Outcomes of autologous stem cell transplant (ASCT) in multiple myeloma from a tertiary cancer center in India.

e17003 Background: ASCT is part of standard treatment in multiple myeloma (MM).We report the results of such transplants and evaluate the role of prognostic factors if any in our patients. Methods: Sixty-one patients who underwent ASCT between June 1993 and March 2010 were included. Twenty four patients received VAD like regimen. Nineteen patients received novel agent based therapies. Ten patients underwent cyclophosphamide based mobilisation while only G-CSF based mobilisation done in 51 patients. Stem cells were harvested from peripheral blood in all patients. Melphalan was used at 200 mg/m2 in 24 patients. Prognostic factors evaluated for overall (OS) and progression-free survival (PFS) were baseline hemoglobin and albumin, ISS stage, disease status at day 100 post transplant, use of maintenance treatment post transplant, response to first line chemotherapy, use of novel agents before transplant and time to transplant from diagnosis. Results: Median age was 46 years. Median baseline haemoglobin (Hb) and albumin were 9.7 g/dl and 3.9 g/dl respectively. At the time of transplant 36% were in complete remission (CR), 5% in very good partial response (VGPR) and 28% in partial remission (PR). Median time to engraftment of neutrophils and platelets was 12 and 17 days respectively. Grade III–IV oral mucositis was seen in 35%. Transplant related mortality was 8.0 %. The 5 year overall survival (OS) and progression free survival (PFS) were 73% and 33% respectively. OS was better for patients with pre-transplant Hb greater than 9.7 g/dl (P= .04) and those who achieved CR at day 100 post transplant (P= .03). Patients who received maintenance therapy showed trend towards better OS (P= .07). PFS was better for patients with baseline albumin greater than 3.9g/dl (P = .043), Hb greater than 9.7 g/dl (P = .027) and early stage disease by ISS staging system (P=.001). Conclusions: Our study confirms that ASCT in such patients is safe and effective. Baseline albumin and Hb, ISS stage, day 100 disease response and use of maintenance treatment are important prognostic factors affecting survival.

Significant Difference

Abstract Several factors influencing disease progression and survival have been identified in multiple myeloma (MM). We analysed a series of 49 consecutive patients with MM that underwent autologous haematopoietic progenitor cell transplant (HPCT) in one center regarding the following variables: use of G-CSF for haematopoietic recovery post-transplant; recovery of normal IgM levels at day +100 post-transplant; levels of lymphocytes namely of the CD4+ and CD8+ subsets also at day +100. Before 2006, all patients had G-CSF starting 24 hours after the cell infusion until neutrophil > 500×10^9/L in two consecutive days; in the years 2006–2008, no G-CSF was given to transplanted patients. A historical comparison was done and at the time of this study no significant difference in progression free survival (Kaplan-Meyer analysis), was detected between the two groups, possibly due to the shorter follow-up of the “no G-CSF” (n=19) group; nevertheless median progression free survival (PFS) in the “G-CSF” group was 12 months while median PFS was not attained in the “no G-CSF” group (median follow-up = 7 months). Post transplant IgM levels were also determined in 39 patients. Eighteen patients recovered normal IgM levels at day +100 (46.8 %) and 21 (53.8 %) did not. Comparison of Kaplan-Meyer curves for the two groups did not show any statistically significant difference but there is a sharp difference between median PFS of the “low IgM” (10 months) and the “normal IgM” (27 months) groups. CD4/CD8 ratio was determined in 18 patients at day +100. The ratio varied between 0 and 0.63 (median – 0.305). No correlation was found between post-transplant IgM recovery and CD4/CD8 ratio. In conclusion, in our series of MM patients treated with autologous HPCT we could not find a definite relationship between immunologic recovery and response to treatment although there is a trend to a better outlook of the patients which recover normal IgM levels. It is also uncertain whether use of G-CSF in the post-transplant period would have any effect on disease behaviour.

