ABSTRACT
<p><b>OBJECTIVE</b>To identify predictive markers of the long-term outcome for neo-adjuvant chemotherapy (NC) in locally advanced breast cancer (LABC) treated with intravenous vinorelbine (V) and epirubicin (E) combination regimen.</p><p><b>METHODS</b>One hundred and nineteen patients with LABC were treated from September 2001 to May 2006. All patients were diagnosed as invasive breast cancer by 14G core needle biopsy and treated with three cycles of VE regimen before the operation. The patients were subjected to surgery and subsequently were given other three cycles of VE or cyclophosphamide+epirubicin+fluorouracil (CEF) regimen according to the clinical responses. Local-regional radiotherapy was applied to all patients after the chemotherapy and followed by hormone-therapy according to hormone receptor status. The impact of clinical, pathological, and immunohistochemical features on disease free survival (DFS) and overall survival (OS) was evaluated.</p><p><b>RESULTS</b>All patients were evaluable for responses clinical complete response was documented in 27 patients (22.7%), 78 patients (65.5%) obtained partial clinical response. The pathological complete response was found in 22 cases (18.5%). Of the patients, 115 cases (96.6%) were followed-up for a median time of 63.4 months (range, 9-76 months), the 5-year DFS rate and OS rate was 58.7% and 71.3%, respectively. On multivariate analysis, high pre-Ki-67 (P=0.012) and post-Ki-67 expression (P=0.045), no pathological complete response after NC (P=0.034) were associated with the higher risk of disease relapse; high pre-Ki-67 (P=0.017) and post-Ki-67 expression (P=0.001), negative pre-ER (P=0.002) and no pathological complete response after NC (P=0.034) were associated with a shorter survival.</p><p><b>CONCLUSION</b>Pathological response in primary tumor, pre-Ki-67 and post-Ki-67 expression, pre-ER expression are important predictors of long-term outcome for LABC patients with three cycles of VE regimen before operation.</p>
