Abstract Background: Abnormally increased tumor associated neovasculature plays an important role in tumor progression in solid tumors and hematological malignancies. In multiple myeloma (MM) bone marrow angiogenesis, measured in terms of microvessel density (MVD), has prognostic value, and appear to increase with disease progression from monoclonal gammopathy of undetermined significance to relapsed MM. We have shown that MVD has prognostic value in patients with newly diagnosed MM including patients undergoing upfront high dose therapy and stem cell transplantation, but comparison with other known prognostic factors has been limited by sample size. It is also not known whether the MVD adds prognostic value once the recently described International Staging System (ISS) is applied. The goal of this study was to determine the prognostic effect of bone marrow MVD in newly diagnosed MM relative to the ISS and other known prognostic factors. Methods: We studied 400 patients with newly diagnosed MM seen at the Mayo Clinic between March of 1988 and December 2001. Sections from bone marrow biopsy blocks from the time of initial diagnosis were studied by immunohistochemistry using antibodies against CD34 antigen to high light the endothelial cells. Under low power (100X); three areas with maximum number of microvessels (hotspots) were identified. Each of these areas was further studied at 400X magnification and the number of microvessels per high power field counted. The average of the three readings was taken as the MVD for the sample. In addition, the samples were graded as low, intermediate or high by using a visual estimate as previously described. Additional clinical data was extracted from medical records. Some of the patients have been included in previous studies related to angiogenesis. Results: A total of 400 patients in whom a bone marrow biopsy from within 30 days of diagnosis was available were studied. The pts were followed for a median of 37 months (Range: 1 month to 16.5 years) and 318 pts (80%) had died at the time of this analysis. The median MVD for the entire group was 14.7 (Range 0–168). The median overall survival for the three groups according to the MVD grade was lower for the high grade group (31.9 months) compared to the intermediate grade group (37.2 months) and the low grade group (not reached); P <0.029, log rank test. We examined this group of patients for other factors prognostic for overall survival. Factors significant on univariate analysis included ISS stage, platelet count (<150 vs. >= 150 X 106/L), and plasma cell labeling index (<1 vs >=1). In a multivariate analysis using these variables and MVD as a continuous variable, high MVD and the ISS staging system were significantly associated with poorer survival (Table). Conclusion: In this large group of pts with newly diagnosed MM, we confirm the prognostic value of increased bone marrow angiogenesis. We examined the MVD as a continuous variable in the multivariate analysis for a closer evaluation of this measure in this comparison. More importantly, the prognostic value appears to be independent of the ISS and other major prognostic factors. The resultsof this study reinforces the biological relevance of this finding in MM. HR 95% CI P value MVD 1.006 (1.001, 1.011) 0.0279 ISS Stage I 0.37 (0.25, 0.56) <0.001 ISS Stage II 0.58 (0.41, 0.83) 0.0025

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 4866 Background Multiple myeloma (MM) is an incurable malignant disease, characterized by increased angiogenesis in the bone marrow (BM) microenvironment and aberrant BM metabolism. Matrix metalloproteinases (MMP) are a family of zinc-dependent endopeptidases implicated in tumour progression, invasion, metastasis and angiogenesis, via proteolytic degradation of extracellular matrix. MMPs are inhibited by tissue inhibitors of metalloproteinase (TIMP). Although recent studies have implicated MMP 9 in MM bone disease, little is known about the role of the TIMPs. Objectives a) to compare levels of sRANKL, OPG, MMP-2, MMP-9, TIMP-1, TIMP-2, VEGF, bFGF, microvessel density (MVD) between newly diagnosed MM patients and healthy controls; b) to determine the association of these molecules with disease progression, bone disease and neoangiogenesis and c) to evaluate the impact of these variables on survival. Patients and Methods As of July 2009 38 newly diagnosed and untreated multiple myeloma patients were enrolled in the study. The median age was 61years-old (range 39-91) with 24 (63%) males. Patients were diagnosed and categorized according The International Myeloma Working Group criteria and ISS, respectively. Bone involvement was