Abstract Background: Cancer patients are at increased risk of both venous thromboembolism (VTE) and bleeding, but real world bleeding rates with contemporary anticoagulants are not known. Purpose: To describe the incidence of major bleeding (MB) in VTE patients treated with rivaroxaban, and to compare differences in MB incidence and characteristics among patients with active cancer, history of cancer, and no current or past cancer. Methods: We queried over 10 million electronic medical records (EMRs) from the United States Department of Defense healthcare system from November 2, 2012 to September 30, 2015 to identify MB events in VTE patients treated with rivaroxaban. The Cunningham algorithm was used for identifying MB, and VTE was determined by diagnosis codes. Presence of cancer was assessed from 5 years prior to index rivaroxaban exposure through end of study, and categorized by active cancer, history of cancer, and no cancer. Active cancer was defined by one of the following: 1) a metastatic diagnosis code within 6 months prior to or overlapping with rivaroxaban exposure, 2) chemotherapy and/or radiation codes within 6 months prior to rivaroxaban exposure, 3) cancer-related surgery overlapping with rivaroxaban exposure, or 4) leukemia and/or indolent lymphoma codes at any point within the entire assessment window. History of cancer was defined as the presence of any cancer diagnosis within the 5-year baseline period not meeting the definition of active cancer. Patients with active cancer or history of cancer were further categorized by cancer site/type. Incidence, outcomes, demographics, and bleeding risk scores were evaluated by cancer status. A Cox proportional hazard model was used to assess the association between cancer status and rate of MB adjusting for baseline characteristics. Results: The study population comprised 9,638 VTE patients on rivaroxaban, including 1,728 (17.9%) with active cancer, 1,548 (16.1%) with history of cancer and 6,362 (66.0%) with no cancer. Of these, 130 (1.3%) experienced MB. After stratifying by cancer status, MB occurred at a rate of 2.61 (95% CI 1.80-3.78) per 100 person-years in those with active cancer, 3.18 (95% CI 2.17-4.67) per 100 person-years in those with history of cancer, and 2.25 (95% CI 1.80-2.81) per 100 person-years in those with no cancer. No significant difference in the incidence of MB was found between those with cancer (active or history) and those without cancer (HR 1.01; 95% CI 0.70-1.47, p-value 0.94) after adjusting for age, sex, and baseline comorbidities. Neither history of cancer nor active cancer when independently compared to no cancer was significantly associated with MB after multivariate adjustment. MB rates varied notably by cancer site. Additional key findings are presented in Table 1. Conclusion: In this large United States Department of Defense cohort study of rivaroxaban users treated for VTE, incidence of MB is relatively low and not significantly different between cancer and non-cancer patients. Fatal outcomes associated with bleeding hospitalization were also uncommon across all the cancer groups. These data should provide assurance to oncology providers regarding the safety of rivaroxaban use in the real-world setting.

Introduction The utility of D-dimer testing as a screening tool for venous thromboembolism (VTE) exclusion is uncertain in cancer patients, due to low specificity. A new fibrin assay independent of inflammation and hypercoagulability has been recently developed. Methods Non-anticoagulated patients with clinically suspected VTE from the FSET study (NCT02523937) had VTE diagnosed using the standard diagnostic algorithms, including a 3-month clinical follow-up. In all patients, the fibrin assay prototype (Diagnostica Stago) was performed at the time of admission. We divided the patients included in the FSET study in 3 groups: (i) history of cancer, (ii) active cancer (known or unequivocal evidence), and (iii) no cancer. We sought to evaluate the performances of the fibrin assay compared with the D-Dimer or age-adjusted D-Dimer test to exclude VTE in cancer patients. Results Of the 863 included patients, 83 (9.6%) had either a history of cancer (n=30) or an active cancer (known or unequivocal evidence) (n=53). The prevalence of VTE was of 3.3% and 20.7%, respectively, vs 7.6% in non-cancer patients. Patients with a history of cancer had most frequently breast cancer (40%) and genito-urinary cancer (23.3%).Of the 53 patients with active cancer (known or unequivocal evidence), 9.4% had a recurrence, and most patients had metastatic cancers (52.8%). Those patients had most frequently lung cancer (26.4 %) and breast cancer (15.1 %). Overall, 18.9% of patients with known cancer were treated with chemotherapy, 3.7% with immunotherapy and 13.2% with hormonotherapy. In the present study, 9.4% of patients with known active cancer had a high VTE probability vs 2.8% in patients without cancer. Overall, given a high VTE clinical probability score in a substantial number of cancer patients on one hand, and the DDi level most likely above the cut-off value for VTE exclusion in those with a low-to-moderate probability on the other hand, cancer patients required more often imaging to confirm or exclude VTE diagnosis, 68.7% in patients with a history of cancer or with active cancer versus 42.6% in patients without cancer, respectively. The fibrin assay specificity for VTE was highly increased compared to D-Dimer test, associated with a 100% negative predictive value [95% CI 89-100%] and [95% CI 83-100%] respectively in patients with a history of cancer or with active cancer. Fibrin assay allowed ruling out VTE in a much higher proportion of patients compared to the 500 μg/L D-Dimer cut-off / or age-adjusted D-Dimer cut-off strategy, irrespectively of clinical probability assessment: 76.7% vs 40%/60% in patients with a history of cancer, 39.6% vs 17.0%/22.6% in patients with active cancer, 76.7% vs 54.5%/60.9% in non-cancer patients. Conclusion The new fibrin assay demonstrated an increased specificity compared to DDi or age-adjusted cut-off strategy with excellent negative predictive value, resulting in safely excluding more than 25% VTE compared to DDi or more than 15% VTE compared to age-adjusted cut-off in patients with a history or an active cancer; thus reducing imaging testing in these patients, irrespectively of the clinical probability. These promising results require further confirmation in future trials.

