Acoustic neuromas following childhood radiation treatment for benign conditions of the head and neck.

Childhood radiation exposure has been associated with an increased risk for developing several neoplasms, particularly benign and malignant thyroid tumors, but little is known about the risk of developing acoustic neuromas. The aim of this study was to confirm whether there is a risk for acoustic neuromas and, if so, to determine its magnitude and duration. We investigated the time trend and dose-response relationships for acoustic neuroma incidence in a cohort of 3,112 individuals who were irradiated as children between 1939 and 1962.

Familial concordance of thyroid and other head and neck tumors in an irradiated cohort: analysis of contributing factors.

Relatively little is known about variations in susceptibility to the effects of radiation in the general population. We have been studying 4296 individuals exposed as children to head and neck radiation. The present study was designed to evaluate the pattern of thyroid, parathyroid, salivary, and neural tumors in irradiated siblings for evidence of heritable susceptibility factors.

Multiple neoplasms in an irradiated cohort: pattern of occurrence and relationship to thyroid cancer outcome.

We have examined the pattern of four radiation-related neoplasms in a radiation-exposed cohort of 2795 patients. They had received conventional radiation treatments for benign conditions in the head and neck area when they were children. At the end of follow-up, 350 thyroid cancers, 108 benign and malignant salivary tumors, 87 neural tumors, and 70 cases of hyperparathyroidism had occurred.