graded according to standard X-ray: patients with no lesions, or with one/ two bones involved or diffuse osteoporosis were classified as low score, whereas patients with lesions in more than two bones or presence of bone fracture were classified as high score. MMP-2 and MMP-9 were determined by PAGE gelatin zymography from plasma as previously described. MMP-9, TIMP-1 and TIMP-2, OPG and sRANKL concentrations were measured by ELISA. The levels of VEGF, bFGF were obtained using cytometric bead array. Ten healthy volunteers were used as controls. Bone marrow MVD measured in hotspots was evaluated in 26 out of 38 patients at diagnosis and 15 patients with Hodgkin Lymphoma stage IA and IIA (used as controls) by staining immunohistochemically for CD34. Comparisons among groups were analyzed by ANOVA and the correlation by the Spearman's correlation coefficient. Cox regression were performed for overall survival (OS) analysis. Results Patients with MM had elevated TIMP-1, TIMP-2 and OPG values compared with controls. No significant difference was found between plasma sRANKL, pro-MMP2, pro-MMP9 and MMP-9 levels. We found that plasma TIMP-1 levels correlated positively with bFGF, VEGF, MVD, beta-2 microglobulin (B2M) and OPG (r: 0.514, p=0,001, r: 0.350, p=0,031; r: 0.610, p<0.0001; r: 0.760, p<0.0001 and r: 0.701, p<0.0001, respectively) and TIMP-2 levels with bFGF, DMV, B2M and OPG (r: 0.512, p=0.002; r: 0.595, p<0.0001; r: 0.587, p<0.0001 and r: 0.552, p<0.0001, respectively). TIMP-1 and TIMP-2 levels correlated with the ISS stage (p<0.0001, p=0.006, respectively). The only variables that correlated with clinical bone disease staging were hemoglobin, B2M and albumin levels, whereas TIMP-1, TIMP-2, bFGF, VEGF and OPG correlated with DMV. On the univariate analyses, age, gender, proMMP2, TIMP-1, TIMP-2, creatinine, B2M and MVD were significantly associated with overall survival. In Cox regression model, TIMP-1, TIMP-2 and B2M levels remained to be significantly associated with OS. In conclusion, our results suggest that TIMP-1 and TIMP-2 levels are strongly associated with neoangiogenesis and are independent prognostic factors in MM. Disclosures No relevant conflicts of interest to declare.

Abstract Complete response (CR) is an important objective of autologous stem-cell transplantation (ASCT) in multiple myeloma (MM). In comparison with conventional induction treatments, newer combinations of novel agents may effect increased rates of CR and near CR (nCR), a benefit potentially translating into even higher frequencies of CR/nCR after ASCT and improved clinical outcome. We designed a phase III study to detect an increase in CR+nCR rates from 10–15% with conventional Thalidomide-Dexamethasone (TD) to 20–30% with Velcade added to TD (VTD) in newly diagnosed MM. Both TD and VTD were given as three 21-day cycles in preparation for double ASCT. In the present analysis, CR+nCR rates by the two induction treatments were examined in relationship to baseline prognostic variables in 399 evaluable pts aged ≤65 years, of whom 199 randomized to VTD and 200 to TD. All analyses were intent to treat. In comparison with TD, VTD effected higher rates of CR+nCR (12% vs 33%, P&lt;0.001) and of ≥very good partial response (VGPR) (30% vs 61%, P&lt;0.001). By univariate analysis, superiority of VTD to TD was maintained across all sub-group analyses according to standard prognostic factors, including β2-m, albumin, stage (ISS), Hb, PLTs, bone marrow PC, M protein isotype, LDH, CRP. In particular, the rates of CR+nCR with VTD vs TD in pts with standard poor prognostic factors were as follows: ISS stage 3 (23.5% vs 6%, P=0.03), Hb&lt;10 g/dL (24% vs 4%, P=0.002), PLTs&lt;150.000/μL (35% vs 4%, P=0.009), bone marrow PC ≥50% (31% vs 13%, P&lt;0.001), IgA isotype (63% vs 15%, P&lt;0.001), LDH &gt;190 U/L (33% vs 9%, P&lt;0.001), CRP ≥8 mg/L (29% vs 10%, P=0.004). We next examined CR+nCRs by treatment arms in relationship to cytogenetics (FISH data available in 93% to 99% of all pts). Superior CR+nCR rates were effected by VTD vs TD in the presence of high-risk cytogenetics, including del(13) (39% vs 10%, P&lt;0.001), t(4;14) (39.5% vs 10%, P=0.002), combined t(4;14) and del(13) (32% vs 0%, P=0.001), and del(17p) (28.5% vs 0%, P=0.03). Remarkably, when examined in the context of the VTD arm, high-quality response rates were significantly higher for pts carrying del(13) and t(4;14) vs those who lacked these abnormalities [del(13): CR+nCR:39% vs 24%, P=0.03; ≥VGPR: 71% vs 48%, P=0.001] [t(4;14): ≥VGPR:79% vs 55%, P=0.007)]. An opposite trend was noted for pts in the TD arm, whose probability to attain ≥VGPR was adversely affected by the presence