Abstract
Given the high incidence and excellent prognosis of many papillary thyroid microcarcinomas, the Porto proposal uses the designation papillary microtumor (PMT) for papillary microcarcinomas (PMCs) without risk factors to minimize overtreatment and patients' stress. To validate Porto proposal criteria, we examined a series of 190 PMC series, also studying sex hormone receptors and BRAF mutation. Our updated Porto proposal (uPp) reclassifies as PMT incidental PMCs found at thyroidectomy lacking the following criteria: (a) detected under the age of 19 years; (b) with multiple tumors measuring >1 cm adding up all diameters; and (c) with aggressive morphologic features (extrathyroidal extension, angioinvasion, tall, and/or hobnail cells). PMCs not fulfilling uPp criteria were considered "true" PMCs. A total of 102 PMCs were subclassified as PMT, 88 as PMC, with no age or sex differences between subgroups. Total thyroidectomy and iodine-131 therapy were significantly more common in PMC. After a median follow-up of 9.6 years, lymph node metastases, distant metastases, and mortality were only found in the PMC subgroup. No subgroup differences were found in calcifications or desmoplasia. Expression of estrogen receptor-α and estrogen receptor-β, progesterone receptor, and androgen receptor was higher in PMC than in nontumorous thyroid tissue. BRAF mutations were detected in 44.7% of PMC, with no differences between subgroups. In surgical specimens, the uPp is a safe pathology tool to identify those PMC with extremely low malignant potential. This terminology could reduce psychological stress associated with cancer diagnosis, avoid overtreatment, and be incorporated into daily pathologic practice.

Completion Total Thyroidectomy Is Not Necessary for Papillary Thyroid Microcarcinoma with Occult Central Lymph Node Metastasis: A Long-Term Serial Follow-Up. Cancers (Basel) 2020; 12:cancers12103032. [PMID: 33081050 PMCID: PMC7603084 DOI: 10.3390/cancers12103032] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2020] [Revised: 10/15/2020] [Accepted: 10/16/2020] [Indexed: 11/17/2022] Open
Abstract
Simple Summary The necessity of completion total thyroidectomy is unclear in patients with papillary thyroid microcarcinoma (PTMC) with only pathological central lymph node metastasis (pCLNM). The aim of our study was to determine the necessity of completion total thyroidectomy after an initial surgery by comparing the prognosis according to the presence of pCLNM during a long-term follow-up. We retrospectively compared the pathological central lymph node (pCLN)-positive group of 165 patients who underwent thyroid lobectomy with the pCLN-negative group of 711 patients and found no difference between the two groups in the recurrence rate and disease-free survival rates. Therefore, PTMC patients who underwent thyroid lobectomy with prophylactic central compartment neck dissection and were diagnosed with pCLNM after surgery do not require completion total thyroidectomy. Abstract The necessity of completion total thyroidectomy in patients with papillary thyroid microcarcinoma (PTMC) and pathological central lymph node metastasis (pCLNM) who underwent thyroid lobectomy with central compartment neck dissection (CCND) is unclear. We determined the necessity of completion total thyroidectomy by retrospectively comparing the prognosis according to the presence of pCLNM during a long-term follow-up. We enrolled 876 patients with PTMC who underwent thyroid lobectomy with prophylactic CCND from January 1986 to December 2009. Patients were divided according to central lymph node (CLN) metastasis: 165 (18.8%) and 711 (81.2%) in the CLN-positive and CLN-negative groups, respectively. Medical records were reviewed retrospectively, and clinicopathologic characteristics and recurrence rates were analyzed. The CLN-positive group was associated with male sex (p = 0.001), larger tumor size (p < 0.001), and more microscopic capsular invasion (p < 0.001) compared with the CLN-negative group. There was no significant difference between the two groups’ recurrence (p = 0.133) or disease-free (p = 0.065) survival rates. Univariate and multivariate analyses showed no factors associated with tumor recurrence except male sex (hazard ratio = 3.043, confidence interval 1.117–8.288, p = 0.030). Patients who were diagnosed with pCLNM after undergoing thyroid lobectomy with prophylactic CCND do not require completion total thyroidectomy; however, frequent follow-up is necessary for patients with PTMC and pCLNM.

Eur Radiol 2020; 31:2877-2885. [PMID: 33057762 DOI: 10.1007/s00330-020-07384-6] [Citation(s) in RCA: 34] [Impact Index Per Article: 8.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2020] [Revised: 08/27/2020] [Accepted: 10/06/2020] [Indexed: 01/25/2023]
Abstract
OBJECTIVES To summarize and compare unnecessary biopsy rates and diagnostic performance in the examination of thyroid nodules according to four representative US-based risk stratification systems. METHODS MEDLINE/PubMed and EMBASE databases were searched to identify original articles investigating unnecessary biopsy rates according to at least one of the following guidelines: ACR-TIRADS, ATA, EU-TIRADS, and K-TIRADS. The unnecessary biopsy rates for each risk stratification system were pooled using a random-effects model. Meta-regression analyses were performed to explore heterogeneity. Diagnostic odds ratios (DORs) for the appropriate selection of thyroid nodules for fine-needle aspiration were also pooled using a bivariate random-effects model. RESULTS Eight articles including 13,092 thyroid nodules met the eligibility criteria and were included. The pooled unnecessary biopsy rates of ACR-TIRADS, ATA, EU-TIRADS, and K-TIRADS were 25% (95% CI, 22-29%), 51% (95% CI, 44-58%), 38% (95% CI, 16-66%), and 55% (95% CI, 42-67%), respectively. The pooled unnecessary biopsy rate of ACR-TIRADS was significantly lower than that of ATA (p < .001) and K-TIRADS (p < .001), and also lower than that of EU-TIRADS, but not reaching statistical significance (p = .087). The pooled DORs of ACR-TIRADS, ATA, and K-TIRADS were 5.9 (95% CI, 3.6-9.6), 6.3 (95% CI, 4.5-8.8), and 4.5 (95% CI, 1.7-11.6), respectively, with the differences not being statistically significant. CONCLUSIONS ACR-TIRADS showed a lower unnecessary biopsy rate than the other risk stratification systems albeit DOR was comparable between ACR-TIRADS, ATA, and K-TIRADS. Future revisions of each system should be made by referring to ACR-TIRADS to reduce unnecessary biopsy rates. KEY POINTS • The pooled unnecessary biopsy rates of ACR-TIRADS, ATA, EU-TIRADS, and K-TIRADS were 25% (95% CI, 22-29%), 51% (95% CI, 44-58%), 38% (95% CI, 16-66%), and 55% (95% CI, 42-67%), respectively. • The pooled unnecessary biopsy rate of ACR-TIRADS was significantly lower than that of ATA (p < .001) and K-TIRADS (p < .001). • The pooled DORs of ACR-TIRADS, ATA, and K-TIRADS were 5.9 (95% CI, 3.6-9.6), 6.3 (95% CI, 4.5-8.8), and 4.5 (95% CI, 1.7-11.6), respectively, with the differences not being statistically significant.

Abstract
The incidence of thyroid cancer has been increasing exponentially worldwide, mainly due to increased detection of small papillary thyroid microcarcinomas (PTMCs). Given the indolent nature of the disease, active surveillance (AS) has been suggested as an alternative approach to immediate surgery in the management of low-risk PTMCs. The decision to proceed with AS must take into account patient characteristics, tumor characteristics, and medical team characteristics. In this review, we discuss the rationale and evidence to support AS, as well as important considerations and limitations to implementing this approach for PTMC worldwide.

