Molecular Markers in Thyroid Cancer
Thyroid CancerThe purpose of this study is to evaluate how common gene mutations are in benign and malignant thyroid lesions.
Treatment Decision-Making Among Patients Diagnosed With Papillary Microcarcinoma and Their Significant...
Thyroid CancerPapillary MicrocarcinomaThe purpose of this study is to understand more about why some patients choose to have surgery to treat their papillary microcarcinoma (PMC) and others choose to have their papillary microcarcinoma (PMC) regularly watched by their doctor to see if and when they may need surgery (referred to as "active surveillance"). The investigators also hope learn more about what patients and their family members worry about or feel they will gain from surgery or active surveillance.

Circulating Biomarkers to Identify Thyroid Cancer
Thyroid CancerThyroid Cancer2 moreThis study aimed to identify the potential circulating biomarkers of protein, mRNAs, and long non-coding RNAs (lncRNAs) to differentiate the papillary thyroid cancers from benign thyroid tumors. Methods: The study population of 100 patients was classified into identification (10 patients with papillary thyroid cancers and 10 patients with benign thyroid tumors) and validation groups (45 patients with papillary thyroid cancers and 35 patients with benign thyroid tumors). The Sengenics Immunome Protein Array combined data mining approach using the Open Targets Platform was used to identify the putative protein biomarkers, and their expression validated using the enzyme-linked immunosorbent assay. Next-generation sequencing by Illumina HiSeq was used for the detection of dysregulated mRNAs and lncRNAs. The website Timer v2.0 helped identify the putative mRNA biomarkers, which were significantly over-expressed in papillary thyroid cancers than in adjacent normal thyroid tissue. The mRNA and lncRNAs biomarker expression was validated by a real-time polymerase chain reaction.
Thyroid Cancer and Photoacoustic Imaging
Thyroid CancerThyroid NoduleThe aim of this study was to evaluate the usefulness of photoacoustic imaging in thyroid nodules. In addition, we would like to confirm the relationship between the results of photoacoustic imaging and histopathologic findings when thyroid nodules were diagnosed as thyroid cancer.
Modified Cormack Lehane Scores Evaluated by Laryngoscopy During Awake Versus Under General Anesthesia...
Thyroid CancerThyroid Nodule1 moreNowadays, 5-step modified Cormack-Lehane scoring (MCL) system is frequently used in the observation of laryngeal structures by direct laryngoscopy. Upper airways with flexible fiberoptic laryngoscopy are routinely evaluated in patients who are predicted to be difficult intubation, who have undergone head or neck surgery previously and who require vocal cords to be evaluated preoperatively. During this examination patients are awake; so the upper airway and the muscles in the base of the mouth have normal tonus and airway reflexes are active. When general anesthesia is applied to the same patients during direct laryngoscopy, the laryngeal view may not be as clear as awake flexible fiberoptic laryngoscopy, since a tonus loss occurs in the muscles after general anesthesia. The aim of the study is to investigate the relationship between preoperative awake flexible fiberoptic laryngoscopy performed by ear- nose- throat (ENT) physicians in patients undergoing total thyroidectomy, and the MCL score during direct laryngoscopy after general anesthesia in the same patients. Thus, investigators would like to determine the reliability of airway evaluation with preoperative awake flexible fiberoptic laryngoscopy in predicting intubation conditions during tracheal intubation under general anesthesia.
Estimation of Economic Consequences Linked With Different Care Management Pathways of Differentiated...
Thyroid CancerThe incidence of Thyroid Cancer (TC) has increased over the last thirty years, in France and worldwide. This increase is mainly due to good prognosis microPapillary TC (mPTC). Sixty percent of diagnosed cancers are considered as over-diagnosed, leading to an over-treatment of these cases. The increase of diagnosis of mPTC and its treatment inevitably leads to an increase of medical resources consumption and corresponding costs. The primary aim of this study is to estimate the cost related to different care management pathway of TC patient during a lifetime period using a multi-state Markov model. This is a retrospective, observational population based cohort study, using data from a cohort study of TC patients implemented by the ONCOMIP network which initially aimed to perform an audit of clinical practices for the management of TC, and from database of the French social health insurance of Midi-Pyrenees region to calculate observed costs of TC management during 24 months.
Biomarkers to Distinguish Benign From Malignant Thyroid Neoplasm
Cancer of the ThyroidNeoplasms4 moreThis protocol will evaluate microRNA biomarkers in blood and fine-needle aspirate biopsies (FNAB) of thyroid nodules. MicroRNA profiles will be determined and evaluated for their utility in pre-operative diagnosis, in particular to distinguish benign from malignant throid neoplasms. Post-surgical fresh-frozen thyroid cancer tissue will be assessed for somatic mutations, mRNA, and microRNA expression patterns. FFPE tissue will be used to obtain H&E and unstained slides to specific biomarker results using immunohistochemistry.
Pilot 99mTechnetium-MIBI Single Photon Emission Computed Tomography - Computed Tomography (SPECT-CT)...
Papillary Thyroid CancerThe purpose of this trial is to see if the 99mTechnetium-MIBI SPECT-CT can be a tool for preoperative evaluation of cervical node metastasis in papillary thyroid cancer.
Association Between Hepatitis C Virus Infection and Hematologic and Thyroid Cancers
Hepatitis C VirusThis study will investigate the possible relationship between infection with hepatitis C virus (HCV) and the development of certain hematologic cancers (Non-Hodgkin's lymphoma, Hodgkin's lymphoma, chronic lymphocytic leukemia, multiple myeloma) and thyroid cancer. HCV causes chronic hepatitis, cirrhosis, and liver cancer. It is transmitted primarily through injection drug use and transfusion of infected blood. Studies have shown that HCV may also be linked to hematologic cancers and thyroid cancer. This retrospective study will examine medical records from veterans with and without HCV infection who previously received treatment in the Veterans Administration medical system. Data collected on each subject will include the subject's race, sex, age and era of military service, presence of liver disease or thyroiditis at their baseline clinic visit, number of inpatient visits in the past 5 years and outpatient visits in the past year, and the presence of various specified cancers. The prevalence of cancer and other conditions among HCV-infected subjects and non-HCV infected subjects at baseline and the subsequent development of the cancers of interest in these two groups will be compared and analyzed for a possible causal relationship.
