Abstract
Our study group consists of more than 40 participants / collaborators including experts in pediatric oncology, cancer predisposition, and guideline preparation, genetic counselor, ethicologists, epidemiologists, and member of the Children’s Cancer Association of Japan. The object is to construct medical system based on precision genetics for patients with pediatric cancer predispositions, and the tasks are to prepare guidelines on medical care and genetic counselling for pediatric cancer predispositions, especially Li-Fraumeni syndrome. Guidelines of medical care and genetic counselling will be developed based on detailed evidences obtained by systematic review of relevant literatures. Furthermore, we will publish summaries of the recommended surveillance systems for pediatric cancer predispositions, which was formulated in the Childhood Cancer Predispositon Workshop of the American Association for Cancer Research in 2016 and published in the journal Clinical Cancer Research in 2017.
