High-dose chemotherapy before autologous transplantation is a therapeutic option as consolidation in primary or relapsed lymphoma. Even if BEAM conditioning is generally used, alternative conditioning regimens have been published. The purpose of this study was to assess the outcome of 177 adult patients with lymphoma whose conditioning treatment included a BAM (busulfan, aracytine, and melphalan) regimen. With a median follow-up of 17.4 months, 2-year estimates of overall survival and progression-free survival for the entire group were 87% and 70.5%, respectively. Mucositis was the main reported complications and infectious episodes were described in 80.2% of patients. According to multivariate analysis, high performance status and age at diagnosis were adverse factors for survival and increased the risk of disease relapse and death. Despite its limitations, this retrospective study suggests that BAM combination is a valid conditioning regimen in lymphoma patients, with an acceptable rate of toxicity. [ABSTRACT FROM AUTHOR]

Summary: Splenectomy in addition to immunotherapy with rituximab can provide quick and sometimes durable disease control in patients with splenic marginal zone lymphoma (SMZL). However, systemic chemotherapy is ultimately required in many cases. The BRISMA (Bendamustine‐rituximab as first‐line treatment of splenic marginal zone lymphoma)/IELSG (International Extranodal Lymphoma Study Group)36 trial is an open‐label, single arm phase II study designed by the IELSG in cooperation with the Fondazione Italiana Linfomi and the lymphoma Study Association according to Simon's two‐stage method. The primary endpoint was complete response rate. Fifty‐six patients with SMZL diagnosis confirmed on central revision were treated with bendamustine (90 mg/m2 days 1, 2) and rituximab (375 mg/m2 day 1) every 28 days for six cycles (B‐R). The overall response and CR rates were 91% and 73%, respectively. Duration of response, progression‐free survival and overall survival at 3 years were 93% (95% confidence interval [CI] 81–98), 90% (95% CI 77–96) and 96% (95% CI 84–98), respectively. Toxicity was mostly haematological. Neutropenia grade ≥3 was recorded in 43% of patients; infections and febrile neutropenia in 5·4% and 3·6%. Overall, 14 patients (25%) experienced serious adverse events. Five patients (9%) went off‐study because of toxicity and one patient died from infection. In conclusion, B‐R resulted in a very effective first‐line regimen for SMZL. Based on the results achieved in the BRISMA trial, B‐R should be considered when a chemotherapy combination with rituximab is deemed necessary for symptomatic SMZL patients. [ABSTRACT FROM AUTHOR]

Summary: Tandem stem cell transplantation (SCT) is an option for high‐risk relapsed/refractory Hodgkin Lymphoma (HL) patients. We evaluated the tolerance/efficacy of double autologous or autologous SCT (ASCT) followed by allogenic SCT (alloSCT) in 120 HL patients prospectively registered on a French nationwide database. Median age was 26 (14–56) years. Complete remission rate was 60%, including 33% after a single line, and another 27% after two or more salvage regimens. Partial response rate was 32%, and 8% suffered treatment failure. Overall, 115 (96%) patients underwent a first ASCT, and 73 (61%) had a tandem SCT, including alloSCT in 44 (60%) and ASCT in 29 (40%). The median follow‐up was 43 months (4.8–73.7 months). The two‐year progression‐free survival rate for the whole population and for patients receiving tandem transplant was 56% (95% confidence interval [CI]: 46–65%) and 71% (95% CI: 49–84%), respectively. Among tandem transplants, we observed 20 deaths (17%), 10 of which were transplant‐related (6 alloSCT and 4 ASCT). We suggest that tandem SCT is efficient in high‐risk relapsed/refractory HL patients, although transplant‐related mortality remains high. The benefit of tandem SCT should be balanced with the efficacy of Brentuximab vedotin‐based post‐transplant consolidative strategies in high‐risk relapsed/refractory HL patients.

The article discusses a study which examined the clinical and biological characteristics of patients with both myelodysplastic syndromes/acute myeloid leukaemia (MDS/AML) and lymphoma. Topics include the complications of cytotoxic chemotherapy (CT) and radiotherapy (RT), the occurrence of MDS/AML in patients with Hodgkin lymphoma (HL) or non-Hodgkin lymphoma (NHL), and the diagnosis of MDS/AML.

Toxic effects of high dose therapy (HDT) combined with autologous stem cell transplantation (ASCT) can lead to life-threatening conditions that may require intensive care unit (ICU) admission. We conducted a retrospective observational study over a 10-year period of all patients admitted to the ICU within 3 months after HDT/ASCT for lymphoma. Among the 532 patients treated by HDT/ASCT at our hospital, 27 (5%) were admitted to the ICU. Infections accounted for 88% (n= 24) of diagnoses, in whom 50% were microbiologically documented. Primary sources of infections were neutropenic enterocolitis (n= 9, 33%) and pneumonia (n= 9, 33%). Bacteria were identified in 83% of documented infections. ICU mortality was 18.5% (n= 5), representing 0.9% of the 532 patients. Among the 22 ICU survivors, 72.7% (n= 16) were alive and in complete remission 6 months after ICU discharge. In our experience, maximal intensive care support is justified for HDT/ASCT recipients with severe complications. [ABSTRACT FROM AUTHOR]

An unusual case of pleural empyema related to Nocardia farcinica and Ureaplasma urealyticum , occurring after autologous haematopoietic stem cell transplantation in a 30-year-old patient with lymphoma, is reported. This case illustrates the role of repeated and comprehensive microbiological investigations and the contribution of molecular techniques in reaching the aetiological diagnosis. [ABSTRACT FROM AUTHOR]
