Concomitant endometrial hyperplasia in patients with endometrial carcinoma.
OBJECTIVE
The aim of this study was to compare the histopathologic features and prognosis of patients with endometrial carcinoma with and without concomitant hyperplasia.


METHODS
Histologic slides of the surgical specimens of 214 consecutive patients who underwent surgery as primary treatment for endometrial carcinoma from 1985 through 1991 were reviewed.


RESULTS
Ninety-two of the 214 patients (43%) with endometrial carcinoma had concomitant endometrial hyperplasia. Patients with endometrial carcinoma with hyperplasia were significantly younger than those without hyperplasia (mean age 62 +/- 10 vs 65 +/- 9 years, P < 0.05). Carcinomas associated with hyperplasia were better differentiated and of lower surgical stage. By univariate analysis the frequency of recurrence was significantly lower (4% vs 17%, P < 0.004) and the estimated 5-year survival rate significantly higher (96% vs 85%, P < 0.01) in patients with endometrial carcinoma with concomitant hyperplasia. However, in multivariate analysis the presence of endometrial hyperplasia was not an independent prognostic factor and the 5-year survival rates of patients with or without hyperplasia did not differ significantly in any surgical stage.


CONCLUSIONS
The presence or absence of concomitant endometrial hyperplasia is strongly correlated with the surgical stage of endometrial carcinoma.