Abstract
PURPOSE OF REVIEW Thyroid cancer is the most common endocrine cancer in adults with rising incidence. Challenges in imaging thyroid cancer are twofold: distinguishing thyroid cancer from benign thyroid nodules, which occur in 50% of the population over 50 years; and correct staging of thyroid cancer to facilitate appropriate radical surgery in a single session. The clinical management of thyroid cancer patients has been covered in detail by the 2015 guidelines of the American Thyroid Association (ATA). The purpose of this review is to state the principles underlying optimal multimodal imaging of thyroid cancer and aid clinicians in avoiding important pitfalls. RECENT FINDINGS Recent additions to the literature include assessment of ultrasound-based scoring systems to improve selection of nodules for fine needle biopsy (FNB) and the evaluation of new radioactive tracers for imaging thyroid cancer. SUMMARY The mainstay of diagnosing thyroid cancer is thyroid ultrasound with ultrasound-guided FNB. Contrast-enhanced computed tomography and PET with [F]-fluorodeoxyglucose (FDG) and MRI are reserved for advanced and/or recurrent cases of differentiated thyroid cancer and anaplastic thyroid cancer, while [F]FDOPA and [Ga]DOTATOC are the preferred tracers for medullary thyroid cancer.

Abstract
In 1993, active surveillance of low-risk papillary thyroid microcarcinomas (PTMCs) started in Kuma Hospital, Kobe, Japan. It has spread globally after the publishing of American Thyroid Association (ATA) guidelines. During our hospital's active surveillance program, few patients (8.0%) showed tumor size enlargement ≥3 mm or the new appearance of node metastasis (3.8%) at 10-year follow-up. Conversion surgery was recommended for patients with disease progression. To date, no patients showed significant recurrence or metastasis or died with thyroid carcinoma when patients underwent active surveillance or after surgery due to PTMC progression. Unlike clinical papillary thyroid carcinoma (PTC), elderly patients' PTMCs were less progressive compared to those of young and middle-aged patients, indicating that elderly patients are strong candidates for the active surveillance of their PTMC. Although young patients' PTMCs are the most progressive, >50% and >75% of patients in their 20s and 30s would avoid conversion surgical treatment in their lifetime, respectively (according to estimated lifetime probability), indicating that such young patients are still candidates for active surveillance. It can thus be concluded that active surveillance is appropriate to be first management for PTMCs, based on the accumulation of favorable outcomes of PTMC patients who have undergone active surveillance, as well as the lower incidences of unfavorable events and lower medical cost than immediate surgery.

Abstract
PURPOSE To describe the outcomes and the incidence of adverse events following active surveillance (AS) versus immediate surgery in patients with low-risk papillary thyroid carcinoma (PTC). METHODS We prospectively evaluated 286 patients who attended the Hospital de Clínicas, with a single thyroid nodule <1.5 cm classified as Bethesda category V or VI (PTC). Those patients with no aggressive features were considered as harboring a low-risk PTC and were offered AS or immediate surgery. For patients who opted for AS, surgery was recommended if tumor progression was observed. Post-operative adverse events were recorded for those patients treated with surgery (after AS or immediate surgery). RESULTS From 286 eligible patients, 164 harbored a low-risk PTC. Among these, 75% (n = 123) underwent immediate surgery and 25% (n = 41) opted for AS. Within the last group, increase in tumor size more than 3 mm was observed in 14.6 and 4.8% was diagnosed with lymph-node metastases after a median of 37.5 months (range, 12-65) of follow-up. One hundred and thirty five patients underwent surgery: in 123, it was immediate after diagnosis and in 12 after a median of 35 months (range, 12-65) of AS. Both groups had excellent oncological outcomes. The frequency of postoperative adverse events was 24.4%, which was permanent in 9.6% of cases. The immediate-surgery group presented higher incidence of permanent vocal cord paralysis (2.4 vs. 0%); permanent hypoparathyroidism (5.7 vs. 0%) and local complications (4 vs. 2.4%) compared with the AS group, all non-statistically significant. CONCLUSIONS The high incidence of postoperative complications observed in our media could be avoided if AS was performed as the initial approach in patients with low-risk PTCs. The frequency of tumor growth and LN metastases during AS was similar to other series.

Abstract
BACKGROUND The prognosis of patients with papillary thyroid cancer (PTC) who have undergone surgery is usually good. But surgery is risky for elderly patients. The outcomes of surgery or nonsurgery for the very elderly PTC patients have not been reported. Here, we investigated the effect of surgery or not on prognosis in very elderly PTC patients (aged ≥85 y). METHODS A retrospective study was performed based on data from the Surveillance, Epidemiology, and End Results program. The outcomes of surgery and nonsurgery in very elderly PTC patients were compared using different statistical methods, including propensity score matching. RESULTS A total of 1196 very elderly patients with PTC were enrolled in the study. Patients who underwent surgery (n = 871) had a much better prognosis than those who did not (n = 325) in both overall survival and cancer-specific survival (P < 0.001). In the multivariate analysis, nonsurgery was an independent predictor for both overall survival (hazard ratio = 2.066; P < 0.001) and cancer-specific survival (hazard ratio = 2.768; P < 0.001). CONCLUSIONS Surgery is positively associated with an improved prognosis of PTC patients aged ≥85 y and is still suggested for these patients after appropriate risk assessment.

Abstract
The Japan Associations of Endocrine Surgeons has developed the revised version of the Clinical Practice Guidelines for Thyroid Tumors. This article describes the guidelines translated into English for the 35 clinical questions relevant to the therapeutic management of thyroid cancers. The objective of the guidelines is to improve health-related outcomes in patients with thyroid tumors by enabling users to make their practice evidence-based and by minimizing any variations in clinical practice due to gaps in evidential knowledge among physicians. The guidelines give representative flow-charts on the management of papillary, follicular, medullary, and anaplastic thyroid carcinoma, along with recommendations for clinical questions by presenting evidence on the relevant outcomes including benefits, risks, and health conditions from patients' perspective. Therapeutic actions were recommended or not recommended either strongly (◎◎◎ or XXX) based on good evidence (😊)/good expert consensus (+++), or weakly (◎, ◎◎ or X, XX) based on poor evidence (😣)/poor expert consensus (+ or ++). Only 10 of the 51 recommendations given in the guidelines were supported by good evidence, whereas 35 were supported by good expert consensus. While implementing the current guidelines would be of help to achieve the objective, we need further clinical research to make our shared decision making to be more evidence-based.

Abstract
OBJECTIVE To evaluate the efficacy and safety of radiofrequency ablation (RFA) for low-risk papillary thyroid microcarcinoma (PTMC) in a large population. MATERIALS AND METHODS Cases of 152 biopsy-proven PTMCs from 133 patients who had undergone RFA for PTMC between May 2008 and January 2017 were included in this study. All patients were either of high surgical risk or refused to undergo surgery. They were followed up for at least 6 months after initial RFA. Ultrasonography (US) and computed tomography were performed to evaluate the PTMC and the presence of neck metastasis before treatment. RFA was conducted using an internally cooled thyroid-dedicated electrode system. Follow-up US was performed at 1 week, and 2, 6, and 12 months, after the initial RFA, and then at every 6-12 months. We evaluated serial changes of ablated tumors, newly developed cancers, lymph node (LN) or distant metastasis and complications. RESULTS Complete disappearance was found in 91.4% (139/152) of ablated tumors. Among the 13 tumors in patients who did not show complete disappearance, no tumor displayed any regrowth of the residual ablated lesion during the follow-up period. The mean follow-up period was 39 months. During the follow-up period, there were no local recurrence, no LN or distant metastasis, and no newly developed thyroid cancers. No patients were referred to surgery. The overall complication rate was 3% (4/133) of patients, including one voice change. There were no life-threatening complications or procedure-related deaths. CONCLUSION Our results suggest that RFA is an effective and safe option for treating low-risk PTMC patients who are of high surgical risk or refuse surgery.

