1.Multidisciplinary expert consensus on thermal ablation for benign thyroid diseases, low-risk thyroid carcinoma, and metastatic cervical lymph nodes (2025 edition).
Chinese Journal of Internal Medicine 2025;64(7):614-624
Thermal ablation has proven an effective treatment modality for certain thyroid diseases. However, its indications remain the subject of significant debate both domestically and internationally. Over recent years, several international academic organizations have issued consensus statements, position papers, and guidelines concerning thyroid thermal ablation. In China, the Chinese College of Interventionalists (CCI), in collaboration with other relevant academic organizations, released the "Expert consensus on thermal ablation for thyroid benign nodes, microcarcinoma and metastatic cervical lymph nodes (2018 edition)". This consensus statement received widespread recognition within the field and contributed significantly to the standardization of thyroid thermal ablation therapy in China. With the continuous accumulation of evidence-based medical data, the need for a more stringent and standardized approach to thyroid thermal ablation has become evident. Accordingly, the Interventional Ultrasound Committee of the CCI, in collaboration with multiple academic organizations and experts, conducted extensive discussions and multiple revisions before finalizing the "Multidisciplinary expert consensus on thermal ablation for benign thyroid diseases, low-risk thyroid carcinoma, and metastatic cervical lymph nodes (2025 edition)". This updated consensus builds on the framework of the 2018 edition, refining indications and contraindications, emphasizing standardized treatment, and outlining future directions for research and clinical applications of thyroid thermal ablation technology.

OBJECTIVE:
To explore the clinical significance of extended pelvic lymph node dissection (EPLND) under the robot-assisted laparoscope in the treatment of high-risk PCa.
METHODS:
This study included 29 cases of high-risk PCa treated by robot-assisted laparoscopic radical prostatectomy and EPLND from April 2020 to January 2023. We collected the general data on the patients, recorded the status of dissection of the lymph nodes and postoperative complications, and analyzed the significance of EPLND.
RESULTS:
The patients were aged (69.3±6.6) years old, with the preoperative PSA level of 8.43-434 μg/L, Gleason score (GS) 6 in 1, GS 7 in 9, and GS ≥8 in 19 cases. The operation time averaged (97.2±15.7) min, with the mean blood loss of (30.5±11.2) ml, and 3-42 (median = 13) lymph nodes dissected, less than 10 in 10 cases, 11-19 in 12, and more than 20 in 7. Positive pelvic lymph nodes (median = 4) were found in 13 cases, with a positive rate of 44.8%. Positive incisal margin was observed in 11 cases (37.9%), lymphovascular invasion (LVI) in 4 (13.8%), and perineural invasion (PNI) in another 4 (13.8%). Lymph node metastasis was significantly correlated with positive incisal margin (P<0.05), but not with LVI, PNI or age (P>0.05). No significant vascular or nerve injuries occurred during the operation. GS 6 was detected in 1, GS 7 in 7, and GS ≥8 in 21 cases postoperatively.
CONCLUSION
Robot-assisted laparoscopic EPLND is an important strategy for the treatment of high-risk PCa, which contributes to accurate pathological staging of the malignancy. However, evidence is lacking for its benefit to the survival of high-risk PCa patients, and more follow-up studies are needed to confirm its treatment effect.

Sentinel lymph nodes (SLNs) are the first station of lymph nodes that extend from the breast tumor to the axillary lymphatic drainage. The pathological status of these LNs can predict that of the entire axillary lymph node. Therefore, the accurate identification of SLNs is necessary for sentinel lymph node biopsy (SLNB) to replace axillary lymph node dissection (ALND). The quality of life and prognosis of breast cancer patients are related to proper surgical treatment after the precise identification of SLNs. Some of the SLN tracers that have been identified include radioisotope, nano-carbon, indocyanine green (ICG), and methylene blue (MB). However, these tracers have certain limitations, such as pigmentation, radiation dangers, and the requirement for costly detection equipment. Ultrasound contrast agents (UCAs) have good specificity and sensitivity, and thus can compensate for some shortcomings of the mentioned tracers. This technique is also being applied to SLNB in patients with breast cancer, and can even provide an initial judgment on SLN status. Contrast-enhanced ultrasound (CEUS) has the advantages of high distinguishability, simple operation, no radiation harm, low cost, and accurate localization; therefore, it is expected to replace the traditional biopsy methods. In addition, it can significantly enhance the accuracy of SLN localization and shorten the operation time.

