Abstract Background: Primary systemic amyloidosis (AL) is a rare plasma cell clonal disorder(8/million) characterized by extracellular deposits of material composed mainly of fragments of light chain immunoglobulin throughout a body. Standard chemotherapy (e.g. melphalan and prednisone) is associated with poor outcomes (typical median survival is between 12–18 months with less than 5% survive 10 years). Autologous stem cell transplant (ASCT) has been increasingly advocated for treatment of AL. However, it is uncertain whether ASCT is better than standard chemotherapy. To address this uncertainty, we undertook a systematic review/meta-analysis to evaluate the efficacy of high-dose chemotherapy and autologous stem-cell transplant (HSCT) versus conventional chemotherapy in patients with AL. Methods: Data search of published studies included Medline [all randomized controlled trials (RCTs)], Cochrane library and hand search of references. Studies were included if they were comparison trials of HSCT versus conventional chemotherapy, regardless if they were RCTs, prospective studies with historical control, or single arm studies. The studies were eligible if patients had biopsy proven AL with at least one major organ involved. Data were extracted on benefits as well as harms (overall survival, event-free survival, response, treatment related mortality, treatment-related morbidity). Results: Out of 34 identified studies only 13 met the inclusion criteria for the current systematic review (2 RCTs, 2 prospective non-randomized trials involving historical control, and 9 single arm trials). Altogether these trials enrolled 1056 patients. Pooled data from 4 trials with controls (RCT and non-RCT) found similar overall survival for ASCT and conventional therapy arms [hazard ratio (HR) of 1.10 (95% CI 0.88, 1.36, p=0.4); p= 0.6]. Analysis of data according to trial design also did not find any difference in survival [HR for RCTs was 1.10 (95% CI 0.88, 1.37) and for non RCTs HR was 0.98 (95% CI 0.29, 3.35)]. The complete hematological response was also similar in both arms in RCTs (Odds ratio [OR]=1.38, 95%CI 0.67, 2.85; p=0.4) and non RCTs (OR=1.78, 95%CI 0.22, 14.65; p=0.32). The pooled proportion of treatment-related deaths in the single arm studies for AHCT was 0.119 (95% CI = 0.09 to 0.14)]. Conclusion: The results from the meta-analysis indicate that there is no statistically significant difference between the treatment effects from high-dose chemotherapy with ASCT and conventional chemotherapy. Hence, the efficacy of ASCT in improving overall survival and complete hematological response remains to be proven.

Abstract Background Chromosomal abnormalities detected by interphase fluorescence in situ hybridization (I-FISH) are an important prognostic marker in patients with multiple myeloma (MM). Isolated chromosome 13q has been considered standard risk when identified by I-FISH and high risk by conventional cytogenetics. The impact of additional cytogenetic abnormalities with chromosome 13q identified by I-FISH in regards to prognosis has not been fully defined. In this report, we describe the outcome of patient’s with multiple myeloma with isolated chromosome 13q and 13q+ (additional cytogenetic abnormalities) identified by I-FISH at our institution between January 2003 and January 2013 and had I-FISH analysis prior to treatment. Methods The primary objective was to compare patient’s outcomes in regards to response, time to progression, and overall survival between patients who had an isolated 13q and 13q+ identified by I-FISH in the bone marrow plasma cells. Kaplan & Meier curves were generated to calculate overall survival (OS) between the two groups. Results Between January 2003 and January 2013, we identified 76 patients by I-FISH who had either an isolated 13q or 13q+ in patients with multiple myeloma (Patient characteristics Table 1). Of the patients with an isolated 13q abnormality 33% received a bortezomib-based regimen and 38% in the 13q+ group. Of the patient’s with a isolated 13q 38% went onto receive high dose chemotherapy followed by autologous stem cell transplant (ASCT) while 20% with a 13q+ received ASCT. African American patients with 13q consisted of 65% and 60% with 13q+ in our patient population. For the 13q or 13q+ who underwent high dose chemotherapy followed by autologous stem cell transplant OS was 85% compared to the non-transplant group 45% (p=0.01) (Figure 2). On follow up at a median of 2.5 years mortality occurred in 31% of the 13q patients compared to 62% in the 13q+ group. The overall survival at 5 years was 25% in the 13q+ group compared to 65% in the patient’s with an isolated 13q, With the 13q+ group having an overall poor OS (p=0.03) Conclusion Patients who harbor the 13q and additional cytogenetic abnormalities identified by I-FISH have a significant worse outcome compared to patients with an isolated 13q. These patients should be considered high risk and consideration for treatment with novel agents and autologous stem cell transplant followed by post-transplant maintenance therapy should be considered.