Abstract Background Lenalidomide is an effective agent for the treatment of multiple myeloma (MM). The IFM Group conducted a randomized double-blind placebo controlled trial investigating the efficacy of lenalidomide maintenance treatment after autologous transplantation (IFM 2005-02 trial). The results showed that lenalidomide maintenance therapy significantly prolonged progression-free survival (PFS). Methods The aim of the present study was to identify prognostic factors affecting PFS in the 614 patients enrolled in this study. Analysis was performed using an extended Cox model, complete response (CR) was entered into the model as a time varying covariate. Results With a median follow-up of 60.6 months (54.5-68) PFS since randomization was shorter in the placebo arm (23.8 months, 95% CI 21-27.3) than in the lenalidomide arm (45.6 months, 95% CI: 40-55.1) (p<.001). Multivariate analysis showed that lenalidomide maintenance treatment arm, female sex, and obtention of CR were favourable prognostic factors for PFS. Conversely, beta2microglobuline, deletion of chromosome 13 and induction treatment reinforced by DCEP were associated with reduced PFS. For patients not in CR before initiation of maintenance therapy lenalidomide arm improved significantly PFS. This advantage is still observed in the 129 patients in CR at time of initiation of maintenance treatment. Conclusion These results confirm that obtention of CR at any time during treatment is a major factor for improving PFS in MM patients receiving first-line treatment including autologous transplantation. In this setting our data and those of other studies seems to support that lenalidomide maintenance treatment could be an intereresting option for delaying progression. At this time the gain in PFS did not translate into an OS improvement Disclosures: Marit: janssen-cilag: Honoraria, upport for travel to meeting, meeting expenses, upport for travel to meeting, meeting expenses Other; celgene: support for travel to meeting, meeting expenses Other.

Background: Evidence from retrospective studies suggests that disease progression after first-line chemotherapy for metastatic non-small-cell lung cancer (NSCLC) occurs most often at sites of disease known to exist at baseline. However, the potential effect of aggressive local consolidative therapy for patients with oligometastatic NSCLC is unknown. We aimed to assess the effect of local consolidative therapy on progression-free survival. Methods: In this multicentre, randomised, controlled, phase 2 study, eligible patients from three hospitals had histological confirmation of stage IV NSCLC, three or fewer metastatic disease lesions after first-line systemic therapy, an Eastern Cooperative Oncology Group performance status score of 2 or less, had received standard first-line systemic therapy, and had no disease progression before randomisation. First-line therapy was four or more cycles of platinum doublet therapy or 3 or more months of EGFR or ALK inhibitors for patients with EGFR mutations or ALK rearrangements, respectively. Patients were randomly assigned (1:1) to either local consolidative therapy ([chemo]radiotherapy or resection of all lesions) with or without subsequent maintenance treatment or to maintenance treatment alone, which could be observation only. Maintenance treatment was recommended based on a list of approved regimens, and observation was defined as close surveillance without cytotoxic treatment. Randomisation was not masked and was balanced dynamically on five factors: number of metastases, response to initial therapy, CNS metastases, intrathoracic nodal status, and EGFR and ALK status. The primary endpoint was progression-free survival analysed in all patients who were treated and had at least one post-baseline imaging assessment. The study is ongoing but not recruiting participants. This study is registered with ClinicalTrials.gov, number NCT01725165. Findings: Between Nov 28, 2012, and Jan 19, 2016, 74 patients were enrolled either during or at the completion of first-line systemic therapy. The study was terminated early after randomisation of 49 patients (25 in the local consolidative therapy group and 24 in the maintenance treatment group) as part of the annual analyses done by the Data Safety Monitoring Committee of all randomised trials at MD Anderson Cancer Center, and before a planned interim analysis of 44 events. At a median follow-up time for all randomised patients of 12·39 months (IQR 5·52-20·30), the median progression-free survival in the local consolidative therapy group was 11·9 months (90% CI 5·7-20·9) versus 3·9 months (2·3-6·6) in the maintenance treatment group (hazard ratio 0·35 [90% CI 0·18-0·66], log-rank p=0·0054). Adverse events were similar between groups, with no grade 4 adverse events or deaths due to treatment. Grade 3 adverse events in the maintenance therapy group were fatigue (n=1) and anaemia (n=1) and in the local consolidative therapy group were oesophagitis (n=2), anaemia (n=1), pneumothorax (n=1), and abdominal pain (n=1, unlikely related). Interpretation: Local consolidative therapy with or without maintenance therapy for patients with three or fewer metastases from NSCLC that did not progress after initial systemic therapy improved progression-free survival compared with maintenance therapy alone. These findings suggest that aggressive local therapy should be further explored in phase 3 trials as a standard treatment option in this clinical scenario.

