Randomized Controlled Trial Multicenter Study Comparative StudySix versus eight doses of rituximab in patients with aggressive B cell lymphoma receiving six cycles of CHOP: results from the "Positron Emission Tomography-Guided Therapy of Aggressive Non-Hodgkin Lymphomas" (PETAL) trial.
Standard first-line treatment of aggressive B cell lymphoma comprises six or eight cycles of cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) plus eight doses of rituximab (R). Whether adding two doses of rituximab to six cycles of R-CHOP is of therapeutic benefit has not been systematically investigated. The Positron Emission Tomography-Guided Therapy of Aggressive Non-Hodgkin Lymphomas (PETAL) trial investigated the ability of [18F]-fluorodesoxyglucose PET scanning to guide treatment in aggressive non-Hodgkin lymphomas. ⋯ Differences between FL grade 3a and FL grade 3b were not apparent. The results were confirmed in a Cox proportional hazard regression model and a propensity score matching analysis. In conclusion, adding two doses of rituximab to six cycles of R-CHOP did not improve outcome in patients with aggressive B cell lymphomas and a fast metabolic treatment response.

Multicenter Study Clinical TrialThe pharmacokinetics and pharmacodynamics of busulfan when combined with melphalan as conditioning in adult autologous stem cell transplant recipients.
Busulfan (Bu) is an alkylating agent widely used in conditioning regimes prior to stem cell transplantation (SCT), most commonly in combination with cyclophosphamide (Bu-cy) or fludarabine (Bu-flu) as myeloablative conditioning prior to allograft or with high-dose melphalan (Bu-mel) prior to autologous SCT. Despite many decades of Bu use, initially orally but now intravenously (IV), a paucity of pharmacokinetic (PK) and pharmacodynamic (PD) data exists to inform evidence-based guidelines as how best to balance the efficacy and toxicity of this agent. This is a non-randomized retrospective real-world study at three hospitals investigating the role of PK guidance in dosing Bu in the setting of IV Bu-mel autologous SCT. ⋯ On D-5, within the weight-based cohort, the mean AUCs were 12% higher than anticipated based on initial D-7 PK. No correlation between AUC and grade 3-4 transplant-related toxicities were observed, although only three patients had AUCs > 6000 μmol min/day. These results suggest that PK-directed Bu dosing may be of benefit in achieving a target level of drug exposure, with larger studies needed to determine the clinical significance of this strategy.

Multicenter StudyBrentuximab vedotin as salvage treatment in Hodgkin lymphoma naïve transplant patients or failing ASCT: the real life experience of Rete Ematologica Pugliese (REP).
Brentuximab vedotin (BV) shows a high overall response rate (ORR) in relapsed/refractory (R/R) Hodgkin lymphoma (HL) after autologous transplant (ASCT). The aim of this multicenter study, conducted in nine Hematology Departments of Rete Ematologica Pugliese, was to retrospectively evaluate the efficacy and safety of BV as salvage therapy and as bridge regimen to ASCT or allogeneic transplant (alloSCT) in R/R HL patients. Seventy patients received BV. ⋯ The most common adverse events were peripheral neuropathy (50%), neutropenia (29%) and anemia (12%). These data suggest that BV is well tolerated and very effective in R/R HL, producing a substantial level of CR. BV may also be a key therapeutic agent to achieve good disease control before transplant, improving post- transplant outcomes, also in refractory and heavily pretreated patients, without significant overlapping toxicities with prior therapies.

Randomized Controlled Trial Multicenter StudyBortezomib and low-dose dexamethasone with or without continuous low-dose oral cyclophosphamide for primary refractory or relapsed multiple myeloma: a randomized phase III study.
This phase III, open-label, randomized, controlled study aimed to evaluate the benefit of adding continuous low-dose oral cyclophosphamide to bortezomib-dexamethasone in patients with primary relapsed/refractory multiple myeloma. Patients were randomized 1:1 to receive up to eight 3-week cycles of bortezomib (1.3 mg/m2) and dexamethasone (20 mg; VD; n = 48) or bortezomib-dexamethasone plus oral cyclophosphamide (50 mg; VCD; n = 48). Median time to progression (primary endpoint) was slightly longer in the VD versus VCD group (12.6 vs 9.9 months, P = 0.192), and the hazard ratio for disease progression was in favor of VD (hazard ratio = 0.71, 95% confidence interval = 0.43-1.19, P = 0.196). ⋯ Further trials are needed to determine whether addition of cyclophosphamide to VD at a different dose/schedule confers clinical benefit. This study was terminated prematurely, with insufficient sample size to adequately compare the arms; the results should, therefore, be considered descriptive. This trial is registered: EudraCT Number 2008-003213-27; ClinicalTrials.gov NCT00813150.

Multicenter Study Clinical TrialPalliative home care for patients with advanced haematological malignancies-a multicenter survey.
Patients with advanced haematological malignancies in non-curative settings suffer from complex physical symptoms and psychosocial distress, comparable to patients with solid tumour entities. Nevertheless, numerous problems at the interface between haematology and palliative home care have been described. From January 2011 until October 2014, we performed a retrospective, multicenter analysis of all patients with haematological malignancies (ICD 10: C81-C95) being treated by the respective specialized palliative home care (SAPV) team. ⋯ Patients suffering from advanced haematological malignancies were statistically underrepresented in SAPV, and SAPV was installed rather at the very last days of life. By far, more patients were able to die outside a hospital as compared to reference cohorts of haematological patients not being treated in SAPV. The spectrum of documented problems is comparable to other patient cohorts being treated in SAPV; therefore, the options and benefits of palliative home care should be incorporated in palliative haematological treatment concepts more vigorously and consequently.
