Evaluación endometrial vía histeroscopia en pacientes con cáncer de mama – receptores hormonales positivos, tratadas con hormonoterapia

Objective: To know via hysteroscopy the endometrial pathology associated with the use of hormone therapy in patients with breast cancer. Methods: Research design: non-experimental, longitudinal, trend; based on patients who come randomly, from January to July 2014, to the consultation of Los Andes University Hospital. Results: The mean age of the patients was 55.3 years, mean time of menopause 8.03 years; 8 (26.6%) patients had associated chronic arterial hypertension and diabetes mellitus II, and 10% of the patients had arterial hypertension. The most common endometrial alterations were: 46.7 % endometrial polyps, 13.3 % simple hyperplasia without atypia, 6.6 % leiomyomas. Among 5 (16.6%) users of exemestane (all with normal ultrasound), 3 (10%) had endometrial polyps and 2 (6.7%) negative biopsies. Among the 23 (76.7%) patients taking tamoxifen, 9 (30%) had thickened endometrium, 12 (40%) normal ultrasound and 2 (6.7%) other findings; 10 (33.3 %) had polyps (6 with normal ultrasound and 4 with endometrial thickening) and 3 endometrial hyperplasia (all with thickened endometrium). Two patients receiving both treatments, one had hyperplasia and one had polyps (both with thickened endometrium). The population studies in 60% were luminal B breast cancer; 1 (3.3 %) patient had a vagal reflex as a complication of the procedure. Conclusion: Histeroscopic findings most often diagnosed were endometrial polyps, simple hyperplasia without atypia and submucosal myomas.
