Survivors of childhood cancer may develop a second malignant neoplasm during adulthood and therefore require regular surveillance.

To examine adherence to population cancer screening guidelines by survivors at average risk for a second malignant neoplasm and adherence to cancer surveillance guidelines by survivors at high risk for a second malignant neoplasm.

Retrospective cohort study.

The Childhood Cancer Survivor Study (CCSS), a 26-center study of long-term survivors of childhood cancer that was diagnosed between 1970 and 1986.

4329 male and 4018 female survivors of childhood cancer who completed a CCSS questionnaire assessing screening and surveillance for new cases of cancer.

Patient-reported receipt and timing of mammography, Papanicolaou smear, colonoscopy, or skin examination was categorized as adherent to the U.S. Preventive Services Task Force guidelines for survivors at average risk for breast or cervical cancer or the Children's Oncology Group guidelines for survivors at high risk for breast, colorectal, or skin cancer as a result of cancer therapy.

In average-risk female survivors, 2743 of 3392 (80.9%) reported having a Papanicolaou smear within the recommended period, and 140 of 209 (67.0%) reported mammography within the recommended period. In high-risk survivors, rates of recommended mammography among women were only 241 of 522 (46.2%) and the rates of colonoscopy and complete skin examinations among both sexes were 91 of 794 (11.5%) and 1290 of 4850 (26.6%), respectively.

Data were self-reported. Participants in the CCSS are a selected group of survivors, and their adherence may not be representative of all survivors of childhood cancer.

Female survivors at average risk for a second malignant neoplasm show reasonable rates of screening for cervical and breast cancer. However, surveillance for new cases of cancer is very low in survivors at the highest risk for colon, breast, or skin cancer, suggesting that survivors and their physicians need education about their risks and recommended surveillance.