Abstract
INTRODUCTION Thyroid cancer is the most common endocrine malignancy. Multiple different staging systems have been introduced and used for differentiated thyroid carcinoma (DTC). AREAS COVERED In this literature review we provide an overview of the standard options for management of patients with low risk differentiated thyroid cancer. EXPERT OPINION Surgery is considered the first and most important step in managing DTC with goal to remove all the malignant foci in order to achieve cure and increase the survival with least chance of recurrence. Many studies have been conducted to determine the best surgical approaches and how aggressive surgeries should be in order to achieve the best outcomes regarding efficacy as well as safety. Radioactive iodine (RAI) therapy has also been a part of the treatment regimen and is used for different purposes with three main goals: post-surgical ablation, adjuvant therapy and persisted/recurrent disease treatment. Radiation therapy, on the other hand, is still not recommended to be used routinely in DTC because of the conflicting data of its benefit.

Abstract
Background: Active surveillance (AS) of small, low-risk papillary thyroid cancers (PTCs) is increasingly being considered. There is limited understanding of why individuals with low-risk PTC may choose AS over traditional surgical management. Methods: We present a mixed-methods analysis of a prospective observational real-life decision-making study regarding the choice of thyroidectomy or AS for management of localized, low-risk PTCs <2 cm in maximum diameter (NCT03271892). Patients were provided standardized medical information and were interviewed after making their decision (which dictated disease management). We evaluated patients' levels of decision-self efficacy (confidence in medical decision-making ability) at the time information was presented and their level of decision satisfaction after finalizing their decision (using standardized questionnaires). We asked patients to explain the reason for their choice and qualitatively analyzed the results. Results: We enrolled 74 women and 26 men of mean age 52.4 years, with a mean PTC size of 11.0 mm (interquartile range 9.0, 14.0 mm). Seventy-one patients (71.0% [95% confidence interval 60.9-79.4%]) chose AS over surgery. Ninety-four percent (94/100) of participants independently made their own disease management choice; the rest shared the decision with their physician. Participants had a high baseline level of decision self-efficacy (mean 94.3, standard deviation 9.6 on a 100-point scale). Almost all (98%, 98/100) participants reported high decision satisfaction. Factors reported by patients as influencing their decision included the following: perceived risk of thyroidectomy or the cancer, family considerations, treatment timing in the context of life circumstances, and trust in health care providers. Conclusions: In this Canadian study, ∼7 out of 10 patients with small, low-risk PTC, who were offered the choice of AS or surgery, chose AS. Personal perceptions about cancer or thyroidectomy, contextual factors, family considerations, and trust in health care providers strongly influenced patients' disease management choices.

Abstract
In recent decades, while the incidence of thyroid cancer has increased exponentially around the world, mortality has remained stable. The vast majority of this increase is attributable to the identification of intrathyroidal papillary microcarcinomas, which exhibit slow growth rates with indolent courses. A diagnosis of thyroid cancer based upon the presence of these small tumors could be considered as an overdiagnosis, as the majority of these tumors would not likely result in death if left untreated. Although surgical resection was the classical standard therapy for papillary microcarcinomas, active surveillance (AS) has emerged over the last three decades as an alternative approach that is aimed to recognize a minority group of patients who will clinically progress and would likely benefit from rescue surgery. Despite the encouraging results of AS, its implementation in clinical practice is strongly influenced by psychosocial factors. The aim of this review is to describe the epidemiology, clinical evolution, prognostic factors, and mortality of papillary thyroid microcarcinomas. We also summarize the AS strategy according to published evidence, characterize the criteria for selecting patients for AS according to risk factors and environmental characteristics, as well as analyze the current limitations for AS implementation.

Abstract
OBJECTIVE To assess relative clinical and economic performance of the revised American Thyroid Association (ATA) thyroid cancer guidelines compared to current standard of care. BACKGROUND Diagnosis of thyroid cancer in the United States has tripled whereas mortality has only marginally increased. Most patients present with small papillary carcinomas and have historically received at least a total thyroidectomy as a treatment. In 2015, the ATA released the revised guidelines recommending an option for active surveillance (AS) of small papillary thyroid carcinoma and thyroid lobectomy for larger unifocal tumors. METHODS We created a Markov microsimulation model to evaluate the performance of the ATA's 2015 guidelines compared to the ATA's 2009 guidelines. We modeled a cohort of simulated patients with demographic and thyroid nodule characteristics representative of those presenting clinically in the United States. Outcome measures include life expectancy, quality-adjusted life years, costs, and frequency of surgical adverse events. RESULTS In our base case analysis, the ATA 2015 strategy dominates the ATA 2009 strategy. The ATA 2015 strategy delivers greater discounted average quality-adjusted life years (13.09 vs 12.43) at a lower discounted average cost ($14,752 vs $20,126). Deaths due to thyroid cancer under the 2015 strategy are higher than the 2009 strategy but this is offset by a reduction in surgical deaths, leading to greater average life expectancy under the ATA 2015 strategy. The optimal strategy is sensitive to patients who experience a greater decrement in quality of life while undergoing AS. CONCLUSIONS The ATA 2015 Guidelines represent a cost-effective strategy regarding AS and extent of surgery.

Abstract
Background: While aspirin use is known to be associated with reduced incidence of various cancer types, it is unclear whether this benefit extends to thyroid cancer. We aimed to evaluate the association between aspirin use and thyroid cancer development. Methods: This nested case-control study used nationwide data from the Korean National Health Insurance Service-National Sample Cohort 2002-2015. In total, 4547 individuals with newly developed thyroid cancer were matched with 13,641 controls based on age, sex, and follow-up period. Odds ratios (ORs) and 95% confidence intervals (CIs) for thyroid cancer development according to aspirin use were analyzed using a multivariable conditional logistic regression model. Results: The number of days for which patients with thyroid cancer used aspirin (the proportions of no use, <30 days/year, 30-90 days/year, and ≥90 days/year were 93.03%, 6.51%, 0.31%, and 0.15%, respectively) was comparable with that of the controls (p = 0.371, chi-squared test). The risk of thyroid cancer development was not associated with the duration of aspirin use (ORs [CI] for aspirin use <30 days/year, 30-90 days/year, and ≥90 days/year were 1.11 [0.96-1.28], 1.01 [0.54-1.88], and 1.23 [0.50-3.06], respectively, compared with no use) after adjusting for body mass index, smoking status, hypertension, Charlson comorbidity index, and number of outpatient visits per year. In addition, subgroup analyses stratified by age, sex, and follow-up duration did not reveal any significant association between aspirin use and thyroid cancer. Conclusions: Our findings suggest that even extended aspirin use may not impact the prevention or onset of thyroid cancer.

Abstract
BACKGROUND In the Netherlands, differentiated thyroid cancer (DTC) is treated surgically in three different hospital types, including university, teaching, and non- teaching peripheral hospitals. This study evaluates postoperative complications and referral patterns in patients with DTC in the northern region of the Netherlands to gain an understanding on how to improve management implementation. METHODS Data from 567 patients diagnosed between 1989 and 2009 were obtained from the Netherlands Cancer Registry and were supplemented with information from hospital digital information systems and patient records from 15 hospitals: 1 university, 3 teaching, and 11 peripheral hospitals. Surgically treated patients with a histologically proven DTC derived from the original pathology reports were included. RESULTS Surgical treatment could be performed in a single procedure in 234 patients (41.3%), but several surgeries were needed in the remaining 333 patients (58.7%). Recurrent laryngeal nerve (RLN) palsy occurred after all types of thyroid surgical procedures, but mostly after initial (hemi)thyroidectomy and reoperations. RLN was temporary in 3.2% of the nerves at risk and persistent in 1.8%. Temporary hypocalcemia developed in 13.7% of patients, and persistent hypocalcemia occurred in 4.8%. Patients were mainly referred to the university hospital from a non-teaching (40.7%, 48/118) or teaching hospital (11.1%, 16/144); however, 80% of patients were not referred. CONCLUSIONS The complication rate and number of multiple surgeries support the efforts in optimizing clinical management in thyroid cancer. Careful considerations prior to initial surgical treatment by early discussion in telemedicine-based regional tumor boards could possibly prevent reoperations and potentially diminish complications.

