Cancer Biology of Retinoblastoma

This study has been terminated.

Information provided by (Responsible Party):
Stanford University
ClinicalTrials.gov Identifier:
NCT01642823
First received: July 11, 2012
Last updated: March 2, 2017
Last verified: March 2017
  Purpose
Many children with the childhood cancer, Retinoblastoma, have surgery to remove the tumor and sometimes the entire eye. The purpose of this study is to collect the extra tissue from patients who undergo tumor removal for laboratory experiments that will help us understand not only what occurs in retinoblastoma cells but also how cells normally function. Some of these studies will include an evaluation of how cells control the way that genes are expressed, how cells "know" to become retinal cells, how cells remain retinal cells, how cells lose their identity as retinal cells, what changes make retinoblastoma cells different from normal retinal cells, and what changes make some retinoblastomas worse than others.

Condition
Retinoblastoma

Study Type: Observational
Study Design: Observational Model: Case-Only

Further study details as provided by Stanford University:

Primary Outcome Measures:
  • Change in efficiency of reprogramming in cells with "naturally occurring" retinoblastoma mutations [ Time Frame: After appropriate time, e.g., 7, 10, 14 days after reprogramming ]
    Comparison of number of reprogramming events (defined by colony formation assay and normalized for number of cell plated) as well as the time to reprogramming.
