Younger Age at Diagnosis Is Associated with an Increased Risk of Venous Thromboembolism in Multiple Myeloma

Abstract Introduction Multiple Myeloma (MM) patients are at an approximately 9-fold increased risk of developing venous thromboembolism (VTE), with risk being highest in the first year following diagnosis1. VTE is associated with significant morbidity and negatively influences survival in MM2. Although the Khorana score has been shown to predict rate of thrombosis in solid tumors, the validity of this score in haematological malignancies has yet to be assessed. Given the elevated rates of VTE in these conditions, in particular MM, clinically relevant risk prediction scores are essential. Additionally, data from the MRC-XI trial indicates that standard thromboprophylaxis may not prevent VTEs in MM3. Therefore identification of risk factors for MM-VTE are required to improve our understanding of the pathophysiology of thrombosis and to develop risk-adapted clinical practice guidelines. Through interrogation of an extensive clinical database we sought to identify factors predictive for VTE in our MM population. Methods We performed a retrospective cohort study of all newly diagnosed MM patients at our centre from 2001-2017. Patient medical records were reviewed for clinical and laboratory data including FBC parameters, beta-2-microglobulin, paraprotein and serum free light chain on the day of diagnosis, to minimize steroid effect. All VTE events were recorded, along with MM treatment regimen and thromboprophylaxis at time of event. History of thrombosis was defined as occurring within 6 month prior to, or following a diagnosis of MM. Patients with MGUS or smoldering MM were excluded. Statistical analysis including logistic regression and cox proportional hazard modelling was performed using SPSS (IBM Analytics, USA). A comparison of mortality was also performed between age matched cases with VTE and controls without VTE. Results Over a period of 17 years, 266 patients were diagnosed with myeloma, of which 34 (12.7%) developed VTE following MM diagnosis or within the preceding six months. The mean age of the VTE cohort at MM diagnosis was younger than the mean age of the non-VTE cohort (62.5 years vs. 68.6 years). Pulmonary embolisms and deep vein thromboses were equally represented (44% and 56% respectively) and additional risk factors for thrombosis were present in 46% of patients, not related to MM therapy. Of the patients on immunomodulatory drugs or corticosteroids at time of VTE, all were receiving thromboprophylaxis with either low molecular weight heparin (LMWH) or aspirin at time of VTE. The mortality odds ratio was 3.3 (95% CI 2.4-4.5) in patients who developed VTE in comparison to age matched controls with MM. Younger age at MM diagnosis (<64 years) predicted for VTE occurrence in logistic regression univariate (p-value=0.002) and multivariate analysis (p=0.004). Higher white cell count (WCC) at MM diagnosis showed a trend toward significance in univariate analysis (p-value=0.06) and, in combination with age, demonstrated an area under the curve of 0.72 on ROC analysis for prediction of VTE. Interestingly, the increased risk of VTE in younger patients was not related to longer duration of MM exposure or longer follow up as there was no statistically significant difference in time to VTE between all age groups (median 9 months). Other parameters incorporated in the Khorana score, such as haemoglobin and platelet count did not increase the risk of VTE (p-value=0.57, and 0.25 respectively). Conclusions Our data confirms that VTE is associated with an increased mortality in MM patients and estimates the risk of death to be 3.3 fold higher in these patients. As recently reported in a large cohort of MM patients, younger age is associated with an increased risk of VTE development4, our data support this finding and excludes longer duration of MM, and follow-up time, as confounding variables. Importantly, our data confirms, in unselected "real world" patients the signal that is now apparent from analysis of VTE in the MRC-XI trial3, that thromboprophylaxis with LMWH or aspirin is suboptimal for VTE prevention. This may point to alternative thrombotic mechanisms in MM-VTE and further data in larger MM cohorts is needed to develop risk adapted strategies for prevention strategies for these patients.

