A model of care for childhood cancer survivors that facilitates research.

The majority of children and adolescents diagnosed with cancer will achieve long-term survival after contemporary therapy. Consequent to this success are challenges inherent in coordinating lifelong health care for a group predisposed to a variety of cancer-related complications. With increasing numbers of aging adult survivors of childhood cancer, clinicians now face the additional challenge of studying delayed effects of childhood cancer in the context of organ senescence.

The epidemiology of chronic hepatitis C infection in survivors of childhood cancer: an update of the St Jude Children's Research Hospital hepatitis C seropositive cohort.

Childhood cancer survivors transfused before 1992 are at risk for chronic hepatitis C (HCV) infection. In 1995, St Jude Children's Research Hospital initiated an epidemiologic study of childhood cancer survivors with transfusion-acquired HCV. Of the 148 survivors with HCV confirmed by second-generation enzyme immunoassay, 122 consented to participate in the study.
