Abstract:
:Nuclear DNA content of paraffin-embedded tissue from 48 adrenocortical neoplasms, 18 histologically normal control adrenal glands, and five hyperplastic adrenal glands was analyzed retrospectively using flow cytometry. Aneuploidy was compared with morphologic criteria as a predictor of recurrence. All 18 controls, five hyperplastic glands, and 39 neoplasms were diploid. Nine neoplasms were aneuploid. Compared with their diploid counterparts, aneuploid neoplasms were more likely to weigh more than 50 g (P less than 0.0001) and to have three or more histologic features of carcinoma (P less than 0.0001). Thirty-six neoplasms were followed clinically for at least 2 years (range 24 to 120 months, mean = 64.6 months) or until local recurrence, metastasis, or death. Five were clinically malignant. Neoplasms which recurred or metastasized were more apt to be aneuploid (P less than 0.005) than those showing no evidence of further disease during the follow-up period. They were also more likely to weigh more than 50 g (P less than 0.005) and to have three or more histologic features of carcinoma (P less than 0.0025). However, neither aneuploidy, large size, nor unfavorable histology result was a consistent feature in every malignant neoplasm. Flow cytometric DNA content analysis appears to be as effective a predictor of clinical outcome as size and histology and may be of particular value when the morphologic features are ambiguous.
