PURPOSE: Adolescents with cancer may access oncologic care from pediatric or adult medical centers, given overlapping age eligibility. However, some recent data suggest a benefit to adolescents with certain cancers when treated at pediatric centers or on pediatric protocols. We used a population-based registry to determine the site of care of children, adolescents, and young adults (age 0 to 24 years) with newly diagnosed cancer. PATIENTS AND METHODS: From the Utah Cancer Registry 1994 to 2000, new malignant cases in patients aged 0 to 24 years were chosen; data including diagnosis, home ZIP code and sites of oncologic care were abstracted. Distance between home ZIP code and Primary Children's Medical Center (PCMC; Salt Lake City, Utah), the state's sole site of pediatric oncology care, was determined. RESULTS: Sixty-six percent of Utah 15- to 19-year-olds with cancer were never seen by a PCMC oncologist. Even among this narrow age range, utilization of the pediatric center dropped with each additional year of age. Not unexpectedly, few of those with epithelial malignancies in this age group were seen at PCMC. But surprisingly, 47% of the older adolescents with leukemia, 66% with brain tumors, and 71% with lymphoma never saw a pediatric oncologist. After consideration of age and diagnosis, distance the patient lived from PCMC had a negligible effect on the likelihood of an adolescent being seen there. CONCLUSION: The referral of adolescents with cancer to a pediatric oncology center diminishes greatly with age, and is moderately influenced by diagnosis and minimally by distance from center. Further study should investigate reasons for referral patterns, and impact on outcomes.
