title: Malignant solid tumors in neonates: a 40-year review.
abstract: To evaluate the outcome of neonatal malignant solid tumors, we reviewed the records of 222 infants under the age of 1 year with malignant disease who were treated at the University of Texas M.D. Anderson Cancer Center over a 40-year period. Forty-five cases of neonatal (< 30 days old at the time of presentation) malignancies were found. Thirty-two infants had solid tumors and form the basis of this report. Diagnoses included soft tissue sarcoma (13), brain tumor (5), neuroblastoma (6), retinoblastoma (3), malignant melanoma (2), hemangiopericytoma (2), and nephroblastoma (1). The mean age at which initial signs and symptoms were noted was 9 days of life. Fifty-nine percent (19) presented within the first week of life, and 47% (15) presented at birth. The mean age at histological diagnosis was 54 days. The head and neck region was the most common site (18), followed by trunk (9), and extremities (5). Thirty-one patients underwent surgical resection of the primary tumor. Thirteen of those neonates received no additional chemotherapy and/or radiation therapy, whereas 18 received some combination of surgery plus perioperative chemotherapy and/or radiation therapy. Overall survival was 78% (25 of 32) with an average follow-up of 8 years (range, 2 months to 29 years). There were no survivors among those patients with distant metastatic disease at the time of diagnosis. Despite delays, prognosis is excellent in the absence of distant metastatic disease, particularly for extracranial tumors.
