ABSTRACT: Background
We aim to assess the value of locoregional treatment (LRT) including breast-conserving surgery (BCS), mastectomy (MAST), and radiotherapy (RT) in patients with de novo stage IV breast cancer.Methods
Patients with de novo stage IV breast cancer were retrospectively identified from the Surveillance, Epidemiology, and End Results database between 2004 and 2014. Kaplan-Meier analysis, log-rank tests, propensity score matching (PSM), and the multivariate Cox proportional model were used for statistical analysis.Results
A total of 5798 patients were identified including 849 (14.6%), 763 (13.2%), 2338 (40.3%), and 1848 (31.9%) who received BCS alone, BCS+RT, MAST alone, and MAST+RT, respectively. The proportions of receiving BCS decreased from 35.9% in 2004 to 2
