  • Anaplastic transformation of differentiated thyroid cancer at distant metastatic sites is extremely rare and has a poor prognosis. It usually occurs in the thyroid gland or cervical lymph nodes. Here we report a case of anaplastic transformation arising at multiple distant metastatic sites including the lung, liver, adrenal gland, bone, and lymph nodes in a patient 3 years after total thyroidectomy for follicular thyroid cancer.

  • Monoclonal antibody(TCM-9) against human thyroid cancers have been studied by screening with human thyroid cancers, normal and benign thyroid tissue, and normal human serum protein. A monoclonal antibody(TCM-9) that is known to have strong specificity for human thyroid cancer but not for Graves' disease, adenoma or normal thyroid does not bind to native or mature human thyroglobulin(Tg). We used to TCM-9 antibody by immunohistochemical staining on 5 follicular cancer, 2 follicular adenoma, 1 follicular neoplasm with suspicious invasion, 2 papillary cancer to ascertain being of help in differentiation between follicular carcinoma and adenoma. Reactivity of TCM-9 was observed in follicular carcinoma and papillary carcinoma but not observed in follicular adenoma. Thus TCM-9 is a novel monoclonal antibody against the thyroid cancer.

  • We present a case of a mixed papillary and follicular thyroid cancer in a 45-year-old female presented with palpable mass on anterior neck area for 1 week ago. Neck CT and ultrasonogram revealed small solid masses in the both lobes of the thyroid gland. Thyroid scintigraphy presents as a cold nodule in the right lobe of the thyroid gland and FNA cytology demonstrated papillary thyroid cancer. At the time of operation, small sized solid masses were detected in the both lobes, and no cervical lymph nodes enlargement along the mass. Biopsies of the both mass demonstrated papillary cancer on right lobe and follicular cancer on left lobe. Simultaneous papillary and follicular thyroid cancer is an extremely rare clinical entity. We experienced a case of simultaneous papillary and follicular thyroid cancer, so we report it with a review of some articles.

  • Follicular thyroid cancer(FTC) accounts for about 10-15% of thyroid cancer. Distant metastasis is common, usually to lung, bone and brain. 71-years-old man visited neurosurgery outpatient department. He complained of recent 6kg weight loss, left upper extremity pain with weakness and back pain. The radiologic findings showed multiple bone metastasis including thoracic spine and left scapular resulting from FTC. There was a probable brain metastatic lesion on right temporal fossa. The core biopsy of thyroid and thoracic spine(T11) confirmed metastatic follicular carcinoma. Radioactive iodine therapy and radiotherapy was done following total thyroidectomy. We report a unique case of multiple bone metastasis from follicular carcinoma of thyroid with literature review.

  • Communications at the interface between the apical membrane of follicular cells and the follicular lumen are critical for the homeostasis of thyroid gland. Primary cilia at the apical membrane of thyroid follicular cells may sense follicular luminal environment and regulate follicular homeostasis, although their role in vivo remains to be determined. Here, mice devoid of primary cilia were generated by thyroid follicular epithelial cell-specific deletion of the gene encoding intraflagellar transport protein 88 (Ift88). Thyroid follicular cellspecific Ift88-deficient mice showed normal folliculogenesis and hormonogenesis; however, those older than 7 weeks showed irregularly dilated and destroyed follicles in the thyroid gland. With increasing age, follicular cells with malignant properties showing the characteristic nuclear features of human thyroid carcinomas formed papillary and solid proliferative nodules from degenerated thyroid follicles. Furthermore, malignant tumor cells manifested as tumor emboli in thyroid vessels. These findings suggest that loss-of-function of Ift88/primary cilia results in malignant transformation from degenerated thyroid follicles.