Abstract Background Compared to the general population, patients with multiple myeloma (MM) have a 9-fold increased risk of developing venous thromboembolism (VTE). VTE is a preventable disease that causes death and morbidity. Thromboprophylaxis is a safe and effective way to decrease VTE in other high-risk populations (i.e. atrial fibrillation). Current guidelines recommend pharmacologic thromboprophylaxis in patients with MM receiving an immunomodulatory agent in the presence of additional VTE risk factors. However, putative risk factors vary across guidelines and lack validation. Recently, an attempt to validate the International Myeloma Working Group 2014 guidelines for thromboprophylaxis found current risk factors to be inadequate. Identification of risk factors for VTE in MM can allow for effective risk-stratification to clarify thromboprophylaxis in the MM population. We sought to identify risk factors for VTE in patients with MM. Methods We identified patients diagnosed with MM within the Veterans Administration Central Cancer Registry from September 1, 1999 and December 31, 2013 and followed them through October 2014. We excluded patients who did not receive MM-directed therapy within 6 months of diagnosis. Using a previously validated algorithm, (Thromb Res, 2015), we identified patients diagnosed with VTE after MM diagnosis by a combination of ICD-9 code for VTE plus pharmacologic treatment for VTE or IVC filter placement. We obtained information on baseline patient demographics, medical comorbidities, laboratory data, MM-directed therapy, and use of aspirin and/or warfarin. Univariate analyses identified the association between individual variables and VTE in the cohort. Clinically meaningful and significant associations were included in the multivariate model. Multivariate analysis was done using competing risks regression modeling. The study was approved by the Saint Louis VHA Medical Center and Washington University institutional review boards. Results A total of 3,384 patients comprised the final cohort of whom 414 developed a VTE. Patients who developed VTE were more likely to be younger (66.2 vs 68.5, p < .001), have a body mass index (BMI) ≥ 25 (p < .001), be diagnosed with MM prior to 2007 (p < .001), have a VTE before MM diagnosis (p < .001), have a lower comorbidities (p < .001), have received autologous stem cell transplant (ASCT) (p < .001), have received lenalidomide, thalidomide, or bortezomib (p < .001), and less likely to have received warfarin (p < .001). Among predefined risk factors, age (Hazard Ratio (HR) 0.99, 95% Confidence Interval (CI) 0.98-1.00, p = 0.02), VTE before MM diagnosis (HR 4.13, 95% CI 2.81-6.05, p < .001), heart failure (HR 0.70, 95% CI 0.51-0.96, p = 0.03), treatment with thalidomide (HR 2.02, 95% CI 1.63-2.50, p < 0.001), BMI ≥ 30 (HR 1.34, 95% CI 1.03-1.74, p = 0.03), and diabetes mellitus (HR 0.79, 95% CI 0.63-0.99, p = 0.04) were associated with VTE. After inclusion into multivariate analysis and adjusting for warfarin/aspirin use; age, BMI, year of MM diagnosis, VTE before MM, thalidomide, warfarin, and aspirin were all associated with VTE in MM (Table 1). Conclusion We identified several risk factors associated with VTE in MM. Incorporation of these risk factors into a MM-specific risk model has the potential to reduce risk of VTE in MM.

Background: Very low birth weight (VLBW) babies are at increased risk of a number of complications both immediate and late. Worldwide it has been observed that these babies contribute to a significant extent to neonatal mortality and morbidity. Aim of the study was to study the risk factors contributing to mortality in VLBW babies and to evaluate the morbidity pattern in these infants.Methods: A retrospective analysis of data retrieved from the case records of VLBW babies admitted in the NICU of Kilpauk Medical College between January 2015 to December 2015. Out of the 2360 intramural babies admitted during the study period, 99 babies were less than 1500 gms. The risk factors for these babies were analyzed for their association with the outcome. Data were statistically analyzed.Results: In present study, we found that sex of the baby, gestational age, obstetric score, birth asphyxia, pulmonary haemorrhage, ROP and presence of shock were found to be associated with increased mortality. By logistic regression analysis it was observed that birth weight of the baby (p value 0.002), duration of stay (p value 0.0006), presence of shock (p<0.0001), were the risk factors significantly associated with poor outcome.Conclusions: Among the maternal and neonatal factors analyzed in the study using logistic regression analysis, birth weight, duration of hospital stay and presence of shock were significantly related to poor outcome. Of these presence of shock was the single most important factor that predicted increased mortality.

