Abstract Introduction: To evaluate a new enhanced IPI proposed by the National Comprehensive Cancer Network (NCCN-IPI) in DLBCL patients, we compared the international prognostic index (IPI), R-IPI and NCCN-IPI in DLBCL patients treated with rituximab, cyclophosphamide, hidroxydaunorubicin, vincristine and prednisone (R-CHOP). Methods: From June 2008 to November 2011 we retrospectively evaluated 146 DLBCL patients treated with R-CHOP-21 referred for cancer treatment in a single university institution in Brazil. Patient's clinical data were assessed to calculate the IPI, R-IPI and NCCN-IPI. Results: Patient's median age was 58.9 years (range 16 – 86); 85 (57.8%) were female. According to IPI, risk categories were low (n=41, 28.1%), low-intermediate (n=43, 29.5%), high-intermediate (n=37, 25.3%) and high (n=25, 17.1%). Using R-IPI, risk categories were very good (n=19, 13%), good (n=65, 44.5%) and poor (n=62, 42.5%). According to NCCN-IPI, risk categories were low (n=12, 8.2%), low-intermediate (n=52, 35.6%), high-intermediate (n=62, 42.5%) and high (n=20, 13.7%). At 30 months (median follow up 17.7 months - range 0.6-58.2 months) the overall survival (OS) was 75.5%. The progression-free survival (PFS) at a median follow-up of 16.3 months (range 0.6-52.4) was 68.3% for all patients. Using IPI, the OS at 30 months did not differ between low and low-intermediate risk patients (96.8% vs. 82.2%; p=0.136); however, it was higher than the OS of high-intermediate risk (n=37; 96.8% vs 74.1% p=0.11) and high-risk (n=25; 96.8% vs 41% p < 0.001) patients (Figure 1). The NCCN-IPI demonstrated significant differences in OS (p < 0,001) and PFS (p<0.001) among low-intermediate, high-intermediate, and high risk groups, with the high-risk group exhibiting worse OS (32.1% in 30 months) (Figure 2). According to IPI, the OS in high-risk patients was 41%. Figure 1: OS and PFS according to International Prognostic Index (IPI) Figure 1:. OS and PFS according to International Prognostic Index (IPI) Figure 2: OS and PFS according to NCCN-IPI Figure 2:. OS and PFS according to NCCN-IPI Figure 3 Figure 3. Conclusion: In our study the NCCN-IPI, but not the IPI or R-IPI was able to discriminate a high-risk group of DLBCL patients treated with R-CHOP with worse OS.

Risk Stratification System

The baseline International Prognostic Index (IPI) is not sufficient for the initial risk stratification of patients with diffuse large B-cell lymphoma (DLBCL) treated with R‐CHOP (rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone). The aims of this study were to evaluate the prognostic relevance of early risk stratification in DLBCL and develop a new stratification system that combines an interim evaluation and IPI. This multicenter retrospective study enrolled 314 newly diagnosed DLBCL patients with baseline and interim evaluations. All patients were treated with R-CHOP or R-CHOP-like regimens as the first-line therapy. Survival differences were evaluated for different risk stratification systems including the IPI, interim evaluation, and the combined system. When stratified by IPI, the high-intermediate and high-risk groups presented overlapping survival curves with no significant differences, and the high-risk group still had &gt;50% of 3-year overall survival (OS). The interim evaluation can also stratify patients into three groups, as 3-year OS and progression-free survival (PFS) rates in patients with stable disease (SD) and progressive disease (PD) were not significantly different. The SD and PD patients had significantly lower 3-year OS and PFS rates than complete remission and partial response patients, but the percentage of these patients was only ~10%. The IPI and interim evaluation combined risk stratification system separated the patients into low-, intermediate-, high-, and very high-risk groups. The 3-year OS rates were 96.4%, 86.7%, 46.4%, and 40%, while the 3-year PFS rates were 87.1%, 71.5%, 42.5%, and 7.2%. The OS comparison between the high-risk group and very high-risk group was marginally significant, and OS and PFS comparisons between any other two groups were significantly different. This combined risk stratification system could be a useful tool for the prognostic prediction of DLBCL patients.