10572 Background: Several reports have suggested that cancer patients are at increased risk for contracting severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and suffering worse coronavirus disease 2019 (COVID-19) outcomes. However, little is known about the impact of cancer status on presentation and outcome. Here, we report on the association between cancer status and survival in hospitalized patients who tested positive for SARS-CoV-2 during the height of pandemic in New York City. Methods: Of the 6,724 patients who were hospitalized at NYU Langone Health (3/16/20 - 7/31/20) and tested positive for SARS-CoV-2, 580 had either active cancer (n = 221) or a history of cancer (n = 359). Patients were classified as having active malignancy if they either received treatment within six months of their COVID-19 diagnosis or they had measurable disease documented at the time of their hospitalization. Patients were categorized as having a history of cancer if there was no evidence of measurable disease or there were no treatments administered within six months of their COVID-19 diagnosis. We compared the baseline clinicodemographic characteristics and hospital courses of the two groups, and the relationship between cancer status and the rate of admission to the intensive care unit (ICU), use of invasive mechanical ventilation (IMV), and all-cause mortality. Results: There was no differences between the two groups in their baseline laboratory results associated with COVID-19 infection, incidence of venous thromboembolism, or incidence of severe COVID-19. Active cancer status was not associated with the rate of ICU admission ( P = 0.307) or use of IMV ( P = 0.236), but was significantly associated with worse all-cause mortality in both univariate and multivariate analysis with ORs of 1.48 (95% CI: 1.04-2.09; P = 0.028) and 1.71 (95% CI: 1.12-2.63; P = 0.014), respectively. Conclusions: Active cancer patients had worse survival outcomes compared to patients with a history of cancer despite similar COVID-19 disease characteristics in the two groups. Our data suggest that cancer care should continue with minimal interruptions during the pandemic to bring about response and remission as soon as possible. Additionally, these findings support the growing body of evidence that malignancy portends worse COVID-19 prognosis, and demonstrate that the risk may even apply to those without active disease.

Abstract Background Patients with a prior history of cancer are commonly excluded from clinical trial. Increasing number of studies implied that a prior cancer did not adversely affect the clinical outcome among various types of cancer patients. However, the impact of prior cancer on survival of larynx cancer patients remains largely unknown. The aim of this study was to evaluate the prevalence of prior cancer and assess its impact on survival of patients diagnosed with larynx cancer. Methods Patients with larynx cancer as the first or second primary malignancy diagnosed from 2004 to 2015 were extracted from the Surveillance, Epidemiology, and End Results (SEER) database. Propensity score matching (PSM) was conducted to balance baseline characteristics. Kaplan-Meier method, multivariate Cox proportional hazard model, and multivariate competing risk model were performed for survival analysis. Results A total of 24,812 eligible patients with larynx cancer were included in the study, wherein a total of 2436 patients (9.8%) had a prior history of cancer. Prostate (36%), lung and bronchus (10%), urinary bladder (7%), and breast (6%) were the most common types of prior cancer. A prior cancer history served as a risk factor for overall survival (AHR =1.30; 95% CI [1.21–1.41]; P < 0.001) but a protective factor for cancer-specific mortality (AHR = 0.83; 95% CI [0.72–0.94]; P = 0.004) in comparison with those without prior cancer. The subgroup analysis showed that a prior history of cancer adversely affected overall survival of patients with larynx cancer in most subgroups stratified by timing and types of prior cancer, as well as by different clinicopathologic features. Conclusion Our study indicated an adverse survival impact of a prior history of cancer on patients with larynx cancer. Except for a few particular prior cancer, clinical trials should be considered prudently for laryngeal cancer patients with prior cancers.

