Early Detection of Imaging-derived Subclinical Cardiac Injuries (EMIRA)

Early Detection of Imaging-derived Subclinical Cardiac Injuries After Radiotherapy and Chemotherapy for Breast Cancer

Breast cancer (BC) radiotherapy leads to incidental cardiac irradiation, resulting in an increased risk of various major cardiac events (MCEs). In addition, recent studies indicate that for the treatment of BC, the addition of chemotherapy further enhances the risk of MCEs. Information regarding morphological and functional early subclinical cardiac injuries (ESCIs) induced by chemotherapy and radiotherapy that develop into MCEs is largely lacking in scientific literature. This information is essential towards the development of primary and secondary preventive strategies. The EMIRA prospective cohort has as main objective to identify morphological and functional ESCIs in BC patients treated with adjuvant radiotherapy and chemotherapy.

Study Overview

• Status: Recruiting
• Conditions: Cardiovascular Diseases
• Intervention / Treatment: Other: Cardiac imaging modalities

Detailed Description

EMIRA is a single centre prospective observational cohort study performed in the UMCG. The study includes breast cancer patients that underwent primary surgery, either by mastectomy or breast conserving surgery, who are treated with adjuvant radiotherapy and chemotherapy as part of routine clinical care. The patient follow up time continues for 2 years after radiotherapy to identify early subclinical cardiac injuries (ESCIs), using repeat echocardiography (cECHO), cardiac MRI (cMRI) scans and cardiac CT (cCT) scans. The images are acquired prior to chemotherapy and/or radiotherapy (depending on the sequence of adjuvant treatment), and at 6 and 24 months after radiotherapy The first primary aim of this project is to detect ESCIs that are considered risk factors for clinically apparent major cardiac events in breast cancer patients treated with radiotherapy and chemotherapy. The second is to use this information to develop prediction models describing the relationship between the radiation dose to cardiac substructures and ESCIs.

In detail, the investigators aim to:

1. identify longitudinal morphological and functional ESCIs using echocardiography, cardiac MRI and cardiac CT before and after BC treatment;
2. determine the relationship between 3D-dose distributions to cardiac substructures and ESCI;
3. establish the effect of chemotherapy on the dose-effect relationship between radiation dose and ESCI.
