Abstract Backround: Arsenic trioxide (ATO), an active agent against multiple myeloma, has been shown to be synergistic with melphalan both in vitro and in vivo. We conducted a phase I/II trial to determine the safety and efficacy of a combination of arsenic trioxide, melphalan and ascorbic acid (AA) as prepaprative regimen in patients undergoing high-dose therapy (HDT) and autologous hematopoietic progenitor cell transplantation (AHPCT) for multiple myeloma (MM). We also assessed the impact ATO levels on melphalan pharmacokinetics (PK), engraftment and toxicity. Methods: Twenty-five patients with secretory myeloma (11 females, 14 males median age: 53, range: 49 – 69) were treated b/w 4/04 and 1/05. All patient received melphalan 100 mg/m2 IV on days -4 and -3 and AA 1000 mg/day IV on days −9 to −3. Patients were randomized to 3 arms; no ATO (arm 1), ATO 0.15 mg/kg IV on days −9 to −3 (arm 2) and ATO 0.25 mg/kg IV on days −9 to −3 (arm 3). Seven patients had a prior autograft. Median CD34 cells dose infused was 4.4 x 106/kg (range 2.3–10.9). Results: Patients were evenly matched except for a high median β2m level (3.6 vs. 2.4 in arms 1 and 2, p=0.04) in arm 3. With a median F/U of 7.1 months post autograft, no dose-limiting toxicity or non-relapse mortality was seen. Median ATO level on day 0 in arms 1, 2 and 3 were 0.2, 26.3 and 46.2 ng/ml, respectively. Toxicity was limited grade I or II nausea, vomitting and diarrhea. Median time to neutrophil engraftment (ANC >500/dl) was 9 days. There were no engraftment failures or delays in the ATO arms. Response rates (RR) are shown in Table 1. With a median F/U of 7.1 months (range, 6.4 – 8.9 months), the progression-free survival (PFS) and overall survival (OS) are as shown in Figure 1. There was no significant difference in RR, PFS or OS between the 3 arms. Melphalan PK was not altered by ATO pretreatment. Conclusions: Arsenic trioxide, given in combination with melphalan and ascorbic acid as preparative regimen, is safe and well tolerated. A longer follow up is needed to determine the impact of this combination on survival.

Abstract Backround: Arsenic trioxide (ATO) has been shown to be synergistic with melphalan both in vitro and in vivo. We conducted a phase I/II trial to determine the safety and efficacy of a combination of arsenic trioxide, melphalan and ascorbic acid (AA) as preparative regimen in patients undergoing high-dose therapy (HDT) and autologous hematopoietic progenitor cell transplantation for multiple myeloma (MM). We also assessed the impact ATO levels on melphalan pharmacokinetics (PK), engraftment and toxicity. Methods: Forty-eight patients with secretory myeloma (23 females, 25 males; median age: 54, range: 3570) were treated between 4/04 and 8/05. All patient received melphalan 100 mg/m2 IV on days -4 and -3 and AA 1000 mg/day IV on days -9 to -3. Patients were randomized to 3 arms; no ATO (arm 1), ATO 0.15 mg/kg IV on days -9 to -3 (arm 2) and ATO 0.25 mg/kg IV on days -9 to -3 (arm 3). Twelve patients had disease progression or relapse after a prior autograft. Median CD34 cells dose infused was 4.5 x 106/kg (range 2.3–10.9). Results: Patients in all 3 arms were evenly matched. With a median F/U of 14.0 months (range 6–25) post autograft, no dose-limiting toxicity or non-relapse mortality was seen. Toxicity was limited to grade I or II nausea, vomiting and diarrhea. Median ATO levels on day 0 in arms 1, 2 and 3 were 0.2, 26.3 and 46.2 ng/ml, respectively. Melphalan PK was not altered by ATO pretreatment. Median time to neutrophil engraftment (ANC >500/ dl) was 9 days. There were no engraftment failures or delays in the ATO arms. CR rate for the entire group was 23%, and total response rate (CR + PR) was 75%. 1-year Progression-free survival (PFS) and overall survival (OS) were 75% and 95%, respectively. There was no significant difference in CR, RR, PFS or OS between the 3 arms (p = 0.9, 0.9, 0.4 and 0.6, respectively). A prior autologous transplant (p = 0.02) and abnormal cytogenetics at transplant (p = 0.04) were associated with a significantly shorter remission. Conclusions: ATO + melphalan + ascorbic acid is a safe, effective and well tolerated preparative regimen for patients with multiple myeloma undergoing an autotransplant. A longer follow up is needed to assess the impact of ATO on progression-free and overall survival.

