Trial Purpose and Description

Trial 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. 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.


Trial Description

PRIMARY OBJECTIVES:

I. To identify key adverse events developing in patients (cases) with a primary cancer diagnosed at age 21 or younger.

II. To characterize the key adverse events with respect to the nature of the primary malignancy (pathology, stage) and coded details of the therapeutic protocol.

III. To identify treatment-related and demographic risk factors through a direct comparison of the case-group and controls identified from the remaining patients with the same primary diagnosis.

IV. To compare the frequency of mutations or polymorphisms in specific candidate genes in cases and controls, using constitutional DNA and RNA from the cases and controls.

V. To explore the role and nature of gene-environment interaction in the development of key adverse events.

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.


Participation Guidelines

Age:
Up to 21 Years
Gender:
Both

Eligibility Criteria


Inclusion Criteria:

- 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
