Objetivo:
Conocer la concordancia entre imagen y patología de biopsias realizadas a lesiones mamarias.
MéTodo:
Estudio retrospectivo y comparativo en tres centros especializados en salud femenina (A, B y C). Se incluyeron pacientes con estudios de imagen sospechosos sometidas a biopsia entre enero de 2019 y julio de 2024. Se utilizó estadística descriptiva e inferencial, aplicando el coeficiente kappa de Cohen para evaluar la concordancia entre imagen y patología.
Resultados:
Se incluyeron 434 pacientes (248 en A, 85 en B y 101 en C). La concordancia global fue del 43%, con variaciones por institución: A 39%, B 62% y C 19%. La edad media fue de 34 años. El centro B destacó por uso de hormonoterapia (22%; p = 0.001). El centro C reportó menor escolaridad (4% analfabetismo) y el A mayor pobreza (88%). La biopsia escisional prevaleció en el centro C (73%).
Conclusiones:
La baja concordancia entre imagen y patología refleja disparidades institucionales. Se requiere mayor entrenamiento médico para optimizar la indicación y el análisis de biopsias mamarias.
Objective:
To assess the concordance between imaging findings and pathology results from biopsied breast lesions.
Method:
A retrospective, comparative study was conducted at three women’s health centers (A, B, and C). The study included patients with suspicious imaging findings who underwent breast biopsy between January 2019 and July 2024. Descriptive and inferential statistics were applied, and Cohen’s kappa coefficient was used to evaluate imaging-pathology concordance.
Results:
A total of 434 patients were included (248 from A, 85 from B, and 101 from C). Overall concordance between imaging and pathology was 43%, with institutional variations: 39% at A, 62% at B, and 19% at C. The mean patient age was 34 years. Center B had the highest use of hormone therapy (22%; p = 0.001). Center A reported the lowest educational level (4% illiteracy), while A had the highest rate of poverty among its patients (88%). Excisional biopsy was the predominant technique at center C (73%).
Conclusions:
The low imaging-pathology concordance observed reflects significant institutional disparities. These findings highlight the need for improved medical training to enhance the appropriate indication and interpretation of breast biopsies.
