ABSTRACT
RESUMEN Se expone los resultados que sugieren la viabilidad de la ablación con radiofrecuencia (ARF) como una posible estrategia terapéutica efectiva en el caso de una mujer de 56 años con un nódulo tiroideo benigno en lugar de la cirugía tradicional en un Hospital Público del Perú. El seguimiento a los 6 meses reveló una reducción significativa en el tamaño del nódulo y reducción del 70% del volumen; además de mejorar la calidad de vida, mejora en los síntomas y función tiroidea normal. Este caso destaca la evolución en el tratamiento de nódulos tiroideos benignos, con la ARF como una posible opción mínimamente invasiva y segura, la cual se ofrece una alternativa prometedora a las intervenciones quirúrgicas convencionales para el manejo de nódulos tiroideos, marcando un cambio significativo en la práctica clínica, ya que es el primer hospital del MINSA (Ministerio de Salud) en realizar este tipo de procedimientos y que ofrece múltiples enfoques de tratamiento de nódulos tiroideos: ARF, tiroidectomía endoscópica transoral, tiroidectomía convencional y vigilancia activa.
ABSTRACT The results are presented, suggesting the viability of radiofrequency ablation (RFA) as an effective therapeutic strategy in the case of a 56-year-old woman with a benign thyroid nodule instead of traditional surgery at a Public Hospital in Peru. The 6-month follow-up revealed a significant reduction in the size of the nodule and a 70% reduction in volume; in addition to improved quality of life, symptom improvement, and normal thyroid function. This case highlights the evolution in the treatment of benign thyroid nodules, with RFA as a possible minimally invasive and safe option, offering a promising alternative to conventional surgical interventions for the management of thyroid nodules, marking a significant change in clinical practice. This is because it is the first hospital of the MINSA (Ministry of Health) to perform such procedures, offering multiple treatment approaches for thyroid nodules: RFA, transoral endoscopic thyroidectomy, conventional thyroidectomy, and active surveillance.
ABSTRACT
SUMMARY: The objective of this study was to observe the clinical efficacy of apatinib (AP) combined with 131I in the treatment of radioiodine-refractory differentiated thyroid cancer (RAIR-DTC) and the prognostic significance of MIP-1α after treatment, and to provide reference and guidance for future treatment and disease assessment of RAIR-DTC. One hundred and six patients with RAIR- DTC admitted to our hospital from January 2019 to October 2020 were selected for the study. All the patients were treated with TC surgery with 131I at our hospital, and 58 of them were subsequently transferred to AP treatment, which was considered as the research group; the other 48 patients were transferred to thyroid stimulating hormone (TSH) suppression treatment, which was considered as the control group. The clinical efficacy of the research group was better than that of the control group (P 0.05). After treatment, Tg, TL, maximum diameter of C/B lymph nodes, number of lymph nodes and number of calcified spots were lower in the research group than in the control group (P < 0.05). ROC analysis revealed that the predictive sensitivity of MIP-1α for prognosis of 3-year RAIR-DTC death in the research group of patients was 84.63 % and the specificity was 72.16 %. AP combined with 131I is effective in the treatment of RAIR-DTC and is worth using in the clinical practice. In addition, elevated levels of MIP-1α predicted a poor prognosis for patients with RAIR-DTC.
El objetivo de este estudio fue observar la eficacia clínica de apatinib (AP) combinado con 131I en el tratamiento del cáncer de tiroides diferenciado refractario al yodo radiactivo (RAIR-DTC) y la importancia pronóstica de MIP-1α después del tratamiento, y proporcionar referencia y orientación para futuros tratamientos y enfermedades. Evaluación de RAIR- DTC. Se seleccionaron para el estudio 106 pacientes con RAIR- DTC ingresados en nuestro hospital desde enero de 2019 hasta octubre de 2020. Todos los pacientes fueron tratados con cirugía CT con 131I, y 58 de ellos fueron trasladados posteriormente a tratamiento AP, los que fueron considerados como grupo de investigación; los otros 48 pacientes fueron transferidos a tratamiento de supresión de la hormona estimulante de la tiroides (TSH), que se consideró como grupo de control. La eficacia clínica del grupo de investigación fue mejor que la del grupo de control (P 0,05). Después del tratamiento, Tg, TL, diámetro máximo de los linfonodos C/B, número linfonodos y número de manchas calcificadas fueron menores en el grupo de investigación que en el grupo de control (P <0,05). El análisis ROC reveló que la sensibilidad predictiva de MIP-1α para el pronóstico de muerte por RAIR-DTC a 3 años en el grupo de pacientes de investigación fue del 84,63 % y la especificidad fue del 72,16 %. AP combinado con 131I es eficaz en el tratamiento del RAIR-DTC y vale la pena utilizarlo en la práctica clínica. Además, los niveles elevados de MIP-1α predijeron un mal pronóstico para los pacientes con RAIR- DTC.

