Cáncer de mama: hallazgos sospechosos en mastografía asociados al resultado histopatológico.

Background: Breast cancer occupies first place in mortality by neoplasms in women in Mexico; mammography screening (MS) interpreted by BI-RADS (Breast Imaging-Reporting and Data System), allows suspicion of malignancy, which will be confirmed when having the histopathological result (HPR). Objective: To evaluate whether suspicious findings for breast cancer in MS are associated with malignant HPR in women aged = 40 years. Material and methods: Observational, analytical, crosssectional, prolective study. Patients aged = 40 years, with MS with BI-RADS 4a, 4b, 4c and 5, and RHP of sample obtained by Trucut, excisional or ultrasound guided wire biopsy. Sociodemographic, anthropometric, clinical variables, BI-RADS classification and HPR variables were recorded. Results: 148 patients were included, median age 53 years; these were stratified into BI-RADS 4a, BI-RADS 4b, BIRADS 4c and BI-RADS 5. Suspicious findings of malignancy due to MS were associated with HPR. MS BI-RADS 4c, palpable lesion and late menopause were identified as risk factors for malignant HPR; as well as MS BI-RADS 5 and palpable lesión. Conclusion: MS with suspicious findings of malignancy is associated with the malignant HPR obtained by biopsy. [ABSTRACT FROM AUTHOR]