e19054 Background: Uninsured patients diagnosed with cancer receive fewer screenings, frequently present with later-stage cancer, and are often unable to access standard-of-care treatment when compared to insured patients. We previously performed a study demonstrating that uninsured patients with cancer histories have higher levels of comorbidity. However, there is limited data on long-term studies describing comorbid chronic conditions among uninsured cancer patients. Here we examine socioeconomic factors and comorbid chronic conditions in uninsured patients with a cancer history over a period of three years. Methods: A retrospective chart review was conducted from 10 free clinics around the Tampa Bay region. Patients with any documented history of cancer who utilized a free clinic between 2016 and 2018 were included. Patients with no documentation of cancer history were excluded. Demographics, chronic disease parameters, and Charlson Comorbidity Index (CCI) scores were extracted and analyzed. Results: Between 2016 – 2018, a total of 17,003 uninsured patients were treated at 10 free clinics. Of these patients, 455 (2.7%) had a documented history of cancer, 9021 (53.1%) had no history of cancer, and 7527 (44.3%) had no documentation of cancer in their charts. Cancer patients were mostly women (305, 67.0%) and the average age was 55.2 years. Patients with cancer had significantly higher CCI scores compared to patients without cancer in 2016 (3.0 [2.0 SD] versus 0.94 [1.2 SD]), 2017 (2.71 [2.38 SD] versus 0.93 [1.26 SD]), and 2018 (3.27 [2.22 SD] versus 1.08 [1.26 SD]), p < 0.001. Patients with a cancer history were also more likely to be current drinkers (16.9% versus 13.0%) or smokers (17.8% versus 11.0%) compared to patients without a history of cancer. Conclusions: The results demonstrate that uninsured cancer patients consistently have higher levels of chronic disease and comorbidity compared to uninsured patients without a cancer diagnosis. This study increases awareness of the disease burden and mortality risk specific to uninsured cancer survivors which could inform free clinics and volunteer providers to better address the needs of this vulnerable population.

Abstract Background In hospitalized patients with COVID-19, active cancer has been identified as a potential risk factor for adverse cardiovascular outcomes, including thrombosis. However, the impact of COVID-19 on outcomes in patients with a remote history of cancer is poorly understood. We evaluated hospitalized patients with a history of remote cancer and COVID-19 to examine whether a history of cancer contributes to 30-day major adverse cardiovascular outcomes among patients with COVID-19. Methods Using a retrospective cohort of 1114 patients from CORONA-VTE (Registry of Arterial and Venous Thromboembolic Complications in Patients With COVID-19), we looked at 399 hospitalized patients diagnosed with polymerase chain reaction (PCR)-confirmed COVID-19 within a large heath care network that consists of two large academic medical centers and several community hospitals. Twenty-six patients with active cancer or receiving cancer treatment within 1-year of COVID-19 diagnosis and five patients with unknown cancer history were excluded. We assessed 46 patients with a history of cancer and 322 patients without any history of cancer. The primary endpoint was the frequency of adjudicated major adverse cardiovascular outcomes, defined as myocardial infarction, stroke, pulmonary embolism, deep vein thrombosis, and mortality. Results Among the 46 hospitalized patients with COVID-19 and a history of cancer, 23.9% were non-white and 43.48% women. Compared to patients without any history of cancer, patients with a history of cancer were older (median 59.0 vs. 75.5 years, p&lt;0.001) and had higher BMI (median 26.4 vs. 29.6 kg/m2, p&lt;0.05). Patients with a history of cancer had higher rates of underlying CVD than those without (42.4% vs. 23.2%). Rates of major adverse cardiovascular events were similar in patients with and without a history of cancer (28.3% vs. 23.6%, respectively). Those with a history of cancer had a higher mortality rate (28.9% vs. 11.2%, p&lt;0.05). Acute Respiratory Distress Syndrome (ARDS) and preexisting CVD were independently associated with mortality in this patient cohort (OR 19.7, 95% CI 7.5–51.7 and OR 2.9, 95% CI 1.2–6.9). History of remote cancer was not independently associated with mortality (OR 2.39, 95% CI 0.93–6.15, p=0.07). Conclusion Our findings indicate that a history of remote cancer is not independently associated with increased mortality in hospitalized COVID-19 patients. These data suggest that the cause of death among hospitalized patients with COVID-19 and history of cancer is most likely multifactorial, with a strong contribution from cardiovascular disease.

