Outcome and characteristics of nonsecretory multiple myeloma compared with secretory multiple myeloma: a retrospective multicenter study from China. BMC Cancer 2023; 23:930. [PMID: 37784037 PMCID: PMC10546718 DOI: 10.1186/s12885-023-11223-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2022] [Accepted: 07/25/2023] [Indexed: 10/04/2023] Open
Abstract
BACKGROUND Nonsecretory multiple myeloma (NSMM) is a rare type of multiple myeloma (MM). Few studies have described the clinical features and outcomes of NSMM in novel agents. Additionally, the prognostic characteristics have remained controversial in recent years. PURPOSE To investigate the clinical and prognostic features of NSMM and explore the prognostic value of involved free light chain (FLC) levels in NSMM patients in the Chinese population. METHODS We retrospectively enrolled 176 newly diagnosed NSMM cases between January 2005 and December 2021 from 19 clinical centers in China. The control group was selected using a 1:4 propensity score matching technique of newly diagnosed secretory MM, with age, sex and diagnosis time as the matching variables. RESULTS The median age of NSMM patients was 60 years, and 22.6% of patients were classified as ISS stage 3. The ORR of the NSMM patients was 87.4%, and the CR was 65.8%. Compared to the matched secretory MM patients, more NSMM patients achieved CR after first-line treatment (65.8% vs. 36%, p = 0.000). The ORR of first-line treatment was not significantly different between NSMM and secretory MM (89.45% vs. 84.7%, p = 0.196). The first-line PFS was 27.5 m and 23 m (p = 0.063), and the median OS was 81 m and 70 months (p = 0.401). However, for CR-achieved NSMM and CR-not-achieved NSMM patients, the median PFS was 37 m vs. 16 m (p = 0.021), while the median OS showed no difference (107 m vs. 87 m, p = 0.290). In multivariate analysis, the significant factors for PFS were age ≥ 65 and ISS-3. ISS-3 was the only independent prognostic factor of OS. The iFLC ≥ 50 mg/L group had a high ORR of 97.3%, and the median PFS and OS were 48 m and NR, respectively. Compared to the matched secretory MM, the iFLC ≥ 50 mg/L group also showed more CR and longer OS (NR vs. 70 m, p = 0.006) and PFS (48 m vs. 23 m, p = 0.003). CONCLUSIONS Our results revealed that Chinese NSMM patients are younger and have a higher CR but not superior survival. The subgroup of NSMM patients with iFLC ≥ 50 mg/L had better outcomes than secretory MM.

Mobilization Strategies in Myeloma Patients Intended for Autologous Hematopoietic Cell Transplantation. Transfus Med Hemother 2023; 50:438-447. [PMID: 37899993 PMCID: PMC10603622 DOI: 10.1159/000531940] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2022] [Accepted: 06/21/2023] [Indexed: 10/31/2023] Open
Abstract
Background Multiple myeloma is currently the leading indication for autologous hematopoietic cell transplantation (AHCT). A prerequisite for AHCT is mobilization and collection of adequate blood graft to support high-dose therapy. Current mobilization strategies include granulocyte colony-stimulating factor (G-CSF) alone or in combination with chemotherapy most commonly cyclophosphamide (CY). More recently, plerixafor has become into agenda especially in patients who mobilize poorly. In the selection of a mobilization method, several factors should be considered. Summary Preplanned collection target is important as G-CSF plus plerixafor is more effective in the mobilization of CD34+ cells than G-CSF alone. On the other hand, CY plus G-CSF is superior to G-CSF only mobilization. Previous therapy and age of the patients are important considerations as G-CSF alone may not be effective enough in patients with risk factors for poor mobilization. These factors include extensive lenalidomide exposure, irradiation to bone marrow-bearing sites, higher age, or a previous mobilization failure. Also, local preferences and experiences as well as the number of apheresis needed are important issues as well as cost-effectiveness considerations. Mobilization method used may have implication for cellular composition of collected grafts, which might have an impact on posttransplant events such as hematologic and immune recovery in addition to also potential long-term outcomes. Key Message Currently, G-CSF alone and preemptive plerixafor if needed might be considered as a standard mobilization strategy in MM patients intended for AHCT.

Impact of interval progression before autologous stem cell transplant in patients with multiple myeloma. Front Oncol 2023; 13:1216461. [PMID: 37554170 PMCID: PMC10405820 DOI: 10.3389/fonc.2023.1216461] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2023] [Accepted: 06/28/2023] [Indexed: 08/10/2023] Open
Abstract
In transplant-eligible patients who undergo upfront autologous stem cell transplant (ASCT) for multiple myeloma (MM), standard practice is to treat with six to eight cycles of induction therapy followed by high-dose chemotherapy with ASCT. A gap between the end of induction and the day of ASCT exists to allow stem cell mobilization and collection. Despite attempts to limit the length of this interval, we noticed that some patients experience interval progression (IP) of disease between the end of induction therapy and the day of ASCT. We analyzed 408 MM patients who underwent ASCT between 2011 and 2016. The median length of the interval between end of induction and ASCT was 38 days. We observed that 26% of patients in the entire cohort and 23.6% of patients who received induction with bortezomib-lenalidomide-dexamethasone (VRD) experienced IP. These patients deepened their responses with ASCT, independently of induction regimen. In the entire cohort, IP was significantly associated with shorter PFS in the univariable analysis (Hazard Ratio, HR = 1.37, P = 0.022) but not in the multivariable analysis (HR = 1.14, P = 0.44). However, analyzing only patients who received VRD as induction, progression-free survival (PFS) remained inferior in both the univariable (HR = 2.02; P = 0.002) and the multivariable analyses (HR = 1.96; P = 0.01). T cells and natural killer (NK) cells are increasingly studied targets of immunomodulatory therapy, as immune dysfunction is known to occur in patients with MM. Peripheral blood from 35 MM patients were analyzed. At time of ASCT, patients with IP had significantly increased percentages of CD3+CD8+CD57+ CD28- (P = 0.05) and CD3+CD4+LAG3+ (P = 0.0022) T-cells, as well as less CD56bright and CD56dim NK cells bearing activated markers such as CD69, NKG2D, and CD226. These data suggest that IP can impact the length of response to ASCT; therefore, further studies on the management of these patients are needed.

