Study of Late-Occurring Complications in Childhood Cancer Survivors

Overview

About this study

This clinical trial is studying cancer survivors to identify those who are at increased risk of developing late-occurring complications after undergoing treatment for childhood cancer. A patient's genes may affect the risk of developing complications, such as congestive heart failure, heart attack, stroke, and second cancer, years after undergoing cancer treatment. Genetic studies may help doctors identify survivors of childhood cancer who are more likely to develop late complications.

Diagnosis of primary cancer at age 21 or younger, irrespective of current age
No prior history of allogeneic (non-autologous) hematopoietic cell transplant
Development of one of the following key adverse events at any time following initiation of cancer therapy:
- Cardiac dysfunction; Please Note: case enrollment has been closed due to achievement of target accrual
- Ischemic stroke (IS)
- Subsequent malignant neoplasm (SMN)
- Avascular necrosis (AVN); Please Note: case enrollment has been closed due to achievement of target accrual
Submission of a blood specimen (or in certain cases a buccal cell specimen) to the Clinical Pharmacokinetics Laboratory at St. Jude Children's Research Hospital as per the requirements; Please Note: if a patient is currently receiving active cancer treatment, it is preferable to obtain the blood sample at a time when the patient's WBC is > 2,000
Written informed consent from the patient and/or the patient's legally authorized guardian, obtained in accordance with institutional policies approved by the U.S. Department of Health and Human Services
In active follow up by a COG institution; active follow up will be defined as date of last visit or contact by a COG institution within the past 24 months; any type of contact, including contact specifically for participation in ALTE03N1, qualifies as active follow-up; Please Note: treatment on a COG (or legacy group) therapeutic protocol for the primary cancer is NOT required