Abstract
OBJECTIVES With a steadily increasing thyroid cancer incidence, information regarding cancer aggressiveness is essential to determine which patients may be suitable for active surveillance. This study assessed the extent of non-aggressiveness of untreated, local and regional stage, papillary thyroid cancer. MATERIALS AND METHODS We used the Surveillance, Epidemiology, and End Results (SEER) registry and included 1423 local stage and 337 regional stage papillary thyroid cancer cases. Thyroid cancer specific survival was estimated conditional on the absence of death due to competing causes using competing risk methods. Stratified analyses were done to determine non-aggressiveness among different patient and tumor characteristics. RESULTS The overall rate of non-aggressiveness for local stage thyroid cancer was 99.34% (95% CI: 99.33-99.35%), with a rate of non-aggressiveness of 98.85% (95% CI: 98.77-98.93%) for males and 99.48% (95% CI: 99.46-99.49%) for females (p = 0.055). Rate of non-aggressiveness was significantly lower in patients >60 years compared to patients ≤60 years (p < 0.001). Although the rate of non-aggressiveness was the same for tumors ≤10 mm and tumors of 11-20 mm, tumors measuring >20 mm had a significantly lower rate of non-aggressiveness (p = 0.002). The overall rate of non-aggressiveness for regional stage thyroid cancer was 72.58% (95% CI: 70.61-74.56%). CONCLUSION We found high rates of non-aggressiveness in untreated, local stage, papillary thyroid cancer, particularly in younger patients with small (≤2 cm) thyroid cancer, suggesting that these patients may be good candidates for active surveillance.

Abstract
The incidence of papillary thyroid microcarcinoma (microPTC) has dramatically increased in the last decades. Most of these tumors remain small and clinically "silent", only small number progress. Although thyroid surgery used to be the only therapeutic approach, recent guidelines now consider active surveillance for low-risk microPTC. For this reason, more accurate risk stratification of microPTC is needed. The optimal management of low-risk microPTC through accurate risk stratification represents a major clinical issue.

Abstract
CONTEXT The dramatic rise in the incidence of thyroid cancer over the last 30 years is largely attributable to the increasing diagnosis of papillary microcarcinomas (mPTCs). Current guidelines endorse an observational management approach in properly selected cases. OBJECTIVE To evaluate the feasibility of active surveillance in mPTC in Italy, its impact on real life, and to identify risk factors of progression. DESIGN AND SETTING In 2014 we started a prospective-observational study of active surveillance in mPTC patients. PATIENTS Included patients demonstrated a single Thy4 or Thy5 thyroid nodule, with largest diameter ≤1.3 cm, and no suspicious laterocervical lymph nodes by neck ultrasonography. Of 185 eligible subjects, 50.3% (93/185) enrolled in the observational management protocol while the others opted for surgery and were excluded from this analysis. INTERVENTION Enrolled patients were followed with neck ultrasound at 6- to 12-month intervals. Disease progression was defined as the appearance of abnormal lymph nodes or nodule enlargement during follow-up. In these cases, patients were directed to surgery. RESULTS Three patients (3/93, 3%) showed clinical progression and required surgery. Another 19 patients (19/93, 20%) decided to transition to surgical intervention even though there was no evidence of disease progression. All operated patients had excellent response to initial treatment despite the delayed surgery. CONCLUSIONS Within an Italian medical context, active surveillance appears to be a feasible and safe alternative to immediate surgery in healthy mPTC patients. Only 3% of mPTC demonstrated disease progression during a median follow-up of 19 months (range 6-54) and importantly demonstrated excellent outcomes after surgical intervention in a short-term follow-up.

Abstract
Importance The burden of concern for patients with thyroid cancer who undergo surgical intervention with or without radioactive iodine is known to be substantial. For patients under active surveillance, this aspect of the patient experience has not been described to date and could be a potential barrier to broader acceptance of surveillance as a cancer management strategy. Objective To describe the experiences of patients in the longest-standing and largest thyroid cancer active surveillance program. Design, Setting, and Participants This study used a mixed method of survey, semistructured interviews, and field observation and was conducted at Kuma Hospital in Kobe, Japan. The survey was administered from September 4, 2017, through October 18, 2017, and the field observation was conducted from August 28, 2017, to October 20, 2017. Survey participants were a consecutive sample of 249 patients under active surveillance who were attending the hospital for a surveillance visit, and the semistructured interviewees were a subset of 21 patients. The English-language survey instrument was translated by native Japanese speakers, back-translated into English, and then further refined by a panel of Japanese speakers with expertise in health research. Main Outcomes and Measures Survey and interview responses and field observations. Results In total, 249 surveys were distributed to patients with thyroid cancer on active surveillance. Two hundred forty-three patients (97.6%) completed the survey. Among the respondents, 195 (80.2%) were female and 20 (8.2%) were male (28 [11.5%] responses were missing). Among the subset of 21 patients who participated in the semistructured interview, 3 were male (14.3%), and the mean (range) age was 64 (32-85) years. Thirty-seven percent rated the frequency of cancer worry as occurring sometimes or more. Thirty-two percent said their worry affected their mood somewhat or a lot. Fourteen percent reported that their worry affected their ability to carry out daily activities somewhat or a lot. Cancer spread, later need for surgical intervention, and difficulty with interpreting bodily experiences in the general location of the cancer were among the main sources of worry. Most respondents (60.0%) said their worry was less than it was when they first found out about their cancer. By 3 years after diagnosis, the proportion of participants who reported they were not at all worried increased from 14% (95% CI, 12%-16%) to 25% (95% CI, 23%-26%). Eighty percent (95% CI, 79%-81%) of respondents agreed or strongly agreed that their decision to do active surveillance matched their personal values, and 83% (95% CI, 82%-84%) agreed or strongly agreed that choosing active surveillance was the best decision for them personally. Most patients (77%) had not heard of active surveillance before they were offered the option. Conclusions and Relevance Cancer concern was common among patients with thyroid cancer under active surveillance, which is comparable to the worry among actively treated patients. Levels of cancer worry reported by patients under active surveillance decreased over time, and patients expressed satisfaction with their disease management decision. These findings suggest that the possibility of cancer worry should not be viewed as prohibitive to successful active surveillance in thyroid cancer.

Abstract
Importance Concerns around possible overdiagnosis and overtreatment of differentiated thyroid cancer (DTC) have been raised. Issues concerning health-related quality of life (HRQOL) after diagnosis and treatment of DTC are understudied in this patient group. Objective To better understand the range of HRQOL outcomes, including possible adverse effects of treatment, associated with diagnosis and treatment of DTC and whether these outcomes vary by type of surgery received. Design, Setting, and Participants This content analysis assessed responses to an open-ended question about outcomes and concerns after DTC diagnosis and treatment among patients ascertained from the major postsurgical thyroid cancer treatment center and the population-based Cancer Registry in Queensland, Australia. Participants were aged 18 to 79 years and recently diagnosed with throid cancer. Responses underwent analysis to identify and code emergent themes to describe HRQOL issues and adverse effects of treatment experienced. Quantitative analysis was used to explore whether surgery type was associated with HRQOL issues and/or adverse effects of treatment. Of 1416 eligible patients, 1005 (71.0%) participated. Data were collected from July 1, 2013, through August 31, 2016, and analyzed from January 11 through April 9, 2018. Main Outcomes and Measures Issues concerning HRQOL. Results The analysis included 1005 patients (72.2% female [n = 726]; mean [SD] age, 52 [14.0 years) with DTC. Most patients were diagnosed with papillary thyroid cancer (889 of 1003 [88.6%]), had tumors smaller than 2 cm in size (564 of 1000 [56.4%]), and received a total thyroidectomy (791 of 1005 [78.7%]). Overall, 775 patients (77.1%) reported HRQOL issues after diagnosis and treatment of DTC. The following 4 main themes emerged from content analysis of patient responses: physical (663 [66.0%]), psychological (187 [18.6%]), lifestyle (82 [8.2%]), and no issue or adverse effect (246 [24.5%]). Patients who had a total thyroidectomy (without neck dissection) were 1.5 times (odds ratio, 1.49; 95% CI, 1.04-2.12) more likely to report an HRQOL issue or an adverse effect of treatment compared with patients who underwent a hemithyroidectomy. Conclusions and Relevance According to results of this study, patients diagnosed with DTC report wide-ranging HRQOL issues; these are more prevalent among patients who have total thyroidectomies rather than hemithyroidectomies. For patients with small, localized DTCs, hemithyroidectomy may offer fewer adverse effects of treatment and better HRQOL outcomes than total thyroidectomy. It appears that issues with HRQOL should be considered by patients and physicians when deciding on the best treatment approach after a diagnosis of DTC.

