Return of Results

Once a clinical trial has been completed, researchers analyze data from all participants and publish trial results in peer-reviewed medical journals to inform future research. These results show how well a treatment performed and how it compares to standard approaches.

In addition to scientific publications, COG shares trial results with all research participants through the Return of Results (ROR) program. ROR offers families a simple way to access plain-language summaries of study findings, including treatment effectiveness, side effects, and patient outcomes. These summaries reflect overall study results and are not specific to an individual patient’s care.

Search for Results

Families can search for clinical trial results in COG’s ROR database using a study keyword or ID and sign up to receive notifications when updates are posted. Updates summarize overall trial outcomes rather than individual patient results. Families with questions about their child’s care should speak directly with their care team.

To search, do one of the following:

  1. Enter the 8-character Study ID (e.g., AREN0533) or Study Title in the “Study ID or Title” field and click “Search”.
  2. Enter a keyword (such as a disease type or drug name) or select a Disease Type from the dropdown to view related studies.
  3. Click “Search” to display a complete list of available COG studies.

Your feedback is appreciated. After reviewing results, you may complete a brief survey available at the end of each summary.