Abstract Background Little is known about the prevalence of a history of cancer and its impact on clinical outcome in mitral regurgitation (MR) patients undergoing transcatheter mitral valve repair (TMVR). Objectives The purpose of this study is to investigate the prevalence of cancer, baseline inflammatory parameters, and clinical outcome in MR patients undergoing TMVR. Methods Consecutive patients undergoing a MitraClip procedure were enrolled, and the patients were stratified into two groups: cancer and non-cancer. Baseline complete blood counts (CBC) with differential hemograms were collected prior to the procedure to calculate the platelet-to-lymphocyte ratio (PLR) and neutrophil-to-lymphocyte ratio (NLR). All-cause death within a one-year was examined. Results In total, 82 out of 446 patients (18.4%) had a history of cancer. Cancer patients had a significantly higher baseline PLR [181.4 (121.1–263.9) vs. 155.4 (109.4–210.4); P = 0.012] and NLR [5.4 (3.5–8.3) vs. 4.0 (2.9–6.1); P = 0.002] than non-cancer patients. A Kaplan–Meier analysis revealed that cancer patients had a significantly worse prognosis than non-cancer (estimated 1-year mortality, 20.2 vs. 9.2%; log-rank P = 0.009), and multivariable analyses of three models showed that cancer history was an independent factor for 1-year mortality. Patients who died during follow-up had a significantly higher baseline PLR [214.2 (124.2–296.7) vs. 156.3 (110.2–212.1); P = 0.007] and NLR [6.4 (4.2–12.5) vs. 4.0 (2.9–6.2); P < 0.001] than survivors. Conclusions In MitraClip patients, a history of cancer was associated with higher inflammatory parameters and worse prognosis compared to non-cancer patients. Graphical Abstract Central Illustration. Clinical outcomes and baseline PLR and NLR values accord-ing to one-year mortality. (Left) Patients who died within the follow-up period had a significantly higher baseline PLR (214.2 [124.2–296.7] vs 156.3 [110.2–212.1]; P = 0.007) and NLR (6.4 [4.2–12.5] vs 4.0 [2.9–6.2]; P < 0.001) than patients who survived. PLR, platelet-to-lymphocyte ratio; NLR, neutrophil-to-lymphocyte ratio (Right) A Kaplan-Meier analysis revealed that cancer patients had a significantly worse prognosis than non-cancer patients (estimated one-year mortality, 20.2 vs 9.2%; log-rank P = 0.009).

Abstract Background Although previous studies have reported that patients with a history of cancer have 2–3 times higher risks for acute coronary syndrome (ACS), morphological culprit plaque characteristics in ACS patients with a cancer history and their relations with clinical outcomes remain unknown. Methods The Kobe University ACS-OCT registry is a multi-center registry of consecutive ACS patients who underwent OCT-guided emergent PCI in Japanese four centers. All patients were categorized into the patients without a history of cancer (non-cancer), those with a history of cancer who diagnosed more than one year before ACS (historical), and those with ongoing cancer treatment or diagnosis within one year before ACS (current). ACS culprit lesions were classified into plaque rupture (PR), plaque erosion (PE), and calcified nodule (CN) according to morphological features by OCT and clinical events were collected after the onset of ACS. Results Among 436 patients, 63 patients (14.4%) had a history of cancer or ongoing treatment of cancer (cancer patients). Cancer patients were significantly older than non-cancer patients (73.4±9.4 vs. 66.9±12.9, p=0.001), and non-ST segment elevation ACS was more frequently observed in cancer patients than in non-cancer patients (57.1% vs. 43.2%, p=0.039). Regarding the ACS culprit lesion, the frequency of PR was significantly lower and the frequencies of PE and CN were significantly higher in the cancer patients than in the non-cancer patients (Figure A1). The cumulative incidence of major adverse cardiovascular event (MACE: composite of cardiac death, non-fatal myocardial infarction, and any revascularization, stroke, and heart failure with admission) after the onset of ACS in cancer patients was significantly higher than that in the non-cancer patients (Figure B1). When the cancer patients were categorized into the historical and the current cancer patients, the frequency of PE was higher in the current and the historical cancer patients than the non-cancer patients. Also, the incidence of CN was significantly higher in the historical cancer patients than others (Figure A2). The cumulative incidence of MACE was significantly higher in the current cancer patients, followed by historical and non-cancer patients (Figure B2). Cox regression analyses demonstrated that the non-PR lesion (hazard ratio (HR) 0.65, 0.46–0.94, p=0.021), patients with multivessel disease (HR 2.55, 1.79–3.64, p&lt;0.001), older patients (HR 1.02, 1.00–1.03, p=0.043) were independently associated with MACE after ACS. Moreover, multivariate analysis demonstrated that cancer history (HR 4.64, 2.34–9.21, p&lt;0.001) and non-ST segment elevation ACS (HR 0.66, 2.34–9.21, p=0.038) were independently associated with non-PR lesion. Conclusions The present study revealed the difference in morphological plaque characteristics between cancer and non-cancer patients, which might explain potential underlying mechanisms for worse outcomes in cancer patients.

