Background: Axillary lymph node dissection plays an important role in breast cancer management in terms of staging, prediction of prognosis, determination of adjuvant therapy, and local control of the primary tumor. The objective of this study was to evaluate the axillary lymph node involvement in multicentric breast tumors and breast tumors with nipple involvement in comparison with unifocal tumors. Patients and Methods: We reviewed the records of 267 patients with stage I or IIA disease. The rates of axillary lymph node metastasis (ALNM) in patients with unifocal tumors, multicentric tumors, or nipple involvement were compared. Results: 209 (78%) patients had unifocal tumors, 24 (8%) had multicentric tumors, and 34 (12%) had nipple involvement. The incidence of ALNM was 9.76% in patients with unifocal tumors, 24.84% in patients with multicentric tumors, and 36.71% in patients with nipple involvement. Hence, the incidence of ALNM was significantly higher in patients with nipple involvement or multicentric tumors than in patients with unifocal tumors. Conclusion: Our data suggest that compared to unifocal tumors, breast tumors with nipple involvement or multiple foci show a significantly higher incidence of ALNM which is a predictor of a poor prognosis. © 2012 S.