Abstract Background and Aims IgA nephropathy (IgAN) is one of the most prevalent glomerulopathies worldwide with broad variable clinical presentation and extremely heterogeneous risk of progressive CKD and ESKD. It was recommended risk stratifying patients in order to target immunosuppressive treatment to high-risk patients. The OXFORD MEST classification and, more recently, a new international risk-prediction tool for IgAN (IgANPT) help to predict kidney outcomes and stratify patient risk, eventually aiding in treatment decision. Here, we analyzed a single center cohort of IgAN to investigate if treatment decisions were accurately accomplished using individualized risk from the IgANPT. Method A retrospective analysis of all kidney biopsies performed from January 2010 to December 2019 in a Nephrology Department was performed and adult patients with IgAN diagnosis were selected. The presence of IgA vasculitis and Henoch-Schönlein purpura as well as lack of follow-up data were exclusion criteria. Clinical, laboratorial and pathological data were collected, including treatment and kidney outcome. Risk of kidney progression decline was assessed by using the on-line web-based calculator of the IgANPT. Results A total of 33 patients met the study criteria, with median age at diagnosis of 58 (IQR 38 - 68) years-old, mostly male (84,8%, N=28) and all Caucasian. At biopsy time 60,6% (N=20) had hypertension, only 15,5% (N=5) diabetes mellitus and 57,6% (N=19) were under ACE inhibitors/ARBs. Median GFR at biopsy time was 57 (IQR 20 - 78,5) ml/min/1.73m2. More than half of the patients (57,6%, N=19) had GFR &lt;60ml/min/1.73m2. All patients had proteinuria (UACR &gt; 300mg/g), with 18,2% (N=6) in the nephrotic range. Hematuria was present in almost all patients. Overall MEST classification was: 51,5% (N= 17) with M1 score, 39,4% (N=13) E1, 66,7% (N=22) S1 and 45,5% (N=15) had T ≥1 score (2 patients with T2). Crescents were present in 27,3% of the biopsies (N=9). Near one-half of the patients (45,5%, N=15) presented IgA deposits on both mesangium and capillary wall. Around one-third of patients (30,3%, N=10) progressed to ESKD during follow up. According to the risk of kidney disease progression in 60-months calculated with IgANPT, patients were stratified into low/intermediate risk in 21,2% (N=7) of cases (mean predicted risk &lt; 4,7%) and high risk in 78,8% (N=26) of cases (mean predicted risk &gt; 4,7%). Using the chi-squared test the high-risk group was associated with progression to ESKD(p=0,019). On the contrary none of the low-risk group progressed to ESKD. The majority of patients received supportive treatment (87,9%, N= 29), mainly with ACEi/ARB (N=31) and omega (15,2%, N=5). Immunosuppressive treatment included mainly corticosteroids (51,5%, N=17), with other options being (12,1% N=4): cyclophosphamide (N=2), ciclosporin (N=1) and MMF (N=1). From the group of low/intermediate risk patients, only two (28,5%) received immunosuppressive treatment with either oral or intravenous corticosteroids. On the other hand, from the high-risk group, more than one third of patients (38,4%, N=10) did not receive immunosuppressive treatment. Conclusion A better prediction of kidney outcomes and consequent better patient selection for IS therapy may be challenging in IgA nephropathy. In spite of the existent tools, it is still difficult to determine which patients benefit from immunosuppressive treatment. In this case series we stratified our patients by using the IgANPT identifying who was at higher risk of progression to ESKD, in whom, a more aggressive treatment could have potentially benefit avoiding kidney disease progression. It was also important to stratify patients at low-risk, in whom immunosuppressive treatment could carry risk of adverse events with no additional advantage in kidney outcomes.