Abstract Introduction : To date, the ELN recommendation and NCCN guidelines are the principle mile stones to follow up the treatment response and to make the decision of TKIs switching. However, in real life practice, many factors influence changing the real switching date from the date had an indication. This study aims to analyze the impact of early switching to second line TKI, nilotinib, in real life practice, for the CML patients who failed, had sub-optimal response or were intolerant to imatinib. Methods : This prospective study was conducted through 7 medical centers in Thailand between 1st of September 2009 and 31st of August 2011. Adult CML patients of age ≥ 18 years old, in chronic and accelerated phase, who had failure, suboptimal response or intolerance to imatinib, based on ELN 2009 guideline, were included and were eligible with nilotinib 400 mg twice daily. Prospective data collection for 24 months of each patient was performed. The main objective was to identify the impact of early switching to nilotinib on major molecular response (MMR). The other objectives were to observe the efficacy of nilotinib including overall survival, progression free survival and the safety. The survival results were presented as Kaplan-Meier survival curves. For the comparison of the treatment groups, the Kaplan-Meier estimator with the corresponding log-rank test for equality of survivor functions across treatment group was applied. Results : The final 108 cases were analysed. The median age was 47 (17-79) years with the proportion of male to female of 1.4:1 respectively. The median duration of the prior imatinib treatment was 18 months (2-142 months). The median duration between the date of indication and the date of real switching was 3.1 months (0-62.8 months) with 50% changing less than 3 months, 26.9% between 3 months and 12 months, and 23.1% changing longer than 12 months. The indication of switching included 63.6% failure to imatinib, 29% intolerance to imatinib and 7.4% suboptimal to imatinib. On the nilotinib switching, 70.4% completed 24 months follow-up, and 29.6% discontinued treatment mostly because of unsatisfactory results or adverse events. Evaluation was made every 3 months based on 2009 ELN recommendation. At 3 months, 57%, 20%, and 8% of the patients achieved CHR, CCyR and MMR, respectively. Those who did not achieve CHR at 3 months never achieved MMR, while 86 % of those who achieved CCyR at 3 months achieved MMR. All CML achieving MMR at 3 months had sustained MMR throughout the study period (24 months). Imatinib suboptimal response had better outcome than imatinib failure and imatinib intolerance groups. A preliminary analysis of BCR-ABL mutation was performed on 90 cases, and mutations were found on 21 cases. Two of them were T315I which were excluded from the study. The cases with mutation had poorer response to treatment than those without mutation. There was one case with initial G250E mutation developing T315I mutation after treatment with nilotinib. At 24 months, one case progressed to accelerated phase and 3 cases progressed to blastic transformation. The 2-year overall survival and 2-year progression-free survival and were 98.9% and 96.9% (figure 1 and 2), respectively. The interquatile analysis was done to identify the groups of cumulative MMR according to the duration between the date of indication and the date of real switching to nilotinib. The patients who switched to nilotinib within 12 months after date of indication could have a greater chance to achieved MMR than those who switched treatment later than 12 months (p(log-rank) = 0.002) (figure 3). Skin rash, musculoskeletal pain, and infection were the three most common non-hematologic adverse events, However, most of them were grade 1-2, except for 4 cases with grade 3-4 infections. Grade 3-4 hematologic adverse events included thrombocytopenia (12%), neutropenia (11%), anemia (5%) and leucopenia (4%), and most of them were manageable. Although biochemical abnormalities were commonly found, most of them were mild. Conclusions : Nilotinib, as a second line treatment showed excellent efficacy and tolerability. Indication for nilotinib treatment, initial mutation status and depth of response at 3 months after treatment can predict outcomes of the patients. However, the patients will have a greater chance to achieve MMR if they switched to nilotinib within 12 months after the date of indication for changing.

