RESUMO

Introduction and aim: Although percutaneous ethanol sclerotherapy for the treatment of benign thyroid nodules (PEI) has been used for more than 30 years, there are only two studies in thyroid cysts (THCY) and 2 in autonomously functioning nodule (AFN) in which the mean follow-up reaches at least five years, while in the event of non-autonomously functioning solid nodules (NAS), there is not any study with at least 5-year mean follow-up. Our study focuses on the long-term efficacy of PEI in benign thyroid nodules. Method: We analyzed the long-term success of PEI in 254 patients treated for more than 10 years. The success was defined as 50% or greater reduction in nodule volume. In addition, the patient had to remain euthyroid without thyrostatic therapy in AFN. Results: The 10-year success rate was 79.4%, 37.1% and 69.4% in THCY, AFN and NAS, respectively. In 23.3% of unsuccessful PEIs, the failure could be revealed only after 5 years of follow-up. The mean nodule volume at 10-year follow-up related to the initial size was 29.8%, 39.6% and 48.9% in THCY, NAS and AFN, respectively. In THCY, PEI proved to be significantly more effective in older patients while other parameters (size of the nodule, amount of the injected alcohol and the ratio of these) did not correlate significantly with the success rate. Conclusions: Our study which presents the longest follow-up in all 3 types of benign thyroid nodules confirms that PEI has a minimal role in AFN, is recommendable in THCY and might have a role in NAS. The success rate decreases over time which emphasizes the importance of the long-term follow-up in the judgement of PEI. Orv Hetil. 2020; 161(6): 224-231.

RESUMO

The risk of malignancy is considered to be 10% to 30% for cases of thyroid nodules with atypia or follicular lesion of undetermined significance (AUS/FLUS). However, only a minority of patients with AUS/FLUS undergo surgery; therefore, the risk of malignancy might be overestimated due to selection bias. To overcome this problem, we categorized cases of thyroid nodules with AUS/FLUS using the ultrasound risk stratification system (US-RSS) to calculate the malignancy rate and identify the patients most suitable for surgical treatment.In this retrospective observational study, we subcategorized 382 pathologically confirmed thyroid nodules with AUS/FLUS using current US-RSSs (American Thyroid Association, Korean-Thyroid Imaging Report and Data System, American College of Radiology-Thyroid Imaging, Reporting and Data System, European Thyroid Imaging Report and Data System) and calculated the malignancy rate. Additionally, cases of nodules with AUS/FLUS were categorized according to their cytological subtypes, and the malignancy rate was calculated.Current US-RSSs showed good or moderate agreement among them. The overall malignancy rate for thyroid nodules with AUS/FLUS was 38.7%. On categorization of the nodules with AUS/FLUS, the malignancy rates were found to be 60% to 67.5% for the high suspicion category, 32.2-36.6% for the intermediate suspicion category, and 12.4% to 16.3% for the low suspicion category. The malignancy rate for nodules with cytologic atypia was significantly higher than that for nodules with architectural atypia, especially in the intermediate suspicion category.Categorization of thyroid nodules with AUS/FLUS using current US-RSSs helps to determine the optimal course of management of patients, especially when combined with cytological subtype characterization.

RESUMO

The authors present the case of a multiplex endocrine neoplasia type 2A (MEN2A). The 55-year-old woman underwent detailed examinations for abdominal complaints. Bilateral adrenal masses and thyroid nodular goiter were found. Based on metanephrine excretion and MIBG imaging, bilateral phaeochromocytomas were diagnosed. The thyroid nodules were confirmed by thyroidectomy as bilateral medullary thyroid carcinoma. Asymptomatic primary hyperparathyroidism was also detected. Laparoscopic adrenalectomy and parathyroid adenoma removal were performed. Based on family history and the characteristic clinical presentation, MEN2A syndrome was confirmed by genetic testing. During genetic screening of first-degree relatives, the patient's 25-year-old daughter was shown to be a gene carrier. Preventive thyroidectomy was performed and histology proved multifocal medullary thyroid cancer. In addition to the importance of genetic testing, the authors emphasize the guideline-based, but individualized approach to patients with suspected MEN2A syndrome. Orv Hetil. 2020; 161(2): 75-79.