Abstract Background: Syndecan-1 (CD138) is a heparan sulfate bearing proteoglycan found on various epithelial cells as well as on B lineage cells depending on its stage of development. Syndecan-1 (CD138) is abundantly expressed by plasma cells, especially myeloma cells. The extra cellular domain along with the heparan sulfate side chains can be cleaved off the cell surface and can be detected in the serum as soluble syndecan. Syndecan possibly plays a multifunctional role in the biology of myeloma. It has been shown to be an independent prognostic factor in patients with multiple myeloma. It has also been shown to promote myeloma cell growth through different mechanisms. Its expression has also been suggested to correlate with bone disease in MM. Methods: In this study we studied serum levels of soluble syndecan in newly diagnosed MM patients enrolled in the Eastern Cooperative Oncology Group (ECOG) E9486 and its associated correlative laboratory clinical trial E9487. We evaluated the prognostic value of syndecan in MM and its relationship to other known prognostic factors for this disease. In addition, syndecan levels were correlated with clinical and laboratory markers of bone disease. Results: A total of 501 patients were studied and the median serum syndecan-1 was 158 ng/mL. Syndecan levels correlated positively with other prognostic factors and markers of tumor burden such as β2-microglobulin (correlation coefficient 0.3; P <0.00001), labeling index (0.25; <0.0001), creatinine (0.23; <0.0001), soluble IL6 receptor (0.3; <0.0001), BM plasma cell percentage (0.16; <0.0006), and disease stage (P=0.0007). Significant differences in the overall and progression free survival was found between two groups of patient separated using the median value as cut-off. The High syndecan group had a median overall survival of 36.3 months compared to 49.3 months for the low syndecan group (P < 0.0001). Similarly, the high syndecan group had progression free survival of 25.4 months compared to 33.5 months for the low syndecan group (P < 0.0001). In a proportional hazards model including syndecan-1 as well as labeling index, β2M, Platelet count, IL-6R, syndecan-1 retained its prognostic value for overall survival (HR 1.3, P = 0.021). Syndecan levels were correlated with various bone markers including C-terminal telopeptide of type I collagen (ICTP), osteocalcin (OC), C-terminal type I procollagen (PICP), bone-specific alkaline phosphatase (BAP), and tartrate resistant alkaline phosphatase (TRAP) and were found to correlate only with ICTP (0.25, P < 0.0001). No correlation was found between clinical markers of bone disease including presence of lytic lesions, osteoporosis and pathologic fractures on X-rays or bone pain. Conclusion: In this large study, we once again confirm the prognostic value of serum syndecan-1 levels in large group of patients with newly diagnosed myeloma. Syndecan-1 level correlates with other disease markers. Syndecan levels also correlated with ICTP, a marker of bone turnover, though no strong correlation was found between syndecan levels and clinical markers of myeloma bone disease. The biological basis of these finding needs further evaluation.

Abstract Abstract 4554 High-dose chemotherapy followed by autologous stem cell transplantation (ASCT) is currently standard treatment for younger patients with multiple myeloma, resulting in improved survival and response rate compared to conventional chemotherapy. Disease relapse, however, remains almost inevitable and thus the role of two successive (tandem) autologous stem cell transplants has been evaluated in chemorefractory patients as a means of prolonging duration of disease response. We retrospectively analysed the results of nine patients with chemorefractory disease treated at a single UK institution who received tandem ASCT between January 1998 and February 2009. There were six men and three women. Median age at diagnosis was 56 years (range, 42–65 years). Paraprotein isotype was IgG in eight patients and IgA in one patient. Median serum paraprotein level was 41g/L (range 12–73g/L) at presentation. At time of 1st transplant six patients were in stable disease (SD) and three had evidence of progressive disease. Conditioning melphalan dose was 140mg/m2 in all but two patients who received 110mg/m2 and 200mg/m2. Median time between transplants was 3.7 months (range 2.3–6.4 months) with PR and SD being observed in 2/9 and 7/9 patients at time of 2nd transplant. None of the patients reached complete response (CR). One patient received melphalan 140mg/m2 prior to 2nd transplant. The remaining patients received melphalan 200mg/m2. Median follow up after tandem transplant was 54.3 months (range 15.6 –143.6 months). No treatment related mortality was reported. At the time of analysis, six patients were still alive and under follow up with an overall survival (OS) figure for the group of 52% at 10 years from diagnosis (Figure 1). Median progression free survival (PFS) was 20 months from 2nd transplant (range 6.7–62.6 months) (Figure 2). Tandem autologous stem cell transplant in chemorefractory patients has resulted in overall survival similar to autologous stem cell transplant in chemosensitive patients and should be considered in patients with chemorefractory disease.

