The Children's Oncology Group Long-Term Follow-Up Guidelines for Survivors of Childhood, Adolescent, and Young Adult Cancers: A Review.

Abstract

Importance: Since 2003, the Children's Oncology Group (COG) has developed and disseminated the Long-Term Follow-Up Guidelines for Survivors of Childhood, Adolescent, and Young Adult Cancers. These guidelines have benchmarked the standard of care for long-term survivors of childhood cancer in North America and beyond. Since their inception, they have evolved in depth, scope, and contributors to maintain fidelity toward continually emerging evidence related to cancer survivorship. They are intended to inform care for individuals who survived 2 or more years from completion of childhood, adolescent, and young adult cancer-directed therapy and receiving care in either specialty or primary care environments. The guidelines are updated on a 5-year cycle, during which comprehensive literature searches pertaining to guideline-specific questions are performed, evidence abstracted from pertinent publications, and recommendations determined and scored following expert deliberation.

Observations: Version 6.0 of the guidelines, released in October 2023, comprised 165 sections and 45 health links and represents the cooperative efforts of 220 individuals. Major changes include the addition of recommendations regarding surveillance for genetic cancer predisposition, surveillance following the use of novel cancer treatment modalities, and routine vaccination practices during long-term follow-up. In addition, surveillance echocardiograms were omitted for those at low risk of cardiomyopathy.

Conclusions and relevance: This narrative review outlines the historical evolution of the COG Long-Term Follow-Up Guidelines for Survivors of Childhood, Adolescent, and Young Adult Cancers, current methods guiding their development, and key recommendations from version 6.0. The guidelines are publicly available in their entirety online. The COG guidelines continue to set the standard for surveillance practices for long-term survivors of childhood, adolescent, and young adult cancer. The growing body of evidence supporting these recommendations will continue to guide their evolution to inform optimal survivorship care practices.