Cns Relapse

Purpose To develop and validate a risk score for relapse in the CNS in patients with diffuse large B-cell lymphoma (DLBCL). Patients and Methods A total of 2,164 patients (18 to 80 years old) with aggressive B-cell lymphomas (80% DLBCL) treated with rituximab and CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone)-like chemotherapy, who were enrolled in studies from the German High-Grade Non-Hodgkin Lymphoma Study Group and the MabThera International Trial, were analyzed for occurrence of relapse/progression in the CNS. The resulting risk model was validated in an independent data set of 1,597 patients with DLBCL identified in the British Columbia Cancer Agency Lymphoid Cancer database. Results The risk model consists of the International Prognostic Index (IPI) factors in addition to involvement of kidneys and/or adrenal glands (CNS-IPI). In a three-risk group model, the low-risk group (46% of all patients analyzed), the intermediate-risk group (41%), and the high-risk group (12%) showed 2-year rates of CNS disease of 0.6% (CI, 0% to 1.2%), 3.4% (CI, 2.2% to 4.4%), and 10.2% (CI, 6.3% to 14.1%), respectively. Patients from the validation British Columbia Cancer Agency data set showed similar rates of CNS disease for low-risk (0.8%; CI, 0.0% to 1.6%), intermediate-risk (3.9%; CI, 2.3% to 5.5%), and high-risk (12.0%; CI, 7.9% to 16.1%) groups. Conclusion The CNS-IPI is a robust, highly reproducible tool that can be used to estimate the risk of CNS relapse/progression in patients with DLBCL treated with R-CHOP (rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone) chemotherapy. Close to 90% of patients with DLBCL belong to the low- and intermediate-risk groups and have a CNS relapse risk < 5%; they may be spared any diagnostic and therapeutic intervention. In contrast, those in the high-risk group have a > 10% risk of CNS relapse and should be considered for CNS-directed investigations and prophylactic interventions.

Abstract Acute promyelocytic leukemia (APL) has become one of the more readily treatable subtypes of acute myeloid leukemia on the basis of its particular sensitivity to anthracyclines and the introduction of the differentiating agent all-trans retinoic acid (ATRA). Unfortunately some patients will ultimately relapse after achievement of complete remission. A PETHEMA and GIMEMA (PETH/GIM) cooperative group joint study sought to identify risk factors associated with relapse and developed a predictive model based on white cell count (WCC) and platelet count (Plt) at diagnosis. This model for relapse free survival was capable of segregating patients into low risk (WCC &lt; 10 x 109/L / Plt &gt; 40 x 109/L), intermediate risk (WCC &lt; 10 x 109/L / Plt &lt; 40 x 109/L), and high risk (WCC &gt; 10 x 109/L). A subsequent follow up study demonstrated improved outcomes for intermediate and high risk group patients treated with an anthracycline and ATRA based risk adapted strategy. We reviewed 60 cases of adult de novo APL treated at Vancouver General Hospital from August 1995 to December 2003. Thirty five females (58%) and 25 males (42%) were treated with a standard induction and consolidation protocol consisting of 3 cycles of Daunorubicin (60 mg/m2 OD for 3 days), Cytosine arabinoside (100 mg/m2 BID for 7 days), and ATRA (45 mg/m2/day until complete remission or a maximum of 60 days). In 2000 maintenance therapy was introduced and ATRA and/or varying doses of Methotrexate and 6-Mercaptopurine were then instituted for up to 2 years duration. At the completion of induction chemotherapy complete morphological and cytogenetic remission was achieved in 55/60 patients (92%) with 4 induction failures and only 1 death during induction treatment. Subsequently during and after consolidation and maintenance therapy at a median follow up of 34 months there were a total of 10 episodes of relapse (18%) in these 55 patients. When the 55 patients in complete remission were stratified at diagnosis by the PETH/GIM risk group there were 18 low risk patients (33%), 26 intermediate risk patients (47%), and 11 high risk patients (20%). The number of relapses was 6 in the low risk group (33%), 4 in the intermediate risk group (15%) and no relapses were identified in the high risk group. In our experience the predictive model for relapse free survival developed by the PETH/GIM cooperative group does not identify those at most likelihood for subsequent relapse after achieving an initial complete remission. The greatest number of relapse was seen in the low risk group with no relapses in the high risk group. These variations may be explained in part by the different chemotherapy treatment protocols with variable maintenance therapy. Future investigation will focus on the prognostic role of immunophenotype, additional cytogenetic abnormalities and molecular isoforms in determining outcome in APL.

