Axillary lymph node removal in de novo metastatic breast cancer.

ABSTRACT:

Background

Several prospective studies have found that local surgical resection did not improve the survival of patients with de novo metastatic breast cancer (dnMBC). However, a significant portion of dnMBC patients still undergo local surgery, and the role of axillary lymph node dissection (ALND) in dnMBC patients remains unclear. This study aimed to investigate the effect of ALND in patients with dnMBC.

Methods

We included patients diagnosed with dnMBC between 2010 and 2020 using the data from the Surveillance, Epidemiology, and End Results program. The Chi-square test, binomial logistic regression, propensity score matching (PSM), Kaplan-Meier method, and multivariate Cox proportional models were employed for statistical analysis.
