Histopathological Features of Cancer-Associated Venous Thromboembolism: Presence of Intrathrombus Cancer Cells and Prothrombotic Factors.

ABSTRACT:

Background

Cancer-associated venous thromboembolism (VTE) is a critical complication in patients with cancer. However, the pathological findings of VTE are limited. Here, we investigated the histopathological features of cancer-associated VTE in human autopsy cases.

Methods

We clinically examined the autopsy cases of VTE with (n=114) and without cancer (n=66) and immunohistochemically analyzed the expression of prothrombotic factors in intrathrombus cancer cells, the thrombus contents of erythrocytes, fibrin, platelets, citrullinated histone H3, and degree of organization.

Results

Vascular wall invasion or small cell clusters of cancer cells was observed in thrombi in 27.5% of deep vein thrombosis and 25.9% of pulmonary embolism cases. The majority of the cancer cells in deep vein thrombi appeared to be invading the vessel wall, whereas the majority of pulmonary thrombi had cancer cell clusters, consistent with embolization via blood flow. These cancer cells were immunohistochemically positive for TF (tissue factors) or podoplanin in up to 88% of VTE cases. The frequency of TF-positive monocyte/macrophages in thrombi was higher in cancer-associated VTE than that in VTE without cancer. Citrullinated histone H3 was predominantly observed in the early stages of organizing thrombi. There was no significant difference in thrombus components between VTE with cancer and without cancer groups.

Conclusions

Vascular wall invasion or cancer cell clusters in thrombi might influence thrombogenesis of cancer-associated VTE. TF and podoplanin in cancer cells and in monocyte/macrophages may induce coagulation reactions and platelet aggregation. Neutrophil extracellular traps may play a role in the early stages of VTE, regardless of cancer status.

Project description:ImportanceIt is uncertain to what extent established cardiovascular risk factors are associated with venous thromboembolism (VTE).ObjectiveTo estimate the associations of major cardiovascular risk factors with VTE, ie, deep vein thrombosis and pulmonary embolism.Design, setting, and participantsThis study included individual participant data mostly from essentially population-based cohort studies from the Emerging Risk Factors Collaboration (ERFC; 731 728 participants; 75 cohorts; years of baseline surveys, February 1960 to June 2008; latest date of follow-up, December 2015) and the UK Biobank (421 537 participants; years of baseline surveys, March 2006 to September 2010; latest date of follow-up, February 2016). Participants without cardiovascular disease at baseline were included. Data were analyzed from June 2017 to September 2018.ExposuresA panel of several established cardiovascular risk factors.Main outcomes and measuresHazard ratios (HRs) per 1-SD higher usual risk factor levels (or presence/absence). Incident fatal outcomes in ERFC (VTE, 1041; coronary heart disease [CHD], 25 131) and incident fatal/nonfatal outcomes in UK Biobank (VTE, 2321; CHD, 3385). Hazard ratios were adjusted for age, sex, smoking status, diabetes, and body mass index (BMI).ResultsOf the 731 728 participants from the ERFC, 403 396 (55.1%) were female, and the mean (SD) age at the time of the survey was 51.9 (9.0) years; of the 421 537 participants from the UK Biobank, 233 699 (55.4%) were female, and the mean (SD) age at the time of the survey was 56.4 (8.1) years. Risk factors for VTE included older age (ERFC: HR per decade, 2.67; 95% CI, 2.45-2.91; UK Biobank: HR, 1.81; 95% CI, 1.71-1.92), current smoking (ERFC: HR, 1.38; 95% CI, 1.20-1.58; UK Biobank: HR, 1.23; 95% CI, 1.08-1.40), and BMI (ERFC: HR per 1-SD higher BMI, 1.43; 95% CI, 1.35-1.50; UK Biobank: HR, 1.37; 95% CI, 1.32-1.41). For these factors, there were similar HRs for pulmonary embolism and deep vein thrombosis in UK Biobank (except adiposity was more strongly associated with pulmonary embolism) and similar HRs for unprovoked vs provoked VTE. Apart from adiposity, these risk factors were less strongly associated with VTE than CHD. There were inconsistent associations of VTEs with diabetes and blood pressure across ERFC and UK Biobank, and there was limited ability to study lipid and inflammation markers.Conclusions and relevanceOlder age, smoking, and adiposity were consistently associated with higher VTE risk.