Abstract Purpose: The International Prognostic Index (IPI) and Follicular Lymphoma Prognostic Index (FLIPI) are used as prognostic indices for NHL and indolent lymphoma. However, marginal zone B-cell Lymphoma (MZL) evidences a distinctive clinical presentation and a natural course; thus, in this study, we attempted to devise an adequate prognostic index for MZL. Patients and method: From 1990 to 2005, 205 patients diagnosed with MZL were retrospectively reviewed. After analysis of the prognostic factors, progression free survival (PFS) and overall survival (OS), we constructed a prognostic index of MZL (MZLPI) via the summation of each factor. We then compared PFS and OS with IPI, FLIPI, and MZLPI. Results: According to our multivariate analysis of PFS and OS of MZL, nodal MZL, ECOG performance ≥ 2 and advanced stage were composed of MZLPI. MZLPI was grouped as follows: score 0 as a low risk group, score 1 as an intermediate risk group, and score ≥2 as a high risk group. The PFS curve, according to MZLPI results, evidenced a more discriminated pattern than IPI and FLIPI, and this was especially true in the intermediate risk group. In OS, MZLPI (P=0.0007) evidenced a more discriminated pattern than IPI (P=NS) or FLIPI (P=0.0044). Conclusion: MZLPI, which is constructed of relatively simple factors, may represent a useful prognostic index for the prediction of PFS and OS in MZL, and may also be used as a substitute for IPI or FLIPI.

Abstract Abstract 3100 The Follicular Lymphoma International Prognostic Index (FLIPI) is the most useful prognostic index for follicular lymphoma (FL). FLIPI was developed from retrospective data, which was based on treatment without rituximab (R) therapy and did not contain β2-microglobulin data of some cases. Recently the working group that had suggested FLIPI proposed FLIPI2, based on prospectively collected data. However, FLIPI2 contains data on several different treatment methods, such as treatment with or without R therapy. The present study aimed to retrospectively analyze the prognosis of FL uniformly treated with the combination of R, cyclophosphamide, doxorubicin, vincristin, and prednisone (R-CHOP). This study involved 114 patients consecutively diagnosed with FL who were treated with R-CHOP and were registered in the data-base of the Yokohama City University Hematology Group between January 2001 and October 2009. All the parameters required for FLIPI and FLIPI2 calculation were present in 108 patients (men, 53; women, 55, median age; 57 years [34- 78 years]). The median follow-up period was 31.7 months (0.8- 97.5 months). According to the FLIPI score, 50 patients (46.3%) were in the high-risk group (HR); 31 patients (28.7%), the intermediate-risk group (IR); and 27 patients (25.0%), the low-risk group (LR). On the basis of the FLIPI2 score, 45 patients (41.7%) were in HR; 52 patients (48.1%), IR; and 11 patients (10.2%), LR. According to FLIPI, the 5-year overall survival (5yOS) was 74.1% (95% CI, 58.1– 94.4%) for HR, 89.5% (95%, CI, 76.6– 100%) for IR, and 100% for LR (p = 0.0049); the 5-year time to failure (5yTTF) was 42.3% (95% CI, 26.0– 68.9%) for HR, 39.1% (95% CI, 22.7– 67.3%) for IR, 66.4% (95% CI, 47.2– 93.4%) for LR (p = 0.244). According to the FLIPI2 score, 5yOS was 71.3% (95% CI, 53.2– 95.6%) for HR, 85.6 % (95% CI, 72.0– 100%) for IR, and 100% for LR (p = 0.197), the 5yTTF was 35.8% (95% CI, 20.0– 64.2%) for HR, 46.7% (95% CI, 31.1– 70.3%) for IR, and 76.2% (95% CI, 52.1– 100%) for LR (p = 0.075). In conclusion, in FL patients treated with R-CHOP, FLIPI provided a more accurate OS than that provided by FLIPI2; however, FLIPI2 provided a more accurate TTF than that provided by FLIPI.