Comparison of clinical and laboratory characteristics of nonsecretory multiple myeloma and secretory multiple myeloma in a tertiary care hospital. Int J Lab Hematol 2022; 44:582-588. [PMID: 35218612 DOI: 10.1111/ijlh.13811] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2021] [Revised: 01/15/2022] [Accepted: 01/29/2022] [Indexed: 11/30/2022]
Abstract
INTRODUCTION Nonsecretory multiple myeloma (NSM) is a rare variant of multiple myeloma, accounting for approximately 1%-5% of all reported cases. We compared the characteristics of NSM and secretory multiple myeloma (SM). METHODS We examined clinical and laboratory characteristics of 17 patients diagnosed with NSM and 40 patients diagnosed with SM. NSM was diagnosed based on findings of bone marrow (BM) examination, serum-free light chain (sFLC) assay, flow cytometric (FCM) immunophenotyping, chromosomal analysis, and imaging studies. RESULTS No patient with NSM had hypercalcemia or renal insufficiency at diagnosis. Patients with NSM were less anemic (p < .05) but had higher lactate dehydrogenase levels (p < .05) than patients with SM. In addition, patients with NSM had a lower percentage of plasma cells in the BM, confirmed by manual differential count (p < .05) and FCM immunophenotyping (p < .05). The sFLC ratio in patients with NSM was abnormal (15/17, 88.2%) and was lower than that in patients with SM (p < .05). Risk stratification in Revised International Staging System revealed a low-risk tendency in patients with NSM (p = .235). CONCLUSION NSM patients showed different clinical and laboratory characteristics from SM patients. FCM immunophenotyping and sFLC assay particularly had differences between NSM patients and SM patients. Thus, they are essential for diagnosing NSM.

Abstract
La chimiothérapie à haute dose suivie d´autogreffe des cellules souches hématopoïétiques (ASCT) reste le traitement de choix du myélome multiple chez les sujets âgés ≤ 65 ans. Dans les pays en développement, l´ASCT sans cryoconservation, permet de réduire les coûts d´hospitalisation et des installations nécessaires. Pour évaluer cette procédure, une étude prospective, longitudinale et ouverte a été conduite au Service d´Hématologie Clinique de Casablanca au Maroc. Sur 24 mois, 64 patients ont été colligés. Après le traitement d´induction, la réponse globale (Rémission complète + Très bonne réponse partielle) était à 67,2% (43 patients). La richesse moyenne du greffon autologue était de 12.97x106 CD34+/Kg [2.4- 53x106 CD34+/Kg] et la durée médiane d´hospitalisation était de 20,5 jours [14-60 jours]. La réponse globale en post autogreffe était de 84% (54 patients). A 24 mois, l´estimation de la survie globale (OS) était à 83,5%, la médiane d´OS n´était pas atteinte et la survie sans progression (PFS) à 65,9% avec une médiane de la PFS à 24,1 mois avec un intervalle de confiance à 95% [21,7-26,5mois]. L´ASCT sans cryoconservation reste une excellente alternative dans notre contexte, ce qui permet de réduire les délais d´attente, et les coûts de congélation.

The Effect of Cryotherapy on the Prevention of Oral Mucositis and on the Oral pH Value in Multiple Myeloma Patients Undergoing Autologous Stem Cell Transplantation. Semin Oncol Nurs 2021; 37:151146. [PMID: 34001407 DOI: 10.1016/j.soncn.2021.151146] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2020] [Revised: 02/19/2021] [Accepted: 03/11/2021] [Indexed: 11/24/2022]
Abstract
OBJECTIVE The aim of this study was to evaluate the effectiveness of cryotherapy on the prevention of oral mucositis (OM) and on the oral pH value in patients with multiple myeloma undergoing autologous stem cell transplantation. DATA SOURCES This nonrandomized controlled clinical trial was carried out in Bone Marrow Transplant Centers of three hospitals with total 32 patients. In addition to standard oral care, a total of 80 minutes of cryotherapy was applied to the experimental group. OM was assessed according to the World Health Organization's Oral Toxicity Scale before chemotherapy and for 21 days after chemotherapy (every day in the first 14 days, then every other day until the 21st day [if not discharged]). CONCLUSION According to the findings, cryotherapy did not change the incidence of oral OM, and neither affected the severity of nor decreased the duration of it. Oral pH value was found to be significantly different between the patient groups only before and 1 day after chemotherapy. IMPLICATIONS FOR NURSING PRACTICE Cryotherapy is an inexpensive, easy-to-use method with no side effects; it would be beneficial to continue cryotherapy to prevent the development of OM in patients with cancer receiving drugs with a short half-life such as melphalan. It is also recommended to conduct further studies with different chemotherapy drugs with short half-lives to determine its effect on the prevention of OM development.

IgD Subtype But Not IgM or Non-Secretory Is a Prognostic Marker for Poor Survival Following Autologous Hematopoietic Cell Transplantation in Multiple Myeloma. Results From the EBMT CALM (Collaboration to Collect Autologous Transplant Outcomes in Lymphomas and Myeloma) Study. CLINICAL LYMPHOMA MYELOMA & LEUKEMIA 2021; 21:686-693. [PMID: 34158265 DOI: 10.1016/j.clml.2021.05.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/22/2021] [Revised: 05/12/2021] [Accepted: 05/16/2021] [Indexed: 10/21/2022]
Abstract
BACKGROUND The Collaboration to Collect Autologous Transplant Outcomes in Lymphoma and Myeloma (CALM) study has provided an opportunity to evaluate the real-world outcomes of patients with myeloma. The aim of this study was to compare the outcome according to the different subtypes of myeloma using CALM data. PATIENTS This study compared overall survival (OS), progression-free survival (PFS), and complete remission (CR) and the impact of novel versus non-novel drug containing induction regimens prior to autologous hematopoietic cell transplantation (HCT) of 2802 patients with "usual" and "rare" myelomas. RESULTS Our data suggest that IgM and non-secretory myeloma have superior PFS and OS compared with IgD myeloma and outcomes comparable to those for usual myeloma. Patients who received novel agent induction had higher rates of CR prior to transplant. Non-novel induction regimens were associated with inferior PFS but no difference in OS. Although not the primary focus of this study, we show that poor mobilization status is associated with reduced PFS and OS, but these differences disappear in multivariate analysis suggesting that poor mobilization status is a surrogate for other indicators of poor prognosis. CONCLUSION We confirm that IgD myeloma is associated with the worst prognosis and inferior outcomes compared with the other isotypes.

Abstract
BACKGROUND Autologous stem cell transplantation (auto-SCT) is a widely used treatment option in multiple myeloma (MM) patients. The optimal graft cellular composition is not known. STUDY DESIGN AND METHODS Autograft cellular composition was analyzed after freezing by flow cytometry in 127 MM patients participating in a prospective multicenter study. The impact of graft cellular composition on hematologic recovery and outcome after auto-SCT was evaluated. RESULTS A higher graft CD34+ cell content predicted faster platelet recovery after auto-SCT in both the short and long term. In patients with standard-risk cytogenetics, a higher graft CD34+ count (>2.5 × 106 /kg) was linked with shorter progression-free survival (PFS; 28 vs. 46 months, p = 0.04), but there was no difference in overall survival (OS) (p = 0.53). In a multivariate model, a higher graft CD34+ CD133+ CD38- (>0.065 × 106 /kg, p = 0.009) and NK cell count (>2.5 × 106 /kg, p = 0.026), lenalidomide maintenance and standard-risk cytogenetics predicted better PFS. In contrast, a higher CD34+ count (>2.5 × 106 /kg, p = 0.015) predicted worse PFS. A very low CD3+ cell count (≤20 × 106 /kg, p = 0.001) in the infused graft and high-risk cytogenetics remained predictive of worse OS. CONCLUSIONS Autograft cellular composition may impact outcome in MM patients after auto-SCT. More studies are needed to define optimal graft composition.

