Groups/Cohorts
Newly diagnosed embryonal tumors The participants in this study are infants (< 3 years of age) with newly diagnosed medulloblastoma, primitive neuroectodermal tumor, or other embryonal tumor, atypical teratoid/rhabdoid tumor, intracranial germ cell tumor, or choroid plexus carcinoma who have received no prior therapy with the exception of steroids and have consented to allow research studies on banked tissue specimens

Groups/Cohorts

Newly diagnosed embryonal tumors

The participants in this study are infants (< 3 years of age) with newly diagnosed medulloblastoma, primitive neuroectodermal tumor, or other embryonal tumor, atypical teratoid/rhabdoid tumor, intracranial germ cell tumor, or choroid plexus carcinoma who have received no prior therapy with the exception of steroids and have consented to allow research studies on banked tissue specimens

Detailed Description:

OBJECTIVES:

Identify known genes that have significantly different levels of expression, using microarray gene chip analysis, in infants with newly diagnosed metastatic vs non-metastatic embryonal central nervous system tumors.
Determine the protein expression of genes identified by microarray analysis that are involved in cellular functions that regulate angiogenesis, invasion, or metastasis in this patient population.
Determine the quantity of gene expression of the confirmed translationally expressed genes using semi-quantitative polymerase chain reaction.

OUTLINE: This is a multicenter study.

Tumor samples are analyzed using microarray gene chip analysis. Differentially expressed genes are evaluated for protein expression by standard immunohistochemistry and/or Western blot analysis, and gene expression is further quantified by semi-quantitative polymerase chain reaction.

PROJECTED ACCRUAL: Approximately 80-100 patients (20-25 with metastatic disease and 60-75 with non-metastatic disease) will be accrued for this study within 4-5 years.

Eligibility

Ages Eligible for Study:	up to 2 Years