The objective of this study was to explore the effects and mechanisms of the combination of isobavachalcone (IBC) and doxorubicin (DOX) on the progression of anaplastic thyroid cancer (ATC). Cell viability of 8505C and CAL62 cells was observed by CCK-8 assay. Kits were used to detect the presence of reactive oxygen species (ROS), glutathione (GSH), malondialdehyde (MDA), and cellular iron. Protein expression of solute carrier family 7 member 11 (SLC7A11) and glutathione peroxidase 4 (GPX4) was detected using western blot, and CD31 was detected through immunofluorescence. Tumor xenograft models of 8505C cells were constructed to observe the effect of IBC and DOX on ATC growth in vivo. The co-administration of IBC and DOX exhibited a synergistic effect of suppressing the growth of 8505C and CAL62 cells. The concurrent use of IBC and DOX resulted in elevated iron, ROS, and MDA levels, while reducing GSH levels and protein expression of SLC7A11 and GPX4. However, the Fer-1 ferroptosis inhibitor effectively counteracted this effect. In vitro and in vivo, the inhibitory effect on ATC cell proliferation and tumor growth was significantly enhanced by the combination of IBC and DOX. The combination of IBC and DOX can inhibit the growth of ATC by activating ferroptosis, and might prove to be a potent chemotherapy protocol for addressing ATC.

ABSTRACT
OBJECTIVE To investigate the diagnostic efficacy of serum calcitonin(Ctn)in medullary thyroid cancer(MTC),the correlation between preoperative serum Ctn and clinicopathological features,and the risk factors affecting the progression of MTC disease during follow-up.METHODS The clinical data of 50 patients admitted to the Hospital of Integrated Traditional Chinese and Western Medicine of Nanjing University of Chinese Medicine from 2011 to 2022 were systematically reviewed,the ROC curve calculated the diagnostic efficacy of Ctn and CEA levels on MTC,and the risk factors for lymph node metastasis in the central region of MTC were analyzed in univariate and multivariate,and the survival curve without disease progression was drawn to predict risk factors.RESULTS The ROC curve yields the preoperative cut-off value of Ctn was 23.81 pg/ml and the cut-off value of CEA was 3.035 ng/ml for the diagnosis of MTC.The age of disease,tumor diameter,and preoperative serum Ctn and CEA levels in MTC patients were higher than those in non-MTC patients.Ctn≥289.62 pg/ml was an independent risk factor for central lymph node metastasis in MTC.The survival curve showed that invasion of the capsule,central region metastasis,and TNM stage above T2 were risk factors for predicting disease progression(P<0.05).Patients with MTC who have disease progression have higher preoperative Ctn.CONCLUSION Serum Ctn has important clinical value in the differential diagnosis,preoperative evaluation and postoperative follow-up of MTC.
ABSTRACT
OBJECTIVE To compare the metabolomic characteristics of stage T1 papillary thyroid carcinoma(PTC)and nodular goiter(NG),and the relationship between metabolites and lymph node metastasis of PTC.METHODS Serum samples were collected from 60 patients with stage T1 PTC and 30 patients with NG who underwent thyroidectomy at the Department of Otolaryngology Head and Neck Surgery,Civil Aviation General Hospital between September 2021 and April 2022.The PTC group was divided into the N+ group with lymph node metastasis and the N-group without lymph node metastasis according to the presence or absence of lymph node metastasis.The serum metabolites of the N+ and N-groups and the PTC and NG groups were compared and analyzed using an ultra-performance liquid chromatography-mass spectrometry(UPLC-Q-Exactive-MS)coupled platform,and principal component analysis(PCA),partial least squares discriminant analysis(PLS-DA),and orthogonal partial least squares discriminant analysis(OPLS-DA)was performed using SIMCA-P 14.1 software.OPLS-DA modeling,combined with FDR-corrected Mann-Whitney-Wilcoxon test results and metabolite difference multiples in the two groups undergoing comparison,etc.to screen for potential small molecule metabolic markers,and to establish a joint diagnostic model by binary logistic regression analysis.RESULTS There were no significant differential metabolites between the N+ group with lymph node metastasis and the N-group without lymph node metastasis.Seven differential metabolites were found between PCA patients and NG patients,and the five relevant metabolic pathways were the pentose phosphate pathway,pentose and glucuronide interconversion,glycolysis/gluconeogenesis,fructose,and mannose metabolism,and fatty acid biosynthesis.The differential metabolite with an area under the ROC curve>0.9 was D-glyceraldehyde 3-phosphate,and another N-undecanoylglycine,uronic acid,and the area under the ROC curve for three metabolites,N-undecanoylglycine,uric acid,and triiodothyronine glucuronide,was>0.8.CONCLUSION PTC patients differed from NG patients mainly in glucose metabolism and lipid metabolism,and D-glyceraldehyde 3-phosphate could be distinguished from NG patients with the aid of N-undecanoylglycine,uric acid,and triiodothyronine glucuronide,combined with imaging findings.Also,no significant differences in serum metabolites were found in the N+ group compared with the N-group,and the presence or absence of lymph node metastases did not affect serum metabolites in patients with stage T1 PTC.
