Objective To investigate the clinical effect of non inflatable endoscope assisted lateral cervical lymph node dissection in elderly patients with thyroid cancer. Methods The clinical data of 61 patients with lateral cervical lymphadenectomy assisted by non inflatable endoscope from January 2016 to December 2020 were retrospectively summarized. There were 48 females and 13 males with an average age of (71±6.5) years (range, 65–82 years). The operative time, intraoperative blood loss, cases of accessory nerve injury, cases of phrenic nerve injury, total number of lateral neck dissection lymph nodes, postoperative lymphatic leakage, postoperative drainage volume and hospital stay were counted. Neck ultrasonography and thyroglobulin levels were measured during follow-up to assess recurrence. Results All patients successfully completed the non inflatable endoscopic assisted lateral cervical lymph node dissection, the operative time was 51–117 min, the average was (92±22.1) min, the intraoperative blood loss was about 80–150 mL, the average was (120±17.1) mL, the postoperative drainage was 190–670 mL, the average was (332±167.1) mL, the postoperative hospital stay was 5–13 d, the average was (9±2.3) d, the total number of lymph nodes was 11–23, the average was (16±4.7). There were 11 cases of hypoparathyroidism, 5 cases of temporary recurrent laryngeal nerve injury, 3 cases of accessory nerve injury and no case of phrenic nerve injury. One patient had local redness and swelling after removing the drainage tube. Lymphatic leakage occurred in 3 cases. There was no recurrence during the follow-up period. Conclusion Non inflatable endoscope assisted lateral neck lymph node dissection provides technical support for elderly patients with thyroid cancer, and the effect is exact, and the short and medium-term follow-up results are satisfactory.
ObjectiveTo understand the follow-up needs of postoperative patients with thyroid cancer and analyze its influencing factors, so as to provide a reference for the establishment of a follow-up management system for patients with thyroid cancer.MethodsConvenience sampling was used to conduct a questionnaire survey on the follow-up need, recovery, anxiety, and stress of patients after thyroid cancer surgery in 2 tertiary A hospitals from March to April in 2020. The self-designed follow-up needs questionnaire, the Quality of Recovery Questionnaire 15 (QoR-15), the Generalized Anxiety Disorder-7 (GAD-7), and the Perceived Stress Scale (PSS-4) were scored. The higher score, the higher need, the better recovery, and the more serious anxiety and stress.ResultsIn this study, 382 questionnaires were distributed, which of 351 were returned and of 349 were valid, the valid callback rate was 99.4% (349/351). ① Follow-up needs. Follow-up form: Online platform was the preferred follow-up method (72.2%), the most patients hoped that the follow-up would be conducted by a doctor (82.5%) and hoped to start the follow-up at 1 month after the operation (67.6%) and in the afternoon (50.7%), the duration of each follow-up was 10–15 min (47.3%), and accepted the follow-up frequency of 1 times per month (41.3%) and the lifetime follow-up (69.9%). Needs degree of follow-up contents: There were 13 follow-up items requiring more than 80% of patients. The top 5 items with the higher follow-up needs score were the question on test results, returning visit guidance, knowledges of metastasis and recurrence, medication guidance, and issuance of inspection orders, and their scores were 4.78±0.47, 4.70±0.51, 4.70±0.57, 4.65±0.59, 4.57±0.64, respectively. The results of multiple linear regression analysis were found that the age (young), marital status (unmarried), medical payment method (with medical insurance), and postoperative interval (<1 month) were closely related to the follow-up needs score (P<0.05). ② Recovery, anxiety, and stress statuses: The total QoR-15 score of patients was 79.87±29.95, which was positively correlated with the total score of follow-up needs (72.93±8.52, r=0.131, P=0.014). No significant correlation was found between the total score of GAD-7 (4.77±3.59) or PSS-4 (6.51±3.10) and the total score of follow-up needs (r=0.068, P=0.207; r=0.008, P=0.881).ConclusionsYoung, unmarried, medically insured, and early postoperative patients with thyroid cancer have higher follow-up needs. Patients with better recovery after surgery have a higher follow-up needs. Medical staff should pay attention to follow-up services after discharge, rationally arrange content, frequency, and time period of follow-up according to follow-up needs of patients, so as to improve quality of medical services.
