Cancer therapy can place childhood cancer survivors at increased risk for heart disease which can lead to significant illness or early death. Interventions that occur late in the evolution of treatment-related heart disease are usually ineffective at preventing its progression to death or heart transplant. Our team will work in several research cores to test new imaging and biomarker methods that will lead to earlier detection of heart disease before clinical symptoms develop or it become apparent on standard imaging tests. We will evaluate the importance of genetic differences between individuals in determining who is at greatest risk of developing heart disease as a result of exposure to cardiotoxic agents. We will combine this genetic information with the novel imaging and biomarker methods to predict which children are at particular risk. These vulnerable children can then be targeted by modifying their cancer therapy to reduce their exposure to cardiac toxins, or introducing medications that protect the heart from chemotherapy damage. This team brings together the expertise of clinicians and scientists in pediatric oncology, pediatric and adult cardiology, radiation oncology, genetics, and biostatistics. This is a cross-Canada initiative that will leverage the latest knowledge about cardiac toxicity and create a resource for ongoing research into this important cause of morbidity and mortality in childhood cancer survivors.

| Eligibility |
ACUTE COHORT: Inclusion Criteria: - Aged <18 years at time of cancer diagnosis - Diagnosed with a new malignancy (patients with a history of a prior malignancy wlil be eligible if they have not received any anthracycline chemotherapy or chest radiation) - Cancer treatment plan will require therapy with at least one dose of any anthracycline - Planned to have all pre-anthracycline echocardiograms (ECHO) at the recruiting site - Normal cardiac functioning prior to initiation of anthracycline therapy (LV EF > 55%) - Patients who are uncooperative during the ECHO without sedation or anesthesia will be included in the study. However, these patients will only undergo clinically indicated echocardiograms, with no echocardiograms added for purely research purposes - Provision of signed informed consent by the patient and/or patient's legal guardian Exclusion Criteria: - Patients who were previously treated with anthracycline chemotherapy or radiation to the chest. - Significant congenital heart defects, including patients with any other congenital cardiac abnormality, except those with a patent foramen ovale or a small ASD. Patients with familial cardiomyopathies (hypertrophic, dilated and restrictive) will be excluded. SURVIVOR COHORT: Inclusion Criteria: - Aged < 18 years at time of cancer diagnosis - Previously diagnosed with cancer and currently in remission - Patients whose prior treatment plan included therapy with at least one dose of any anthracycline - Patients who completed their final dose of anthracycline at least 3 years ago - Routinely followed at the recruiting site approximately ever 12 months Exclusion Criteria - Prior allogeneic stem cell transplant - Significant congenital heart defects, including patients with any other congenital cardiac abnormality, except those with a patent foramen ovale or a small ASD. Patients with familial cardiomyopathies (hypertrophic, dilated and restrictive) will be excluded. |
