Cancer in neonates: the experience at the Children's Hospital of Philadelphia

Abstract

Among 22 neonates treated at the Children's Cancer Research Center of Philadelphia, 11 had neuroblastoma, which in two cases was widely metastatic. There were three infants with teratoma, three with sarcoma, three with leukemia, one with Wilms' tumor, and one with parotid carcinoma. Nine of eleven patients (82%) are long-term survivors following complete surgical excision of tumor, whereas only one of eight (13%) has survived following incomplete surgical excision. All three neonates with leukemia died. The overall two-year actuarial survival is 45% (10/22). The problems associated with treating neonates with chemotherapy, radiation therapy, or both are especially difficult because of the immaturity of the organs and structures. Surgical excision alone has been the treatment of choice for solid tumors. Chemotherapy or radiation therapy, when indicated, require careful monitoring for both acute toxicities and potential long-term morbidities.
