Abstract Background. Autologous stem cell transplantation (ASCT) remains the standard of care for young multiple myeloma (MM) patients; indeed, at-home ASCT has been positioned as an appropriate therapeutic strategy. However, despite the use of prophylactic antibiotics, neutropenic fever (NF) and hospital readmissions continue to pose as the most important limitations in the outpatient setting. It is possible that the febrile episodes may have a non-infectious etiology, and engraftment syndrome could play a more significant role. The aim of this study was to analyze the impact of both G-CSF withdrawal and the addition of primary prophylaxis with corticosteroids after ASCT.Methods. Between January 2002 and August 2018, 111 MM patients conditioned with melphalan were managed at-home beginning + 1 day after ASCT. Three groups were established: Group A (n = 33) received standard G-CSF post-ASCT; group B (n = 32) avoided G-CSF post-ASCT; group C (n = 46) avoided G-CSF yet added corticosteroid prophylaxis post-ASCT.Results. The incidence of NF among the groups was reduced (64%, 44%, and 24%; P < 0.001), with a non-significant decrease in hospital readmissions as well (12%, 6%, and 2%; P = 0.07). The most important variables identified for NF were: HCT-CI > 2 (OR 6.1; P = 0.002) and G-CSF avoidance plus corticosteroids (OR 0.1; P < 0.001); and for hospital readmission: age ≥ 60 years (OR 14.6; P = 0.04) and G-CSF avoidance plus corticosteroids (OR 0.07; P = 0.05).Conclusions. G-CSF avoidance and corticosteroid prophylaxis post ASCT minimize the incidence of NF in MM patients undergoing at-home ASCT.

Abstract Introduction: Autologous stem cell transplantation (ASCT) remains the mainstay of treatment of multiple myeloma (MM) in patients <65 years old. However, most patients relapse after ASCT suggesting that additional treatment is needed. The Brazilian Multiple Myeloma Group designed a study to evaluate the impact of thalidomide maintenance after ASCT. Methods: From October 2003 to July 2008, 212 untreated patients <70 years old were enrolled in a prospective randomized multicenter study. All patients signed an informed consent and the protocol was approved by the Ethical Committees of each center. The treatment consisted of 3 phases: induction with 3–5 cycles of VAD; high-dose cyclophosphamide (4g/m2) plus G-CSF for stem cell mobilization; (3) melphalan 200 mg/m2 and ASCT. On day +60 post ASCT patients were randomized to receive dexamethasone (40 mg/d × 4 days every 28 days) with (arm A) or without (arm B) thalidomide (200 mg daily) for 12 months or until disease progression. Results: The median age was 55 years (27–70), 52% were male, the median serum beta-2 microglobulin was 3.66 mg/dl, 33% were ISS stage 3, 36% were ISS stage 2 and 24% had deletion of chromosome 13. In July of 2008, 93 patients (44%) were randomized: 54 in arm A and 39 in arm B. Reasons for non-randomization were: treatment related deaths during phases 1–3 (n= 39), disease progression (n= 22), ineligible or refused ASCT (n= 7), SMD after ASCT (n= 1), protocol violation (n= 3), abandoned (n= 19), and still in phases 1–3 (n= 28). Clinical characteristics of each group were similar. The median follow-up from diagnosis was 15 months. PFS in arms A and B were 42% (95% confidence interval [CI] 22–62) and 25% (95% CI 5–45), p= 0.07. A multivariate analysis that included baseline serum beta-2-microglobulin and deletion of chromosome 13 showed that maintenance with thalidomide was significantly associated with better PFS (hazard ratio 2.43, 95% CI 1.10–5.35, p=0.03). Overall survival was 65% in arm A (95% CI 35–95) and 74% in arm B (95% CI 44–100), p= NS. Conclusions: A high proportion of MM in Brazil has advanced disease at diagnosis, and this explains the high number of patients who did not reach the maintenance phase. This study shows that the addition of thalidomide to dexamethasone improves PFS after a single ASCT.