Abstract
Importance The cancer disease label may lead to overtreatment of low-risk malignant neoplasms owing to a patient's emotional response or misunderstanding of prognosis. Decision making should be driven by risks and benefits of treatment and prognosis rather than disease label. Objective To determine whether disease label plays a role in patient decision making in the setting of low-risk malignant neoplasms and to determine how the magnitude of the disease-label effect compares with preferences for treatment and prognosis. Design, Setting, and Participants A discrete choice experiment conducted using an online survey of 1314 US residents in which participants indicated their preferences between a series of 2 hypothetical vignettes describing the incidental discovery of a small thyroid lesion. Vignettes varied on 3 attributes: disease label (cancer, tumor, or nodule); treatment (active surveillance or hemithyroidectomy); and risk of progression or recurrence (0%, 1%, 2%, or 5%). The independent associations of each attribute with likelihood of vignette selection was estimated with a Bayesian mixed logit model. Main Outcomes and Measures The preference weight of the cancer disease label was compared with preference weights for other attributes. Results In 1068 predominantly healthy respondents (605 women and 463 men) with a median age of 35 years (range, 18-78 years), the cancer disease label played a considerable role in respondent decision making independent of treatment offered and risk of progression or recurrence. Participants accepted a 4-percentage-point increase in risk of progression or recurrence (from 1% to 5%) to avoid labeling their disease as cancer in favor of nodule (marginal rate of substitution [MRS], 1.0; 95% credible interval [CrI], 0.9-1.1). Preference for the nodule label instead of cancer was similar in magnitude to the preference for active surveillance over surgery (MRS, 1.0; 95% CrI, 0.9-1.1). Conclusions and Relevance Disease label plays a role in patient preference independent of treatment risks or prognosis. Raising the threshold for biopsy or removing the word cancer from the disease label may mitigate patient preference for aggressive treatment of low-risk lesions. Health care professionals should emphasize treatment risks and benefits and natural disease history when supporting treatment decisions for potentially innocuous epithelial malignant neoplasms.

Abstract
Importance Across many countries, a rapid escalation of the incidence of thyroid cancer has been observed, a surge that nonetheless underestimates the true extent of the disease. Most thyroid cancers now diagnosed comprise small, low-risk cancers that are incidentally found and are unlikely to cause harm. In many ways, prostate cancer similarly harbors a well-behaved subclinical reservoir, a long natural history, and superlative outcomes that have made active surveillance the de facto guideline recommendation for low-risk disease. This review highlights the parallels and differences between prostate cancer and thyroid cancer regarding screening, diagnosis, risk stratification, and considerations for active surveillance. Observations Prostate cancer and thyroid cancer have undergone recalibrated, de-escalatory shifts to counter changing epidemiologic landscapes. The US Preventive Services Task Force has issued cautionary recommendations on screening via prostate-specific antigen testing or neck ultrasonography, while the thresholds to performing biopsy have increased. Comparable changes to cancer terminology and staging have also helped alleviate patient anxiety and minimize pressure for overtreatment. Long-term, randomized prospective clinical trials for prostate cancer have established active surveillance as a first-line treatment approach for properly stratified low-risk patients, while observational trials for thyroid cancer have also made strides in defining risk and eligibility for surgery. Caveats requiring deeper investigation include aggressive disease in older patients, underestimation of the extent of the disease, and patient-physician bias in shared decision making. For prostate cancer, survival may not improve and function will likely worsen after intervention; for thyroid cancer, patients are younger, surgery is safer, and the bar for surveillance will likely be higher. Conclusions and Relevance Despite similarities in biological indolence between low-risk prostate and thyroid malignant neoplasms, key distinctions in life expectancy and treatment sequelae may ultimately confer somewhat disparate management paradigms for the 2 diseases. Nevertheless, the experience forged by prostate cancer trials serves as a model for thyroid cancer management, potentially reshaping the perception of active surveillance into a credible, valuable treatment modality.

Abstract
OBJECTIVE To provide an overview of the use and possible overuse of diagnostic neck ultrasound (DNUS) by describing and comparing both the ordering rates and the downstream results of DNUS by regions across Ontario. DESIGN Retrospective population-based cohort study based on electronic health care data. SETTING Ontario. PARTICIPANTS Ontario residents (adults aged > 18 years) who had a diagnosis of thyroid cancer between October 1, 1999, and June 30, 2014, and residents who had a DNUS in 2012. MAIN OUTCOME MEASURES Proportion of Ontario residents in each sub-Local Health Integration Network (LHIN) group who had their first DNUS in 2012 and went on to other relevant tests, diagnoses, and surgery. The sub-LHIN groups were based on increasing age- and sex-adjusted rates of first DNUS. RESULTS There were 77 238 DNUS tests in 2012 and there was a 7.4-fold variation in the rate of test ordering across the sub-LHIN populations leading to variable rates of actual disease, suggesting screening or uncertain indications for tests. CONCLUSION Across Ontario, the indications for ordering DNUS are variable, and screening or testing without indication might be a common practice. Establishing effective guidelines for the ordering of DNUS would potentially reduce costs and ultimately reduce the rates of thyroid cancer.

Abstract
Background and Aim: Limited information available about different types of thyroid surgeries with risk for postoperative hypothyroidism. This study aimed to investigate the risk of developing early and late-onset postoperative hypothyroidism in patients with thyroid disorders. Methods: We used a large cohort data from the Taiwan National Health Insurance Research Data Base (NHIRDB) and identified 9,693 (9, 348) patients from January 1998 to December 2010, admitted for thyroid disorder surgeries. We used the surgical procedures time as the index date. Our observational retrospective cohort study excluded the subjects diagnosed with hypoparathyroidism and hypothyroidism before any surgeries. We analyzed the data using the Cox regression model to calculate the hazard ratio. Result: Postoperative hypothyroidism associated with bilateral-total (HR, 4.27; 95% CI, 3.32-5.50), one-side total and another subtotal (HR, 3.16; 95% CI, 2.59-3.86), bilateral-subtotal (HR, 1.65; 95% CI, 1.37-1.98), and unilateral-total (HR, 1.17; 95% CI, 0.95-1.44) surgical procedures. The time intervals for thyroid disorders were 320 cases developed postoperative hypoparathyroidism in eight weeks, 480 cases the second month, and 1000 cases in the first year after surgery. Conclusion: Findings suggest that thyroidectomy was associated with transient postoperative hypothyroidism in thyroid disorder patients. The bilateral-total surgical procedure was strongly associated with temporary postoperative hypothyroidism.

Abstract
Active surveillance (AS) can be considered as a treatment strategy for low risk papillary thyroid microcarcinoma (PTMC), with the absence of clinically apparent lymph nodes, extrathyroidal extensions, and distant metastasis. After reviewing the reports on AS of low risk PTMCs worldwide, we introduced AS, and discussed the selection criteria for active surveillance candidates based on different guidelines and the follow-up schedules. Moreover, the requirement of cytological diagnosis, progression evaluation methods, necessity of thyrotropin suppression, and medical costs were issues that both clinicians and patients considered. The usefulness of AS for low risk PTMC patients depended on accurate and confidential evaluation of patient risk. Clinicians may adopt measures like dynamic monitoring, risk stratification, and making personal follow-up schedules to minimize these potential risks. By appropriately selecting PTMC patients, AS can be an effective alternative treatment to immediate surgery.

