Oncology
Pediatric oncology focuses on the diagnosis and management of cancer in infants, children, and adolescents. Leukemias, lymphomas, and other hematological malignancies are the most common group of pediatric cancers, followed by brain tumors. Other important pediatric cancers include Wilms tumor, neuroblastoma, sarcomas, histiocytosis, and germ cell tumors. Certain cancers can present with oncologic emergencies, such as tumor lysis syndrome or spinal cord compression, or as part of a cancer predisposition syndrome. With increased survival rates, short- and long-term complications of chemotherapy, radiation, surgery, and hematopoietic cell transplantation are also prevalent and important to recognize. This chapter reviews these key concepts in pediatric oncology using board review–style questions and answers.
