Care pathways for patients with cancer-associated thrombosis: From diagnosis to long-term follow-up

Psychoactive drug use and prognosis in patients with cancer presenting with acute cardiovascular disease

BACKGROUND

The psychoactive drug consumption and the short- and long-term cardiovascular prognosis of patients with cancer admitted for acute cardiovascular events are not well established.

AIMS

To assess the prevalence of psychoactive drug use, in-hospital outcomes and 1-year prognosis in patients with cancer hospitalized for acute cardiovascular events.

METHODS

In a prospective multicentre study of all consecutive patients admitted to intensive cardiac care units, a history of cancer was recorded systematically. The primary outcome was the prevalence of psychoactive drugs detected by urine drug assay. The secondary outcomes were: the rate of in-hospital major adverse events, defined as all-cause death, cardiogenic shock and cardiac arrest; and the 1-year rate of major adverse cardiovascular and cerebrovascular events, defined as cardiovascular death, myocardial infarction and stroke.

RESULTS

Among 1499 patients recruited, 151 had a history of cancer (10%), including 61 (40%) with active cancer and 90 (60%) with cancer in remission. Among patients with a history of cancer, 39 (25.8%) tested positive for at least one psychoactive drug. Using a matching approach based on the likelihood of having a cancer, a history of cancer was not associated with an increased risk of in-hospital major adverse events (odds ratio: 1.54, 95% confidence interval: 0.68-3.45; P=0.3). However, a history of cancer was associated with a higher incidence of 1-year major adverse cardiovascular and cerebrovascular events (hazard ratio: 3.04, 95% confidence interval: 1.63-5.67; P<0.001).

CONCLUSIONS

The prevalence of psychoactive drug use among patients with a history of cancer hospitalized for acute cardiovascular events was 25.8%. A history of cancer was an independent predictor of 1-year major adverse cardiovascular and cerebrovascular events.

Care pathway for patients hospitalized with venous thromboembolism

BACKGROUND

Venous thromboembolism (VTE), including pulmonary embolism (PE) and deep vein thrombosis (DVT), is a potentially fatal disease with a multifactorial nature, impacting different medical and surgical specialties. Recently, new guidelines and direct oral anticoagulants facilitated early discharge for most DVT patients and non-severe PE patients.

OBJECTIVE

The aim of this study is to illustrate the distribution of VTE patients throughout the hospital and map their care pathway from Emergency Department (ED) to hospital discharge.

METHODS

This multicenter retrospective cross-sectional study included all hospitalized patients with a VTE code from 39 hospitals between 2018 and 2019. Data were analysed using JupyterLab, with subgroup analyses based on mode of entry, diagnosis location and thrombosis site.

RESULTS

A total of 23,199 hospitalizations were analysed, involving 17,718 patients a median age 66 years [52-78] and man-to-women ratio 1.05. Among these, 10,747(46.3%) had PE and 4176(18.0%) had lower limb DVT. The ED was the primary entry point for 31.2% of cases, followed by gastroenterology, surgery, geriatrics, and internal medicine. Patients admitted through ED patients were most frequently transferred to internal medicine, cardiovascular and intensive care units (ICU). The median hospital stay was 9 days [4-21], with ICU stays being the longest (mean 15 days [8-27]). Notably, 1357 patients (18.8%) of VTE patients were discharged within 48 h of ED admission.

CONCLUSIONS

This study is the first to portray the distribution and care pathways of VTE patients across hospital departments. Despite recent clinical guidelines, many patients still require inpatient management, highlighting the need for dedicated care pathway.

Cancer-associated thrombosis: what is new?

PURPOSE OF REVIEW

The life expectancy of patients suffering from thrombosis associated with cancer has improved significantly, making them a chronic disease. Patients with thrombosis and cancer are fragile. Treated with anticoagulants, they remain at risk of complications.

RECENT FINDINGS

Consequently, news issues emerge for clinical practice: anticoagulation therapy personalization is required to optimize the benefit ratio, involving patient characteristics and cancer characteristics. During follow-up, prediction score are designed and investigated to help identify and discriminate patients at risk of venous thromboembolism recurrences and major bleedings. Considering the improved prognosis of patients with cancer and cancer-associated thrombosis, the question of extended treatment arises, representing a major unmet need to date. Finally, new strategies, in particular anti-XI agents that appear attractive options, are currently being evaluated in the treatment of thrombosis associated with cancer.

SUMMARY

The improved prognosis of patients with cancer-associated thrombosis is accompanied by new therapeutic strategies to improve the benefit-risk ratio of anticoagulant treatment in these fragile patients, at risk of both venous thromboembolic recurrence and haemorrhagic complication.

Venous thromboembolism (VTE) is a frequent and potentially fatal complication in patients with cancer. During the initial period after the thromboembolic event, a patient receiving anticoagulant treatment is exposed both to a risk of VTE recurrence and also to an elevated bleeding risk conferred by the treatment. For this reason, the choice of anticoagulant is critical. The choice should take into account patient-related factors (such as functional status, age, body mass index, platelet count and renal function), VTE-related factors (such as severity or site), cancer-related factors (such as activity and progression) and treatment related factors (such as drug-drug interactions), which all potentially influence bleeding risk, and patient preference. These should be evaluated carefully for each patient during a multidisciplinary team meeting. For most patients, apixaban or a low molecular-weight heparin is the most appropriate initial choice for anticoagulant treatment. Such treatment should be offered to all patients with active cancer for at least 6months. The patient and treatment should be re-evaluated regularly, and anticoagulant treatment changed when necessary. Continued anticoagulant treatment beyond 6months is justified if the cancer remains active or if the patient experienced recurrence of VTE in the first 6months. In other cases, the interest of continued anticoagulant treatment may be considered on an individual patient basis in collaboration with oncologists.

[Translation into French and republication of: "Home treatment for patients with cancer-associated venous thromboembolism"]

Patients hospitalised with acute venous thromboembolism (VTE), and notably patients with pulmonary embolism, often remain in hospital for extended periods due to the perceived risk of complications. However, several studies have shown that home treatment of selected patients is feasible and safe, with a low incidence of adverse events. This may offer clear benefits for patients' quality of life, hospital planning and cost to the health service. Nonetheless, there is a need for a VTE risk-stratification tool specifically addressing prognosis in patients with cancer. This may aid in the selection of low-risk patients with cancer and VTE who are suitable for outpatient treatment. Although several prognostic scores have been proposed, we suggest using a pragmatic clinical decision-making tool such as the Hestia criteria for selecting patients for home care in everyday clinical practice. Once patients have been discharged, it is mandatory to monitor patients regularly (we suggest after 3 days, 10 days, 1 month and 3 months, or more frequently if needed) with the involvement of a multidisciplinary team, so that appropriate and timely remedial action can be taken in case of warning signs of complications. If patients are selected carefully and monitored effectively, many patients who experience acute VTE can be cared for safely at home.