Introduction Immunomodulatory agents (IMiD's) are associated with an increased risk of venous thromboembolism (VTE), particularly when combined with high dose steroids. Studies evaluating the use of lenalidomide-bortezomib-dexamethasone (RVD) and carfilzomib-lenalidomide-dexamethasone (KRD) in the frontline setting for multiple myeloma (MM) have reported a 6% and 24% incidence of thrombosis, respectively, despite primary thrombotic prophylaxis with aspirin (ASA) (Richardson, et al. Blood. 2010; Korde, et al. JAMA Oncol 2015). Recent data, including the Hokusai VTE Cancer Trial, have suggested that safety and efficacy of direct oral anticoagulants (DOACs) are preserved in the setting of treatment of solid malignancy-associated thrombosis (Raskob, et al. N Engl J Med. 2018; Mantha, et al. J Thromb Thrombolysis. 2017). Despite this data, there is limited experience and use of DOACs in prevention of thromboses in the setting of hematologic malignancies, specifically MM. After careful review of literature, since early 2018, we changed our clinical practice and routinely placed newly diagnosed MM (NDMM) patients receiving KRD at Memorial Sloan Kettering Cancer Center (MSKCC) on concomitant rivaroxaban 10 mg once daily, regardless of VTE risk stratification. In the following abstract, we present VTE rates and safety data for newly diagnosed MM patients receiving RVD with ASA vs. KRD with ASA vs. KRD with rivaroxaban prophylaxis. Methods This was an IRB-approved, single-center, retrospective chart review study. All untreated patients with newly diagnosed MM, receiving at least one cycle of RVD or KRD between January 2015 and October 2018 were included. The period of observation included the time between the first day of therapy until 90 days after completion of induction therapy. Patients were identified by querying the pharmacy database for carfilzomib or bortezomib administration and outpatient medication review of thromboprophylaxis with rivaroxaban or ASA. VTE diagnoses were confirmed by ICD-10 codes and appropriate imaging studies (computed tomography and ultrasound). Descriptive statistics were performed. Results During the observation period, 241 patients were identified to have received RVD or KRD in the frontline (99 RVD with ASA; 97 KRD with ASA; 45 KRD with rivaroxaban). Baseline characteristics were well distributed among the three arms, with a median age of 60 (30-94) in the RVD ASA arm, 62 (33-77) in the KRD ASA arm, and 60 (24-79) in the KRD rivaroxaban arm. Patients had International Staging System (ISS) stage 3 disease in 13% (N=13), 9.3% (N=9), and 11% (N=5) of the RVD ASA, KRD ASA, and KRD rivaroxaban arms, respectively. Median weekly doses of dexamethasone were higher in both KRD arms, 40 mg (20-40) vs. 20 mg (10-40) in the RVD ASA arm. The average initial doses of lenalidomide were 22 mg in the RVD ASA arm compared to 25 mg in both the KRD ASA and KRD rivaroxaban arms. After querying the pharmacy database, no patients were identified to have a history or concomitant use of erythropoietin stimulating agent (ESA) use. Treatment-related VTE's occurred in 4 patients (4.0%) in the RVD ASA arm, 16 patients (16.5%) in the KRD ASA arm, and in 1 patient (2.2%) in the KRD rivaroxaban arm. Average time to VTE was 6.15 months (Range 5.42, 9.73) after treatment initiation in the RVD ASA group, while it was 2.61 months (Range 0.43, 5.06) in the KRD ASA group and 1.35 months in the KRD rivaroxaban group. Minor, grade 1 bleeding events per the Common Terminology Criteria for Adverse Events (CTCAE) were identified in 1 (1.1%) patient in the RVD ASA arm, 5 (5.2%) patients in the KRD ASA arm, and 1 (2.2%) patient in the KRD rivaroxaban arm. Conclusion More efficacious MM combination therapies have been found to increase the risk of VTE when using ASA prophylaxis, indicating better thromboprophylaxis is needed. We found patients receiving ASA prophylaxis with KRD were more likely to experience a VTE and these events occurred earlier compared to patients receiving ASA prophylaxis with RVD. Importantly, the rate of VTE was reduced to the same level as ASA prophylaxis with RVD when low-dose rivaroxaban 10 mg daily was used with KRD, and without necessarily increasing bleeding risk. Our retrospective data support the development of prospective clinical trials further investigating DOAC use in thromboprophylaxis for NDMM patients receiving carfilzomib-based treatments.

