ABSTRACT

BACKGROUND: Isolated distal deep vein thrombosis (IDDVT) is a common clinical presentation of DVT. The efficacy and safety of anticoagulant therapy for the management of IDDVT in patients with cancer are unclear. We sought to assess the incidence of recurrent venous thromboembolism (VTE) and major bleeding in this patient population.

METHODS: A systematic search of MEDLINE, EMBASE and PubMed, from inception to June 2, 2022 was performed. The primary efficacy outcome was recurrent VTE and the primary safety outcome was major bleeding. The secondary outcomes were clinically relevant non-major bleeding (CRNMB) and mortality. The incidence rates of thrombotic, bleeding, and mortality outcomes were pooled using random effects model and expressed as events per 100 patient-months with associated 95 % confidence intervals (CI).

RESULTS: Out of a total of 5234 articles, 10 observational studies including 8160 patients with cancer and IDDVT were included in the analysis. The incidence rate of recurrent VTE was 5.65 (95 % CI: 2.09-15.30) per 100 patient-years regardless of type and duration of anticoagulant therapy. The incidence rate of major bleeding was 4.08 (95 % CI: 2.52-6.61) per 100 patient-years. The incidence rates for CRNMB and mortality per 100 patient-years were 8.11 (95 % CI: 5.56-11.83) and 30.22 (95 % CI: 22.60-40.42.89), respectively.

CONCLUSION: Patients with cancer and IDDVT are at high risk of developing recurrent VTE and bleeding complications (both major bleeding and CRNMB). More studies are needed to define the optimal management for this high-risk population.

Clonal haematopoiesis of indeterminate potential in patients with venous thromboembolism

J Thromb Thrombolysis. 2023 Jun 10. doi: 10.1007/s11239-023-02836-4. Online ahead of print.

ABSTRACT

Over the last decade, the concept of Clonal haematopoiesis of undetermined potential (CHIP) has emerged. Low frequency somatic mutations in hematopoietic cells can occur with age and might allow formation of clones in individuals with no characterized haematological pathology. These CHIP mutations are associated with an increased risk of cancer or atherothrombosis, and their prevalence are more and more studied in pathologies with an inflammatory component. In our study, we analysed, by next generation sequencing, the prevalence of CHIP mutation in 94 patients with deep venous thrombosis (DVT), distinguishing two clinical phenotypes: provoked distal and non-provoked proximal DVTs. We show that there is no difference in CHIP prevalence between these two groups, nor with a matched-aged control group. The number of mutation per patients and the affected genes remain also the same between the three groups. Consequently and despite the relative small number of patients in each cohort, it seems that CHIP is not a strong concern in venous thromboembolism.

Causal relationships between risk of venous thromboembolism and 18 cancers: a bidirectional Mendelian randomisation analysis

medRxiv. 2023 May 18:2023.05.16.23289792. doi: 10.1101/2023.05.16.23289792. Preprint.

ABSTRACT

Background:People with cancer experience high rates of venous thromboembolism (VTE). Additionally, risk of subsequent cancer is increased in people experiencing their first VTE. The causal mechanisms underlying this association are not completely understood, and it is unknown whether VTE is itself a risk factor for cancer. Methods:We used data from large genome-wide association study meta-analyses to perform bi-directional Mendelian randomisation analyses to estimate causal associations between genetically-proxied lifetime risk of VTE and risk of 18 different cancers. Results:We found no conclusive evidence that genetically-proxied lifetime risk of VTE was causally associated with an increased incidence of cancer, or vice-versa. We observed an association between VTE and pancreatic cancer risk (odds ratio for pancreatic cancer 1.23 (95% confidence interval 1.08 - 1.40) per log-odds increase in risk of VTE, P =0.002). However, sensitivity analyses revealed this association was predominantly driven by a variant proxying non-O blood group, with inadequate evidence from Mendelian randomisation to suggest a causal relationship. Conclusions:These findings do not support the hypothesis that genetically-proxied lifetime risk of VTE is a cause of cancer. Existing observational epidemiological associations between VTE and cancer are therefore more likely to be driven by pathophysiological changes which occur in the setting of active cancer and anti-cancer treatments. Further work is required to explore and synthesise evidence for these mechanisms.

KEY MESSAGES: 1) There is strong observational evidence that active cancer is associated with venous thromboembolism.2) It is currently unknown whether venous thromboembolism is a risk factor for cancer.3) We applied a bi-directional Mendelian randomisation framework to appraise the causal relationships between genetically-proxied risk of venous thromboembolism and 18 different cancers.4) Overall, there was no clear evidence from Mendelian randomisation that lifetime-elevated risk of venous thromboembolism is causally associated with an increased risk of cancer, or visa versa.

Cardiac Metastatic Tumors: Current Knowledge

Am J Clin Oncol. 2023 May 26. doi: 10.1097/COC.0000000000001013. Online ahead of print.

