Validación y correlación de la tomosíntesis para el diagnóstico de lesiones sospechosas de cáncer de mama en mujeres. Sociedad de lucha contra el cáncer. Cuenca, 2018 - 2019

Abstract

Background: The "Gold standard" for breast pathology is digital mammography, it identifies different types of breast cancers before they have a clinical presentation and thus increase overall survival. Due to its excessive false positive results, it was necessary to implement new diagnostic techniques for the determination of pathology. Objective: To determine the validity and diagnostic correlation of tomosynthesis vs. histopathology in women with suspicious breast cancer lesions. SOLCA- Cuenca 2018 - 2019. Methodology: Validation diagnostic test study that will compare tomosynthesis in lesions suspected of breast pathology with the histopathological result. The universe was made up of 306 women. The sample size will be calculated using the Epidat 3.6 program, with the following criteria: 90% sensitivity, 79% specificity prevalence of the presence of breast cancer 29%, 5% precision, 95% confidence level. Results: tomosynthesis presented a sensitivity of 79.62% and a specificity of 7.58%, indicating that this is the probability that the test will identify the person who is sick as not sick. Conclusions: It was determined that tomosynthesis is a test with little agreement between the result and the histopathological diagnosis.
