Abstract
BACKGROUND The status of central lymph nodes is crucial for determining the surgical approach to papillary thyroid carcinoma (PTC). Because of the differences between genders in central lymph node metastasis (CLNM), we aimed to construct separate predictive models for CLNM according to gender. METHODS In our study, a total of 1258 PTC patients who underwent thyroid cancer surgery from September 2021 to March 2023 were analyzed retrospectively. The data were analysed univariately and multivariately using SPSS software grouped according to gender and nomograms of CLNM were plotted using R software. The variables included in this study were sex, Age, body mass index, Diabetes, chronic lymphocytic thyroiditis (CLT), Suspicious central lymph node (SCLN), A/T, Margin, Microcalcification (MC), BRAF, Number, Location, CLNM. RESULTS The preoperative nomogram in male patients included four clinical variables: CLT, Margin, Number, Size. The preoperative nomogram of female patients included six clinical variables: Age, SCLN, Margin, MC, Number, Size. The calibration curves showed great agreement in both the training group and the validation group. The decision curve analysis showed the feasibility of nomogram in predicting CLNM in both man and woman. CONCLUSION Based on the successful establishment of nomogram, we can analyze the variability of CLNM between male and female, which may provide clinicians with personalized clinical schemes in the treatment of PTC.

Cancer Manag Res 2021; 13:1551-1558. [PMID: 33623434 PMCID: PMC7896733 DOI: 10.2147/cmar.s295420] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2020] [Accepted: 01/29/2021] [Indexed: 12/24/2022] Open
Abstract
Purpose Papillary thyroid carcinoma (PTC) in children and adolescents is prone to lateral lymph node metastasis (LNM), which is a high-risk factor for recurrence. However, few studies focused on identifying risk factors and establishing prediction models for lateral LNM of PTC in children and adolescents. Patients and Methods We retrospectively reviewed consecutive cases of children and adolescents with PTC undergoing thyroidectomy and cervical lymph node dissection between January 2009 and December 2019. The demographics and clinicopathologic features were collected and analyzed. Results A total of 102 children and adolescents with PTC were enrolled in our study; 51 of whom had lateral LNM (50%). After adjusting for other risk factors, the independent risk factors for lateral LNM were multifocality (odds ratio [OR]: 6.04; 95% confidence interval [CI]: 1.653–22.092; p=0.007), tumor size (OR: 1.752; 95% CI: 1.043–2.945; p=0.034), and the number of central LNM (OR: 1.23; 95% CI: 1.028–1.472; p=0.023). The formula of the combined predictor is: Multifocality + 0.31 × Tumor size + 0.115 × Number of central LNM. The area under the receiver operating characteristic curve of multifocality, tumor size, number of central LNM, and the combined predictor was 0.706, 0.762, 0.748, and 0.855, respectively. When the value of the combined predictor was ≥2.2744, lateral LNM could be predicted. The sensitivity and specificity of the predicted value were 82.4% and 74.5%, respectively. Conclusion The independent risk factors for lateral LNM in children and adolescents with PTC were multifocality, tumor size, and the number of central LNM. The prediction model can better predict the presence of lateral LNM.

Abstract
BACKGROUND Thyroid cancer is the most common malignancy of the endocrine system worldwide. Papillary thyroid cancer (PTC) is the most common pathologic type. The preoperative diagnosis of PTC and central lymph node metastasis (CLNM) or metastatic tendency is of great clinical significance to the diagnosis, treatment and prognosis of these patients. This study was conducted to investigate the correlation between ultrasound features and central CLNM of PTC. METHODS This study retrospectively analyzed patients who underwent PTC surgery and central lymph node dissection in the Department of Surgery, Beijing Tiantan Hospital, from January 2019 to February 2020. According to the inclusion and exclusion criteria, data from 136 patients were ultimately included, and the clinical and ultrasonic data of the patients were analyzed by multivariate regression to evaluate the correlation among grayscale ultrasound (US), superb microvascular imaging (SMI) and contrast-enhanced ultrasound (CEUS) features of thyroid nodules and CLNM of PTCs. RESULTS The multivariate analysis showed that tumor size, multifocality, microcalcification characteristics, SMI vascularization, and CEUS evaluation of contact with the adjacent capsule were correlated with PTC metastasis (P=0.008, P=0.001, P=0.028, P=0.041, and P< 0.001, respectively). Comparisons of the area under the ROC curves revealed that the area under the ROC curve of the degree of nodular invasion into the thyroid capsule was the largest (AUC: 0.754). The sensitivity and specificity for evaluating CLNM of PTC were 67.7% and 83.1%, respectively. CONCLUSIONS Ultrasound characteristics of the following features are associated with a high risk of lymph node metastasis in PTCs: maximum diameter of nodules ≥1 cm, multifocality, ≥5 microcalcifications, abundant blood flow of SMI in nodules and nodule contact with the thyroid capsule ≥25% under CEUS. Ultrasound has clinical value in the preoperative evaluation of CLNM of PTCs.