Age Is a Prognostic Factor for the Overall Survival of Patients with Multiple Myeloma Undergoing Upfront Autologous Hematopoietic Stem Cell Transplantation. Biol Blood Marrow Transplant 2019; 26:1077-1083.

Abstract
In this retrospective analysis, we evaluated the impact of age on the outcome of patients with multiple myeloma who received an autologous hematopoietic stem cell transplantation (auto-HCT) at our institution. A total of 1128 patients were divided into the older (>70 years; 182 [16%]) and the younger (≤70 years; 946 [84%]) groups. Compared with the younger cohort, older patients had a higher International Staging System (ISS) stage (ISS-II, 57 [31%] versus 215 [23%]; ISS-III, 52 [28%] versus 211 [22%]; P = .01), higher use of reduced-dose melphalan as a conditioning regimen (140 mg/m², 59 [32%] versus 29 [3%]; P < .001), and a higher comorbidity index (median, 3 versus 2; P = .01). Nonrelapse mortality at 1 year after auto-HCT was significantly higher in older patients (7 [4%] versus 9 [1%]; hazard ratio [HR], 4.1; P = .005). Complete remission rates after auto-HCT for the older and the younger groups were 41% and 46%, respectively. With a median follow-up of 52 months, the 5-year progression-free survival (PFS) was 24% (95% confidence interval [CI], 17% to 32%) and 37% (95% CI, 33% to 40%) in the older and younger groups, respectively (HR, 1.3; P = .02). Five-year OS for the older and younger groups was 56% (95% CI, 47% to 64%) and 73% (95% CI, 70% to 76%; P < .001), respectively. Older age emerged as one of the predictors of shorter OS but not PFS in the multivariate classification and regression tree analysis. In conclusion, age ≥70 years was associated with shorter PFS and OS in patients with multiple myeloma who underwent an auto-HCT.

Abstract
BACKGROUND Non-secretory multiple myeloma (NSMM) is a rare subtype of multiple myeloma (MM) characterized by the absence of monoclonal protein in the serum and/or urine. We look at the clinical and cytogenetic features of NSMM in this study. PATIENTS AND METHODS This study evaluates a cohort of 30 patients with newly diagnosed NSMM seen at the Mayo Clinic, Rochester, MN, between 2008 and 2018 and treated with novel agent induction therapies. Survival outcomes were estimated using the Kaplan-Meier method and compared using the log-rank test. RESULTS These patients with NSMM appear to have a large disease burden at diagnosis with a median bone marrow plasma cell percentage of 70% and more than one-half of all patients having Multiple Myeloma International Staging System Stage III disease. There was a higher preponderance for t(11;14) primary cytogenetic abnormality in this NSMM cohort, accounting for more than 50% of the cohort. Finally, the overall survival of this cohort appears to be slightly worse than a matched-control group of newly diagnosed patients with MM with secretory disease. CONCLUSIONS Future multi-institution studies confirming these above findings on this rare entity are warranted.

Non-Secretory Myeloma: Ready for a new Definition? Mediterr J Hematol Infect Dis 2017; 9:e2017053.

Abstract
Non-secretory myeloma is a rare myeloma subtype whose diagnosis, until a few years ago, was established by demonstration of monoclonal plasma cells ≥10% in the bone marrow and by negative results on serum and urine electrophoresis and immunofixation studies. However, this type of myeloma could be misdiagnosed if the workup does not include an accurate study of serum free light chain test since some of the patients diagnosed as non-secretory could be light chain only with small amounts monoclonal proteinuria. Due to this limit in classification, all the information available today, generally coming from retrospective studies including patients studied completely and incompletely, could be misleading. A new definition is, thus, needed to distinguish between the true non-secretory, with a possible better prognosis, and the other forms of oligo-secretory myeloma with a prognosis more similar to the secretory form of myeloma. With all the data of the literature, the availability of laboratory and radiological tools, times are mature to depict a new definition of nonsecretory myeloma that deserves a peculiar work up and different response evaluation and, may be, a different therapeutic approach.

Abstract
OBJECTIVE To review disease-related symptoms and side effects of treatment in patients with multiple myeloma (MM). DATA SOURCES Peer-reviewed articles, research studies, and clinical guidelines. CONCLUSION New therapies provide patients with extended survival, but in many cases this benefit is counterbalanced by an increased incidence of side effects. Preservation of organ function, while managing side effects, is essential for the care of patients with MM. IMPLICATIONS FOR NURSING PRACTICE Disease- and treatment-related adverse events are prevalent in patients with MM. Patient, family, and health care professional education is essential to monitor and manage these side effects.

Abstract
BACKGROUND AND OBJECTIVES Since a study published in 2002 showed a survival advantage of melphalan-only conditioning for stem cell transplantation (HSCT) over melphalan-total body irradiation (mel-TBI) in patients with multiple myeloma (MM), most centers abandoned mel-TBI. Mel-TBI causes more early toxicity and is more complicated to administer, but we speculated it may result in longer term survival with radiation as an independent treatment modality. Therefore, we analyzed the long-term outcome of patients with MM who received mel-TBI as part of conditioning at our center. PATIENTS AND METHODS From 1995 to 2013, 50 patients with MM underwent autologous HSCT at Tulane University Medical Center using mel-TBI conditioning. We used Kaplan-Meier survival analysis and compared our patients with data available from the Louisiana Tumor Registry. RESULTS The mean survival of our patients was 70.98 months from time of transplant and 84.2 months from time of initial diagnosis. No differences were observed according to gender, ethnicity, or age at transplant. The expected median survival in a population-based registry (matched for age and year of treatment) was 27 months (P<.001). CONCLUSIONS Total body irradiation in conjunction with melphalan as conditioning is feasible and can lead to long-term survival. More research is necessary to determine which patients benefit most. Mel-TBI should also be explored in conjunction with immunotherapy.

Impact of Hepatitis B Core Antibody Seropositivity on the Outcome of Autologous Hematopoietic Stem Cell Transplantation for Multiple Myeloma. Biol Blood Marrow Transplant 2017; 23:581-587.