ABSTRACT
Objective To investigate the relationship between circKIF4A expression and clinicopathologic features and prognosis of thyroid cancer patients.Methods A total of 120 patients diagnosed with thyroid cancer in our hospital from April 2016 to April 2017 were selected by random sampling method.Cancer tissues and adjacent tissues were taken during surgery and divided into thyroid cancer group and adjacent cancer group according to surgical pathologic detection.The relative expression level of circKIF4A in thyroid cancer group and paracancer group was detected by qRT-PCR,and the relationship between circKIF4A expression and clini-copathological features of thyroid cancer was analyzed.Kaplan-Meier survival curve was used to analyze the relationship between circKIF4A expression and prognosis of thyroid cancer patients.Cox regression analysis was performed to analyze the factors influencing the poor prognosis of patients with thyroid cancer 5 years af-ter surgery.Results The relative expression level of circKIF4A in thyroid cancer group was higher than that in paracancer group,and the difference was statistically significant(P<0.05).The expression of circKIF4A was correlated with the degree of capsule invasion,lymph node metastasis and differentiation(P<0.05).Kap-lan-Meier survival curve analysis showed that the 5-year cumulative survival rate of patients with high cir-cKIF4A expression was lower than those with low circKIF4A expression,and the difference was statistically significant(x2=11.368,P=0.001).Multivariate analysis showed that envelope invasion,degree of differenti-ation,lymph node metastasis and circKIF4A expression level were the influencing factors for poor prognosis of thyroid cancer patients at 5 years after surgery(P<0.05).Conclusion circKIF4A is highly expressed in thy-roid cancer tissues,which is related to the clinicopathological features and 5-year postoperative survival of thy-roid cancer patients,and may be used as a potential prognostic marker for thyroid cancer.
ABSTRACT
Objective To systematically evaluate the clinical efficacy of the prescriptions for softening hardness to dissipate mass combined with Levothyroxine Sodium in the treatment of postoperative thyroid cancer,and to provide evidence-based medical proof for clinical treatment of postoperative thyroid cancer.Methods Computer search was performed in the major domestic and oversea databases for the retrieval of clinical randomized controlled trials(RCTs)of prescriptions for softening hardness to dissipate mass combined with Levothyroxine Sodium for the treatment of postoperative thyroid cancer.After screening the literature according to the inclusion and exclusion criteria,the quality of the included literature was evaluated using the tools for analysis of the bias recommended by Cochrane Reviewer's Handbook and the modified JADAD rating scale,and meta-analysis was performed using RevMan 5.4 software.Results A total of 11 RCTs involving 749 patients were eventually included.The results of meta-analysis showed that compared with Levothyroxine Sodium alone,prescriptions for softening hardness to dissipate mass combined with Levothyroxine Sodium significantly enhanced the efficacy of postoperative patients with thyroid cancer(RR=1.30,95%CI[1.21,1.41],Z = 6.81,P<0.000 01),and improved the thyroid functions parameters of serum thyroid stimulating hormone(TSH)(SMD=-1.75,95%CI[-2.38,-1.13],Z = 5.47,P<0.000 01),thyroglobulin(TG)(SMD=-1.13,95%CI[-1.71,-0.55],Z = 3.81,P = 0.000 1),free triiodothyronine(FT3)(SMD=3.42,95%CI[0.73,6.10],Z = 2.50,P = 0.01),free thyroxine(FT4)(SMD=1.85,95%CI[0.05,3.66],Z = 2.02,P = 0.04),and thyroglobulin antibody(TgAb)(SMD=-0.63,95%CI[-1.11,-0.15],Z = 2.55,P = 0.01),increased Karnofsky Performance Status(KPS)scores(SMD= 2.19,95%CI[1.30,3.08],Z = 4.81,P<0.000 01),shortened the time for the relief of clinical symptoms after thyroid cancer surgery(MD=-4.67,95%CI[-5.38,-3.96],Z = 12.87,P<0.000 01),reduced the diameter of the largest thyroid nodule after thyroid cancer surgery(MD=-2.51,95%CI[-3.13,-1.89],Z = 7.94,P<0.000 01),regulated the immune function indicators of T lymphocyte population CD3+(MD=8.68,95%CI[4.97,12.39],Z = 4.59,P<0.000 01)and CD4+(MD=10.77,95%CI[5.46,16.08],Z = 3.97,P<0.000 1)levels,and reduced the incidence of postoperative complications of thyroid cancer(RR=0.34,95%CI[0.18,0.65],Z = 3.26,P = 0.001).The differences were all statistically significant(P<0.05).Conclusion prescriptions for softening hardness to dissipate mass combined with Levothyroxine Sodium can enhance the efficacy of postoperative patients with thyroid cancer.The combined therapy is superior to Levothyroxine Sodium alone in improving thyroid function indicators,KPS score,time for the relief of clinical symptoms,diameter of the largest thyroid nodule,immune function indicators,and the incidence of postoperative complications.However,due to the small amount of included trials and the fact that the prescriptions for softening hardness to dissipate mass vary in the composition,the conclusions of the analysis need to be confirmed by more high-quality,multi-center,large-sample clinically randomized controlled trials.
