Percentage of BRAFV600E Alleles and Outcome in Thyroid Carcinoma
Papillary Thyroid CancerBRAFV600E is the most frequent oncogene in Papillary thyroid carcinoma (PTC). It correlates with greater extension, lymph node metastasis, and advanced stage. However, the prognostic value of BRAFV600Eis weak and the search of this mutation is not recommended in clinical management of thyroid cancer. PTC are characterized by intratumor heterogeneity with wild-type and BRAFV600E tumoral cells. In a previous study, the BRAFV600E/BRAFwild-type ratio correlated with patient age, tumor volume, lymph node metastasis and with worst disease outcome. While the existence of intratumor heterogeneity in PTC is supported by many evidences, its extension, biological significance and clinical utility is questioned and must be further investigated. Primary endpoint of the study is to determine the relationship between the percentage of BRAFV600E alleles and outcome in PTC patients. Secondary endpoints are to determine the mean and median BRAFV600E/BRAFwild-type allele ratio in heterogeneous tumors; determine the relationship between the percentage of BRAFV600E alleles and clinicopathological features. The study protocol entails the assessment by digital-droplet PCR the BRAFV600E/BRAFwild-type allele ratio in a series of PTC and its correlation with clinicopathology features and outcome.
Comparative Study in Oral, Breast Approach and Open Thyroidectomy
Thyroid NeoplasmsPurpose: Total endoscopic thyroidectomy including oral approach and breast approach has excellent cosmetic and several functional results. Many patients, especially women, undergoing thyroid surgery are concerned about the postoperative cosmetic appearance of the neck. The procedure of total endoscopic thyroidectomy by breast approach only left three incisions, while by oral approach did not leave any incisions in the body surface, which is scarless in the neck, involved with a higher cosmetic result. However, the long-term property evaluation of total endoscopic thyroidectomy was not confirmed. The purpose of our study was to evaluate the surgical results of total endoscopic thyroidectomy (transoral approach and breast approach) versus conventional open thyroidectomy.
Detection of Benign and Malignant Thyroid and Breast Tumors by Fourier Transform Infrared Spectrometry...
Thyroid TumorBreast TumorThe purpose of this stage of study is to establish discriminant among healthy tissue, benign and malignant thyroid and breast tumors by fourier transform infrared spectrometry variables.
Evaluation of a New CZT System
Parathyroid AdenomaThyroid AdenomaThe purpose of the study is to check if the new CZT system has an advantage in detection of small osseous processes, thyroid adenomas, parathyroid adenomas and detection of sentinel node, in comparison with the techniques in use. Participants: 100 subjects male and female that come to the institute of nuclear medicine for routine screening examinations. The CZT screening takes 10 minutes and does not require any extra intervention to the routine screening.
Relationship Between Computer and Cancer
Thyroid CancerThyroid Cancer is one of the most common malignant carcinomas. The incidence of thyroid cancer has risen in the past years. The recrudesce rate is highly raised. Computer is widely used by people nowadays, is it a predisposing factor to the highly raised recrudesce rate? This research observed two random assigned groups, in which the patients were diagnosed by pathologic results. One group were strictly prohibit with using computer, the other were not told. Finally collect the recrudesce rate of each group, analyze the data by statistic software.
Initial Management in Patients With Differentiated Thyroid Cancer in the Real World in China
Differentiated Thyroid CancerTo find out the gap between real-world clinical practice and guideline recommendations in initial management of DTC patients To observe the characteristics of patients who achieved and did not achieve TSH target value after one year follow-up To assess response to initial therapy in patients who undergo total or near-total thyroidectomy and RAI remnant ablation after one year follow-up (according to an modified dynamic risk stratification system) To observe the recurrence status after one year follow-up
MOLecular Characterization and Treatment of THYroid Carcinoma on Struma Ovarii
Ovarian CancerThyroid carcinoma on struma ovarii (TCSO) is a rare ovarian tumor, derivate from monodermic teratomas. It represents about 0.01% of overall ovarian tumours, and 5 to 10% of struma ovarii. The diagnosis is histologic and retrospective after pelvic surgery. Because of its rarity, the treatment of TCSO is not consensual and should be validated in multidisciplinary team involved in rare ovarian carcinoma. TCSO should be taken care of as a thyroid carcinoma, in case of relapse, with systemic treatment, as tyrosine kinase inhibitor (TKI), without any clinical trial proving this benefit. Indeed, molecular profiles and genomic expression is unknown, because of studies with few patients (less than 10) contrary to thyroid carcinomas with the TCGA genomic classification. The study purposes are the outcome of the patients after the first treatment and the comparison of the genomic profil in next generation sequencing (NGS) with TCGA thyroid carcinoma profile. Thus, the treatment could be tailored, confirming the same therapy as in thyroid carcinoma.
An Easy Sonographic Scoring System for Predicting Malignant Thyroid Nodules
Thyroid CancerThe purpose of the investigators study is to retrospectively evaluate the predictors of malignant thyroid nodules and established an useful scoring system based on sonographic findings and demographic data.
Relationship of Metabolic Syndrome and Its Components With Thyroid Cancer
Thyroid CancerThe purpose of this study is to investigate the association between metabolic syndrome (MS), body mass index (BMI), hyperglycemia, dyslipidemia, hypertension and thyroid cancer. Screen for the risk factors that affect the incidence of thyroid cancer.
Long Non Coding RNA HOTAIR and Midkine as Biomarkers in Thyroid Cancer
Thyroid CancerThyroid cancer is the most prevalent endocrine malignancy.Papillary thyroid carcinomas and follicular thyroid carcinomas account for 95% of all thyroid cancer cases. They are clinically classified as well-differentiated thyroid carcinomas due to their biological behavior resembling normal follicular cells and good responsiveness to surgery and radioiodine therapy . However, they are usually curable when discovered at early stages, but survival rates may be reduced from 100% in stages I and II to 50% at stage IV So,early detection is the key for successful treatment and reduction of mortality. pathological analysis by fine-needle aspiration biopsies has some limitations including difficulty in sampling small tumors, inconclusive diagnosis in up to 35% of patients and bleeding. Thus, biomarkers for diagnosis are needed.
