Nuclear DNA content, proliferative activity, and p53 expression related to clinical and histopathologic features in endometrial carcinoma

Int J Gynecol Cancer. Jan-Feb 2002;12(1):110-8. doi: 10.1046/j.1525-1438.2002.01079.x.

Abstract

The purpose of this study was to evaluate the prognostic impact of image cytometry DNA ploidy, MIB-1, and p53 in relation to clinicopathologic variables in 376 consecutive patients with endometrial carcinoma stages I-IV. Following primary treatment 358 patients were considered tumor-free. Relapses and tumor-specific deaths of these patients were noted. Image cytometry DNA ploidy (n = 340) and expression of MIB-1 (n = 318) and p53 (n = 323) were studied. In univariate analysis, stage (P < 0.001), histopathologic subtype (P < 0.001), degree of differentiation (P < 0.001), HRT (P = 0.034), DNA ploidy (P < 0.001), and p53 (P < 0.001) were significant predictors of relapse. Patient age showed that the estimated mean risk of relapse increases with nearly 64% per decade in life (P 0.003), and the MIB-1 expression with 21% per 10-unit increment (P 0.004). In multivariate analysis, degree of differentiation, MIB-1, and p53 lost their prognostic capability. However, after stage and histopathologic subtype, image cytometry DNA ploidy was the strongest predictor of outcome and was of value in predicting the risk for relapse. The combination of DNA ploidy, MIB-1, and p53 expression was an even stronger predictor of relapse-free survival than the individual prognostic factors.
