Utility of Preoperative Ultrasonography in Transferred Patients with Suspicious Malignancy on Ultrasonography-Guided Fine-Needle Aspiration Cytology of Thyroid Nodules: A Single-Center Retrospective Study.

CONCLUSIONS In the transferred patients with a malignant cytology, preoperative US might be helpful to detect false-positive cytology cases. PMID: 31522188 [PubMed - in process]

Authors: Li H, Zhao J, Zhang J, Wang C, Li M, Wu S, Su Z, Pan Q Abstract A total of 15-30% of thyroid nodules that are evaluated by fine-needle aspiration are not clearly determined to be benign or malignant. Gene mutation analysis is recommended for the evaluation of thyroid nodules using clinical guidelines. The detection of circulating tumor DNA (ctDNA) has the potential to aid in the screening, diagnosis and prediction of thyroid cancer prognosis, and can be used when tissues are difficult to obtain. In the present study, whole-exome sequencing (WES) was performed on tumors and matched normal tissues from 10 pa...

Conclusion: PSCCT is a rare but aggressive malignancy of the head and neck. Histopathologic and immunohistochemical evaluations are essential for diagnosis. While locoregional surgery and radiation therapy may improve the length of survival, the prognosis of patients with PSCCT is poor. Physicians should be mindful of this unique but deadly disease process, as early diagnosis and rapid treatment initiation are essential to optimize treatment outcomes. PMID: 31528145 [PubMed]

Conclusion: Diagnostically, we almost meet the international standards of designating cases with AUS/FLUS (Bethesda category III) and approximate the risk of malignancy. However, the clinical management's guidelines should be followed to decrease the risk of unnecessary surgeries and their complications. There is a statistically significant correlation between the age and gender with the final histopathology report, respectively.

In this study, we summarize AUS/FLUS diagnosed cases from thyroid fine needle aspirations in our center from 2015 to 2017 to explore the impact of BRAF V600E detection on the cytopathological diagnosis of PTC. BRAF V600E detection could significantly reduce the AUS/FLUS diagnosis rates from 11.59 to 8.42% when all BRAF V600E-mutated AUS/FLUS cases were diagnosed as conforming to PTC (20.01 to 19.13% in 2016 and 10.92 to 7.93% in 2017, respectively). The AUS/M rates decreased from 0.67 to 0.64 in 2016 and from 0.33 to 0.23 in 2017. We further discuss a case with a single BRAF V600E cytological mutant lacking a postoperative...

Authors: Asmelash D, Tesfa K, Biadgo B Abstract Background: Thyroid dysfunction is the most common endocrine disorder in clinical practice, and about half of the population with thyroid dysfunction remains undiagnosed. There is a fairly wide spectrum of thyroid dysfunction, which can be identified by patterns of thyroid function test results. The prevalence of thyroid dysfunction among the population varies in different studies. Methods: A cross-sectional study was conducted from February 8th to April 8th, 2017, among patients who requested for the thyroid function test in an endemic goiter area at the Gondar H...

AbstractRET proto-oncogene (RET) mutations were proved to be related to the development of medullary thyroid carcinoma (MTC). We aimed to analyze the role ofRET mutations in cervical lymph node metastasis in patients with MTC. Forty-nine patients with preoperatively diagnosed MTC by fine-needle aspiration cytology (FNAC) who underwent bilateral total thyroidectomy with cervical lymphadenectomy were included. PostoperativeRET gene test and pathological analysis were performed with the surgical specimens; serum calcitonin (Ctn) and carcinoembryonic antigen (CEA) levels were tested pre- and postoperatively, to evaluate the as...

This study reviewed the medical records of 996 LLNs from 858 patients with suspicious thyroid nodules or after thyroidectomy from January 2013 to January 2016. All patients took US-FNA. The US characteristics and the malignancy rate of LLNs classified into group A and group B based on size were analyzed and compared (group A, ≥6 mm; group B, 0.005) in multiple regression analysis, whereas the malignancy rate in the large LLNs (286/425; 67.3%) was slightly higher than that in the small LLNs (338/571; 59.2%) (P = 0.01). However, no significant difference was observed between the groups in terms of calcification, absence o...

We report a unique case of nodal MCC in head and neck lesions with an unknown primary. A 70-year-old woman was admitted to our department with a right submandibular mass. Fine needle aspiration biopsy was performed and indicated malignancy. F-18-fluorodeoxyglucose positron emission tomography (PET) demonstrated abnormal accumulation in the right submandibular lymph node, right palatine tonsil, and right thyroid gland. For diagnostics and treatment, bilateral selective neck lymph node dissection, right tonsillectomy, and right thyroidectomy were performed. Histopathological examination revealed that most parts of the subman...

CONCLUSIONS: Because of the association between FAP or colon cancer with multifocal CMV-PTC, we confirm that an analysis of APC gene mutation and colonoscopy should be carried-out in these patients when multiple thyroid tumors are found. PMID: 31469036 [PubMed - as supplied by publisher]