Background High dose chemotherapy followed by an autologous stem cell transplant (auto-HCT) is considered standard of care in patients with newly diagnosed multiple myeloma (MM). In a recent randomized trial, median progression free survival (PFS) after auto-HCT, with or without maintenance therapy was 46 and 27 months, respectively (McCarthy P et al. NEJM 2012). However, about 15% of patients are reported to have much longer PFS (Pineda-Roman M et al. Cancer 2008). Here we tried to identify the factors that may predict a long PFS after auto-HCT. Methods We performed a retrospective chart review of patients who received an auto-HCT for MM between January 2000 and March 2007. A total of 1135 patients underwent an auto-HCT during this period, and 194 patients (17%) had a minimum PFS of 72 months or longer after a single auto-HCT. The primary objective was to determine the variables associated with a long PFS and overall survival (OS). Results Patient characteristics and outcomes are shown in the attached Table. The median age at auto-HCT was 56 years, and the median time from diagnosis to auto-HCT was 7.5 months. Twenty-three (13%) patients had ≥ 10% plasma cells in the bone marrow at auto-HCT and only 9 patients (4.8%) had high-risk cytogenetic abnormalities. One-hundred and fifty (77%) patients received induction therapy containing either an immunomodulatory (IMiD) agent or a proteasome inhibitor (PI). At the time of the auto-HSCT, only 13 (6.7%) patients were in CR and 38 (19.6%) were CR or VGPR after induction therapy (Table). One-hundred and sixty three (84%) patients received mephalan alone as conditioning regimen. Eighty-one (42%) patients received post auto-HCT maintenance. Eighty (41%) patients achieved a CR, while 104 (54%) achieved CR + VGPR after auto-HCT. Six patients (3.1%) developed a second primary malignancy post- autologous transplant. After a median follow-up of 95.4 months, median PFS was 97.3 months and median OS has not been reached. The 10-year PFS and OS were 41% and 73% respectively. Use of melphalan alone as preparative regimen was associated with a longer PFS and OS (p=0.004 and 0.004, respectively). Achievement of CR after auto-HCT was associated with a longer PFS only (p=0.001), and the use of IMiD or a PI as induction was associated with a longer OS (p=0.01). Conclusion Approximately 17% patients achieved a median PFS of 6 years or longer after a single auto-HCT. The long PFS in this cohort may be associated with younger age, low incidence of HR cytogenetics, use of an IMiD or PI as induction therapy, relatively low disease burden at auto-HCT, transplant from the year 2000 onwards, achievement of CR in >40% and the use of melphalan alone as preparative regimen.

Abstract Backgrounds: Allogeneic Hematopoietic Cell Transplantation (HCT) is a potentially curative treatment for fit patients with relapsed/refractory multiple myeloma (MM). When a HLA-identical donor is not available, haploidentical HCT (haploHCT) represents an acceptable therapeutic option, especially when post-transplant cyclophosphamide (PT-Cy) is used as anti-GVHD prophylaxis. Patients and methods: Twenty-nine patients (median age 56 years, range 47-70) undergoing myeloablative (n=15) or reduced-intensity (n=14) haploHCT from February 2011 to November 2015 are included in this retrospective analysis. The median number of previous lines of therapy was 2 (range 1-7) with 27 (93%) of patients having previously performed an autologous HCT. Both bortezomib and lenalidomide were used in 27 (92%) patients before haploHCT. Eighteen patients (62%) had chemosensitive disease at time of haploHCT (CR=4, VGPR=9, PR=5) and 11 (38%) had chemorefractory disease (PD=7, SD=4). Graft source was marrow-derived in 59% (n=17) and peripheral blood in 41% (n=12) of patients. Standard post-transplant cyclophosphamide anti-GVHD prophylaxis (50mg/mq day +3 and +4 or +5) plus mycophenolate and cyclosporine (n=24) or tacrolimus (n=3) or rapamycine (n=2) was used for the whole study cohort. Overall survival (OS) and Progression Free Survival (PFS) were performed with Kaplan-Meier analysis. Neutrophil and platelets engraftment, acute GVHD, chronic GVHD, Non-Relapse-Mortality (NRM) and Relapse Incidence/Progression of Disease (RI/POD) were obtained with competing risk analysis. Results: At day +30, neutrophil and platelets engraftments were 86% (95%CI:65-95) and 59% (95%CI:38-74), respectively. Acute GVHD grade >2 at days +100 and +180 were 38% (95%CI: 20-55%) and 41% (95%CI: 23-59%), respectively. All grade chronic GVHD at 12 and 18 months was 21% (95%CI: 8-37. At 18 months, RI/POD was 39% (95%CI:20-58%) and NRM 15% (CI95%:5-32). With a median follow-up in survivors of 16 months (range 5-55 months), the 18-month OS and PFS were 68% (95%CI: 47-82%) and 34% (95%CI: 15-54%), respectively. Chemorefractory disease at transplant was associated with a worse 18-month RI/POD (70% vs 18%, p=<0.01) and a markedly reduced PFS (9% vs 57%, p=0.04) and OS (53% vs 78%, p=<0.01) (Figure 1). Survival outcomes were similar between marrow-derived and peripheral blood graft source cohorts. Conclusions: HaploHCT is a feasible and effective strategy in patients with relapsed/refractory high-risk multiple myeloma. Chemorefractory disease at transplant was the only prognostic factor associated with a significant reduced RI/POD, PFS and OS.

