Abstract Introduction. Upper extremity deep vein thrombosis (UEDVT) is a relatively uncommon event with potentially serious complications. Its optimal treatment and clinical outcomes are not well studied. The objective of our study was to assess the safety and efficacy of a standardized management protocol for UEDVT as well as its long term complications. Patients and methods. We conducted a prospective cohort study at 5 Canadian centres and enrolled adult patients with a symptomatic UEDVT confirmed by compression ultrasound involving the brachial or more proximal veins, with or without a pulmonary embolism (PE). Exclusions included pregnancy, dialysis catheter thrombosis, active or high bleeding risk, platelet count <100x109/L, creatinine clearance < 30 ml/min, on warfarin for other indications, hemodynamically unstable PE, acute leukemia or undergoing a stem cell transplant within 3 months, geographical inaccessibility, life expectancy <3 months or treatment with low molecular weight heparin (LMWH) or warfarin for more than 7 days since diagnosis. Standardized treatment regimens were as follows: spontaneous or central venous catheter (CVC)-related UEDVT were treated with dalteparin at therapeutic doses for at least 5 days followed by warfarin adjusted according to INR results. Spontaneous UEDVT was treated for at least 6 months and CVC-related events were treated for at least 3 months or for as long as the line remained in place and for at least 1 month after line removal. Cancer patients with non CVC-related UEDVT were treated using dalteparin alone for a minimum of 6 months. Main outcomes were objectively documented venous thromboembolism (VTE) recurrence, major bleeding and death. All outcomes were centrally adjudicated. Patients were followed for 2 years. Data was analyzed using descriptive statistics. Survival data was analyzed using the Kaplan-Meier Method. Post-hoc analyses were conducted comparing CVC and spontaneous events. The study was approved by all institutional review boards. Results. Between 2009 and 2012, we enrolled 141 patients: 75 with spontaneous and 66 with CVC related UEDVT. Mean age was 51 years; 55% were males. The population characteristics are shown in the Table. The 2 year cumulative incidence of VTE recurrence was 3.5% (95% CI 1.5-8), of major bleeding was 2.8% (95% CI 1.1-7.1) and of death was 22% (95% CI 16-29.5). VTE recurrence rate was no different for spontaneous vs. CVC-related groups (4% vs. 3%; Log-Rank P = 0.690; Figure). Conclusion. The use of a standardized management protocol for patients with UEDVT results in a low risk of VTE recurrence and major bleeding at 2 years of follow up, in both CVC-related and spontaneous UEDVT.

Abstract Introduction Upper extremity deep vein thrombosis (UEDVT) represents up to 10% of cases of venous thromboembolism (VTE) and is frequently associated with central venous catheter (CVC) placement in patients receiving chemotherapy for cancer. UEDVT may be treated with low molecular weight heparin (LMWH) either as monotherapy or subsequently transitioned to warfarin as we have previously shown (Kovacs 2007). Whereas for non-cancer VTE rivaroxaban is at least as efficacious and safe as warfarin, the latter is problematic in cancer patients and direct oral anticoagulants (DOACs) such as rivaroxaban have not been studied to date in this setting. In this study weevaluated thesafety and efficacy of rivaroxaban in the treatment of UEDVT secondary to CVC in patients with cancer. Methods We conducted a multicentre prospective cohort study at 3 centres in Canada between December 2012 and January 2016. We enrolled patients ≥18 years of age with active malignancy and symptomatic proximal UEDVT (axillary or more proximal) with or without pulmonary embolism (PE), associated with a CVC. Exclusion criteria included dialysis catheters, active bleeding, platelet count <75 x 109/L, creatinine clearance <30 mL/min, other anticoagulants, PE with hemodynamic instability, inability to infuse through the catheter after a trial of intraluminal thrombolytic therapy (tissue plasminogen activator,tPa), patients with acute leukemia, patients with multiple myeloma awaiting bone marrow transplant within 3 months, thrombosis involving the brachial,basilic or cephalic veins only, treatment for >7 days with other anticoagulant, need for dual antiplatelet therapy (recent stent), or concomitant use of P-glycoprotein and CYP3A4 inhibitors. Primary objective was an estimate of the proportion of catheter survival at 3 months, defined as infusion failure that does not respond to 2 mg oftPa. Secondary objectives