DNA ploidy, morphometry, and nuclear grade as prognostic factors in endometrial carcinoma.
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 on the 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 tumor-related 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.
