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.
