摘要:

目的 探讨乳腺癌分子分型对保乳边缘状态以及预后的影响。方法 1 032 例拟保乳乳腺癌患者的临床病理资料进行回顾性分析,利用单变量及多变量分析分子分型、年龄及肿瘤大小等临床病理特征与阳性手术边缘以及预后的相关性。结果 20.3%(209/1 032)患者边缘阳性。多变量分析显示 Her⁃2+型乳腺癌、EIC 及阳性淋巴结与阳性边缘具有统计学相关性(P < 0.01);利用 Kaplan⁃Meier 生存曲线,不同分子分型的预后,在 DFS,LRRFS DMFS 差异有统计学意义(P < 0.05)。结论 Her⁃2+乳腺癌是保乳阳性边缘的独立影响因素;Luminal⁃HER⁃2分型和 HER⁃2+分型是保乳患者预后差的独立预后因素。

Abstract:

Objective To investigate the effect of molecular subtype on the margin statusof breast⁃conserving surgery(BCS)and prognosis. Methods We retrospectively reviewed the clinical and histopathologic data of 1 032 consecutive womenat the time of diagnosis with breast cancer deemed suitable for BCS treated with lumpectomy. Univariate and multivariate analyses were used to determine the relationship between the molecular subtype,age tumor size and positive surgical margins and prognosis. Results 20.3% of the(209/1 032)patients had evidence of cancer intheir cavity margins(CM). By multivariate analysis,the HER⁃2 BC subtype,EIC,pN stage were sig⁃ nificantly correlated with positive CMs(P < 0.01). Kaplan ⁃Meier survivalanalysis revealed statistically significant differencesin DFS,LRRFS,and DMFS,among the breast cancer subtypes(P < 0.05). Conclusion The HER⁃2 positive subtype is the predictive factor that is most associated with positive CMs. The luminal⁃HER⁃2 and HER⁃2 subtypesareindependent prognostic factors for worse outcomes in patients with breast⁃conserving surgery.