Abstract
Introduction: Active surveillance of low-risk papillary thyroid microcarcinomas (PTMCs) was initiated in Japan in 1993 and has since been adopted in many countries, especially after its approval by the American Thyroid Association in 2015.Areas covered: We performed a literature review in Medline/PubMed to identify studies that used active surveillance for PTMCs. Moreover, we performed a literature review about the increased incidence of thyroid microcarcinomas in relation to the relative stability of deaths due to thyroid carcinomas.Expert opinion: No patients showed life-threatening metastasis/recurrence or died of thyroid carcinoma during active surveillance or after conversion surgery following PTMC progression. Thus, active surveillance should be the first-line management of PTMCs without high-risk features. In the future, molecular testing of actively growing PTMCs using cytology specimens could be useful to guide the treatment plan.

Abstract
BACKGROUND About 3-9.2% of papillary thyroid carcinomas (PTC) are found in the isthmus, which has unique anatomic properties, making treatment more challenging. The aim of this study was to evaluate the treatment and undesirable effects of ultrasound-guided radiofrequency ablation (RFA) for PTC in the isthmus. METHODS This retrospective case series study assessed 112 patients with single papillary thyroid microcarcinoma in the isthmus, pathologically diagnosed before RFA at the General Hospital of Chinese PLA in 2014-2018. Follow-up was performed by contrast-enhanced ultrasound (CEUS) and ultrasound examinations at 1, 3, and 6 months and every 6 months thereafter. The complete ablation (CAR), disappearance (DR), and volume reduction (VRR) rates of nodules, the incidence of complications, and the rate of lymph-node metastasis were recorded. RESULTS The CAR of the tumors was 100%. During follow-up, the volume of coagulation necrosis gradually decreased. DRs at 1, 3, 6, 12, and 18 months after RFA were 0.8% (1/112), 10.7% (12/112), 51.7% (58/112), 91.0% (102/112), and 100% (112/112), respectively. The VRR evaluated by ultrasound and CEUS gradually increased. One recurrent case (0.8%) was found at 7 months after RFA. No complications, lymph node metastasis confirmed by ultrasound, and abnormal thyroid function were observed. CONCLUSIONS This retrospective study shows that RFA is beneficial for the treatment of PTMC in the isthmus.

Abstract
We are witnessing a rapid worldwide increase in the incidence of papillary thyroid carcinoma (PTC) in the last thirty years. Extensive implementation of cancer screening and wide availability of neck ultrasound or other imaging studies is the main reason responsible for this phenomenon. It resulted in a detection of a growing number of clinically asymptomatic PTCs, mainly low-risk tumors, without any beneficial impact on survival. An indolent nature of low-risk PTC, particularly papillary thyroid microcarcinoma (PTMC), and the excellent outcomes raise an ongoing discussion regarding the adequacy of treatment applied. The question of whether PTMC is overtreated or not is currently completed by another, whether PTMC requires any treatment. Current ATA guidelines propose less extensive preoperative diagnostics and, if differentiated thyroid cancer is diagnosed, less aggressive surgical approach and limit indications for postoperative radioiodine therapy. However, in intrathyroidal PTMCs in the absence of lymph node or distant metastases, active surveillance may constitute alternative management with a low progression rate of 1%-5% and without any increase in the risk of poorer outcomes related to delayed surgery in patients, in whom it was necessary. This review summarizes the current knowledge and future perspectives of active surveillance in low-risk PTC.

Abstract
OBJECTIVE Regional variation in thyroid cancer incidence in Belgium, most pronounced for low risk cancer, was previously shown to be related to variation in clinical practice, with higher thyroid surgery rates and lower proportions of preoperative fine-needle aspiration (FNA) in regions with high thyroid cancer incidence (period 2004-2006). The objective of this study was to investigate regional thyroid cancer incidence variation in relation with variation in thyroid surgery threshold in a more recent Belgian thyroid cancer cohort. METHODS A population-based cohort of thyroid cancer patients that underwent a (near) total thyroidectomy in the period 2009-2011 (n = 2,329 patients) was identified and studied by linking data from the Belgian cancer registry and the Belgian health insurance companies, and case-by-case study of the pathology protocols. The execution of preoperative FNA and the thyroid resection specimen weight were compared between high and low thyroid cancer incidence regions. Thyroid weight in the pT1a-restricted group was studied as a proxy for surgical threshold for benign nodular goiter. Furthermore, time trend analyses were performed for the execution of FNA for the period 2004-2012. RESULTS Although a lower proportion of FNA in the high thyroid cancer incidence region persisted in the period 2009-2011 (41.2% [31.9-50.9] vs. 72.9% [64.9-79.7] in the low-incidence region (LIR), p < 0.001), a positive time trend was observed for the period 2004-2012. The median thyroid surgical specimen weight was lower in the high incidence region compared to the LIR (27.0 g [IQR 18.0-45.3] vs. 36.0 g [IQR 22.0-73.0], p < 0.0001), and this finding was corroborated in the pT1a-restricted group. CONCLUSION Interregional differences in use of FNA and surgical thyroid specimen weight are consistent with an inverse relation between thyroid cancer incidence and thyroid surgery threshold, carrying risk for overdiagnosis.

Abstract
Background: Although clinical studies indicate that thermal ablation is effective in treating low-risk papillary thyroid microcarcinomas (PTMCs), the effectiveness of this treatment in patients with low-risk PTMC has not yet been systematically evaluated. Methods: Ovid-MEDLINE and EMBASE databases were searched for studies published through May 1, 2019, which report the efficacy of thermal ablation in patients with low-risk PTMCs. Data were extracted and methodological quality was assessed independently by two radiologists according to PRISMA guidelines. Results: This systematic review identified 503 low-risk PTMCs in 470 patients treated by thermal ablation from 9 studies. During follow-up, no patient experienced local tumor recurrence or distant metastasis, whereas two patients (0.4%) experienced lymph node (LN) metastasis. One patient (0.2%) developed a new PTMC, which was successfully treated by additional ablation. Five patients (1.1%) underwent delayed surgery after ablation, including the two patients with LN metastasis and three additional patients with unknown etiology. Conclusions: Thermal ablation is an excellent local tumor control method in patients with low-risk PTMCs. Strict inclusion criteria and technical expertise are required to obtain favorable results.

Abstract
An ever-increasing population of patients with papillary thyroid cancer is engaging with health care systems around the world. Numerous questions about optimal management have arisen that challenge conventional paradigms. This is particularly the case for patients with low-risk disease, who comprise most new patients. At the same time, new therapies for patients with advanced disease are also being introduced, which may have the potential to prolong life. This review discusses selected controversial issues in adult papillary thyroid cancer management at both ends of the disease spectrum. These topics include: (i) the role of active surveillance for small papillary cancers; (ii) the extent of surgery in low-risk disease (lobectomy vs total thyroidectomy); (iii) the role of postoperative remnant ablation with radioiodine; (iv) optimal follow-up strategies in patients, especially those who have only undergone lobectomy; and (v) new therapies for advanced disease. Although our current management is hampered by the lack of large randomized controlled trials, we are fortunate that data from ongoing trials will be available within the next few years. This information should provide additional evidence that will decrease morbidity in low-risk patients and improve outcomes in those with distant metastatic disease.