ABSTRACT
Objective:To research the efficacy and safety of robotic thyroidectomy and bilateral modified radical neck dissection through bilateral axillo-breast approach (BABA) .Methods:We retrospectively analyzed the clinical data of 37 patients with thyroid cancer who received bilateral modified radical neck dissection through the BABA at the Department of Thyroid and Breast Surgery of the 960th Hospital of the People’s Liberation Army from Jan. 2014 to Jan. 2023. There were 24 females and 13 males, and the average age of the patients was (33,22±10.53) years old. The tumor diameter, number of lymph node dissection and metastasis in the central and lateral regions, average operation time, average hospital stay, complications, and aesthetic score were recorded. SPSS 25.0 software was used for statistical analysis, and the measurement data was calculated using mean ± standard deviation ( ± s), and the counting data was expressed in percentages and numbers. Results:A total of 37 thyroid cancer patients underwent robotic bilateral regional lymph node dissection. The 37 patients received total thyroidectomy, bilateral central compartment and cervical lateral regional lymph node dissection. All the pathological types were papillary carcinoma, with a maximal tumor diameter of (1.47±0.85) cm. The average number of central lymph nodes dissected was 19.46±8.84, and there were (10.24±5.95) metastases; The average number of lymph nodes removed from the bilateral cervical region was 38.92±14.21, and there were (7.92±5.84) metastases. The average operation time was (288.05±77.09) min, the average length of stay in the hospital was (10.76±3.92) days, and the average length of stay in the hospital following surgery was (8.03±2.08) days. These patients had no permanent hypoparathyroidism, permanent recurrent laryngeal nerve palsy, infection, accessory nerve injury and phrenic nerve injury after operation. Transient hypoparathyroidism occurred in 15 patients, transient recurrent laryngeal nerve palsy occurred in 1 patient, and chyle leak occurred in 2 patients. One month after surgery, the aesthetic score was 9.51±0.69.Two patients were found lymph node metastases during the (27.81±15.10) months of follow-up, and received robotic cervical lymph node dissection with BABA.Conclusion:For carefully chosen thyroid cancer patients with bilateral lateral cervical region lymph node metastases, robotic bilateral cervical lymph node regional dissection via BABA is safe and feasible, and good cosmetic results can be obtained.
ABSTRACT
Objective:To compare the surgical outcomes between scarless endoscopic thyroidectomy-lateral neck dissection (SET-LND) and open LND for papillary thyroid cancer (PTC) with lymph node metastasis and to share the experience in the prevention and treatment of lymphatic leakage after LND.Methods:Totally 90 PTC patients (25 males) who underwent LND in the Second Affiliated Hospital of Zhejiang University School of Medicine from Jan. 2021 to Aug. 2022 were retrospectively enrolled, with an average age of (28.06±4.89) years. They were divided into the SET-LND group ( n=50) and the open LND group ( n=40). The intraoperative blood loss, operation time, drainage volume on the first and the second days, postoperative lymphatic leakage, tumor (T), and node (N) were observed. The categorical variable data were compared between groups by χ 2 test, and the continuous variable data confirming normal distribution were compared between groups by independent sample t-test. Results:The operation time of the SET-LND group was (284.00±74.65) min, significantly longer than that of the open LND group (145.38±43.26) min ( t=-10.42, P<0.001). The intraoperative blood loss ( t=-1.309, P=0.194), postoperative hospital stay ( t=-0.136, P=0.892), drainage volume on the first day ( t=-1.074, P=0.286), and drainage volume on the second day ( t=-1.595, P=0.114), postoperative lymphatic leakage ( χ2=0.001, P=0.989), T ( t=0.367, P=0.714), N ( t=-1.614, P=0.110) were not significantly different between the two groups. Conclusion:Two surgical methods of LND have similar therapeutic effects and no significant difference was observed in the incidence of postoperative lymphatic leakage between the two groups.
