Background and study aims
Breast cancer is one of the most common cancers. In the UK 150 people per day are diagnosed. Often breast cancer is treated with anti-cancer drugs, called chemotherapy. Anthracyclines are a type of chemotherapy often used to treat breast cancer and are very effective. However, as with all drugs anthracyclines come with side effects. Heart damage is the most serious side effect. Heart damage can happen at the time of treatment, but symptoms only develop much later. Detecting heart damage relies on heart scans (called echocardiography, or echo for short). The usual measurements can only identify heart damage when it is already established. Waiting until damage is established means a reduced chance of heart recovery. Unfortunately, anthracycline heart damage can sometimes be severe and affect length and quality of life. Doctors and patients need better ways of detecting heart damage earlier. This study aims to understand if new echo measurements can be used to detect heart side effects sooner. It is not yet known whether these new measurements are better than what is currently done. Some patients are already involved in a linked study called PROACT. These patients have already given their permission for echo studies and analysis. The plan is to ask another group of patients receiving chemotherapy as part of standard care but not currently in PROACT, to participate in this study, called the PROACT PLUS registry.
Who can participate?
Patients aged 18 and over with breast cancer who are going to receive anthracycline-based treatment
What does the study involve?
There are no additional treatments involved in this study, but patients undergo additional echo scans and blood tests (called troponin). The additional echo analysis is performed on normal echo pictures and is called the PROACT echo sub-study. The plan is to follow up the registry patients for 18 months and to combine the information from both trial and registry groups to answer the study questions.
What are the possible benefits and risks of participating?
The benefit to participants is additional heart monitoring that is not routine for all breast cancer patients undergoing treatment with anthracyclines. Patients studied in the registry will be receiving anthracycline-based chemotherapy and/or Herceptin as part of their routine cancer care. The risks and burdens posed on patients from taking these drugs include: nausea, vomiting, tiredness, low white cell count, infection, diarrhoea, and abdominal or joint pains. Participation in the registry does not pose any major risks to patients due to the observational nature of the study. Furthermore no study-specific medication will be given to patients during this period. Blood sample taking could cause some discomfort and distress for patients. There is a very small risk of infection or bleeding at the site of blood taking but the risks of these are extremely small and rare. Where possible, study blood samples will be taken alongside samples taken for routine care. Echocardiography may cause some discomfort at the probe site due to some pressure used when taking the images. No radiation risk is involved in taking the scans.

| Intervention | PROACT PLUS registry and echo-substudy is a multicentre, observational, prospective cohort study assessing the use of novel echocardiographic tools and measurement of troponin to help detect early signs of cardiotoxicity. This registry is complimentary to the NIHR-funded PROACT clinical trial which is currently ongoing in the Northeast of England. PROACT (PRevention Of Anthracycline Cardiovascular Toxicity in patients treated for breast cancer, PB-PG-0815-20061, NCT03265574, IRAS ID 213348) is a multicentre, phase 3, randomised, open label, blinded endpoint study that aims to assess the effectiveness of enalapril in preventing cardiotoxicity in patients with newly diagnosed breast cancer requiring anthracycline based chemotherapy. One hundred and seventy patients, in whom high-dose anthracycline chemotherapy is planned will be randomised to either usual care plus enalapril or usual care. The primary end point is the presence of detectable troponin T (14ng/L or greater), measured at the end of each chemotherapy cycle and 4 weeks after chemotherapy. As part of the assessment of key secondary endpoints in the trial, transthoracic echocardiography will be performed at two time points using a standardised British Society of Echocardiography (BSE) template: prior to commencing chemotherapy, and 1 month after the completion of anthracycline chemotherapy. Trial echocardiographic secondary endpoints include the established measures of LVEF and global longitudinal strain (GLS). The PROACT PLUS registry includes adult patients with newly diagnosed breast cancer who are planned to receive anthracyclines either in an adjuvant or neo-adjuvant setting for their treatment. Patients will not be eligible for inclusion in the registry if they meet the inclusion criteria for the PROACT clinical trial or have metastatic breast cancer. Therefore, the PROACT PLUS registry is complementary to the PROACT clinical trial and eligibility for trial or registry is mutually exclusive. The aim is to include 85 patients, which will be the same number as a single arm in the PROACT trial. A patient information sheet will be provided and any uncertainties about the registry raised by the patient will be addressed. After all questions are answered, the patient will be asked to sign the consent form to confirm participation. Once patient has agreed to participate they will undergo a series of assessments during their treatment as described below: 1. Review of medical history 2. Height and weight measurement 3. Blood pressure and heart rate 4. Blood samples for troponin measurement (prior to each chemotherapy cycle, 4 weeks and 12 months after the last dose of anthracyclines) 5. Blood samples for future research (prior to cycle 1, 3 and 5 and 4 weeks and at least 12 months after the last dose of anthracyclines) 6. Heart scan (echocardiogram) at baseline, 4 weeks and 12 months after anthracyclines 7. Cheek swab for DNA analysis (optional): will be done once only during the registry period No study specific drugs will be given to patients in the registry. The assessments in the registry will mirror the assessments in the PROACT clinical trial to allow a direct comparison of patients within and in both groups. The combined PROACT trial and PROACT PLUS registry data obtained from this cohort of patients with breast cancer will help inform the future of cardiovascular care in patients treated with anthracyclines and can lead to further useful research in the field of cardio-oncology. |
