  • 1. Original ArticleCritical Issues in Transition and Survivorshipfor Adolescents and Young AdultsWith Cancers*Paul C. Nathan, MD, MSc1; Brandon Hayes-Lattin, MD2; Jeffrey J. Sisler, MD, MCISc3,4; and Melissa M. Hudson, MD5 The majority of children, adolescents, and young adults diagnosed with cancer will become long-term survivors with many potential years of life ahead of them. Their journey from health through diagnosis and treatment to survivorship involves multiple transitions. Transitional services that should be available throughout this journey include health- related education, health surveillance and screening, management of cancer-related complications, and psychosocial support relevant to their developmental needs. Survivors require lifelong care that focuses not only on the medical risks arising from their cancer therapy, but also the psychosocial, educational, and vocational implications of surviving cancer. Because many community health care providers lack familiarity with the health risks associated with childhood or adolescent/young adult cancer, survivors must have sufficient health knowledge to advocate for risk-based cancer- related follow-up; the provision of a treatment summary and care plan at the conclusion of their cancer therapy is an important tool for facilitating this process. The availability of resources for survivors varies by geography, health care system, and survivor characteristics. Adolescents and young adults who receive their care outside of a pediatric cancer center have particularly limited access. The limitations in cancer center resources (along with survivor preference) strongly suggest that the long-term care of survivors will need to be shared between the cancer centers and primary care providers in survivors’ communities.

C KEYWORDS: survivorship, transition, cancer, pediatric, adolescent, young adult.The impact of the diagnosis and treatment of cancer on long-term health outcomes in children has received much attentionover the past decade.1 Until recently, less attention was focused on the burden of cancer on adolescents and young adults, whoface unique challenges from diagnosis through survivorship. In 2006, the US National Cancer Institute (NCI) published a reportfrom the Adolescent and Young Adult Oncology Progress Review Group, which highlighted the finding that unlike younger orolder cohorts, those diagnosed with cancer between ages 15 and 39 years have seen little to no improvement in cancer survivalrates for decades.2 This new focus on the adolescent/young adult population was reflected in the Canadian Cancer Society’s pub-lication, Canadian Cancer Statistics 2009, which featured ‘‘Cancer in Adolescents and Young Adults (15-29 Years)’’ as a SpecialTopic.3 The vast majority of patients diagnosed with cancer as an adolescent/young adult will become long-term survivors. From1997 to 2004, the 5-year overall survival for those diagnosed with cancer between ages 15 and 29 years in Canada was 83%.3 It is important to consider the definition of the adolescent/young adult group, as the incidence of cancer increaseswith age. In Canada, there is an average of 2075 new cancer cases per year diagnosed between ages 15 and 29 years, com-pared with only 836 cases between ages 0 and 14 years. An expansion of the definition of adolescent/young adult to thosediagnosed between ages 15 and 39 years, which matches the definition of the NCI’s Progress Review Group, wouldCorresponding author: Dr. Paul C.