RESUMO

Thyroid nodules are extremely common and can be detected by sensitive imaging in more than 60% of the general population. They are often identified in patients without symptoms who are undergoing evaluation for other medical complaints. Indiscriminate evaluation of thyroid nodules with thyroid biopsy could cause a harmful epidemic of diagnoses of thyroid cancer, but inadequate selection of thyroid nodules for biopsy can lead to missed diagnoses of clinically relevant thyroid cancer. Recent clinical guidelines advocate a more conservative approach in the evaluation of thyroid nodules based on risk assessment for thyroid cancer, as determined by clinical and ultrasound features to guide the need for biopsy. Moreover, newer evidence suggests that for patients with indeterminate thyroid biopsy results, a combined assessment including the initial ultrasound risk stratification or other ancillary testing (molecular markers, second opinion on thyroid cytology) can further clarify the risk of thyroid cancer and the management strategies. This review summarizes the clinical importance of adequate evaluation of thyroid nodules, focuses on the clinical evidence for diagnostic tests that can clarify the risk of thyroid cancer, and highlights the importance of considering the patient's values and preferences when deciding on management strategies in the setting of uncertainty about the risk of thyroid cancer.

RESUMO

Ancillary molecular testing has emerged as a promising way to refine the preoperative risk stratification of thyroid nodules with indeterminate fine needle aspiration (FNA) biopsy results. Commercially available molecular tests for thyroid FNAs include those that analyze samples for mutations and gene fusions, gene expression alterations, microRNA expression alterations, chromosomal copy number alterations, or a combination thereof. This review summarizes the performance characteristics of the most current iterations of three tests currently marketed for cytologically indeterminate thyroid nodules: ThyroSeq v3, ThyGeNEXT/ThyraMIR, and Afirma Gene Sequencing Classifier.

RESUMO

BACKGROUND: Chronic lymphocytic thyroiditis (CLT) increases cytologic atypia on fine-needle aspiration of thyroid nodules, and its effect on rate of malignancy in atypia of undetermined significance (AUS)/follicular lesions of undetermined significance (FLUS) thyroid nodules remains unclear. This study evaluates the effect of concomitant CLT on malignancy rates of AUS/FLUS thyroid nodules in surgical patients. METHODS: Retrospective review of 1061 patients who underwent thyroidectomy for a dominant thyroid nodule from a single institution was performed. Fine-needle aspiration was classified according to the Bethesda System for Reporting Thyroid Cytopathology. Patients with AUS/FLUS cytopathology were classified into two cohorts: AUS/FLUS with CLT and AUS/FLUS without CLT. Final pathology was reviewed, and the cohorts were further stratified into benign and malignant subgroups. When applicable, patients with gene expression classifier (GEC) testing were reviewed and the positive predictive value (PPV) was calculated. RESULTS: Of the entire surgical series, 293 (28%) patients had AUS/FLUS cytopathology with a rate of malignancy of 56% (163/293) on final pathology. Seventy-three (25%) patients had AUS/FLUS with CLT, of which 44% (n = 32) were malignant by final pathology. The remaining 75% (n = 220) had AUS/FLUS without CLT, 60% (n = 131) of which were malignant. GEC testing was performed in 36 of the AUS/FLUS with CLT patients, where of the 33 suspicious results, 17 were malignant on final pathology, yielding a PPV of 52%. CONCLUSIONS: The rate of malignancy for AUS/FLUS thyroid nodules is lower with coexisting CLT, and similar to previous studies, the PPV of GEC testing is approximately 50%. Cytologic atypia due to CLT may increase more AUS/FLUS results in thyroid nodules, which may lead to overestimation of malignancy rates in this patient population.

