RESUMEN

Introducción:

el cáncer de mama es el más frecuente en las mujeres, se han hecho múltiples esfuerzos para clasificarlo con base en su perfil genético y el perfil de tinción de inmunohistoquímica. El cáncer de mama triple negativo se define por su falta de expresión a receptores de estrógeno, receptores de progesterona y receptor del factor de crecimiento epidérmico humano 2. Representa 15% de todos los cánceres de mama y son más frecuentes en mujeres premenopáusicas afroamericanas.

Objetivo:

establecer la prevalencia y describir las características clínico-patológicas de las pacientes con Cáncer de Mama triple-negativo que fueron operadas en el servicio de Ginecología y Obstetricia del HCAM en el año 2012. Materiales y

métodos:

se realizó un estudio descriptivo de corte transversal, en mujeres con diagnóstico histológico confirmado de cancer de mama. Se excluyó a las pacientes cuyos bloques de parafina no se conservaron, o a quienes no se les pudieron realizar todos los marcadores inmunohistoquímicos requeridos por el estudio.

Resultados:

un total de 159 casos de cáncer de mama invasor tratados quirúrgicamente en el servicio en el 2012, 17 fueron identificados como tumores triple negativos (RE negativo, RP negativo, HER-2 negativo).
ABSTRACT

Introduction:

breast cancer is the most frequent cancer in women; many efforts have been done to classify this cancer based on genetic and immunohistochemical staining profile. Triple-negative breast cancer is defined by a lack of expression of estrogen and progesterone receptor as well as human epidermal growth factor receptor 2. It represents 15% of all types of breast cancer and arises more frequently in premenopausal Afro-American women.

Objective:

to establish the prevalence and describe the clinic pathologic features of patients with triple-negative breast cancer who were operated in the Obstetrics and Gynecology Ward of the HCAM in 2012. Materials and

methods:

this was a descriptive cross-sectional study in women with histologically confirmed breast cancer. We excluded patients whose paraffin blocks were not kept or were not able to perform all required immunohistochemical markers for the study.

Results:

a total of 159 cases of invasive breast cancer treated surgically in service in 2012, 17 were identified as triple negative tumors (ER negative, PR negative, HER-2 negative).
