Validación de la mamografía y ultrasonido para el diagnóstico de cáncer de mama

Abstract

Objective: To determine the validity of mammography and ultrasound for the diagnosis of breast cancer compared with the histopathological result in patients who attend the National Medical Center "November 20" during the years 2015 to 2019. Material and methods: A diagnostic test validation study was carried out, consisting of the patients categorized as BI-RADS 4 (A, B and C) and 5 in ultrasound and mammography compared with the result of the core biopsy histopathology as gold test, in the years 2015 to 2019. Results: 72.78% were between 35 and 64 years old. 51.54% were diagnosed with a malignant histopathological result, and 48.46% had benign results. 26.77% of category 4A presented malignancy in the histopathological result, 4B 46.27%, 4C 86.36% and 5 96.88%. Specificity and PPV for BI-RADS 4A (E: 45; 69%, PPV: 26.77%), 4B (E: 53.04%, PPV: 46.27%), 4C (E: 95.51%, PPV: 86.36%) and 5 (E: 99.25%, PPV: 96.88%). Conclusion: The application of the BI-RADS categories by mammography and ultrasound show high specificity and positive predictive value for the diagnosis of suspicious breast cancer lesions, increasing successively from 4A, 4B, 4C and 5.