included recurrence of DVT, PE, major bleeding, clinically relevant non-major bleeding (CRNMB) and death. All events were independently adjudicated. Patients were treated with rivaroxaban at a dose of 15 mgpo bid for 3 weeks, followed by 20 mgpo daily for 9 more weeks (minimum 12 weeks).tPa (oralteplase) for management of blocked lines was allowed. Patients were followed clinically for 12 weeks to assess for clinical events including recurrent DVT and/or PE, major bleeding and CRNMB, and by phone at 6 months. Results We included 70 patients (47[67%] women) with a mean age of 54.1 years. DVTs were diagnosed by ultrasound in 68 (97%) patients, and most commonly involved the subclavian (n=55, 79%) and axillary (n=49, 70%) veins, followed by the internal jugular, brachial, brachiocephalic and external jugular veins. Peripherally inserted central catheters (PICC) were most common (n=54, 77%), followed by port-a-cathlines (n=16, 23%). Types of active malignancy included breast (n=29, 41%), colon (n=8, 11%), colorectal (n=5, 7%), rectal (n=3, 4%), prostate (n=1, 1%), and other (n=24, 34%). Catheter survival was 58.6% (95% CI 46.9 to 69.4) at 12 weeks and no catheters were removed due to thrombosis. Patients had their CVCs removed prior to the end of the study due to end of therapeutic need (n=20), infection (n=2), bleeding (n=2), kinking (n=2), patient preference (n=2), and death (n=1). The 3-month incidence rate of recurrent VTE was 1.43% (95% CI 0.25 to 7.66). There was 1 episode of recurrent VTE presenting as a fatal PE at 6 weeks. It was not known if the patient had a concurrent leg DVT at the time of the PE. There were no other deaths from any cause during the study. There were 11 bleeding events in 9 patients (12.85%, 95%CI 6.9 to 22.7), 6 major and 5 CRNMB (Figure 1). All bleeding events happened during the first 39 days of treatment. 7 patients discontinued anticoagulation during the study due to death (n=1), patient or clinician preference (n=5) and dermatological adverse reaction (n=1). Discussion In this study rivaroxaban showed promise in treating CVC-associated UEDVT in cancer patients, resulting in preserved CVC function. However, the bleeding rates and the occurrence of 1 death due to pulmonary embolism is concerning since we cannot exclude a causative role for the known UEDVT. Further studies are still required prior to recommending rivaroxaban in this setting. Figure 1 Kaplan-Meier curve for cumulative bleeding risk. Figure 1.

Abstract Background: XALIA is a prospective, non-interventional study of rivaroxaban in the treatment of acute deep vein thrombosis. The overall XALIA results showed that rivaroxaban was associated with similarly low rates of major bleeding and symptomatic recurrent venous thromboembolism (VTE) as standard anticoagulation. A subset of patients in XALIA had active cancer at the time of enrolment into the study. Purpose: To describe the demographics, clinical characteristics, treatment strategies and outcomes of patients in XALIA with cancer and VTE. The primary outcomes were major bleeding, recurrent VTE and all-cause mortality. Methods: Patients with deep vein thrombosis with or without concomitant pulmonary embolism aged ≥18 years who had active cancer and were scheduled to receive ≥3 months of anticoagulation with rivaroxaban or standard therapy were eligible. Therapy type, dose and duration were at the physician's discretion. For the purpose of this substudy, we defined the following treatment cohorts: rivaroxaban cohort (patients treated with rivaroxaban alone or who received heparin/fondaparinux for ≤48 hours before switching to rivaroxaban); early switchers cohort (patients treated with rivaroxaban who received heparin/fondaparinux for >48 hours-14 days and/or a vitamin K antagonist [VKA] for 1-14 days before changing to rivaroxaban); standard anticoagulation cohort (patients treated with heparin/fondaparinux and a VKA or a VKA only); and heparin/fondaparinux cohort (patients treated with heparin/fondaparinux alone). Results: Of 5136 patients in XALIA who received study medication, 587 (11.4%) had active cancer at baseline. Of these, 146 (24.9%) received rivaroxaban, 30 (5.1%) were early switchers, 167 (28.4%) received standard anticoagulation (of which 26 [4.4%] received a VKA only) and 244 (41.6%) received heparin/fondaparinux only, of whom 223 (38.0%) received low molecular weight heparin and the remainder other heparins or fondaparinux. Demographics are shown in Table 1. The most common type of active cancer at baseline in all cohorts was genitourinary, with the exception of the heparin/fondaparinux