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 Children's Oncology Group:

Primary Outcome Measures:
  • ROR1 is expressed on the surface of neuroblastoma cells and constitutes a suitable target for mAb therapy

Enrollment: 20
Study Start Date: May 2011
Study Completion Date: April 2016
Primary Completion Date: April 2016 (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.


Ages Eligible for Study:   up to 120 Years   (Child, Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
Patients diagnosed with neuroblastoma.


  • 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