Introduction: Chimeric antigen receptor modified T Cell (CAR-T) therapy is a rapidly developing treatment for patients with relapsed/refractory (R/R) B-cell non-Hodgkin lymphoma (NHL) or multiple myeloma (MM). Although this population is at high risk for thrombosis, there are few data about rates of venous thromboembolism (VTE) and arterial thromboembolism (ATE) with CAR-T. Additionally, treatment with anticoagulation is complicated because of the prevalence of thrombocytopenia following CAR-T. Our goal was to determine the incidence, associated risk factors, management and outcomes of VTE and ATE in the 60 days following CAR-T therapy. Methods: We performed a single-center, retrospective cohort study of all patients who received inpatient CAR-T cells at UCSF Medical Center between January 2018 and May 2020 for R/R NHL or MM as standard-of-care or on a clinical trial. The outcomes of incident VTE and ATE were identified by ICD-10 codes and medical record review. Patient characteristics, pre-existing thrombosis risk factors, laboratory results, medications, and major or clinically relevant non-major bleeding or recurrent thrombotic complications were obtained through chart review. We used descriptive statistics to delineate risk factors, incidence, management and outcomes of thrombotic events. Results: Ninety-one patients who underwent CAR-T therapy were included in the analysis, 37 with NHL and 54 with MM. For NHL, mean age was 63 (range 38-82), and 41% were women. For MM, mean age was 62 (range 33-77), and 50% were women. Patients with NHL were treated with either investigational or Federal Drug Administration-approved CD19-directed therapies, and patients with MM were treated with a variety of investigational B-cell maturation antigen-directed (BCMA) therapies. For thrombotic risk factors, 13% of patients with NHL had a history of VTE, 3% had a history of ATE, 27% had a BMI ≥30, 59% had a recent procedure including central venous catheter (CVC) placement, 14% had an intensive care unit (ICU) stay, and 22% had an infectious complication in the 30 days pre- or post-CAR-T. Forty-one percent of patients with NHL had neurotoxicity of any grade, and 59% had CRS of any grade. At 30 days, 57% had a complete response, 41% had a partial response, 3% had stable disease. For MM, 6% of patients had a pre-existing history of VTE, 2% had a history of ATE, 19% had a BMI ≥30, 96% had a recent procedure, 11% had an ICU stay and 19% had an infection. Seventeen percent had neurotoxicity, and 85% had CRS. Thirty-two percent of patients with NHL and 48% with MM received pharmacologic VTE prophylaxis while undergoing CAR-T. For those who did not receive VTE prophylaxis, thrombocytopenia was the reason for holding prophylaxis, which occurred in 51% and 50% of NHL and MM patients, respectively. In the 60 days post-CAR-T, 4 (11%) patients with NHL were diagnosed with VTE-3 pulmonary embolism (PE) and 1 lower extremity deep vein thrombosis (DVT) associated with a previously placed inferior vena cava filter. Four (7%) patients with MM were diagnosed with VTE-1 PE and 3 upper extremity DVTs associated with CVCs. Five out of these 8 (63%) patients had symptomatic VTE, while the remainder were incidental on PETCT. Mean time from CAR-T infusion to VTE diagnosis was 20 days (range 6-39 days). There were no documented ATEs. Six out of 8 (75%) were treated with therapeutic anticoagulation. Of those who were anticoagulated, 4 patients received direct oral anticoagulants and 2 received low-molecular-weight-heparin. Duration was 3 months in 3 patients, 11 days in 1, 150 days in 1, and indefinitely in 1 with atrial fibrillation. Among all 8 patients with VTE, there were no bleeding events or recurrent thromboses regardless of whether or not they received anticoagulation. Discussion: In this cohort of patients with R/R NHL or MM who received either CD19- or BCMA-directed therapies, almost 1 in 10 developed VTE in the 60 days post-CAR-T. This occurred in the context of a high prevalence of risk factors for thrombosis and low rates of pharmacologic prophylaxis. Among those who developed VTE, the majority were treated with therapeutic anticoagulation for at least 3 months, without documented bleeding or recurrent VTE. Our findings provide crucial information on a common complication that can inform patients, clinicians and researchers and should be expanded upon in larger, prospective studies to identify optimal preventive and therapeutic strategies.

