RATIONALE: Studying samples of tissue and bone marrow from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer.

PURPOSE: This research study studies biomarkers in samples from young patients with neuroblastoma.

Further study details as provided by National Cancer Institute (NCI):

Primary Outcome Measures:
  • ROR1 is expressed on the surface of neuroblastoma cells and constitutes a suitable target for mAb therapy [ Designated as safety issue: No ]

Estimated Enrollment: 20
Study Start Date: May 2011
Estimated Primary Completion Date: August 2011 (Final data collection date for primary outcome measure)
Detailed Description:



  • To analyze the expression of ROR1 on the surface of primary neuroblastoma cells.
  • To investigate the therapeutic potential of anti-ROR1 monoclonal antibodies (mAbs), bispecific antibodies, and immunotoxins in in vitro and in vivo models of neuroblastoma.

OUTLINE: Archived bone marrow and tumor tissue samples are analyzed for ROR1 expression by flow cytometry, western blotting, qPCR, and IHC.


Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No


  • Diagnosed with neuroblastoma

    • With or without N-myc amplification
  • Primary tumor samples as frozen tissue in liquid nitrogen or -80 degrees C
  • Bone marrow samples from high-risk patients as peripheral blood mononuclear cells (PBMC) that have been cryopreserved with DMSO as viable cells to be used for flow cytometry or slides of bone marrow that can be used for immunohistochemistry
