Estudios mamográficos en un centro metropolitano de referencia en imágenes mamarias: Chile 2008-2018 ¿Vamos por el camino correcto?

Resumen

Background: Mammograms are one of the most effective preventive means for the early detection of breast cancer. Aim: To describe the features of patients and results of mammograms performed at a public imaging service of Metropolitan Santiago. Material and methods: We reviewed the reports of mammograms performed to 174017 women and 18 men, between 2008 and 2018 in an Imaging Center. BI-RADS classification was used in the reports. Results: Forty six percent of mammograms (75,781) were reported as BI-RADS 2. The higher proportion of BI-RADS 4 reports (674 reports) was observed in patients aged 40 to 49 years, corresponding to 30% of reports in this age range. Among patients aged 50 to 59 years there were 779 BI-RADS 4 reports (35%). BI-RADS 5 reports were more common among patients aged 50 to 59 years (50 reports, 30%) and among patients aged 70 years or more ( 83 reports, 28%). Conclusions: The greater proportion of BI-RADS 4 reports among patients aged 40 to 49 years should prompt a more aggressive search of breast cancer in this age range.
