This record contains raw data related to article “Biological Characteristics and Long-term Outcomes in Node-negative Breast Cancer"

Because the risk of relapse of node-negative breast cancer (BC) is largely varying, we evaluated the prognosis of a cohort of 1276 patients with this disease and the factors associated with increased risk of relapse. Overall, in nodenegative BC, age, hormonal receptor status, tumor size, and Ki67 were prognostic factors. The triple-negative BC subtype was not associated with a poorer prognosis compared with the human epidermal growth factor receptor 2-positive subtype, but showed a worse overall survival compared with luminal-like BC. Background: Because the risk of relapse of node-negative breast cancer (BC) is varying, we evaluated the prognosis of patients with this disease and the factors associated with increased risk of relapse. Patients and Methods: The clinical charts of patients with BC with evidence of negative nodes and with a potential 5-year follow-up were retrospectively reviewed
