All enrolled patients presented in this report had sentinel lymph node examinations. Clinical outcomes of ipsilateral breast, axillary and combined regional (breast or axillary) recurrences were analyzed.Results: Median follow-up for all patients was 5 years (1– 8 years). No patient experienced either ipsilateral breast or axillary recurrence.Conclusion: There has been scarce information/reporting of the treatment of patients with cytokeratin positive individual tumor cells N0(i+) with APBI. The authors have presented data which suggest that the successful outcomes of these patients might warrant further study.Keywords: breast sentinel nodes, breast conservation therapy
