Treatment of multiple myeloma patients with autologous stem cell transplantation — a fresh analysis

Patients with multiple myeloma (MM) treated with conventional chemotherapy have an average survival of approximately three years. High dose chemotherapy followed by autologous stem cell transplantation (ASCT), first introduced in the mid-1980s, is now considered the standard therapy for almost all patients with multiple myeloma, because it prolongs overall survival and disease free survival. Between November 1997 and October 2006, 122 patients with MM (58 females, 64 males, median age 51.0 years [± 7.98] range: 30–66 years) were transplanted in the Department of Hematooncology and Bone Marrow Transplantation at the Medical University of Lublin: 47 patients were in complete remission or in unconfirmed complete remission, 66 patients were in partial remission, and nine had stable disease. Of these, there were 95 patients with IgG myeloma, 16 with IgA myeloma, one with IgG/IgA, one with IgM myeloma, five with non secretory type, two with solitary tumor and two with LCD myeloma. According to Durie-Salmon, 62 patients had stage III of the disease, 46 had stage II and four had stage I. Most patients (69/122) were transplanted after two or more cycles of chemotherapy, 48 patients were transplanted after one cycle of chemotherapy, one patient after surgery and rtg- -therapy and four patients had not been treated. In mobilisation procedure, the patients received a single infusion of cyclophosphamide (4–6 g/m2) or etoposide 1.6 g/m2 followed by daily administration of G-CSF until the peripheral stem cells harvest. The number of median harvest sessions was 2.0 (± 0.89) (range: 1–5). An average of 7.09 (± 33.28) × 106 CD34+ cells/kg were collected from each patient (range: 1.8–111.0 × 106/kg). Conditioning regimen consisted of high dose melphalan 60–210 mg/m2 without TBI. An average of 3.04 (± 11.59) × 106 CD34+ cells/kg were transplanted to each patient. Fatal complications occured in four patients (treatment- -related mortality = 3.2%). In all patients there was regeneration of hematopoiesis. The median number of days for recovery to ANC > 0.5 × 109/l was 13 (± 4.69) (range: 10–38) and platelets recovery to > 50 × 109/l was 25 days (± 11.65) (range: 12–45). Median time of hospitalization was 22 days (± 7.14) (range: 14–50). Patients were evaluated on day 100 after transplantation: 74.9% achieved CR and nCR, 14.3% were in PR, 5.4% had SD and 5.4% had progressed. Median of OS was 45 months (± 30.67). OS at 3-years was 84% and at 7-years 59%. Median PFS was 25 months (± 26.13). PFS at 3-years was 68%, and at 7-years was 43%. At present (November 2009) 52 patients (42%) are still alive. High-dose chemotherapy followed by autologous stem cell transplantation is a valuable, well tolerated method of treatment for patients with MM that allows the achievement of long- -lasting survival.

Azimuthal anisotropy of charged jet production in root s(NN)=2.76 TeV Pb-Pb collisions

We present measurements of the azimuthal dependence of charged jet production in central and semi-central root s(NN) = 2.76 TeV Pb-Pb collisions with respect to the second harmonic event plane, quantified as nu(ch)(2) (jet). Jet finding is performed employing the anti-k(T) algorithm with a resolution parameter R = 0.2 using charged tracks from the ALICE tracking system. The contribution of the azimuthal anisotropy of the underlying event is taken into account event-by-event. The remaining (statistical) region-to-region fluctuations are removed on an ensemble basis by unfolding the jet spectra for different event plane orientations independently. Significant non-zero nu(ch)(2) (jet) is observed in semi-central collisions (30-50% centrality) for 20 <p(T)(ch) (jet) <90 GeV/c. The azimuthal dependence of the charged jet production is similar to the dependence observed for jets comprising both charged and neutral fragments, and compatible with measurements of the nu(2) of single charged particles at high p(T). Good agreement between the data and predictions from JEWEL, an event generator simulating parton shower evolution in the presence of a dense QCD medium, is found in semi-central collisions.

Production of He-4 and (4) in Pb-Pb collisions at root(NN)-N-S=2.76 TeV at the LHC

Results on the production of He-4 and (4) nuclei in Pb-Pb collisions at root(NN)-N-S = 2.76 TeV in the rapidity range vertical bar y vertical bar <1, using the ALICE detector, are presented in this paper. The rapidity densities corresponding to 0-10% central events are found to be dN/dy4(He) = (0.8 +/- 0.4 (stat) +/- 0.3 (syst)) x 10(-6) and dN/dy4 = (1.1 +/- 0.4 (stat) +/- 0.2 (syst)) x 10(-6), respectively. This is in agreement with the statistical thermal model expectation assuming the same chemical freeze-out temperature (T-chem = 156 MeV) as for light hadrons. The measured ratio of (4)/He-4 is 1.4 +/- 0.8 (stat) +/- 0.5 (syst). (C) 2018 Published by Elsevier B.V.Peer reviewe

Pseudorapidity and transverse-momentum distributions of charged particles in proton-proton collisions at root s=13 TeV

The pseudorapidity (eta) and transverse-momentum (p(T)) distributions of charged particles produced in proton-proton collisions are measured at the centre-of-mass energy root s = 13 TeV. The pseudorapidity distribution in vertical bar eta vertical bar <1.8 is reported for inelastic events and for events with at least one charged particle in vertical bar eta vertical bar <1. The pseudorapidity density of charged particles produced in the pseudorapidity region vertical bar eta vertical bar <0.5 is 5.31 +/- 0.18 and 6.46 +/- 0.19 for the two event classes, respectively. The transverse-momentum distribution of charged particles is measured in the range 0.15 <p(T) <20 GeV/c and vertical bar eta vertical bar <0.8 for events with at least one charged particle in vertical bar eta vertical bar <1. The evolution of the transverse momentum spectra of charged particles is also investigated as a function of event multiplicity. The results are compared with calculations from PYTHIA and EPOS Monte Carlo generators. (C) 2015 CERN for the benefit of the ALICE Collaboration. Published by Elsevier B.V.