ABSTRACT
Objective:To analyze the effectiveness of radioactive iodine (RAI) treatment for papillary thyroid cancer (PTC) with an intermediate and high risk of recurrence.Methods:The clinical data of 709 cases of PTC, comprising 226 men and 483 women, who underwent surgical treatment for thyroid cancer at Xiangya Hospital of Central South University from Oct. 2010 to Jan. 2020 were retrospectively analyzed. According to whether RAI treatment was performed after initial surgery or not, they were divided into a RAI group (253 cases with intermediate risk and 209 cases with high risk) and a non-RAI group (147 cases with intermediate risk and 100 cases with high risk), and the relationship between RAI treatment and clinicopathological characteristics such as sex, age, and tumor size for intermediate- and high-risk PTC was analyzed by χ2 test or Fisher’s exact test and Logistic regression analysis. The Kaplan-Meier method was used to calculate the recurrence-free survival rate. Results:The treatment rate of intermediate-risk PTC RAI was 63.25% (253/400) and that of high-risk PTC RAI was 67.64% (209/309). Univariate analysis of intermediate-risk PTC showed that age, bilateral tumors, lymph node metastasis stage, number of lymph node metastases, and intermediate-risk PTC RAI treatment were closely related (all P values <0.05). Multi-factor regression analysis of intermediate-risk PTC showed that age ≥ 55 ( OR=0.282, P=0.005), lymph node metastasis stage N1b ( OR=19.245, P<0.001), and the number of lymph node metastases ≤ 5 ( OR=0.322, P<0.001) were independent predictors of RAI treatment for intermediate-risk PTC (all P values < 0.05). The recurrence-free survival curve for intermediate-risk PTC showed a lower recurrence-free survival rate in the RAI group than in the non-RAI group, but the difference was borderline significant ( P=0.049). Univariate analysis of high-risk PTC showed that age, multifocal tumors, bilateral tumors, lymph node metastasis stage, number of lymph node metastases and high-risk PTC RAI treatment were strongly associated (all P values <0.05). Multifactorial regression analysis for high-risk PTC showed that age ≥ 55 ( OR=0.382, P=0.020), bilateral tumors ( OR=2.173, P=0.030), lymph node metastasis stage N1b ( OR=11.215, P<0.001), and the number of lymph node metastases ≤5 ( OR=0.389, P=0.004) were independent predictors of RAI treatment for high-risk PTC patients (all P values <0.05). The recurrence-free survival curve for high-risk PTC showed a lower recurrence-free survival rate in the RAI group than in the non-RAI group, however, the difference was not statistically significant ( P=0.07) . Conclusions:No significant benefit was observed with RAI treatment for intermediate- and high-risk PTC and rigorous screening of eligible patients is recommended.
ABSTRACT
Objective:To analyze the risk factors for central lymph node metastasis (CLNM) in patients with papillary thyroid cancer (PTC) aged 55 years and above, and to construct a predictive model with columnar graph.Methods:This retrospective study included 406 PTC patients aged 55 and above, treated at the First Affiliated Hospital of Zhengzhou University from Nov. 2019 to Feb. 2022. Data on demographic characteristics, disease features, and laboratory test results were collected. Univariate and multivariate logistic regression analyses were used to identify risk factors for CLNM and develop a clinical prediction model and nomogram.Results:The study involved 406 patients, divided into a modeling group (285 patients) and a validation group (121 patients). The predictive model identified independent risk factors for CLNM. In the modeling group, the model demonstrated a ROC AUC of 0.769, with 82.6% sensitivity, 63.0% specificity, and 67.7% accuracy. The validation group showed 66.7% sensitivity, 74.5% specificity, and 72.7% accuracy, with an AUC of 0.760. Hosmer-Lemeshow tests indicated good fit in both groups. Decision curve analysis confirmed the model's clinical decision-making value, showing better performance than traditional strategies and good generalizability and reliability.Conclusions:Sex, maximum tumor diameter, bilateral involvement of thyroid lobes, clinically evident cervical lymph nodes, and local invasion are independent predictive factors for CLNM in patients over 55 with papillary thyroid carcinoma (PTC). A clinical risk stratification nomogram model based on these risk factors demonstrates good predictive performance.
ABSTRACT
Objective:To analyze and compare the pathological data characteristics of patients with simple papillary thyroid carcinoma (PTC) and PTC combined with Hashimoto’s thyroiditis (HT), so as to provide clinical treatment ideas.Methods:A retrospective analysis was performed on the medical records of 326 PTC patients who met the requirements and underwent surgical treatment in the Department of Thyroid and Breast Surgery, Nanjing Hospital of Traditional Chinese Medicine from Jan. 2020 to May. 2022. There were 81 males and 245 females. They were divided into PTC group and HT-PTC group, according to whether they were combined with HT. Clinical data were collected and organized. The collection indicators included patient gender, age, body mass index (BMI), five preoperative thyroid function items including free triiodothyronine (FT3), free thyroxine (FT4), triiodothyronine (T3), thyroxine (T4), thyroid stimulating hormone (TSH), BRAF gene mutation, single or bilateral lesions, single or multiple lesions, largest postoperative