Cancer Biology of Retinoblastoma

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT01642823
Recruitment Status : Terminated (Logistics)

Brief Summary:
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.

retinablastoma tumor tissue

Primary Outcome Measures :
  1. 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.
