title: Treatment Outcome of Breast Cancer with Pathologically Proven Synchronous Ipsilateral Supraclavicular Lymph Node Metastases.
abstract: OBJECTIVE
  The aim of this study was to investigate the prognosis, patterns of failure, and prognostic factors for breast cancer patients with pathologically proven synchronous ipsilateral supraclavicular lymph node (ISCLN) metastases.
  
  
  METHODS
  We reviewed the records of breast cancer patients with pathologically proven ISCLN metastases. Local aggressive treatment was defined as treatment including surgery, axillary lymph node dissection (ALND), ISCLN excision, radiotherapy (RT), and chemotherapy.
  
  
  RESULTS
  A total of 111 patients were included. The 5-year overall survival (OS) and disease-free survival (DFS) rates were 64.2% and 56.2%, respectively. On univariate analysis, RT, ALND, trastuzumab treatment, hormone receptor (HR) status, and local aggressive treatment were identified as significant factors for OS. The 5-year OS for 73 patients who received local aggressive treatment was superior to that of 38 patients who received nonaggressive treatment (70.9% vs. 49.3%, p=0.036). Multivariate analysis showed that RT, HR status, and trastuzumab were significant variables for the 5-year OS and DFS.
  
  
  CONCLUSIONS
  Multimodality treatment with surgery, taxane-based chemotherapy, hormone therapy, and RT is strongly recommended for breast cancer patients with synchronous ISCLN metastases.