Abstract
The recent sharp increase in thyroid cancer incidence is mainly due to increased detection of small papillary thyroid microcarcinoma (PTMC). Due to the indolent nature of the disease, active surveillance (AS) of low-risk PTMCs is suggested as an alternative to immediate surgery to reduce morbidity from surgery. For appropriately selected PTMC patients, AS can be a good management option and surgical intervention can be safely delayed until progression occurs. Many considerations must be taken into account at the time of initiation of AS, including radiological tumor characteristics and clinical characteristics of the patient. A specialized medical team should be assembled to monitor patients during AS with an appropriate follow-up protocol. The fact that some patients require surgery for disease progression after long-term follow-up is a major drawback of the current AS protocol. Evaluation of tumor kinetics by three-dimensional tumor volume measurement during the initial 2-3 years of AS may be helpful for discrimination of PTMCs that need early surgical intervention. In this review, we will discuss the clinical outcomes of surgical intervention and AS, considerations during AS, and unresolved questions about AS.

Abstract
Background: Two Japanese prospective trials of active surveillance (AS) for adult patients with low-risk papillary thyroid carcinoma (PTC) ≤1 cm (cT1aN0M0 PTMC) have verified the safety of AS in oncological control and its superiority over immediate surgery with respect to unfavorable outcomes. Thus, AS has been accepted as an alternative to immediate surgery for asymptomatic papillary thyroid microcarcinomas (PTMCs). However, the real-world clinical approach for PTMC is unknown. Thus, this study aimed to investigate the current state of management of asymptomatic PTMCs in Japan. Methods: We conducted a questionnaire survey on the actual treatment patterns for adult patients with low-risk PTMCs. The subjects were member institutions of the Japan Association of Endocrine Surgery (JAES) or Japanese Society of Thyroid Surgery (JSTS), including the departments of surgery and head and neck surgery (HNS). Results: Responses were obtained from 134 institutes, where 72.4% of Japanese thyroid cancer cases operated by surgeons were treated. For suspicious tumors on ultrasound, 18 responders (13.4%) conducted cytological examination routinely, while 69 (51.5%) and 40 (27.8%) conducted it only for tumors >5 and >10 mm, respectively. After the diagnosis, 42 responders (31.3%) recommend AS, 35 (26.1%) recommend immediate surgery as the management, and 52 (38.8%) allowed patients to decide the treatment course. The present responders tended to recommend surgery for PTMCs that were located adjacent to the dorsal surface of the thyroid, were multiple, or measured almost 10 mm in size. At these institutions, 1176 patients with PTMC underwent surgery in 2017, accounting for 18.1% of surgeries for PTC. During the succeeding three months, 310 of 576 (53.8%) PTMC patients underwent AS. The treatment strategies did not differ between the departments (Surgery or HNS). The institutions that have six or more surgeons, that were located in metropolitan areas, or that were certified by JAES or JSTS performed AS more actively. Conclusion: More than 50% of low-risk PTMCs are on AS in Japan. However, the indication and recommendation for AS vary significantly between institutions. To improve the implementation of this management modality, physicians and patients should be further educated, and the sociomedical environment should be improved.

Abstract
Background: The rapid increase in the incidence of small papillary thyroid carcinoma (PTC) appears to be caused by the detection of small thyroid cancers. Active surveillance (AS) was therefore suggested to overcome this problem. As the results were favorable with low rates of size enlargement and lymph metastasis, the 2015 American Thyroid Association Management Guidelines endorsed AS as an alternative to immediate surgery. As the clinical value of AS is a subject of ongoing active discussions and surveys, we considered a systematic review and meta-analysis to be timely and necessary. Methods: Ovid-MEDLINE and EMBASE databases were searched up to January 5, 2019, for studies reporting patients who were followed up with AS for PTC. Data extraction and methodological quality assessment were performed independently by two radiologists. The primary outcomes were to identify the annual pooled proportions of size enlargement of 3 mm or more and the detection of lymph node metastases at a 5-year follow-up period. These were calculated using an inverse-variance weighting model. An additional outcome was evaluation of the reasons for surgery during AS. Results: The pooled proportion of size enlargement occurring at 5 years was 5.3% [95% confidence interval (CI), 4.4-6.4%], and the pooled proportion of 5-year lymph node metastasis was 1.6% [CI, 1.1-2.4%]. In many subjects undergoing delayed operations, the reasons for operation were often other than those of size enlargement or lymph node metastasis. Conclusions: AS is effective for the management of small PTC, with a low proportion of size enlargement or lymph node metastasis occurring at 5 years. However, a substantial proportion of the causes of delayed surgery were other than size enlargement or lymph node metastasis, and these situations need to be optimally managed.

Abstract
Importance Given evidence of overdiagnosis and overtreatment of small papillary thyroid cancers (PTCs), strategies are needed to promote the consideration of less invasive treatment options for patients with low-risk PTC. Objective To determine the association of treatment preferences and anxiety levels for PTC with the terminology used to describe the condition. Design, Setting, and Participants This randomized crossover study involved a community sample of 550 Australian men and women 18 years or older without a history of thyroid cancer. Between March 16, 2016, and July 26, 2016, participants accessed an online study that presented 3 hypothetical but clinically realistic scenarios, each of which described PTC as papillary thyroid cancer, papillary lesion, or abnormal cells. Participants were exposed to all 3 scenarios with the different terminologies, and participants were randomized by the order (first, second, or third) in which they viewed the terminologies. Data analysis was conducted from September 1, 2016, to May 15, 2017. Main Outcomes and Measures Treatment choice (total thyroidectomy, hemithyroidectomy, or active surveillance), diagnosis anxiety, and treatment choice anxiety. Results Of the 550 participants who completed the online study and were included in the analysis, 279 (50.7%) were female and the mean (SD) age was 49.9 (15.2) years. A higher proportion of participants (108 [19.6%]) chose total thyroidectomy when papillary thyroid cancer was used to describe the condition compared with the percentage of participants who chose total thyroidectomy when papillary lesion (58 [10.5%]) or abnormal cells (60 [10.9%]) terminology was used. At first exposure, the papillary thyroid cancer terminology led 60 of 186 participants (32.3%) to choose surgery compared with 46 of 191 participants (24.1%) who chose surgery after being exposed to papillary lesion terminology first (risk ratio [RR], 0.73; 95% CI, 0.53-1.02) and 47 of 173 participants (27.2%) after being exposed to abnormal cells (RR, 0.82; 95% CI, 0.60-1.14) terminology first. After the first exposure, participants who viewed papillary thyroid cancer terminology reported significantly higher levels of anxiety (mean, 7.8 of 11 points) compared with those who viewed the papillary lesion (mean, 7.0 of 11 points; mean difference, -0.8; 95% CI, -1.3 to -0.3) or abnormal cells (mean, 7.3 of 11 points; mean difference, -0.5; 95% CI, -1.0 to 0.01). Overall, interest in active surveillance was high and higher levels of anxiety were reported by those who chose surgery, regardless of which terminology was viewed first (mean difference, 1.5; 95% CI, 1.0-1.9). Conclusions and Relevance Changing the terminology of small PTCs may be one strategy to reduce patients' anxiety levels and help them consider less invasive management options. To curtail overdiagnosis and overtreatment in PTC, other strategies may include providing balanced information about the risks and advantages of alternative treatments.

Abstract
PURPOSE Papillary thyroid carcinoma (PTC), the most common malignant tumor of the thyroid, has been criticized as overtreated by some researchers in recent years. Active surveillance (AS) was first proposed at Kuma Hospital in 1993, and popularized in other institutes ever since. We provide a brief review of low-risk PTC active monitoring studies to date, and discuss the advantages of AS and limitations of existing studies. RESULTS Most papillary thyroid microcarcinomas do not show significant growth or new lymph node metastasis in a 10-year AS period. Patients who undergo delayed surgery during AS generally have a good prognosis. Tumor progression correlates with age, calcification pattern, and Ki-67 positivity. Serum thyroid stimulating hormone concentration and pregnancy might also influence tumor progression in some studies. CONCLUSION Active surveillance for low-risk PTC has shown its safety and feasibility in certain populations. In the future, it is warranted to determine valuable tumor progression predictors and most suitable PTC patients for AS.

