Abstract
Objective:To investigate the detection rate and metastasis rate of delphain lymph node (DLN)in thyroid papillary adenocarcinoma(PTC) and to analyze the risk factors for DLN metastasis. Methods:The clinicopathological data of 200 PTC patients admitted to the from January 2018 to June 2020 were retrospectively analyzed, and the detection of DLN was clearly recorded in the pathological reports of all patients. The number of DLN detected, the number of metastasis, the detection rate and the metastasis rate were counted. The clinicopathological factors that might affect DLN metastasis were analyzed by univariate analysis and multivariate Logistic regression analysis, including gender, age, tumor size and tumor location. Results:DLN was detected in 121 of 200 PTC patients, with a detection rate of 60.50% (121/200). DLN metastasis was found in 46 of the 121 patients with a metastasis rate of 38.02% (46/121).Univariate analysis showed that tumor diameter, multiple foci, capsular invasion, extradandular invasion, lymphatic vascular invasion, lymph node metastasis in central region (excluding DLN), and lateral cervical lymph node metastasis were the risk factors for DLN metastasis of PTC (P<0.05). Gender, age, tumor location, bilateral tumors, Hashimoto's thyroiditis and BRAFV600E mutation were not significantly correlated with DLN metastasis of PTC(P>0.05). The 7 variables with statistically significant differences in univariate analysis were incorporated into Logistic regression model for multivariate analysis, and the results showed that, Tumor diameter ≥1.0 cm, capsule invasion, lymphatic vascular invasion, lymph node metastasis in central region (excluding DLN), and lateral cervical lymph node metastasis were independent risk factors for DLN metastasis of PTC (OR= 3.386-9.186, P<0.05). The sensitivity and specificity of DLN metastasis in predicting central lymph node (excluding DLN) metastasis in PTC patients were 36.79% and 92.55%, respectively, while the sensitivity and specificity of DLN metastasis in predicting lateral cervical lymph node metastasis were 41.03% and 81.37%, respectively.The incidence of central lymph node metastasis (excluding DLN) in DLN-positive patients were was 4.94 times higher than that in DLN-negative patients, and the incidence of lateral neck lymph node metastasis in DLN-positive patients were 2.20 times higher than that in DLN-negative patients. Conclusion:The detection rate and metastasis rate of DLN in PTC patients were higher, DLN metastasis predicts more extensive lymph node metastasis, and DLN metastasis was related to multiple factors,among which tumor diameter ≥ 1.0 cm, capsule invasion, lymphatic vascular infiltration, lymph node metastasis in the central region (excluding DLN), and lateral cervical lymph node metastasis were independent risk factors for DLN metastasis of PTC. Therefore, PTC patients with the above characteristics should actively explore DLN and formulate appropriate surgical strategies.

Abstract
Objective To investigate the effect and clinical significance of Delphian lymph nodes (DLN) on the factors influencing papillary thyroid cancer (PTC) to provide individualized guidance for the surgical treatment of thyroid cancer. Methods Relevant studies from PubMed, Web of Science, the Cochrane Library, Embase, and China National Knowledge Infrastructure databases were searched until February 13, 2023. Stringent selection parameters were used to obtain included data and homogeneous articles. Analyses were performed using Revman 5.4 and SPSS software. A P-value of < 0.05 was considered statistically significant. Results Five studies were finally included in this study. The results revealed a higher risk of DLN metastasis (DLNM) in patients with tumor size >1cm, multifocality, and extrathyroidal extension (ETE) of the thyroid. The risk of central lymph node metastasis (CLNM) was 11.25 times higher in DLN-positive patients with PTC than in DLN-negative (OR = 11.25, 95% CI: 8.64-14.64, P < 0.05) patients. The risk of LLNM was 5.57 times higher in DLN-positive patients with PTC than in DLN-negative (OR = 5.57, 95% CI: 4.57-6.78, P < 0.001) patients. The risk of postoperative recurrence in DLN-positive patients with PTC was 3.49 times higher (OR = 3.49, 95% CI: 1.91-6.38, P < 0.001) than in DLN-negative patients with PTC. Conclusion Patients with tumor size >1 cm in diameter, multifocality, and ETE have an increased risk for DLN development. DLN-positive patients with central and lateral cervical lymph node metastasis and postoperative recurrence are at higher risk than DLN-negative patients.