cohort where gastrointestinal cancer was the most common type (Table 2). The incidence rates for the primary outcomes for each cohort are shown in Figure 1. The rates of major bleeding were highest in the standard anticoagulation cohort (n=8 [4.8%]) and lowest in the early switchers (no major bleeding events occurred). The rates of recurrent VTE were similar in the in the rivaroxaban, early switcher and standard anticoagulation cohorts (n=5 [3.4%], n=1 [3.3%] and n=6 [3.6%], respectively) and were highest in the heparin/fondaparinux cohort (n=12 [4.9%]). All-cause mortality was highest in the heparin/fondaparinux cohort (n=61 [25.0%]) and lowest in the early switchers (no deaths occurred). Conclusions: In the real-world XALIA study, 38.0% of patients with cancer received treatment with low molecular weight heparin, which was in line with guidelines. The remaining patients received rivaroxaban, standard anticoagulation or were early switchers. For the three primary outcomes, the lowest incidence rates were observed in the early switcher cohort. The highest rates were in the standard anticoagulation cohort for major bleeding and the heparin/fondaparinux cohort for recurrent VTE and all-cause mortality; rates for all three primary outcomes were low in the rivaroxaban cohort, suggesting that rivaroxaban may be a safe and effective treatment option for patients with VTE and active cancer.

Abstract Introduction. Upper extremity deep vein thrombosis (UEDVT) is a relatively uncommon event with potentially serious complications. Its clinical outcomes are not well studied. The objective of this study was to assess the incidence of post-thrombotic syndrome (PTS) and functional disability in patients with UEDVT. Patients and methods. This was a pre-specified analysis of a prospective cohort study at 5 Canadian centres. We enrolled adult patients with a symptomatic UEDVT confirmed by compression ultrasound involving the brachial or more proximal veins, with or without a pulmonary embolism (PE). Exclusions included pregnancy, dialysis catheter thrombosis, active or high bleeding risk, platelet count <100x109/L, creatinine clearance < 30 ml/min, on warfarin for other indications, hemodynamically unstable PE, acute leukemia or undergoing a stem cell transplant within 3 months, geographical inaccessibility, life expectancy <3 months or treatment with low molecular weight heparin (LMWH) or warfarin for more than 7 days since diagnosis. Standardized treatment regimens were used as follows: spontaneous or central venous catheter (CVC)-related UEDVT were treated with dalteparin at therapeutic doses for at least 5 days followed by warfarin adjusted according to INR results. Spontaneous UEDVT was treated for at least 6 months and CVC-related events were treated for at least 3 months or for as long as the line remained in place and for at least 1 month after line removal. Cancer patients with non CVC-related UEDVT were treated using dalteparin alone for a minimum of 6 months. Outcomes were assessed at 12, 18 and 24 months and included the occurrence of PTS evaluated using a modified Villalta Score. PTS was defined for patients with a score of 5 or greater and severe PTS was defined by a score of 15 or higher. Functional disability was evaluated using the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire. Patients were followed for 2 years. Data was analyzed using descriptive statistics. Confidence intervals for proportions were estimated using the Wilson's score method. Groups were compared using χ2 and Student's t- tests, as appropriate. The study was approved by all institutional review boards. Results. Between 2009 and 2012, we enrolled 141 patients: 75 with spontaneous and 66 with CVC related UEDVT. Mean age was 51 years and 55% were males. There were 78, 59 and 56 patients with evaluable data at 12, 18 and 24 months, respectively. The percentage of patients with ipsilateral PTS is shown in Table 1. There was no difference between patients with spontaneous or CVC- related UEDVT. Functional disability scores are shown in Table 2. Overall, patients developing PTS had higher functional disability at all time points, compared to patients without PTS. Conclusion. In this prospective cohort study PTS occurred in approximately one fifth of patients after UEDVT and was associated with more functional disability, although the majority of cases were mild according to the modified Villata score. No differences were observed between CVC-related and spontaneous UEDVT. Disclosures Lazo-Langner: Bayer: Honoraria; Pfizer: Honoraria; Daiichi Sankyo: Research Funding.

