Purpose. The aim of this study was to evaluate the feasibility of endoscopic thyroidectomy via breast approach for papillary thyroid carcinoma (PTC).Methods. Between March 2008 and March 2013, 34 patients with PTC received endoscopic thyroidectomy (endo group) and 30 patients received conventional open thyroidectomy (open group). Patients in two groups underwent ipsilateral central compartment node dissection. The two groups were compared in terms of patient characteristics, perioperative clinical results, and postoperative complication.Results. The rates of lymph node metastasis in endo group and open group were 23.5% (8/34) and 13.3% (4/30), respectively, without statistically significant difference (P=0.351). The mean number of lymph nodes dissected was 2.4 ± 2.9 in endoscopic group and 2.2 ± 1.9 in open group (P=0.774). During the follow-up period, there was no recurrence or metastatic patients in two groups. All patients received the excellent cosmetic results in endo group, while 25 patients were satisfied with the cosmetic result and 5 were unsatisfied in the open group.Conclusions. The efficacy of endoscopic thyroidectomy via breast approach could be comparable to conventional open thyroidectomy in selected patients with PTC.

Background: A previous genome-wide association study showed that hTERT rs10069690 and rs2736100 polymorphisms were associated with thyroid cancer risk. Objective: This study further investigated the association between increased risk and clinicopathologic characteristics for Papillary Thyroid Carcinoma (PTC) and hTERT polymorphisms rs10069690 or rs2736100 in a Chinese female population. Methods: The hTERT genotypes of 276 PTC patients and 345 healthy subjects were determined with regard to SNPs rs10069690 and rs2736100. The association between these SNPs and the risk of PTC and clinicopathologic characteristics was investigated by logistic regression. Results: We found a significant difference between PTC and rs10069690 (Odds Ratio (OR) = 1.515; P = 0.005), but not between PTC and rs2736100. When the analysis was limited to females, rs10069690 and rs2736100 were both associated with increased risk for PTC in female individuals (OR = 1.647, P = 0.007; OR = 1.339, P = 0.041, respectively). Further haplotype analysis revealed a stimulative effect of haplotypes TC and CA of TERT rs10069690-rs2736100, which increased risk for PTC in female individuals (OR = 1.579, P = 0.014; OR = 0.726, P = 0.025, respectively). Furthermore, the heterozygote A/C of rs2736100 showed significant difference for age (OR = 0.514, P = 0.047). Conclusion: Our finding suggests that hTERT polymorphisms rs10069690 and rs2736100 are associated with increased risk for PTC in Chinese female population and rs2736100 may be related to age. Consistent with US20170360914 and US20170232075, they are expected to be a potential molecular target for anti-cancer therapy.

Background: To compare the abilities of ultrasonography (US) and Computed Tomography (CT) to identify calcifications and to predict probability of malignancy for Papillary Thyroid Carcinoma (PTC) and Papillary Thyroid Microcarcinoma (PTMC). Methods: We reviewed 1008 cases of PTC/PTMC with calcifications reported by pre-operative US, CT, or post-operative pathology. The size of the thyroid nodule was obtained from the US report and the maximum diameter (d) was documented. According to the nodule size (d), the PTC and PTMC groups were each divided into two subgroups, as follows: large PTC group (d ≥ 2 cm), small PTC group (1 cm < d < 2 cm), large PTMC group (0.6 cm ≤ d ≤ 1 cm), and small PTMC group (d < 0.6 cm). Results: In the 1008 patients, the ratio of females to males was 2.29 and the mean age was 40.9 years (standard deviation: 11.7 years). Of the 1008 records, 92.8% were found to have calcifications according to the US report, while 50.4% showed calcifications according to the CT report. This difference between US and CT reports was statistically significant (p < 0.0005). The percentages of US reports showing calcifications were similar for all four PTC and PTMC subgroups (93.7%, 94.3%, 92.1%, and 85.1%, respectively; p = 0.052), while the percentages of CT reports showing calcifications were significantly different among the PTC and PTMC subgroups (62.3%, 52.2%, 45.4%, and 31.3%, respectively; p < 0.0005). As for the prediction of malignancy, US was superior to CT in all four subgroups (large PTC group: 97.1% vs. 54.1%, small PTC group: 94.8% vs. 42.9%, large PTMC group: 97.2% vs. 32.0%, small PTMC group: 95.5% vs. 14.9%; p < 0.0005 for all pairwise comparisons). No significant difference was observed in terms of the ability of US to predict the malignancy of PTC versus PTMC (p = 0.31), while CT showed significant superiority in diagnosing PTC versus PTMC (p < 0.0005). The predictive value of CT for PTC declined as the nodule size decreased (p < 0.05 for all pairwise comparisons). Conclusion: Our results showed that US detected calcifications and predicted the malignancy of all nodule sizes of thyroid papillary carcinoma equally well, while the performance of CT declined with the reduction of nodule size.

Introduction. Lymphocytic infiltration and specific lymphocytes subsets may play important roles in papillary thyroid carcinoma (PTC) progression and prognosis. In this study, we try to understand the influence of131I radioablation on the important lymphocytes subtypes of regulatory T and B cells (Tregs and Bregs).Methods. Peripheral blood mononuclear cells from 30 PTC patients before and after131I therapy, and 20 healthy donors were collected. The expression of Tregs (CD4+CD25+CD127-/low) and B cell (CD5+CD19+) and production and secretion of interleukin 10 (IL-10) were analyzed by FACS and ELISA assay, respectively.Results. For Tregs percentage in peripheral blood lymphocytes, there was no difference between pretreatment and control and between posttreatment and control. Compared with pretherapy, increased Tregs infiltration was noted in posttherapy (P<0.05). Although no difference was between pretreatment and control, compared with these two groups, decreased CD19+and CD5+CD19+B cell percentage in posttreatment was observed (P<0.05). Among these groups, no significant difference was displayed in intracellular IL-10 production and extracellular IL-10 secretion.Conclusions.131I Radioablation increased Tregs and decreased CD19+and CD5+CD19+B cells percentage after treatment. However, it has no effect on IL-10 and lymphocytes in peripheral blood. Therefore, longer follow-up of Tregs and Bregs should be further investigated.
