PURPOSE Insertion of radiopaque markers is helpful for tumor localization in patients receiving neoadjuvant chemotherapy (NAC) followed by breast-conserving surgery (BCS). The aim of this retrospective study was to investigate the pathologic margin status in patients with single or double marker insertion. METHODS We reviewed the records of 130 patients with marker insertion prior to NAC followed by BCS from January 2016 to September 2019. Under ultrasonography guidance, single or double markers were inserted to localize a tumor in the breast. The incidence of additional resection after frozen biopsy and re-excision after permanent pathologic diagnosis was analyzed. RESULTS In a total of 130 patients, 104 had a single marker in the center of the tumor and 26 had double markers at the periphery of the tumor before NAC. Among 69 patients with residual invasive tumors after NAC, there was no difference in the additional resection rate after frozen biopsy (single vs. double markers; 14.3% vs. 38.5%, P = .059) or the re-excision rate after final pathologic diagnosis (0% vs. 7.7%, P = .188). After propensity score matching for tumor size and subtypes, the two groups showed no differences in the additional resection rate after frozen biopsy (7.7% vs. 19.2%, P = .139) or the re-excision rate (0% vs. 3.8%, P = .308). After a median follow-up of 19 months (range 8-48 months), local recurrence-free survival did not differ between the two groups (log-rank P = .456). CONCLUSIONS Number of inserted markers for tumor localization did not affect the pathologic margin status after BCS.

在接受新辅助化疗的乳腺癌患者中插入单或双不透射线标记物进行肿瘤定位后切缘状态的比较。

目的 插入不透射线标记有助于在接受新辅助化疗 (NAC) 后进行保乳手术 (BCS) 的患者中进行肿瘤定位。这项回顾性研究的目的是调查单标记或双标记插入患者的病理切缘状态。方法 我们回顾了 2016 年 1 月至 2019 年 9 月在 NAC 和 BCS 之前插入标记物的 130 名患者的记录。在超声引导下,插入单个或双标记物以定位乳房中的肿瘤。分析冷冻活检后再次切除和永久病理诊断后再次切除的发生率。结果 在总共 130 名患者中,104 名在 NAC 之前在肿瘤中心具有单一标志物,26 名在肿瘤外围具有双重标志物。在 NAC 后残留浸润性肿瘤的 69 名患者中,冷冻活检后的额外切除率(单标记物与双标记物;14.3% 与 38.5%,P = .059)或最终病理学后的再次切除率没有差异诊断(0% 对 7.7%,P = .188)。在对肿瘤大小和亚型进行倾向评分匹配后,两组在冷冻活检后的额外切除率(7.7% vs. 19.2%,P = .139)或再次切除率(0% vs. 3.8%)方面没有差异, P = .308)。中位随访 19 个月(范围 8-48 个月)后,两组的局部无复发生存期没有差异(对数秩 P = .456)。结论 插入的肿瘤定位标志物的数量不影响 BCS 后的病理切缘状态。冷冻活检后的额外切除率(单标记物与双标记物;14.3% 与 38.5%,P = .059)或最终病理诊断后的再次切除率(0% 与 7.7%,P = .188)。在对肿瘤大小和亚型进行倾向评分匹配后,两组在冷冻活检后的额外切除率(7.7% vs. 19.2%,P = .139)或再次切除率(0% vs. 3.8%)方面没有差异, P = .308)。中位随访 19 个月(范围 8-48 个月)后,两组的局部无复发生存期没有差异(对数秩 P = .456)。结论 插入的肿瘤定位标志物的数量不影响 BCS 后的病理切缘状态。冷冻活检后的额外切除率(单标记物与双标记物;14.3% 与 38.5%,P = .059)或最终病理诊断后的再次切除率(0% 与 7.7%,P = .188)。在对肿瘤大小和亚型进行倾向评分匹配后,两组在冷冻活检后的额外切除率(7.7% vs. 19.2%,P = .139)或再次切除率(0% vs. 3.8%)方面没有差异, P = .308)。中位随访 19 个月(范围 8-48 个月)后,两组的局部无复发生存期没有差异(对数秩 P = .456)。结论 插入的肿瘤定位标志物的数量不影响 BCS 后的病理切缘状态。在对肿瘤大小和亚型进行倾向评分匹配后,两组在冷冻活检后的额外切除率(7.7% vs. 19.2%,P = .139)或再次切除率(0% vs. 3.8%)方面没有差异, P = .308)。中位随访 19 个月(范围 8-48 个月)后,两组的局部无复发生存期没有差异(对数秩 P = .456)。结论 插入的肿瘤定位标志物的数量不影响 BCS 后的病理切缘状态。在对肿瘤大小和亚型进行倾向评分匹配后,两组在冷冻活检后的额外切除率(7.7% vs. 19.2%,P = .139)或再次切除率(0% vs. 3.8%)方面没有差异, P = .308)。中位随访 19 个月(范围 8-48 个月)后,两组的局部无复发生存期没有差异(对数秩 P = .456)。结论 插入的肿瘤定位标志物的数量不影响 BCS 后的病理切缘状态。两组之间的局部无复发生存期没有差异(对数等级 P = .456)。结论 插入的肿瘤定位标志物的数量不影响 BCS 后的病理切缘状态。两组之间的局部无复发生存期没有差异(对数等级 P = .456)。结论 插入的肿瘤定位标志物的数量不影响 BCS 后的病理切缘状态。
