304 Background: Venous thromboembolism (VTE) is a common cause of morbidity and mortality in cancer patients. Because biliary tract cancers (BTC) cholangiocarcinoma and gallbladder (GB) cancer are uncommon, the incidence of VTE in this population are not well-described. Methods: We conducted a retrospective study of patients with BTC identified by the cancer registry at the Los Angeles County-University of Southern California (USC) Medical Center, USC Norris Cancer Center, and USC Keck Hospital between January 2011 to December 2016 to describe the incidence of VTE. 330 BTC patients’ medical records were reviewed for demographics, tumor characteristics, treatment history, and VTE events. 41 patients were excluded due to incomplete records/follow-up. Overall survival (OS) was calculated from date of diagnosis to date of death or last follow-up. Logrank test was used to evaluate the association of VTE with OS. Results: 289 patients with BTC were identified (177 cholangiocarcinoma, 112 GB) with a median follow-up period of 16.7 (0.3-89.0) months (mo). 169 (58%) were women. The median age at diagnosis of 66 years (range 22-89). 144 (59%) underwent cancer surgery and 274 (95%) received chemotherapy. 65 (22%) patients had VTE events: 22 pulmonary embolism [PE] with or without lower extremity (LE) deep vein thrombosis [DVT], 15 with LE DVT alone, three with upper extremity DVT, and 30 with visceral thrombosis (27 portal vein thrombosis [PVT] with or without inferior vena cava thrombosis [IVC], 2 IVC thrombosis, two hepatic vein thrombosis). Five patients had both DVT/PE and visceral thrombosis. The median time from cancer diagnosis to VTE event was not met. Patients with a PVT or any visceral thrombosis had an inferior OS compared to those without (PVT: median OS 16.2 mo [95% CI 12.2-25.8] versus 7.5 [3.4-14.2], p = 0.10, visceral thrombosis: 17.0 mo [95% CI 11.8-25.9] versus 8.4 [95% CI 3.7-14.3], p = 0.30). There was a non-significant trend towards inferior OS in patients with any VTE event type (median OS 17.0 mo [95% CI 11.8-39.0] versus 11.4 [95% CI 7.2-18.4], p = 0.10). There was no difference in OS for patients with PE/DVT compared to those without. Conclusions: VTE is commonly observed in patients with BTC. Visceral thrombosis is associated with inferior survival in patients with BTC.

e19645 Background: The natural history of isolated gonadal vein thrombosis (GVT) occurring in cancer patients (pts) is not well described in the medical literature. GVT in cancer pts it is of uncertain clinical significance. Methods: Utilizing a software program allowing a searchable database of radiology reports, the computerized tomographic scan (CT) reports of pts at a single cancer center from January 1, 2004 to June 30, 2011, were searched for the term “gonadal vein thrombus”. Pts included in this analysis had a diagnosis of cancer, isolated GVT (i.e. no evidence of thrombosis at another site), and at least six months of follow-up information. Results: 162 cancer pts with GVT were identified for analysis [median age 57.8 ± 12 years, right GVT 89 pts (54.9%), left GVT 59 pts (36.4%), bilateral 14 pts (8.6%)]; the majority of the pts (96, 59.3%) had a non-gynecologic malignancy. At the time of diagnosis of GVT the majority of pts were receiving chemotherapy (84, 51.9%); 70 pts (43.2%) had surgery within the prior six months (the most common being hysterectomy, 127 pts, 78.6%). The majority of pts in this study had metastatic disease (93, 57.4%) as well as active cancer (138, 85.1%, defined as GVT occurring at the time of cancer diagnosis, disease recurrence, metastatic disease, or treatment for cancer within the prior six months); median follow-up time was 22 months. A minority of pts received anticoagulation (28pts, 17.2%). Twenty-two pts (13.6%) developed a recurrent venous thromboembolic event (VTE); these events were pulmonary embolism (12 pts, 7.4%), deep venous thrombosis (5 pts, 3.1%), inferior vena cava thrombosis (4 pts, 2.5%). Median time to development of re-thrombosis was 7 months (range 2-13.5 months). Active cancer was the only risk factor significantly associated with recurrent VTE (p = 0.047); pts with prior hysterectomy had a significantly reduced risk of recurrent VTE (p = 0.036). Conclusions: Incidental isolated GVT identified in cancer pts has a high risk of recurrent VTE (13.6%). Based upon specific pts risk factors for VTE, treatment of an incidentally detected GVT in cancer pts with anticoagulation, as per guidelines for other VTE sites, may be indicated.

