Purpose: to perform a census about the frequency of endometrial adenocarcinoma of women submitted to diagnostic hysteroscopy in five Brazilian hysteroscopic centers in São Paulo, Rio de Janeiro, Salvador, Caxias do Sul and Porto Alegre. Methods: information was collected from standard questionnaires about the presence of endometrial adenocarcinoma, hysteroscopic staging and histologic type, in pre- and postmenopausal women. Results: among 6,466 hysteroscopic procedures, endometrial adenocarcinoma was present in 92 patients (1.4%), confirmed by histology in 79 (1.2%) cases. For the hysteroscopic diagnosis of endometrial adenocarcinoma confirmed by histology, a sensitivity of 85.9%, specificity of 100%, positive predictive value of 100% and negative predictive value of 98.6% were obtained. In the premenopausal group, among 3,845 hysteroscopic exams, endometrial cancer was present in 83 (3.2%) and confirmed by histology in 71 cases (2.7%). Conclusions: this study points out the importance of epidemiological methods in the diagnostic and prevention programs of endometrial cancer, specially in postmenopause, revealing the need for further epidemiological studies on endometrial adenocarcinoma diagnostis and prevention programs.
