Abstract

Flow cytometric DNA content and proliferative kinetic markers, S-phase fraction (SPF) and thymidine labeling index (TLI), were evaluated in 68 patients with endometrial carcinoma. A high rate of aneuploid tumors was detected (48.4%); median values of SPF and TLI were 6.4 and 6.2, respectively. No significant relationship emerged between ploidy status and proliferative markers in respect to clinical and pathological variables. Aneuploid tumors had a higher recurrence rate than diploid tumors (21.8% vs 9.6%). but the difference was not statistically significant. According to the median value of both kinetic markers, the study population was divided into low and high-risk, where DFS was 100% and 71.4% respectively (p =0.05). Furthermore, high-TLI tumors (>6.2) had a significantly worse DFS (75.4%) than low-TLI (100%) only among patients assigned to Stage I of the disease, regardless of other pathological variables. At multivariate analysis myometrial invasion resulted as an independent and significant factor. Flow cytometric ploidy analysis was useless as a predictive biological parameter and did not add any further prognostic information to the pathologic variables. SPF and TLI values could indicate a subset of women with unexpected poor outcome in a group of patients generally considered at low-risk, i.e. Stage I. If further investigation confirms these data, it could prove useful for therapeutic planning in endometrial cancer patients. At the present time, pathological and clinical factors are still the most reliable predictive parameters.
