Abstract
Purpose
This study aimed to analyze the association between the primary tumor site and clinicopathological characteristics and survival prognosis of breast cancer (BC) patients using a large population database.
Methods
BC patients screened in the Surveillance, Epidemiology, and End Results (SEER) database were categorized into 6 groups based on primary sites. Descriptive statistics, Kaplan-Meier curves, Cox regression models, forest plots were used to assess the effect of primary sites on overall survival (OS) and breast cancer-specific survival (BCSS). Multivariate Cox proportional analyses were conducted to calculate hazard ratios (HRs) and adjusted subgroups’ hazard ratios (AHRs). Nomograms were utilized to predict OS and BCSS.
Results
Among 193,043 BC patients, the highest incidence was found in the upper outer quadrant (52.60%). Central portion patients are associated with more clinical features indicating a poor prognosis, and had worse OS and BCSS than other sites. Univariate and multifactorial Cox analyses showed associations between OS/BCSS and various factors. Subgroup analyses revealed differences in OS and BCSS between central portion and upper outer quadrant varied among age, T and N stage. The nomogram was established to predict the survival of central portion BC patients.
Conclusions
Primary tumor site is associated with clinicopathological features and prognosis of BC, may be influenced by age at diagnosis and T and N stage. Central portion BC patients have worse prognosis due to older age at diagnosis, higher T stage and higher likelihood of lymph node metastasis. Early diagnosis and treatment may help to improve survival of central portion BC.
本研究旨在利用大型人口数据库分析乳腺癌（BC）患者的原发肿瘤部位与临床病理特征和生存预后之间的关系。在监测、流行病学和最终结果（SEER）数据库中筛查出的乳腺癌患者根据原发部位分为 6 组。采用描述性统计、卡普兰-梅耶曲线、Cox回归模型和森林图来评估原发部位对总生存期（OS）和乳腺癌特异性生存期（BCSS）的影响。采用多变量考克斯比例分析法计算危险比（HRs）和调整亚组危险比（AHRs）。采用提名图预测OS和BCSS。在 193 043 名 BC 患者中，外上象限的发病率最高（52.60%）。与其他部位相比，中央部位患者具有更多预后不良的临床特征，其OS和BCSS也更差。单变量和多因素Cox分析显示，OS/BCSS与各种因素有关。亚组分析显示，中央部分和外上象限的OS和BCSS因年龄、T期和N期而异。建立了预测中央型 BC 患者生存期的提名图。原发肿瘤部位与BC的临床病理特征和预后有关，可能受诊断时的年龄、T期和N期的影响。中央型 BC 患者的预后较差，原因是诊断时年龄较大、T 分期较高以及淋巴结转移的可能性较高。早期诊断和治疗可能有助于提高中央型 BC 的生存率。