Abstract
OBJECTIVES To determine the percentage of patients with papillary thyroid carcinoma (PTC) who accepted active surveillance as an alternative to surgery in our clinical practice and to describe the clinical characteristics and outcomes of patients with Bethesda category V and VI thyroid nodules who chose active surveillance. SUBJECTS AND METHODS We included 136 PTC patients from the Hospital de Clínicas, University of Buenos Aires without (i) US extrathyroidal extension, (ii) tumors adjacent to the recurrent laryngeal nerve or trachea, and/or (iii) US regional lymph-node metastasis or clinical distant metastasis. PTC progression was defined as the presence of i) a tumor larger than ≥ 3 mm, ii) novel appearance of lymph-node metastasis, and iii) serum thyroglobulin doubling time in less than one year. For patients with these features, surgery was recommended. RESULTS Only 34 (25%) of 136 patients eligible for active surveillance accepted this approach, and around 10% of those who accepted abandoned it due to anxiety. The frequency of patients with tumor enlargement was 17% after a median of 4.6 years of follow-up without any evidence of nodal or distant metastases. Ten patients who underwent surgical treatment after a median time of 4 years of active surveillance (AS) had no evidence of disease after a median of 3.8 years of follow-up after surgery. CONCLUSION Although not easily accepted in our cohort of patients, AS would be safe and easily applicable in experienced centers.

Abstract
Adapting treatment and follow-up according to the risk of recurrence and/or death from thyroid cancer is a relatively recent concept of "personnalized" medicine, developed particularly to avoid overtreatment of low-risk thyroid cancer which represents the majority of thyroid cancers diagnosed in the world today. For low-risk thyroid cancer, this decrease in extent of treatment involves the extent of surgery-total thyroidectomy, lobectomy or no surgery with active surveillance-but also the indications, doses and methods of stimulation when or if administering radioactive iodine (RAI), the indication for suppressive thyroxin therapy and the extent and modalities for follow-up that should be adapted to the risk of recurrence. The aim is to optimize medical resources and quality of life, particularly for low-risk patients whose life expectancy is that of the general population.

Abstract
BACKGROUND Incidence rates of thyroid cancer (TC) increased in the last decades worldwide. This study aimed to describe TC incidence in the Friuli Venezia Giulia (FVG) region, to estimate the quota of overdiagnosis, and to investigate the impact of surgery on long-term survival after TC diagnosis. METHODS TC cases reported to the FVG population-based cancer registry during 2002-2013, aged <85 years, were included. Age standardized rates (ASR) on the European population were computed, while proportion of TC overdiagnosis was estimated in comparison with expected age-specific incidence rates from published time series. Adjusted hazard ratios of death, with 95% confidence intervals, were also estimated. RESULTS During 2002-2013, 1701 TC cases were reported to the FVG cancer registry, with papillary TC (78.2%) as the most frequent histologic type. ASR increased from 12.4 to 16.5 in women and from 4.3 to 6.2 in men (+33.1% and +44.2%, respectively). Overdiagnosis was estimated as 79% of TC cases in women and 64% in men. Almost all TC cases (97.1%) underwent surgery, including 84.6% of women and 78.9% of men who underwent total thyroidectomy. Up to 10 years after TC diagnosis, the type of surgery did not appear to influence survival. CONCLUSIONS This study documented an increase in TC incidence in FVG in the last decade, with overdiagnosis accounting for a large proportion of TC diagnoses and total thyroidectomy in more than 80% of cases. These findings suggest reconsidering thyroid screening practice and aggressive therapeutic strategies, as recommended by new TC guidelines.

Abstract
The incidence of papillary thyroid microcarcinoma (PTMC) has increased dramatically in recent years. Compared with central lymph node metastases, lateral neck lymph node (LNLN) metastases in patients with PTMC were less studied. The aim of the present study is to analyze the predicting factors associated with LNLN metastases in patients with PTMC.A total of 3514 patients underwent thyroid surgery at our hospital from January 2017 to December 2017, and 936 patients with PTMC were selected and assessed retrospectively. They were further divided into 2 groups based on whether LNLN metastases existed or not. The relationship between LNLN metastases and clinicopathologic features of PTMC was analyzed.LNLN metastases were confirmed in 126 patients. Univariate and multivariate analyses found 5 independent factors associated with LNLN metastases. They were tumor size (≥0.7 cm) [odds ratio (OR) = 1.960, 95% confidence interval (95% CI) 1.227-3.131; P = .005], multifocality (OR = 2.254, 95% CI 1.398-3.634; P = .001), tumor location (upper portion) (OR = 6.312, 95% CI 3.853-10.340; P < .001), thyroid cancer family history (OR = 7.727, 95% CI 2.227-26.818; P = .001), and central lymph node metastases (OR = 11.810, 95% CI 6.547-21.302; P < .001).The findings of our study indicated that LNLN metastases were not rare in patients with PTMC, and tumor size (≥0.7 cm), multifocality, tumor location (upper portion), thyroid cancer family history, and central lymph node metastases were independent factors for LNLN metastases. In order to perform individualized management, LNLN should be meticulously evaluated when these features are detected.

Abstract
AIM To evaluate the safety, efficacy, and long-term outcomes of ultrasound-guided radiofrequency ablation (RFA) for the treatment of primary papillary thyroid microcarcinoma (PTMC). MATERIALS AND METHODS A total of 37 patients with 38 PTMC nodules underwent RFA at a power of 20 W between September 2014 and December 2017. The clinical data of these patients were reviewed retrospectively and analysed. Imaging studies of the nodules were conducted, and the patients' thyroid function was assessed before RFA; 1, 3, 6, and 12 months after RFA; and every 6 months thereafter. The volumes and volume reduction rate (VRR) of the nodules were also calculated. RESULTS RFA with a low power of 20 W was used in the treatment of 37 patients with 38 PTMC nodules. All nodules achieved complete ablation, no complications occurred, and thyroid function was not affected. During follow-up, the volume of the nodules gradually decreased. Twelve months after ablation, the mean volumes of the nodules significantly decreased to 0.01±0.03 ml with a VRR of 99.34±3.49%. At a median follow-up of 6 (range: 1-18) months, 37 of the 38 nodules were completely absorbed, and no recurrence was observed in all 37 patients. CONCLUSIONS Low-power RFA showed good safety and promising efficacy outcomes for the treatment of PTMC. In addition to surgery and active surveillance, RFA may be an alternative treatment option for patients with PTMC.

World J Surg Oncol 2019; 17:91.

Abstract
BACKGROUND Papillary thyroid microcarcinoma (PTMC) generally is a cancer with excellent prognosis, but the term "cancer" sounds severe and harsh, which can elicit emotional and physical responses from patients. To eliminate the word "cancer," the term noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) was introduced. However, not all PTMCs can be classified as NIFTP. Sometimes, very aggressive PTMC cases might be observed. Some authors suggest that one of the risk factors for poor prognosis is lymph node metastasis. The aim of the study was to evaluate some clinicopathological features of PTMC as the risk factors for lymph node metastasis. MATERIAL AND METHODS We performed a retrospective chart review and selected 177 patients with PTMC. To analyze the cases with potentially aggressive behavior, we enrolled PTMC patients with lymph node metastases (pN1, central, and/or lateral) and evaluated some of their clinicopathological features. RESULTS The logistic regression analysis results demonstrated significantly higher rates of multifocal or bilateral tumor occurrence in the PTMC patients with pN1 than in the patients with pN0 (P < 0.0001 for both). In addition, the occurrence of thyroid tumors with sizes above 0.5 cm was a significant risk factor for lymph node metastasis (P < 0.0001). The results of the ROC analyses showed that the presence of multifocal or bilateral tumors and tumor sizes above 0.5 cm were significant predictors of lymph node metastasis (P < 0.0001 for all). CONCLUSIONS Multifocal and bilateral PTMC tumors with diameters above 0.5 cm should be treated aggressively as "true cancer" and might benefit from lymph node dissection. Unifocal PTMC tumors with diameters equal to or below 0.5 cm may be treated less aggressively.
