudyComparison of upfront tandem autologous-allogeneic transplantation versus reduced intensity allogeneic transplantation for multiple myeloma.
We performed a retrospective analysis of the European Group for Blood and Marrow Transplantation database comparing the outcomes of multiple myeloma patients who received tandem autologous followed by allogeneic PSCT (auto-allo) with the outcomes of patients who underwent a reduced intensity conditioning allograft (early RIC) without prior autologous transplant. From 1996 to 2013, we identified a total of 690 patients: 517 patients were planned to receive auto-allo and 173 received an early RIC allograft without prior autologous transplant. With a median follow-up of 93 months, 5-year PFS survival was significantly better in the auto-allo group, 34% compared with 22% in the early RIC group (P<0.001). ⋯ The non-relapse mortality rate was lower in the auto-allo group than in the early RIC group, with 1- and 3-year rates of 8% and 13% vs 20% and 28%, respectively (P<0.001). The relapse/progression rate was similar in the two groups, with 5-year rates of 50% for auto-allo and 46% for early RIC (P=0.42). These data suggest that planned tandem autologous allograft can improve overall survival compared with upfront RIC allograft alone in patients with multiple myeloma.
