Overview
This multicenter, prospective cohort study evaluates early cardiac dysfunction in adult survivors of childhood cancer. The hypothesis of this study is that cardiac dysfunction can be detected earlier when using speckle tracking echocardiography as novel echocardiographic technique compared to conventional echocardiography.
Description
Cardiovascular disease including cardiac dysfunction is the leading non-malignant cause of death in childhood cancer survivors. Early detection of cardiac dysfunction is important to identify those in need for medical intervention to improve outcome. This study invites adult childhood cancer survivors to a clinical appointment to the University Hospital Bern, Switzerland. A detailed, standardized cardiac assessment including conventional and novel echocardiographic techniques (speckle tracking) as well as cardiopulmonary exercise testing is performed. Cardiac dysfunction is evaluated in survivors who have had cardiotoxic cancer therapy with anthracyclines and/or chest radiation (high risk) and in survivors who have had chemotherapy other than anthracyclines (standard risk).
Eligibility
This prospective cohort study is nested within the Childhood Cancer Registry (ChCR), a
national, population-based cancer registry that includes all children and adolescents in
Switzerland who were diagnosed with cancer at age 0-20 years. It includes patients
diagnosed with leukemia, lymphoma, central nervous system tumors, and malignant solid
tumours or Langerhans cell histiocytosis. Childhood cancer survivors have survived at least
5 years from cancer diagnosis.
Inclusion Criteria:
- Registered in the ChCR
- Formerly treated at the Department of Pediatric Hematology/Oncology of one of five
participating centers
- Treated with any chemotherapy and/or chest radiation
- Survived ≥ 5 years since most recent cancer diagnosis (primary cancer, relapse(s),
secondary cancer) at time of examination
- Diagnosed at age ≤ 20 years
- ≥ 18 years of age at time of study participation
- Resident in Switzerland
- Written informed consent
Exclusion Criteria:
- Study participants will be excluded if they do not meet the above mentioned inclusion
criteria or refuse to participate in the study.