Abstract Abstract 4735 Introduction: Symptoms of multiple myeloma (MM) and the adverse events (AEs) associated with MM treatment can be debilitating on many levels. A better understanding of the extent to which patients are affected and how this in turn impacts global health-related quality of life (HRQOL) can improve management of patients. Methods: A survey in 11 centers in the United Kingdom and Germany gathered, among other items, data on HRQOL, measured by the European Organization for Research and Treatment of Cancer's (EORTC) generic cancer and MM modules (QLQ-C30 and QLQ-MY20 scales), from a cross-section of patients with multiple myeloma at various phases of the disease. The QLQ-C30 is comprised of a global QOL domain, 5 functional and 3 symptom domains, and 6 AE items; the QLQ-MY20 includes scales for disease symptoms, treatment side-effects, future perspective and body image. This analysis aimed to explore the association between individual QOL scales (from QLQ-C30 and QLQ-MY20) and global QOL. Values for each scale range from 0 to 100; higher values indicate better HRQOL for the global, functional, future perspective and body image scales, and worse HRQOL for the AE items, symptom domains, disease symptoms and side-effects scales. Scoring of the QLQ-C30 and MY-20 scales was described previously by Fayers et al. [i] and Cocks et al. [ii] respectively. The distribution and correlations (Spearman) between the various scales was explored. Moreover, a multiple linear regression analysis was carried out to assess the association between individual scales and global QOL (from QLQ-C30) with the aim to identify those that independently impact global QOL. Each scale was first considered alone as a predictor of global QOL; those with a statistically significant association at a p-value ≤ 0.10 were included in a multiple regression model. This was then trimmed to exclude scales that became non-significant (p-value > 0.10). Results: The survey included 154 patients: 63.0% were male and the mean age was 66.4 (SD: 10.0). Mean time since diagnosis was 3.7 years (SD: 3.7), 51.9% were currently on treatment, and 42.9% had at least one prior line of MM therapy. The mean global QOL score was 60.1 (SD: 25.5), with the middle two quartiles of patients scoring between 41.7 and 83.3. Cognitive and emotional functioning scores had means near or above 80, suggesting that these aspects of HRQOL were less affected than role (62.9 (IQR: 33.3–100)), social (63.9(IQR: 33.3–100)) and physical functioning (68.7(IQR:53.3-93.3)). While body image scores were generally high (77.9 (IQR:66.7-100)), future perspective appeared to be relatively more affected (59.9 (33.3-77.8)). Patients’ HRQOL is most affected by pain and fatigue (based on symptom and AE scales of the QLQ-C30), with means above 30, followed by insomnia and dyspnoea with means above 20, while diarrhea and nausea/vomiting scales had the lowest mean scores (below 10). The Disease Symptom (23.3 (IQR:0-38.9)) and Side Effect scale scores (19.5 (IQR:7.4-29.6)) from the QLQ-MY20 were consistent with the AE and symptom scales from the QLQ-C30. All of the domains except diarrhea and nausea/vomiting individually showed at least moderate correlations with global QOL (Spearman correlations above 0.25 in absolute value), but also exhibited strong correlations between themselves. The final multiple regression model retained physical and social functioning, fatigue, disease symptoms (QLQ-MY20) and future perspective scales (QLQ-MY20), all of which had relatively similar strength of association with global QOL. Conclusion: This study demonstrates that the impact of MM and treatment AEs can be seen on various dimensions of patients’ HRQOL, particularly reduced physical and social functioning, future perspective and various disease symptoms such as bone pain (as captured by the disease symptoms scale of the QLQ-MY20) and fatigue.

