The aim of this study was to ascertain which factors determine success of sentinel node biopsy (SNB).
We conducted a retrospective review of 121 patients with head and neck squamous cell carcinoma undergoing SNB to stage the neck. All patients underwent the triple-diagnostic procedure of preoperative lymphoscintigraphy, intraoperative blue dye, and a gamma probe. Factors contributing to failure of SNB were identified.
SNB was unsuccessful in 12 of 121 patients (10%). Seven of the 12 patients had cT1/cT2 tumors, and 6 of these were located in the floor of mouth. SN identification was more likely to be successful in patients with cN0 necks, but this did not reach statistical significance (92% vs 84%, p = .268). Factors associated with failure included T classification (p = .01), tumor site (p = .05), and negative preoperative lymphoscintigraphy (p = .0174).
Successful sentinel lymph node harvest is related to primary tumor site, T classification, and the presence of nodes on preoperative lymphoscintigraphy.
本研究的目的是确定哪些因素决定前哨淋巴结活检(SNB)的成功。
我们对121例行SNB以进行颈部分期的头颈部鳞状细胞癌患者进行了回顾性研究。所有患者均接受了术前淋巴闪烁显像、术中蓝色染料和γ探针的三联诊断程序。确定了导致SNB失败的因素。
121例患者中有12例(10%)SNB未成功。12例患者中有7例为cT1/cT2肿瘤,其中6例位于口底。cN0颈部患者的前哨淋巴结识别更有可能成功,但未达到统计学意义(92%对84%,p = 0.268)。与失败相关的因素包括T分类(p = 0.01)、肿瘤部位(p = 0.05)和术前淋巴闪烁显像阴性(p = 0.0174)。
成功获取前哨淋巴结与原发肿瘤部位、T分类以及术前淋巴闪烁显像中淋巴结的存在有关。
