Nonpegylated liposomal doxorubicin combination regimen in patients with diffuse large B-cell lymphoma and cardiac comorbidity. Results of the HEART01 phase II trial conducted by the Fondazione Italiana Linfomi
The purpose of this phase 2, multicenter study was to determine the activity and safety of nonpegylated liposomal doxorubicin as part of "R-COMP" combination in patients with diffuse large B-cell lymphoma and coexisting cardiac disorders. The study was conducted using a Bayesian continuing assessment method using complete remission rate and rate of cardiac events as study endpoints. Between November 2009 and October 2011, 50 evaluable patients were enrolled (median age, 76\ua0years). Median baseline left ventricular ejection fraction (LVEF) was 60%. Ischemic cardiopathy was the most frequent preexisting cardiac disorder (35%), followed by atrial fibrillation (15%), left ventricular hypertrophy (13%), and baseline LVEF <50% (12%). Based on the intent to treat analysis, overall response rate was 72%, including 28 patients in complete remission (complete remission rate, 56%), and 8 in partial remission (16%). At the end of treatment, grades 3 to 4 cardiac events were observed in 6 patients. No significant modifications from baseline values of LVEF were observed during treatment and follow-up. Nonpegylated liposomal doxorubicin instead of doxorubicin in the R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone) regimen is a feasible option for patients with diffuse large B-cell lymphoma presenting with concomitant cardiac disorders

Interpretative and predictive modelling of Joint European Torus collisionality scans
Transport modelling of Joint European Torus (JET) dimensionless collisionality scaling experiments in various operational scenarios is presented. Interpretative simulations at a fixed radial position are combined with predictive JETTO simulations of temperatures and densities, using the TGLF transport model. The model includes electromagnetic effects and collisions as well as □(→┬E ) X □(→┬B ) shear in Miller geometry. Focus is on particle transport and the role of the neutral beam injection (NBI) particle source for the density peaking. The experimental 3-point collisionality scans include L-mode, and H-mode (D and H and higher beta D plasma) plasmas in a total of 12 discharges. Experimental results presented in (Tala et al 2017 44th EPS Conf.) indicate that for the H-mode scans, the NBI particle source plays an important role for the density peaking, whereas for the L-mode scan, the influence of the particle source is small. In general, both the interpretative and predictive transport simulations support the experimental conclusions on the role of the NBI particle source for the 12 JET discharges
Selective intra-graft apoptosis and down-regulation of lymphocyte bcl-2, iNOs and CD95L expression in kidney-pancreas transplanted patients after anti-Thymoglobulin induction
Intra-graft infiltrating cells apoptosis was evaluated in 20 consecutive kidney-pancreas transplanted (KP) patients without kidney rejection. Two fine-needle aspirated biopsy (FNAB) and two peripheral blood lymphocytes (PBL) samples were obtained 14 days after transplantation. Immunosuppression was based on anti-Thymoglobulins (ATG) induction for 7 days and cyclosporine/mofetil mycophenolate as maintenance therapy. Ten matched healthy subjects were chosen as controls for PBL. Lymphocyte phenotypes and activation markers, apoptotic rate and lymphocyte expression of pro/anti-apoptotic molecules were analysed by flow cytometry analysis (FACS). Lymphocyte phenotypes and activation markers: higher levels of CD8 and CD4DR were evident in the graft (p < 0.05) than in PBL, CD3CD25 in PBL were higher in transplanted patients than in controls. Apoptotic rate and lymphocyte expression of pro- and anti-apoptotic molecules: a higher expression of annexin V, together with reduced lymphocytes CD95L, iNOs and Bcl-2 expression (PBL = 97.7+/-1.1% vs FNAB = 81.9+/-15.1%; p < 0.05) were evident in the graft than in PBL. In KP patients intra-graft apoptosis and reduced anti-apoptotic molecules were evident after ATG induction

