| Purpose: |
|
RATIONALE: 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.
PURPOSE: 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.

| Study Summary: |
|
OBJECTIVES:
- Identify key late-occurring complications, specifically, cardiac dysfunction (closed to
accrual as of 4/17/09), myocardial infarction (closed to accrual as of 6/5/06),
ischemic stroke, avascular necrosis (closed to accrual as of 11/26/08), and subsequent
malignant neoplasm, in childhood cancer survivors.
- Correlate key late-occurring complications with pathology and staging of the primary
malignancy and therapeutic treatment protocol details in these patients.
- Identify treatment-related and demographic risk factors by comparing patients who
develop late-occurring complications (case group) vs those with the same primary
malignancy who do not develop late-occurring complications (control group).
- Compare the frequency of mutations or polymorphisms in specific candidate genes in both
the case and control groups using constitutional DNA and RNA from both groups.
- Explore the role and nature of gene-environment interaction in the development of
late-occurring complications in these patients.
OUTLINE: This is a multicenter study.
DNA from peripheral blood or buccal sample of patients is analyzed for the presence of
polymorphisms in candidate genes associated with an increased risk of late-occurring
complications, such as cardiac dysfunction (closed to accrual as of 4/17/09), myocardial
infarction (closed to accrual as of 6/5/06), ischemic stroke, avascular necrosis (closed to
accrual as of 11/26/08), and subsequent malignant neoplasms.
Patients also complete a questionnaire detailing family history and health history.
PROJECTED ACCRUAL: A total of 6,900 patients (1,725 with late-occurring complications [case
group] and 5,175 without late-occurring complications [control group] [myocardial infarction
patients closed to accrual as of 6/5/06, avascular necrosis patients closed to accrual as of
11/26/08, cardiac dysfunction patients closed to accrual as of 4/17/09]) will be accrued for
this study.
