Trial summary

Venous thromboembolism is a common and serious complication in cancer, and is associated with a substantially increased morbidity and mortality. Furthermore, VTE may be the earliest sign of cancer. Recent studies, however, fail to show a clinical benefit of extended cancer screening in this patient population. Read more about this study

About this study

Venous thromboembolism is a common and serious complication in cancer, and is associated with a substantially increased morbidity and mortality. Furthermore, VTE may be the earliest sign of cancer. Recent studies, however, fail to show a clinical benefit of extended cancer screening in this patient population. Better risk prediction models are therefore warranted to identify VTE patients who would benefit from a rapid and extensive cancer screening. Inflammation and hypercoagulability are considered hallmarks of cancer, and emerging light is being shed on the potential of various markers of inflammation and coagulation in cancer diagnostics and prognostics. Among the inflammatory and thrombotic processes linked to cancer is the neutrophil release of web-like nuclear chromatin (DNA and histones), referred to as neutrophil extracellular traps (NETs). Driven by the tumor environment, NETs have recently been shown to play a central role in tumor progression, metastasis, and tumor-associated thrombosis.

The investigators hypothesize that an enhanced inflammatory state may be predictive of an underlying cancer in patients presenting with VTE. The present study is an ongoing prospective study with the primary aim to investigate the diagnostic potential of markers of inflammation, including markers of NETs, in detecting occult cancer in patients presenting with VTE. Secondary aims are to include other biomarkers of cancer, and to assess whether any or a combination of these biomarkers may be prognostic of occult cancer, recurrent thrombotic events, mortality, or cancer disease progression in VTE patients with an underlying malignancy.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Cancer

    Patients diagnosed with VTE will be referred for a limited cancer screening according to current guidelines. Cancer diagnosis - if not present at inclusion - will be obtained during a two-year follow-up from hospital records and/or the Swedish cancer registry

    Measured: Within 2 years from study inclusion

Secondary outcomes (3)
  1. Recurrent thrombotic event

    Recurrent thrombotic event (arterial or venous thrombosis) will be obtained during a two-year follow-up from hospital records and/or the Swedish national patient registry

    Measured: Within 2 years from study inclusion

  2. All-cause mortality

    All-cause mortality will be obtained during a two-year follow-up from hospital records and/or the Swedish death registry

    Measured: Within 2 years from study inclusion

  3. Cancer progression among enrolled patients with a cancer diagnosis at study inclusion

    Patients with cancer progression will be identified during a two-year follow-up from hospital records and/or the Swedish cancer registry

    Measured: Within 2 years from study inclusion

Questions about this trial

What is this clinical trial studying?

An observational study of Cancer and Venous Thromboembolism, run by Danderyd Hospital at 2 sites in Sweden.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 20 Dec 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Sweden. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Charlotte Thålin, M.D., Ph.D. (+46709565120, charlotte.thalin@sll.se), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Cancer (time frame: Within 2 years from study inclusion). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Dec 2018.
