To define the prognostic significance of HER-2/neu and PTEN expression in patients with endometrioid (type I) endometrial cancer. %26lt;br%26gt;Seventy-seven patients with endometrioid endometrial carcinoma were included in the study, in a period between 1996 and 2009. Patients with coexisting malignancy and those having incomplete immunohistochemical data or clinical follow-up were excluded. Histological staging was defined according to the revised FIGO staging (2009). Clinico-pathologic and immunohistochemical characteristics were correlated in a multivariate Cox regression analysis with overall survival (OS), cancer-related survival (CRS) and disease-free survival (DFS). %26lt;br%26gt;Mean age of the patients was 62.7 years. The median follow-up was 67 months (9-124 months). HER-2/neu expression was detected in 18.2 % (n = 14), and PTEN expression in 72.7 % (n = 56) of our patients. Multivariate Cox regression analysis showed that patient%26apos;s age, FIGO staging and HER-2/neu expression were independent prognostic factors for OS, CRS and DFS. PTEN expression did not significantly affect survival outcomes of the present study. %26lt;br%26gt;HER-2/neu but not PTEN expression is an independent prognostic factor for type I endometrial carcinoma.
