The Regulatory Myeloid Cells - International Immunopharmacology Conference in October 21-24, 2010 reviewed the recent advances in our understanding of the biological mechanisms of expansion, activation, metabolism and mechanisms of T-cell suppression of myeloid derived suppressor cells (MDSC). Lectures were focused on the control of the microenvironment and cytokines needed for myelopoiesis, interactions with the neoplastic surrounding cells for a negative immune control and the role of MDSC in cancer promotion. The complexity of the tumor microenvironment and opportunities for therapeutic interventions by targeting, and/or manipulating MDSCs was emphasized. A better understanding of the crosstalk between myelo- and lymphoid arms of the immune system and of the metabolic alterations contributing to cancer phenotype provide new insights for the development of more efficient tumor immunotherapy strategies. This meeting report aims to provide the readers with a summary of the research highlights on human and mouse MDSCs presented in the meeting. © 2011 Landes Bioscience.

Haemorrhagic cystitis (HC) is a recognised complication in patients undergoing allogeneic haematopoietic stem cell transplantation (HSCT). This study evaluates the incidence and severity of HC in patients undergoing allogeneic HSCT during hospitalisation and within the first 100 days following transplant, looking at the use of prophylaxis, management of HC, outcomes at 100 days post transplant, and to identify any correlations between development of HC and the different conditioning regimens for transplant or HC prevention methods used. Results: Four hundred and fifty patients (412 adult and 38 paediatric) were enrolled in this prospective, multicentre, and observational study. HC was observed in 55 patients (12.2%) of which 8/38 were paediatric (21% of total paediatric sample) and 47/412 adults (11.4% of total adult sample). HC was observed primarily in the non-related HSCT group (45/55; 81.8%, p = 0.001) compared to sibling and myeloablative transplant protocols (48/55; 87.3%; p = 0.008) and with respect to reduced intensity conditioning regimens (7/55;12.7%). In 33 patients with HC (60%), BK virus was isolated in urine samples, a potential co-factor in the pathogenesis of HC. The median day of HC presentation was 23 days post HSCT infusion, with a mean duration of 20 days. The most frequent therapeutic treatments were placement of a bladder catheter (31/55; 56%) and continuous bladder irrigation (40/55; 73%). The range of variables in terms of conditioning regimens and so on, makes analysis difficult. Conclusions: This multi-centre national study reported similar incidence rates of HC to those in the literature. Evidence-based guidelines for prophylaxis and management are required in transplant centres. Further research is required to look at both prophylactic and therapeutic interventions, which also consider toxicity of newer conditioning regimens. © the authors; licensee ecancermedicalscience.

To evaluate trends in allografting from unrelated donors, we conducted a study on 196 consecutive myeloma patients transplanted between 2000 and 2009 in Italy. Twenty-eight percent, 37%, and 35%, respectively, received myeloablative, reduced-intensity, and nonmyeloablative conditioning. In these 3 cohorts, 1-year and 5-year transplantation-related mortalities were 28.8% and 37.0%, 20.3% and 31.3%, and 25.0% and 30.3%, respectively (. P = .745). Median overall survival (OS) and event-free survival from transplantation for the 3 cohorts were 29 and 10 months, 11 and 6 months, and 32 and 13 months, respectively (. P = .039 and P = .049). Overall cumulative incidences of acute and chronic graft-versus-host-disease (GVHD) were 46.1% and 51.1%. By Cox multivariate analyses, chronic GVHD was significantly associated with longer OS (hazard ratio [HR], .51; P = .009), whereas the use of peripheral blood stem cells was borderline significant (HR, .55; P = .051). Better response posttransplantation was associated with longer event-free survival (HR, 2.13 to 4.25; P < .001). Acute GVHD was associated with poorer OS (HR, 2.53; P = .001). This analysis showed a strong association of acute and chronic GVHD and depth of response posttransplantation with clinical outcomes. Long-term disease control remains challenging regardless of the conditioning. In the light of these results, prospective trials may be designed to better define the role of allografting from unrelated donors in myeloma. © 2013 American Society for Blood and Marrow Transplantation.

Purpose: Results of allogeneic stem-cell transplantation (allo) in myeloma are controversial. In this trial autologous stem-cell transplantation (auto) followed by reduced-intensity conditioning matched sibling donor allo (auto-allo) was compared with auto only in previously untreated multiple myeloma. Patients and Methods: In all, 357 patients with myeloma up to age 69 years were enrolled from 2001 to 2005. Patients with an HLA-identical sibling donor were allocated to the auto-allo arm (n = 108) and patients without a matched sibling donor were allocated to the auto arm (n = 249). Single (n = 145) or tandem (n = 104) auto was optional. Conditioning for the auto arm was melphalan 200 mg/m2; conditioning for the allo arm was total-body irradiation 2 Gy plus fludarabine 30 mg/m2/d for 3 days. Median follow-up time was 61 months. Primary end point was progression-free survival. Results: Progression-free survival at 60 months was significantly better with auto-allo than with allo alone (35% v 18%; P = .001), as was the risk of death and of relapse in the long term (P = .047 and P = .003, respectively). Overall survival at 60 months was 65% versus 58%, and relapse incidence was 49% versus 78%. Complete remission rates were 51% and 41%, respectively (P = .020). Nonrelapse mortality at 24 months was 12% after auto-allo compared with 3% in the auto group (P < .001). The incidence of grade 2 to 4 acute graft-versus-host disease (GvHD) was 20%, and the incidence of limited and extensive chronic GvHD was 31% and 23%. Conclusion: In patients with previously untreated multiple myeloma, long-term outcome with respect to progression-free survival, overall survival, and relapse rate is superior after auto-allo compared with auto only. Nonrelapse mortality is at a reasonable level in both groups. © 2011 by American Society of Clinical Oncology.

The purpose of this study was to assess the efficacy of cementoplasty in the treatment of sacral multiple myelomas. We retrospectively reviewed the records of eight patients (four women and four men; age range 47-68 years; mean age 57.8) who underwent cementoplasty for painful osteolytic localization of multiple myeloma between April 2007 and May 2009. The patients had difficulty walking because of increasing pain. Six patients had persistent pain despite other cementoplasties for vertebral and femoral localization, whereas two patients referred at the time of diagnosis had only sacral lesions. The clinical indication for treatment was (1) a pain intensity score ≥5 on visual analogue scale (VAS) and (2) pain totally or partially refractory to analgesic treatment in patients with a life expectancy >3 months. Technical planning was based on computed tomography and/or magnetic resonance imaging. Six patients had previously undergone radiotherapy or chemotherapy and were receiving varying doses of analgesics, whereas sacroplasty represented the first treatment for two patients. Five patients had monolateral local involvement, and the other patients had massive involvement of the sacrum; Technical success was achieved in all cases. We had only one small and asymptomatic foraminal leak. All patients experienced improvement in symptoms after the procedure, as demonstrated by improved VAS scores and performance status (PS) and decreased analgesic dose constant during follow-up. In our experience, percutaneous stabilization can be used effectively and safely in patients with focal or extensive involvement of the sacrum by multiple myeloma. © 2009 Springer Science+Business Media, LLC and the Cardiovascular and Interventional Radiological Society of Europe (CIRSE).
