Short- and long-term outcomes of adult allogeneic hematopoietic stem cell transplant patients admitted to the intensive care unit in the peritransplant period.
Survival of allogeneic hematopoietic stem cell transplant (aHSCT) recipients in the intensive care unit (ICU) has been poor. We retrospectively analyzed the short- and long-term outcomes of aHSCT patients admitted to the ICU over a 12-year period. Of 1235 adult patients who had aHSCT between 2002 and 2013, 161 (13%) were admitted to the ICU. ⋯ While hospital mortality decreased from 69% to 44%, long-term survival (LTS) remained unchanged. Late deaths, due to causes not associated with the ICU such as relapse and graft-versus-host disease, increased. As thresholds for transplant are lowered, improvements in ICU outcomes for aHSCT recipients may be limited.

Loss of RUNX3 expression is an independent adverse prognostic factor in diffuse large B-cell lymphoma.
Runt-related transcription factor-3 (RUNX3) is an apoptotic factor correlated with tumorigenesis and cancer progression. Enhancer of zeste homolog-2 (EZH2), a histone methyltransferase, has been shown to mediate silencing of RUNX3. We investigated RUNX3 and EZH2 expression in diffuse large B-cell lymphoma (DLBCL). ⋯ Results suggest a role for the RUNX3 gene in the pathogenesis of DLBCL. Loss of RUNX3 expression strongly correlated with adverse prognosis, independent of subtype. Further studies are warranted to elucidate the biology and prognostic utility of RUNX3 in DLBCL.

Detection of bone marrow involvement in newly diagnosed post-transplant lymphoproliferative disorder: (18)F-fluorodeoxyglucose positron emission tomography/computed tomography versus bone marrow biopsy.
Detecting bone marrow involvement (BMI) in lymphoma is important as it adversely affects stage. Bone marrow biopsy (BMB) remains the standard to detect BMI but is prone to sampling error. We retrospectively investigated whether (18)F-fluorodeoxyglucose positron emission tomography with computed tomography ((18)F-FDG-PET/CT) could identify BMI in patients with post-transplant lymphoproliferative disorder (PTLD) with sufficient accuracy in comparison with staging BMB. ⋯ Based on our criteria, six patients (24%) were considered positive for BMI on (18)F-FDG-PET/CT compared to one by BMB. Although we cannot completely exclude false positive results on (18)F-FDG-PET/CT, our data indicate a significantly higher sensitivity of (18)F-FDG-PET/CT compared to BMB (100% vs 17%) but similar specificity. These data confirm the high diagnostic performance of (18)F-FDG-PET/CT for detecting BMI, but prospective studies are needed to determine whether (18)F-FDG-PET/CT could indeed replace staging BMB in PTLD.

Multicenter StudySafety and efficacy of rituximab plus bendamustine in relapsed or refractory diffuse large B-cell lymphoma patients: an Italian retrospective multicenter study.
Relapsed or refractory diffuse large B-cell lymphoma (DLBCL) not suitable for high dose chemotherapy with autologous stem cell transplantation (ASCT) has a dismal prognosis and no standard therapy. We designed an Italian multicenter retrospective study aimed at evaluating the safety and efficacy of rituximab plus bendamustine (R-B) as salvage treatment in patients not eligible for ASCT because of age and/or comorbidity or in patients with post-ASCT recurrence. Fifty-five patients with a median age of 76 years were included. ⋯ Eleven patients are still alive and in complete remission at last follow-up (12-71 months). Toxicity was moderate, mainly grades 1 and 2. R-B showed promising efficacy results with an acceptable toxicity profile and should be further investigated, possibly in combination with novel drugs.

Implemented myeloma management with whole-body low-dose CT scan: a real life experience.
A total of 318 consecutive myeloma patients underwent whole-body low-dose CT scan (WBLDCT) at baseline and during follow-up as a radiological assessment of lytic lesions in place of skeletal X-ray survey. After WBLDCT baseline assessment, 60% had bone involvement. The presence of lytic lesions represented the only met CRAB (hyperCalcaemia, Renal insufficiency, Anaemia, Bone lesions) criteria in 29% of patients. ⋯ Radiological progression was documented in 9% of the population with available follow-up. Additional pathological incidental findings were detected in 28 patients (14.5%), most located in the chest region (68%). In conclusion, our real-life data shows that WBLDCT scan represents a reliable imaging tool for decision-making process for multiple myeloma management in different disease phases, providing significant additional information on the presence of soft tissues plasmacytomas detection as well as the presence of pathological incidental findings.