pathological tumor lesions diameter, cervical lymph node metastasis (LNM) status, etc. At the same time, all patients were divided into CLNM group and no CLNM group according to CLNM status. The two groups were compared in terms of gender, age ≥55 years old, whether combined with HT, number of lesions, unilateral and bilateral, extraglandular invasion, microcarcinoma, and BRAF gene. Statistical software was used to analyze the results. t test, χ2 test, and logistic regression analysis were adopted. P<0.05 indicates that the difference is statistically significant. Results:The proportion of female patients in both groups was higher, and the proportion of female patients in the HT-PTC group (90/100, 90%) was higher than that in the PTC group (155/226, 69.59%). HT-PTC patients were younger than patients in the PTC group (43.03±12.72 vs. 43.70±12.63) years old, and their TSH (2.71±1.69 vs. 2.02±1.46) uIU/mL was higher. The differences were statistically significant (all P<0.05). There were no statistically significant differences in BMI, FT3, FT4, T3, or T4 (all P>0.05). The HT-PTC group had a lower proportion of BRAF gene mutations [87/100 (87%) vs. 212/226 (93.8%) ], a smaller maximum tumor diameter (1.06±0.73 vs. 1.32±0.97 cm), and a lower proportion of CLNM [37 /100 (37%) vs. 118/226 (52.2%) ]. The number of LNMs with metastasis is less (3.33±2.21 vs. 4.76±4.00), and it was more likely to be multifocal [44/100 (44%) vs. 73/226 (32.74%) ]. All differences were statistically significant (all P<0.05), and the differences in bilateral gland lobes involvement and extra-glandular invasion were not statistically significant. When accompanied by CLNM, gender (male vs. female) [55/100 (35.45%/64.52%) vs. 26/145 (15.2%/84.85%) ], age ≥ 55 years (yes vs. no) [21/134 (13.55) %/86.45%) vs. 50/121 (29.24%/70.76%) ], HT (yes vs. no) [37/118 (23.87%/76.13%) vs. 63/108 (36.84%/63.16%), number of lesions (single focus vs. multiple focus) [90/65 (41.94%/50.06%) vs. 119/52 (69.59%/30.41%) ], microcarcinoma (yes vs. no) [83/72 (53.55%/45.45%) vs. 139/32 (81.29%/18.71%) ] and extraglandular invasion (with vs. without) [38/117 (24.52%/75.48%) vs. 27/144 (17.42%/84.21%) ] had statistics significance (both P<0.05). There was no statistical significance in bilateral lesion involvement or BRAF gene mutation (all P>0.05). Multivariate logistic regression analysis showed that age, microcarcinoma, HT, gender, and number of lesions were independent risk factors for CLNM, and male gender and multifocal cancer were risk factors for CLNM. Age ≥55 years, microcarcinoma, and combined HT were negatively associated with CLNM. Conclusions:HT may promote the occurrence of PTC, but can inhibit its development. In the short term, patients with HT can have a better prognosis than those with simple PTC.
ABSTRACT
Objective:To investigate the safety and efficacy of pseudomonas aeruginosa Injection (PAI) in the treatment of coeliac leakage after cervical lymph node dissection for robotic thyroid cancer.Methods:Retrospective analysis of 1262 patients who underwent robotic thyroid surgery at the 960th Hospital of the People’s Liberation Army from Jan. 2021 to Aug. 2023 was made. Postoperative celiac leakage happened in 28 patients. The control and injection groups were divided according to whether pseudomonas aeruginosa injection was used or not. In the control group, there were 4 males and 11 females out of 15 patients, with an average age of (46.20±9.02) years old, and the treatment methods of low-fat diet, negative pressure suction, and pressure bandage were used. In the injection group, there were 7 males and 6 females among 13 patients, with an average age of (41.00±8.87) years. They were treated with low-fat diet, negative pressure suction, pressure bandage, and PAI .The number of lymph node dissection, total drainage volume, peak drainage volume, days of hospitalization and the rate of decline in drainage volume within 24 h after the use of PAI in the injection group, post-injection temperature, number of injections, and post-injection extubation time were statistically analyzed in both groups. Independent samples t test, Mann-Whitney U test, χ2 test or Fisher’s exact test were used for comparison between groups. Results:There was no statistically significant difference in age, gender, extent of thyroidectomy, highest daily drainage volume, and total drainage volume between the two groups ( P>0.05). The difference in the number of lymph node dissection (49.15±23.05 vs. 30.80±11.76, P=0.012) and hospitalization time (11.77±4.64 vs. 16.40±6.42, P=0.041) between the injection group and the control group was statistically significant. After the use of pseudomonas aeruginosa injection, the draining fluid decreased from the previous day (69.56± 20.82) % in the injection group; Twelve patients were successfully extubated after one injection of pseudomonas aeruginosa injection, and one patient was successfully extubated after two injections; the mean time to extubation after injection was (3.85±1.28) days; 76.9% patients (10/13) had fever symptoms within 48 h with body temperature (38.05±0.89) ℃ after injection, body temperature returned to normal after symptomatic treatment,and no other adverse reactions occurred except fever. Conclusion:Pseudomonas aeruginosa injection is safe and effective in the treatment of celiac leakage after cervical lymph node dissection for robotic thyroid cancer, effectively reducing cervical drainage and shortening hospitalization days.

