The Childhood Cancer Survivor Study (CCSS) is an ongoing multi-institutional cohort study including approximately 25 700 five-year survivors of the most common types of childhood cancer (leukemia, lymphoma, renal tumors, sarcomas, and central nervous system malignant neoplasms) diagnosed before age 21 years between 1970 and 1999. The CCSS has abstracted cancer treatment exposures within 5 years of diagnosis from treating institutions’ records, including radiation therapy, chemotherapy, and surgical procedures.