Abstract Background Following Myocardial Infarction (MI), patients are at increased risk for recurrent cardiovascular events, particularly during the immediate period. Yet some patients are at higher risk than others, owing to their clinical characteristics and comorbidities, these high-risk patients are less often treated with guideline-recommended therapies. Aim To examine temporal trends in treatment and outcomes of patients with MI according to the TIMI risk score for secondary prevention (TRS2°P), a recently validated risk stratification tool. Methods A retrospective cohort study of patients with an acute MI, who underwent percutaneous coronary intervention and were discharged alive between 2004–2016. Temporal trends were examined in the early (2004–2010) and late (2011–2016) time-periods. Patients were stratified by the TRS2°P to a low (≤1), intermediate (2) or high-risk group (≥3). Clinical outcomes included 30-day MACE (death, MI, target vessel revascularization, coronary artery bypass grafting, unstable angina or stroke) and 1-year mortality. Results Among 4921 patients, 31% were low-risk, 27% intermediate-risk and 42% high-risk. Compared to low and intermediate-risk patients, high-risk patients were older, more commonly female, and had more comorbidities such as hypertension, diabetes, peripheral vascular disease, and chronic kidney disease. They presented more often with non ST elevation MI and 3-vessel disease. High-risk patients were less likely to receive drug eluting stents and potent anti-platelet drugs, among other guideline-recommended therapies. Evidently, they experienced higher 30-day MACE (8.1% vs. 3.9% and 2.1% in intermediate and low-risk, respectively, P<0.001) and 1-year mortality (10.4% vs. 3.9% and 1.1% in intermediate and low-risk, respectively, P<0.001). During time, comparing the early to the late-period, the use of potent antiplatelets and statins increased among the entire cohort (P<0.001). However, only the high-risk group demonstrated a significantly lower 30-day MACE (P=0.001). During time, there were no differences in 1-year mortality rate among all risk categories. Temporal trends in 30-day MACE by TRS2°P Conclusion Despite a better application of guideline-recommended therapies, high-risk patients after MI are still relatively undertreated. Nevertheless, they demonstrated the most notable improvement in outcomes over time.

Abstract Background: The Follicular Lymphoma International Prognostic Index (FLIPI) has been developed to predict prognosis and to allow risk adapted treatment decisions in patients with follicular lymphoma (FL) before the widely use of Rituximab. However, the addition of Rituximab to standard induction chemotherapy with its long-term beneficial effects has profoundly changed the treatment outcome in patients with advanced stage FL and has become the new standard in the first line therapy of this disease. Therefore, we addressed the question, whether the prognostic value of the FLIPI could be reconfirmed in patients with advanced stage FL treated initially with a rituximab/chemotherapy combination. Methods: The FLIPI index was tested in patients treated with Rituximab and CHOP (Cyclophosphamide, Doxorubicin, Vincristine and Prednisone, R-CHOP) in a prospective multicenter phase 3 trial of the GLSG using the time to treatment failure (TTF) as target parameter. Results: 362 Patients treated with R-CHOP were evaluable for TTF. Of the 338 patients evaluable for all FLIPI risk factors, 14% of patients were classified as low, 41% as intermediate and 45% as high risk. After a median follow-up time of 20 months, patients with low risk and intermediate risk FLIPI had almost identical TTF (2-years TTF 92% vs 90%, 95% C.I., 83% to 100% and 84% to 96%, respectively). In contrast, the TTF was significantly shorter in the high risk FLIPI group (2-years TTF 67%, 95% C.I., 58% to 76%) as compared to the combined low/intermediate risk FLIPI group (relative risk 3.0, 95% C.I., 1.7 to 5.1; p &lt; 0.0001). In addition, responding patients with high risk FLIPI had a significantly shorter progression free survival as compared to the low/intermediate risk group (relative risk 3.3, 95% C.I., 1.8 to 6.0; p &lt; 0.0001). When postremission treatment was taken into account, the FLIPI separated the high risk group from the low/intermediate risk group in 65 patients treated with autologous stem cell transplantation (relative risk 6.0, 95% C.I., 1.4 to 25.2) as well as in 242 patients who had received IFN-α maintenance or no postremission therapy (relative risk 3.2, 95% C.I., 1.8 to 5.8). As the FLIPI was able to separate the high from the low/intermediate risk group in patients with advanced follicular lymphoma treated initially with Rituximab and CHOP we next performed a multivariate analysis to determine the impact of the individual parameters incorporated in the FLIPI on the TTF. The serum LDH level greater than the upper normal limit (relative risk 2.6, 95% C.I., 1.5 to 4.5) and the hemoglobin level below 12 g/dl (relative risk 2.5, 95% C.I., 1.4 to 4.3) were independently associated with a shorter TTF in these patients, whereas the age and the number of nodal areas were not discriminant. Conclusion: Taken together, these data indicate that the FLIPI is a valid prognostic index for identifying high-risk patients in FL, also after front-line combined immuno-chemotherapy. The index will remain an important tool to adjust treatment decisions in individual patients according their risk profile and to design clinical trials for the different risk groups in the era of antibody-based therapy.