Abstract The addition of Rituximab to standard combination chemotherapy has significantly improved outcomes in both young and elderly patients with Non-hodgkins lymphoma (NHL). High dose chemotherapy with autologous stem cell transplant is currently the standard of care for patients with relapsed hodgkins lymphoma (HL) and NHL. However the effect of the addition of Rituximab to standard high dose chemotherapy regimen for autologous stem cell transplant on neutrophil and platelet engraftment is unknown. There are however, reported cases of neutropenia developing in patients treated with Rituximab. We performed a retrospect review of all patients with HL and NHL treated in our institution with RBEAM (Rituximab, Carmustine, Etoposide, Cytarabine, Melphalan) chemotherapy between July 2000 and June 2005 and compared it to patients receiving BEAM in the same time period. Rituximab was given at a dose of 375mg/m2 one day prior to beginning standard BEAM high dose chemotherapy. Peripheral blood was the main source of stem cells. The purpose of this study was to determine the effect of the addition of Rituximab on neutrophil and platelet engraftment. A total of 46 patients were treated during this time period. Twelve patients received RBEAM and 34 received BEAM. There was a statistical significant difference in age between the two groups. There was however no difference between the two groups in terms of race, sex and primary diagnosis. Median stem cell dose was not significantly different between the two groups. Characteristic of both groups are shown in Table: 1 Characteristics of Both Groups Median Age (yrs) Race Diagnosis Median Stem Cell Dose(x10^6) AA White HL NHL RBEAM 50.5 3 9 3 9 3.9 BEAM 36 13 21 17 17 3.8 P-VALUE 0.01 0.49 0.2 0.54 Neutrophil engraftment was defined as the first day of ANC > 500 on 3 consecutive days. Platelet engraftment was defined as the first day of platelet count > 20,000 with no platelet transfusion in the next seven days. The median time to neutrophil engraftment was 12 day in RBEAM compared to 11 days in BEAM (p=0.09). Platelet engraftment was however significantly delayed in patients receiving RBEAM 18days versus 12 days for BEAM (p= 0.02). Looking at both cohorts together we found that patients with HL had a significant delay in platelet engraftment compared to those with NHL (p=0.04). However there was no difference in neutrophil recovery. Although, stem cell dose affected neutrophil recovery, it had no effect on platelet engraftment. There was no increased toxicity in the early post transplant period associated with the addition of Rituximab. No bleeding complications resulted form the delay in platelet engraftment in the patients who received RBEAM. In a linear regression model the only factor that significantly affected engraftment was conditioning regimen. We conclude that the addition of Rituximab to standard high dose BEAM chemotherapy for autologous stem cell transplant has no effect on neutrophil engraftment; however platelet engraftment may be delayed. The continue use of this regimen despite the small delay in platelet engraftment will depend on whether there is any benefit, in terms of response rate, progression free and overall survival.

Abstract Background Diffuse large B-cell lymphoma (DLBCL) accounts for 30% to 40% of non-Hodgkin’s lymphoma (NHL) cases in Western countries. Although two-thirds of patients may be cured with combination chemotherapy, in the event of treatment failure and for those who are refractory to treatment, survival is usually measured in months. Several therapeutic modalities have been utilized for patients with relapsed or refractory disease, but among patients who are not eligible for high-dose chemotherapy with stem cell transplant, a comprehensive assessment of efficacy and safety is lacking. This systematic literature review (SLR) was designed to exhaustively collect and review information on the clinical efficacy and safety of the different interventions used in the treatment of refractory or relapsed DLBCL, and if possible to perform a meta-analysis. Methods Electronic databases (PubMed, Cochrane Library, Embase) were searched for relevant studies published from 1997 to August 2, 2012. In addition, conference abstracts, bibliographic reference lists of included articles and recent reviews, and the Clinicaltrials.gov database were searched for phase 2, 3, or 4 studies displaying results, potentially unpublished in peer-reviewed journals. Main efficacy outcomes included objective response rate (ORR), complete response, partial response, duration of response, progression-free survival (PFS), and overall survival (OS). Safety endpoints focused on grade 3/4 toxicities and treatment discontinuation due to toxicity. Studies had to report on relapsed or refractory DLBCL after at least one standard treatment and patients who were not eligible to receive high-dose chemotherapy or stem cell transplant (autologous or allogeneic). Mixed type NHL studies were required to report DLBCL outcomes separately for inclusion. Results A total of 3,308 publications were identified in the first pass of a broad SLR on NHL; of these, 57 provided relevant data for DLBCL representing 54 unique studies. Of the 54 studies, there was 1 phase 3 study, 33 phase 2 studies, and 4 phase 1/2 studies (15 studies did not report the study phase and 1 was an observational study). Six studies were comparative (3 randomized trials; 3 nonrandomized trials) with two treatment arms; 48 studies were single arm. Of the 48 regimens evaluated, few regimens were represented more than once. Overall survival and PFS were often not reported or not reported separately for the patients with DLBCL in studies that enrolled patients with any of the multiple lymphoma histologies. Refractory and relapsed criteria were often not defined, and definitions were heterogeneous when available. The ORR from the few comparative studies ranged from 27% to 100%, with most estimates between 40% and 70%. PFS with low and high doses of obintuzumab was 2 months and 3 months, respectively in one study, and OS was 4 months with MEP and 7 months with C-MEP in another study. There was a common regimen in two of the randomized controlled trials, but the patient populations in these studies differed too greatly to allow a valid meta-analysis to be performed. In the single-arm studies, ORR ranged from 11% to 100%, with the estimates evenly distributed across that range. Progression-free survival was approximately 1 to 10 months. Reported median OS ranged from 1 to 13 months. Main safety concerns included thrombocytopenia, leukopenia, and neutropenia. Conclusions There is a high unmet need for effective therapies for patients with relapsed or refractory DLBCL who are ineligible for stem cell transplant. Although numerous regimens have been evaluated in single-arm trials and a handful in comparative studies, there is no clearly superior regimen for patients with relapsed or refractory DLBCL, especially in third- and later lines of therapy.
