    Abstract:
    Feulgen-DNA and nuclear light green-protein measurements have been performed in isolated nuclei of normal (nonmalignant) and malignant human endometrial homogenates. The DNA content of the G0/G1 fraction of malignant endometrium showed much overlap with that of normal endometrium, or was slightly increased. Two of the 18 carcinomas were clearly aneuploid. No correlation was found between the histological grade and the DNA content. The tumors of clinical stage II and higher all had a higher DNA content than that of normal endometrium. The percentage of cells present in the proliferative fraction was higher in proliferative endometrium than in secretory and post-menopausal atrophic endometrium. For malignant endometrium, percentages were found comparable to that of normal endometrium or higher. No correlation was found with the histological grade. Tumors of stage II and higher had intermediate values compared to those of carcinomas below stage II. The nuclear protein/DNA ratio of malignant endometrium completely overlapped that of normal endometrium. However, for post-menopausal women, most values of the carcinomas exceeded that of normal, atrophic, endometrium. Within the tumor population, no correlation was found with the histological grade. Higher values were found with tumors of clinical stage II and higher.