Objective:To establish a nomogram model based on elastic imaging parameters and ultrasound image features, and evaluate its predictive value in central lymph node metastasis (CLNM) in papillary thyroid carcinoma (PTC) .Methods:The clinical data of 168 patients (the research group) with papillary thyroid carcinoma who underwent thyroid surgery in our hospital from Jan. 2019 to Dec. 2021 were retrospectively collected, including gender, age, ultrasound elastography parameters (elasticity ratio, blue area ratio), and ultrasound examination indicators (nodule diameter, nodule number, internal echo, border, edge, aspect ratio, microcalcification, capsule invasion). Another 150 patients who underwent thyroid surgery in our hospital during the same period were selected as the validation group.According to the results of postoperative pathological examination, the the research group were divided into two groups: 64 cases (38.10%) of CLNM and 104 cases (61.90%) of non-CLNM. Binary logistic regression analysis was used to explore the influencing factors of CLNM in PTC patients, and a nomogram model based on elastic imaging parameters and ultrasound image features was established. The nomogram model was drawn to predict the receiver operating characteristic (ROC) curve of CLNM in PTC patients.Results:There were statistically significant differences in nodule diameter, edge, microcalcification, capsule invasion, blue area ratio, and elasticity ratio ( P<0.05). Most of the nodules in the CLNM group were ≥10 mm in diameter, with uneven margins, an aspect ratio of <1, microcalcifications and capsular invasion. Logistic regression analysis showed that nodule diameter, capsule invasion, blue area ratio and elastic ratio were risk factors for CLNM ( P<0.05). The AUC of the combined detection was 0.857 (0.777-0.937), and the sensitivity and specificity were 78.1% and 86.5%, respectively, and the AUC and sensitivity were significantly higher than the individual detection of each index ( P<0.05). In the research group, the sensitivity and specificity of the ultrasound parameter prediction model in predicting CLNM were 81.25% (52/64) and 84.62% (88/104), respectively. In the validation group, the sensitivity and specificity of the ultrasound parameter prediction model in predicting CLNM were 79.17% (38/48) and 85.29% (87/102), respectively. Conclusion:Elastography parameters (blue area ratio, elasticity ratio) and ultrasound image features (nodule diameter, capsular invasion) are the influencing factors of CLNM in PTC patients, and the combined prediction based on the above four indicators has good application value.
ABSTRACT
Objective To investigate the expression of discoidin CUB and LCCL domain containing 2(DCBLD2)and mitogen activated protein kinase kinase kinase kinase 3(MAP4K3)in thyroid cancer and their relationship with clinico-pathological features and prognosis.Methods A total of 92 patients with thyroid cancer diagnosed and treated in Xinghua People's Hospital Affiliated to Yangzhou University from January 2016 to June 2020 were selected.Immunohistochemistry(IHC)was used to detect the expression of DCBLD2 and MAP4K3 in thyroid cancer tissues and adjacent tissues.The expression differences of DCBLD2 and MAP4K3 in thyroid cancer patients with different clinicopathological features were compared.Kaplan-Meier curve analysis was used to analyze differences in the progression-free survival prognosis of patients with different DCBLD2 and MAP4K3 expressions.Multivariate COX analysis was used to analyze the risk factors affecting the progression-free survival prognosis of thyroid cancer.Results The positive rates of DCBLD2(67.39%)and MAP4K3(65.22%)in thyroid cancer tissues were higher than those in adjacent tissues(5.43%,6.52%),and the differences were statistically significant(χ2=76.262,68.894,all P<0.05).The expression of DCBLD2 was positively correlated with MAP4K3(r=0.742,P<0.001).The positive rates of DCBLD2 and MAP4K3 in stage Ⅲ~Ⅳ(87.18%,84.62%)and lymph node metastatic cancer tissues(93.75%,90.63%)were higher than those in stage Ⅰ~Ⅱ(52.83%,50.94%)and non lymph node metastatic cancer tissues(53.33%,51.67%),with statistically significant differences(χ2=11.230~15.513,all P<0.05).The 3-year progression-free survival rates of DCBLD2-positive and DCBLD2-negative patients were 74.19%(46/62)and 93.33%(28/30),respectively.The 3-year progression-free survival rates of MAP4K3 positive and negative patients were 75.00%(45/60)and 90.63%(29/32),respectively.The 3-year cumulative progression-free survival rate of DCBLD2 positive group and MAP4K3 positive group was lower than that of DCBLD2 negative group and MAP4K3 negative group,and the differences were statistically significant(χ2=4.533,4.138,P=0.033,0.046).DCBLD2 positive(OR=1.659,P=0.001),MAP4K3 positive(OR=1.606,P=0.001),tumor TNM stage Ⅲ~Ⅳ(OR=1.766,P=0.001)and combined lymph node metastasis(OR=1.868,P=0.001)were independent risk factors for the progression-free survival prognosis of thyroid cancer patients.Conclusion The expressions of DCBLD2 and MAP4K3 were increased in thyroid cancer tissue.They are involved in the occurrence and development of thyroid cancer,which may help evaluate the progression-free survival prognosis of thyroid cancer patients.