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.

e20001 Background: Multiple Myeloma (MM) is a neoplasm of the post-germinal center, terminally differentiated B-cells. MM accounts for 1% of all types of cancer and 10% for all hematologic malignancies. Chronic hepatitis C virus (HCV) is an infection that affects over 71 million patients worldwide. Cytotoxic agents and immunosuppressive therapy as steroids are the main line of therapy in lymphoid malignancies, but these drugs may exacerbate chronic viral hepatitis and cause uncontrolled replication of hepatitis viruses. The impact of HCV infection on MM patients remains unclear. Objective: To assess the impact of HCV infection on the prognosis and management of MM patients. Methods: A 10-year retrospective study of MM patients was conducted at Cairo University Clinical Oncology Department from January 2009 to April 2019. Results: During this time, 150 patients were diagnosed with MM, 109 (72.7%) were HCV negative, 24 (16%) were HCV positive, and 17 (11.3%) with unknown HCV status. The median age was 51 and 54 years for HCV negative and positive groups respectively, with a statistically insignificant difference (p-value > 0.2). In the multivariate analysis, HCV infection was not an independent factor related to overall survival (OS), however age, creatinine and hemoglobin levels correlated significantly with OS (p < 0.009, 0.008, 0.031 respectively). The median OS for the HCV negative group was 31.11 months (95% CI: 22.62 - 39.61) compared to 37.66 months (95% CI: 7.19 - 68.13) for the HCV positive group. The median progression-free survival (PFS) for all patients was 18.9 months, for HCV positive patients was 15.36 months (95% CI: 13.18 – 17.54), and for HCV negative patients was 20.49 months (95% CI: 14.13 – 26.85). Age below 60 years and creatinine level less than 2 mg/dL were statistically significant for favorable disease-free survival (DFS) (p < 0.030, 0.034 respectively). Conclusions: Age, creatinine and hemoglobin levels are significant prognostic factors in MM but HCV status doesn’t affect the overall survival or progression-free survival. HCV infection should not contraindicate MM therapy.

Abstract Background: For a long time, multiple myeloma has been a disease with a poor outcome. High dose (melphalan) chemotherapy followed by autologous stem cell transplantation has been reported to improve the overall and progression-free survival of these patients. Objective: To determine the survival of multiple myeloma patients treated with conventional chemotherapy and compare it with that of patients treated with high-dose chemotherapy followed by autologous peripheral blood stem cell transplantation. Design/Methods: 83 myeloma patients treated at a single institution were included in this retrospective study. They were divided into two groups: one group of patients who were received high-dose chemotherapy followed by autologous peripheral blood stem cell transplantation (n=42) and one group of patients who only received conventional chemotherapy and were eventually also treated with thalidomide and/or corticosteroids (n=41). The distribution of the stages of the disease according to Salmon and Durie were similar in both groups of patients. For both groups, the overall and progression-free survival was calculated. Results: In the general analysis, myeloma patients who underwent an autologous transplant had a significantly longer overall survival (58.8 vs. 52.2 months, p=0.036) and progression-free survival (39.6 vs. 11.8 months, p &lt; 0.001) in comparison with the conventional chemotherapy group. If analysis was restricted to those patients who were transplanted as a first-line treatment, there was no significant difference in overall survival in comparison with conventional chemotherapy (51.8 vs. 52.2 months, p= 0.422); progression-free survival was significantly better in the first-line transplant arm as compared to the conventional chemotherapy arm (35.4 vs. 11.8 months, p= 0.003). As the median age in the transplant arm was significantly lower than in the conventional chemotherapy arm, we also performed a sub-analysis of patients who were between 60 and 70 years of age at diagnosis; there was no significant difference in overall survival between the two groups (60.7 vs. 69.5 months, p= 0.656), while the progression-free survival was again better in the autologous transplant group as compared to the conventional chemotherapy group (41.0 vs. 8.4 months, p= 0.020). Conclusion: High-dose chemotherapy and autologous stem cell transplantation in the treatment of myeloma is associated with improved progression-free survival and in the general analysis, with improved overall survival. The overall survival of patients who were only treated with conventional chemotherapy is somewhat higher (more than 4 years) as compared to that of historical controls (2–3 years).

