Abstract
had NSLN metastasis, while 14 patients were found to have ITC in SLN; none of them had NSLN metastasis. Multivariate analysis found that the number of SLN harboring micrometastasis is the only independent risk factor for NSLN metastasis in patients with micrometastasis (p-value = 0.008). On the contrary; Tumor size, grade and biology were not associated with NSLN metastasis. 5-year DFS in patients withmacrometastasis in SLNwas 94.2%, while that in patients with micrometastasis and ITC was 100% (P-value <0.001). Conclusion: NSLN metastasis in those who only have micrometastasis and ITC is rare, 5-year DFS is significantly better in this group of patients as well. It is therefore a routine practice in our unit to omit AD in patients with micrometastasis and ITC on SLN. Disclosure of Interest: No significant relationships.
