Abstract

Background: For patients with de novo stage IV breast cancer (BC), the conditions under which the primary tumor resection (PTR) may offer benefit remain unclear.

Methods: The SEER database provides treatment data for patients with de novo stage IV BC. We screened cases of metastatic BC diagnosed from 2010 to 2015, with primary endpoints of overall survival (OS) and cancer-specific survival (CSS).

Results: 9252 patients with stage IV de novo BC were enrolled. For OS, median survival time (MST) was 38 months with systematic treatment (ST) compared to 52 months with ST plus PTR (p < 0.001). For CSS, MST was 38 months for ST versus 54 months for ST plus PTR (p < 0.001). The results of the Cox proportional hazards regression analysis regarding PTR, for OS: bone metastasis (aHR 0.664, 95%CI 0.583-0.756, p < 0.001); liver-lung metastasis (aHR 0.528, 95%CI 0.327-0.853, p = 0.009). For CSS: bone metastasis (aHR 0.655, 95%CI 0.571-0.751, p < 0.001); liver-lung metastasis (aHR 0.549, 95%CI 0.336-0.889, p = 0.017). Kaplan-Meier analysis indicated that in patients with bone metastases and liver-lung metastases, PTR could improve survival outcomes.

Conclusion: Liver-lung metastases and bone metastases in patients with de novo stage IV BC could enhance both OS and CSS through PTR.

释放生存优势：对新发 IV 期乳腺癌患者进行原发肿瘤切除术。

背景：对于新发IV期乳腺癌（BC）患者而言，原发肿瘤切除术（PTR）在何种情况下可带来益处仍不明确：对于新发 IV 期乳腺癌（BC）患者而言，原发肿瘤切除术（PTR）在何种情况下可带来益处仍不清楚：SEER数据库提供了新发IV期乳腺癌患者的治疗数据。我们筛选了2010年至2015年确诊的转移性BC病例，主要终点是总生存期（OS）和癌症特异性生存期（CSS）：共有 9252 例 IV 期新发 BC 患者入选。在OS方面，系统治疗（ST）的中位生存时间（MST）为38个月，而ST加PTR的中位生存时间（MST）为52个月（P P P P = 0.009）。CSS：骨转移（aHR 0.655，95%CI 0.571-0.751，p p = 0.017）。Kaplan-Meier分析表明，对于骨转移和肝肺转移患者，PTR可改善生存预后：结论：肝肺转移和骨转移的新发 IV 期 BC 患者可通过 PTR 提高 OS 和 CSS。
