title: DNA content as a prognostic factor in endometrial carcinoma.
abstract: Two hundred thirty-three cases of endometrial carcinoma were analyzed for DNA content using flow cytometry of cell nuclei extracted from archival paraffin blocks. The median follow-up time for the cases was 8.7 years. Aneuploidy, present in 18% of tumors overall, was associated with adverse histologic type, high grade, and depth of invasion in the uterus. Aneuploidy was not detected in low-grade carcinomas. A DNA index greater than 1.5 strongly predicted death from disease. For endometrial adenocarcinoma and papillary serous carcinoma, this finding appeared independent of stage or tumor grade. The percentage of cells in S phase or G2 + M of the cell cycle did not predict clinical outcome in diploid tumors. Application of DNA analysis to low-stage endometrial cancers of high grade or of papillary serous type may be useful for selecting a subgroup of patients for adjuvant therapy.