Abstract
BACKGROUND Data on thyroid surgery in children are scarce. OBJECTIVE Analyze outcome data on thyroid surgery in a pediatric population. DESIGN Medical record review. SETTING Tertiary health care institution. PATIENTS AND METHODS We collected demographic and clinical data on patients 18 years or younger who had thyroid surgery in the period 2000 to 2014. Descriptive data are presented. MAIN OUTCOME MEASURES Indications for thyroidectomy, thyroid pathology, complications, length of stay, and radioactive iodine treatment and recurrences. SAMPLE SIZE 103. RESULTS Of 103 patients who underwent 112 thyroidectomy procedures, 80 (78%) were females and the mean age at operation was 13.2 years. and 17 (16%) were associated with multiple endocrine neoplasia type 2. There was no history of radiation exposure. Eighty-one patients (78%) had fine needle aspiration (FNA) which correlated with the final histopathology in 94% of cases. Sixty-six patients (64%) had malignant cancer (61 papillary), 44 (74.6%) of 59 patients who had neck dissection had lymph node metastasis and 7 (11%) had distant metastases to the lung. Procedures included total thyroidectomy (50%), hemithyroidectomy (17%), completion (31%), and subtotal thyroidectomy (2%). Twenty-three patients (22%) developed hypocalcemia (3 permanent) and 6 (5.8%) had unilateral recurrent laryngeal nerve injury (3 permanent). Patients were followed up for a mean duration of 71.7 months (median 60 months). Of 66 patients with thyroid cancer, 43 (65%) received radioactive iodine, and 10 (15%) had recurrence. CONCLUSION Malignancy is the commonest indication for thyroid surgery in children and FNA is highly diagnostic. Hypocalcemia and recurrent laryngeal nerve injury are significant complications. The recurrence rate in thyroid cancer is 15%. LIMITATIONS Retrospective. CONFLICT OF INTEREST None.

Abstract
Cervical regional lymph node involvement (CRLNI) is common in papillary thyroid microcarcinoma (PTMC), but the way to deal with cervical lymph node involvement of clinically negative PTMC is controversial. We studied data of patients histologically confirmed PTMC in the Surveillance, Epidemiology, and End Results (SEER) Program and Department of Surgical Oncology in Hangzhou First People's Hospital (China). We screened 6 variables of demographic and clinicopathological characteristics as potential predictors and further constructed a lymph node involvement model based on the independent predictors including age, race, sex, extension, multifocality and tumor size. The model was validated by both the internal and the external testing sets, and the visual expression of the model was displayed by a nomogram. As a result, the C-index of this predictive model in the training set was 0.766, and the internal and external testing sets through cross-validation were 0.753 and 0.668, respectively. The area under the receiver operating characteristic curve (AUC) was 0.766 for the training set. We also performed a Decision Curve Analysis (DCA), which showed that predicting the cervical lymph node involvement risk applying this nomogram would be better than having all patients or none patients use this nomogram.

Abstract
Background Detection of distant metastasis (DM) is important in differentiated thyroid cancer (DTC). This study aimed to investigate the synergic effects of histology subtype, tumor size, and lymph node metastasis (LNM) status on the occurrence of DM in DTC. Methods We collected data of 96,788 patients with DTC. Univariate and multivariate analyses were conducted to identify the risk factors of DM. Relative excess risk of synergic effect, attributable proportion of synergic effect, and synergy index were then calculated to assess synergic effects. Further, Kaplan-Meier method using the log-rank test and receiver operating characteristic (ROC) curves were utilized. Results Age at diagnosis (P<0.001), sex (P<0.001), race (P<0.01), tumor size (P<0.001), N stage (P < 0.001), histology subtype (P<0.001), and extrathyroidal extension (P<0.001) were risk factors for DM in both univariate and multivariate analyses. We also found a significant additive synergic effect between histology subtype and LNM, and between tumor size and LNM on DM in the DTC patients. In addition, patients with follicular thyroid cancer and N1 stage had the sharpest decline in cancer-specific survival curves (P<0.001) and all-cause survival curves (P<0.001) compared to patients with other combinations of histology subtype and N stage. Similar results were obtained in patients with larger tumors (≥10 mm) and N1 stage. The areas under the curve of histology subtype, tumor size, and LNM status were 0.569, 0.744, and 0.681, respectively. Conclusions Age at diagnosis, sex, race, tumor size, N stage, histology subtype, and extrathyroidal extension are risk factors for DM in DTC patients. LNM has a synergic effect with either follicular thyroid histology or larger tumor size for higher risk of DM which is important for diagnosing DM.

