Breast-conserving Surgery Rates in Breast Cancer Patients With Different Molecular Subtypes: An Observational Study Based on Surveillance, Epidemiology, and End Results (SEER) Database.

ABSTRACT: This study used the Surveillance, Epidemiology, and End Results database to compare breast-conserving surgery (BCS) rates across patients with different molecular subtypes.We identified female breast cancer patients who were diagnosed between 2010 and 2012 using the Surveillance, Epidemiology, and End Results database. Patients without available critical clinicopathological information were excluded. The chi-square test and logistic regression analysis were used to investigate factors associated with BCS.This study identified 85,415 T1-2N0-3M0 breast cancer patients. Among the patients with HR+/HER2-, HR+/HER2+, HR-/HER2+, and HR-/HER2- diseases, 63.5% (38,823/61,142), 51.2% (4850/9473), 43.2% (1740/4030), and 55.7% (6000/10,770), respectively, received BCS (P < 0.01). Patients with HR-/HE
