摘要
目的探讨乳腺癌内乳区前哨淋巴结活检术(IM—SLNB)对淋巴分期和辅助治疗方案的影响。方法前瞻性分析行SLNB的349例乳腺癌患者的临床资料,均经穿刺病理证实为乳腺癌。结合术前淋巴显像和术中叮探测仪定位内乳区前哨淋巴结(IM—SLN),经肋间行IM—SLNB,评估治疗策略改变的情况,分析IM—SLNB的成功率、并发症和学习曲线。结果349例患者中,IM—SLN显像248例(71.1%)。153例接受IM—SLNB的患者中,成功149例,IM—SLNB的成功率为97.4%,胸膜、内乳血管损伤的发生率分别为7.2%和5.2%,IM—SLN的转移率为8.1%(12/149)。行IM—SLNB后,患者的淋巴分期发生改变12例(8.1%),仅使1例(0.7%)系统辅助治疗策略发生改变。8.1%(12/149)的患者可以接受个体化内乳区放疗。结论IM—SLNB成功率高,安全性好,可以为乳腺癌患者提供精确的淋巴分期,并且指导个体化的内乳区放疗策略。
Objective The aim of this study was to determine the impact of routinely performed internal mammary sentinel lymph node biopsy (IM-SLNB) on the staging and treatment, and to analyze the success rate, complications and learning curve. Methods All patients with biopsy-proven breast cancer who underwent sentinel lymph node biopsy between 2012 and 2014 were included in a prospective analysis. Internal mammary sentinel lymph node biopsy (IM-SLNB) was performed in all patients with IM-SLN visualized on preoperative lymphoscintigraphy and/or detected by intraoperative gamma probe detection. The adjuvant treatment plan was adjusted according to the current guidelines. Results In a total of 349 patients, 249 patients (71.1%) showed internal mammary drainage. IM-SLNB was performed in 153 patients with internal mammary drainage, with a success rate of IM-SLNB of 97.4% (149/153). Pleural lesion and internal mammary artery bleeding were found in 7.2% and 5.2% patients, respectively. In 8.1% of patients (12/149) the IM-SLN was tumor positive. In the group of patients who underwent IM-SLNB, lymph node staging was changed in 8.1% of patients, and IMLNs radiotherapy was guided by these results, however, systemic treatment was changed in only 0.7% of the patients. Conclusions IM-SLNB has a high successful rate and good safety. Identification of internal mammary metastases through IM-SLNB may provide more accurate staging and guide the tailored internal mammary radiotherapy.