e19532 Background: High dose melphalan and autologous stem cell transplantation (ASCT) significantly prolong survival for patients with multiple myeloma (MM). The purpose of this study is to assess the effects of hemoglobin (Hgb) and serum creatinine (Crea) values at the time of transplantation on the overall outcome of patients with multiple myeloma treated at our transplant center. Material & Methods: This analysis included 247 consecutive patients who underwent ASCT for MM between 2010-2016. Hemoglobin was grouped as low or high relative to their sample median. Patients were also stratified according to serum Crea value at the time of transplantation ( < 2 or ³2 mg/dl). Results: The median age was 57 (29-75) years and most patients were male (n = 151, 61.1%), IgG subtype (n = 124, 50.2%), and ISS stage 3 (n = 122, 49.4%). The interval from the time of diagnosis to ASCT was median 7 months and median follow-up from ASCT was 49 months (range, 3-198 months). The most commonly induction regimens included VAD (vincristine, doxorubicin and dexamethasone) and VCD (bortezomib, cyclophosphamide, dexamethasone), respectively. Since maintenance was not an approved treatment in myeloma most patients did not receive any. For the entire cohort, the median Hgb and Crea were 11.5 g/dL and 0.9 mg/dL respectively. No difference in progression free survival (PFS) was observed between a lower and higher Hgb (82 vs. 81 months, p = 0.96). However, the median PFS was significantly longer in patients with a lower Crea compared to those with a higher Crea (83 vs. 48 months, p = 0.01). Patients with both a lower hemoglobin and higher Crea experienced shorter PFS compared to those with a higher hemoglobin and lower Crea (45 vs. 82 months, p < 0.001). We failed to demonstrate the impact of creatinin levels on time to neutrophil and platelet engraftment. There were no differences in OS according to lower vs. higher Hgb (58 vs. 52 months; p = 0.29, respectively) but in higher crea cohort worse OS was observed (41 months vs. 57 months; p = 0.02, respectively). Conclusions: We demonstrate that hemoglobin and creatinine represent important determinants of clinical outcomes after ASCT. A lower hemoglobin and higher creatinine, individually and when combined, were associated with shorter PFS. Therefore, further studies of larger randomized cohorts are required to clarify the impact of pre-transplant Hgb and Crea levels on ASCT outcomes.

Abstract The persistence of abnormal neoplastic plasma cells (APC) detectable in the bone marrow by flow cytometry at more than 3 months after autografting for multiple myeloma (MM) has been reported to predict early disease progression. In this study, we retrospectively reviewed the flow cytometric data from bone marrow aspirates of MM patients before and after autologous stem cell transplantation (ASCT). Light scatter properties and CD38 expression were used to identify plasma cells, and CD19/CD45/CD56 further distinguished normal plasma cells (NPC) from APC. Conventional response criteria (Blade criteria) and survival data were also collected. Forty-seven (47) patients treated with the same conditioning regimen were screened. Median follow up from ASCT was 19 months. After ASCT, 66% (31/47) patients achieved complete remission (CR)/very good partial remission (VGPR), as compared to only 36% (17/47) prior to ASCT. In 39 patients with data before and after ASCT, all 39 (100%) had a detectable abnormal plasma cell population identified phenotypically by flow cytometry prior to ASCT. Of these patient, 18/39 (46%) had greater than 30 APC and these patients had significantly shorter PFS independent of other covariates (1-sided P=0.036, 2 sided P=0.072, logrank). Twenty-six out of 39 patients (67%) also had detectable NPC. Following ASCT, the number of patients with detectable NPC increased to 35/39 (89%), while 3/39 (8%) had no detectable NPC and 1/39 (3%) had neither NPC or APC. The proportion of APC decreased significantly after transplant (81% prior to transplant vs. 59% post-transplant, P=0.008, 2 tailed t-test). Patients with a APC to NPC ratio &lt; 1 post transplant has higher PFS rate at 2 year (54%) when compared to patients with higher APC/NPC ratio (29% PFS at 2 year), however, the difference is not statistically significant. In addition to the presence of APC, the ratio of APC to NPC, age, beta-2 microglobulin levels, and the presence of normal immunoglobulin levels were analyzed. Patients who achieved CR/VGPR after transplant had significantly longer PFS (23 months vs. 11 months, P=0.03). All other covariates were not found to be significant. Because only 10 deaths were observed, covariate analysis for OS was not feasible. In conclusion, the recovery of NPC after ASCT is seen in a substantial propotion of patients with a trend towards better PFS in patients with low APC/NPC ratio. On the other hand, the presence of a significant population of APC (&gt; 30) prior to transplant appears to correlate with poorer PFS in MM patients.