Abstract Abstract 3340 Background. Immunomodulator drugs (IMiDs) are promising oral agents in Multiple Myeloma (MM); and MM that cannot benefit from novel agents, including IMiDs, only have 9 months survival. On the other hand IMiDs are associated with an increased risk of thromboembolic events (TE) in MM, and must be stopped when TE occurs with a potential shortened life expectancy. Although DVT (Deep Venous Thrombosis), including PE (Pulmonary Embolism), was primarily observed, arterial events were also described. Guidelines have proposed LWMH for VTE prophylaxis for patients that displayed greater than 2 risk factors of VTE. Studies have showed a decrease incidence of TE since a prophylaxis was mandatory; however TE remained despite use of LMWH. We sought to characterize and study the incidence of TE in MM treated with an IMiDs-based regimen and having LMWH as TE prophylaxis, and to determine risk factors for patients to develop TE. Method. MMVAR/IFM 2005–04 is a large multicenter, prospective, randomized, open-label, phase 3, EBMT and IFM combined study that compared VTD to TD for MM patients in first progression after autologous transplantation. Treatment comprised 8 cycles of bortezomib 1.3 mg/m2 IV bolus on days 1, 4, 8 and 11 of a 21-days cycle and then on days 1, 8, 15 and 22 of a 42-days cycle for 4 more cycles. In both arms, oral thalidomide was administered at 200 mg/day for 1 year with dexamethasone at 40 mg/day for 4 days every 3 weeks for 1 year. A TE prophylaxis was mandatory in both arms using enoxaparin 40 mg/day during one year. TTP was the primary end point. Response was assessed by EBMT criteria. Adverse events were graded by the NCI-CTCAE, Version 3.0. Results. The MMVAR trial was stopped because of superiority of VTD over TD at first interim analysis, as 157 relapsed were recorded out of 267 patients randomized in arm VTD (n=135) and arm TD (n=132), respectively. With a median follow-up of 27 months, the probability of achieving CR and CR+PR during the first year, the median TTP and PFS were greater in the VTD arm, although it did not translate into a better OS, yet. In the VTD and TD arms, the mean number of treatment cycles for the 12 cycles was 7.56 vs 9.93, respectively. Treatment was discontinued due to toxicity in 48 patients, including 8 (17%) related to occurrence of TE, and 33 patients died during the treatment period. There were 24 (8.9%) TE recorded, 12 in either arm; we have then decided to pool the 2 groups for the subsequent analysis. The characteristics of the MM with TE were not different from the overall population, 14 male/10 female, median age (range) was 63 (42–76) with 25% patients older than 65. The median (min-max) time from start of MMVAR to occurrence of TE was 3.4 months (0.3–11.9), not different in either arm. TE occurred in 16 (66%) vs. 8 (33%) patients in the first 4 months and after 4 months, respectively. 15 (62.5%) pts had at least some tumor burden reduction (minor response and better) at time of occurrence of TE, while 12.5% had progression of MM, 12.5% stable disease, and 12.5% were non evaluable. All TE occurred while pts were on LMWH prophylaxis since the initiation of the study treatment but one. The occurrence of TE impacted the treatment of MM as 16 (67%) pts did stop their IMiDs-based treatment, either transiently for 8 (33%) pts or definitely for 8 (33%) pts. The doses of the IMiDs were reduced for 5 pts when IMiDs were reintroduced. Overall only 5 pts had no change applied to their MM treatment while TE occurred. The occurrence of TE might have impacted response rate, CR rate, and the survival end points, TTP, PFS and OS. An update of this sub analysis will be presented at ASH with multivariate analysis to determine risk factors for occurrence of TE while on LMWH prophylaxis. Conclusion. Although LMWH is recommended to patients with high risk of TE, the optimal dose and duration of LMWH remains to be determined. More studies are needed to determine risk factors of TE in MM patients treated with IMiDs-based regimen, and to guide physician in their routine practice with the optimal TE prophylaxis.

Abstract Introduction Venous thromboembolism (VTE) is increasing in children, especially in the tertiary care setting. Hospital-associated VTE (HA-VTE) is a potentially preventable cause of major morbidity and mortality. However, the incidence of HA-VTE VTE is low in children Risk stratification tools may aid in identification of hospitalized high risk pediatric patients who may benefit from VTE prophylaxis. Methods We conducted a case-control study of pediatric patients with HA-VTE (21 years or younger at the time of diagnosis) admitted to the Johns Hopkins Hospital from 2008-2010. Cases were identified using ICD-9 codes for DVT and PE and verified by reviewing hospital records and radiologic imaging reports. HA-VTE was defined as: 1) VTE was diagnosed ≥48 hours after hospital admission without signs/symptoms of VTE on admission, or 2) VTE was diagnosed within 90 days of hospital discharge. Two contemporaneous controls matched for age, sex and admission unit were selected for each case. Records of cases and controls were reviewed for presence of a priori identified putative VTE risk factors at admission. Univariate and conditional multivariable logistic regression analyses with backward elimination were used to develop risk-prediction models. Based on results of univariate analysis, we sought to evaluate two multivariable models, one without length of stay (LOS) with relevance to assessment at admission, and one in which LOS was included with relevance to re-assessment after several days of hospitalization. All variables selected for the multivariable model were tested for interaction with a significance threshold level of p<0.2. Except for this, all hypothesis testing was two tailed and a p value of <0.05 was considered significant. Receiver operator curves (ROC) were constructed using risk factors on multivariate analysis. Results Table 1 lists the results putative risk factors by univariate analysis with a) significantly higher odds of VTE and b) higher odds of VTE but not statistically significant. In multivariable logistic regression analysis, central venous catheter (CVC), VTE predisposition and immobility or LOS >5 days were independently associated with HA-VTE. The combination of CVC and VTE predisposition with either immobility or LOS was predictive of HA-VTE (area under the curve for ROC of 76.6% and 80.6%, Table 2). Conclusion We found independently associated risk factors with that may potentially be used in a predictive model of HA-VTE in children. Further prospective validation studies of these and other risk factors may serve as the basis of future risk-stratified randomized control trials of primary prevention of pediatric HA-VTE.