Project description:ImportanceThe size of the risk of recurrent venous thromboembolism (VTE) after surgery in patients with a history of VTE is not well known.ObjectivesTo estimate the risk of and to identify the factors associated with recurrent VTE in patients undergoing surgery who have a history of VTE.Design, setting, and participantsThis population-based, follow-up cohort study includes patients with VTE who participated in the Multiple Environment and Genetic Assessment (MEGA) study. Original data were collected from March 1999 to April 2010. Data analysis began in June 1999 and ended in April 2010.ExposuresSurgery following a first VTE.Main outcomes and measurementsKaplan-Meier analyses were used to estimate cumulative incidences of recurrent VTE. Cox regression with a time-dependent covariate (surgery) was used to calculate the hazard ratio (HR) for developing recurrent VTE after surgery compared with no surgery.ResultsOverall, 3741 patients (mean [SD] age, 48.4 [12.8] years; 2020 [54.0%] women) with a history of VTE were included in the analysis, amounting to 18 899 person-years, with a median (interquartile range) follow-up of 5.7 (3.0-7.2) years. Of the 3741 patients, 580 (15.5%) underwent surgery and 601 (16.1%) developed a recurrent thrombotic event. The 1-month cumulative incidence of recurrent VTE for all surgery types was 2.1% (95% CI, 1.2%-3.6%), which increased to 3.3% (95% CI, 2.1%-5.1%) at 3 months and 4.6% (95% CI, 3.1%-6.6%) at 6 months. At 6 months, risk of recurrent VTE ranged from 2.3% to 9.3%, depending on surgery type. In addition to surgery type, factor V Leiden mutation (HR, 3.4; 95% CI, 1.6-7.4) and male sex (HR, 2.7; 95% CI, 1.3-5.8) were associated with increased risk of recurrent VTE.Conclusions and relevanceSurgery was associated with an increased risk of recurrent VTE in patients with a history of VTE; risk remained high for up to 6 months after the procedure. This study suggests that high-risk individuals may be identified based on surgery type, sex, and the presence of factor V Leiden mutation. These findings stress the need for revision of the current thromboprophylactic approach to prevent recurrence in these patients.

Project description:Tuberculosis (TB) patients who develop venous thromboembolism (VTE) have poor clinical outcomes. This study aimed to explore the risk factors and the prognosis of TB patients with VTE. A total of 11 267 with TB patients from the Zhejiang University-affiliated Chest Hospital, China, were enrolled between January 2016 and January 2020. A total of 107 TB patients with VTE were selected as the VTE group. Patients in the control group were randomly screened in a 1:1 ratio between the VTE and control groups. Univariate and multivariate logistic regression analysis was used to evaluate the factors associated with VTE in TB patients. Of the 214 patients, 145 (60.17%) were male, 69 (32.2%) were female, with an average age of 62.21 ± 19.35. The incidence of VTE in TB patients was 0.95%. Using a univariate analysis, it was found that age, fever, dyspnea, lower limb edema, respiratory failure, malignant tumor, prothrombin time, activated partial thromboplastin time, D-dimer, and hemoglobin levels were different between the two groups (P < 0.05). Multivariate logistic regression analysis showed that higher D-dimer value, higher incidence of lower limb edema, and TB were risk factors for VTE; OR (95%CI) = 8.840 (2.383-32.794); OR (95%CI) = 4.957 (1.219-20.161); OR (95%CI) = 16.216 (4.779-55.025). However, the use of Rifamycin was found to be a protective factor against VTE [OR (95%CI) = 0.170(0.073-0.395)]. Receiver operating characteristic curve (ROC) curve of D-dimer (area under curve [AUC] = 0.831 ± 0.028 [95%CI: 0.776-0.886, P < 0.05]) and the cut-off value of 1855 μg/L was obtained according to the Youden index, with a sensitivity and a specificity rate of 82.2% and 74.3%, respectively. The risks of VTE seem higher in TB patients with fever, dyspnea, lower limb edema, and D-dimer levels of more than 1855 μg/L; therefore, it should be actively screened, and prophylactic anticoagulation given if necessary. Effective directly observed treatment plus short-course chemotherapy (DOTS) protocol anti-TB therapy helps reduce the probability of VTE in TB patients.