Background: Patients with cancer are at elevated risk for venous thromboembolism (VTE). Active cancer contributes a 4-7 fold increased risk for VTE; however, the incidence of VTE stratified by subpopulations of patients diagnosed with cancer, especially race/ethnicity, is uncertain. Objective: Describe the incidence of VTE among adult patients (age ≥ 18 years) with a cancer diagnosis in Oklahoma County, OK according to age, gender, race, and cancer type. Methods: In collaboration with the Centers for Disease Control and Prevention, we established a population-based surveillance system for VTE in Oklahoma County, OK between April 1, 2012-March 31, 2014 to estimate the incidences of first-time and recurrent VTE events. The Commissioner of Health made VTE a reportable condition and delegated surveillance-related responsibilities to the University of Oklahoma, College of Public Health. Active surveillance involved reviewing imaging studies (e.g., chest computed tomography and compression ultrasounds of the extremities) from all inpatient and outpatient facilities in the county and collecting demographic, treatment and risk factor data on all VTE case-patients. Patients were linked to the Oklahoma Central Cancer Registry. Any patient with a cancer diagnosis since 1997, excluding basal or squamous cell carcinoma, were included in the population-at-risk. Active cancer was defined as metastatic or a diagnosis ≤6 months before their VTE diagnosis. Poisson regression was used to estimate incidence rates (IRs) and 95% confidence intervals (CIs), which are reported per 1,000 person years (PY). Estimates with &lt;10 events were suppressed. Results: Among all patients aged ≥18 years with a cancer diagnosis since 1997, 1.5% (n = 881) had a VTE event during the 2-year surveillance period. The overall annual age-adjusted incidence of VTE among those with cancer was 6.8 per 1,000 PY (95% CI: 5.81, 7.95). The demographic-specific incidence rates are summarized in Table 1. The VTE incidence did not significantly differ by sex. When stratified by age, annual VTE incidence was similar among those aged 18-39 years (6.1/1,000 PY, 95% CI: 4.35, 8.61), 40-59 years (6.2/1,000 PY, 95% CI: 5.4, 7.14), and 60-79 years (7.2/1,000 PY, 95% CI: 6.55, 7.90), however, the incidence was significantly higher (p&lt;0.05) in those aged 80+ years (10.1/1,000 PY, 95% CI: 8.77, 11.61). When patients with a cancer diagnosis were stratified by race/ethnicity, non-Hispanic blacks had the highest VTE incidence (11.7/1,000 PY, 95% CI: 10.00, 13.59), followed by Hispanics (8.0/1,000 PY, 95% CI: 5.66, 11.44), non-Hispanic whites (6.9/1,000 PY, 95% CI: 6.41, 7.48), other non-Hispanic/unknown (5.8/1,000 PY, 95% CI: 3.45, 9.85), and non-Hispanic Native Americans (2.6/1,000 PY, 95% CI: 1.39, 4.79). VTE incidence was highest among those with active cancer or a history of cancer within the past three years, after which it appeared to decrease. When stratified by primary cancer type, VTE incidence was highest among those with brain cancer (16.6/1,000 PY, 95% CI: 11.06, 25.04) and lowest among those with prostate cancer (5.2/1,000 PY, 95% CI: 4.20, 6.44). As shown in Table 2, when stratified by cancer type, the incidence of VTE was higher (non-overlapping CIs) among those with active cancer compared to those with a history of cancer &gt;6 months for several tumor types. Discussion: The incidence of VTE among those with cancer differs by race/ethnicity, with non-Hispanic blacks bearing the highest burden of disease. The risk of VTE persists and is particularly elevated up to three years after a cancer diagnosis.
