Flow cytometric analysis of endometrial stromal sarcoma.
Twenty-two endometrial stromal sarcomas were studied by flow cytometric analysis and the results were correlated with surgical stage, nuclear grade, mitotic index, and recurrence. Ploidy determination was not helpful in predicting recurrence in patients with Stage I disease because all 14 were diploid. Only 2 of the 22 tumors were aneuploid; both were high-stage neoplasms. Cell proliferation (%S or %S + %G2/M) did not significantly correlate with vascular invasion, nuclear grade, mitotic index, or surgical stage. Of the 13 Stage I neoplasms with follow-up data, three recurred. The mean proliferation index (%S + %G2/M) of those that recurred was 12.81 +/- 0.47, which did not differ from those that did not recur (mean 12.25 +/- 4.11).
