Correlación entre la biopsia por punción por aspiración con aguja fina y el diagnóstico histopatológico definitivo en nódulos mamarios, en el Instituto de Cáncer SOLCA Cuenca 2015-2017

Abstract

Background: Diagnosis of breast tumor is a challenge not only for general doctors but also for specialists. The fine needle aspiration cytology (FNAC) is an easy to perform procedure that consists of cell aspiration to use in a cytological study. FNAC sensibility is 80% to 97% with a specificity of 78% to 98% (1).

Objective: To evaluate the correlation between fine needle aspiration cytology (FNAC) and definitive histopathological diagnostic in breast nodules performed at Instituto de Cáncer SOLCA- Cuenca between 2015 and 2017.

Method and Materials: A descriptive study. The study universe was comprised for 229 clinical records from patients to whom a histopathological diagnostic was performed following a FNAC procedure. Statistical analyses will be done using SPSS v19.0 for Windows.

Results: A total of 229 clinical records with breast nodules. The patients’ average age was 49.53 years. The breast nodules are predominant in external upper quadrant (53.3%) being present more frequently (58.5%) in the breast left side. According to histopathological study, the 54.1% correspond to non-proliferative lesions followed by a malign condition in a 30.1%, obtaining a sensibility and specificity of the fine needle aspiration cytology (FNAC) of 46.88% and 95.15% respectively. Conclusions: Analyzed indicators allowed to establish that FNAC test can be used as a rapid and low-cost diagnostic method, after which it is necessary to accompany the results of the histological examination