e15087 Background: Venous thromboembolism (VTE) in patients with gastrointestinal (GI) and non‐small cell lung cancer (NSCLC) is common and increases morbidity and mortality. In advanced GI and NSCLC, molecular subtyping has increased use of next-generation sequencing (NGS). The association between tumor mutation profile and VTE risk remains undetermined. Methods: We conducted a retrospective cohort study of consecutive GI/NSCLC patients from 2014-2019 with NGS and follow‐up at Brown Cancer Center. The NGS platform detected substitutions, indels, copy number alterations and select rearrangements in 324 genes. Patients with thrombophilia, anticoagulation use or >1 malignancy were excluded. VTE was defined as deep vein thrombosis, pulmonary embolism or visceral vein thrombosis within 6 months prior to diagnosis or any time after. For statistical analysis SAS 9.5 was used with significance at alpha=0.05. Multinomial logistic regression was performed, in which the log odds of VTE was modeled as a linear combination of the genes. Odds ratios and 95% confidence intervals for VTE were generated. Results: A total of 364 patients were reviewed; after exclusions 326 patients were included comprising Stage III/IV NSCLC (58%), metastatic colorectal (33%) and other metastatic GI cancers - gastric, duodenal, esophageal, pancreatic and cholangiocarcinoma (9%). Approximately half (53%) were males with mean age of 59.1 yrs and 76.4% current/former smokers. There was a low level of microsatellite instability (0.9%). VTE occurred in 75 patients (23%) during a mean follow‐up of 24.5 months. Only 1 patient had surgery within 90 days prior to VTE. Of 248 genes mutated in the VTE group, 9 were more prevalent compared to those without VTE (Table). Statistical analysis showed PIK3CA, PTCH1, FGF6, and NRAS mutations significantly increased odds of VTE, with PIK3CA the most prevalent of these (Table). Conclusions: Patients with PIK3CA, PTCH1, FGF6 and NRAS mutations had significantly higher VTE risk. These tumor mutations and associated pathways may provide novel insight into risk stratification, prevention and targeted treatment of VTE in cancer. [Table: see text]

Ovarian Vein Thrombosis

SummaryFor patients with ovarian vein thrombosis (OVT), neither the rate of recurrence nor the expected survival are well established. Clarification of these natural history data would aid in defining the optimal management. We studied all female patients with OVT seen at the Mayo Clinic between 1990 and 2006. Survival, recurrent venous thrombosis rates, and prothrombotic factors were compared to a randomly selected group of 114 female patients with lower extremity venous thrombosis (DVT). Patients with OVT (n=35; mean age 44.8 ± 17.9 years) were significantly more likely to be under hormonal stimulation (48%), have an underlying malignancy (34%), experienced recent pelvic infection (23%) or undergone recent surgery (20%), compared to DVT patients. Duringa mean follow-up period of 34.6 ± 44.3 months, three patients suffered three recurrent venous thrombi (event rate: three per 100 patient years of follow-up).This recurrence rate was comparable to patients with lower extremity DVT (2.2 per 100 patient years). Recurrent thrombosis involved the contralateral ovarian vein, left renal vein, and inferior vena cava. The five-year mortality rate for OVT patients was 43% compared to 20% for DVT patients (p=0.08). All OVT deaths were cancer related. Survival was greater in OVT patients without cancer compared to those with active cancer (p<0.0001). In conclusion, venous thromboembolism recurrence rates are low and comparable to lower extremity DVT. Therefore general treatment guidelines for lower extremity DVT may be applicable. Poor survival rates in OVT are principally governed by the presence of malignancy.

SummaryA high incidence of post-discharge venous thromboembolism in orthopaedic surgery patients has been recently reported drawing further attention to the unresolved issue of the optimal duration of the pharmacological prophylaxis. We performed an overview analysis in order to evaluate the incidence of late occurring clinically overt venous thromboembolism in major orthopaedic surgery patients discharged from the hospital with a negative venography and without further pharmacological prophylaxis. We selected the studies published from January 1974 to December 1995 on the prophylaxis of venous thromboembolism after major orthopaedic surgery fulfilling the following criteria: 1) adoption of pharmacological prophylaxis, 2) performing of a bilateral venography before discharge, 3) interruption of pharmacological prophylaxis at discharge in patients with negative venography, and 4) post-discharge follow-up of the patients for at least four weeks. Out of 31 identified studies, 13 fulfilled the overview criteria. The total number of evaluated patients was 4120. An adequate venography was obtained in 3469 patients (84.1%). In the 2361 patients with negative venography (68.1%), 30 episodes of symptomatic venous thromboembolism after hospital discharge were reported with a resulting cumulative incidence of 1.27% (95% C.I. 0.82-1.72) and a weighted mean incidence of 1.52% (95% C.I. 1.05-1.95). Six cases of pulmonary embolism were reported. Our overview showed a low incidence of clinically overt venous thromboembolism at follow-up in major orthopaedic surgery patients discharged with negative venography. Extending pharmacological prophylaxis in these patients does not appear to be justified. Venous thrombi leading to hospital re-admission are likely to be present but asymptomatic at the time of discharge. Future research should be directed toward improving the accuracy of non invasive diagnostic methods in order to replace venography in the screening of asymptomatic post-operative deep vein thrombosis.

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.

