“…Although computed tomography (CT) or US may show high sensitivity and accuracy for ETE; [45,48,49] ETE, tumor size, and whether papillary carcinoma is or not can be directly identified by intraoperative frozen sections although it is not complete. So, the factors identified by intraoperative frozen section may be helpful for deciding the extent of surgery intraoperatively, We consider that therapeutic CLND for patients with clinically involved central or lateral neck lymph nodes should accompany total thyroidectomy to provide clearance of disease from the central neck.…”

“…Preference around preoperative imaging was specifically investigated; ultrasonography is the most sensitive modality for staging lymph nodes but axial imaging (traditionally MRI) 26 may have a role for tumours with suspicion of local disease advancement 27 or in higher risk groups (eg scenario 5).…”

INTRODUCTION This study describes variability of treatment for differentiated thyroid cancer among thyroid surgeons, in the context of changing patterns of thyroid surgery in the UK. METHODS Hospital Episodes Statistics on thyroid operations between 1997 and 2012 were obtained for England. A survey comprising six scenarios of varying 'risk' was developed. Patient/tumour information was provided, with five risk stratified or non-risk stratified treatment options. The survey was distributed to UK surgical associations. Respondent demographics were categorised and responses analysed by assigned risk stratified preference. RESULTS From 1997 to 2012, the Hospital Episode Statistics data indicated there was a 55% increase in the annual number of thyroidectomies with a fivefold increase in otolaryngology procedures and a tripling of cancer operations. Of the surgical association members surveyed, 264 respondents reported a thyroid surgery practice. Management varied across and within the six scenarios, and was not related consistently to the level of risk. Associations were demonstrated between overall risk stratified preference and higher volume practice (>25 thyroidectomies per year) (p=0.011), fewer years of consultant practice (p=0.017) and multidisciplinary team participation (p=0.037). Logistic regression revealed fewer years of consultant practice (odds ratio [OR]: 0.96/year in practice, 95% confidence interval [CI]: 0.922-0.997, p=0.036) and caseload of >25/year (OR 1.92, 95% CI: 1.044-3.522, p=0.036) as independent predictors of risk stratified preference. CONCLUSIONS There is a substantial contribution to thyroid surgery in the UK by otolaryngology surgeons. Adjusting management according to established case-based risk stratification is not widely applied. Higher caseload was associated with a preference for management tailored to individual risk.

“…Other findings suggesting tracheal invasion are deformity of the lumen, focal mucosal irregularity or thickening, and intraluminal mass (Figs. 8 and 9) [ 36 , 38 ] . The esophageal wall is more difficult to evaluate than the trachea because it is usually not distended with air.…”

Imaging of thyroid carcinoma with CT and MRI: approaches to common scenarios

et al. 2013

Computed tomography (CT) and magnetic resonance imaging (MRI) can play an important role in preoperative and post-treatment assessment of thyroid malignancy. The radiologist should be aware of the pathological behavior of thyroid carcinoma, and the characteristic imaging appearance of the primary tumor and metastases. This review describes the approach to imaging thyroid cancer on CT and MRI for four common scenarios: detection of the incidental thyroid nodule, evaluation of thyroid metastases, presurgical imaging for invasive disease, and evaluation for recurrence in the post-treatment neck.

Locally Advanced Thyroid Cancer: Can CT Help in Prediction of Extrathyroidal Invasion to Adjacent Structures?

Abstract: Although the effectiveness is limited by low sensitivity, CT may be a valuable tool for evaluation of extrathyroidal invasion of thyroid cancer to adjacent structures.
