Survivors of childhood cancer are at increased risk for late effects of cancer therapy, but evidence suggests that adherence to follow-up care is suboptimal. Here, we review the barriers to adherence, including those unique to childhood cancer survivors, and the rationale for distribution of a survivorship care plan. We also discuss advantages and potential limitations of delivering survivorship care plans via web-based platforms, and describe the unique features of one of these platforms, Passport for Care. A baseline survey directed toward survivors and conducted through Passport for Care found that a significant proportion of survivors are unaware of their specific health risks resulting from cancer and its treatment, and compared with their parents, are less afraid of the risks of recurrence and of cancer therapy-associated late effects (n = 528). Web-based platforms such as Passport for Care have enormous potential for improving access to health information, as well as for enhancing patient, family caregiver, and healthcare provider awareness of both risks of late effects and recommended surveillance. Results from this survey also suggest the potential utility of leveraging these tools to conduct additional research on consenting survivors.