SummaryIn some patients with previous venous thromboembolism (VTE) D-dimer levels (D-Dimer) tend to increase after oral anticoagulant therapy (OAT) is stopped. The aim of our study was to evaluate the predictive value of D-Dimer for the risk of VTE recurrence after OAT withdrawal. After a first episode of deep vein thrombosis (DVT) of the lower limbs and/or pulmonary embolism (PE), 396 patients (median age 67 years, 198 males) were followed from the day of OAT discontinuation for 21 months. D-dimer was measured on the day of OAT withdrawal (T1), 3-4 weeks (T2) and 3 months (+/− 10 days, T3) thereafter. The main outcome events of the study were: objectively documented recurrent DVT and/or PE. D-dimer was found to be increased in 15.5%, 40.3% and 46.2% of the patients at T1, T2 and T3, respectively. In 199 (50.2%) patients, D-dimer levels were elevated in at least one measurement. During a follow-up of 628.4 years, 40 recurrences were recorded (10.1% of patients; 6.4% patient-years of follow-up). D-dimer was increased in at least one measurement in 28 of these cases, but remained normal in 11 subjects (three of whom had recurrent events triggered by circumstantial factors, three with malignancyassociated factors) (in one subject D-dimer was not measured). The negative predictive value (NPV) of D-dimer was 95.6% (95% CI 91.6-98.1) at T3 and was even higher (96.7%; 95% CI 92.9-98.8) after exclusion of the six recurrences due to circumstantial factors. Only five idiopathic recurrences occurred in the 186 patients with consistently normal D-dimer. In conclusion, D-dimer has a high NPV for VTE recurrence when performed after OAT discontinuation.

ObjectiveTo compare the characteristics/management of acute venous thromboembolism (VTE) for patients either discharged directly from the emergency department (ED) or hospitalised throughout a year within two urban cities in Canada.DesignRetrospective medical record review.SettingHospitals in Edmonton, Alberta (n=4) and Regina, Saskatchewan (n=2) from April 2014 to March 2015.ParticipantsAll patients discharged from the ED or hospital with acute deep vein thrombosis or pulmonary embolism (PE). Those having another indication for anticoagulant therapy, pregnant/breast feeding or anticipated lifespan <3 months were excluded.Primary and secondary outcomesPrimarily, to compare proportion of patients receiving traditional therapy (parenteral anticoagulant±warfarin) relative to a direct oral anticoagulant (DOAC) between the two cohorts. Secondarily, to assess differences with therapy selected based on clot burden and follow-up plans postdischarge.Results387 (25.2%) and 665 (72.5%) patients from the ED and hospital cohorts, respectively, were included. Compared with the ED cohort, those hospitalised were older (57.3 and 64.5 years; p<0.0001), more likely to have PE (35.7% vs 83.8%) with a simplified Pulmonary Embolism Severity Index (sPESI) ≥1 (31.2% vs 65.2%), cancer (14.7% and 22.3%; p=0.003) and pulmonary disease (10.1% and 20.6%; p<0.0001). For the ED and hospital cohorts, similar proportions of patients were prescribed traditional therapies (72.6% and 71.1%) and a DOAC (25.8% and 27.4%, respectively). For the ED cohort, DOAC use was similar between those with a sPESI score of 0 and ≥1 (35.1% and 34.9%, p=0.98) whereas for those hospitalised lower risk patients were more likely to receive a DOAC (31.4% and 23.8%, p<0.055). Follow-up was most common with family physicians for those hospitalised (51.5%), while specialists/VTE clinic was most common for those directly discharged from the ED (50.6%).ConclusionsTraditional and DOAC therapies were proportionately similar between the ED and hospitalised cohorts, despite clear differences in patient populations and follow-up patterns in the community.

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.

Abstract Objective We retrospectively analyzed the incidence and localization of venous thromboembolism in patients undergoing chemotherapy for advanced germ cell tumor and separately evaluated the risk factors for venous thromboembolism development before and during chemotherapy. Methods We included 121 patients treated with cisplatin-based chemotherapy between 2005 and 2018. Venous thromboembolism was defined as venous thrombosis diagnosed using radiological imaging with or without thromboembolic symptoms. We analyzed the clinical parameters for identifying the possible venous thromboembolism risk factors. Khorana score was used to calculate the venous thromboembolism risk. Results Thirteen patients showed prechemotherapy venous thromboembolism and 13 developed venous thromboembolism during chemotherapy. The most common venous thromboembolism was deep vein thrombosis (10 patients), followed by inferior vena cava thrombus (eight patients) and pulmonary thrombus (six patients). Compared to the group without venous thromboembolism, the group with prechemotherapy venous thromboembolism showed higher proportion of patients with tumors originating in the right testis (10 out of 13), significantly higher lactate dehydrogenase levels (828 IU/L versus 436 IU/L, P = 0.013), significantly higher proportion of patients with retroperitoneal lymph node (RPLN) metastases &gt;5 cm in diameter (76.9% versus 33.7%, P = 0.003) and slightly higher proportion of patients with high-risk Khorana score (≥ 3; 30.8% versus 11.6%). No significant differences were observed between the clinical characteristics of patients with venous thromboembolism developed during chemotherapy and patients without venous thromboembolism. Conclusions We show that both RPLN mass &gt; 5 cm and high lactate dehydrogenase levels are significant risk factors for prechemotherapy venous thromboembolism but not for venous thromboembolism development during chemotherapy.
