This special topic issue addresses the most common endocrine and metabolic complications observed in cancer survivors. It gives an overview to orient endocrinologists to common cancer diagnoses and the therapies most often associated with adverse endocrine outcomes. Additionally, it focuses on the important issues of impaired linear growth, hypogonadism in males and females, disorders of the thyroid gland, diabetes mellitus and the metabolic syndrome, hypothalamic obesity, and disorders of the bone. These state-of-the-art reviews will hopefully assist clinicians in diagnosing and managing the various endocrine disorders experienced by survivors. The goal is to improve quality of life and to reduce morbidity and mortality in a vulnerable population. This publication is a valuable resource for pediatric, adult, and generalist providers caring for childhood cancer and brain tumor survivors.