Objective:To investigate the correlation between preoperative platelet parameters and the clinicopathological features of differentiated thyroid cancer. Methods:We retrospectively analyzed the medical records of patients with thyroid tumors admitted to Zhongda Hospital affiliated to Southeast University and healthy adults with normal physical examination results in our hospital from January 2019 to December 2020, and collected their general information and preoperative blood routine data. Patients with undifferentiated thyroid cancer, diabetes, coronary heart disease, hematological diseases, kidney diseases, autoimmune diseases, genetic diseases, infectious diseases, other systemic tumors, hepatitis or cirrhosis, or those taking anticoagulants were excluded. The exclusion criteria for healthy adults were the absence of the above diseases and normal physical examination results. Differences in platelet parameters among the three groups were compared, and the correlation between clinicopathological characteristics of thyroid cancer, accompanying cervical lymph node metastasis, and platelet parameters of patients was analyzed. A multivariate logistic regression model was used to analyze the risk factors of thyroid cancer with cervical lymph node metastasis. Results:A total of 117 cases of differentiated thyroid cancer were collected, including 33 males and 84 females, with an average age of (41.64±12.25) years; 46 patients had benign thyroid tumors, including 15 males and 31 females, with an average age of (41.35±12.52) years; 50 healthy adults with normal physical examination results in our hospital during the same period were also included, including 18 males and 32 females, with an average age of(42.02±9.62) years, without underlying diseases. The platelet count of the differentiated thyroid cancer group was higher than that of the benign thyroid tumor group(t=-2.219, P=0.028) and the normal control group(t=2.069, P=0.04), while the platelet distribution width of the differentiated thyroid cancer group was lower than that of the benign thyroid tumor group(t=2.238, P=0.027) and the normal control group(t=-2.618, P=0.002). These differences were statistically significant. Preoperative age ≤45 years(χ²=4.225, P=0.04), tumor diameter>1 cm(χ²=4.415, P=0.036), PLT(t=-4.018, P<0.01) increase, and PDW(t=4.568, P<0.01) decrease were significantly correlated with cervical lymph node metastasis of thyroid cancer and had statistical significance. Univariate analysis showed that age ≤45 years(OR=0.447, 95%CI 0.206-0.970, P=0.042), tumor diameter>1 cm(OR=2.3, 95%CI 1.050-5.039, P=0.037), PLT(OR=1.012, 95%CI 1.005-1.019, P=0.001), and PDW(OR=0.693, 95%CI 0.518-0.827, P<0.01) were risk factors for cervical lymph node metastasis of thyroid cancer. The results of multifactorial logistic regression analysis showed that PLT(OR=1.008, 95%CI 1.001-1.016, P=0.026) and PDW(OR=0.692, 95%CI 0.564-0.848, P<0.01) were independent risk factors for thyroid cancer with cervical lymph node metastasis. Conclusion:PLT and PDW may be useful predictive factors for the differentiation of thyroid cancer malignancy and central lymph node metastasis.

Objective: To analyze the incidence and the related risk factors of retropharyngeal lymph node metastasis in patients with hypopharyngeal squamous cell carcinoma, evaluate the accuracy of preoperative enhanced CT in judging retropharyngeal lymph node metastasis, and investigate the impact of retropharyngeal lymph node metastasis on the prognosis. Methods: Retrospective analyses were made on 398 patients with hypopharyngeal squamous cell carcinoma who underwent surgery as the primary therapy and accepted retropharyngeal lymph node exploration and clearance during surgery in Shandong Provincial ENT Hospital from January 2014 to December 2019. Multivariate logistic regression analysis was used to clarify the related risk factors of retropharyngeal lymph node metastasis. Multivariate Cox regression analysis was used to investigate the impact of retropharyngeal lymph node metastasis on prognosis. The retropharyngeal lymph nodes of 218 cases with available preoperative enhanced CT images were evaluated by two experienced radiologists and compared with postoperative pathological results. Results: Retropharyngeal lymph node metastasis were confirmed in 54 of 398 (13.6%) cases according to postoperative pathology. The sensitivity and specificity of preoperative enhanced CT in the diagnosis of retropharyngeal lymph node metastasis were 34.6% and 91.1%, respectively, and the overall accuracy was 84.4%. Multivariate logistic regression analysis showed that the site of the primary lesion and pathological N stage were independent risk factors for retropharyngeal lymph node metastasis in hypopharyngeal squamous cell carcinoma. Patients with primary lesion located in the posterior wall of hypopharynx (OR=4.83, 95% CI: 1.27-18.40), N2 stage (OR=6.30, 95% CI: 2.25-17.67), and N3 stage (OR=26.89, 95% CI: 5.76-125.58) were prone to retropharyngeal lymph node metastasis. The 5-year overall survival rate of the 398 patients was 50.4%, and the 5-year disease-free survival rate was 48.3%. Multivariate Cox regression analysis showed that T stage, N stage, retropharyngeal lymph node metastasis, and radiotherapy were independent influencing factors for overall survival (T stage: HR=1.28, 95% CI: 1.06-1.54; N stage: HR=1.26, 95% CI: 1.14-1.40; retropharyngeal lymph node metastasis: HR=2.13, 95% CI: 1.47-3.08; radiotherapy: HR=0.54, 95% CI: 0.38-0.76) and disease-free survival of patients with hypopharyngeal squamous cell carcinoma (T stage: HR=1.26, 95% CI: 1.06-1.51; N stage: HR=1.25, 95% CI: 1.13-1.37; retropharyngeal lymph node metastasis: HR=2.24, 95% CI: 1.56-3.21; radiotherapy: HR=0.55, 95% CI: 0.40-0.77). Conclusions: Metastasis of retropharyngeal lymph nodes in hypopharyngeal squamous cell carcinoma is not rare. Enhanced CT is of low accuracy and limited value in diagnosing retropharyngeal lymph node metastasis. Primary lesions located in the posterior wall of the hypopharyngx, N2 stage, and N3 stage are independent high-risk factors for retropharyngeal lymph node metastasis. The prognosis of hypopharyngeal cancer patients with retropharyngeal lymph node metastasis is worse, and active surgical exploration and clearance can effectively reduce the mortality caused by retropharyngeal lymph node metastasis.