of del(13) (P=0.07) and del(17p) (P=0.03). Variables associated with achievement of CR+nCR in the two arms that retained statistical significance when assessed by multivariate Cox regression analysis included randomization to VTD (P&lt;0.001), light chain only subtype (P&lt;0.001), IgA isotype (P&lt;0.001) and Hb&gt;10 g/dL (P=0.01). In the VTD arm, a positive correlation was observed with del(13) (P=0.006) and t(4;14) (P=0.02). Response to first ASCT with melphalan 200 mg/m2 could be evaluated in 297 pts, of whom 145 randomized to VTD and 152 to TD. Randomization to VTD was closely associated with increased CR+nCR rates (54% vs 29% with TD, P&lt;0.001) and remained statistically significant (P&lt;0.001) also in the multivariate analysis. Additional factors predicting for superior post-ASCT CR+nCR rates in the multivariate setting included light chain only subtype (P&lt;0.001) and IgA isotype (P=0.005). We conclude that randomization to up-front VTD was the strongest and independent factor associated with increased rates of CR+nCR before ASCT. Superiority of VTD to TD pertained in both low-risk and high-risk sub-groups, including the traditionally unfavorable sub-groups carrying del(13), t(4,14) and del(17p). Remarkably, in the VTD arm improved postinduction CR+nCR rates were significantly associated with the presence of del(13) and t(4;14) in the multivariate analysis. Benefit from VTD vs TD as primary induction therapy translated into significantly improved CR+nCR rates after the first ASCT and remained statistically significant when assessed by multivariate analysis.

The prognosis of multiple myeloma (MM) has improved with the introduction of novel agents. These data are largely derived from clinical trials and might not reflect real-world patient outcomes accurately. We surveyed real-world data from 284 patients newly diagnosed with MM between 2010 and 2018 in Miyazaki Prefecture. The median follow-up period was 32.8 months. The median age at diagnosis was 71 years, with 68% of patients aged >65 years. The International Staging System (ISS) stage at diagnosis was I in 18.4% of patients, II in 34.1%, and III in 47.5%. Bortezomib-containing regimens were preferred as initial treatment; they were used in 147 patients (51.8%). In total, 80% of patients were treated with one or more novel agents (thalidomide, lenalidomide, or bortezomib). Among 228 patients who were treated with novel agents as an initial treatment, the overall response rate (partial response (PR) or better) to initial treatment was 78.4%, and the median time to next treatment (TTNT) was 11.6 months. In the multivariate analysis, PR or better responses to initial treatment were independently favorable prognostic factors for TTNT. The median survival time after initial therapy for patients with novel agents was 56.4 months and 3-year overall survival (OS) was 70.4%. In multivariate analysis, ISS stage I/II disease and PR or better response to initial treatment, and autologous stem cell transplantation (ASCT) were identified as independent prognostic factors for overall survival (OS).

We aimed at comparing the Durie–Salmon Plus (DS Plus) staging system based on Italian Myeloma criteria for PET USe (IMPeTUs) with other two staging systems in predicting prognosis of patients with all stages of newly diagnosed multiple myeloma (MM). A total of 33 MM patients were enrolled in this retrospective study. The variation between the DS Plus classification and Durie–Salmon staging system (DSS) or Revised International Staging System (RISS) classification was assessed. When staged by the DSS, patients in stage I and stage II did not reach the median overall survival (OS), and the median OS was 33 months for stage III (p=0.3621). When staged by the DS Plus, patients in stage I did not reach the median OS of stage I, and the median OS for stages II and III was 38 and nine months, respectively (p=0.0064). When staged by the RISS, patients in stage I did not reach the median OS, and the median OS was 33 and 16 months for stage II and stage III, respectively (p=0.0319). The concordances between two staging systems were 0.07 (DS Plus versus DSS) and 0.37 (DS Plus versus RISS), respectively. Multivariate analysis revealed that DS Plus stage III (HR: 11.539,p=0.021) and the Deauville score of bone marrow ≥4 (HR: 3.487,p=0.031) were independent prognostic factors associated with OS. Both the DS Plus based on IMPeTUs and RISS possessed a better potential in characterizing and stratifying MM patients compared with the DSS. Moreover, DS Plus stage III and the Deauville score of bone marrow ≥4 were reliable prognostic factors in newly diagnosed MM patients.

