Purpose : To evaluate the possible role of DNA content abnomrality in solid tumors as a diagnostic indicator in Korean patients, the incidence of aneuploidy in the major organs were analyzed and compared with the incidences which have been reported in the literatures.

Materials and Methods : Flow cytometric analysis of DNA content were performed on the 1673 fresh tissues of neoplastic lesions which were obtained for the last five years in Hospital.

Results : The frequency of aneuploidy was more than 50% in the primary malignant tumors of the stomach, colon, esophagus, liver, biliary tract, pancreas, head and neck organs, salivary gland, lung, breast, ovary, CNS and urinary tract. However, the
frequency of aneuploidy was as low as 7% in papillary carcinoma of thyroid and about
30% in renal cell carcinoma and malignant lymphomas. High frequency of aneuploidy
(more than 70%) was seen in the metastatic tumors in liver, brain, ovary and lymph
nodes. Aneuploidy was also found in benign tumors of salivary gland, adenomas of
endocrine organs, meningiomas, smooth muscle tumors and schwannomas.

Conclusion : The results of present study were in concordant with those of the other domestic and foreign studies. Although aneuploidy can be observed in some benign
tumors, DNA ploidy pattern is considered to be an important diagnostic and prognostic
factors in malignant lesions of the various organs.
