Flow cytometric DNA analysis of adrenocortical tumors in children.
Flow cytometric DNA analysis of isolated nuclei was performed on 14 lesions occurring in ten children with adrenocortical tumors. Unimodal DNA content distributions were obtained from seven tumors occurring in patients without metastases 2 to 18 years after diagnosis. Abnormal DNA contents were detected in all four primary lesions, which subsequently metastasized, and in the tumor of one patient who was followed for less than 2 years. Paraffin and frozen preparations were virtually identical, as were the analyses of the primary, recurrent, and metastatic disease occurring in one patient. These observations suggest that DNA content abnormalities detected by flow cytometry correlate with metastases, and may provide an objective measure of the biologic potential of these tumors.
