AbstractWith contemporary therapy, the majority of children and adolescents who are diagnosed with cancer will be cured. However, curative therapy predisposes to adverse health outcomes that affect the long-term survivor's quality of life and increase the risk of early mortality. Recognition of the adverse effects of cancer treatment on growth and development, vital organ function, fertility and reproduction, and secondary carcinogenesis has been the stimulus for the development of risk-adapted treatment approaches for pediatric malignancies. Because the consequences of these therapeutic modifications may not manifest for many years, long-term follow-up is required to accurately define new or changing patterns of adverse health outcomes, appropriate screening approaches, and ultimately, risk-reducing interventions. Identification of vulnerable survivors is essential to provide timely interventions to detect, ameliorate, reduce, or prevent cancer-related sequelae. This process is challenging, because risk factors constantly are evolving as cancer therapies are modified and as survivors age. Aging also disrupts the continuity of after-cancer care, as adolescent and young adult survivors graduate from pediatric oncology practices to community medical providers who are largely unfamiliar with cancer-related health risks. Health outcomes research objectives that target cancer survivors must adapt as cancer therapies evolve and as new risk factors for cancer-related morbidity emerge. Prospectively using a multidimensional, comprehensive approach that considers host-related, cancer-related, genetic, and lifestyle factors in combination with results from focused medical and behavioral evaluations obtained from cancer survivors who participate in long-term follow-up programs provides an optimal method of defining high-risk profiles for adverse health outcomes across the age spectrum.
