Abstract【Objective】To investigate the 5-year survival rate and prognostic factors of breast cancer patients with ipsilateral supraclavicular lymph node metastasis. 【Methods】A total of 110 locally advanced triple negative invasive breast cancer (TNBC) with ipsilateral supraclavicular lymph node metastasis but no distant metastasis admitted to our hospital were enrolled in the study. The patients all received 4-6 cycles of neoadjuvant chemotherapy, followed by surgery and radiotherapy. Patients' 5-year survival rates were recorded and factors affecting disease-free survival (DFS) and overall survival (OS) were analyzed. 【Results】 The follow-up time was 54-72 months. The median follow-up time was 65.2 months. A total of 49 deaths occurred. The 5-year survival rate was 55.45% (61/110) with median survival time 31.9 months. The 5-year survival rates of patients with negative supraclavicular lymph node metastasis and pathological complete remission (pCR) after surgery was 73.68% (28/38) and 81.82% (18/22), which were higher than those of supraclavicular lymph node-positive metastasis 52.78% (38/72) and non-pCR patients 54.55% (48/88), (P<0.05). Kaplan-Meier method and Log-rank test showed that the size of supraclavicular lymph nodes before chemotherapy, Ki-67 level in pre-chemotherapy breast tissue, supraclavicular lymph node status after chemotherapy, axillary lymph node status, subclavian lymph node status, pCR and ipsilateral supraclavicular lymph node status after chemotherapy were correlated with DFS (P<0.05); and age, Ki-67 staining in pre-chemotherapy breast cancer, supraclavicular lymph node status, axillary lymph node status, and pCR were associated with OS as well (P<0.05). Cox multivariate analysis showed that the metastatic status of supraclavicular lymph node, axillary lymph node and subclavian lymph node, and pCR were independent influencing factors of DFS (P<0.05) after chemotherapy. Age, supraclavicular lymph node status after chemotherapy and pCR were independent factors of OS (P<0.05). 【Conclusion】The 5-year survival rate of triple-negative breast cancer with ipsilateral supraclavicular lymph node metastasis is improved after comprehensive treatment. The status of supraclavicular lymph node and pCR after chemotherapy are important factors influencing prognosis.
