Abstract
Robot-assisted transaxillary thyroidectomy is widely performed in Asian countries, although it is still under discussion in the Western World. However, there have been few studies reporting on the learning curve of robot-assisted transaxillary thyroidectomy. We used the cumulative sum (CUSUM) analysis to assess the learning curve of gasless robot-assisted transaxillary thyroidectomy at a third-level institution in Europe. We included all consecutive patients operated by a single surgeon without previous experience of robotic surgery from February 2012 to January 2023. The primary endpoint of the study was the learning curve extracted from the median operative time using the CUSUM method for the quantitative assessment. Overall, 583 patients were enrolled. The median operative time for thyroid lobectomy and total thyroidectomy was 70 and 90 min, respectively. The CUSUM analysis showed that the learning curve for thyroid lobectomy and total thyroidectomy is 66 and 56 cases, respectively. Moreover, the presence of thyroiditis resulted associated with shorter operative time for total thyroidectomy (p = 0.044), whereas no factors resulted associated with surgical complications. The learning curve for performing robotic transaxillary thyroid lobectomy for a surgeon without previous robotic experience is 66 cases. After that, 56 cases must be performed to acquire proficiency in robotic transaxillary total thyroidectomy. Training programs may reduce the slope of the learning curve.

Lee E, Jeong SH, Nam CM, Jun JK, Park EC. Role of breast cancer screening in the overdiagnosis of thyroid cancer: results from a cross-sectional nationwide survey. BMC Womens Health 2023; 23:64. [PMID: 36782225 PMCID: PMC9926730 DOI: 10.1186/s12905-023-02205-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2022] [Accepted: 02/01/2023] [Indexed: 02/15/2023] Open
Abstract
BACKGROUND South Korea has the highest incidence of thyroid cancer worldwide, raising questions regarding the possibility of overdiagnosis. Examining the factors affecting thyroid cancer screening is crucial in elucidating the reasons for this unusually high incidence of thyroid cancer. Therefore, in the present study, we investigated the association between breast cancer screening and thyroid cancer screening to determine the potential role of breast cancer screening in the overdiagnosis of thyroid cancer in South Korea. METHODS We analyzed the data of women aged > 30 years who were enrolled in the 2014 Korean National Cancer Screening Survey. Self-reported breast cancer screening behavior was categorized as follows: no screening, mammography only, ultrasonography only, and both ultrasonography and mammography. Thyroid cancer screening behavior was categorized as follows: those who had or had not undergone ultrasonography screening. Logistic regression analysis was used to examine the associations between breast and thyroid cancer screening behaviors. RESULTS Of the 2270 participants, a total of 569 (25.1%) were screened for thyroid cancer. Those who underwent only mammography, only ultrasonography, or both mammography and ultrasonography were more likely to be screened for thyroid cancer than those who did not undergo breast cancer screening (odds ratio [OR]: 1.47, 95% confidence interval [CI] 1.06-2.04; OR 2.71, 95% CI 1.83-4.02; OR 2.75, 95% CI 1.99-3.80, respectively). CONCLUSIONS Our findings indicate that thyroid cancer screening in Korea is likely to be performed on an opportunistic basis. Therefore, a nationwide public health and medical initiative is needed to curb the unnecessary use of thyroid screening in the asymptomatic general population.

Abstract
BACKGRUOUND In this study, we evaluated the recent changes in the standardized, age-specific, stage-specific incidence rates (IRs) of thyroid cancer in Korea and compared them with the incidence data reported by the Surveillance, Epidemiology, and End Results Program. METHODS The analysis was conducted using the incidence data (2005 to 2018) from the Statistics Korea and Korea Central Cancer Registry. RESULTS The age-standardized IR (SIR) of thyroid cancer increased from 24.09 per 100,000 in 2005 to 74.83 in 2012 (annual percent change [APC], 14.5). From 2012 to 2015, the SIR decreased to 42.52 (APC, -17.9) and then remained stable until 2018 (APC, 2.1). This trend was similar in both men and women. Regarding age-specific IRs, the IRs for ages of 30 years and older showed a trend similar to that of the SIR; however, for ages below 30 years, no significant reduction was observed from the vertex of IR in 2015. Regarding stage-specific IRs, the increase was more prominent in those with regional disease (APC, 17.4) than in those with localized disease until 2012; then, the IR decreased until 2015 (APC, -16.1). The average APC from 2005 to 2018 increased in men, those under the age of 30 years, and those with regional disease. CONCLUSION The SIR in Korea peaked in 2012 and decreased until 2015 and then remained stable until 2018. However, in young individuals under the age of 30 years, the IR did not significantly decrease but tended to increase again. In terms of stage-specific IRs, the sharpest increase was seen among those with regional disease.