ObjectiveTo analyze the influencing factors of fear of cancer recurrence (FCR) and its correlation with social support and quality of life in patients with differentiated thyroid cancer (DTC) at 5 years after surgery. MethodsA total of 116 patients with DTC from West China Hospital, Sichuan University at 5 years after surgery were selected as the research objects. The patients were investigated using the Fear of Progression Questionnaire-Short Form (FoP-Q-SF), Social Support Rating Scale (SSRS) and the European Organization for Reasearch and Treatment of Cancer Quality of Life Questionnare-Core 30 (EORTC QLQ-C30, hereinafter referred to as QLQ-C30). The χ2 test or Fisher exact probability method were used for univariate analysis, and multivariate logistic regression analysis was used for influencing factor analysis. The diagnostic value of variables with significant influence on FCR in multivariate logistic regression was further studied by receiver operating characteristic (ROC) curve, and Pearson correlation analysis was finally adopted to analyze the relationship between FCR and social support and quality of life in patients with DTC at 5 years after operation. ResultsThe questionnaire survey showed that the FoP-Q-SF score of 116 patients with DTC at 5 years after surgery was (35.92±2.52) scores, of which 75 patients had FoP-Q-SF score ≥34 scores, 41 patients had FoP-Q-SF score <34 scores, and the FCR rate was 64.66% (75/116). Multivariate logistic regression showed that gender, family annual income, SSRS score and total QLQ-C30 score were the main factors of FCR in patients with DTC at 5 years after surgery (P<0.05). Further ROC curve diagnosis showed that the accuracy rate of diagnosis of FCR with SSRS score ≤47.5 scores was 70.70%, the total score of QLQ-C30 ≤617.225 scores was 69.02%. The accuracy rate of diagnosis of FCR was 66.03% when the annual income of family was less than 150 000 yuan. The accuracy of women’s diagnosis of FCR was 62.28%. Pearson correlation analysis showed that FoP-Q-SF score was negatively correlated with SSRS score and total score of QLQ-C30 in DTC patients at 5 years after operation (r=–0.629 6, P=0.000 1; r=–0.568 5, P=0.000 1). ConclusionsThe proportion of patients who have FCR at 5 years after DTC operation is high, and gender, family annual income, SSRS score and total score of QLQ-C30 are the influencing factors. Therefore, we can develop targeted management strategies to reduce patients’ FCR and improve their quality of life.
Objective To investigate the role of preoperative serum thyroid stimulating hormone (TSH) in evaluating differentiated thyroid cancer (DTC). Methods A total of 551 patients with thyroid nodules met the study criteria, who got treatment in the First Affiliated Hospital of Jiamusi University between Aug. 2017 and Dec. 2017. And the patients were divided into DTC group (n=110) and benign group (n=441) according to the postoperative pathological results. The difference of serum TSH level between the 2 groups was compared and then explored the diagnostic significance of serum TSH level, thyroid imaging report and data system (TI-RADS), and serum TSH combined withTI-RADS. Results The serum TSH level was higher in the DTC group than that of the benign group (Z=5.198, P<0.05). The sensitivity of preoperative serum TSH level in the diagnosis of DTC was 80.9% (89/110), the specificity was 74.4% (328/441), and the area under receiver operating characteristic (ROC) curve was 0.660 ［95%CI was (0.602, 0.719), P<0.05］. The sensitivity of TI-RADS in the diagnosis of DTC was 82.7% (91/110), the specificity was 73.5% (324/441), and the area under the ROC curve was 0.772 ［95%CI was (0.711, 0.823), P<0.05］. The sensitivity of preoperative serum TSH combined with TI-RADS in the diagnosis of DTC was 91.8% (101/110), the specificity was 87.5% (386/441), and the area under the ROC curve was 0.831 ［95%CI was (0.786, 0.876), P<0.05］. Conclusions Preoperative serum TSH level may be a potential risk factor for the occurrence of DTC. Preoperative serum TSH level combined with TI-RADS classification can improve the accuracy of preoperative diagnosis of DTC, not only to reduce the misdiagnosis of thyroid cancer, but also can avoid excessive treatment.
