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 Abstract 4127 In the age of novel targeted agents, autologous stem cell transplant (ASCT) remains the standard of care for younger patients with newly diagnosed multiple myeloma (MM), offering similar treatment responses and overall survivals as standard chemotherapeutic agents but with the added benefit of a prolonged treatment-free period. Nevertheless, a standard of care for stem cell mobilization for ASCT has yet to be determined. Even in the era of new mobilization agents such as Plerixafor, Cyclophosphamide (Cy) and G-CSF combination remains the preferred mobilizing approach for patients with MM. Several studies have shown that Cy improves the stem cell yield at the expense of increased toxicity, but whether the administration of this chemotherapeutic agent pre-transplant has any impact on the long-term event-free and/or overall survival of myeloma patients remains controversial. In this study, we present a retrospective analysis of 186 patients with newly diagnosed MM who underwent ASCT with high-dose melphalan 200 mg/m2 (HDM) between December of 2000 and 2008 at our Institution. Eighty-three patients were mobilized with single agent G-CSF and 103 patients received high dose Cy (4 gm/m2) and G-CSF combination. Patient characteristics were similar between the treatment groups, including: age, gender, disease stage, and disease status prior to transplant. However, toxicity post-mobilization with Cy/G-CSF was significantly higher compared with G-SCF alone, including: febrile neutropenia (23%), hemorrhagic cystitis (8%), GI toxicity (57%), re-hospitalization due to complications and transplant delay (14%). The overall post-transplant toxicity was similar in the 2 groups, though the treatment related mortality was slightly higher in the Cy/G-CSF arm (4% versus 2%). Post transplant responses were not significantly different in the 2 groups, with 60% of patients achieving a VGPR or better after ASCT in the G-CSF group and 49% in the Cy/G-CSF group (p = 0.33). The median event-free survivals (EFS) for the Cy/G-CSF and G-CSF cohorts were 21.6 and 22.6 months, respectively, (p = 0.62) yielding no significant difference (Figure 1). Similarly, with a median follow up for surviving patients of 34.3 and 32.7 months, the median overall survivals were 68.2 and 62.3 months (p = 0.23) for the Cy/G-CSF and G-CSF cohorts, respectively (Figure 2). This retrospective analysis confirms that the addition of high dose Cy as part of the mobilizing regimen offers no improvement on the transplant outcome for patients with newly diagnosed myeloma and should therefore only be used in cases of difficult stem cell mobilization.

ABSTRACT Aphantasia, the loss of mental imagery, is a rare disorder and even more infrequent when acquired. No previous cases have been identified that were caused by transplant-related treatment. We describe a case of acquired aphantasia in a 62-year-old male with refractory IgG kappa multiple myeloma after receiving an autologous stem cell transplant (ASCT) following high-dose melphalan with a complicated hospital admission. The etiology of aphantasia remains unidentified, but we provide viable explanations to include direct effects from ASCT treatment and indirect effects from transplant-related complications.

Chromosome 13Q

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.
