The aim of this study was to compare well-differentiated (grade 1) and less-differentiated (grades 2 and 3) endometrial carcinoma, concerning clinical risk factors, presenting symptoms and operative findings. Seventy-one surgically staged endometrial carcinoma cases were reviewed and retrospectively divided according to tumor differentiation into two groups: grade 1 cases (Group I; n = 40) and grade 2 and 3 cases (Group II; n = 31). No difference was found between the two groups when comparing patient age, gravidity and parity, history of hypertension, diabetes or other malignancies, duration of menopause, number of patients receiving hormonal replacement therapy and histological type of tumor. There was also no difference in presenting symptoms or in duration of uterine bleeding up to the diagnosis of endometrial carcinoma. On the other hand, patients with well-differentiated tumors, as compared to patients with less-differentiated endometrial carcinoma, were significantly more obese (p < 0.02), had a smaller uterus (p < 0.01) and presented with less advanced stage disease (p < 0.0005). The fact that the age of the patients, as well as the duration of uterine bleeding before diagnosis, was similar in both groups may indicate that more advanced cases, as in group II, represent originally a more aggressive tumor rather than progression from a well-differentiated disease. This hypothesis needs further research.
