The secondary objective was to observe any incidence of ipsilateral breast failure.Patients and Methods: Between March 2004 and April 2016, a total of 747 patients were enrolled in one of two APBI (Accelerated Partial Breast Irradiation) breast protocols (Phase II NCT01185145 and Phase III NCT01185132). Nineteen patients with N0(i+) disease were treated between February 2005 and December 2015. Patient eligibility included a primary invasive or DCIS tumor size < 3 cm, N0(i+) disease, and margin width of > 2 mm. 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 therapySmith JLeonard CCarter DLTole SDove Medical Pressarticlebreast sentinel nodesbreast conservation therapyNeoplasms.