RESUMO

INTRODUCTION: The diagnostic performance of ultrasound-fine needle aspiration to identify thyroid nodules harbouring malignancy remains variable. The aim of this study was to determine thyroid nodule size and cytological classification as predictors of malignancy risk. MATERIALS AND METHODS: We conducted a retrospective cohort analysis at an academic hospital involving 499 consecutive patients who underwent thyroid surgery between 2004 and 2015. RESULTS: A total of 503 thyroid nodules (499 patients, 84% female; mean age 50.8 years, standard deviation, SD, 15.4 years) were analysed. Of these, 19.5% were malignant. The mean (± SD) nodule size was 3.28 ± 1.63 cm and 3.27 ± 1.54 cm for benign and malignant nodules, respectively. The odds of malignancy for thyroid nodules less than 3.0 cm was similar to those for nodules of 3.0 cm or greater (0.26 compared with 0.29; p=0.77). Overall, the sensitivity and specificity of fine-needle aspiration in this cohort were 71.4% and 100%, respectively. The overall false negative rate was 5.4%. When the cut-off of 3.0 cm was used, the false negative rate in thyroid nodules less than 3.0 cm was 0% compared with 7.0% in nodules of 3.0 cm or greater. Thus, class (p<0.01) but not nodule size (p=0.49), was associated with higher malignancy risk. CONCLUSIONS: Our results suggest that thyroid nodule size did not accurately predict the risk of thyroid malignancy irrespective of fine-needle aspiration cytology. Routine diagnostic thyroid lobectomy solely owing to thyroid nodule size of 3.0 cm or greater is currently not justified.

RESUMO

OBJECTIVE: To analyze own initial experience of transoral thyroid surgery. MATERIAL AND METHODS: There were 7 patients thyroid nodules who underwent surgery for the period from March 2018 to May 2019. All patients signed an informed consent to be included in the study. Surgical approach was performed through three incisions in the lower arch of the vestibule of the mouth with deployment of 10 mm endoscope and two 5 mm tools. Gas insufflation was used. All patients were females aged 43.3±11.8 years. Thyroidectomy was performed in 2 cases, hemithyroidectomy - in 5 patients. Dimensions of nodules varied from 10 to 42 mm. RESULTS: Mean time of hemithyroidectomy and thyroidectomy was 206.4±63.8 and 232±37.5 min, respectively. Papillary carcinoma was histologically verified in 1 case. Injuries of recurrent laryngeal nerve, postoperative hypocalcemia and local complications were absent. Drainage was not applied. Postoperative hospital-stay was 3.7±1.1 days. CONCLUSION: Transoral approach to the thyroid gland is technically feasible with standard endoscopic instruments, safe for important anatomical structures and more precise due to the optical capabilities of endoscopic equipment. Any types of procedures are possible. Undoubtedly, aesthetic outcome is also favorable.

RESUMO

Thyroid nodules are a very common problem whose prevalence increases with age. When treatment is considered, surgical excision is traditionally the first choice, except in the case of hyperfunctioning nodules, where treatment with radioactive iodine plays a major role. In recent years, there has been increasing experience in the thermal ablation of thyroid nodules by radiofrequency, with very encouraging results. This article aims to discuss the role of radiofrequency thermal ablation in the management of benign thyroid nodules by reviewing the indications, adverse effects and limitations of this method.

RESUMO

OBJECTIVE: We aimed to investigate the value of the combined use of high-resolution ultrasound thyroid imaging reporting and data system (TI-RADS) classification and thyroid fine needle aspiration cytology (Bethesda classification) for the qualitative diagnosis of benign and malignant thyroid nodules. METHODS: We enrolled 295 patients with 327 thyroid nodules who were scheduled to undergo thyroid nodule surgery. Before surgery, all the patients underwent ultrasound and scoring with the TI-RADS classification, along with thyroid fine needle biopsy cytology under ultrasound guidance (US-FNAC) and scoring with the Bethesda classification. After surgery, the TI-RADS and Bethesda classification scores, separately and in combination, were compared with the postoperative pathological results in terms of the differential diagnosis of thyroid nodules. RESULTS: TI-RADS classification score 4 exhibited the highest diagnostic value for thyroid cancer; the sensitivity, specificity, and accuracy were 92.7%, 70.7%, and 87.1%, respectively, whereas the Kappa and receiver-operating characteristics (ROC) values were 0.651 and 0.817, respectively. Moreover, Bethesda classification score 3 exhibited the highest diagnostic value for thyroid cancer; the sensitivity, specificity, and accuracy were 90.0%, 94.3%, and 91.1%, respectively, whereas the Kappa and ROC values were 0.78 and 0.914, respectively. With regard to the combined diagnostic method, a score of 7 exhibited the highest diagnostic value for thyroid cancer; the sensitivity, specificity, and accuracy were 97.3%, 92.0%, and 95.9%, respectively, whereas the Kappa and ROC values were 0.893 and 0.946, respectively. CONCLUSION: The combination of high-resolution ultrasonography TI-RADS classification and US-FNAC (Bethesda classification) can improve the accuracy of malignant thyroid nodules diagnosis.

