OBJECTIVE: It has been reported that endometrial carcinoma has two pathogenic types; one with and the other without endometrial hyperplasia. The present study was done to clarify whether this was true in our series of a large number of Japanese patients.
METHODS: Three hundred and twenty-eight patients with endometrial carcinoma were classified into two groups, one coexisting endometrial hyperplasia (group 1; 182 cases) and the other having normal endometrium without endometrial hyperplasia (group 2; 107 cases). The clinical and pathological observations of the two groups were compared.
RESULTS: The ages of the patients were significantly lower in group 1 (30-83; mean 50.7) than in group 2 (34-81; mean, 57.2). The incidence of the carcinoma with invasion limited to less than 1/3 of the myometrium, with surgical stage I, lower grade endometrioid type and higher levels of progesterone receptor, and without lymph node metastasis were significantly higher in group 1 than in group 2. The cumulative survival rate for stage I was also significantly higher in group 1 patients.
CONCLUSION: A significant difference was found between groups 1 and 2 in age distribution, degree of progress and pathological observations. Stage I patients in the former group had a better prognostic than the latter.