ABSTRACT

Cardiac tumors are a heterogeneous group of pathologic masses of the heart that contain primary tumors-benign or malignant, and secondary tumors. Metastases are significantly more frequent, mostly originating from lung, breast, gastrointestinal tract, or ovary carcinomas. Secondary cardiac tumors may be asymptomatic or may cause cardiovascular, systemic, or embolic symptoms. The study is a summary of the available knowledge on cancerous metastatic lesions of the heart. Pleural mesothelioma (48.4%), adenocarcinoma (19.5%), or squamous cell carcinoma (18.2%) of lung, breast carcinoma (15.5%), ovarian carcinoma (10.3%), and bronchoalveolar carcinomas (9.8%) are cited as the most common origin of secondary heart tumors. Masses can spread by direct tumor invasion, by lymphatic vessels, veins, or arteries. Patients with cancer and nonspecific cardiovascular symptoms should be particularly vigilant, and the possibility of metastasis in an unusual location such as the myocardium should be considered in the diagnosis. Diagnostic methods include echocardiography, cardiac magnetic resonance, computed tomography, positron emission tomography, and histologic evaluation. Treatment of choice is managing primary carcinoma, due to the poor outcomes of surgical methods.

Venous thromboembolism secondary to hospitalization for COVID-19: patient management and long-term outcomes

Res Pract Thromb Haemost. 2023 May;7(4):100167. doi: 10.1016/j.rpth.2023.100167. Epub 2023 Apr 26.

ABSTRACT

BACKGROUND: Venous thromboembolism (VTE) is a complication of COVID-19 in hospitalized patients. Little information is available on long-term outcomes of VTE in this population.

OBJECTIVES: We aimed to compare the characteristics, management strategies, and long-term clinical outcomes between patients with COVID-19-associated VTE and patients with VTE provoked by hospitalization for other acute medical illnesses.

METHODS: This is an observational cohort study, with a prospective cohort of 278 patients with COVID-19-associated VTE enrolled between 2020 and 2021 and a comparison cohort of 300 patients without COVID-19 enrolled in the ongoing START2-Register between 2018 and 2020. Exclusion criteria included age <18<3

RESULTS: Patients with VTE secondary to COVID-19 had more frequent pulmonary embolism without deep vein thrombosis than controls (83.1% vs 46.2%, P<.001),P<.001),P<.001).P= 0.9) and the proportion of patients who discontinued anticoagulation (78.0% and 75.0%, P= 0.4) were similar between the 2 groups. Thrombotic event rates after discontinuation were 1.5 and 2.6 per 100 patient-years, respectively (P = 0.4).

CONCLUSION: The risk of recurrent thrombotic events in patients with COVID-19-associated VTE is low and similar to the risk observed in patients with VTE secondary to hospitalization for other medical diseases.

Ambulatory blood pressure monitoring in patients with onco-hematological diseases

Hipertens Riesgo Vasc. 2023 Jun 9:S1889-1837(23)00033-8. doi: 10.1016/j.hipert.2023.05.006. Online ahead of print.

ABSTRACT

Hypertension (HT) is a frequent pathology in patients with active or surviving onco-haematological malignancies. It is estimated that the prevalence of HT in this population ranges between 30 and 70%. The relationship between cancer and HT is multifactorial: common risk factors, neoplasia that cause HT through hormonal secretion, and, especially, chemotherapy drugs that cause HT. Ambulatory blood pressure monitoring (ABPM) is a fundamental tool in the diagnosis and adequate control of blood pressure, avoiding having to suspend or reduce the dose of chemotherapy treatment. In addition, it can help in the diagnosis of autonomic dysfunction related to certain neoplastic pathologies.

COVID-19 severity and cardiovascular outcomes in SARS-CoV-2-infected patients with cancer and cardiovascular disease

Transl Oncol. 2023 Jun 2;34:101709. doi: 10.1016/j.tranon.2023.101709. Online ahead of print.

ABSTRACT

BACKGROUND: Data regarding outcomes among patients with cancer and co-morbid cardiovascular disease (CVD)/cardiovascular risk factors (CVRF) after SARS-CoV-2 infection are limited.

OBJECTIVES: To compare Coronavirus disease 2019 (COVID-19) related complications among cancer patients with and without co-morbid CVD/CVRF.

METHODS: Retrospective cohort study of patients with cancer and laboratory-confirmed SARS-CoV-2, reported to the COVID-19 and Cancer Consortium (CCC19) registry from 03/17/2020 to 12/31/2021. CVD/CVRF was defined as established CVD or no established CVD, male ≥ 55 or female ≥ 60 years, and one additional CVRF. The primary endpoint was an ordinal COVID-19 severity outcome including need for hospitalization, supplemental oxygen, intensive care unit (ICU), mechanical ventilation, ICU or mechanical ventilation plus vasopressors, and death. Secondary endpoints included incident adverse CV events. Ordinal logistic regression models estimated associations of CVD/CVRF with COVID-19 severity. Effect modification by recent cancer therapy was evaluated.

RESULTS: Among 10,876 SARS-CoV-2 infected patients with cancer (median age 65 [IQR 54-74] years, 53% female, 52% White), 6253 patients (57%) had co-morbid CVD/CVRF. Co-morbid CVD/CVRF was associated with higher COVID-19 severity (adjusted OR: 1.25 [95% CI 1.11-1.40]). Adverse CV events were significantly higher in patients with CVD/CVRF (all p<0.001).interaction

CONCLUSIONS: Co-morbid CVD/CVRF is associated with higher COVID-19 severity among patients with cancer, particularly those not receiving active cancer therapy. While infrequent, COVID-19 related CV complications were higher in patients with comorbid CVD/CVRF. (COVID-19 and Cancer Consortium Registry [CCC19]; NCT04354701).
