Relación entre la expresión del her-2/ neu y el status nodal axilar en cáncer de mama

Abstract

Se realizó estudio descriptivo, comparativo de 74 casos de pacientes femeninas con diagnóstico histopatológico de adenocarcinoma de mama. A los pacientes se les practicó exceresis ganglionar, procesándose inicialmente con técnicas histoquímicas convencionales y posteriormente con técnicas inmunohistoquimicas utilizando el inmunomarcador HER-2/neu. Los resultados evidenciaron que el tipo histológico más frecuentemente diagnosticado fue el adenocarcinoma ductal infiltrante sin otra especificación (ADC Ductal SOE), en 65 casos (87,83 %), seguidos del ADC Ductal+ Comedocarcinoma, en ocho casos (10,81 %) y ADC Ductal + carcinoma medular en un caso (1,35%). Siendo el grupo etario más afectado el de las mujeres post menopáusicas de 50 años o más con un total de 34 casos (45,94%). Los ganglios linfáticos se encontraron afectados en 13 de las pacientes (17,56%), seis de las cuales presentaban un grado histológico II (46,15%) y siete un grado histológico III (53,85%).Así mismo, el comportamiento del inmunomarcador se manifestó positivamente en un 21,26% y negativo en un 78,38% con p≤ 0,05.Se concluye que los carcinomas de alta malignidad y estadios avanzados reprimen la expresión del HER-2/neu en un alto porcentaje la presencia de positividad para el mismo empobrece el pronosticó. De este modo el conocimiento del tipo y grado histológico del tumor, la afección ganglionar y el uso de inmunomarcadores de proliferación tumoral, utilizados en conjunto constituyen una herramienta útil en la evaluación de estas pacientes, lo que ofrecería así mejor opción para tratamiento adecuado a casos particulares en un estadio más temprano de la enfermedad.