Abstract Abstract 3400 Poster Board III-288 To analyse the impact of complete response (CR), near CR (nCR) and very good partial response (VGPR) before and after first high-dose therapy (HDT) followed by autologous stem cell transplantation (ASCT) on overall survival (OS) and progression-free survival (PFS), we evaluated all patients with multiple myeloma (MM) who underwent an ASCT in frontline treatment at our centre. The transplantations were performed between June 1992 and February 2009 giving a minimum follow up of 5 months after ASCT. The retrospective analysis included a total of 994 patients (579 males and 415 females) with a median age of 58 years at time of first ASCT (range 25 - 76 years). Median follow-up after first ASCT was 5.8 years. All patients suffered from symptomatic MM. Before induction treatment 48%, 31% and 21% of patients were in ISS-stage I, II and III, respectively. The following induction regimes were applied prior to HDT: VAD (n=683), TAD (n=74), PAD (n=64), and other regimes (n= 173). The patients were treated with HDT once (n= 460), twice (n=437) or thrice (n=97). 91 patients received an allogeneic SCT, 30 of these before first progression after ASCT. These were censored for PFS at time of allogeneic SCT. Maintenance therapy (interferon n=332, thalidomide n=203, bortezomib n=48 or others n=13) was administered in 596 patients. Overall survival and progression-free survival were calculated from the time of first ASCT. The median OS time was 5.7 years and the median PFS was 2.2 years. Log-rank test, univariate and multivariate Cox PH regression as well as landmark analyses were utilized to assess the prognostic impact of response. We analysed the effect of achievement of CR, of nCR or CR and of VGPR or CR or nCR before and after HDT, respectively. Achieving CR or nCR is a highly significant prognostic factor for PFS and OS before (p<0.001 and p=0.01, respectively) and after first HDT (both p<0.001). The group including VGPR showed superior outcome when assessed after HDT, driven by the effect of CR/nCR. When adjusting for the effect of age, beta-2 microglobulin before ASCT, albumin before ASCT, new drugs before ASCT (thalidomide and bortezomib; yes/no), second ASCT within 9 months (yes/no), maintenance therapy (yes/no), and date of first ASCT, achieving CR or nCR remained a significant prognostic factor (PFS after ASCT: HR=0.66 [0.54;0.80], p<0.001; OS after ASCT: HR=0.65 [0.51;0.83], p=0.001). In addition, we analyzed the effect of duration of response compared to response achievement per se. Patients who sustained their remission (overall response = PR and better) at 3 yrs after first ASCT had a favourable prognosis with respect to OS compared to patients losing remission. Conclusion: In our single-center cohort achieving CR or nCR before and after first HDT is highly prognostic for PFS and OS in MM. Sustained duration of response is also associated with an improved prognosis (3 years landmark analysis). At our centre we recommend that patients not achieving at least an nCR should be treated with a second cycle of HDT. Disclosures: No relevant conflicts of interest to declare.

AbstractIn multiple myeloma (MM), the impact of complete response (CR) could be shown only after introduction of high-dose therapy plus autologous stem cell transplantation (ASCT). In the context of ASCT, achieving CR (negative immunofixation and normal bone marrow) or at least very good partial response is associated with longer progression-free survival and in most studies longer survival. With novel agents, high CR rates are achieved and this prognostic impact of CR is being shown as well, both in relapsed and in newly diagnosed MM. However the benefit of CR achievement depends on the type of treatment and is not identical for all patients. In elderly patients, treatments inducing more CR may be more toxic. Although CR achievement is necessary in patients with poor-risk disease, it might not be as critical for long survival in more indolent MM. CR achievement is not the only objective of treatment because it is possible to further improve the depth of response and the outcome by continuing treatment after CR achievement. Finally, there are several levels of CR and in the future it will be necessary to confirm the prognostic impact of immunophenotypic or molecular CR or of CR defined by imaging procedures.

