Identification of sentinel node (SN) involvement predictive factors, non-sentinel node involvement predictive factors, selective prognosis of each group of patients by study of breast surgery cases with sentinel node sampling. ⋯ First, 72.1% of T0 or T1 tumors, avoid adverse axillary dissection effects. Second, micrometastatic involvement predictive factors do not differ from macrometastatic ones and those of positive secondary axillary dissection among micrometastatic SN do not appear clearly : the risk of axillary recurrence is low: at the very most, it seems possible to propose a safe guideline, avoiding secondary axillary dissection only for selected group of lower risk patients: tumoral size < 10 mm, grade I, monocentric SN involvement. Third, it is not possible to differentiate a selective prognosis between negative, CTI, micrometastatic and macrometastatic SN subgroups probably because of a short follow-up. Fourth, teaching through companionship is fully valided by the secondary minimal rate of axillary recurrence.
