Collecting and Storing Tissue From Young Patients With Cancer

PRIMARY OBJECTIVES:

I. Establish and bank cell lines and/or xenografts from pediatric patients with cancer.

II. Establish continuous cell lines, under carefully controlled conditions, from pediatric
patients with cancer.

III. Establish transplantable xenografts in immunocompromised mice from tumor cells that are
difficult to establish as continuous cell lines in vitro.

IV. Create a bank of cell lines and generate sufficient vials of cryopreserved cells for
distribution to investigators with approved COG biology protocols. V. Characterize cell lines
from childhood cancers with respect to DNA short tandem repeat molecular profile as a
?fingerprint? of original cell line identity.

VI. Characterize cell lines for the ability for sustained growth in tissue culture and/or as
mouse xenografts.

VII. Characterize cell lines for mycoplasma contamination. VIII. Characterize cell lines for
expression of molecular makers that confirm the tumor-type of the cell line and the immortal
nature of the cells (telomerase) and the expression of molecular markers that may correlate
with drug resistance.

OUTLINE: This is a multicenter study.

Specimens are stratified according to disease (acute lymphoblastic leukemia vs acute myeloid
leukemia vs lymphoma vs osteogenic sarcoma vs Ewing family of tumors vs rhabdomyosarcoma vs
primitive neuroectodermal tumor vs glioma vs astrocytoma vs rhabdoid tumors vs hepatoblastoma
vs retinoblastoma vs Wilms tumor vs germ cell tumors vs other diagnoses).

Leftover tissue from diagnostic procedures and/or surgery is cryopreserved and banked. Blood
and/or bone marrow are also collected and banked. Cell lines are established and
characterized via reverse-transcriptase polymerase chain reaction and/or flow cytometry for
biomarkers and by DNA fingerprinting. Markers to be identified may include the following:

NEUROBLASTOMA: tyrosine hydroxylase, protein gene product (PGP) 9.5, GD2, HLA class I, and
HSAN 1.2 antigens

EWING FAMILY OF TUMORS: EWS-FLI1, EWS-ERG, and PGP 9.5

RETINOBLASTOMA: interphotoreceptor retinoid-binding protein

ACUTE LYMPHOBLASTIC LEUKEMIA: immunophenotype

ALVEOLOR RHADOMYOSARCOMA: PAX3-FKHR, PAX7-FKHR, and MyoD1

ALL CELL TYPES: telomerase expression including hTR and hTERTMutations of TP53 gene are
detected by flow cytometry and/or immunocytochemistry.

No results of these tests are provided to the patient, the patient's physician, or the
patient's medical records.

Inclusion Criteria:

- All malignant tissues from childhood cancers allowed including the following:

- Brain tumors (all types)

- Tissue should be submitted to CNS Committee Resource labs to be forwarded
for this study, unless instructed otherwise on the COG web site

- Ewing family of tumors

- Rhabdomyosarcomas

- Other soft tissue sarcomas

- Osteogenic sarcomas

- Rhabdoid tumors

- Neuroblastomas

- Viable material for cell culture for neuroblastoma is collected via
COG-ANBL00B1 and should not be submitted via this study unless the patient
cannot be enrolled on COG-ANBL00B1*

- Retinoblastomas

- Anaplastic Wilms tumor

- Germ cell tumors

- Leukemias/lymphomas

- Acute myeloid leukemia (AML)

- Blood samples and bone marrow samples from patients at second relapse
and beyond may be submitted for this study

- Bone marrow samples at diagnosis or first relapse must be submitted to
an AML resource lab and will be forwarded for this study at the
discretion of the AML Committee

- Acute lymphoblastic leukemia (ALL)

- Blood samples may be submitted directly to this study

- Bone marrow samples must be submitted to an ALL resource lab and will
be forwarded for this study at the discretion of the ALL Committee

- Enrolled on a COG therapeutic, biology, or tissue banking protocol that allows
collection of tissue for research and submission to a COG-designated resource
laboratory

- Participation in this protocol is not permitted until after tissue requirements
for any active COG disease-specific therapeutic, biology, or banking protocols
have been satisfied

- Material may only be submitted for this protocol if tissue is available in excess
of that required for satisfying active disease-specific therapeutic and
biological protocols

- Patients with diagnosis pending are eligible
