Endometrioid endometrial carcinomas (EECs) are the most common malignancies of the uterus. Hormonal dependence of EEC, in relation to biomolecular mechanisms involved in tumor progression, such as angiogenesis and cell proliferation, are aspects that can contribute to improving the prognosis of patients. We analyzed the immunoexpression of markers addressed to steroid hormone receptors [estrogen receptor (ER), progesterone receptor (PR)], angiogenesis [cluster of differentiation (CD)105/endoglin] and cell proliferation (Ki-67) in 50 EECs related to the histopathological prognostic criteria of the lesions. In this study, the ER and PR scores were higher in low grade and early stages EEC, the statistical aspects being variable. The CD105 microvessel density and the Ki-67 proliferation index were superior in high grade and advanced stages EEC, the statistical aspects being significant or at the limit of significance. The ER/PR and CD105/Ki-67 immunomarker groups indicated a positive linear intragroup relation and a negative linear intergroup relation, suggesting the presence of synergistic and antagonistic molecular mechanisms of tumor endometrial control that can be used to stratify patients for targeted therapy.