Abstract Introduction Preclinical and clinical data suggest that bortezomib in combination with high-dose melphalan (Bor-HDM) provides with a synergistic effect able to improve the quality of response for MM patients undergoing auto-SCT. In the present study, we aimed to assess the impact of Bor-HDM conditioning on ORR, and MRD negativity for MM patients undergoing single auto-SCT at our Institution. Methods All consecutive patients who underwent single auto-SCT at Tom Baker Cancer Center (TBCC) from 01/2004 to 06/2015 using Bor-HDM or HDM as conditioning regimen were evaluated. Definitions of response and progression were used according to the EBMT modified criteria and a category of very good partial response (VGPR) was added. MRD negativity was assessed by multiparameter flow cytometry. All patients received induction chemotherapy before undergoing auto-SCT. Bortezomib was administered intravenously at 1-1.3 mg/m2 on days −5, −2, 1, and 4, while melphalan was given at 200 mg/m2 on day −1. A p value of <0.05 was considered significant. Survival curves were constructed according to the Kaplan-Meier method and compared using the log rank test. Results Two-hundred and fifty-eight consecutive patients receiving Bor-HDM or HDM alone were evaluated. A total of 85 patients received Bor-HDM conditioning and 173 received HDM. Clinical characteristics and chemotherapy induction regimens are listed in Table 1. At day-100 post auto-SCT a ³VGPR was seen in 83.3% in the Bor-HDM group compared to 67.6% for HDM patients. The CR/nCR rate was higher in the Bor-HDM group (47.6% vs 23.6%) as well as MRD negativity assessed by flow cytometry (30.9% vs 9.7%, p=0.0001). Median OS in the Bor-HDM group was NR compared to 95 months for HDM alone (p=0.572), while median PFS was 39.3 months for Bor-HDM compared to 27 months for HDM (p=0.1). Median OS was shorter in the HR cytogenetic group regardless of the type of conditioning regimen employed (39 months vs NR for SR cytogenetics). In addition, patients who achieved MRD negativity, exhibited a longer OS (NR vs 78 months, p=0.007). Transplant-related mortality (TRM) was similar between both groups (p0.5). In conclusion, Bor-HDM is a safe and efficacious conditioning regimen able to increase the nCR/CR and MRD negativity rates compared to HDM. Further studies are warranted to explore this regimen, especially when other upfront therapies are employed, with special view on the high-risk MM patients where response rates are good but sustainability remains an issue.

The Impact

Abstract The chromosomal abnormalities of del(13), t(4;14), and del(17p) are associated with poor progression-free survival (PFS) and shorter overall survival (OS) in newly diagnosed multiple myeloma (MM) treated with traditional chemotherapy. In patients with relapsed or refractory MM, a recent study demonstrated that lenalidomide (Revlimid®) can overcome poor prognosis conferred by del13q and t(4;14) but not del17p13 (Bahlis et al 2007). Here, we performed a retrospective analysis of medical records obtained from 49 clinical centers participating in the French Autorisation Temporaire d’Utilisation program. Patients with relapsed or refractory MM received dexamethasone 40 mg orally (days 1–4; 9–12 and 17–20 for 4 cycles, then days 1–4 beginning with cycle 5) and lenalidomide 25 mg orally on days 1–21 of a 28 day cycle. CD138-purified plasma cells were analyzed with fluorescent in-situ hybridization (FISH) for del(13), t(4;14), and del(17p) at diagnosis. Response and disease progression endpoints were evaluated using the European Group for Blood and Marrow Transplantation criteria. A multivariate analysis was performed to assess the impact of the following 7 variables on outcomes: any chromosomal change, prior bortezomib use, prior thalidomide use, prior transplant, progression on thalidomide, age, and number of lines of previous therapy. In total, 207 patients were included in the analysis; the median number of treatment cycles was 5 (range, 1–22). Most patients in the current study had received prior thalidomide (87%) or bortezomib (81%). The overall response rate (ORR) was 59%, including 7% complete response and 14% very good partial response. Median progression-free survival (PFS) and overall survival (OS) were 9.6 months and 15.1 months, respectively. These values are comparable to the recently published phase III trials (Weber et al., 2007; Dimopoulos et al., 2007), despite the higher median number of prior therapies in this analysis (5 vs. 3). Overall, 41% of patients had del(13), 14% had t(4;14) and 5% had del(17p). The ORR was significantly lower, and PFS and OS significantly shorter, in patients with del(13) compared with patients without del(13) (ORR: 43% vs. 71%, P<0.001; PFS: 5.0 months vs. 12.5 months, P<0.0001; OS: 10.4 months vs. 17.4 months, P=0.001). A similar pattern was observed in patients with t(4;14) versus patients without t(4:14) (ORR 39% vs. 62%, p=0.04; PFS 5.5 months vs. 10.6 months, p<0.01; OS 9.4 months vs. 15.4 months, p=0.005). Multivariate analysis identified hemoglobin (<10 g/dL), progression on thalidomide, and del(13) as independent predictors of reduced PFS (Table). There was a trend towards reduced PFS with prior bortezomib use and number of prior therapies. Age, sex, prior transplant, prior thalidomide use, and t(4;14) did not affect PFS. The results from the analysis indicate that del(13), progression on thalidomide, and hemoglobin levels ≥10 g/dL have a significant impact on outcomes in heavily pre-treated patients with relapsed or refractory MM. Randomized trials are needed to further assess these findings.

