General Background and Study Goal

Great progress has been made in treating children with cancer. With this success comes the need to monitor patients' health status and quality of life years after treatment ends. The COG Long-Term Follow-Up Center was established to improve the collection of follow-up information on survivors of childhood cancer.

The overall goal of this study is to keep in contact with participants of COG clinical trials so that up-to-date information is available on these participants as they get older. This information includes the participant's current contact and health status information, as well as the contact information of the participants' parents and another family member or close friend. While social security and driver's license numbers are requested, this information is optional.

Summary of the Treatment

  • The Long-Term Follow-up Center will contact you regularly to update your contact and health status information.
  • You may be invited to participate in long-term follow-up research studies.

Risks and Side Effects

All risks and side effects will be explained by your study team during the consent process. They can answer any questions that you may have about giving permission to be in the study. The study consent form has more details about possible risks and side effects of this study.