Abstract
Hepatitis B core antibody (HBcAb) seropositivity has been associated with a higher rate of hepatitis B virus (HBV) reactivation after chemotherapy, even in patients who are hepatitis B surface antigen (HBsAg) negative. However, little is known about the risk of HBV reactivation after autologous hematopoietic stem cell transplantation (auto-HCT). We evaluated the incidence of HBV reactivation, liver toxicity, and survival in patients with multiple myeloma (MM) who received auto-HCT at our institution. We retrospectively identified 107 MM patients with resolved HBV infection (HBcAb positive, HBsAg negative) and 125 patients with negative HBV serology (control subjects) who were matched for age, timing of auto-HCT from diagnosis, cytogenetics, disease status at transplant, induction therapy, and preparative regimen. All patients underwent auto-HCT between 1991 and 2013. Primary endpoints were HBV reactivation, defined as HBsAg positivity or ≥10-fold increase in HBV DNA, and hepatotoxicity, as defined in the U.S. National Cancer Institute Common Terminology Criteria for Adverse Events v3.0. In the resolved HBV infection group, 52 patients (49%) were HBsAb positive and 24 (22%) had detectable HBV DNA before auto-HCT. Only 1 patient with resolved HBV infection received pre-emptive antiviral therapy with lamivudine, whereas 4 patients received lamivudine (n = 3) or tenofovir (n = 1) at reactivation after auto-HCT for a median duration of 12 months. HBV reactivation occurred in 7 of 107 patients (6.5%) in the resolved HBV group. Median time to HBV reactivation from auto-HCT was 16 months. The cumulative incidence of grade 2 or greater hepatotoxicity was 30% in the resolved HBV infection group and 22% in the control group (hazard ratio, 1.3; 95% confidence interval, .7 to 2.3; P = .4). Nonrelapse mortality for the 2 groups was not statistically different at 2 years (P = .06), although it trended higher in the control group than in the resolved HBV infection group (8% versus 1%). The median progression-free survival (PFS) and overall survival (OS) durations in the resolved HBV infection and control groups were 21 versus 18 months (P = .5) and 53 versus 67 months (P = .2), respectively. Our data suggest that resolved HBV infection in patients undergoing auto-HCT for MM is associated with a low risk of HBV reactivation and hepatotoxicity; these complications were reversible and did not adversely affect the PFS or OS.

Abstract
Multiple myeloma (MM) is the second most common hematologic malignancy in the US. It is typically characterized by production of large amounts of defective immunoglobulin (Ig). Diagnosing MM and monitoring treatment response, including eventual relapse, are largely based on sequential measurements of Ig. However, a small subset of MM called non-secretory multiple myeloma (NSMM) produces no detectable Ig. This subset of true NSMM has become even smaller over time, as the advent of the serum free light chain assay has resulted in the majority of NSMM patients being recategorized as light-chain MM – that is, MM cells that produce only the light-chain component of Ig. True forms of NSMM, meaning MM that secretes no monoclonal proteins whatsoever, constitute a distinct entity that is reviewed; definition of NSMM using current detection methods, discuss the biology underpinning NSMM development, and share recommendations for how NSMM should be managed clinically with respect to detection, treatment, and monitoring.

Abstract
Randomized trials showing that high-dose therapy with autologous stem cell transplant (ASCT) improved the overall survival (OS) in multiple myeloma (MM) excluded patients over age 65. To compare the outcomes of older adults with MM who underwent ASCT with non-transplant strategies, we identified 146 patients aged 65-77 with newly diagnosed MM seen in the Washington University School of Medicine from 2000 to 2010. Survival among patients who did (N=62) versus did not (N=84) undergo ASCT was compared using Cox proportional hazards modeling, controlling for comorbidities, Eastern Cooperative Oncology Group performance status (PS) and the propensity to undergo ASCT. Median age was 68 years (range 65-77). PS and comorbidities did not differ significantly between those who did versus those who did not undergo ASCT. Median OS was significantly longer in patients who underwent ASCT than in those who did not (median 56.0 months (95% confidence intervals (CIs) 49.1-65.4) versus 33.1 months (24.3-43.1), P=0.004). Adjusting for PS, comorbidities, Durie-Salmon stage and the propensity to undergo ASCT, ASCT was associated with superior OS (HR for mortality 0.52 (95% CI 0.30-0.91), P=0.02). In a cohort of older adults with MM, undergoing ASCT was associated with a nearly 50% lower mortality, after controlling for PS, comorbidities, stage and the propensity to undergo ASCT.

Abstract
OBJECTIVE To determine the prognosis of patients with non-secretory myeloma. METHODS We studied 124 patients diagnosed with multiple myeloma who had no monoclonal protein detected on serum and urine immunofixation at diagnosis and on all subsequent follow-up testing (non-secretory myeloma). The overall survival (OS) of patients with non-secretory myeloma was compared with 6953 patients with typical myeloma seen during the same time period in whom a monoclonal protein was detected at the time of diagnosis. RESULTS One hundred and twenty-four patients met criteria for non-secretory multiple myeloma. The median follow-up was 102 months (range, 1-204 months). The median progression-free survival with initial therapy was 28.6 months, and the median OS was 49.3 months. There was a significant improvement in OS since 2001; median survival 43.8 months (prior to 2001) vs. 99.2 months (2001-2012), P < 0.001. OS was superior in patients with a normal baseline FLC ratio (n = 10) compared to patients with an abnormal ratio (n = 19), medians not reached in both groups. Prior to 2001, OS was similar in non-secretory myeloma (n = 86) and secretory myeloma (n = 4011), median 3.6 vs. 3.5 yr, respectively, P = 0.63. However, among patients diagnosed between 2001 and 2012, OS was superior in non-secretory myeloma (n = 36) compared to secretory myeloma (n = 2942), median 8.3 vs. 5.4 yr, respectively, P = 0.03. CONCLUSIONS Non-secretory myeloma is an uncommon subtype of multiple myeloma. In the last decade, there has been an improvement in the survival of non-secretory myeloma and appears superior to secretory myeloma.

Abstract
PURPOSE Multiple myeloma (MM) is disproportionately diagnosed in older adults; with the aging of the population, the number of older adults diagnosed with MM will increase by nearly 80% in the next two decades. Duration of survival has improved dramatically over the last 20 years, but the improvements in older adults have not been as great as those in younger adults with MM. METHODS In this article, we address treatment approaches in older adults who are eligible for and those ineligible for high-dose therapy with autologous stem-cell transplantation as well as supportive care considerations and the potential role for geriatric assessment in facilitating decision making for older adults with MM. RESULTS The evidence from recent studies demonstrates that combinations of novel and conventional antimyeloma agents result in improved response rates and, in some cases, improved progression-free and overall survival. However, some older adults are particularly vulnerable to toxicities of therapy and discontinuation of therapy and, consequently, they have poorer survival. In addition, older adults may prioritize other outcomes of therapy, such as quality of life, over more conventional end points such as disease response and duration of survival. Geriatric assessment can facilitate risk-stratification of older adults at greater risk for adverse events from therapy and aid in personalizing therapy for vulnerable or frail older adults. CONCLUSION Survival in older adults with MM is improving with novel therapeutics, but efficacy must be balanced with risk of toxicity of therapy and maintenance of quality of life. Novel instruments such as geriatric assessment tools may facilitate these aims.