ABSTRACT
Objective To investigate the factors affecting the number of lymph nodes obtained by unilateral lobectomy and isthmus combined with prophylactic ipsilateral central lymph node dissection for papillary thyroid cancer,and to analyze the pattern of change so as to provide an important basis for clinical treatment of papillary thyroid cancer.Methods Retrospective analysis was performed on the clinical and pathological data of 193 patients admitted to the department of Thyroid Surgery of the First Affiliated Hospital of Jinzhou Medical University from January 2019 to January 2022 for papillary thyroid cancer who underwent unilateral glandular lobe and isthmus resec-tion combined with prophylactic ipsilateral central lymph node dissection.The number of obtained lymph nodes was divided into a group with high number of obtained lymph nodes(n>6)and a group with low number of obtained lymph nodes(n≤6).Univariate analysis and multivariate analysis were used to explore the factors affecting the num-ber of obtained lymph nodes.The influence of the number of lymph nodes on the central lymph node metastasis was evaluated by correlation analysis,and the influence of the number of lymph nodes on the quality of life of patients by postoperative complications analysis.Results The number of lymph nodes obtained was positively correlated with the number of lymph node metastases in the central region(r = 0.240,P<0.05)and the rate of lymph node metastasis(r = 0.161,P<0.05),respectively.The number of lymph node metastases controlled remained unchanged,and the rate of lymph node metastasis decreased with the increase of the number of obtained lymph nodes(r =-0.444,P<0.05).Univariate analysis of the number of lymph nodes between the two groups showed no significant differences in terms of sex,age,operation duration,BMI,maximum tumor diameter,multifocality,Hashimoto's thyroiditis,focal location,capsular invasion,contralateral thyroid nodule,parathyroid transplantation and BRAF gene V600E mutation(P>0.05).There was statistical significance in the application of nano carbon between the two groups(P<0.05).Logistic binary regression analysis showed that the combination of Hashimoto's thyroiditis and the application of carbon nanoparticles were independent influencing factors for the high number of lymph nodes obtained(P<0.05).ROC curve analysis suggested that the area under the curve occupied by carbon nanoscale was 0.658(95%CI:0.580~0.735,P<0.05),and the area under the curve occupied by Hashimoto's thyroiditis was 0.584(95%CI:0.504~0.665,P<0.05).In addition,there was no significant difference in the incidence of vocal cord paralysis and lymphatic leakage between the two groups(P>0.05).Conclusions When the number of lymph nodes in the cen-tral region remained unchanged,the higher the number of lymph nodes obtained,the lower the rate of lymph node metastasis.The application of nano-carbon and patients with Hashimoto's thyroiditis could increase the number of lymph nodes obtained,and there is no significant difference in the incidence of postoperative complications between high and low number of lymph nodes obtained.
ABSTRACT
In the past decade,thyroid surgery in China has developed rapidly.With the improvement of thyroid diagnosis technology,the standardization of thyroid surgery,the clinical application of systematic therapy,and the progress in fundamental research,thyroid surgery has achieved all-round development.Patients with thyroid disease have benefited significantly from safer,more standardized,more effective,and more diverse treatments,which results in the remarkable increase in the 5-year survival rate.Moreover,Chinese experts have published a number of guidelines and expert consensus related to thyroid surgery,which promotes the standardization of the diagnosis and treatment of thyroid disease.Additionally,the specialized multidisciplinary teams in cancer centers allow patients to receive more standardized diagnosis and treatment of complex thyroid diseases.In the present article,we summarize the important developments of China's thyroid surgery in the past decade,including preoperative diagnosis technology,surgical methods,operation safety,application of minimally invasive techniques,diagnosis and treatment of special thyroid cancers,multidisciplinary diagnosis and treatment models,and standardized postoperative managements.We expect to popularize the concept of standardized diagnosis and treatment of thyroid diseases,and improve the level of standardized diagnosis and treatment in thyroid surgery.
ABSTRACT
Differentiated thyroid cancer usually has a good prognosis;however,recurrence occurs in 5%to 20%of patients after initial treatment,which causes physiopsychological and financial burdens for the patients.In the meantime,it complicates the treatment decision-making for clinicians.Different from initial treatment,the management of recurrent thyroid cancer should take comprehensive consideration of factors such as risks and benefits.Surgery is considered to be the first choice of treatment while radioactive iodine therapy is recommended for radioiodine-avid recurrent disease.Smaller lesions can be managed with active surveillance temporarily,and thermal ablation should only be applied to patients not suitable for additional surgery.In contrast,external beam radiotherapy and systemic therapies are considered only after all therapy options have been exhausted.
ABSTRACT
Surgical resection is the standard treatment for most patients with thyroid cancer(TC)and is of critical significance for the prognosis of TC.However,clarifying the surgical indications of TC,standardizing the surgical method of TC and formulating rational and personalized treatment strategies are the key to maximizing the curative effect of surgical treatment.In recent years,the global consensus on guidelines related to TC diagnosis and treatment has been rapidly updated,and comprehensive guidelines covering the whole course of the disease and suitable for China's national conditions are urgently needed to keep pace with the times.In this context,the Chinese Anti-Cancer Association(CACA)'s first guidelines for the diagnosis and treatment of thyroid cancer covering all pathologic types,"Chinese Guidelines for the Integrated Diagnosis and Treatment of Cancer-CACA Guidelines for the Diagnosis and Treatment of Thyroid Cancer,"(short as 2022 edition of CACA guidelines)was officially released in April 2022.Based on the authors'personal clinical experience,this paper will interpret the contents of the 2022 edition of CACA guidelines from differentiated TC(DTC)diagnosis,initial treatment and postoperative follow-up from a surgical perspective,explore the particularity and value of surgical treatment strategies in the entire management of TC diagnosis and treatment,and point out areas that deserve to be explored in the future.
