摘要

本回顾性研究旨在比较吲哚菁绿（ICG）、锝-99 （Tc-99m）和联合技术（ICG + Tc-99m）在临床淋巴结阴性早期乳腺癌患者术前和术后新辅助化疗（NAC）中前哨淋巴结（SLN）检测的敏感性。方法纳入2021年12月至2024年5月期间接受乳腺手术并进行SLN活检的乳腺癌患者。在SLN活检中，ICG和Tc-99m联合使用。主要结局是比较ICG、Tc-99m和联合技术的SLN检出率（每例）和节点检出率（每个节点）。结果176例患者（术前128例，术后48例）共发现sln 326例。ICG和Tc-99m在术前（96.1%比95.3%,P = 0.65）和术后（89.6%比85.4%,P = 0.41） SLN检出率无显著差异。与Tc-99m相比，ICG组鉴定出的sln的平均数量更高(1.6±1.0比1.4±0.9,P <；0.001)。ICG的总淋巴结检出率高于Tc-99m (86.2% vs. 74.2%, P <；0.001)。与单独使用Tc-99m相比，使用联合技术显著提高了SLN的检出率，特别是在nac后（93.8% vs 85.4%）。0.05)，假阴性率为2.1%。结论在术前和NAC情况下，sicg对SLN的检测具有高灵敏度，与Tc-99m相当。使用双示踪剂也显著提高了NAC后SLN的检出率，这表明ICG可能是一种有效的SLN定位替代示踪剂，与NAC无关。

Comparative efficacy of indocyanine green and Tc-99m for sentinel lymph node biopsy in breast cancer: Upfront surgery and post-neoadjuvant chemotherapy

Background

This retrospective study aimed to compare the sensitivity of sentinel lymph node (SLN) detection using indocyanine green (ICG), Technetium-99 (Tc-99m), and combined technique (ICG + Tc-99m) in clinical node-negative early-stage breast cancer patients, both in upfront surgery and post-neoadjuvant chemotherapy (NAC) settings.

Method

Breast cancer patients who underwent breast surgery with SLN biopsy from December 2021 to May 2024 were enrolled. Both ICG and Tc-99m were used in combination during the SLN biopsy. The primary outcome was the SLN detection rate (per case) and nodal detection rate (per node) compared between ICG, Tc-99m, and combined technique.

Results

176 patients (128 upfront surgery, 48 post-NAC) were analyzed and a total of 326 SLNs were identified. The SLN detection rate was not different between ICG and Tc-99m in upfront surgery (96.1 % vs. 95.3 %, P = 0.65) and post-NAC (89.6 % vs. 85.4 %, P = 0.41). The mean number of identified SLNs was higher with ICG compared to Tc-99m (1.6 ± 1.0 vs. 1.4 ± 0.9, P < 0.001). ICG exhibited a higher overall nodal detection rate than Tc-99m (86.2 % vs. 74.2 %, P < 0.001). Using the combined technique significantly increased the SLN detection rate particularly in post-NAC compared to Tc-99m alone (93.8 % vs 85.4 %, P < 0.05) with a false negative rate of 2.1 %.

Conclusions

ICG demonstrated high sensitivity for SLN detection, comparable to Tc-99m in both upfront surgery and NAC settings. Using dual tracers also significantly improved the SLN detection rate in post-NAC setting, suggesting that ICG may serve as an effective alternative tracer for SLN mapping, regardless of NAC.
