Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 40 to 50 years
  • Women only
  • No healthy volunteers
  • Adult

Study population: Participants will be recruited from a large retrospective cohort of BC patients.

Who may be able to join

  • early invasive BC (TNM stage I - III);
  • diagnosed and/or treated in the AVL or UMCG;
  • treated 5 - 7 years or 10 - 12 years ago;
  • aged 40-50 years at time of therapy;
  • signed written informed consent.

Who cannot join

  • history of RT or CT unrelated to BC;

About this study

Official title: HARBOR Study: Identifying Subgroups With High Cardiovascular Risk in Breast Cancer Survivors

The purpose of this study is to evaluate the prevalence of (sub)clinical cardiovascular disease, cardiovascular risk factors and metabolic abnormalities among long-term breast cancer survivors treated with or without anthracyclines in order to identify patients at increased risk of developing cardiovascular disease.

Read the detailed description

Rationale: Breast cancer (BC) incidence is increasing, while mortality from BC is decreasing. Since the life expectancy of BC patients is improving, the evaluation of treatment-associated cardiovascular disease (CVD) in BC survivors is becoming increasingly important. An excess risk of CVD, mainly due to coronary heart disease (CHD), has been observed after radiotherapy (RT) as administered in the 1960s-1980s. Anthracycline-containing CT and trastuzumab are known to induce cardiotoxicity, especially congestive heart failure (CHF). However, the long-term risks of CVD after anthracycline-containing CT, trastuzumab, hormonal therapy (HT) and contemporary RT techniques have hardly been examined. Furthermore, the potential interaction of these treatment modalities has not been well addressed, and there is limited knowledge about the contribution of classic cardiovascular risk factors and the metabolic syndrome to risk and severity of treatment-associated CVD in BC survivors.

Objectives: • to evaluate the prevalence of (sub)clinical CVD, cardiovascular risk factors and metabolic abnormalities among BC survivors treated with and without anthracyclines in two groups at (a) 5 - 7 years and (b) 10 - 12 years after diagnosis;

  • to prospectively evaluate changes in prevalence of (sub)clinical CVD, cardiovascular risk factors and metabolic abnormalities after two years in the same patients.

Secondary objectives are to evaluate the predictive role of newly developed markers for CVD and to evaluate the effects of other BC treatment modalities, psychosocial outcomes, endocrine function and menopausal status on the risk of developing (sub)clinical CVD.

Study design: multicenter (AVL and UMCG) cross-sectional cohort study with prospective monitoring of the same cohort.

Study population: female BC survivors treated with and without anthracyclines 5 - 7 and 10 - 12 years ago at the AVL or UMCG, aged 40-50 years at time of therapy.

Main study parameter: the difference in (sub)clinical cardiovascular damage between patients treated with and without anthracyclines, as measured by left ventricular function parameters.

Anthracycline treated BC patientsAVL or UMCG patients between the age of 40 - 50 at the time of BC diagnosis and treatment, treated with anthracyclines respectively 5-7 years ago and 10-12 years ago.
Receives: Procedure: 2D tissue doppler echocardiography
Anthracycline naive BC patientsAVL or UMCG patients between the age of 40 - 50 at the time of BC diagnosis and treatment, treated without anthracyclines respectively 5-7 years ago and 10-12 years ago.
Receives: Procedure: 2D tissue doppler echocardiography

What is being measured

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

  1. Left ventricular ejection fraction

    The main study parameter will be the difference in left ventricular ejection fraction between patients treated with and without anthracyclines.

    Measured: up to 12 years after breast cancer diagnosis

Secondary outcomes (4)
  1. Diastolic cardiac function

    To compare diastolic cardiac function as measured by tissue doppler echocardiography (E/e' and E/A ratio) in patients treated with and without anthracyclines.

    Measured: up to 12 years after breast cancer diagnosis

  2. Cardiac deformation

    To compare cardiac deformation as measured by speckle tracking imaging (global longitudial strain, radial strain and circumferential strain) in patients treated with and without anthracyclines.

    Measured: up to 12 years after breast cancer diagnosis

  3. Biomarker assessment

    To compare levels of several (candidate) cardiovascular biomarkers (NT-proBNP, hs-TnT, CRP) in patients treated with and without anthracyclines.

    Measured: up to 12 years after breast cancer diagnosis

  4. Intima media thickness and arterial stiffness

    To compare intima media thcikness and arterial stiffness as measured by vascular ultrasound in patients treated with and without anthracyclines.

    Measured: up to 12 years after breast cancer diagnosis

Questions about this trial

What is this clinical trial studying?

An observational study of Breast Neoplasms and Cardiovascular Diseases, run by The Netherlands Cancer Institute at 2 sites in Netherlands.

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 5 inclusion and 5 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: status not confirmed, as of the sponsor's last update on 31 Oct 2016. 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 Netherlands. 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?

Results are not available in the source record.

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

Contact Flora E. van Leeuwen, Prof. dr. (f.v.leeuwen@nki.nl), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Left ventricular ejection fraction (time frame: up to 12 years after breast cancer diagnosis). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02485626, which also lists 1 linked publication.

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 31 Oct 2016.
