However, the management of a thyroid nodule with a fine-needle aspiration biopsy classified as Bethesda III, or atypia of undetermined significance/follicular lesion of undetermined significance (AUS/FLUS), remains controversial due to the cytologic heterogeneity and the variability in the reported rates of malignancy. In this review, the history and rationale for the new Bethesda III category is examined, the reported incidence and risk of malignancy from published studies is reviewed and recommendations for management of patients with a thyroid nodule and AUS/FLUS are provided. Recent advances in molecular analysis and their role in the evaluation of patients with AUS/FLUS are also discussed.","PeriodicalId":42691,"journal":{"name":"International Journal of Endocrine Oncology","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2015-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2217/IJE.15.20","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68216883","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Thyroid cancer and insulin resistance: is it important?","authors":"L. Berstein","doi":"10.2217/IJE.15.24","DOIUrl":"https://doi.org/10.2217/IJE.15.24","url":null,"abstract":"Thyroid cancer (TC) has several distinct features. In particular, the median age on disease onset is about 45–50 years, which makes it quite different from hormonerelated tumors such as, for example, endometrial or prostate cancer. The prognosis of TC patients is relatively good in populations with differentiated carcinomas. However, it is worse in patients with medullary and anaplastic TC in particular. Prognosis is also poor in male patients, although in men thyroid cancer is seen thrice less often than in women and on average develops at a more advanced age. Besides female gender, there are other TC risk factors, such as radiation, iodine status of the area and excessive thyroid epithelium stimulation by thyrotropin (thyroid-stimulating hormone; TSH) [1]. Another important issue concerns the gradual increase in TC incidence, which has become particularly evident in the last decade. This increase is mostly due to a higher incidence of papillary carcinomas and could be explained by higher – than earlier – effectiveness of diagnostic methods (apparent increase) as well as greater number of new cases (true increase) [2]. The exact contribution of the latter factors is currently a matter of discussion. Our understanding of factors modulating TC incidence increase and mechanisms able to influence TCs clinical course was recently notably enhanced by the data concerned with a possible role of insulin resistance (IR) state. These ideas rely on two well-known facts, namely, on an established connection between IR and metabolic syndrome, some obesity types, and Type 2 diabetes mellitus incidence [3], and on the knowledge that the rate of the latter pathologies has lately reached ‘epidemic’ scale [4], which could also influence hormone-related cancers, such as TC. This short Editorial is mainly concerned with summarizing the current data on connections between IR and TC. The task is to try and point out some prominent aspects, in which these correlations seem to be most important, and describe possible approaches aimed at preventive as well as therapeutic antihormonal and metabolic interventions in TC patients, not limited only to ‘antithyroid’ (anti-TSH) measures.","PeriodicalId":42691,"journal":{"name":"International Journal of Endocrine Oncology","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2015-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2217/IJE.15.24","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68217064","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Surgery is the only curative therapy for MTC [3]. After surgery, patients with MTC should be assessed regarding the presence of residual disease, the localization of metastases and the identification of progressive disease. Postoperative staging is used to separate low-risk from high-risk patients with MTC [4]. The TNM system utilizes tumor size, extrathyroidal invasion, nodal metastasis and distant spread of cancer. The number of lymph node metastases and involved compartments as well as postoperative serum calcitonin (CTN) and carcinoembryonic antigen (CEA) levels should be documented in addition. The normalization of serum CTN levels postoperatively is associated with an excellent prognosis (10-year survival >95%). In patients with elevated basal serum CTN levels less than 150 pg/ml following thyroid ectomy, persistent or recurrent disease is almost always confined to lymph nodes in the neck. Unfortunately, many patients with MTC who have regional lymph node metastases also have systemic disease and are not cured biochemically despite aggressive surgery, including bilateral neck dissection [3,5]. In patients with higher CTN levels distant metastases are suspected, having a poor prognosis, with only 40% surviving 10 years [6]. If the postoperative serum CTN level exceeds 150 pg/ml patients should be evaluated by imaging procedures including neck and chest CT, contrast-enhanced MRI and ultrasound of the liver, bone scintigraphy, MRI of the bone and PET/CT. One can estimate the growth rate of MTC metastases from sequential imaging studies using response evaluation criteria in solid tumors (RECIST) [7] that document increases in tumor size over time and by measuring serum levels of CTN or CEA over multiple time points to determine the tumor marker doubling time [8,9]. The treatment goals differ depending on the postoperative tumor stage and the parameters of progressive disease [4]. A risk-stratified follow-up with stage-dependent diagnostic approach and therapy is necessary. One of the main challenges remains to find effective adjuvant and palliative options for patients with metastatic disease.