High Doses of Antimetabolites Followed by High-Dose Sequential Chemoimmunotherapy and Autologous Stem-Cell Transplantation in Patients With Systemic B-Cell Lymphoma and Secondary CNS Involvement : Final Results of a Multicenter Phase II Trial
PURPOSE:
Treatment of secondary CNS dissemination in patients with aggressive lymphomas remains an important, unmet clinical need. Herein, we report the final results of a multicenter phase II trial addressing a new treatment for secondary CNS lymphoma based on encouraging experiences with high doses of antimetabolites in primary CNS lymphoma and with rituximab plus high-dose sequential chemoimmunotherapy (R-HDS) in relapsed aggressive lymphoma.
PATIENTS AND METHODS:
HIV-negative patients with aggressive B-cell lymphoma and secondary CNS involvement at diagnosis or relapse, age 18 to 70 years, and Eastern Cooperative Oncology Group performance status 64 3 were enrolled and treated with high-doses of methotrexate and cytarabine, followed by R-HDS (cyclophosphamide, cytarabine, and etoposide) supported by autologous stem-cell transplantation (ASCT). Treatment included eight doses of rituximab and four doses of intrathecal liposomal cytarabine. The primary end point was 2-year event-free survival; the planned accrual was 38 patients.
RESULTS:
Thirty-eight patients were enrolled; CNS disease was detected at presentation in 16 patients. Toxicity was usually hematologic and manageable, with grade 4 febrile neutropenia in 3% of delivered courses and grade 4 nonhematologic toxicity in 2% of delivered courses. Four patients died because of toxicity. Autologous stem cells were successfully collected in 24 (89%) of 27 patients (median, 10
7 10(6)/kg); 20 patients underwent ASCT. Complete response was achieved in 24 patients (complete response rate, 63%; 95% CI, 48% to 78%). At a median follow-up of 48 months, 17 patients remained relapse free, with a 2-year event-free survival rate of 50% \ub1 8%. At 5 years, 16 patients were alive, with a 5-year overall survival rate of 41% \ub1 8% for the whole series and 68% \ub1 11% for patients who received transplantation. Systemic (extra-CNS) and/or meningeal disease did not affect outcome.
CONCLUSION:
The combination of high doses of antimetabolites, R-HDS, and ASCT is feasible and effective in patients age 18 to 70 years old with secondary CNS lymphoma, and we propose it as a new standard therapeutic option.

Clinical features, management and prognosis of multifocal primary bone lymphoma: a retrospective study of the international extranodal lymphoma study group (the IELSG 14 study).
'Multifocal bone lymphoma' or 'polyostotic lymphoma' is a neoplasm with exclusive multifocal involvement of the skeleton, without affecting lymph nodes or other soft tissues. Knowledge on this uncommon condition is limited because the related literature is sparse and fragmentary. We reviewed cases of multifocal bone diffuse large B-cell lymphoma (MB-DLBCL) registered in a clinico-pathological database of the International Extranodal Lymphoma Study Group that includes 499 cases of bone lymphoma. Clinical features, management and prognosis of 37 MB-DLBCL patients and 63 'controls' (stage-IV DLBCL and skeletal involvement) were analysed. Presentation and treatment of MB-DLBCL and controls were identical. At a median follow-up of 52 months (10-189), MB-DLBCL patients exhibited a significantly better response rate (92% vs. 65%; P = 0\ub7002), progression-free survival (5-year: 56 \ub1 9% vs. 34 \ub1 6%; P = 0\ub7003) and overall survival (5-year: 74 \ub1 8% vs. 36 \ub1 7%; P = 0\ub7002). Among MB-DLBCL patients, the use of post-chemo radiotherapy was associated with better overall survival (5-year: 83 \ub1 12% vs. 55 \ub1 16%; P = 0\ub7003). Two MB-DLBCL patients (5\ub74%) with spine and skull involvement experienced central nervous system (CNS) relapse. Thus, MB-DLBCL patients exhibit a significantly better prognosis compared to patients with advanced-stage DLBCL, and should be treated with conventional anthracycline-based chemotherapy, keeping intensified treatment for relapsing cases, considering involved-field radiotherapy, and CNS prophylaxis in high-risk patients