RESUMO

This study aimed to investigate the application of the healthcare failure mode and effect analysis (HFMEA) to reduce the incidence of posture syndrome of thyroid surgery (PSTS).Subjects before (n = 78, July 2017-December 2017) and after (n = 114, January 2018-June 2018) HFMEA implementation (The Second Hospital of Nanjing, Nanjing University of Chinese Medicine) were selected. The training for PSTS was optimized using HFMEA.The occurrence of PSTS was reduced from 59% to 18% after HFMEA (P < .001). Symptoms of pain and nausea and vomiting were also decreased after HFMEA (all P < .001). The critical thinking ability of 34 medical personnel to evaluate the reduction of thyroid postoperative posture syndrome increased from 246 ±â€Š19 to 301 ±â€Š14 (P < .001) after HFMEA.HFMEA was used to create preoperative posture training procedures for PSTS, bedside cards for training, innovative preoperative posture training equipment, and a diversified preoperative posture training health education model.

RESUMO

OBJECTIVE: To summarize and evaluate the value of applying the thyroid imaging reporting and data system (TI-RADS) released by American College of Radiology (ACR) in 2017 of the thyroid classification, and to propose an optimized classification method based on the result to facilitate more accurate and precise risk stratification of thyroid nodules. METHODS: In the study, 342 thyroid nodules assessed by 2017 ACR TI-RADS were retrospectively analyzed. Each nodule had a score, and all the scores of nodules were compared with the pathological results. The proportion of malignant nodules in different scoring ranges was obtained. The diagnostic efficacy of all nodules, nodules above 1 cm and less than or equal to 1 cm was evaluated by ROC curve, respectively. RESULTS: The AUC of all nodules, nodules above 1 cm and less than or equal to 1 cm were 0.907, 0.936 and 0.717, respectively. With the increase of the scores, the proportion of benign nodules decreased gradually, and the proportion of malignant nodules increased, especially nodules of 4-6 scores increased significantly. Based on the proportion of malignant nodules with 3 scores, the proportion of malignant nodules with 4, 5 and 6 scores increased 1.6, 3.8 and 5.3 times, respectively. The proportion of malignant nodules with 6-8 scores was 81%-84%, while the proportion of malignant nodules with 9 scores or more was 93%-94%. According to the distribution characteristics of malignant nodules, the classification of TI-RADS was adjusted. TI-RADS 4 was divided into TI-RADS 4a, TI-RADS 4b and TI-RADS 4c, corresponding to 4, 5 and 6-8 scores respectively, while the nodules with 9 scores or more were divided into TI-RADS 5. CONCLUSION: 2017 ACR TI-RADS has high diagnostic value for thyroid nodules above 1 cm, but it is not so effective for the nodules less than or equal to 1 cm. According to the proportion distribution of malignant nodules in different scoring ranges, appropriate adjustment of classification will be more accurate and precisely predict the malignant risk of nodules.

RESUMO

For a long time, the diagnosis and treatment of pediatric thyroid nodules and cancer (PTNC) are mainly referred to adults. In recent years, it has been found that there are great differences between PTNC and TNC in adults. In 2015, the American Thyroid Association released the first Management Guidelines for Children with Thyroid Nodules and Differentiated Thyroid Cancer. In the guidelines, the characteristics of PTNC were described, and clear management strategies were provided. In this paper, we mainly interpret the surgical part of the guidelines and also review the associated research progress in recent years.

