CNS Tumors in Adolescents and Young Adults: The Need for a Holistic Specialized Approach.

CNS tumors are one of the most common causes of cancer-related death in the 15- to 39-year-old age group. The management of adolescents and young adults (AYAs) who are diagnosed with brain tumors presents unique endocrine, developmental, and psychosocial issues. AYAs are frequently diagnosed late, after a prolonged period of misdiagnosis. The epidemiology, biology, prognosis, and overall management of these tumors differ from those of both older and younger age groups. AYAs are usually in a transitional phase in their lives, and brain tumors in this age group carry a better prognosis than in older adults; thus, special attention should be paid to survivorship care. Fertility and other treatment-related sequelae that affect the quality of life, as well as the increased risk of secondary malignancies in long-term survivors, are such examples. Although most AYAs are managed by adult or, to a lesser extent pediatric, oncologists, a multidisciplinary approach in the setting of specialized centers with increased participation in clinical trials is preferable. End-of-life and palliative care remain an unmet need for these patients, because most physicians lack the training to discuss such issues with young patients.