Abstract
RATIONALE The public should be informed about overtesting and overdiagnosis. Diverse qualitative studies have examined public understandings of this information. A synthesis was needed to systematise the body of evidence and yield new, generalisable insights. AIM Synthesise data from qualitative studies exploring patient and public understanding of overtesting and overdiagnosis. METHODS We searched Scopus, CINAHL, Ovid MEDLINE and PsycINFO databases from inception to March 18, 2020. We included published English-language primary studies exploring the perspectives of patients/the public about overtesting/overdiagnosis from any setting, year and relating to any condition. Only qualitative parts of mixed-methods studies were synthesised. We excluded studies that only examined overtreatment or sampled people with specialised medical knowledge. Two authors independently selected studies, extracted data, assessed the methodological quality of included studies using the CASP tool, and assessed confidence in the synthesis findings using the GRADE-CERQual approach. Data was analysed using thematic meta-synthesis, utilising descriptive and interpretive methods. RESULTS We synthesised data from 21 studies, comprising 1638 participants, from 2754 unique records identified. We identified six descriptive themes, all graded as moderate confidence (indicating they are likely to reasonably represent the available evidence): i) high confidence in screening and testing; ii) difficulty in understanding overuse; iii) acceptance that overuse can be harmful; iv) rejection or problematisation of overuse; v) limited impacts of overuse information on intended test and screening uptake; vi) desire for information and shared decision-making regarding overuse. The descriptive themes were underpinned by two analytic themes: i) perceived intrinsic value of information and information gathering, and; ii) differences in comprehension and acceptance of overuse concepts. CONCLUSIONS This study identified novel and important insights about how lay people interpret overuse concepts. It will guide the development of more effective public messages about overuse, highlighting the importance of interpretative frameworks in these communications.

Abstract
OBJECTIVES The use of more medicalised labels can increase both concern about illness and the desire for more invasive treatment. This study analyses the media's coverage of an Analysis article in The BMJ which generated a large amount of high-profile international media coverage. It aims to understand how to better communicate messages about low-risk cancers and overdiagnosis to the public. DESIGN Content analysis of media coverage. SETTING Media was identified by Isentia Media Portal, searched in Google News and cross-checked in Factiva and Proquest databases from August 2018. METHODS Media headlines, full text and open access public comments responding to the coverage on the article proposing to 'rename low-risk conditions currently labelled as cancer' were analysed to determine the main themes. RESULTS 45 original media articles and their associated public comments (n=167) were identified and included in the analysis. Overall, headlines focused on cancer generally and there was little mention of 'low-risk', 'overdiagnosis' or 'overtreatment'. The full text generally presented a more balanced view of the evidence and were supportive of the proposal, however, public responses tended to be more negative towards the idea of renaming low-risk cancers and indicated confusion. Comments seemed to focus on the headlines rather than the full article. CONCLUSIONS This study offers a novel insight into media coverage of the complex and counterintuitive problem of overdiagnosis. Continued deliberation on how to communicate similar topics to the public through the mainstream media is needed. Future work in the area of low-risk cancer communication should consider the powerful impact of people's previous experience with a cancer diagnosis and the criticism about being paternalistic and concealing the truth from patients.

Abstract
Background: The incidence of thyroid cancer is increasing worldwide due to an increased detection of small well-differentiated papillary thyroid carcinomas. This study aimed to evaluate the effect of screening with ultrasonography on deaths from thyroid cancer. Materials and Methods: We conducted a matched case-control study using data from two sources representative of the adult Korean population. Cases were selected from the National Epidemiologic Survey of Thyroid Cancer database, and controls were selected from the Korean National Cancer Screening Survey database. Controls were individually matched to case patients with respect to age, sex, and area with a ratio of 10:1. The primary outcome was death from thyroid cancer. Controls were required to have been alive on the date of thyroid cancer diagnosis in the corresponding case. Results: The analysis included 120 patients who died from thyroid cancer and 1184 controls. Compared with those who had never been screened, the odds ratios for death from thyroid cancer among those who had been screened were 1.44 (95% confidence interval [CI] 0.68-3.05) if cases with missing information on screening were excluded and 1.13 [CI 0.49-2.63] if all cases were included, and missing information was imputed. Stratification by sex, year of diagnosis, and histological type did not show any statistically significant relationships between screening with ultrasonography and death from thyroid cancer, regardless of the statistical model used. Conclusions: Screening for thyroid cancer with ultrasonography does not prevent death from thyroid cancer; therefore, screening asymptomatic adults for thyroid cancer is unwarranted.