Abstract Abstract 858 Prior studies have shown that combination chemotherapy using high doses of antimetabolites and alkylating agents over a short duration is effective treatment for Burkitt leukemia and lymphoma. Adults able to tolerate this therapy have had > 50% long term survival, although those with higher risk by the International Prognostic Index (IPI) have had inferior outcomes. Between 5/2002 and 9/2009, we enrolled 105 adults (19-79 yrs old) with untreated Burkitt leukemia/lymphoma onto a phase II study of a high intensity chemo-immunotherapy regimen to assess the benefit of adding rituximab plus growth factor support to the intensive chemotherapy regimen developed in CALGB 9251 and evaluated patterns of relapse when prophylactic cranial irradiation was not given. All subjects were HIV negative and had serum creatinine and bilirubin ≤1.5 × upper limit. Complete data are available on 105 patients for toxicity and 103 patients for efficacy. Methods: Treatment began with cyclophosphamide (CY) 200 mg/m2 × 5 days and prednisone 60 mg/m2 × 7 days. Cycle 2 was started on Day 8 after entry. Cycles 2, 4, and 6 consisted of ifosfamide 800 mg/m2 on days 1–5, methotrexate (MTX) 1.5 g/m2 infused over day 1 with leucovorin rescue, vincristine (VCR) 2 mg day 1, Ara-C 1 gm/m2 days 4 and 5, VP-16 80 mg/m2 days 4 and 5, and dexamethasone 10 mg/m2 on days 1–5. Cycles 3, 5, and 7 included the same doses of MTX, VCR, and dexamethasone, with CY 200 mg/m2 IV on days 1–5 and doxorubicin 25 mg/m2 days 4 and 5. Cycles were delivered every 21 days if blood counts had recovered. Filgrastim was given at 5μg/kg/day SC beginning day 7 of each cycle and continuing until the absolute neutrophil count recovered to > 5000/μL. Rituximab was initiated during cycle 2 on day 8 at 50 mg/m2 and on days 10 and 12 at 375 mg/m2. During cycles 3 through 7, rituximab was infused only on day 8 of each course at 375 mg/m2. Central nervous system (CNS) prophylaxis consisted of triple intrathecal therapy on day 1 of cycles 2–7 (6 total doses). Results: 27% of patients were ≥60 years old; 70% were male; 46% had intermediate or high risk disease by the IPI (Table). Overall, 75 of 105 subjects completed all 7 planned courses of therapy. 82% attained a complete response (CR), and 87% of these remain in CR at last follow up. 7% had a partial response. With median follow up of survivors of 3.2 years, 2 year event free survival (EFS) and overall survival (OS) were 77% and 79%, respectively, with a trend favoring those <60 years old (87% and 87%, respectively). There were clear differences in outcome based on IPI score with 2 year EFS and OS for low risk patients of 90% and 92% versus 55% and 55% for high risk patients, respectively (Figure). This protocol did not use prophylactic CNS radiation, and 4 pts had documented CNS relapses; 2 had intermediate and 1 high IPI disease; the 4th was unknown. Relapse after 2 years was rare. 7 subjects (6.8%) died from treatment related causes (1 CNS bleed, 4 infections, 2 respiratory failure). Nearly all subjects experienced the anticipated severe hematologic toxicities. The most common grade 3 and 4 non-hematologic toxicities included stomatitis/upper GI toxicity (∼ 66%), nausea/vomiting (20%), fatigue (26%), rash or erythema multiforme (10%), diarrhea (10%), pulmonary or CNS bleeding (11%), clinically documented infections (72%), neurologic disturbances (8%), and dyspnea (10%). 8 pts (8%) had tumor lysis syndrome (all grade 3). Conclusion: This regimen provides a high rate of durable remissions in adult patients with a manageable side effect profile. Chemoimmunotherapy should be the standard for adult patients with Burkitt leukemia/lymphoma. Disclosures: Off Label Use: Rituximab for use in Burkitt's. Cheson:Genentech: Consultancy.

