【摘 要】目的:本研究目的是分析子宫内膜癌前哨淋巴结(Sentinel LymphNode, SLN)在子宫内膜癌精准治疗中的意义。方法:选取2016 年7 月1 日至2018 年12 月31 日于哈尔滨市第一医院收治的26例子宫内膜癌患者,所有患者采用宫颈注射纳米碳,先行SLN 切除再行腹腔镜下系统性淋巴結切除,对所有切除的淋巴结均行苏木素-伊(Hematoxylin-eosin, HE)染色的常规病理检测。应用SPSS21.0 软件进行统计分析,计数资料采用χ2 检验或Fisher 确切概率法,并行一致性Kappa 检验。P<0.05 认为差异有统计学意义。结果:1 子宫内膜癌SLN 检出率为100%,双侧均检出SLN 占92.3%(24/26),仅单侧检出SLN 占7.7%(2/26,左侧2 例),准确性为100%,假阴性率为0,阴性预测值为100%。2 26 例子宫内膜癌患者共切除SLN 164 枚,占切除总淋巴结的26.1%(164/628),平均切除SLN 6.47 枚/人,平均切除SLN 比NSLN 少11.86枚/人。3 子宫内膜癌SLN 分布为闭孔区占53.2%(87/164),髂外区占23.7%(38/164)。结论:1、纳米碳是很好的子宫内膜癌SLN的示踪剂,宫颈部位注射示踪剂是显示SLN 较好的注射途径。2、子宫内膜癌SLN 主要位于闭孔区和髂外区。3 、在子宫内膜癌患者中行SLN 识别技术是安全、可行的。

【Abstract】Objective: The purpose of this study was to analyze the significance of Sentinel lymph node(SLN) in the accurate treatment of endometrial carcinoma.Methods: 26 patients with endometrial cancer were selected from July 1, 2016 to December 31, 2018 at Harbin No. 1 Hospital. All patients were treated with cervical injection of Nano carbon, SLN was removed first and laparoscopic systemic lymph node resection was performed. All removed lymph nodes were routinely pathologically examined for Sumusu(HE) staining. SPSS21 .0 software is used for statistical analysis. The counting data is measured using the 2 test or the Fisher exact probability method, and the parallel consistency Kappa test. P & lt; 0.05 The difference is considered to be statistically significant.Results: 1 endometrial carcinoma had 100 % SLN detection rate, 92.3 %(24/26) were detected on both sides, 7.7 %(2/26, 2 cases on the left) were detected on only one side, and the accuracy was 100 %. The false sex rate was 0, The negative prediction is 100 %. A total of 26 patients with endometrial cancer had SLN 164 removed, accounting for 26.1 per cent of total lymph nodes removed(164/628), with an average SLN of 6.47 resected per person and an average SLN of 11.86 less than NSLN. 3 The SLN distribution of endometrial carcinoma was 53.2 %(87/164) and 23.7 %(38/164).Conclusion: 1. Nanocarbon is a good tracer for SLN of endometrial carcinoma, and cervical injection tracer is a good injection route for SLN. 2, endometrial carcinoma SLN is mainly located in the closed hole area and the external iliac area. 3, in the endometrial cancer patients with SLN recognition technology is safe and feasible.

子宫内膜癌是影响广大妇女健康的常见恶性肿瘤之一,淋巴转移是其主要的转移方式。目前根据2016 年子宫肿瘤临床实践指南[1]推荐,子宫内膜癌治疗以全面分期手术为主。早期子宫内膜癌患者中仅有10%-15%发生了淋巴结转移[2],系统性淋巴结清扫带来的长期淋巴水肿却高达23%[3]。研究[4]提示,尚未发生转移的淋巴结具有正常的防御功能,因此,如何既可以获得淋巴结转移的信息,又可以避免广泛的淋巴结切除带来的手术风险,是亟待解决的问题。

为解决这一问题,前哨淋巴结(Sentinel Lymph Node, SLN)逐渐成为肿瘤外科中的研究热点[5]。若SLN 阴性,提示区域淋巴结无转移,则可避免常规的腹膜后淋巴结清扫,降低并发症的发生率,提高患者的生活质量。