RESUMO

Objective: To study common problems in BRAF gene mutation detection, and conditions for repetition testing using thyroid fine needle aspiration specimens. Methods: A total of 8 644 cases of thyroid fine-needle aspiration specimens at China-Japan Friendship Hospital were collected between February, 2012 and July, 2018. BRAF gene mutation was detected by real-time PCR. Repeat testing was performed in 237 cases when the results were inconsistent with clinical or cytological diagnosis or when uncertain results were obtained. Results: The final positive rates of BRAF mutation was 22.0% (1 897/8 625). Nineteen cases were excluded due to inadequate DNA samples. The average Ct value of internal quality control was 16.061, and the average Ct value of the positive samples was 19.147. Among 237 repeat tests, 51.4% (19/37) continued to have poor DNA quality and 48.6% (18/37) had adequate DNA resulting in 1 positive case and 17 negative cases. In 40 repetition of initial negative cases, results were unchanged. In initial positive cases, 40.4% (40/99) with a difference of Ct value (between BRAF gene and internal quality control) between 8 to 12 turned negative after repetition, 69.8% (37/53) of these cases with a difference of more than 12 turned negative after repetition. The sensitivity and specificity of BRAF mutation were 83.97% and 96.94%, respectively. Conclusions: Difference between BRAF gene Ct value and internal quality control Ct value is recommended as a reliability index for the test result. Cases with a difference greater than 8 should be subjected to repeat testing.

RESUMO

We investigated whether laryngoscopy should be performed before total thyroidectomy on all patients without a history of neck surgery. A total of 2523 patients who underwent total thyroidectomy between January 1, 2013, and March 18, 2018, were retrospectively examined. Preoperative vocal cord examination was performed on 2070 of these patients by the otorhinolaryngology department using indirect laryngoscopy. Patients with a history of neck or thyroid surgery were not included in the study. The patients were evaluated in terms of age, gender, symptom (hoarseness/dyspnea), comorbidity, surgical history, biopsy, nodule diameter, pathological diagnosis, and tracheal deviation. Preoperative vocal cord paralysis was detected in 0.8 per cent of the patients (17/2070). Four patients (23.5%) were male and 13 patients (76.5%) were female. The mean age was 62 (range, 25-82) years. Seven of the 17 patients (41%) were symptomatic, with complaints of dyspnea in five and hoarseness in two. The univariate analysis revealed that a nodule diameter >30 mm and the presence of dyspnea were associated with vocal cord damage. Furthermore, the multivariate analysis showed that dyspnea alone was an independent variable (P = 0.011). It is recommended that preoperative vocal cord evaluation should be performed only in patients with severe symptoms, such as dyspnea.

Objective To compare the predictive value of different ratio measurement in predicting the risk of malignant thyroid nodules and to determine the best value of ratio in diagnosing thyroid nodules.Methods The clinical data of 342 thyroid nodules diagnosed by ultrasonography and confirmed by histology in our hospital from January 2018 to August 2018 were analyzed.The ratio of nodules in different sections,including longitudinal plane ratio(A/TL)and transverse plane ratio(A/TC),was obtained through the maximum head-foot diameter(TL),the maximum left-right diameter(TC),and the anterior-posterior diameter(A)of transverse section measured by ultrasonography.The correlation of histological diagnosis of benign or malignant nodule with longitudinal ratio and transverse ratio were analyzed.Results The A/TC and A/TL of malignant nodules were 1.00(0.83,1.17)and 0.81(0.65,1.00),respectively,which were significantly higher than those of benign nodules [0.81(0.67,0.93)(Z=-6.567,P=0.000)and 0.63(0.52,0.75)(Z=-7.239,P=0.000)].The area under the ROC curve of A/TC and A/TL was 0.734 and 0.712,respectively,showing no significant difference(area difference:0.0210,standard error:0.0213,95% CI:-0.0207-0.0627,Z=0.987,P=0.3235).The threshold values of A/TC and A/TL for predicting malignant nodules were 0.784 161 5 and 0.985 714 5,respectively.Conclusions Both A/TL and A/TC has similar diagnostic value in predicting the risk of malignant nodules.The best cutoff value of the above two ratios are 0.78 and 0.99 respectively.

