title: [Epidermal growth factor receptors in malignant and benign tumors in children].
abstract: The radioligand technique was used to study the amount of epidermal growth factor receptors (EGFR) in malignant and benign tumors in 32 children aged 8 months to 17 years. The membranous fraction of 11 of the 32 tumors studied showed EGFR equal to 10.1 to 1327 fmol/mg (163.0 +/- 117.5 fmol/mg, median 38.0 fmol/mg). The greatest amount of EGFR was found in breast fibroadenomas. There was no clear relationship of the frequency and level of EGFR expression to a nosological tumor entity in children. A possible role of the EGFR system in tumors in children is discussed.
