Background
Telomerase reverse transcriptase (TERT) promoter mutations are associated with increased recurrence and mortality in patients with thyroid carcinoma. Previous studies on TERT promoter mutations were retrospectively conducted on a limited number of patients.
Methods
We prospectively collected data on all consecutive patients who underwent thyroid carcinoma surgery between January 2019 and December 2020 at the Samsung Medical Center, Seoul, Korea. We included 2,092 patients with thyroid carcinoma.
Results
Of 2,092 patients, 72 patients (3.4%) had TERT promoter mutations. However, the frequency of TERT promoter mutations was 0.5% in papillary thyroid microcarcinoma (PTMC) ≤1 cm and it was 5.8% in papillary thyroid carcinoma (PTC) >1 cm. The frequency of TERT promoter mutations was significantly associated with older age at diagnosis (odds ratio [OR], 1.12; P<0.001), larger primary tumor size (OR, 2.02; P<0.001), and aggressive histological type (OR, 7.78 in follicular thyroid carcinoma; OR, 10.33 in poorly differentiated thyroid carcinoma; OR, 45.92 in anaplastic thyroid carcinoma; P<0.001). Advanced T stage, advanced N stage, and distant metastasis at diagnosis were highly prevalent in mutated thyroid cancers. However, initial distant metastasis was not present in patients with TERT promoter mutations in PTMC. Although the C228T mutation was more highly detected than the C250T mutation (64 cases vs. 7 cases), there were no significant clinicopathological differences.
Conclusion
This study is the first attempt to investigate the frequency of TERT promoter mutations in a real-world setting. The frequency of TERT promoter mutations in PTC was lower than expected, and in PTMC, young patients, and female patients, the frequency was very low.

Background
Bone mineral density (BMD) testing is indicated for women aged 65 years, but screening strategies for osteoporosis are controversial. Currently, there is no study focusing on the BMD testing interval in Asian populations. The current study aimed to evaluate the estimated time interval for screening osteoporosis.
Methods
We conducted a study of 6,385 subjects aged 50 years and older who underwent dual-energy X-ray absorptiometry screening more than twice at Samsung Medical Center as participants in a routine health checkup. Subjects were divided based on baseline T-score into mild osteopenia (T-score, <–1.0 to >–1.5), moderate osteopenia (T-score, ≤–1.5 to >–2.0), and severe osteopenia (T-score, ≤–2.0 to >–2.5). Information about personal medical and social history was collected by a structured questionnaire.
Results
The adjusted estimated BMD testing interval for 10% of the subjects to develop osteoporosis was 13.2 years in mild osteopenia, 5.0 years in moderate osteopenia, and 1.5 years in severe osteopenia.
Conclusion
Our study provides extended information about BMD screening intervals in Asian female population. Baseline T-score was important for predicting BMD screening interval, and repeat BMD testing within 5 years might not be necessary in mild osteopenia subjects.

Background

Previous studies have suggested that recombinant human thyroid stimulating hormone (rhTSH) stimulation is an acceptable alternative to thyroid hormone withdrawal (THW) when radioiodine remnant ablation is planned for thyroid cancer treatment, based on superior short-term quality of life with non-inferior remnant ablation efficacy. This study evaluated the cost-effectiveness of radioiodine remnant ablation using rhTSH, compared with the traditional preparation method which renders patients hypothyroid by THW, in Korean perspective.

Methods

This economic evaluation considered the costs and benefits to the Korean public healthcare system. Clinical experts were surveyed regarding the current practice of radioiodine ablation in Korea and their responses helped inform assumptions used in a cost effectiveness model. Markov modelling with 17 weekly cycles was used to assess the incremental costs per quality-adjusted life year (QALY) associated with rhTSH. Clinical inputs were based on a multi-center, randomized controlled trial comparing remnant ablation success after rhTSH preparation with THW. The additional costs associated with rhTSH were considered relative to the clinical benefits and cost offsets.

Results

The additional benefits of rhTSH (0.036 QALY) are achieved with an additional cost of Korean won ₩961,105, equating to cost per QALY of ₩26,697,361. Sensitivity analyses had only a modest impact upon cost-effectiveness, with one-way sensitivity results of approximately ₩33,000,000/QALY.

Conclusion

The use of rhTSH is a cost-effective alternative to endogenous hypothyroid stimulation prior to radioiodine ablation for patients who have undergone thyroidectomy in Korea.