Abstract
Bisphosphonates are currently the standard approach to managing bone disease in multiple myeloma. Bisphosphonates have high bone affinity that inhibits osteoclastic activity and additionally reduces the growth factors released from malignant or osteoblastic cells, thereby impairing abnormal bone remodeling which leads to osteolysis. However, patients of multiple myeloma may be at a higher risk of atypical femoral fractures because the treatment for malignant myeloma requires notably higher cumulative doses of bisphosphonates. Here we present a patient with bilateral atypical femoral fractures and multiple myeloma treated with intravenous bisphosphonate therapy.

Abstract
Autologous hematopoietic cell transplantation (AHCT) for plasma cell myeloma is performed less often in people >70 years old than in people ≤70 years old. We analyzed 11,430 AHCT recipients for plasma cell myeloma prospectively reported to the Center for International Blood and Marrow Transplant Research between 2008 and 2011, representing the majority of US AHCT activity during this period. Survival (OS) was compared in 3 cohorts: ages 18 to 59 years (n = 5818), 60 to 69 years (n = 4666), and >70 years (n = 946). Median OS was not reached for any cohort. In multivariate analysis, increasing age was associated with mortality (P = .0006). Myeloma-specific mortality was similar among cohorts at 12%, indicating an age-related effect on nonmyeloma mortality. Analyses were performed in a representative subgroup comparing relapse rate, progression-free survival (PFS), and nonrelapse mortality (NRM). One-year NRM was 0% for age >70 years and 2% for other ages (P = not significant). The three-year relapse rate was 56% in age 18 to 59 years, 61% in age 60 to 69 years, and 63% age >70 (P = not significant). Three-year PFS was similar at 42% in age 18 to 59 years, 38% in age 60 to 69 years, and 33% in age >70 years (P = not significant). Postrelapse survival was significantly worse for the older cohort (P = .03). Older subjects selected for AHCT derived similar antimyeloma benefit without worse NRM, relapse rate, or PFS.

Abstract
BACKGROUND AND OBJECTIVE The optimal treatment of patients with multiple myeloma (MM) is not well defined, in part because these patients are underrepresented in clinical studies. Autologous stem cell transplantation (auto-SCT) after high-dose melphalan chemotherapy can result in a prolonged response duration and survival in patients under 65 years of age. DESIGN AND SETTING Single-center, retrospective study of patients treated at Paoli-Calmettes Institute Cancer Centre, between January 1994 and January 2007 (96 months) PATIENTS AND METHODS We compared the outcome of elderly (age >65 years) patients with younger patients aged between 60 and 65 years with MM. RESULTS We compared 82 elderly patients with 104 younger patients. Except for age, both groups had comparable demographic features, disease characteristics, and prognostic factors. Induction VAD chemotherapy was comparable between the elderly (87%) and younger (94%) group. Prior to auto-SCT, the calculated hematopoietic cell transplantation-specific co-morbidity index was also comparable. With a median follow-up of 41 months (range, 5-227 months) after auto-SCT, 120 patients were still alive. Disease progression (n=40; 61%) was the main cause of death, and it was comparable in the two groups. Auto-SCT-related mortality was 3.8% (n=4/104) in younger and 3.7% (n=3/82) in older patients. Comparing younger/older subjects, progression-free survival was significantly higher in the younger group (P<.0001). However, disease response rates after the first auto-SCT was comparable and overall survival (OS) was also comparable (57% vs. 54% at 5 years, P=NS; 32% vs. 24% at 10 years, P=NS). In a Cox multivariate analysis model, none of the relevant characteristics was shown to be a critical prognostic feature for OS. CONCLUSIONS Age was insignificant for both OS and transplant-related mortality. We conclude that there is no biological justification for an age-discriminate policy for MM therapy. Physiologic aging is likely more important than chronologic aging.

Abstract
Background: High-dose chemotherapy with autologous stem cell transplantation is a cornerstone in the first-line treatment of multiple myeloma patients. However, only few factors have been identified affecting the outcome in such patients. We hypothesised that varying levels of mobilised CD34+ cells confer prognostic information in myeloma patients undergoing high-dose chemotherapy. Methods: We determined circulating CD34+ cells at the day of peripheral stem cell collection in 158 consecutive myeloma patients between January 2001 and August 2010. Patients were stratified into two groups (super vs normal mobilisers) with a cutoff of 100 000 peripheral CD34+ cells per ml. Results: We found that patients with more than 100 000 peripheral CD34+ cells per ml had a better overall survival (P=0.005) and a prolonged time to progression (P=0.0398) than patients with CD34+ cell counts below 100 000 CD34+ cells per ml. High levels of CD34+ cells were an independent marker for better overall survival and time to progression in a multivariate analysis that included disease stage, response at transplant, light-chain subtype, age, sex, and height. Conclusion: Our results suggest that high levels of mobilised peripheral CD34+ cells are associated with favourable outcome in myeloma patients undergoing autologous transplantation.

Abstract
Patients with multiple myeloma undergoing autologous haemopoietic stem cell transplantation (ASCT) are at high risk for infectious complications. Peri-transplant intravenous immunoglobulin (IVIG) has been used with the aim of reducing these risks. Our retrospective, non-randomised study of peri-transplant IVIG use and effect on infectious complications in 266 ASCTs for myeloma from 2000 to 2009 at a major metropolitan referral centre for haematological malignancies found no difference between those receiving peri-transplant IVIG (0.4 g/kg) (n=130) and those who were not (n=110) with regard to bloodstream infections, pneumonia, urinary tract or gastrointestinal infections. When analysed according to pre-transplant therapy (conventional chemotherapy versus novel agents), there was no significant difference in infectious complications between those who did or did not receive peri-transplant IVIG. In conclusion, our study did not show a benefit for the use of peri-transplant IVIG (0.4 g/kg) to reduce infectious complications in a large cohort of patients with myeloma undergoing ASCT. In the absence of data supporting efficacy in this context, there appears to be no benefit in the routine use of IVIG for this purpose.