ObjectiveTo understand the role of calcitonin testing for the diagnosis and treatment of medullary thyroid cancer (MTC) as well as recent research progress, so as to provide assistance in the early clinical diagnosis and treatment of MTC and improve patients’ prognosis. MethodThe literatures about the role of calcitonin testing in MTC in recent years were reviewed. ResultsIn recent years, both domestic and international scholars had extensively investigated the role of calcitonin in the early detection of MTC and accurate postoperative prognosis assessment. With respect to early diagnosis, advancements had been made in the three main measurement methods: basal calcitonin, stimulated calcitonin, and calcitonin measurement in the thyroid nodule fine-needle aspiration washout fluid. These developments in calcitonin levels had contributed to improved guidance in surgical treatment and prognosis evaluation. While calcitonin monitoring could inform treatment decisions and improve patients’prognosis, numerous challenges remain to be addressed. ConclusionThe study of calcitonin detection can deepen the understanding of MTC, further research on calcitonin related detection in the future will be of great significance for the diagnosis, treatment and prognosis evaluation of MTC.
Objective To explore the expression of matrix metalloproteinase （MMP）-2 in patients with papillary thyroid cancer （PTC） recurrence or residuum and its value of clinical application. Methods The serums from 68 patients with thyroid disease underwent operation and 15 health examinations under stomachs empty from March 2009 to December2009 in this hospital were gathered. Sixty-eight patients with thyroid disease were divided into PTC with lymph node metastasis （LNM） group （n=19），PTC recurrence or residuum with LNM group （n=17），PTC without LNM group （n=10），and benign thyroid disease group （n=22） according to the postoperative pathological findings，15 health examinations as control group. The expression of MMP-2 of serum sample was detected by ELISA method. The difference of the expression of MMP-2 in each group was analyzed. Results The expressions of MMP-2 in the PTC recurrence or residuum with LNM group，PTC with LNM group，PTC without LNM group， benign thyroid disease group，and the control group were （1 724.00±762.24） ng/ml，（1 329.16±776.59） ng/ml，（1 489.61±546.53） ng/ml，（1 264.87±817.27） ng/ml，and （608.43±88.63） ng/ml，respectively. The expressions of MMP-2 in the PTC with LNM group and PTC recurrence or residuum with LNM group were significantly higher than those in the benign thyroid disease group （P＜0.05） and the control group （P＜0.05），respectively，which in the PTC without LNM group was significantly higher than that in the control group （P＜0.05）. There was no significant difference of MMP-2 expression of serum between the benign thyroid disease group and the control group （P＞0.05），which were no significant difference among the other threemalignant disease groups （P＞0.05）. The MMP-2 positive expression rates were 79%，76%，80%，41%，and 20% in the PTC with LNM，PTC recurrence or residue with LNM group，PTC without LNM group，benign thyroid disease group，and control group，respectively. The MMP-2 positive expressions rates of serums were not significantly different among three malignant disease groups （P＞0.05），but which were significantly higher than those of the benign thyroid disease group （P＜0.01） and control group （P＜0.01），respectively. Conclusions The MMP-2 level of serum can be used as an index to judge preoperative thyroid nodules，which can not be use to determine whether PTC metastasis or not.
【Abstract】ObjectiveTo study the antitumor effects of DNA electrotransfer in muscle (ETM) by using established animal model for human anaplastic thyroid cancer cell line TA-K.MethodsNude mice with implanted TA-K were divided into five groups including: control group, pcDNA-3 plasmid electrotransfered into muscle (pcDNA ETM group), TIMP-3 plasmid injected into muscle (TIMP-3 IM group), TIMP-3 plasmid electrotransfered into muscle (TIMP-3 ETM group), TIMP-3 plasmid electrotransfered into implanted tumor (TIMP-3 ETT group). Electrical parameters used in electrotransfer were: 200 V/cm, 20 ms/pulse; 8 pulses, 1 Hz in muscle and 600 V/cm, 20 ms/pulse; 1 pulses, 1 Hz in implanted tumor respectively. ResultsThe growth of TA-K was inhibited more significantly in the groups of TIMP-3 plasmid electrotransfered into muscle and TIMP-3 plasmid electrotransfered into implanted tumor than the other groups (P＜0.05), and the content of TIMP-3 protein in tumor tissues was higher in these two groups . ConclusionAnti-oncogene has the antitumor effects by DNA electrotransfer in muscle.
