Pattern of initial metastasis in the cervical lymph node from papillary thyroid carcinoma

Purposes

This study attempted to reveal the pattern of initial lymphatic spread in order to investigate the clinical significances of lymph node metastasis in papillary thyroid carcinoma (PTC) since such information has yet to be elucidated in previous studies.

Methods

This study reviewed 501 consecutive patients with PTC who had been surgically treated, accompanied by routine node dissection of the central, and lateral compartments. Thirty-eight cases were found to have only one metastatic node, and 62 cases were found to have 2 or 3 metastatic nodes. The locations of these metastatic nodes were mapped, and evaluated.

Results

The initial lymph node metastasis occurred equally in the lateral and central compartments (19 vs. 19 nodes). Metastatic nodes were more frequently found in the central compartment (60 and 65 %) in cases with 2- and 3-node involvements. Twenty-two (60 %) and 33 (65 %) cases had at least one instance of lateral node involvement in those cases, respectively.

Conclusions

The current results demonstrated the pattern of initial lymphatic spread in PTC cases, and indicated the importance of evaluating the lateral nodes of at least compartments III and IV for accurate pathological staging, as well as for investigating the nature of the disease.

Parapharyngeal lymph node metastasis: an unusual presentation of papillary thyroid carcinoma

BACKGROUND: Parapharyngeal space nodal metastases are usually secondary to malignancies of the pharynx and sinonasal tract, although localization of lymphomas is also possible. Parapharyngeal metastases arising from thyroid papillary carcinoma are instead an exceedingly rare event, with only 10 cases reported up to now in the literature. METHODS: We describe two cases of parapharyngeal metastasis from thyroid papillary carcinoma in a man and a woman, aged 40 and 52 years, respectively. RESULTS: Both patients had a lesion that clinically appeared to be located in the parapharyngeal space; they underwent CT and MRI, which detected a cystic mass in the poststyloid compartment. In the first patient, fine-needle aspiration cytology failed in identifying the histologic nature of the lesion, which was excised through a transcervical approach. A diagnosis of metastatic thyroid papillary carcinoma was rendered and therefore the patient underwent total thyroidectomy. In the second patient, a total thyroidectomy, previously scheduled for multinodular goiter, was performed along with the removal of the parapharyngeal mass. Definitive histologic findings revealed that the two parapharyngeal masses were cystic metastases from a thyroid papillary carcinoma. Both patients received postoperative 131I treatment. Twenty-four months after surgery, the first patient is free of disease, whereas the second one has clear signs of abnormal 131I uptake in the lungs. CONCLUSIONS: The differential diagnosis of a parapharyngeal poststyloid mass should also include metastasis from thyroid papillary carcinoma. When the lesion displays a cystic appearance on imaging, it is advisable to rule out a thyroid primary by ultrasonographic examination. The occurrence of a metastasis in such unusual site, even though rarely reported, does not seem to significantly affect the prognosis of the disease.

Risk factors for lateral lymph node metastasis of papillary thyroid carcinoma in children

IntroductionLateral cervical lymph node metastases (LNM) for pediatric patients with papillary thyroid cancer (PTC) is a poor prognostic factor. We aimed to identify risk factors for lateral LNM.MethodsThis retrospective study had included 48 pediatric patients with papillary thyroid cancer underwent total thyroidectomy and central cervical lymphadenectomy at K hospital from 2016 to 2020.ResultsThe number of patients in each T stage was as follows: 24 (50.0%) in stage 1, 9 (18.7%) in Stage 2, 8 (16.7%) in Stage 3, and 7 (14.6%) in Stage 4. Most of the patients had LNM with N1a and N1b rates of 83.3% and 62.5%, respectively. Lung metastases were observed at presentation in three patients (6.3%). Univariate analysis revealed that age (p = 0.021), male (p = 0.011), tumor size > 10 mm (p = 0.002), multifocality (p < 0.001), extrathyroidal extension (p = 0.001) and central LNM (p < 0.001) were factors that increase the risk of metastasis to lateral LNM.ConclusionApproximately 62.5% of pediatric patients with PTC exhibited lateral LNM at the time of diagnosis. Our study confirmed that multifocality, maximum tumor diameter, extrathyroidal extension and central LNM were independent risk factors for lateral LNM in pediatric PTC.Level of EvidenceLevel IV.     

Retropharyngeal node metastasis from papillary thyroid carcinoma

BACKGROUND: Papillary thyroid carcinomas commonly metastasize to paratracheal and jugular lymph nodes. Metastasis to the retropharyngeal node is rare for this tumor. METHODS: Five patients underwent surgical treatment for metastasis of thyroid papillary carcinoma to the retropharyngeal lymph nodes that presented as a parapharyngeal or retropharyngeal mass. All patients had a history of total or subtotal thyroidectomy as their initial treatment. Among them, 3 patients had undergone ipsilateral modified radical neck dissection at their initial treatment. The other 2 patients had a history of bilateral or ipsilateral modified neck dissection for their subsequent cervical lymph node metastases. RESULTS: Metastatic retropharyngeal nodes were successfully resected via transcervical approach in all patients. Although aspiration and difficulty in swallowing were observed in 2 patients after surgical treatment for metastatic retropharyngeal nodes, these complications spontaneously resolved within a few months. CONCLUSIONS: This study suggests that neck dissection and/or metastatic cervical lymph nodes might alter the direction of lymphatic drainage to the retrograde fashion, resulting in the unusual metastasis to the retropharyngeal lymph nodes. Although the cases described here are rare, metastasis to the retropharyngeal node should be considered at the follow-up for thyroid papillary carcinoma. Because these metastases will be missed by routine ultrasonography of the neck, periodic CT scan or MRI is recommended for follow-up, especially for patients with a history of neck dissection.     

甲状腺乳头状癌颈侧区淋巴结转移的危险因素研究进展

颈侧区淋巴结转移(LLNM)是甲状腺乳头状癌(PTC)患者术后预后不良的重要预测因素。手术前LLNM的漏诊将增加复发风险以及伴随的二次手术。对于具有LLNM危险因素的PTC患者,应放宽颈侧区肿大淋巴结穿刺活检指征,有助于术前发现更多隐匿的颈侧区转移淋巴结,制定更恰当的颈部淋巴结清扫范围。因此,本文就PTC患者LLNM规律及危险因素作一综述。

目的探讨影响甲状腺乳头状癌颈淋巴结跳跃性转移的相关危险因素。 方法回顾性分析2013年6月至2018年1月161例甲状腺癌患者行甲状腺切除术的临床资料,根据是否发生淋巴结跳跃性转移分为两组,运用SPSS 24.2软件进行统计分析。分类及等比数据采用频数、构成比进行统计描述,比较采用χ²检验。对单因素分析有意义的变量进行Logistic回归分析;以P<0.05为差异有统计学意义。 结果161例患者中共有25例患者发生淋巴结跳跃性转移,淋巴结跳跃性转移发生率为15.5%;单因素分析显示年龄、肿瘤大小及肿瘤位置则与跳跃性转移的发生密切相关(P<0.05);多因素分析结果显示,原发灶直径≤1 cm(OR＝0.182, 95%CI＝0.070～0.472, P＝0.000)与肿瘤累位于甲状腺上极(OR＝0.218, 95%CI＝0.082～0.574, P＝0.002)均为跳跃性颈侧区淋巴转移的独立危险因素。 结论甲状腺乳头状癌患者肿瘤位置位于上极、直径≤ 1 cm与跳跃转移密切相关;对于此类患者必要时需行患侧颈侧区淋巴结清扫,以降低临床甲状腺乳头状癌术后淋巴结转移风险。
