Abstract
Because of improvements in the treatment of childhood cancer in the past several decades, the survival rate of patients is between 60 and 90%. With the increase of long-term survivors, the late effects have become a new problem. We have found that it is difficult to grasp the state of the physical and psychological problem, because of the construction of the regular long-term follow-up system off-treatment. As the result of questionnaires, we understood the patient's and family's anxiety about late effects and the necessity for construction of long-term follow-up systems as soon as possible.