Abstract
Outcomes for patients with multiple myeloma have dramatically improved during the past 20 years as a result of improved therapeutic options and a better understanding of malignant plasma cell biology. Until the past 10 years, the major limitations on improving outcomes were related to the minimal efficacy of existing agents and balancing the toxicity of therapy in an older patient population. However, despite these limitations, there have been advances that have resulted in improvements in progression-free survival and overall survival (OS). High-dose therapy and autologous transplant were the first among therapies to demonstrate an improvement in OS; but more recent analyses have demonstrated that there can be improvement in OS, which is also associated with improvement in the complete response (CR) rate, even among nontransplant patients as well. Thus, achieving CR has been associated with improved OS and has become a therapeutic goal. In the current era of new agents, such as thalidomide, bortezomib, and lenalidomide, the fraction of patients who achieve a CR is now greater than before, and the data regarding the importance of achieving this benchmark of response have never been more benefit.

Abstract
BACKGROUND As rare myelomas, i.e. the IgD, IgE, IgM and non-secretory forms, constitute only a small proportion of any study, relatively little is known about their prognosis in the era of peripheral stem cell transplantation. DESIGN AND METHODS We used the European Group for Blood and Marrow Transplantation Myeloma Database to compare the outcome following autologous transplantation of over 20,000 patients with common myelomas (IgG, IgA and light chain myeloma) with the outcome of patients with rare myelomas: 379 IgD, 13 IgE, 72 IgM and 976 non-secretory cases. RESULTS The study confirms the multiple adverse prognostic factors seen in IgD myeloma. Somewhat surprisingly, patients with IgD and non-secretory myeloma both had higher complete remission rates before and after transplantation than patients with common myelomas. However, while the overall survival of patients with non-secretory myeloma was similar to that of the patients with common myelomas, the survival of patients with IgD myeloma was significantly worse (although better than survival rates reported for non-transplanted patients); this was due to higher transplant-related mortality and relapse/progression rates. The post-transplantation survival of patients with IgE or IgM myeloma appears to be very poor. CONCLUSIONS This study provides data on the biological features of rare myelomas. The overall survival of patients with IgD, IgE or IgM myeloma is poor following autologous transplantation but substantially better than that reported for patients who were not transplanted.

Abstract
The goal of treatment for multiple myeloma (MM) is to improve patients' long-term outcomes. One important factor that has been associated with prolonged progression-free and overall survival is the quality of response to treatment, particularly achievement of a complete response (CR). There is extensive evidence from clinical studies in the transplant setting in first-line MM demonstrating that CR or maximal response post-transplant is significantly associated with prolonged progression-free and overall survival, with some studies demonstrating a similar association with postinduction response. Supportive evidence is also available from studies in the nontransplant and relapsed settings. With the introduction of bortezomib, thalidomide, and lenalidomide, higher rates of CR are being achieved in both first-line and relapsed MM compared with previous chemotherapeutic approaches, thereby potentially improving long-term outcomes. While standard CR by established response criteria has been shown to have differential prognostic impact compared with lesser responses, increasingly sensitive analytic techniques are now being explored to define more stringent degrees of CR or elimination of minimal residual disease (MRD), including multiparameter flow cytometry and polymerase chain reaction. Demonstrating eradication of MRD by these techniques has already been shown to predict for improved outcomes. Here, we review the prognostic significance of achieving CR in MM and highlight the importance of CR as an increasingly realizable goal at all stages of treatment. We discuss clinical management issues and provide recommendations relevant to practicing oncologists, such as the routine use of sensitive techniques for assessment of disease status to inform evidence-based decisions on optimal patient management.

Abstract
To study the impact of auto-SCT on the outcomes in African Americans (AA) with multiple myeloma (MM), we evaluated 101 consecutive AA patients who underwent auto-SCT. The median PFS and OS were 15.6 and 50.8 months, respectively. The median OS from diagnosis was 60 months. Traditional pre and post transplant prognostic variables earlier examined in Caucasian Americans (CA), including beta-2 microglobulin (B2M), chromosome 13 deletion, CR status after auto-SCT, gender, stage, Ig subtype, time to transplant, number of prior regimens and presence of lytic lesions, were not predictive of improved PFS or OS on univariate analysis. Age, lower CD34 cell dose infused, history of palliative radiation therapy (XRT) prior to auto-SCT and refractory disease at the time of auto-SCT were predictive of inferior PFS. History of palliative XRT was the only predictive factor of inferior PFS and OS after auto-SCT on multivariate analysis. In conclusion, MM in AA tends to relapse early after auto-SCT. It is unclear whether early relapses impact OS. Common prognostic peritransplant variables known in CA with MM may not be applicable to AA with MM.

Abstract
Nonsecretory myeloma (NSM) accounts for <5% of cases of multiple myeloma (MM). The outcome of these patients following autologous stem cell transplantation (ASCT) has not been evaluated in clinical trials. We compared the outcomes after ASCT for patients with NSM reported to the Center for International Blood and Marrow Transplant Research (CIBMTR) between 1989 and 2003, to a matched group of 438 patients (4 controls for each patient) with secretory myeloma (SM). The patients were matched using propensity scores calculated using age, Durie-Salmon stage, sensitivity to pretransplant therapy, time from diagnosis to transplant, and year of transplant. Disease characteristics were similar in both groups at diagnosis and at transplant except higher risk of anemia, hypoalbuminemia, and marrow plasmacytosis (in SM) and plasmacytoma (more in NSM). Cumulative incidence of treatment-related mortality (TRM), relapse, progression-free survival (PFS), and overall survival (OS) were similar between the groups. In multivariate analysis, based on a Cox model stratified on matched pairs and adjusted for covariates not considered in the propensity score, we found no difference in outcome between the NSM and SM groups. In this large cohort of patients undergoing ASCT, we found no difference in outcomes of patients with NSM compared to those with SM.

Abstract
Immunoglobulin (Ig) D multiple myeloma (MM) accounts for 2% of all MM cases and has been reported to be associated with poor prognosis compared with other MM subtypes. The aim of the present study was to compare the effects of high-dose melphalan treatment and autologous stem cell transplantation (ASCT) on the survival of patients with IgD MM and patients with other MM subtypes. Between November 1998 and January 2005, a total of 77 patients with MM who underwent ASCT at the Asan Medical Center were enrolled in this study. High-dose melphalan (total 200 mg/m2) was used as high-dose chemotherapy. The study population was divided into two groups based on MM subtype: those with IgD MM; and those with other MM subtypes. A total of 8 patients with IgD MM were identified, accounting for about 10% of the study population. Thirty-six patients (47%) had IgG MM, 17 patients (22%) had IgA MM, and 16 patients (20%) had free light-chain MM. The two groups were similar in baseline characteristics. The median follow-up was 17 months and the median overall survival (OS) was 39 months. In the IgD MM group, median eventfree survival (EFS) and OS were 6.9 and 12 months, respectively. In the patients with other MM subtypes, median EFS and OS were 11.5 and 55.5 months (p=0.01, p<0.01), respectively. Multivariate analysis of all patients identified IgD subtype (p=0.002) and Southwest Oncology Group (SWOG) stage 2 or greater at the time of ASCT (p=0.01) as adverse prognostic factors for survival. In this small study at a single center in Korea, patients with IgD MM had poorer outcomes after ASCT than did patients with other MM subtypes.

