Adolescent and young adult cancer: principles of care.

Adolescents and young adults (ayas) with cancer in active treatment face a number of barriers to optimal care. In the present article, we focus on the 3 critical domains of care for ayas-medical, psychosocial, and research-and how changes to the system could overcome barriers. We summarize the current literature, outline recommended principles of care, raise awareness of barriers to optimal care, and suggest specific changes to the system to overcome those barriers in the Canadian context. Many of the recommendations can nevertheless be applied universally. These recommendations are endorsed by the Canadian Task Force on Adolescents and Young Adults with Cancer and build on outcomes from two international workshops held by that group.
