The relation between the results of cytophotometric examination of endometrial carcinoma and clinical course of these disease.

We made a prospective cytophotometric study of 48 cases of endometrial carcinoma. Thirty-two (66.7%) of the cases had diploid DNA content and the proportion of non-diploid tumors increased with the staging of tumors, lack of differentiation and depth of myometrial invasion. DNA content (AE), DNA malignancy grade (DNA-MG) and 5c exceeding rate were statistically significant in relation to the clinical course of the disease and the histological grade of differentiation. DNA parameters appear to be especially suitable for the objective assessment of malignancy.
