Chemokines and immunomodulatory factors involve in tumor development. Papillary thyroid carcinoma (PTC) is considered to start from dendritic cell infiltration and then produce immunomodulatory factors. In this study, CXCR4 and PD-L1 biomarkers were used to explore their prognostic role in PTC survival. Confocal microscopy detected the transfection efficiency in tumor cells. 42 PTC patients and thyroiditis patients (control) were enrolled to measure the expressions of CXCR4 and PD-L1. Multi-factor analysis analyzed the effect of combined CXCR4 and PD-L1 expression on ROC. The two groups had no differences in the baseline characteristics. CTXCR4 and PD-L1 level in PTC patients was significantly higher than control. CXCR4 was lowly expressed in thyroid cancer tissue and PD-L1 was highly expressed in serological samples. Compared with single measurement, the combined detection of CXCR4 and PD-L1 showed more ROC area. In conclusion, reduced CXCR4 and increased PD-L1 level is found in thyroid cancer and their level might be used as predictive markers for PTC to improve the curative effect.

Abstract Thyroid cancer is the second most common malignancy among females in Saudi Arabia, with Papillary thyroid carcinoma (PTC) accounting for 80-90%. The Kruppel-like factor 5 (Klf5) is a transcription factor that play a critical role in cell transformation, proliferation and oncogenesis. Immunohistochemical analysis of KLF5 was performed in 1219 PTC cases. KLF5 over-expression was noted in 65.1% (793/1219) of PTCs, and was significantly associated with tall-cell variant (p <0.0001), extrathyroidal extension (p = 0.0003), lymph node metastasis (p < 0.0001) and stage IV tumors (p < 0.0001). Significant association was also noted with HIF-1α over-expression (p = 0.0492). Interestingly, KLF5 over-expressing tumors showed poor disease-free survival (p = 0.0066). Functional studies in PTC cell lines showed that KLF5 co-immunoprecipitated with HIF-1α. Knockdown of KLF5 decreased the expression of HIF-1α while KLF5 was not affected by HIF-1α inhibition, suggesting that KLF5 is a functional upstream of HIF-1α. Down-regulation of KLF5 using specific inhibitor, ML264 or siRNA inhibited cell invasion and migration. In addition, treatment of PTC cell lines with ML264 resulted in inhibition of proliferation and induction of apoptosis in a dose-dependent manner. Furthermore, silencing of KLF5 significantly decreased the self-renewal ability of spheroids generated from PTC cells. Our findings confer that KLF5 may be a potential therapeutic target for the treatment of papillary thyroid cancer.

Abstract BACKGROUND Fatigue among thyroid cancer survivors is an important issue that needs to be appreciated and managed appropriately. Although several studies have reported potential factors that might be related to postoperative fatigue, the associations have yet to be inconclusive. The purpose of the present study was to estimate the prevalence of clinical fatigue in patients with papillary thyroid carcinoma and to reveal predictive factors, including their quality of life. METHODS A cross-sectional survey was conducted on patients with papillary thyroid carcinoma. Patients who underwent non-curative surgery, or those with recurrent or metastatic PTC, or those with other malignancies were excluded. The primary outcome was fatigue measured by the Cancer Fatigue Scale (CFS), and the secondary outcome was quality of life (QoL) quantified using the SF-36 v2. The following explanatory variables were collected; gender, age, employment status, marital status, co-morbidities, time since initial surgery, types of surgery, replacement of thyroid hormone, use of radioactive iodine, and the level of thyrotropin. The prevalence of clinical fatigue was estimated with the cut-off value of 18/19 of the CFS score. Correlations between the CFS score and the explanatory variables were examined using uni-variable analyses as well as multi-variable analysis. RESULTS Three hundred twenty-one patients participated in the survey. Of them, 258 respondents (80%) were female. The median age was 58 years, and the median time from initial surgery was 6.4 years. The mean and the standard deviation of the CFS score were 17.9 and 9.3, respectively (range: 0-48). The prevalence of clinical fatigue was 42% [95%CI: 36-47%]. Among the variables explored, having a job and scores of the mental component summary, the physical component summary, and the role/social component summary of the SF-36 were inversely associated with the CFS score in both uni- and multivariable analyses. CONCLUSION Postoperative fatigue was common in thyroid cancer survivors. Patients with a job and better QoL, in particular, those with good mental health, maybe at low-risk of developing the burden.

Publically available (own) transcriptomic data were re-analyzed to quantify the alteration of functional pathways in the thyroid cancer, establish the gene hierarchy, identify potential gene targets and predict the effects of their manipulation. The expression data were generated from one case of papillary thyroid carcinoma (PTC) and from genetically manipulated BCPAP (papillary) and 8505C (anaplastic) human thyroid cancer cell lines. The study used the genomic fabric perspective that considers the transcriptome as a multi-dimensional mathematical object based on the three independent characteristics that can be derived for each gene from the expression data. We found remarkable remodeling of the thyroid hormone synthesis, cell cycle, oxidative phosphorylation and apoptosis pathways. Serine peptidase inhibitor, Kunitz type, 2 (SPINT2) was identified as the Gene Master Regulator of the investigated PTC. The substantial increase of the expression synergism of SPINT2 with apoptosis genes in the cancer nodule with respect to the surrounding normal tissue (NOR) suggests that its experimental overexpression may force the PTC cells into apoptosis with negligible effect on the NOR cells. The predictive value of the expression coordination for the expression regulation was validated with data from 8505C and BCPAP cells before and after lentiviral transfection with DDX19B.