Relationship between pretracheal and/or prelaryngeal lymph node metastasis and paratracheal and lateral lymph node metastasis of papillary thyroid carcinoma: A meta-analysis. Front Oncol 2022; 12:950047. [PMID: 36212418 PMCID: PMC9543714 DOI: 10.3389/fonc.2022.950047] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2022] [Accepted: 09/05/2022] [Indexed: 11/21/2022] Open
Abstract
Objective We conducted a meta-analysis to study the relationship between pretracheal and/or prelaryngeal lymph node metastasis and paratracheal and lateral lymph node metastasis in papillary thyroid carcinoma. Method A systematic literature search was conducted using PubMed, Embase, and the Cochrane Library electronic databases for studies published up to February 2022. The reference lists of retrieved articles were also reviewed. Two authors independently assessed the methodological quality and extracted the data. A random-effects model was used to calculate the overall pooled relative risk. Publication bias in these studies was evaluated using Egger’s test and Begg’s test. Results Twenty-five independent studies involving 10,525 patients were included in the meta-analysis. The pooled relative risk for ipsilateral and contralateral paratracheal lymph node metastasis was 3.01 (95% confidence interval [CI]: 1.66, 5.45) and 5.68 (95% CI: 2.50, 12.88), respectively, in patients with pretracheal lymph node metastasis. Among patients with prelaryngeal lymph node metastasis, the pooled relative risk for ipsilateral paratracheal and/or pretracheal contralateral paratracheal, and lateral lymph node metastasis was 2.02 (95% CI: 1.90, 2.14), 2.22 (95% CI: 1.34, 3.67), and 3.85 (95% CI: 2.89, 5.14), respectively. Conclusion Pretracheal lymph node metastasis and prelaryngeal lymph node metastasis were significantly associated with an increased likelihood of both ipsilateral lymph node metastasis and contralateral paratracheal lymph node metastasis in papillary thyroid carcinoma. Prelaryngeal lymph node metastasis was positively correlated with the incidence of lateral lymph node metastasis.

Nomograms Combining Ultrasonic Features With Clinical and Pathological Features for Estimation of Delphian Lymph Node Metastasis Risk in Papillary Thyroid Carcinoma. Front Oncol 2022; 11:792347. [PMID: 35004316 PMCID: PMC8733604 DOI: 10.3389/fonc.2021.792347] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2021] [Accepted: 11/25/2021] [Indexed: 11/16/2022] Open
Abstract
Background This work explores the clinical significance of Delphian lymph nodes (DLN) in thyroid papillary carcinoma (PTC). At the same time, a nomogram is constructed based on clinical, pathological, and ultrasonic (US) features to evaluate the possibility of DLN metastasis (DLNM) in PTC patients. This is the first study to predict DLNM using US characteristics. Methods A total of 485 patients, surgically diagnosed with PTC between February 2017 and June 2021, all of whom underwent thyroidectomy, were included in the study. Using the clinical, pathological, and US information of patients, the related factors of DLNM were retrospectively analyzed. The risk factors associated with DLNM were identified through univariate and multivariate analyses. According to clinical + pathology, clinical + US, and clinical + US + pathology, the predictive nomogram for DLNM was established and validated. Results Of the 485 patients with DLN, 98 (20.2%) exhibited DLNM. The DLNM positive group had higher positive rates of central lymph node metastasis (CLNM), lateral lymph node metastasis (LLNM), and T3b–T4b thyroid tumors than the negative rates. The number of CLNM and LLNM lymph nodes in the DLNM+ group was higher as compared to that in the DLNM- group. Multivariate analysis demonstrated that the common independent risk factors of the three prediction models were male, bilaterality, and located in the isthmus. Age ≥45 years, located in the lower pole, and nodural goiter were protective factors. In addition, the independent risk factors were classified as follows: (I) P-extrathyroidal extension (ETE) and CLNM based on clinical + pathological characteristics; (II) US-ETE and US-CLNM based on clinical + US characteristics; and (III) US-ETE and CLNM based on clinical +US + pathological features. Better diagnostic efficacy was reported with clinical + pathology + US diagnostic model than that of clinical + pathology diagnostic model (AUC 0.872 vs. 0.821, p = 0.039). However, there was no significant difference between clinical + pathology + US diagnostic model and clinical + US diagnostic model (AUC 0.872 vs. 0.821, p = 0.724). Conclusions This study found that DLNM may be a sign that PTC is more invasive and has extensive lymph node metastasis. By exploring the clinical, pathology, and US characteristics of PTC progression to DLNM, three prediction nomograms, established according to different combinations of features, can be used in different situations to evaluate the transfer risk of DLN.

Abstract
OBJECTIVE/HYPOTHESIS To evaluate the diagnostic accuracy of Delphian lymph node (DLN) metastasis for the prediction of central lymph node (CLN) metastasis and lateral lymph node (LLN) metastasis. METHODS Two authors independently reviewed the six databases (Cochrane database, Embase, Google Scholar, PubMed, SCOPUS, and Web of Science). Four parameters were extracted from each study: true positive, true negative, false positive, and false negative. The quality of the methodology was evaluated using the Quality Assessment of Diagnostic Accuracy Studies ver. 2 tool. RESULTS The diagnostic odds ratio of DLN in CLN metastasis was 8.859 (95% confidence interval [CI], 4.419; 16.578). The area under the summary receiver operating characteristic curve was 0.748. The diagnostic odds ratio of DLN in LLN metastasis was 7.61 (95% CI, 4.48; 12.94). The area under the summary receiver operating characteristic curve was 0.837. DLN metastasis was moderately predictive of CLN metastasis (sensitivity = 32%, specificity = 95%), LLN metastasis (sensitivity = 52%, specificity = 89%), and contralateral CLN metastasis (sensitivity = 46%, specificity = 85%). DLN metastasis had statistically significant correlation with specific clinicopathological characteristics, including younger age (< 45 years old), bilaterality, capsule invasion, extrathyroidal extension, lymphovascular invasion, male sex, multifocality, and tumor size (> 1 cm). CONCLUSIONS The higher specificities of DLN pathology may help predict central and lateral compartment involvement in patients with thyroid cancer.