Abstract Introduction: Anticoagulation plays a crucial role in the treatment of splanchnic vein thrombosis (SVT), including thrombosis of the portal (PVT), mesenteric (MVT) and splenic (SpVT) veins. Rivaroxaban is a potential alternative to heparins and vitamin K antagonists (VKA) in these patients, but data to support its use are scant. Several recent guidelines highlighted the limited evidence available for the use of the direct oral anticoagulants in these patients. In addition, despite anticoagulation, SVT patients carry high risk of recurrent venous thromboembolic events. The aim of this study was to evaluate the safety and efficacy of rivaroxaban for the acute-phase treatment of SVT (first 3 months of treatment). Methods: RIVASVT-100 (NCT02627053) was a prospective cohort study of adult patients with a first episode of symptomatic, objectively diagnosed PVT, MVT or SpVT. Exclusion criteria were known liver cirrhosis, Budd-Chiari syndrome, previous or ongoing variceal bleeding, portal cavernoma, thrombocytopenia, severe renal failure, life expectancy &lt;3 months, concomitant interfering medications, treatment with therapeutic dose of heparins for &gt;7 days, ongoing VKA treatment. Patients received rivaroxaban 15 mg twice daily for 3 weeks, followed by 20 mg once daily for a total of 3 months. Afterwards, the decision to continue any available anticoagulant drug was left to the discretion of the attending physicians. Follow-up was performed at 3 weeks, 2 months, 3 months and 6 months. Primary outcome was the occurrence of ISTH-defined major bleeding events during the 3 months of active treatment and up to 2 days after the end of study treatment. Secondary outcomes included death, clinically relevant non-major bleeding (CRNMB), recurrent SVT or symptomatic venous thromboembolism in other sites. We here report the results of the 3-month follow-up. Results: Between June 2015 and March 2021, 103 patients were enrolled from 18 participating centres. After excluding 3 patients who did not meet the criteria for eligibility, 100 patients were included in the analysis. Mean (SD) age was 54.4 (± 15.5) years; 64% were males. Overall, 74% of patients had PVT, 61% MVT and 48% SpVT; 53% of SVT occurred in multiple sites. The most common risk factors were abdominal inflammation/infection (26%), followed by solid cancer (9%), overt myeloproliferative neoplasms (9%) and oestrogen hormonal therapy (9%), while 43% of cases were unprovoked. The JAK2 V617F mutation was detected in 13 out of 50 tested patients (26%). Rivaroxaban was the sole anticoagulant agent used in 21% of patients, whereas the remaining received a combination of anticoagulants, which included low molecular weight heparin, unfractionated heparin or fondaparinux for a median of 5.0 days before transitioning to rivaroxaban. Three patients were lost to follow-up but known to be alive at the end of the study. At 3-month follow-up, 1 (1.0%) patient died due to a non-SVT related cause. Two patients (2.06%; 95% CI, 0.57-7.21) had major bleeding events (both gastrointestinal), while 3 patients (3.09%) had CRNMB. There were 2 recurrent SVT (2.06%) during rivaroxaban treatment, one of these occurred in a patient with metastatic solid cancer. The 6-month follow-up for the last enrolled patient is ongoing. Conclusions: Rivaroxaban appears to be safe and effective for the acute-phase treatment of SVT in non-cirrhotic patients.

SummaryWhether atrial fibrillation (AF) is associated with an increased risk of venous thromboembolism (VTE) remains controversial. From Longitudinal Health Insurance Database 2000 (LHID2000), we identified 11,458 patients newly diagnosed with AF. The comparison group comprised 45,637 patients without AF. Both cohorts were followed up to measure the incidence of deep-vein thrombosis (DVT) and pulmonary embolism (PE). Univariable and multivariable competing-risks regression model and Kaplan-Meier analyses with the use of Aelon-Johansen estimator were used to measure the differences of cumulative incidences of DVT and PE, respectively. The overall incidence rates (per 1,000 person-years) of DVT and PE between the AF group and non-AF groups were 2.69 vs 1.12 (crude hazard ratio [HR] = 1.92; 95 % confidence interval [CI] = 1.54-2.39), 1.55 vs 0.46 (crude HR = 2.68; 95 % CI = 1.97-3.64), respectively. The baseline demographics indicated that the members of the AF group demonstrated a significantly older age and higher proportions of comorbidities than non-AF group. After adjusting for age, sex, and comorbidities, the risks of DVT and PE remained significantly elevated in the AF group compared with the non-AF group (adjusted HR = 1.74; 95 %CI = 1.36-2.24, adjusted HR = 2.18; 95 %CI = 1.51-3.15, respectively). The Kaplan-Meier curve with the use of Aelon-Johansen estimator indicated that the cumulative incidences of DVT and PE were both more significantly elevated in the AF group than in the non-AF group after a long-term follow-up period (p<0.01). In conclusion, the presence of AF is associated with increased risk of VTE after a long-term follow-up period.

