Summary

The Childhood Cancer Survivor Study (CCSS) will investigate the long-term effects of cancer and its associated therapies. A retrospective cohort study will be conducted through a multi-institutional collaboration, which will involve the identification and active follow-up of a cohort of approximately 50,000 survivors of cancer, diagnosed before 21 years of age, between 1970 and 1999 and 10,000 sibling controls. This project will study children and young adults exposed to specific therapeutic modalities, including radiation, chemotherapy, and/or surgery, who are at increased risk of late-occurring adverse health outcomes. A group of sibling controls will be identified and data collected for comparison purposes.

Detailed description

The study will focus on the following objectives: * Characterize survivors' health with respect to disease- and treatment-related factors. * Investigate the consequences of various intensities of exposure to chemotherapy and/or radiation on health outcomes (e.g., cardiovascular, reproductive, second cancers, etc…). * Compare the mortality experience of survivors with the general population. * Characterize the health-related behaviors, patterns of medical care, and medical follow-up needs of survivors. * Describe patterns of familial aggregation of cancer, including known (and variations of) cancer family syndromes. * Collect and store biologic samples (saliva, blood, second tumor tissue) to correlate with health outcomes and use for future research.