15056 Background: Determination of patients (pts) with early stage disease who have a high risk for developing metastatic disease is crucial. We investigated the risk factors associated with metastases development in pts with operable gastric cancer. Patients and Methods: In this retrospective study, pts with stage I-III and non-metastatic stage IV gastric cancer diagnosed between 1990 and 2006 were evaluated. The medical records of all pts including patient characteristics, laboratory results, histopathological examinations, were reviewed. Logistic regression methods were used to determine the risk factors for developing metastasis and to calculate odds ratios (OR) with 95% confidence intervals (CI). Results: 184 pts (70% male, 30% female) were analyzed. The mean age ± standard deviation was 56.5±11.9. The mean age of female were higher than male (p=0.014). At the time of diagnosis, 13.6% of the pts had stage I, 19.0% had stage II, 53.3% had stage III, and 14.1% had non-metastatic stage IV disease. The tumors were distally localized in 80% of the cases. Median follow-up period was 35 months. During follow up, 51 pts developed metastases. Median time to metastases development was 14 months. Overall survival was shorter in pts who developed metastasis than those who did not. (20 months vs. not reached, respectively, p=0.002). In univariate analyses, stage (p=0.020), tumor localization (p=0.006), extracapsular lymphatic extension (ELE) (p<0.001), the number of metastatic lymph nodes (p=0.001), CEA level (p<0.001), lymphovascular invasion (LVI) (p=0.001), and perineural invasion (p=0.007) were associated with metastasis development. In multivariate analysis, elevated CEA levels (p=0.009; OR: 2.8; CI 95%: 1.29–6.19), LVI (p=0.041; OR: 2.2; CI 95%: 1.03–4.64) and ELE (p=0.029; OR: 2.3; CI 95%: 1.09–4.78) were associated with increased risk of metastasis development while distal localization (p=0.038; OR: 0.42; CI%: 0.18–0.95) was associated with decreased risk in pts with gastric cancer. Discussion: In pts with early stage or locally advanced gastric cancer, elevated CEA levels, LVI, proximal localization and ELE were associated with increased risk of developing metastasis. Aggressive treatment options and closer follow up should be considered for pts with these risk factors. No significant financial relationships to disclose.

The Impact

ObjectivesLow testosterone levels in men have been associated with cardiovascular risk factors and atherosclerosis and lately also an increased risk of both cardiovascular disease (CVD) and all-cause mortality. As arterial CVDs and venous thromboembolism (VTE) have been shown to share common risk factors, the purpose of the present study was to determine the impact of endogenous sex hormone levels on the incidence of VTE in a cohort of men.DesignA prospective, population-based study.MethodsSex hormone measurements were available in 1350 men, aged 50–84, participating in the Tromsø study in 1994–1995. First, lifetime VTE-events during the follow-up were registered up to September 1 2007.ResultsThere were 63 incident VTE-events (4.5 per 1000 person-years) during a mean of 10.4 years of follow-up. Age was significantly associated with increased risk of VTE; men 70 years or older had a 2.5-fold higher risk of VTE (HR 2.47, 95% CI 1.19–5.12), compared with those between 50 and 60 years of age. In age-adjusted analyses, endogenous sex hormones levels were not associated with risk of VTE; for each s.d. increase, hazards ratios (95% CI) were 1.06 (0.83–1.35) for total testosterone, 1.02 (0.79–1.33) for free testosterone, and 1.27 (0.94–1.71) for ln-estradiol. In dichotomized analyses comparing men in the lowest total and free testosterone quartile with men in the higher quartiles, hypoandrogenemia was not associated with risk of VTE.ConclusionsIn this population-based study of middle-aged and older men, endogenous sex hormone levels were not associated with 10-year risk of VTE.