Abstract
BACKGROUND We have previously demonstrated that vincristine, liposomal doxorubicin and dexamethasone (VAD-doxil) is equally effective with VAD-bolus yielding objective response rates of 61% as first-line treatment in multiple myeloma (MM). In a phase II study, the addition of thalidomide to VAD-doxil (TVAD-doxil) proved feasible and increased response rate to 74%. The aim of the present multicenter prospective randomized clinical trial was to compare the efficacy and toxicity of VAD-doxil and TVAD-doxil in previously untreated MM patients. PATIENTS AND METHODS We enrolled 232 newly diagnosed MM patients aged <75 years, 115 randomized to VAD-doxil (arm A) and 117 to TVAD-doxil (arm B). Patients in arm A received vincristine 2 mg i.v. and liposomal doxorubicin 40 mg/m(2) i.v., on day 1 and dexamethasone 40 mg p.o. daily on days 1-4, 9-12 and 17-20 for the first cycle and on days 1-4 for the next three cycles. Patients in arm B received additionally thalidomide 200 mg p.o. daily, at bedtime. Treatment was administered every 28 days. RESULTS On an intention-to-treat basis, at least partial response was observed, in 62.6% and in 81.2% of patients randomized to arms A and B, respectively (P = 0.003). Progression-free survival (PFS) at 2 years was 44.8% in arm A and 58.9% in arm B (P = 0.013). Overall survival (OS) at 2 years was 64.6% and 77%, in arms A and B, respectively (P = 0.037). Considering overall toxicity, constipation, peripheral neuropathy, dizziness/somnolence, skin rash and edema were significantly higher in arm B compared with arm A (P < 0.01), but grade 3-4 toxicities were low and similar in both arms. CONCLUSIONS The addition of thalidomide to VAD-doxil increases response and PFS rates and probably OS in previously untreated myeloma patients. The superiority of efficacy counterbalances the higher overall toxicity of TVAD-doxil.

Abstract
Along with improved supportive care and thus reduced treatment-related mortality, an increasing number of elderly patients (> 60 years) with haematological malignancies are now considered for high-dose therapy (HDT) supported by autologous stem cell transplantation (ASCT). ASCT is feasible in selected elderly patients with multiple myeloma and those with non-Hodgkin's lymphoma. As elderly patients have generally been excluded from randomized studies evaluating efficacy of ASCT in comparison with non-transplant approaches, limited data are available on the efficacy of ASCT in this patient population. Recent developments in supportive care including amifostine and palifermin may increase feasibility of ASCT in elderly patients. Prospective studies are needed to evaluate feasibility and efficacy of ASCT in patients over 60 years of age. Also, further studies are needed in order to decrease toxicity of high-dose regimens in this patient group where co-morbid conditions may modify the toxicity of HDT in a clinically significant manner.

Abstract
The adverse prognostic role of cytogenetic abnormalities has recently been established in plasma cell dyscrasias. Modern techniques such as fluorescence in situ hybridization and comparative genomic hybridization have revealed a higher incidence of cytogenetic abnormalities in patients with multiple myeloma (MM) compared to conventional cytogenetics. Hypodiploidy and chromosome 13 abnormalities are found in more than 50% of myeloma patients, representing well known factors with adverse prognosis. Rearrangements involving the switch regions of immunoglobulin heavy chain (IgH) gene at 14q32 with various partner genes represent the most common structural abnormalities, having an incidence of 70% in MM. Structural abnormalities of chromosomes 17 and 8 involving the p53 and c-myc genes are considered to be less frequent events, but carry a poor prognosis. New therapeutic approaches such as non-myeloablative allotransplantation and modern therapeutic agents (thalidomide, lenalidomide, and bortezomib) and their combinations give promise for an improved therapeutic management of patients with MM. The detection of t(4;14), t(14;16), deletion of chromosome 13 on metaphase analysis, or deletion of p53 by FISH will define high-risk prognostic groups that are not generally controlled with high-dose melphalan and autologous stem cell transplantation (ASCT), and should therefore be treated with more investigational therapies. Alternatively, eligible patients who do not have these poor risk factors are more likely to benefit from a high-dose, melphalan-based, regimen followed by ASCT.

Abstract
Multiple myeloma is a disease of the elderly. Survival outcomes remain unacceptably low in older adults with multiple myeloma. To date, no obvious difference in tumor biology has been elucidated to explain the survival disparity between older and younger patients. Multiple factors including comorbidity, performance status, decreased physiologic reserve and potentially undertreatment contribute to poor outcomes in elderly patients with multiple myeloma. High-dose chemotherapy with autologous stem cell transplantation (ASCT) is increasingly being used to treat elderly patients with multiple myeloma in an effort to improve survival outcomes. Recent case comparison studies, and preliminary transplant registry data suggest that selected older patients can be treated with high-dose chemotherapy effectively with similar toxicity and survival benefits compared to younger patients. Traditional upper age limits for autologous transplantation are being challenged along with the definition of 'elderly' itself. Ultimately, the role of high-dose chemotherapy with stem cell rescue in the upfront treatment of older adults with multiple myeloma can only be established by prospective randomized trials. In the process of designing studies to investigate the use of ASCT in older patients, multiple issues unique to the elderly population will need to be considered. First, it will be critical to develop and validate patient selection algorithms that incorporate measures of comorbidity, cognitive function, physiologic reserve and psychosocial function to identify patients most likely to tolerate and benefit from ASCT. Second, preparative and conditioning regimens will need to be further tailored to maximize the benefit to risk ratio. Finally, outcome measures in clinical trials should include disability and quality of life measures, which may be equally important in making treatment decisions for older patients. The future application and study of autologous transplantation in older patients with multiple myeloma provides a unique opportunity to challenge ageism and serve as a model for development of tailored assessments and interventions in this population.

