Publication date: Available online 23 October 2018Source: Cirugía Española (English Edition)Author(s): Ozgur Ekinci, Sumeyra Emine Boluk, Tunc Eren, Ibrahim Ali Ozemir, Salih Boluk, Artur Salmaslioglu, Metin Leblebici, Orhan AlimogluAbstractBackgroundNodular thyroid disease possesses the potential to harbor malignancy. Our aim was to evaluate the significance of cervical diffusion-weighted magnetic resonance imaging (DW-MRI) for the detection of malignant thyroid nodules.MethodsSixty-five thyroid nodules from 58 patients who had undergone surgery were evaluated. Preoperative parameters, demographic data, ultrasound findings, fine-needle aspiration biopsy results and apparent diffusion coefficient (ADC) values of the nodules at DW-MRI were compared with the results from postoperative pathology examinations.ResultsThe “benign group” included 50 (76.9%) nodules, while 15 (23.1%) nodules constituted the “malignancy group”. Minimum, maximum and mean ADC values of the nodules were significantly lower in the malignancy group (P

Authors: Demers AA, Brenner DR, Smith L, Shaw A Abstract Examining incidence trends of all cancers combined in order to understand cancer trends can be misleading, as patterns can vary across individual cancer types. This paper highlights findings on trends over time from Canadian Cancer Statistics 2019, as measured by the annual percent change (APC) of age-standardized incidence rates. Among the results were a recent increase in thyroid cancer in males (APC: 6.4%, 1997-2015), as well as decreases in prostate cancer (APC: -9.1%, 2011-2015) and cervical cancer (APC: -3.3%, 2010-2015).

Although well-differentiated papillary thyroid cancer may remain indolent, lymph node metastases and the recurrence rates are approximately 50% and 20%, respectively. No current biomarkers are able to predict metastatic lymphadenopathy and recurrence in early stage papillary thyroid cancer. Hence, identifying prognostic biomarkers predicting cervical lymph-node metastases would prove very helpful in determining treatment.

We reported previously that the cranio-caudal approach is extremely useful for endoscopic complete lymph node dissection around the trachea. In 2014, we upgraded the initial BAVANS for better maneuverability and quality of lymph node dissection. A new high-tech rigid endoscope with a variable viewing direction (EndoCAMeleon ™), has enabled us to reduce the camera port in the anterior neck while keeping the easy maneuverability and the same quality of central lymph node dissection (LND) as with the initial BAVANS. Endoscopic thyroid cancer surgery is now evolving concurrently with new visual technology.

Conclusion: Patients with type 1 DM should be examined for thyroid diseases, and patients with suspected thyroid disease should be evaluated with a thyroid ultrasound. Type 1 DM and PTC coexistence albeit very rare; It should be known that type 1 diabetes can be seen together with thyroid cancer. PMID: 31686641 [PubMed - as supplied by publisher]

ConclusionsThyroid carcinoma arising in struma ovarii or mature cystic teratoma should prompt clinical evaluation and imaging of the thyroid given the possibility of synchronous primaries, metastases, and recurrence.

Radioiodine refractory (RAIR) is the major cause of thyroid cancer-related death. In order to avoid needless Radioiodine (RAI) therapy, recognizing the RAIR cases in time is important for the patients to obtain more time for the effective therapy. Evaluate the ultrasound features of cervical metastatic lymph node in patients with RAIR differentiated thyroid cancer (DTC). Seventeen adult patients with histologically confirmed locally advanced or metastatic RAIR-DTC were prospectively enrolled. The ultrasound (US) characteristics of cervical lesions in patients with the RAIR-DTC were compared with cervical lymph node metas...

CONCLUSIONS: Within an Italian medical context, active surveillance appears to be a feasible and safe alternative to immediate surgery in healthy mPTC patients. Only 3% of mPTC demonstrated disease progression during a median follow-up of 19 months (range 6-54) and importantly demonstrated excellent outcomes after surgical intervention in a short term follow up.

Abstract AP-1 is a dimeric complex that is composed of JUN, FOS, ATF and MAF protein families. FOS-related antigen 1 (FRA1) which encoded by FOSL1 gene, belongs to the FOS protein family, and mainly forms an AP-1 complex with the protein of the JUN family to exert an effect. Regulation of FRA1 occurs at levels of transcription and post-translational modification, and phosphorylation is the major post-translational modification. FRA1 is mainly regulated by the mitogen-activated protein kinases signaling pathway and is degraded by ubiquitin-independent proteasomes. FRA1 can affect biological functions, such as tumor...
