ABSTRACT

Demostrar que existe un grupo de pacientes estadios patológicos N0 que presentan metástasis en el estudio del ganglio centinela no diagnosticados por métodos de rutina. El estudio del análisis molecular nos informa o no sobre el pronóstico, y podría considerarse como factor independiente. Se observó una relación agrupando los casos de mayor riesgo conocido, detectándose una población de bajo riesgo en la que se obviaría la quimioterapia. Observamos, que si agrupamos las pacientes con Ki-67 mayor de 5 por ciento, la mayoría de los casos en las que se observaron micro metástasis estaban en este grupo; aceptamos una relación entre los dos factores pronóstico. Algo similar sucede con pacientes grado II y III; la relación con la existencia de micrometástasis es evidente, pudiendo aceptarse que existe un grupo de carcinomas de mama de menor agresividad; se plantea que estas pacientes no reciban tratamiento adyuvante, y no planificar tratamientos quirúrgicos agresivos.


Demonstrated that exist a group of patients with pathological stage No who present metastases in the study of sentinel nodule no diagnostic for routine method. The study of molecular analysis inform or not about the prognosis and be considered a prognosis independent factor. We observed a relation between the mayor risk known cases and detected a low risk population in which obviated the chemotherapy. We observed that grouped patients with Ki-67 raised of 5 % the majority of the cases in which observed micro metastases were in these group; we accepted a relationship between this two prognosis factors. Some similar occur with patient’s grade II and grade III; the relation with the existence of micro metastases is evident, and we accepted that exist a group of breast carcinoma of less aggressive; for these reason we planted that these patient does not receive adjuvant treatment, and no planned surgical aggressive treatment.
