The prognostic value of nuclear DNA content in papillary thyroid carcinoma was studied retrospectively in 90 patients. Eighty survived for at least 10 years, and 10 died, of papillary thyroid carcinoma, between 6 months and 12 years after diagnosis. Clinical data as well as morphological tumor characteristics were examined. DNA measurements in morphologically identified single tumor cells were performed either on fine‐needle aspiration material or on histologic sections. The tumors of the survivors were composed of cells with a DNA content comparable to that of normal cells, whereas the tumors of the non‐survivors had significantly higher DNA values. The data suggest that DNA measurements in papillary thyroid carcinoma offer a valuable adjunct to standard clinical and microscopic analysis.