ObjectiveTo summarize the clinicopathological characteristics of papillary thyroid cancer (PTC) in adolescents and analyze the risk factors affecting lateral lymph node metastasis and prognosis. MethodsIn retrospectively, 150 adolescent PTC patients admitted to the Department of Thyroid Surgery of the First Affiliated Hospital of Zhengzhou University from January 2012 to January 2022 and meeting the inclusion and exclusion criterias were collected as the study subjects (adolescent group), and 100 adult PTC patients were selected as adult group. Statistical analysis was performed with SPSS 25.0 software to compare the clinicopathological characteristics of the patients in the two groups, and to explore the risk factors for lateral lymph node metastasis and recurrence in adolescent PTC patients by using logistic regression and Cox proportional hazards regression models, respectively. ResultsAdolescents with PTC were more prone to extrandular invasion [30.0% (45/150) versus 17.0% (17/100), P=0.020], neck lymph node metastasis [79.3% (119/150) versus 48.0% (48/100), P<0.001], central lymph node metastasis [78.7% (118/150) versus 48.0% (48/100), P<0.001], lateral lymph node metastasis [44.0% (66/150) versus 12.0% (12/100), P<0.001]; and had a greater maximum tumor diameter (1.75 cm versus 0.75 cm, P＜0.001) and higher ratio of greater maximum tumor diameter ＞2 cm [45.3% (68/150) versus 8.0% (8/100), P＜0.001] in adolescent PTC patients. In adolescent PTC patients, extraglandular invasion (OR=2.654, P=0.022), multifoci (OR=4.860, P<0.001) and maximum tumor diameter>2 cm (OR=3.845, P=0.001) were risk factors for lateral lymph node metastasis; lateral lymph node metastasis (RR=10.105, P=0.040) and distant metastasis (RR=7.058, P=0.003) were predictors of postoperative recurrence in adolescent PTC patients. ConclusionsCompared with adult PTC patients, adolescent PTC patients have more aggressive tumors. Adolescent PTC with extraglandular invasion, multilesions, and maximum tumor diameter>2 cm should be considered for lateral lymph node dissection; and adolescent PTC patients with lateral lymph node metastasis and distant metastasis should pay close attention to their recurrence status.
Objective To summarize the advance in targeted therapy for radioactive iodine-refractory differentiated thyroid cancer (RAIR-DTC). Method The literatures relevant to the targeted therapy for RAIR-DTC were reviewed and summarized. Results Targeted therapy for RAIR-DTC mainly included multi-kinase inhibitors suppressing angiogenesis and mutation-specific kinase inhibitors targeting specific mutations. Representative multi-kinase inhibitors such as sorafenib and lenvatinib, which significantly prolonged progression-free survival, had been approved to put into clinical use, though there were shortcomings such as adverse effects and resistance. Mutation-specific kinase inhibitors acted on targets such as RET, mitogen-activated protein kinase pathway, phosphoinositide 3-kinase pathway respectively, with relatively small side effects, most of which had only been applied in clinical trials up to now. Conclusions Targeted therapy for RAIR-DTC has made rapid progress in recent years, filling the gap in treatment for RAIR-DTC. Further explorations and investigations are needed to establish a more effect and safer treatment mode.
ObjectiveTo explore the application value of carbon nanoparticles during radical operation of differentiated thyroid cancer (DTC).MethodsThe DTC patients underwent total thyroidectomy plus neck lymph node (area Ⅳ) dissection from September 2017 to September 2019 in this hospital were retrospectively collected, who were divided into observation group and control group according to using carbon nanoparticles or not during the operation. The operation related informations [operation time, intraoperative blood loss, total drainage volume on day 3 after operation, postoperative hospitalization time, number of lymph nodes dissection (area Ⅳ), lymph node metastasis rate, and rate of parathyroid glands resected by mistake during operation] and blood calcium (Ca2+) level and parathyroid hormone (PTH) level before and after (24 h and 1 month) operation were compared between the two groups.ResultsA total of 134 patients with DTC were collected, including 76 patients in the observation group and 58 patients in the control group. There were no significant differences in baseline data such as gender, age, etc. between the two groups (P>0.05). Although there were no significant differences in terms of operation time, intraoperative blood loss, total drainage volume on day 3 after operation, postoperative hospitalization time, lymph node metastasis rate between the two groups (P>0.05), the numbers of lymph node dissection and metastasis (area Ⅳ) were more and rate of parathyroid glands resected by mistake during operation was lower in the observation group as compared with the control group (P<0.05). On hour 24 after operation, the levels of Ca2+ and PTH in the observation group were higher than those in the control group (P<0.05). On month 1 after operation, the PTH level in the observation group was still higher than that in the control group (P<0.05), but there was no significant difference in Ca2+ level between the two groups (P>0.05). ConclusionCarbon nanoparticles can better protect the function of parathyroid gland during radical operation of DTC and clean neck lymph nodes more thoroughly.
