Multicenter StudySurvival of patients with hematological malignancy admitted to the intensive care unit: prognostic factors and outcome compared to unselected medical intensive care unit admissions, a parallel group study.
Improved survival in patients with hematological malignancy (HM) admitted to the intensive care unit (ICU) has largely been reported in uncontrolled cohorts from single academic institutions. We compared hospital mortality between 147 patients with HM and 147 general medical admissions to five non-specialist ICUs. The proportion of patients surviving to hospital discharge was significantly worse in patients with HM (27% vs. 56%; p < 0.001). ⋯ For patients with HM, culture proven infection, age, MV and inotropes were negative predictors. Disease-specific factors including hematological diagnosis, neutropenia, remission status, prior stem cell transplant, time from diagnosis to admission and degree of prior treatment were not predictive. Overall survival of patients with HM was worse than that recently reported from specialist units.

Multicenter Study Clinical TrialDose-dense high-dose methylprednisolone and rituximab in the treatment of relapsed or refractory high-risk chronic lymphocytic leukemia.
This study evaluated the efficacy and safety of dose-dense high-dose methylprednisolone (HDMP) plus rituximab (Rtx) in patients with high-risk CLL. Twenty-nine patients with relapsed or progressive CLL with adverse cytogenetics (17p deletion, TP53 mutation, 11q deletion, and/or trisomy 12) and/or progression within 12 months of fludarabine treatment were included. HDMP (1 g/m(2)) was administered daily for 5 days of each treatment course. ⋯ After 22 months, the median progression-free and overall survivals were 12 and 31 months, respectively. The most frequent toxicity was hyperglycemia, and three deaths occurred in the study. Dose-dense treatment with HDMP and Rtx is an effective therapy with a favorable safety profile in patients with high-risk CLL, including those with 17p deletion/TP53 mutation.

Multicenter StudyCytogenetic characterisation in Chinese patients with chronic lymphocytic leukemia: a prospective, multicenter study on 143 cases analysed with interphase fluorescence in situ hybridisation.
Chronic lymphocytic leukemia (CLL) is infrequent in Chinese people. Conventional cytogenetic analysis underestimates the frequency of chromosome aberrations in CLL due to the low rate of spontaneous mitoses. The aim of this study was to prospectively explore the frequency of chromosomal abnormalities in Chinese patients with CLL using interphase fluorescence in situ hybridisation (FISH) and probes for 12 centromere, 13q14, 14q32, 17p13, 11q22 and 6q23 on 143 patients with CLL. ⋯ In early stage (Binet A), del(13q14) aberration was more frequent than in Binet B and C (61.5% vs. 31.9% and 41.9%) (P=0.021). Patients with advanced stage (Binet C) had more frequent del(17p13) aberration than in Binet A and B (32.3% vs. 9.2% and 4.3%) (P=0.008). It was showed that the frequencies of the chromosomal abnormalities in our study population were similar to the frequencies in Western countries.

Multicenter StudyHigh anti-lymphoma activity of bendamustine/mitoxantrone/rituximab in rituximab pretreated relapsed or refractory indolent lymphomas and mantle cell lymphomas. A multicenter phase II study of the German Low Grade Lymphoma Study Group (GLSG).
On the basis of a preceding phase I study, the current trial explored bendamustine in combination with mitoxantrone and rituximab (BMR) in patients with stage III/IV relapsed or refractory indolent lymphomas and mantle cell lymphoma (MCL) with or without prior rituximab containing chemo-immunotherapy (R-chemo) treatment. Therapy consisted of bendamustine 90 mg/m(2) days 1 + 2, mitoxantrone 10 mg/m(2) day 1, rituximab 375 mg/m(2) day 8. Treatment was repeated on day 29 for a total of four cycles. ⋯ Treatment related toxicities of grade 3/4 comprised a reversible myelosuppression (10% anemia, 78% leukocytopenia, 46% granulocytopenia, 16% thrombocytopenia). However, unexpected hospitalisations were necessary after 4% of BMR-application only. BMR is a very effective new outpatient immuno-chemotherapy with low toxicity for patients with relapsed/refractory FL, MCL and other indolent lymphomas.

Multicenter Study Comparative StudyMulticentre phase II study of the baseline BEACOPP regimen for patients with advanced-stage Hodgkin's lymphoma.
A German Hodgkin's lymphoma (HL) study group designed the BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, prednisolone) regimen. In the BEACOPP regimen, treatment intervals were shortened and the dose-intensity was increased compared with those in the ABVD regimen (doxorubicin, bleomycin, vinblastine and darcarbacine), resulting in a long-term disease-free survival rate of approximately 75-80%. In the present study, we evaluated the safety and efficacy of the BEACOPP regimen. ⋯ The BEACOPP regimen for advanced-stage HL showed an excellent complete remission rate and high efficacy even in stage III/IV patients. However, a long-term risk of the BEACOPP regimen is the development of secondary leukemia or myelodysplastic syndrome. Therefore, long-term follow-up of these patients, including monitoring for toxicities, is necessary.
