Abstract

BACKGROUND: Contralateral axillary nodal metastases (CAM) is classified as stage IV disease, although many centers treat CAM with curative intent. We hypothesized that patients with CAM, treated with multimodality therapy, would have improved overall survival (OS) versus patients with distant metastatic disease (M1) and similar OS to those with locally advanced breast cancer (LABC). METHODS: Using the NCDB (2004-2016), we categorized adult patients with node-positive breast cancer into three study groups: LABC, CAM, and M1. Kaplan-Meier curves were used to visualize the unadjusted OS. Cox proportional hazards models were used to estimate the association of study group with OS. RESULTS: A total of 94,487 patients were identified: 122 with CAM, 12,325 with LABC, and 82,040 with M1 (median follow-up 63.6 months). LABC and CAM patients had similar histology and rates of chemotherapy and endocrine therapy receipt. However, the CAM group had significantly larger tumors, more estrogen-receptor expression, higher T-stage, and more mastectomies than the LABC group. Compared with M1 patients, CAM patients were more likely to have grade 3 and cT4 tumors. Patients with CAM and LABC had similar 5-year unadjusted OS and significantly improved OS vs M1 patients. After adjustment, LABC and CAM patients continued to have similar OS and better OS vs M1 patients. CONCLUSIONS: CAM patients who receive multi-modal therapy with curative intent may have OS more comparable to LABC patients than M1 patients. Out data support a reevaluation of whether CAM should remain classified as M1, as N3 may better reflect disease prognosis and treatment goals.

摘要

背景:对侧腋窝淋巴结转移(CAM)被归类为 IV 期疾病,尽管许多中心采用治愈性意图治疗 CAM。我们假设接受多模式治疗的 CAM 患者的总生存(OS)会得到改善,与远处转移性疾病(M1)患者相比,与局部晚期乳腺癌(LABC)患者的 OS 相似。

方法:使用 NCDB(2004-2016 年),我们将患有淋巴结阳性乳腺癌的成年患者分为三组研究组:LABC、CAM 和 M1。使用 Kaplan-Meier 曲线来可视化未调整的 OS。使用 Cox 比例风险模型来估计研究组与 OS 的关联。

结果:共确定了 94487 名患者:122 名患有 CAM,12325 名患有 LABC,82040 名患有 M1(中位随访 63.6 个月)。LABC 和 CAM 患者的组织学和化疗及内分泌治疗接受率相似。然而,CAM 组的肿瘤明显更大,雌激素受体表达更高,T 期更高,乳房切除术更多。与 M1 患者相比,CAM 患者更有可能出现 3 级和 cT4 肿瘤。与 M1 患者相比,CAM 患者和 LABC 患者的 5 年未调整 OS 相似,OS 显著改善。调整后,LABC 和 CAM 患者的 OS 继续与 M1 患者相似,并且优于 M1 患者。

结论:接受治愈性意图多模式治疗的 CAM 患者的 OS 可能与 LABC 患者比 M1 患者更相似。我们的数据支持重新评估 CAM 是否应继续归类为 M1,因为 N3 可能更好地反映疾病预后和治疗目标。
