Formal cancer survivorship care is a growing focus internationally. This article provides a broad overview of the national strategies currently in progress for the development of survivorship programs and care plans within the United States and across Europe. The different approaches taken in their implementation, staffing, and clinical focus are highlighted, with an emphasis on how they are incorporated into various models of care. The considerable variation in making survivorship a formal period of care across countries and health care systems is discussed, including the factors influencing these differences. A review of research focused on the evaluation of definitions and outcomes is provided along with a discussion of important areas requiring future research. (C) 2013 American Cancer Society.