SummaryThe established initial treatment of patients with deep vein thrombosis (DVT) or pulmonary embolism (PE) consists of the administration of subcutaneous, weight adjusted, low-molecular weight heparin (LMWH). However, the use of the same LMWH dosages for patients with either DVT or PE is not supported by data from comparative studies.1,000 consecutive patients with acute, proximal DVT were prospectively evaluated. All patients underwent a ventilation-perfusion lung scan on admission, and remained in hospital for at least 7 days. Patients with silent PE received once daily 10,000 to 15,000 IU subcutaneous LMWH dalteparin according to body weight for 7 days, and then vitamin K antagonists. Patients with DVT alone received LMWH in a fixed dose of 10,000 IU once daily for at least 5 days, and then vitamin K antagonists. The rate of both, major bleeding and symptomatic PE episodes during the 7-day study period was evaluated.Thirteen patients (1.3%) developed recurrent PE (1 died) and 16 patients (1.6%) had major bleeding (7 died). Recurrent PE was significantly more common in patients with silent PE (9 of 258 patients, 3.5%) than in those with DVT alone (4 of 742 patients, 0.5%. Odds ratio: 6.5; p <0.001). There were no significant differences in bleeding rate between patients with silent PE and those with DVT alone. However, the use of a fixed 10,000 IU dose in patients with DVT alone led to a significantly lower bleeding rate in patients weighing over 70 kg: 1 of 349 patients (0.3%) as compared to 9 of 393 patients (2.3%) in those weighing less than 70 kg (odds ratio: 0.12; p = 0.018).Fixed-dose 10,000 IU of LMWH dalteparin once daily proved to be both effective and safe in patients with DVT alone. The observed recurrence rate of 0.5% in these patients compares favourably with the 3.5% rate in patients with silent PE. Furthermore, this fixed-dosage was also safe. Patients weighing over 70 kg had a significant decrease in the rate of major bleeding, and no compensatory increase in the rate of recurrent PE.

SummaryCancer patients with acute venous thromboembolism (VTE) have an increased incidence of recurrences and bleeding complications while on anticoagulant therapy. Methods RIETE is an ongoing registry of consecutive patients with acute VTE. We tried to identify which cancer patients are at a higher risk for recurrent pulmonary embolism (PE), deep vein thrombosis (DVT) or major bleeding. Up to May 2007, 3, 805 cancer patients had been enrolled in RIETE. During the first three months of follow-up after the acute, index VTE event, 90 (2.4%) patients developed recurrent PE, 100 (2.6%) recurrent DVT, 156 (4.1%) had major bleeding. Forty patients (44%) died of the recurrent PE,46 (29%) of bleeding. On multivariate analysis, patients aged <65 years (odds ratio [OR]: 3.0; 95% confidence interval [CI]: 1.9–4.9), with PE at entry (OR: 1.9; 95% CI: 1.2–3.1), or with <3 months from cancer diagnosis to VTE (OR: 2.0; 95% CI: 1.2–3.2) had an increased incidence of recurrent PE. Those aged <65 years (OR: 1.6; 95% CI: 1.0–2.4) or with <3 months from cancer diagnosis (OR: 2.4; 95% CI: 1.5–3.6) had an increased incidence of recurrent DVT. Finally, patients with immobility (OR: 1.8; 95% CI: 1.2–2.7), metastases (OR: 1.6; 95% CI: 1.1–2.3), recent bleeding (OR: 2.4; 95% CI: 1.1–5.1), or with creatinine clearance <30 ml/ min (OR: 2.2; 95% CI: 1.5–3.4), had an increased incidence of major bleeding. With some variables available at entry we may identify those cancer patients withVTE at a higher risk for recurrences or major bleeding.