e19513 Background: Although there is much to be optimistic about in the multiple myeloma community as the approval of new therapies and regimen-combinations for relapsed refractory disease continues to grow, determining the best option for a patient can be complicated. Both carfilzomib- (C) and daratumumab- (D) based regimens have demonstrated superior efficacy in this setting, but there is a paucity of data supporting which should be selected first, and if regimen sequence influences outcomes. The aim of this study is to describe sequencing patterns in the era of these newer agents and to determine if there is a difference in outcomes for patients with RRMM who received one of the following treatment sequences: C-regimen with a D-regimen given immediately prior (DC); C-regimen without any prior D (C only); D-regimen with a C-regimen given immediately prior (CD); or D-regimen without any prior C (D only). Methods: This is a retrospective analysis of patients with RRMM consecutively treated at Moffitt Cancer Center between 1/1/2015 and 6/25/18. Response to therapy was assessed using the International Myeloma Working Group (IMWG) criteria. Progression-free survival (PFS) was measured in days from the start of therapy to progression. Time to response (TTR) was measured in days from the start of therapy to first response. Results: 132 patients with RRMM who received 1-3 prior lines of therapy with at least one line of therapy containing either C or D were identified. Overall, the majority of patients were treated with C only (n = 101), 10 received DC, 31 received D only, and 35 received CD. In patients that received C only, partial response (PR) was achieved in 38%, very good partial response (VGPR) was 20%, and stringent complete response (sCR) was 2%. In patients that received DC, PR was 20% and VGPR was 10%; no patient achieved a sCR. Of the patients that received D only, PR was 29%, VGPR was 10%, and sCR was 3%. In patients that received CD, PR was 31% and VGPR was 26%; no patient achieved sCR. Median PFS in patients who received C only, DC, D only, and CD was 117 days, 126 days, 104 days, and 190 days, respectively. TTR in patients who received C only, DC, D only, and CD was 82 days, 39 days, 98 days, and 88 days, respectively. Conclusions: The data suggests that RRMM patients who receive either CD or DC appear to have a PFS advantage over those patients who did not.

