Comparison of nuclear DNA content in primary and metastatic papillary thyroid carcinoma.
Nuclear DNA values were determined in 40 primary papillary thyroid carcinomas, as well as in 52 corresponding local recurrences and metastases were observed either at the time of diagnosis or up to 20 years later. The patient population consisted of 34 survivors and 6 nonsurvivors. In survivors, both the primary tumors and their recurrences and metastases exhibited a majority of cells with DNA values within the normal diploid region, whereas nonsurvivors showed increased and scattered DNA values. In all cases, the primary tumors and the corresponding recurrences and metastases showed similar DNA distribution patterns even if many years had passed between the detection of the primary tumor and the metastases. The results indicate that in papillary thyroid carcinomas, the DNA distribution patterns in the primary tumor and the corresponding recurrences or metastases are generally similar throughout the entire period of disease.