8010 Background: Analysis of minimal residual disease (MRD) in the bone marrow (BM) of patients with multiple myeloma (MM) is accepted by the IMWG to evaluate treatment efficacy and is a well-established prognostic factor. However, there is an unmet need to explore the clinical value of MRD in peripheral blood (PB). Methods: Newly diagnosed MM patients enrolled in the GEM2012MENOS65 trial received six induction (Ind) cycles of bortezomib, lenalidomide, and dexamethasone (VRD) followed by autologous stem cell transplantation (ASCT) and 2 further cycles of consolidation (Cons) with VRD. MRD was analyzed in BM using Next Generation Flow (NGF) and in serum by Mass Spectrometry (MS) using IgG/A/M, κ, λ, free κ and free λ specific beads, both after Ind, at day 100 after ASCT, and after Cons. Sequential samples from the first 184 patients were analyzed. Results: Results of both methods were in agreement (NGF+/MS+ and NGF-/MS-) in 83% of cases post-Ind (152/184), 80% post-ASCT (139/174) and 76% post-Cons (128/169). Stratifying by the log range of MRD by NGF, discordances (NGF+/MS- and NGF-/MS+) seemed to increase at the lower MRD ranges, being 22%, 21% and 19% from ≥10−5 to <10−4 and 21%, 21%, 23% at ≥x10−6(post-Ind, ASCT and Cons, respectively). Analysis of discordances showed that they could be partly explained by the higher percentages of cases found to be positive by MS as compared by NGF at part of the time-points analyzed and at each log range of MRD. From ≥10−5 to <10−4, MRD was detected by NGF in 36%, 28%, 20% of cases post-Ind, ASCT and Cons, respectively vs MS in 37%, 29%, 21% of them; at ≥x10−6, NGF was positive in 11%, 14%, 19% of cases vs MS in 23%, 19% and 16% of them. Considering NGF as a reference, the negative predictive value (NPV) of MS per MRD range (≥10−5 to <10−4 and ≥x10−6, respectively) was: post-Ind: 83% (p<0,0001), 94% (p=0,034); post-ASCT 86% (p<0,0001), 90% (p=0,022); post-Cons 89% (p<0,0001), 85% (p=0,0469). Despite these discordances, the prognostic value of each technique in terms of undetectable MRD and progression-free survival (PFS) was consistent at all time-points (Table) and further, discordant cases (NGF+/MS- and NGF-/MS+) did not display a significantly different PFS as compared to NGF-/MS- cases. Conclusions: The results of MRD assessed by NGF in BM and by MS in PB show a significant concordance and are associated with a similar prognostic value analyzed in terms of PFS. Given its high NPV, MRD in peripheral blood by MS provides a gateway for BM aspiration/biopsy and MRD assessment by NGF.[Table: see text]

Background and aims. Multiple myeloma is a frequent hematologic malignancy, in which the International Stratification Score (ISS) is widely used to estimate the overall survival. However, there are no studies in Latin America evaluating its performance. This study aims to describe the ISS performance in the overall survival estimation for newly diagnosed multiple myeloma patients in Uruguay. Methods. This is a retrospective registry‐based survival analysis through the Grupo Uruguayo de Mieloma Múltiple (GUMMA) database, including newly diagnosed multiple myeloma patients from January 2001 until May 2019. Results. 249 patients were included, 51.81% males and an average age of 63.49 years. According to ISS and Durie-Salmon score (DSS), 47.79% and 82.3% were ISS III and DSS III, respectively. Also, 32.3% were DSS B. Auto hematopoietic stem cell transplantation was performed in 31.73% of patients, and bortezomib was used in 44.18% as frontline therapy. The overall survival was 80% for ISS1, 64.9% ISS2, and 48.6% ISS3 (Log-Rank; p <0.01). The average overall survival was 116.5 months for ISS 1, 77.6 months for ISS 2, and 57.8 months for ISS 3. The hazard ratio between ISS II and ISS I was 2.42 (95% CI 1.10-5.33; p<0.05), and 3.94 (95% CI 1.88-8.26; p<0.05) between ISS III and ISS II. Conclusion. The ISS staging system allows an adequate stratification of patients according to overall survival in the real-practice setting. However, considering the relevance of the new cytogenetic advances, it is necessary to increase the availability and quality of iFISH in Latin America.

