Importance: Controversy exists around the American Joint Committee on Cancer (AJCC) TNM staging system for medullary thyroid cancer (MTC). Because of the rarity of the disease and limited available data, the staging system for MTC has been largely extrapolated from staging for differentiated thyroid cancer. Objectives: To evaluate how well the current (seventh and eighth editions) AJCC TNM staging system correlates with survival for patients with MTC and to suggest a possible revision...

To assess the prognostic value of lymph node ratio (LNR) in patients with stage IV thyroid cancer based on the Surveillance, Epidemiology, and End Results (SEER) database. A total of 4,940 eligible patients were included for the analysis. Kaplan-Meier survival analysis and Cox proportional hazard regression were used to reveal the effect of LNR on overall survival (OS) and disease specific survival (DSS). The optimal cut-off value of LNR for predicting OS and DSS was determined by the time-dependent Receiver Operating Characteristic analysis...

Despite the increase in thyroid cancer incidence among adolescents and young adults (AYAs), this group has received limited attention. We reviewed the epidemiology and challenges of thyroid cancer care among AYAs, and proposed a research agenda to improve their care. Thyroid cancer is the most common cancer in American adults 16-33 years of age. AYAs with thyroid cancer face challenges including overdiagnosis reduced healthcare access and inconsistent care. Successful treatment of these patients results in additional challenges due to ongoing side effects of treatment as well as lasting impacts on their quality of life...

BACKGROUND: Epidemiologic data in volcanic areas suggest that environmental factors might be involved in the increase of thyroid cancer (TC) incidence. Recent reports indicate that several heavy metals and metalloids are increased in volcanic areas. This study aims to evaluate the combined effect of three of these elements Boron (B), Cadmium (Cd), and Molybdenum (Mo) - all increased in the volcanic area of Mt. Etna, in Italy - on thyroid tumorigenesis in the rat. METHODS: Female Wistar rats prone to develop thyroid tumors by low-iodine diet and methimazole treatment received ad libitum drinking water supplemented with B, Cd, and Mo at concentrations in the range found in the urine samples of residents of the volcanic area...

Hepatitis C virus (HCV) is known for its oncogenic potential and has been found to be associated with hepatocellular carcinoma (HCC) and non-Hodgkin lymphoma. It has also been postulated that HCV may play a role in the development of other extrahepatic solid tumors of other organs of the body since it has been isolated from the vessel wall, kidney, and oral mucosa. In this article, we have reviewed epidemiological studies that have been done to look into the relationship of HCV with nonliver solid cancers of the pancreas, thyroid, renal, oral cavity, breast, and lung and nonpancreatic gastrointestinal cancers...

PURPOSE: Whether cardiovascular disease (CVD) risk differs according to race and cancer type among survivors of childhood or young adulthood cancers is unknown. METHODS: Data from the years 1973-2011 were analyzed using the Surveillance, Epidemiology, and End Results (SEER) registries. Cases were categorized by ICD-0-3/WHO 2008 Adolescent and Young Adult classification. CVD death was determined by ICD-10 codes for diseases of the heart, atherosclerosis, cerebrovascular diseases, or other diseases of the arteries...

Reclassification of non-invasive encapsulated follicular variant of papillary thyroid carcinoma (EFV-PTC) into non-invasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) has significant impact for patients and clinicians. It was estimated that this reclassification could potentially affect more than 45,000 patients worldwide annually (around 20% of thyroid carcinoma), who will not be labeled as having cancer. Our experience from Asian grounds indicates that NIFTP is extremely rare in local practice...

BACKGROUND: Thyroid cancer affects over ½ million people in the U.S. and the incidence of thyroid cancer has increased worldwide at a rate higher than any other cancer, while survival has remained largely unchanged. The aim of this research was to develop, calibrate and verify a mathematical disease model to simulate the natural history of papillary thyroid cancer, which will serve as a platform to assess the effectiveness of clinical and cancer control interventions. METHODS: Herein, we modeled the natural pre-clinical course of both benign and malignant thyroid nodules with biologically relevant health states from normal to detected nodule...

Context: As thyroid cancer incidence rises, more patients undergo thyroid surgery. Although post-operative complication rates have been reported in single institution studies, population-based data is limited. Objective: Determine thyroid cancer surgery complication rates and identify at-risk populations. Design/Setting/Patients: Using the Surveillance, Epidemiology, and End Results-Medicare database, we evaluated general complications within 30 days and thyroid surgery specific complications within one year in 27,912 patients who underwent surgery for differentiated or medullary thyroid cancer between 1998-2011...

OBJECTIVES: The association between breast cancer (BC) and thyroid disorders has been widely explored with unclear results. Mammographic density (MD) is one of the strongest risk factor for BC. This study explores the relationship between thyroid diseases and MD in Spanish women. MATERIALS & METHODS: This cross-sectional study covered 2883 women aged 47-71 years participating in 7 BC screening programs in 2010. They allowed access to their mammograms, had anthropometrical-measures taken, and answered a telephonic epidemiological interview which included specific questions on thyroid diseases...

Importance: Incidental thyroid nodules are defined as nodules originally detected in a patient with no thyroid-related clinical symptoms, examination findings, or suspected thyroid disease. Medical imaging for diseases in the neck, chest, and spine is a common source of incidental thyroid nodules. They are easily detected but poorly characterized. The next step is to decide whether the incidental thyroid nodule should be further evaluated with ultrasonography. Observations: Indiscriminate workup of incidental thyroid nodules with ultrasonography is not cost-effective and is potentially harmful...

Geena X Wu, Rebecca A Nelson, Jae Y Kim, Dan J Raz
BACKGROUND: Patients with previous malignancies could be at increased risk of non-small cell lung cancer (NSCLC). However, the extent of the risk is unknown for many cancer types; thus, it is unclear who might benefit from screening. MATERIALS AND METHODS: The Surveillance, Epidemiology, and End Results data set from 1992 to 2012 was used to identify patients with previous malignancies who received a diagnosis of NSCLC ≥ 6 months after their initial cancer diagnosis...

BACKGROUND: Sub-Saharan African-born blacks (ABs) are one of the fastest-growing populations in the United States. However, to the authors' knowledge, data regarding the cancer burden in this group are lacking, which would inform targeted cancer prevention and control. METHODS: The authors calculated age-standardized proportional incidence ratios (PIRs) comparing the frequency of the top 15 cancers in ABs with that of US-born non-Hispanic blacks (USBs) by sex and region of birth using incidence data for 2000 through 2012 from the Surveillance, Epidemiology, and End Results (SEER 17) program...
