The purpose of this study was to obtain suggestions for nursing by reviewing the literature on nurses' decision-making support regarding treatment and recuperation for adolescent cancer patients. Using the Central Journal of Medicine, we searched for “adolescent”, “pediatric”, and “cancer” by combining “decision making” or “informed consent”, “informed assent”, and “nursing”, and included six studies that matched the research objectives. The six target literature were organized and classified into review sheets. As a result, as a decision-making support for adolescent cancer patients, nurses provided explanations according to the child's level of understanding and psychological state, respected the child's wishes and intentions, and created an environment where the child did not feel lonely and could consult at any time. The nurse explained the disease, treatment, and what could happen to their body in the future in a way that was tailored to each child, according to the child's level of understanding and psychological state. In addition, although adolescent children are still under parental advocacy, their parents' opinions are more likely to be reflected, but nurses tried to understand their children's wishes, intentions, and how to express their intentions. In addition, they created opportunities for them to think together when choosing from the information provided and to share their feelings with the adults around them, and created an environment that supports children not only by nurses but also by various professions such as clinical psychologists.
