Abstract
BACKGROUND: The aim of the present study was to identify the clinicopathological factors affecting locoregional recurrence (LRR) in patients with clinical stage IIIB noninflammatory breast cancer (NIBC). METHODS: The records of 120 stage IIIB NIBC patients treated with neoadjuvant chemotherapy (NAC) and then modified radical mastectomy followed by radiotherapy were evaluated. In this retrospective cohort, the effects of age, menopausal status, clinical tumor size, clinical response to NAC, pathological axillary status, number of positive axillary lymph nodes, pathological response to NAC, grade, lymphovascular invasion, estrogen receptor status, progesterone receptor status, Her-2-neu status, and p53 status on LRR were evaluated by univariate and multivariate analyses. RESULTS: The clinical response rate of 120 patients was 79.2% (17.5% complete and 61.7% partial), with a complete pathological response rate of 12.5%. The median follow-up was 28 months (range: 10-74 months). The LRR rate was 13.3%. Based on the univariate analysis, the clinical tumor size, clinical response rate, pathological axillary status, four or more positive axillary lymph nodes, lymphovascular invasion, and estrogen receptor status were factors that significantly affected LRR. In the multivariate analysis, however, only the clinical response rate and the number of positive axillary lymph nodes were found to be statistically significant independent factors. CONCLUSIONS: Effective local control of disease can be achieved in patients with stage IIIB NIBC using a combination of NAC, surgery, and radiotherapy. However, a worse clinical response after chemotherapy and four or more positive axillary lymph nodes affect LRR negatively in these patients.
