In this study, reactivation of the varicella zoster virus (VZV) developed in 57 (30%) of 191 patients with myeloma. The VZV reactivation occurred during the induction chemotherapy (8.5% of patients), or after the autologous stem cell transplant (ASCT) (21.5% of patients). Interestingly, for unclear reasons, there was an association between the VZV reactivation after the ASCT and a better median overall survival ("not reached" vs 87 months). Patients received acyclovir 400 mg twice a day for 3 weeks after the ASCT. The incidence of VZV reactivation after the ASCT was about 10% at 1 year, about 15% at 2 years, and about 20% at 4 years.

This study reviews incidence of second cancers among 4161 patients with multiple myeloma treated with an autologous stem cell transplant. Follow-up identified 163 cases of new cancers, with a cumulative incidence of 6.1% at 7 years after transplant. The incidence of new cancers in these patients was similar to that in matched U.S. population, with the exception of AML and melanoma, which were more frequent. Multivariate analysis showed that factors associated to an increased risk of second cancers were obesity, older age, and male gender.

APOBEC family mutational signatures are associated with poor prognosis translocations in multiple myeloma.

Walker BA, Wardell CP, Murison A, Boyle EM, Begum DB, Dahir NM, Proszek PZ, Melchor L, Pawlyn C, Kaiser MF, Johnson DC, Qiang YW, Jones JR, Cairns DA, Gregory WM, Owen RG, Cook G, Drayson MT, Jackson GH, Davies FE, Morgan GJ.
The authors did whole exomic sequence of 463 cases of newly diagnosed multiple myeloma. They found an APOBEC mutational signature in 4% of cases. They were associated to the translocations t(14;16) and t(14;20), which result in deregulation of the MAF and MAFB genes, respectively. APOBEC is a family of enzymes editing the DNA, and they deaminate cytosine to uracil in single-stranded DNA.
  - In MAF and MAFB, the mutations were only seen in the basic-leucine zipper domain
  - In FGFR3, the mutations were scattered throughout the gene

Phase I/II study of the combination of panobinostat and carfilzomib in patients with relapsed/refractory multiple myeloma.
Haematologica. 2015 May;100(5):670-6.
Berdeja JG, Hart LL, Mace JR, Arrowsmith ER, Essell JH, Owera RS, Hainsworth JD, Flinn IW.
In this study, 44 patients with myeloma relapsed after at least one line of therapy were treated with carfilzomib + panobinostat. Optimal doses were 20/45 mg/m2 for carfilzomib, and 30 mg for panobinostat. The response rate was 67% for all patients. At a median follow up of 17 months, median overall survival was not reached, and median progression-free survival was 8 months.

Features of extramedullary disease of multiple myeloma: high frequency of p53 deletion and poor survival: a retrospective single-center study of 834 cases.
Clin Lymphoma Myeloma Leuk. 2015 May;15(5):286-91.
Deng S, Xu Y, An G, Sui W, Zou D, Zhao Y, Qi J, Li F, Hao M, Qiu L.
Among 834 consecutive MM patients in a single center in China, extrameduallary disease was found in 4.8% of cases at the time of diagnosis, and in 3.4% during the course of the disease. Patients with extrameduallary disease had a higher prevalence of p53 deletion at FISH (35% vs. 12%), worse time to progression (12 vs 25 months), and worse median survival (16.5 vs 40 months). At multivariate analysis, the presence of EMD remained an independent adverse prognostic factor.

Phase 1/2 study of carfilzomib plus melphalan and prednisone in patients aged over 65 years with newly diagnosed multiple myeloma.

CMP (carfilzomib, melphalan, and prednisone) was administered for up to 9 cycles to 66 elderly patients with newly diagnosed myeloma (24 patients for phase 1 and 44 patients for phase 2). The MTD for carfilzomib was established as 36 mg/m2. Among 50 evaluable patients, the response rate was 90%, and the projected 3-year overall survival rate was 80%.

Comparison of upfront tandem autologous-allogeneic transplantation versus reduced intensity allogeneic transplantation for multiple myeloma.
Bone Marrow Transplant. 2015 Jun;50(6):802-7.

This is a retrospective study comparing the outcomes of an early reduced intensity conditioning (RIC) allogeneic transplant (173 patients) vs tandem autologous-allogeneic transplant (517 patients). After a median follow-up of about 8 years, results favored the planned tandem auto-allo transplants:
   - 5-year progression-free survival: 22% in the allo group, and 34% in the auto-allo group (p<0.001)
   - 5-year overall survival: 42% in the allo group, and 59% in the auto-allo group (p<0.001)

Autologous stem cell transplantation versus novel drugs or conventional chemotherapy for patients with relapsed multiple myeloma after previous ASCT.

This is a retrospective analysis of outcomes between salvage therapies in patiuents with multiple myeloma in relapse after they already received a first autologous stem cell transplant. A second autologous transplant was performed in 111 patients, whereas other patients were treated with novel agents, including proteasome inhibitors and IMiDs (362 patients), or traditional chemotherapy (91 patients). The results favored the second autologous transplant, because the median survival was 4 years with the second autologous transplant, 3.3 years with the novel agents, and 2.5 years with the conventional chemotherapy drugs.

This study questions the use of cyclophosphamide as mobilization strategy for collecting stem cells in patients with multiple myeloma, because it increased toxicity and it did not improve long-term outcomes. Patients underwent stem cell collection with either G-CSF alone (73 patients) or cyclophosphamide + G-CSF (94 patients). Results:
  - Total CD34 cells/Kg collected: 5.8 million with C-CSF vs 12 million with cyclophosphamide + G-CSF
  - Hospitalizations due to complications: 0% with G-CSF vs 14% with cyclophosphamide + G-CSF
  - Overall survival was similar in the two groups