Objective: To investigate the application value of computed tomography (CT) examination of lymph node short diameter in evaluating cardia-left gastric lymph node metastasis in thoracic esophageal squamous cell carcinoma (ESCC). Methods: A total of 477 patients with primary thoracic ESCC who underwent surgical treatment in the Affiliated Cancer Hospital of Zhengzhou University from January 2013 to December 2017 were collected. All of them underwent McKeown esophagectomy plus complete two-field or three-field lymph node dissection. Picture archiving and communication system were used to measure the largest cardia-left gastric lymph node short diameter in preoperative CT images. The postoperative pathological diagnosis results of cardia-left gastric lymph node were used as the gold standard. Receiver operating characteristic (ROC) curve was used to evaluate the efficacy of CT lymph node short diameter in detecting the metastasis of cardia-left gastric lymph node in thoracic ESCC, and determine the optimal cut-off value. Results: The median short diameter of the largest cardia-left gastric lymph node was 4.1 mm in 477 patients, and the largest cardia-left gastric lymph node short diameter was less than 3 mm in 155 cases (32.5%). Sixty-eight patients had cardia-left gastric lymph node metastases, of which 38 had paracardial node metastases and 41 had left gastric node metastases. The lymph node ratios of paracardial node and left gastric node were 4.0% (60/1 511) and 3.3% (62/1 887), respectively. ROC curve analysis showed that the area under the curve of CT lymph node short diameter for evaluating cardia-left gastric lymph node metastasis was 0.941 (95% CI: 0.904-0.977; P<0.05). The optimal cut-off value of CT examination of the cardia-left gastric lymph node short diameter was 6 mm, and the corresponding sensitivity, specificity and accuracy were 85.3%, 91.7%, and 90.8%, respectively. Conclusion: CT examination of lymph node short diameter can be a good evaluation of cardia-left gastric lymph node metastasis in thoracic ESCC, and the optimal cut-off value is 6 mm.

Objective: To examine a predictive model that incorporating high risk pathological factors for the prognosis of stage Ⅰ to Ⅲ colon cancer. Methods: This study retrospectively collected clinicopathological information and survival outcomes of stage Ⅰ~Ⅲ colon cancer patients who underwent curative surgery in 7 tertiary hospitals in China from January 1, 2016 to December 31, 2017. A total of 1 650 patients were enrolled, aged (M(IQR)) 62 (18) years (range: 14 to 100). There were 963 males and 687 females. The median follow-up period was 51 months. The Cox proportional hazardous regression model was utilized to select high-risk pathological factors, establish the nomogram and scoring system. The Bootstrap resampling method was utilized for internal validation of the model, the concordance index (C-index) was used to assess discrimination and calibration curves were presented to assess model calibration. The Kaplan-Meier method was used to plot survival curves after risk grouping, and Cox regression was used to compare disease-free survival between subgroups. Results: Age (HR=1.020, 95%CI: 1.008 to 1.033, P=0.001), T stage (T3:HR=1.995,95%CI:1.062 to 3.750,P=0.032;T4:HR=4.196, 95%CI: 2.188 to 8.045, P<0.01), N stage (N1: HR=1.834, 95%CI: 1.307 to 2.574, P<0.01; N2: HR=3.970, 95%CI: 2.724 to 5.787, P<0.01) and number of lymph nodes examined (≥36: HR=0.438, 95%CI: 0.242 to 0.790, P=0.006) were independently associated with disease-free survival. The C-index of the scoring model (model 1) based on age, T stage, N stage, and dichotomous variables of the lymph nodes examined (<12 and ≥12) was 0.723, and the C-index of the scoring model (model 2) based on age, T stage, N stage, and multi-categorical variables of the lymph nodes examined (<12, 12 to <24, 24 to <36, and ≥36) was 0.726. A scoring system was established based on age, T stage, N stage, and multi-categorical variables of lymph nodes examined, the 3-year DFS of the low-risk (≤1), middle-risk (2 to 4) and high-risk (≥5) group were 96.3% (n=711), 89.0% (n=626) and 71.4% (n=313), respectively. Statistically significant difference was observed among groups (P<0.01). Conclusions: The number of lymph nodes examined was an independent prognostic factor for disease-free survival after curative surgery in patients with stage Ⅰ to Ⅲ colon cancer. Incorporating the number of lymph nodes examined as a multi-categorical variable into the T and N staging system could improve prognostic predictive validity.