Abstract
OBJECTIVES To investigate public perceptions of overdiagnosis and overtreatment in low-risk thyroid cancer and explore opinions regarding the proposed strategy to change the terminology of low-risk cancers. DESIGN Qualitative study using focus groups that included a guided group discussion and presentation explaining thyroid cancer, overdiagnosis and overtreatment, and proposed communication strategies. Transcripts were analysed thematically. SETTING Sydney, Australia. PARTICIPANTS Forty-seven men and women of various ages from a range of socioeconomic backgrounds with no personal history of thyroid cancer. RESULTS Participants had low pre-existing general awareness of concepts of overdiagnosis and overtreatment and expressed concern regarding this new information in relation to thyroid cancer. Overall, participants understood why the strategy to change the terminology was being proposed and could see potential benefits including reducing the negative psychological impact and stigma associated with the term 'cancer'; however, many still had reservations about the strategy. The majority of the concerns were around their worry about the risk of further disease progression and that changing the terminology may create confusion and cause patients not to take the diagnosis and its associated managements seriously. Despite varied views towards the proposed strategy, there was a strong overarching desire for greater patient and public education around overdiagnosis and overtreatment in both thyroid cancer and cancer generally in order to complement any revised terminology and/or other mitigation strategies. CONCLUSIONS We found a strong and apparently widely held desire for more information surrounding the topic of overdiagnosis and overtreatment. Careful consideration of how to inform both the public and current patients about the implications of a change in terminology, including changes to patients' follow-up or treatments, would be needed if such a change were to go ahead.

Total thyroidectomy's association with survival in papillary thyroid cancers and the high proportion of total thyroidectomy in low-risk patients: Analysis of Korean nationwide data. Surgery 2018; 165:629-636. [PMID: 30342774 DOI: 10.1016/j.surg.2018.08.030] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2018] [Revised: 08/12/2018] [Accepted: 08/28/2018] [Indexed: 01/08/2023]
Abstract
BACKGROUND Papillary thyroid cancer has an excellent prognosis, but the appropriate level of treatment is controversial. We compared survival between total thyroidectomy and less-than-total thyroidectomy, and examined the proportion of patients with papillary thyroid cancer in Korea undergoing total thyroidectomy. METHODS A nationwide sample of 5,230 papillary thyroid cancer patients was included (total thyroidectomy: 4,262, less-than-total thyroidectomy: 968). Using multivariate Cox regression, we compared overall survival and cause-specific survival by the extent of thyroidectomy (total thyroidectomy versus less-than-total thyroidectomy) for a 1:1 optimal match via the propensity score and for the total study population. We also compared overall survival by extent of thyroidectomy and the proportion of total thyroidectomy in different risk groups using papillary thyroid cancer staging systems. RESULTS We saw no difference in overall survival by extent of thyroidectomy in the propensity score matched population and the total study population (hazard ratio for less-than-total thyroidectomy 0.82, 95% confidence interval 0.52-1.29; hazard ratio for less-than-total thyroidectomy 1.03, 95% confidence interval 0.71-1.48, respectively). Similarly, there were no differences in thyroid cancer-specific survival by extent of thyroidectomy. None of the different risk groups showed differences in overall survival by surgical extent, although total thyroidectomy improved overall survival in older females with larger tumors. The proportion of papillary thyroid cancer patients who received a total thyroidectomy was 80% or greater regardless of risk group classification. CONCLUSION Total thyroidectomy had no survival advantage over less-than-total thyroidectomy in Korean papillary thyroid cancer patients except in a specific high-risk group. 80% or more of low-risk papillary thyroid cancer patients received a total thyroidectomy. These results suggest that further patient-centered treatment which considers both quality of life and clinical outcome is needed.