Abstract Background Richter's transformation (RT) refers to the development of an aggressive lymphoma in patients with chronic lymphocytic leukemia (CLL) or small lymphocytic leukemia (SLL). Roughly, 2-10 % of patients with CLL develop RT most often as diffuse large B-cell lymphoma (DLBCL) or Hodgkin lymphoma (HL). Aim This study aimed to assess the incidence rate and risk factors for RT for patients with CLL in a nationwide cohort. Furthermore, we want to assess prognostic risk factors for patients with RT. Methods All patients diagnosed with CLL in Denmark between 2008 and 2016 were included in this study. Clinical data was retrieved from the Danish National CLL Registry (DCLLR), whereas all histologically verified DLBCL, HL and/or transformation diagnoses for patients with CLL were retrieved from the Danish National Pathology Registry. Patients were followed from date of CLL diagnosis until date of RT, death or end of follow-up, whichever came first. The time to RT was estimated as cumulative incidence considering death as a competing risk. Stepwise Cox analysis with backward elimination was applied to identify independent risk factors for RT in patients with CLL. Results A total of 3771 CLL patients were identified, and followed for 14165 person-years. With a median follow-up of 4.3 (IQR (2.4;6.6)) years, 120 (3%) CLL patients had a transformation diagnosis, of which 4 patients were excluded due to misdiagnosis. DLBCL accounted for 78/116 (67%) cases, HL for 15/116 (13%) cases and one patient presented with both DLBCL and HL. In the remaining 22/116 (19%) cases the subtype of the transformation was either unspecified or unclassified RT. The median time to RT was 3.4 (IQR (1.8;5.7)) years from CLL diagnosis and the median overall survival (OS) after development of RT was 4.9 (IQR (0.7;8.4)) years. The cumulative incidence of RT, calculated by Aalen-Johansen estimator, at 5 and 8 years post-CLL diagnosis were 3.3% and 7.9% respectively (Figure 1). The annual crude incidence rate of RT was approximately 0.7% per year for all CLL patients. In all, 918 (24%) patients received CLL-related treatment, of whom 59 (6.4%) patients developed RT, resulting in a cumulative incidence of RT of 7% after 5 years and 11% after 8 years. At the time of CLL diagnosis, patients treated for CLL prior to RT diagnosis had a worse median OS (1.49 years) compared to RT patients who were untreated for CLL (6.16 years). In the univariate analysis, RT was significantly associated with male gender, advanced Binet stage (B or C), unmutated IGHV status (CLL-U), elevated beta-2-microglobulin (>3.5 mg/L) and elevated lactate dehydrogenase (>205 U/L). Of cytogenic aberration, deletion 13q (del(13q)) had a protective effect on the risk of RT, whereas deletion 11q (del(11q)) and deletion 17p (del(17p)) increased the risk. In the multivariable model, advanced Binet stage (HR 2.86 (1.82;4.51), p<0.001), del(17p) ((HR 3.74 (2.12;6.61), p<0.001) and CLL-U ((HR 2.30 (1.46;3.63), p<0.001) showed an independent correlation with development of RT. ZAP70 and CD38 were excluded from statistical analyses due to incomplete data and high inter-laboratory variation. Among RT patients, CLL-U, trisomy 12 and del(17p) at CLL diagnosis as well as ECOG Performance Status (PS) (i.e. PS≥1) at time of RT diagnosis correlated with poor OS in univariate analysis. Both del(17p) and PS≥1 were independently associated with an increased risk of death in a multivariable analysis (HR 2.9, (1.1;7.7), p=0.04 and HR 3.0, (1.0;3.1), p=0.05, respectively). Conclusions To the best of our knowledge, we here report the largest study on RT assessing nationwide data of consecutive patients diagnosed with CLL. The incidence of RT in this unselected population was 3.3% after 5 years while the median OS for patients from time of RT was 4.9 years. Advanced Binet stage, del(17p) and CLL-U were significantly and independently associated with an increased risk of RT. Del(17p) at CLL diagnosis and PS≥1 at RT diagnosis were significant predictors for death for patients with RT. For patients diagnosed with RT prior to any CLL treatment, a less severe disease course with a median OS of 6.16 years was demonstrated. Contrary, the median OS for patients receiving prior CLL treatment was 1.49 years. Thus, assessment of different treatment options for patients developing RT based on whether they have received prior CLL treatment or not is warranted. Figure 1. Figure 1.
