Abstract

OBJECTIVES: Surgical management of the axilla with neoadjuvant treatment has been a significant research focus over the past decade, resulting in numerous publications. The trends in surgical choices based on lymph node status and survival outcomes in large populations were previously unclear. METHODS: Breast cancer patients who underwent neoadjuvant therapy were identified from the Surveillance, Epidemiology, and End Results (SEER) database from 2010 to 2021 and categorized into 2 cohorts: LN- (no lymph node metastasis) and LNm (1-2 sentinel node metastases). We analyzed the trends in surgical axillary staging and compared the 10-year overall survival between sentinel lymph node biopsy (SLNB) and axillary lymph node dissection (ALND). RESULTS: Among 26,320 patients, 18,548 were in the LN- cohort (16,607 with SLNB and 1,941 with ALND) and 7,772 were in the LNm cohort (3,601 with SLNB and 4,171 with ALND). The proportion of patients undergoing SLNB increased from 76.4% in 2010 to 93.8% in 2021 in the LN- cohort and doubled from 25.2% in 2010 to 55.0% in 2021 in the LNm cohort. ALND was identified as a favorable factor over SLNB in the LNm cohort (hazard ratio [HR] 0.84; 95% CI, 0.73-0.96; P = .014). CONCLUSION: Omission of ALND for patients with 1 to 2 node metastases after neoadjuvant therapy has doubled since 2010. SLNB is an efficient and safe approach of surgical axillary staging for the LN- cohort but not for patients with residual axillary cancer, even with low-volume disease.

摘要

目的:在过去十年中,新辅助治疗下腋窝的外科治疗一直是重要的研究重点,产生了大量的出版物。此前,基于淋巴结状态和大样本生存结果的手术选择趋势尚不清楚。 方法:从2010年至2021年的监测、流行病学和最终结果(SEER)数据库中识别接受新辅助治疗的乳腺癌患者,并分为2个队列:LN-(无淋巴结转移)和LNm(1-2个前哨淋巴结转移)。我们分析了手术腋窝分期的趋势,并比较了前哨淋巴结活检(SLNB)和腋窝淋巴结清扫(ALND)之间的10年总生存率。 结果:在26320例患者中,18548例在LN-队列(16607例行SLNB,1941例行ALND),7772例在LNm队列(3601例行SLNB,4171例行ALND)。LN-队列中接受SLNB的患者比例从2010年的76.4%增加到2021年的93.8%,LNm队列中从2010年的25.2%增加了一倍至2021年的55.0%。在LNm队列中,ALND被确定为优于SLNB的有利因素(风险比[HR]0.84;95%CI,0.73-0.96;P = 0.014)。 结论:自2010年以来,新辅助治疗后有1至两个淋巴结转移的患者省略ALND的情况增加了一倍。SLNB是LN-队列手术腋窝分期的一种有效且安全的方法,但对于残留腋窝癌患者,即使疾病量少也不适用。
