The Impact of Sentinel Lymph Node Biopsy on Female Patients With T3-4c Breast Cancer and 1-2 Positive Lymph Nodes: A Population-Based Cohort Study.
Clinical Breast Cancer 2023 November 18
PURPOSE: This study aimed to evaluate the efficacy of sentinel lymph node biopsy (SLNB) in patients diagnosed with cT3-4c breast cancer with no more than 2 positive sentinel lymph nodes.
METHODS: Using data from the Surveillance, Epidemiology, and End Results (SEER) database, this retrospective study identified patients diagnosed with T3-4c breast cancer between 2010 and 2015. These patients were then categorized into 2 groups: the SLNB group, which underwent examination of 1-5 regional lymph nodes and the axillary lymph node dissection (ALND) group, which underwent examination of ≥10 regional lymph nodes. Propensity score matching analysis was used to assess the efficacy of SLNB in cT3-4c patients.
RESULTS: A total of 1139 patients were included in the analysis, with 423 and 716 patients in the SLNB and ALND groups, respectively. The 10-year overall survival (OS) and breast cancer-specific survival (BCSS) rates in the SLNB group were 66.1% and 76.3%, respectively, compared with 66.0% and 73.8%, respectively. Statistical analysis revealed no significant differences between the 2 groups in terms of OS (HR = 1.00, 95% CI = 0.80-1.25, P = .997) and BCSS (HR = 1.08, 95% CI = 0.83-1.41, P = .551). Even after 1:1 propensity score matching, there were no significant differences in OS (HR = 0.87, 95% CI = 0.65-1.16, P = .341) and BCSS (HR = 0.82, 95% CI = 0.59-1.16, P = .266) between the 2 groups.
CONCLUSION: This study demonstrates that SLNB does not adversely affect the survival of cT3-4c breast cancer patients with 1-2 sentinel lymph node metastases.