Abstract
To determine the pattern and degree of hepatic transaminitis experienced by children undergoing autologous transplantation for neuroblastoma. Sixty-four children with high-risk neuroblastoma received an autologous transplant with cyclophosphamide, etoposide, and carboplatin conditioning. Forty-eight went on to receive a second transplant with M and TBI conditioning. Charts were reviewed for evidence of hepatic regimen-related toxicity. A high rate of transaminitis was observed after both regimens. In each transplant, there was an early period of transaminitis during conditioning, from which patients recovered, followed by a second period of transaminase elevation. The degree of elevation was not associated with age, whether the administered dose was calculated based on a per kg or per M(2) basis or the presence of regimen-related severe mucositis. Elevated transaminases at admission were not associated with maximal hepatotoxicity during the first transplant although there was an association in the second transplant. However, the magnitude of transaminase elevation was less in the second transplant. VOD occurred in one and three patients in transplants 1 and 2, respectively. Both conditioning regimens were associated with an early and late elevation of transaminases without significant cholestasis. This biphasic pattern of transaminitis has not been reported previously. The high prevalence of transaminase elevation at time of both transplants was not associated with an increased incidence of VOD. We conclude that elevated transaminases should not preclude proceeding to a first or second autologous transplant with these regimens.

Abstract
CONTEXT Nonsecretory plasma cell myeloma is characterized by an absence of detectable monoclonal protein in both the serum and urine. It is generally reported to comprise approximately 1% to 5% of all cases of plasma cell myeloma and, because of its rarity, requires a high index of suspicion and bone marrow biopsy to establish the diagnosis. OBJECTIVE Review the diagnostic strategy when nonsecretory plasma cell myeloma is a clinical consideration in light of a relatively new serum free light chain assay. DATA SOURCES Case study and review of the literature. CONCLUSIONS Initial data using a recently developed nephelometric serum free light chain assay suggests that only about one fourth of nonsecretory plasma cell myeloma cases may be truly nonsecretory. The definition of nonsecretory plasma cell myeloma should be modified to exclude cases with evidence of clonality using the serum free light chain assay.

Abstract
Limited information is available on the feasibility and efficacy of autologous stem cell transplantation (ASCT) in multiple myeloma (MM) patients >65 years of age. In 1995-2005, 22 myeloma patients >or=65 years (median 68, eight >or=70) and 79 patients <65 years (median 57) were included in an identical treatment protocol. The first progenitor cell mobilization with cyclophosphamide plus granulocyte-colony stimulating factor (G-CSF) was successful in 95 and 96% of the patients, respectively. To date, 92 patients have received MEL (melphalan) 200 mg/m2 supported by ASCT. No early treatment-related deaths were observed among 22 elderly patients, whereas one younger patient died early. Engraftment and the need for supportive care were comparable between groups. The elderly patients tended to have more WHO grade 3-4 oral or gastrointestinal toxicity when compared to the younger patients (45 vs 23%, P=0.06). After ASCT, a complete response was observed in 44% of the elderly patients and 36% of the younger patients, respectively. No difference was observed between these age groups in progression-free survival (23 vs 21 months) or overall survival (57 vs 66 months) after ASCT. We conclude that MEL200 is a safe and efficacious treatment in selected elderly myeloma patients.

Abstract
Multiple myeloma, for all practical purposes, remains an incurable malignancy; however, 5-year survival has improved substantially during the past 30 years. A major contribution to improved outcome is the use of high-dose chemotherapy and stem cell transplantation. This multifaceted approach to therapy requires an understanding of appropriate induction therapy, techniques for stem cell mobilization, appropriate conditioning and supportive care. Also of importance are prognosis, features that predict outcome, the suitability of transplant candidates, and post-transplantation maintenance therapy.

Abstract
Autologous (ASCT) and allogeneic stem cell transplantations (alloBMT) are well-established therapies for multiple myeloma. However, patients continue to relapse at a constant rate. We present here 15 out of 163 patients who underwent SCT and relapsed with plasmacytomas only without evidence of bone marrow disease progression (14/147 post-ASCT and 1/16 post-alloBMT). The median time from SCT to plasmacytoma relapse was 24 months. The sites of plasmacytoma included bone, skin, rectum, and testicles. Five patients were treated with local radiotherapy, while seven patients received a combination of radiotherapy and chemotherapy or thalidomide, and two patients received chemotherapy alone with or without thalidomide. The recipient of alloBMT was initially treated with VAD-chemotherapy and local radiotherapy followed by a mini-allograft from the original donor. Eleven patients died at a median of 10 months following diagnosis of the plasmacytoma. Four are still alive, 12-20 months post-plasmacytoma diagnosis. These cases of unconventional disease recurrence are likely to be seen due to sub-clinical seeding of tumour cells suggestive of the presence of an extramedullary (EM) clone of plasma cells with a high degree of chemoresistance. We also review all the available data in the literature for the optimal therapy for patients with isolated EM relapse.

Abstract
BACKGROUND High-dose treatment with autologous stem cell transplantation (ASCT) has become the standard of care for patients with myeloma below the age of 65 years. AIMS We report an audit of 60 patients (median age: 52.5 years) who underwent ASCT in the National Bone Marrow Transplant centre in St James's Hospital in Dublin between 1997 and 2003 inclusive. METHODS Clinical and laboratory data were retrieved from patient medical records and hospital information management systems. RESULTS Thirty-six patients had IgG, 11 IgA, 1 IgD, 9 light chain and 3 non-secretory MM. Fifty-seven (95%) patients received anthracycline-corticosteroid combination chemotherapy prior to autografting. There was no transplant-related mortality (TRM). Complete (CR) and Partial Responses (PR) were seen in 16 (29.6%) and 29 (53.7%) of those evaluable (n = 54 (90%)). The actuarial Progression-Free (PFS) and Overall Survival (OS) rates at five years are 13% and 55% respectively. CONCLUSION Centre outcome is comparable to published international series and supports the use of ASCT in the treatment of this malignancy.

Abstract
The aim of this study was the evaluation of the effect of intermediate doses of thalidomide with dexamethasone (Thal/Dex) on disease course and bone disease in patients with refractory/relapsed myeloma who were under zoledronic acid therapy. We studied 35 patients, who received thalidomide at a dose of 200 mg/daily. We measured, pre-, 3 and 6 months post-treatment soluble receptor activator of nuclear factor-kappaB ligand (sRANKL), osteoprotegerin (OPG), osteopontin (OPN), markers of bone resorption and formation. Before treatment, patients had increased levels of sRANKL/OPG ratio, bone resorption markers and OPN, while they had suppressed bone formation. The pretreatment sRANKL/OPG ratio correlated with the extent of bone disease. Thal/Dex administration resulted in a significant reduction of sRANKL/OPG ratio, and bone resorption. Bone formation, OPG and OPN did not show any alteration. Changes of sRANKL/OPG ratio correlated with changes of bone resorption markers. Thal/Dex was given for a median time of 10 months and the median follow-up period was 22 months. The response rate was 65.7%. The median survival was 19.5 months. beta2-microglobulin, type of response and International Staging System predicted for survival. These results suggest that the combination of intermediate dose of Thal/Dex is effective in patients with refractory/relapsed myeloma and improves abnormal bone remodeling through the reduction of sRANKL/OPG ratio.
