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本数据集包含与论文《淋巴结阴性乳腺癌的生物学特征及长期转归》相关的原始数据。由于淋巴结阴性乳腺癌（node-negative breast cancer, BC）的复发风险存在显著异质性，本研究对1276例该疾病患者的预后及与复发风险升高相关的影响因素展开了评估。整体而言，在淋巴结阴性乳腺癌中，患者年龄、激素受体状态、肿瘤大小以及Ki67均为预后相关因素。三阴性乳腺癌（triple-negative breast cancer）亚型与人表皮生长因子受体2阳性（human epidermal growth factor receptor 2-positive）亚型相比，并未呈现更差的预后，但相较于腔面型乳腺癌（luminal-like breast cancer），其总生存期更短。研究背景：鉴于淋巴结阴性乳腺癌的复发风险存在差异，本研究评估了该类患者的预后情况以及与复发风险升高相关的影响因素。患者与方法：本研究对经证实为淋巴结阴性乳腺癌且具备至少5年随访资料的患者的临床病历资料进行了回顾性分析。