Abstract Background: The international staging system is a simple, but powerful staging system that is based on two simple and easily available laboratory measurements. The system was developed and validated on a large group pf patients from across the world and has become the standard for patients with newly diagnosed myeloma. While it’s prognostic value is clear in patients with newly diagnosed myeloma, its value at relapse has not been explored. Methods: We examined a uniform cohort of patients relapsing after an autologous stem cell transplant to assess the utility of ISS determined at the time of documented relapse. Relapse was defined using standard EBMTR response criteria. Beta-2 microglobulin and albumin values from within 30 days of the date of relapse were extracted from the medical records. ISS was determined based on the published cut offs. Results: Of the 389 patients evaluated, 132 had values available for B2M and 276 patients had the serum albumin available. Only 131 patients had both the data available and the ISS stage could be determined. Of these patients, 64 patients (49%) were ISS stage I, 50 (38%) were stage II and 17 (13%) were stage III. An albumin &lt; 3.5 mg/dL was prognostic for overall survival post relapse with a median survival of 10.5 months for those with albumin &lt; 3.5 mg/dL compared to 26.3 months for the rest of the group (P &lt; 0.0001). Similarly the median OS from relapse was 15 months for those with B2M &gt; 3.5 mg/dL compared to 23.3 months for those with lower B2M (P = 0.014). The ISS stage predicted overall survival for this group of patients with the OS from relapse estimated at 27.3 mos, 17.8 mos and 12.3 months for ISS stage I, II and III respectively. Conclusions: In a uniform group of patients relapsing after autologous stem cell transplantation, the B2M and albumin maintain their prognostic value and allows the use of the International Staging System for determining prognosis. This supports the use of ISS stage in relapsed trials and will allow comparisons across studies. Results should be validated in a larger dataset that will allow comparisons to other known prognostic factors. Figure Figure

Abstract Solitary plasmacytoma (PCM) is a focal, neoplastic, plasma cell disorder without evidence of systemic disease. While PCM is a clinically distinct entity, survival can be limited by progression to multiple myeloma. Prior studies have attempted to identify factors influencing survival in PCM but have been limited by small patient cohorts. This study identified 1472 patients with PCM using the SEER database between 1988 and 2004. The median age of the patients was 64 years (range 12–97), 65.4% male, 34.6% female, 83% Caucasians, 10.7% African Americans and 6.3% other races. 63.8% had medullary PCM and 36.2% extramedullary PCM. 84% of medullary PCM occurred in axial skeleton and the rest in appendicular skeleton. Extramedullary PCM most frequently occurred in the head and neck region (51.4%) followed by skin/subcutaneous tissue (16.2%), GI tract 6% and other sites (26.4%). 55.2% were treated with radiation therapy alone, 29.5% with radiation therapy and surgery and 15.3% with surgery alone. 558 died during this period and the mean overall survival was 6.83 years (range, 0–16.9). The cause of death was multiple myeloma in 49.6%, other cancers 20.9% and cardiovascular diseases 12.9%. In all patients, survival probability at one year was 87.6% (95% CI, 85–89%), at five years was 58.9% (95% CI, 56–62%), and at 10 years was 40.0% (95% CI, 36–44%). The five year overall survival in the ≤40yo cohort was 83.5% as compared to 76.7% and 44.8% in the 40–60yo and &gt;60yo groups, respectively (p&lt;0.0001). The five year disease specific survival probability in the ≤40yo cohort was 94.5% as compared to 86.0% and 66.2% in the 40–60yo group and &gt;60yo group, respectively (p&lt;0.0001) (figure 1)). Overall survival in the extramedullary PCM was 65.9% at five years as compared to 54.6% in the medullary PCM (p&lt;0.0001) and the disease specific survival in the extramedullary PCM was 86.2% compared to 70.1% in the medullary PCM (p&lt;0.0001) (figure 1). Multivariate analysis of disease specific survival revealed that younger age, male gender, extramedullary type, and race other than African American or Caucasian were favorable prognostic factors (Table 1). Younger age, extramedullary site, treatment with XRT + surgery, and race other than African Americans were associated with improved overall survival by multivariate analysis (Table 1). To our knowledge, this is the largest published review of survival in PCM. This study identifies several prognostic risk factors influencing survival in PCM. These risk factors can be used to identify patients at high risk for progression to multiple myeloma. Those at highest risk could be considered for future trials comparing adjuvant systemic therapy compared to local therapy alone. Table 1.

