Bronchoscopic management of haemoptysis due to endobronchial metastasis of papillary thyroid carcinoma

We describe a rare case of metastatic papillary thyroid carcinoma resulting in endobronchial involvement diagnosed by bronchoscopic biopsy, and successfully managed with argon plasma coagulation ablation. Metastatic involvement of lung by thyroid cancer is common, although presentation with endobronchial disease is rarely encountered. When it occurs, threats to airway patency by luminal obstruction and haemoptysis may occur, requiring prompt recognition and intervention to avoid hypoxia and asphyxiation. Bronchoscopic evaluation is essential for both diagnosis and intervention. To our knowledge, we describe the first case of endobronchial papillary thyroid carcinoma elucidated using bronchoscopic biopsy followed by definitive management using argon plasma coagulation (APC) ablation.

We described the first Italian experience with Afirma tests in a single Italian institution and assessed the performance of the Afirma test in TIR3B. Moreover, this is a preliminary study to assess the patient response to the offer of Afirma testing. The Afirma test was proposed to 67 patients with thyroid nodules that had yielded TIR3B cytology. Fifty-one patients (76.1%) chose the Afirma test, 25/51 underwent the test but the remaining 26 did not because of cost. A total of 41/67 (61.2%) patients underwent surgery, and 22/41 (53.7%) nodules were carcinomas. Of the 25 tested by Afirma, 9 (36%) were classified as Afirma-su...

ConclusionsIn pediatric total thyroidectomies, central neck dissection and gross extrathyroidal extension were major predictors for overall hypoparathyroidism. Surgeons performing thyroidectomy in such patients should be aware of the relatively high risk, preserve parathyroid tissue to the extent possible, and be conscientious regarding postoperative calcium monitoring and replacement.

ierlorenzo Pallante Anaplastic thyroid carcinoma (ATC) represents one the most aggressive neoplasias in humans, and, nowadays, limited advances have been made to extend the survival and reduce the mortality of ATC. Thus, the identification of molecular mechanism underlying its progression is needed. Here, we evaluated the long non-coding RNA (lncRNA) expression profile of nine ATC in comparison with five normal thyroid tissues by a lncRNA microarray. By this analysis, we identified 19 upregulated and 28 downregulated lncRNAs with a fold change >1.1 or <−1.1 and p-value < 0.05, in ATC samp...

Publication date: Available online 14 January 2020Source: Life SciencesAuthor(s): Zhiyi Feng, Rong Chen, Nanqi Huang, Chaoyuan LuoAbstractLong non-coding RNA (lncRNA) is emerging as an essential player in cancer progression. However, its biological function and clinical implication in papillary thyroid carcinoma (PTC) remain poorly understood. In the current study, we found that a novel lncRNA, ASMTL antisense RNA 1 (ASMTL-AS1), was significantly downregulated in PTC. And its downregulation was positively linked to larger tumor size, advanced clinical stage and unfavorable outcome. Overexpression of ASMTL-AS1 evidently inh...

CONCLUSIONS: The rare frameshift mutation in the TINF2 gene and the associated longer telomere length suggest that dysregulated telomeres could be a mechanism predisposing to PTC and melanoma. DNA coding variants in shelterin genes are rare. Further studies are required to evaluate the roles of variants in shelterin genes in thyroid cancer and melanoma.

n A Abstract Papillary thyroid carcinomas (PTC) account for 90% of human thyroid cancer cases which represent 1% of all cancer cases. They are likely to develop from papillary thyroid microcarcinomas (PTMC) found in up to 36% of healthy individuals due to rare progression events (0.01%). Although the prognosis of PTCs is excellent, 5% to 10% of tumors display an unfavorable outcome. About 45% of PTCs exhibit activating BRAFV600E mutations. Rats of the inbred BD strains postnatally exposed to the carcinogen N-ethyl-N-nitrosourea developed PTMCs which closely resembled their human counterparts judging from their his...