In this prospective phase II clinical trial, multiple myeloma (MM) patients were randomized to receive a second (tandem) autologous stem cell transplantation (ASCT) based on whether they achieved a partial response or worse (≤PR) following initial ASCT (ASCT1). Patients who achieved a very good partial response or better (≥VGPR) had salvage ASCT at relapse. Seventy-five patients received conditioning therapy and ASCT1. A total of 44 patients (59%) achieved ≥VGPR, whereas 31 patients entered ≤PR and were offered tandem ASCT. In all, 20 patients agreed to tandem ASCT. Demographic and clinical characteristics were similar between the two cohorts except for median lactate dehydrogenase (LDH) ( P = 0.0141) and percentage of marrow plasma cells before ASCT1 ( P = 0.0047), both lower in the ≥VGPR group. Intent to treat analysis showed that patients who achieved ≥VGPR to ASCT1 had a trend toward improved progression-free survival (PFS) (37 vs. 26 months, P = 0.078) and superior overall survival (OS) (not reached vs. 50 months, P = 0.0073). Patients with ≤PR who declined tandem transplantation had shortened PFS (20 vs. 28 months, P = 0.05) but similar OS (53 vs. 57.5 months, P = 0.29) compared to those who received it. Thus, a favorable clinical response to ASCT1 identifies a low-risk group with superior long-term prognosis despite similar PFS.

Multiple Myeloma (MM) is one of the most common hematologic malignancies, with a heterogeneous prognosis. Therefore, the recognition of biomarkers can be useful to understand the differences in patient outcomes. Minimal Residual Disease (MRD) has been considered a very important prognostic factor in MM. In parallel, the prognostic value of immunophenotypic markers expressed in MM Plasma Cells (PCs) has also been described. The aim of this study was to assess the impact of CD27, CD28, CD45, CD56, CD117 and β2-microglobulin expressions on the outcome of 154 MM patients undergoing Autologous Stem Cell Transplantation (ASCT). The relation of each marker studied with the Overall Survival (OS) and Progression-Free Survival (PFS) was assessed, alone and in association with pre-ASCT MRD. Scores of good (GPM) and poor Prognostic Markers (PPM) were established, according to their respective survival curves. The expressions of CD27 and CD45 were associated to longer OS (p=0.013 and p=0.00, respectively) and PFS (p=0.00) as well as the absence of CD28 (OS p=0.026; PFS p=0.001) and CD56 (OS p=0.004; PFS p=0.009), in patients with undetectable MRD. The number of GPM showed an inverse correlation with the level of MRD (p=0.04), while a higher number of PPM was observed in patients with higher levels of MRD (p=0.04), which were also significantly associated with OS and PFS. In conclusion, although pre-ASCT MRD is a powerful prognostic factor in MM, these biomarkers can provide additional prognostic information and be used in the follow-up of MM patients.

Autologous stem cell transplantation is considered the standard of care for multiple myeloma patients aged < 65 years with no relevant comorbidities. The addition of drugs acting both on bone marrow microenvironment and on neoplastic plasma cells has significantly increased the proportion of patients achieving a complete remission after induction therapy, and these results are mantained after high-dose melphalan, leading to a prolonged disease control. Studies are being carried out in order to evaluate whether short term consolidation or long-term maintenance therapy can result into disease eradication at the molecular level thus increasing also patients survival. The efficacy of these new drugs has raised the issue of deferring the transplant after achivng a second response upon relapse. Another controversial point is the optimal treatment strategy for high-risk patients, that do not benefit from autologous stem cell transplantation and for whom the efficacy of new drugs is still matter of debate.