More aggressive thyroid cancer cells show a higher activity of glycometabolism. Targeting cancer cell metabolism has emerged as a novel approach to prevent or treat malignant tumors. Glucose metabolism regulation effect of metformin in papillary thyroid cancer was investigated in the current study. Human papillary thyroid carcinoma (PTC) cell lines BCPAP and KTC1 were used. Cell viability was detected by CCK8 assay. Glucose uptake and relative gene expression were measured in metformin (0–10 mM for 48 h)-treated cells by 18F-FDG uptake assay and western blotting analysis, respectively. MicroPET/CT imaging was performed to detect 18F-FDG uptake in vivo. After treatment with metformin at 0, 2.5, 5 and 10 mM for 48 h, the ratio of p-AMPK to total AMPK showed significant rising in a dose-dependent manner in both BCPAP and KTC1, whereas p-AKT and p-mTOR expression level were downregulated. 18F-FDG uptake reduced after metformin treatment in a dose-dependent manner, corresponding to the reduced expression level of HK2 and GLUT1 in vitro. Xenograft model of PTC using BCPAP cells was achieved successfully. MicroPET/CT imaging showed that in vivo 18F-FDG uptake decreased after treatment with metformin. Immunohistochemistry staining further confirmed the reduction of HK2 and GLUT1 expression in the tumor tissue of metformin-treated PTC xenograft model. In conclusion, metformin could reduce glucose metabolism of PTC in vitro and in vivo. Metformin, by targeting glycometabolism of cancer cells, could be a promising adjuvant therapy alternative in the treatment modality of advanced thyroid carcinoma.

The most frequent type of thyroid malignancy in children is papillary thyroid carcinoma (PTC), which usually presents as a thyroid nodule, but may also present as a diffuse infiltration with microcalcifications. Herein, we report the case of an uncommon presentation of a PTC in a 7-year-old boy. The child was referred for a goiter with cervical lymphadenopathies. Ultrasonography showed a hypervascularised goiter without microcalcifications but with numerous bilateral cervical nodular formations. A lymph node biopsy revealed metastatic thyroid cancer, hence a total thyroidectomy and complete neck dissection were performed. Histopathology confirmed a PTC. Ablative 131I, 30 mCi was performed 4 months postsurgery. At the end of this treatment, a metastatic lung nodule was identified. Since then, another three ablative 131I treatments have been administered. Thyroid cancers presenting as a diffuse infiltration without microcalcifications are rare. In the presence of lymphadenopathies, thyroid cancer needs to be suspected, even without microcalcifications.

History Of

Thyroid nodules are palpable on up to 7% of asymptomatic patients. Cancer is present in 8% to 16% of those patients with previously identified thyroid nodules. Papillary thyroid carcinoma (PTC) is the most common type of thyroid cancer, accounting for approximately 85% of thyroid cancers. Although most appear as solid nodules on ultrasound imaging, a subset of 2.5% to 6% has cystic components. The presence of cystic changes within thyroid nodules decreases the accuracy of fine needle aspiration (FNA) in the diagnosis of thyroid cancer, given the difficulty of obtaining appropriate cellular content. This becomes a diagnostic and therapeutic challenge. We present a case of a 31-year-old female with a 1-month history of palpitations, fatigue, and night sweats, who underwent evaluation, and was diagnosed with subclinical hyperthyroidism. She presented 4 years later with compressive symptoms leading to repeat FNA, showing Bethesda III-atypia of undetermined significance and negative molecular testing. Thyroid lobectomy revealed PTC with cystic changes. This case is a reminder that patients with hyperfunctioning thyroid nodule should have closer follow-up. It poses the diagnostic dilemma of how much is good enough in the evaluation and management of a thyroid nodule. Early detection and action should be the standard of care.

Papillary thyroid carcinoma is the most common thyroid malignancy, accounting for 80% of all thyroid cancers. The most common presentation of thyroid cancer is an asymptomatic thyroid mass or a nodule. Usually as thyroid enlarges, it extends in to mediastinum. Papillary thyroid carcinoma presentation as multiple true cystic swelling extending from neck to anterior chest wall in subcutaneous plane is not present in the literature. We present a rare case of cystic papillary thyroid carcinoma which is presented as subcutaneous swelling with sinus formation.

Review Of The Literature

We present a case of Warthin-like papillary thyroid carcinoma in a 22-year-old woman and a review of the literature on the topic. The patient had the occasional discovery of a hypoechoic thyroid nodule of approximately 18 mm, characterized by irregular margins, hyperechoic spots, rich intra- and perilesional vascularization, and a suspicious enlarged right laterocervical lymph node. Fine-needle aspiration was performed for both lesions and the diagnosis of papillary thyroid carcinoma without lymph node involvement was made. The patient underwent thyroidectomy and central neck lymphadenectomy without complications. Histopathological examination suggested a Warthin-like papillary carcinoma of the thyroid gland, with all the removed lymph nodes being free of disease. The patient subsequently underwent iodine ablative therapy and she remains free of disease one year after surgery. Warthin-like papillary thyroid carcinoma is a recently described variant of papillary thyroid cancer that is frequently associated with lymphocytic thyroiditis. Morphologically, it resembles Warthin tumors of the salivary glands, with T and B lymphocytes infiltrating the stalks of papillae lined with oncocytic cells. Surgical and postoperative management is identical to that of classic differentiated thyroid cancer, while prognosis seems to be favourable.