Abstract
BACKGROUND Cervical cancer screening is not recommended for women who underwent hysterectomy with no history of cervical intraepithelial neoplasia (CIN) of grade 2 or higher. We aimed to determine the cervical cancer screening rate in Korean women who underwent hysterectomies and compare it to that in women with intact uteri. METHODS We used data from the 2014-2016 Korean National Cancer Screening Survey; 6807 women aged 30-74 years were included in the study. Participants were asked about their experiences with cervical cancer screening, hysterectomy status, and other variables associated with cancer screening. RESULTS The screening rates among women who have undergone a hysterectomy vs. those who have not during the past 2 years were 61.8% (95% confidence interval [CI], 58.8-64.9) and 64.7% (95% CI, 64.1-65.3), respectively. Among younger women (30-44 years) and women with a family history of cancer, those with hysterectomies showed a higher cervical cancer screening rate than those without (77.8% vs. 57.1% and 75.0% vs. 67.1%, respectively). CONCLUSIONS Despite available evidence and clinical recommendations, a considerable number of Korean women who no longer have a cervix continue to undergo unnecessary cervical cancer screening. It is necessary to identify the exact underlying causes for this phenomenon, and systematic efforts are required to prevent unnecessary screening for women who have undergone a hysterectomy.

Abstract
The toll of inadequate health care is well-substantiated, but recognition is mounting that "too much" is also possible. Overdiagnosis represents one harm of too much medicine, but the concept can be confusing: It is often conflated with related harms (such as overtreatment, misclassification, false-positive results, and overdetection) and is difficult to measure because it cannot be directly observed. Because the U.S. Preventive Services Task Force (USPSTF) issues screening recommendations aimed largely at healthy persons, it has a particular interest in understanding harms related to screening, especially but not limited to overdiagnosis. In support of the USPSTF, the authors summarize the knowledge and provide guidance on defining, estimating, and communicating overdiagnosis in cancer screening. To improve consistency, thinking, and reporting about overdiagnosis, they suggest a specific definition. The authors articulate how variation in estimates of overdiagnosis can arise, identify approaches to estimating overdiagnosis, and describe best practices for communicating the potential for harm due to overdiagnosis.

Abstract
PURPOSE For the target treatment and prevention of women's increased thyroid cancer, we focused on risks of environmental exposure to endocrine disrupting chemicals, particularly bisphenol A (BPA), and its high susceptible exposure-timing, particularly early exposure in lives. MATERIALS AND METHODS Female ICR mice were exposed to BPA in utero and in early life (15, 75, and 300 mg/L of drinking water via pregnant mice and lactation). We identified BPA-responsive proteins in mice thyroid by two-dimensional gel electrophoresis, image analyses, and electrospray ionization quadrupole time-of-flight mass spectrometry. We further analyzed expression of the BPA-responsive proteins in women thyroid cancer patients (n=28). RESULTS We found the altered 17 proteins in BPA dose-dependent manner among the thyroid tissues of offspring mice and identified nine proteins of them, including Anxa6, Atp5b, Hspa5, and Vcp, etc. In addition, we observed the positive association between blood BPA levels and mRNA expression of the ANXA6 and VCP not in normal but thyroid cancer tissues. CONCLUSION Our study provides ANXA6 and VCP as proteomic biomarkers for BPA-early life exposure and their potential for women's thyroid cancer.

Abstract
A thyroid ultrasound examination program has been conducted in the aftermath of the Fukushima Daiichi Nuclear Power Plant accident to address concerns about the increased risk of thyroid cancer similar to those experienced by local residents after the 1986 Chernobyl accident. This is the second-largest thyroid cancer screening in younger age ever, following only that conducted after Chernobyl. As the natural history of thyroid cancer in younger populations is not well characterized, large-scale screening using thyroid ultrasound could result in overdiagnosis, even with careful planning, as has been experienced in South Korea. Awareness regarding the thyroid gland is generally low among residents, who tend to directly associate examination results with radiation exposure and are likely to develop newfound anxiety and feelings of self-condemnation and guilt. We reviewed the dilemma surrounding cancer screening and particularly underscored the need to address psychosocial issues associated with possible overdiagnosis. We modified our approach to address individual and social anxiety induced by results of screening conducted after the Fukushima accident. These findings and our experiences regarding the psychosocial issues related to thyroid examination should assist residents in their lifelong decision making and help them prepare for future disasters.
