Introducción.- El carcinoma ductal infiltrante, sin patrón específico, representa el tipo histológico más frecuente de los tumores malignos mamarios y presenta un comportamiento biológico diverso. La variable evolución de la enfermedad ha estimulado a los investigadores a definir los parámetros que permitan delimitar subgrupos de pacientes con el objetivo de optimizar la terapéutica. Los factores pronósticos de primera generación han logrado tener resultados satisfactorios. Las técnicas inmunohistoquímicas han permitido señalizar nuevas rutas terapéuticas con resultados poco contrastados. La valoración comparativa de ambos parámetros está escasamente reflejada en la literatura. Palabras Claves: Carcinoma ductal infiltrante, HER2/neu, factores pronósticos. |

Abstract: | |
Introduction: Invasive ductal carcinoma is the most frequent malignant tumor of the breast and its behavior is heterogeneous. Different therapeutic groups have been established depending on the morphologic features. Immunohistochemistry has opned new therapeutic optiions but the results are not contasted enough. Material and methds: We have correlated tumor size, combined histological grade, axilar ganglionar status and p53, MIB1, HER2/neu and expression of estrogens receptors in 107 patients with invasive ductal carcionoma of the breast. Results: There is statistic correlation between expression of estrogens receptors and nuclear grade, mitotic index, tubular differentation, histological grade, axiliar ganglion status and metastatic lymphatic ganglion group. There is not correlation with the tumor size. There are not significant alterations in p53 expression when it is correlated with the different morphologic parameters, only with tubular differentiation. El MIB1 expession correlates with nuclear grades, mitotic index. HER2/neu (+), especially in the group>4. Conclusions: The tumors receptors (+) have statitic carrelation with histological high grade and axilar ganglion status (+). The Tumors Her/2neu (+) have statistic correlation with histological high grade and axilar ganglion status (+), especially in the group >4. Key words: Invasive ductal carcinoma, HER2/neu, prognostic factors. |
