Abstract
In a retrospective analysis of 106 cases of endometrial carcinoma stages I-IV (FIGO), the prognostic value of DNA ploidy and nuclear morphometry of tumor cells was evaluated and compared with that of conventional clinical and histopathologic parameters. Paraffin-embedded tumor tissue from the original curettage specimens was used. A flow cytometric technique was employed to distinguish diploid from aneuploid tumors. It was not possible to estimate S-phase rates by this method. Eight different nucleus-related morphometric parameters were computed from representative tumor regions on the original slides. All histologic specimens were reviewed by one pathologist and graded according to FIGO; nuclear grade was determined separately. Tumor stage, depth of myometrial infiltration, and nuclear grade were the most important prognostic factors with regard to tumorrelated survival. DNA ploidy and nuclear morphometry did not add significant prognostic information that could be used to distinguish high-risk and low-risk populations with endometrial carcinomas. The simple nuclear grading system should be further evaluated in prospective studies and compared with DNA analysis and nuclear morphometry performed on fresh-frozen tissue.