AbstractAbstract PDF
BACKGROUND
Follicular thyroid tumors harbor several genetic alterations such as RAS mutations and PAX8/PPARgamma rearrangement. The aims of our study were to investigate the prevalence of RAS mutations and PAX8/PPARgamma rearrangement in follicular thyroid tumors and to correlate RAS mutations and/or PAX8/PPARgamma rearrangement with clinicopathologic features in Korean patients with follicular thyroid carcinomas. METHODS: RAS mutations were investigated by polymerase chain reaction and DNA sequencing in surgical specimens of 37 follicular thyroid carcinomas (FTCs) and 16 follicular thyroid adenomas (FTAs). PAX8/PPARgamma rearrangement was analyzed by fluorescent in situ hybridization in surgical specimens of 31 FTCs and 13 FTAs. RESULTS: RAS mutations were detected in 30% (11 of 37) of FTCs and 19% (three of 16) of FTAs. Three of 11 FTC patients with RAS mutations died of thyroid cancer, but none of the 26 FTC patients without RAS mutations. PAX8/PPARgamma rearrangement was found in 10% (three of 31) of FTCs, but in none of the 13 FTAs. All three FTC patients with PAX8/PPARgamma rearrangement remained in complete remission during follow-up. There were no FTC patients with both RAS mutations and PAX8/PPARgamma rearrangement. CONCLUSION: The prevalence of RAS mutations in our series of follicular tumors was similar to previous studies. The frequency of PAX8/PPARgamma rearrangements in our group of FTC was lower than previous western reports, but higher than Japanese reports. RAS mutations may be associated with hematogeneous metastasis and poor survival while PAX8/PPARgamma rearrangement may be related to more favorable prognosis in Korean patients with FTCs.

AbstractAbstract PDF
BACKGROUND
Studies on the clinicopathological characteristics and prognostic factors of medullary thyroid carcinoma (MTC) in Korea are very rare. METHODS: We enrolled 56 MTC patients who underwent surgery at Samsung Medical Center from 1995 to 2006. We analyzed their gender, age at diagnosis, the pathologic findings, the TNM stage, the association with multiple endocrine neoplasia (MEN), RET protooncogene mutation and the, serum basal calcitonin levels before and after the surgery. We investigated the overall survival and the prognostic factors. RESULTS: The mean age at diagnosis was 46 years and the male/female ratio was 1:2.7. Fine needle aspiration cytology detected 61% of the MTC. The mean tumor size was 2.6 cm (range: 0.2-9.0 cm). Fifty-two percent of patients had the TNM stage more than III at the time of diagnosis. Distant metastasis was found in 5.3% (3/56) of the patients, either at the time of diagnosis or during the follow-up period. Hereditary MTC comprised of 23% of the patients and the disease developed at a younger age (38 years vs. 48 years, respectively, P < 0.05) with more bilaterality. RET protooncogene mutations were found in 27% (9/33) of the patients and most of them were in codon 634. After the primary surgery, the serum basal calcitonin levels were persistently elevated over 13 ng/L in 49% of the patients. The overall 5-year survival rate was 95.5%. Tumor size and distant metastasis were the significant prognostic factors for survival by univariate analysis (P < 0.05). CONCLUSION: There were no significant differences in the clinicopathological characteristics of MTC and survival in Korea compared to those of the Western countries.

AbstractAbstract PDF
BACKGROUND
Both thyroid and breast cancers occur more frequently in women than in men. Some suggest that estrogen plays a role in the tumorigenesis of both cancers. The aim of this study was to identify the prevalence and clinico-pathologic characteristics of primary thyroid cancer in patients with breast cancer. METHODS: We retrospectively obtained clinical and pathologic data for 112 patients diagnosed with both thyroid and breast cancer from a single center. Patients with thyroid cancer were grouped according to the chronological sequence of tumor diagnosis. When thyroid and breast cancers were diagnosed within 12 months of each other, they were considered to have been diagnosed simultaneously. Female patients who had only papillary thyroid cancer were used as a historic control. RESULTS: Between 1994 and 2008, 7,827 patients at our hospital were diagnosed with breast cancer and 6,571 patients with thyroid cancer. There were 112 patients who had both thyroid and breast cancer. All thyroid cancers (111/112) except one hurthle cell cancer were papillary thyroid cancers. Average tumor size of thyroid cancer cases diagnosed 1) after or 2) simultaneously with the diagnosis of breast cancer was significantly lower than that for 3) thyroid cancer cases found before breast cancer diagnosis or 4) historical controls with papillary thyroid cancer [sizes (in cm), respectively, were: 1) 0.9 +/- 0.6 2) 0.9 +/- 0.5 vs 3) 1.4 +/- 0.9 4) 1.4 +/- 1.1, P < 0.05]. No patients had distant metastases and there were no statistically significant differences in known risk factors for recurrence and survival of patients with thyroid cancer. CONCLUSION: Thyroid cancer is the most common second primary malignancy in patients with breast cancer and most of them are papillary thyroid cancers. There are no differences in risk factors for tumor recurrence and patient survival compared with those with conventional papillary thyroid cancer except for differences in tumor size. These difference in size may reflect an increase in medical surveillance in patients after they are diagnosed with breast cancer.

