BACKGROUND
There have been few reports on lymph node metastasis between sternocleidomastoid and sternohyoid muscle (originally LNSS) in clinically node positive (cN+) papillary thyroid carcinoma (PTC). Therefore, our objective was to investigate the significance of LNSS metastasis.
METHODS
A total of 115 patients with cN+ PTC underwent a neck dissection with LNSS, as a separate pathologic specimen to be analyzed for the correlation between LNSS and sex, age, tumor size, tumor site, initial or reoperative treatment, lateral cervical lymph nodes, and central compartment metastasis.
RESULTS
The positive rate of LNSS was 22.6%. LNSS metastasis was correlated with a primary site in the inferior pole, the lateral nodal metastasis, level III and level IV nodal metastasis, but not with other clinical parameters.
CONCLUSION
In cN+ PTC, especially a primary site in the inferior pole, level III and/or level IV metastasis, attention should be given to excising the nodal tissue in LNSS.
背景
在临床颈部淋巴结阳性（cN+）甲状腺乳头状癌（PTC）中，很少有关于胸锁乳突肌和胸骨舌骨肌之间（原 LNSS）淋巴结转移的报道。因此，我们的目的是探讨 LNSS 转移的意义。
方法
共有 115 例 cN+ PTC 患者接受了颈淋巴结清扫术，将 LNSS 作为单独的病理标本进行分析，以探讨 LNSS 与性别、年龄、肿瘤大小、肿瘤部位、初次或再次治疗、颈侧淋巴结和中央隔转移之间的相关性。
结果
LNSS 的阳性率为 22.6%。LNSS 转移与下极原发灶、侧方淋巴结转移、III 级和 IV 级淋巴结转移相关，但与其他临床参数无关。
结论
在 cN+ PTC 中，尤其是在下极原发灶、III 级和/或 IV 级转移的情况下，应注意切除 LNSS 中的淋巴结组织。