  • Background: Pax8 and peroxisome proliferator-activated receptor gamma 1 gene (Pax8-$PPAR{\gamma}1$) are important factors in tumors. Several studies have suggested that follicular thyroid cancer may arise from Pax8- $PPAR{\gamma}1$ rearrangement. In order to have a better understanding of the association between Pax8-$PPAR{\gamma}1$ rearrangement and follicular thyroid cancer, we conducted the presenmt meta-analysis. Materials and Methods: The information was extracted from PubMed, EMBASE and Web of Science. Statistic analysis was performed with Stata12.0 software. Odds ratios (ORs) were calculated using a fixed-effects model. We also performed heterogeneity and publication bias analyses. Results: Nine studies including 198 follicular thyroid cancer patients and 268 controls were considered eligible. The frequency of Pax8-$PPAR{\gamma}1$ rearrangement was significantly higher in the follicular thyroid cancer group than in the control group, with a pooled OR of 6.63 (95%CI=3.50-12.7). In addition, through subgroup analysis, the OR between Pax8-$PPAR{\gamma}1$ rearrangement and follicular thyroid cancer was 6.04 (95%CI = 3.18-11.5) when using benign tumor tissues as controls. The OR for the method subgroup was 9.99 (95% CI =4.86-20.5) in the RT-PCR. Conclusions: The final results demonstrated that Pax8-$PPAR{\gamma}1$ rearrangement has significant association with follicular thyroid cancer.

  • A 60 years old female patient presented with $8{\times}6\;cm$ sized painless oval mass in the left parietal region. She had left lobectomy of thyroid gland 10 years ago. Cranial CT, MRI, FGD PET-CT showed a solid mass which invaded left parietal bone. After embolization, craniectomy with tumor excision was performed. Histological examination revealed metastatic follicular cancer originated thyroid gland, with vascular and dura invasion. Postoperatively, neck CT showed right thyroid multiple nodules and right level III multiple lymph node enlargement. Thyroid function test was normal, but level of thyroglobulin was high (72ng/ml). So she had right lobectomy of thyroid gland with lymph node dissection under a diagnosis of follicular carcinoma. But histological examination revealed adenomatous hyperplasia and not lymph node metastasis. After operation, she received radioiodine therapy of 150mCi and then the level of thyroglobulin normalized (8.4ng/ml). The patient is under follow-up since she had operation 4 months ago.

  • Purpose: Definite diagnosis of follicular thyroid carcinoma (FTC) is based on the presence of capsular or vascular invasion. To date, no reliable and practical method has been introduced to discriminate this malignant neoplasm from follicular thyroid adenoma (FTA) in fine needle aspiration biopsy material. Matrix metalloproteinase-2 (MMP-2), by degrading extracellular matrix, and caspase-3, by induction of apoptosis, have been shown to play important roles in carcinogenesis and aggressive behavior in many tumor types. The aim of this study was to examine expression of MMP-2 and caspase-3 in thyroid follicular neoplasms and to determine their usefulness for differential diagnosis. Method: Sixty FTAs and 41 FTCs were analysed immunohistochemically for MMP-2 and caspase-3. Result: MMP-2 was positive in 4 FTCs (9.8%), but in none of FTAs, with statistical significance (p= 0.025). Caspase-3 was positive in 30 (50%) of FTAs and in 27 (65.9%) of FTCs. Conclusion: Our results show MMP-2 expression only in FTCs and suggest that this protein may be a useful marker to confirm diagnosis of FTC versus FTA with 100% specificity and 100% predictive value of a positive test. We failed to show any differential diagnostic value for caspase-3 in thyroid follicular neoplasms.

  • Well differentiated thyroid cancers (WDTC), including papillary (80%) and follicular (10%) types, are the most common endocrine cancers globally. Over the last few decades most the diagnosed cases have fallen into low risk categories. Radioactive iodine-131 (RAI) has an established role in reducing recurrence and improving the survival in high risk patients. In patients with primary tumor size <1 cm, RAI is not recommended by many thyroid societies. However, low risk WDTC has been an arena of major controversies, most importantly the role and dose of adjuvant RAI for remnant ablation to minimize chances of recurrence and improving survival. This review is an attempt to update readers about the previous and existing practice based on results of non-randomized trials and evolving trends fueled by recently published randomized studies.