Abstract
BACKGROUND Threshold numbers for defining adequacy of lymph node (LN) yield have been determined for evaluation of occult nodal disease during papillary thyroid cancer (PTC) surgery. This study assesses the prevalence of adequate LN yield and estimates its association with patient clinicopathologic characteristics. MATERIALS AND METHODS Adult patients with cN1 pT1b or pT2 and cN0 or cN1 pT3 M0 PTC ≥1 cm who received surgery with ≥1 LN resected were identified from the National Cancer Database, 2004-2015. Adequate yield was defined as removing ≥6, 9, and 18 LNs for pT1b, pT2, and pT3 stages, respectively, based on recently published literature. Univariable and multivariable logistic regression were used to determine factors associated with adequate yield. RESULTS A total of 23,131 patients were included; 7544 (32.6%) had adequate LN yield. Rate of adequate yield increased from 19.9% to 36.6% over time. After adjustment, patients at academic facilities were more likely to have adequate yield than those at community centers [OR 1.94 (95% CI 1.55-2.41), P < 0.001]. Patients with more advanced tumors were less likely to have adequate yield (pT1b: 75.9% versus pT2: 64.5% versus pT3: 24.6% adequate LN yield, P < 0.001). Patients with adequate LN yield were 0.89 times likely to receive radioactive iodine compared with those with inadequate yield [OR 0.98 (95% CI 0.81-0.98), P = 0.02]. CONCLUSIONS The rate of adequate LN yield has increased over time, but only a minority of lymphadenectomies performed for PTC can be defined as adequate. Disparities still exist based on patient and facility characteristics; patients with more advanced tumors appear less likely to have adequate LN yield.

Abstract
Cervical lymph node metastasis (CLNM) is common in differentiated thyroid cancer (DTC). Radioiodine-131 (131I) treatment is recommended for the removal of residual thyroid tissue following thyroidectomy. To date, the effect of 131I therapy on the outcomes of patients with DTC with CLNM is unclear. The aim of the present study was to evaluate the final outcome of patients with DTC with CLNM according to 131I administration, and to analyze the factors that may affect clinical outcomes. A total of 357 patients with DTC with CLNM were recruited and divided into three groups: Those who received 2, 3 or 4 doses of 131I therapy, respectively. Successful ablation was defined as levels of stimulated serum thyroglobulin <2 ng/ml in the absence of CLNM. The rates of successful ablation were 80.35 (229/285), 76.36 (42/55) and 70.59% (12/17) for patients who received 2, 3 and 4 doses, respectively. The patients with DTC with CLNM who were <45 years old, with tumor sizes <2 cm, solitary nodules and TNM stage I-II disease exhibited significantly higher rates of successful ablation compared with the patients who were ≥45 years old, with tumor size ≥2 cm, multiple nodules and stage III-IV disease. Multivariate analyses revealed that tumor size, number of nodules and TNM stage were independent risk factors associated with successful ablation in patients with DTC with CLNM who received 2 doses of 131I therapy. 131I administration is a useful therapy to eradicate cervical lymph node metastasis in patients with DTC, and may be preferentially indicated in patients with DTC with CLNM who are aged <45 years, with tumor sizes <2 cm, solitary nodules and lower TNM stages, in order to control and prevent recurrence and/or metastases.

Abstract
OBJECTIVE The aim of this study was to explore the risk factors that were associated with central lymph node metastases (CLNM) in papillary thyroid carcinoma (PTC) patients. METHODS A total of 180 patients with PTC who underwent surgery in our hospital between January 2014 and December 2016 were identified retrospectively. The relationship between clinicopathological factors and CLNM were analyzed by univariate and multivariate logistic regression. RESULTS The incidence of CLNM was 67.8% (122/180) in PTC patients. Univariate analysis showed that multifocality (p = 0.002), HT (p < 0.001) and LVI (p < 0.001) were significant associated with CLNM. No significant associations were found between factors and CLNM, including age, gender, tumor size and ETE. Multivariate logistic regression analysis showed that multifocality (p = 0.011), HT (p < 0.001) and LVI (p < 0.001) were independent predictors of CLNM in PTC patients. CONCLUSIONS Our study identified several independent risk factors predicting CLNM in PTC patients, such as multifocality, HT and LVI. The CLNM is very common in PTC patients, and routine prophylactic central neck dissection (PCND) may recommended in PTC patients with those risk factors of CLNM.

Abstract
OBJECTIVES WDTC (papillary and follicular thyroid cancer) make up around 90% of all thyroid tumours. Overall, the prognosis in patients with WDTC is excellent. However, there are small cohorts of patients who experience a more aggressive form of disease which is often associated with certain poor prognostic factors. Identifying these patients at an early stage is imperative for guiding treatment decisions. With recent developments in this area we plan to discuss the current evidence surrounding prognostic markers. METHODS The literature regarding prognostic factors in WDTC was reviewed using an electronic database Medline - Pubmed. Using the MeSH search engine specific prognostic factors including age, size, grade, lymph node involvement, distant metastasis, extension/invasion, ethnic background, radioactive iodine avidity, and thyroglobulin level and their association with WDTC were evaluated. A broader search of prognostic markers in thyroid cancer was also carried out to avoid missing other pertinent markers. RESULTS Multiple clinical and pathologic variables have been shown to be poor prognostic factors in WDTC with statistical significance. Extensive extrathyroidal extension and age may be the most important factors when predicting clinical outcomes in WDTC, although the age threshold may be increased from 45 to 55 years in due course. CONCLUSIONS Management of WDTC has changed considerably over the last two years as reflected in evolving British and American Thyroid Guidelines. In all cases a combined multi-disciplinary approach, with consideration of the available guidelines and stratification systems should be utilised when planning an individualised treatment program to offer the best contemporary care to WDTC patients.