Abstract Objective The aim of this study is to explore the role of tumor associated macrophages (TAMs) in the prognosis, early treatment response of multiple myeloma and to investigate the role of TAMs on the proliferation, apoptosis£¬oncogene expression and chemotaxis of myeloma cells. Methods 1 In vivo we retrospectively collected and analyzed 240 patients initially diagnosed wih multiple myeloma and their bone marrow biopsy tissue from Jan, 2009 to June, 2014 in West China Hospital, Sichuan University, China. All the patients enrolled in this study were followed up till April, 2015. We observed and quantified the involvement of macrophage (M¦µ), classic activated macrophage (M1 M¦µ) and alternatively activated macrophage (M2 M¦µ) in bone marrow by immunohistochemical staining of anti-CD68 monoclonal antibody, anti-iNOS monoclonal antibody and anti-CD163 monoclonal antibody, respectively. We analyzed the relation between macrophage involvement with International Staging System (ISS) and the clinical response as well. The effect of different type macrophage involvement on prognosis, progression-free survival and overall survival were estimated. Time-to-event data were analyzed with the Kaplan-Meier method, and the differences were calculated using the Log-rank and Breslow tests. Cox proportional-hazards models were used to estimate hazard ratios and 95% confidence intervals for the main comparisons. 2 In vitro we induced human peripheral blood mononuclear cell£¨PBMC£© and human monocytic THP-1 cells to M2 macrophages with M-CSF or PMA in the presence of IL-4/13 in vitro. Macrophages were identified by morphology and flow cytometry. Two myeloma cell lines (RPMI 8226 and U266) were cocultured with M2 macrophages by using a transwell system. We measured myeloma cells proliferation through CCK-8 method and the pro-inflammatory cytokines expression (TNF-¦Á and IL-6) by ELISA. Real time PCR was applied to measure chemokines (CCL2 and CCL3), chemokine receptors (CCR2, CCR1, CCR5), vascular endothelial growth factor (VEGFA, VEGFB and VEGFC), VEGF receptors (VEGFR1-3), proto-oncogene serine/threonine-protein kinase Pim (PIM1-3). In addition, flow cytometry was used to analyze the apoptosis of myeloma cells induced by dexamethasone. Results 1 patients with high M2 macrophage involvement (>40/hp) in bone marrow showed poorer response (including complete response and partial response after 3 cycles of chemotherapy) to Dexamethasone-containing regimen (23.9% versus 73%, P=5x10-13). On the contrary, the patients with high M1 macrophage involvement demonstrated much better response to regimen than low M1 macrophage (69.6 versus 40.6%, P=5x10-5). 2 Both progression-free survival and overall survival were significantly shorter with high M2 macrophage involvement than low involvement (median progression-free survival, 12.9 months vs. 39 months; hazard ratio for progression, 1.77, 95% confidence interval [CI], 1.14 to 2.74; P=0.01; and overall survival, 4.9 months vs. 59.2 months; hazard ratio for death, 2.63; 95% CI, 1.75 to 3.95; P<0.001). 3 In vitro M2 macrophage stimulate myeloma cell proliferation. 4 In vitro M2 macrophage protect myeloma cells from dexamethasone induced apoptosis. 5 In vitro M2 macrophage promote myeloma cells secreting higher level of IL-6, TNF-¦Á and higher expression of CCL2, CCL3, CCR2, CCR5, VEGFA, VEGFR-1,-2, PIM-1, PIM-2 compared with the non-macrophage coculture system. Conclusion TAMs are associated with early clinical response and prognosis. Notably, M2 macrophages involvement has been shown strongly negatively associated with progression-free survival and overall survival. M2 macrophages promote myeloma cells proliferation and protect from apoptosis through a very complex mechanism involving pro-inflammatory cytokines IL-6 and TNF-¦Á, chemokines and related receptors such as CCL2, CCL3, CCR2 and CCR3, VEGF, VEGFR and PIM1, PIM2.