e20509 Background: We evaluated outcomes of patients with multiple myeloma (MM) ≥ 70 years who were seen for Autologous Stem Cell Transplant (ASCT) consult, based on whether they underwent transplant vs. non-transplant treatment. Methods: 138 patients with MM ≥ 70 years (median 71, range 70-78) were evaluated in the BMT clinic from 1/2010 to 11/2019 for a transplant consult. Results: Of the 138 patients, 53 proceeded to ASCT. ASCT was not pursued in 85 patients despite most (79%) being eligible for transplant. Reasons for deferring ASCT in eligible patients included patient preference (48%, n = 32) and physician preference (52%, n = 35). 68 patients were seen during first-line therapy, of which 29 underwent upfront transplant. The remainder were seen at second-line or beyond. There was no difference in baseline characteristics among the 113 patients with available follow-up (ASCT = 53, non-ASCT = 60), including median age (71 vs. 72 years, p = 0.4), high-risk cytogenetics (41% vs. 31%, p = 0.4), high-risk HCT-CI (32% vs. 20% p = 0.2), and ISS stage III (34% vs. 27%, p = 0.6). In the 53 patients who underwent transplant, conditioning melphalan dose was 200 mg/m2 (75%, n = 40) and 140 mg/m2 (25%, n = 13). Day 100 transplant related mortality was 0% (n = 0). Progression-free survival (PFS) and overall survival (OS) were compared in patients who were seen for consultation within 1 year of diagnosis (n = 80). With a median follow-up of 27 months, median PFS amongst patients ≥ 70 years undergoing ASCT (n = 39) was 47 months compared to 34 months in the non-ASCT (n = 41) group, p = 0.006. Median OS was not reached in either group. Estimated 5-years OS was 76% in the ASCT group and 82% in the non-ASCT group (p = 0.6). There was no difference in PFS of patients ≥ 70 undergoing ASCT compared to a cotemporaneous cohort of patients < 70 (n = 639) from our institution (47 vs. 57 months, p = 0.3). Conclusions: Selected patients ≥ 70 years with MM undergoing ASCT have better PFS compared to patients with similar characteristics who do not undergo ASCT. ASCT is safe in this older population and outcomes were similar compared to younger patients. [Table: see text]

Abstract Abstract 595 Multiple myeloma is a malignancy of terminally differentiated plasma cells in which the malignant plasma cell clone usually produces a single abnormal unique monoclonal antibody with a constant isotype and light chain-restricted paraprotein. Recently, the occurrence of oligoclonal and monoclonal bands (OB/MB) not related to the original clone has been reported in patients with multiple myeloma who undergo autologous stem cell transplant (ASCT) and/or receive treatment with novel agents. Based on this data, the aim of our study was to assess the impact of monoclonal (MB) and oligoclonal bands (OB) occurrence on overall survival (OS) and progression-free survival (PFS) for MM patients undergoing single ASCT at Princess Margaret Hospital (PMH). Patient and Methods: All consecutive patients with documented MM undergoing single ASCT at PMH from 01/00 to 12/07 were evaluated. Oligoclonal banding (OB) was defined as the development of two or more concurrent monoclonal-type bands on the serum electrophoretic pattern, with either a different heavy or light chain component from the original M-protein band at day+100 post-ASCT. A new monoclonal band (MB) was defined as a heavy and/or light chain immunoglobulin distinct from the initially diagnosed MM. All cases with OB/MB in our series fulfilled the criteria of secondary monoclonal gammopathy of undetermined significance (MGUS). Multivariate analysis was performed with the Cox proportional hazard model. All analyses were performed using the SPSS 13.0 software. Results: Between January 2000 and December 2007, 788 patients were identified. Clinical and laboratory characteristics are listed in Table 1 Ninety-six patients (12.1%) developed OB/MB at 3 months from ASCT: 32 patients (33.3%) had OB, and 64 patients (66.7%) had a new MB. The median duration of the OB/MB was 12 months (range 4–52 months). OB and MB emerged after ASCT in 14% (60/409) of patients receiving VAD, 7.0% of patients receiving bortezomib (6/86) and 8.6% of patients receiving thalidomide (6/69) containing regimens as induction therapy. Thirty-seven (38%) patients with subsequent development of an OB/MB had achieved ≥VGPR after induction and this rate improved to 79% (76/96) at day +100 post-ASCT. Patients who did not develop OB/MB had a ≥VGPR rate of 28% and 58% after induction and day+100 post-ASCT, representing a lower rate than patients with OB/MB (p=0.07 and 0.002, respectively). At the time of this analysis, 65 (67.7%) of the cohort patients who developed OB/MB are alive and 68 have already progressed (70.8%). Median overall survival for patients who did not develop OB/MB at day+100 post ASCT was 74.5 months compared to 115.5 months for those who developed OB/MB (p=0.0098). Multivariate analysis shows developing of OB/MB as an independent prognostic factor for OS and PFS (p=0.006 and 0.021, respectively). (Fig1a-b) The duration of the OB/MB did not affect OS and PFS. In conclusion, OB/MB occurrence is an important prognostic factor in MM patients who undergo ASCT, the biological significance and its impact on clinical outcomes should be prospectively validated.