Abstract Abstract 1675 Background: Acute myeloid leukemia (AML) is characterized by rapid growth, resistance to therapy, and poor overall survival. Clinical and biologic prognostic markers can help define pathogenesis, guide treatment, and identify novel therapies. Phosphorylated signal transducer and activator of transcription 5 (pSTAT5) is one such potential marker. The transcription factor STAT5 regulates many aspects of cell growth, survival, and differentiation. Constitutive activation of STAT5 (by phosphorylation) has been identified in a number of malignancies, including AML. We investigated whether the level of pSTAT5 expression correlates with complete remission (CR) rates, progression-free survival (PFS), and overall survival (OS) in patients (pts) with newly diagnosed AML. Methods: From 1999 to 2005, all adult pts with newly diagnosed AML (WHO criteria) receiving induction chemotherapy and with an available diagnostic bone marrow biopsy performed at our institution were evaluated. B5-fixed bone marrow core biopsies were reviewed for areas with the highest concentration of blasts. A tissue microarray was constructed using 1 mm cores. The cores were arrayed in duplicate in the majority of samples. Immunohistochemistry was performed for pSTAT5 with anti-pSTAT5 a/b Y695/99 mouse monoclonal antibody (AX1; Advantex Bioreagents) using automated stainers and heat-induced epitope retrieval. In each case, five hundred blasts were counted. The percentage of cells staining positive for pSTAT5 expression was determined by a pathologist blinded to clinical results. Standard metaphase karyotypes were classified into cytogenetic (CG) risk groups by CALGB criteria. Cox proportional hazards analysis was used to identify univariate and multivariate prognostic factors for CR, PFS, and OS, including age at diagnosis, history of an antecedent hematologic disorder (AHD), WBC at diagnosis, pSTAT5 expression, and CG risk group. Results: Adequate tissue and clinical data were available in 112 pts. The median age was 57 years, and median WBC at diagnosis 12.0 K/ μL. Twenty six percent of pts had favorable CG, 41% intermediate risk, 27% high risk, and 6% other (unknown or could not be classified). Nineteen percent of pts had an AHD. pSTAT5 expression was absent in 58% of pts. The remainder of the pts had: 1–5% pSTAT5 (25% of pts), 10% pSTAT5 (11% of pts), 20% pSTAT5 (4% of pts), 30% pSTAT5 (1% of pts), and 50% pSTAT5 (2% of pts). Seventy percent of all pts achieved a CR following induction chemotherapy. Sixty-four percent of pts received post-remission chemotherapy, 3.6% an autologous transplant, and 13.6% an allogeneic transplant in first CR. Median PFS and OS were 9.6 months and 16.0 months, respectively. On univariate analysis, age, history of AHD, WBC at diagnosis, CG risk, and any pSTAT5 expression were prognostic factors for PFS and OS. In multivariable analyses controlling for the above prognostic factors, pSTAT5 expression > 0 was also significantly associated with an increased risk of death (HR 1.96, 95% CI 1.19–3.23, p=0.008), progression or death (HR 1.64, 95% CI 1.01–2.66, p=0.046), and relapse after achieving CR (HR 2.31, 95% CI 1.16–4.63, p=0.018). pSTAT5 expression was not a predictor of achievement of CR. Conclusions: pSTAT5 expression in newly diagnosed adults with AML is associated with a decreased PFS, decreased OS, and increased risk of relapse. Validation of its prognostic value requires additional study. Agents targeting this signaling pathway might improve the outcome of pts with AML.