RESUMO

BACKGROUND: Advances in diagnostic methods have led to an early detection of thyroid nodules with debatable malignant potential in numerous cases. This can result in a potential overtreatment of thyroid lesions with very good prognosis. OBJECTIVES: To avoid surgical overtreatment, an individualized, risk-adapted management is required that respects the different tumor biology of the underlying histological entities. METHODS: The current guidelines of the leading professional societies, the American Thyroid Association (ATA) and the German Association of Endocrine Surgeons (CAEK), were compared and critically studied, to describe risk-adapted, more conservative treatment options for certain types of thyroid neoplasms according to the 2017 WHO definition. RESULTS: The German CAEK recommends thyroidectomy as a routine operation in the case of thyroid carcinoma. Exceptions are papillary thyroid microcarcinoma and minimally invasive follicular thyroid carcinoma, which can be treated by lobectomy. The ATA proposes an "active surveillance" for papillary thyroid microcarcinoma and lobectomy in cases of differentiated thyroid carcinoma <4 cm in diameter in the absence of clearly predefined risk factors. CONCLUSIONS: The pre- or intraoperative pathological diagnosis of the underlying tumor entity is the key point, which allows for an adaption of the resection strategy for thyroid malignancy. Depending on the type of carcinoma, the current guidelines of international expert societies allow for parenchyma-sparing operations and, according to the ATA, even an "active surveillance."

RESUMO

INTRODUCTION: The mean prevalence of thyroid nodules in adults is about 20% and increases with age. Most of the thyroid nodules are benign, and are rarely malignant. However, malignancy can often only be conclusively determined after resection. Therefore, it is essential that the surgical technique should be free of complications. Despite all published minimally invasive techniques, the open procedure via a Kocher incision is still standard and commonly used in a teaching setting. This standardised technique is presented step-by-step in the video. INDICATION: Sonographic and MIBI-scintigraphic possibly malignant solitary node in the right thyroid lobe. PROCEDURE: Hemithyreoidectomy with neuromonitoring of recurrent laryngeal nerve. CONCLUSION: Hemithyroidectomy is an adequate primary therapy for a solitary possibly malignant thyroid nodule. Intraoperative neuromonitoring to identify and protect the recurrent laryngeal nerve, visualisation and protection of the parathyroid glands without compromising blood circulation and careful hemostasis are the main pillars of low risk surgery of the thyroid.

RESUMO

OBJECTIVE: To study the clinical application value of ultrasound-guided fine needle aspiration biopsy (US-FNAB) and contrast-enhanced ultrasound (CEU) in the diagnosis of thyroid imaging reported and data system Grade 4 (TI-RADS 4) nodules.
 Methods: A retrospective analysis of 134 patients with thyroid nodules surgery were selected, and their results of preoperative color Doppler ultrasonography were TI-RADS 4. The data of US-FNAB and CEU before operation and the results of pathological section after operation were collected. The pathological results were taken as the gold standard, and the specimens obtained by US-FNAB puncture were used for HE staining and cytological diagnosis. The sensitivity, specificity, accuracy and the cost were calculated for CEU and US-FNAB, respectively. The diagnostic efficacy of the 2 methods was compared.
 Results: Of 134 thyroid nodules, there were 131 malignant nodules (97.76%) and 3 benign ones (2.24%). The sensitivity of US-FNAB and CEU were 87.02% and 93.89% respectively. The specificity of US-FNAB and CEU were 100.00% and 66.67%. The accuracy of US-FNAB and CEU were 87.31% and 93.28% respectively. Comparisons of the diagnostic accuracy were performed by χ2 test. There was no significant difference in sensitivity between CEU and US-FNAB (P>0.05). However, the sensitivity of US-FNAB and CEU were 87.50% and 100.00%, respectively, when the maximum diameter of nodule was less than 10 mm, and there was statistical significance (P<0.05). The sensitivity of US-FNAB and CEU were 92.73% and 85.45%, respectively, when the maximum diameter of nodule was more than 10 mm, and there was no statistical significance (P>0.05). The cost and risk of US-FNAB was higher than those of CEU.
 Conclusion: The sensitivity of US-FNAB is higher than that of CEU for thyroid nodules with the diameter larger than 10 mm. With high detection rate, good safety and low cost, CEU can still be used for thyroid nodules with the diameter less than 10 mm, which is diagnosed as negative nodules by US-FNAB.