AbstractAbstract PDF
BACKGROUND
The outcomes of papillary thyroid carcinoma (PTC) variants have been described in a limited number of studies. The purpose of this study was to compare patient outcomes of PTC variants with those of patients with classic PTC. METHODS: A single-institution retrospective analysis was performed to review 2,366 patients with classic PTC and 159 patients with PTC variants diagnosed between 1994 and 2004. PTC variant patients were divided into two groups, favorable (n = 119, 119 follicular variants including 14 encapsulated follicular variants) and aggressive (n = 40, including 13 diffuse sclerosing, 11 tall cell, six solid, six oncocytic, and four columnar cell variants). RESULTS: Compared with classic PTC, the favorable and aggressive variants had a significantly larger tumor size (P<0.001). The favorable variants had significantly lower rates of bilaterality, multifocality, extrathyroidal invasion, cervical lymph node metastasis, stage III and IV disease, and greater male to female ratio (P<0.05). In particular, the encapsulated follicular variant showed no bilaterality, multifocality, extrathyroidal invasion, lymph node metastasis, and distant metastasis. However, the disease-specific survival and recurrence-free survival of patients with favorable PTC were not different from the patients with classic PTC. The aggressive variants had significantly higher rates of bilaterality and cervical lymph node metastasis compared to the classic PTC (P<0.05). They had significantly reduced disease-specific survival and recurrence-free survival rates (P<0.01). CONCLUSIONS: Knowledge of the nature of PTC variants, especially aggressive types, is important in predicting patient outcome and providing appropriate treatment. Further study is needed to better understand PTC variants.

BACKGROUND
Surgical excision is the only effective treatment of medullary thyroid carcinoma (MTC) and there is no certain treatment for recurrence or distant metastasis. Materials that influence MTC cell proliferation were recently reported. Presently, we evaluated the influence of dexamethasone, somatostatin, progesterone, estradiol-17-beta, forskolin and gastrin on MTC cell proliferation and calcitonin secretion. METHODS: Genomic DNA was extracted and sequenced from untreated thyroid TT cells and cells treated with 10-5~10-10 M dexamethasone, somatostatin, progesterone, estradiol-17-beta, forskolin or gastrin, and cultured for 1~6 days. Cell proliferation was assessed using a BrdU assay at days 1, 2, 3, and 6. Calcitonin in the culture medium from dexamethasone-treated TT cells was measured at days 1~3. RESULTS: Replacement of cysteine with tryptophan at codon 634 of exon 11 was evident in treated TT cells. There was no significant difference in cell proliferation at days 1~3 in cells treated with somatostatin, progesterone, estradiol-17-beta, gastrin and forskolin, while proliferation was inhibited in dexamethasone-treated cells in a concentration-dependent manner from 10-5~10-8 M with no inhibition evident at 10-10 M. Calcitonin levels in 10-5~10-8 M dexamethasone-treated cells were decreased. CONCLUSION: Dexamethasone is a potentially useful compound to suppress MTC cell proliferation. Further studies are necessary to explore this potential further prior to clinical use.

AbstractAbstract PDF
Hyalinizing trabecular tumor is a rare benign thyroid tumor first described by Carney et al. in 1987. The tumor is characterized by an encapsulated nodule, trabecular arrangement of polygonal, oval, elongated cells, and hyalinized stroma. It is easily confused with papillary thyroid carcinoma or medullary thyroid carcinoma on surgical and cytologic specimens. A 45-year-old man presented with an incidentally detected left thyroid mass. Fine needle aspiration was performed and papillary thyroid carcinoma was suspected. However, the surgical specimen revealed a hyalinizing trabecular adenoma. We present this hyalinizing trabecular adenoma case to share our experience with physicians and specialists.

AbstractAbstract PDF
BACKGROUND
RET/PTC rearrangement and mutations of BRAF and ras are well-known oncogenes involved in the pathogenesis of papillary thyroid carcinoma (PTC). The prevalence of RET/PTC rearrangement and BRAF mutations were 0~13% and 66~83% in Korean patients with PTC, respectively. We evaluated the prevalence of ras mutations in surgical specimens of PTC, and we compared them with the patients' clinical features. SUBJECTS AND METHODS: We included the surgical specimens of 49 PTCs and a few follicular thyroid carcinomas (FTCs) and follicular adenomas (FAs) as positive controls. Polymerase chain reaction, single strand conformation polymorphism and direct sequence analysis were consecutively performed to detect ras mutations. RESULTS: No mutations of the ras oncogenes were detected in 49 PTCs. However, heterozygous mutations of the ras oncogenes were found in a FTC and FA as positive controls, respectively. CONCLUSION: These findings suggested that ras mutation is not or rarely related to the tumorigenesis of PTCs in Koreans. Therefore, BRAF mutations and RET/PTC rearrangement, rather than ras mutation, might contribute the development of PTC in Koreans.