Abstract Background Patients with multiple myeloma (MM) have a 9-fold increased risk of developing venous thromboembolism (VTE). Current guidelines recommend pharmacologic thromboprophylaxis in patients with MM receiving an immunomodulatory agent in the presence of additional VTE risk factors (NCCN 2015, ASCO 2014, ACCP 2012). However, putative risk factors vary across guidelines and no validated VTE risk tool exists for MM. Khorana et al. developed a VTE risk score in patients with solid organ malignancies and lymphoma (Blood, 2008). We sought to apply the Khorana et al. score in a population with MM. Methods We identified patients diagnosed with MM within the Veterans Health Administration (VHA) between September 1, 1999 and December 31, 2009 using the International Classification of Diseases (ICD)-03 code 9732/3. We followed the cohort through October 2014. To eliminate patients with monoclonal gammopathy of undetermined significance and smoldering myeloma, we excluded patients who did not receive MM-directed therapy within 6 months of diagnosis. We also excluded patients who did not have data for hemoglobin (HGB), platelet (PLT) count, white blood count (WBC), height and weight, as these are all variables included in the Khorana et al. risk model. Height and weight were assessed within one month of diagnosis and used to calculate body mass index (BMI). We measured HGB, PLT count, and WBC count prior to treatment initiation: within two months of MM diagnosis. A previously validated algorithm, using a combination of ICD-9 code for VTE plus pharmacologic treatment for VTE or IVC filter placement, identified patients with incident VTE after MM diagnosis (Thromb Res, 2015). The study was approved by the Saint Louis VHA Medical Center and Washington University School of Medicine institutional review boards. We calculated VTE risk using the Khorana et al. score: We assigned 1 point each for: PLT ≥ 350,000/μl, HGB < 10 g/dl, WBC > 11,000/μl, and BMI ≥ 35 kg/m2. Patients with 0 points were at low-risk, 1-2 points were considered intermediate-risk and ≥3 points were termed high-risk for VTE. We assessed the relationship between risk-group and development of VTE using logistic regression at 3- and 6-months. We tested model discrimination using the area under the receiver operating characteristic curve (concordance statistic, c) with a c-statistic range of 0.5 (no discriminative ability) to 1.0 (perfect discriminative ability). Results We identified 1,520 patients with MM: 16 were high-risk, 802 intermediate-risk, and 702 low-risk for VTE using the scoring system in the Khorana et al. score. At 3-months of follow-up, a total of 76 patients developed VTE: 27 in the low-risk group, 48 in the intermediate-risk group, and 1 in the high-risk group. At 6-months of follow-up there were 103 incident VTEs: 41 in the low-risk group, 61 in the intermediate-risk group, and 1 in the high-risk group. There was no significant difference between risk of VTE in the high- or intermediate-risk groups versus the low-risk group (Table 1). The c-statistic was 0.56 at 3-months and 0.53 at 6-months (Figure 1). Conclusion Previously, the Khorana score was developed and validated to predict VTE in patients with solid tumors. It was not a strong predictor of VTE risk in MM. There is a need for development of a risk prediction model in patients with MM. Figure 1. Figure 1.
