Active clinical trials for "Thyroid Neoplasms"

The goal of this retrospective study is to evaluate in patients with HCC and FTC who underwent lobectomy. The main questions it aims to answer are: The necessity of completion thyroidectomy based on the clinicopathological characteristics Prognosis Participants underwent thyroid lobectomy Researchers compared HCC and FTC groups to see the prognosis after lobectomy.

This research study is performed to compare the accuracy of two methods of lymph node evaluation: research method versus standard method. Standard method is what is usually performed as standard of care where the radiologist evaluates the images overall and decides whether each node seen should or should not be biopsied. In the research method, a second radiologist will evaluate the ultrasound images of the lymph nodes separately, and use a small specific checklist of ultrasound appearance to determine whether each node should or should not be biopsied. Results of both the standard and research method will be used to decide which node(s), if any should be biopsied. Neck ultrasound examination, lymph node evaluation by standard method and subsequent lymph node biopsy are part of the standard clinical care. It is less likely but possible that the research method may identify additional lymph nodes for biopsy to check if that lymph node contains thyroid cancer.

The investigation of thyroid nodules is limited by the fact that up to 49% of the fine needle aspirations (FNA) performed are of "indeterminate cytological signification". Moreover, no fully reliable molecular marker for thyroid cancer have been described. The goal of this project is to study the expression of a specific kind of protein convertase in benign and in malignant thyroid nodules to determine its potential as a biomarker.

This study is being done to understand the decision-making process regarding management choice in low-risk papillary thyroid cancer.

During surgery, a fine needle puncture was proceeded when suspicious nodes was found by clinician. Repeat the punction for 2-3 times from different orientation and then, Diff-quik staining or PTH immunochromatographic assay were proceeded for lymph node or parathyroid glands identification. Post-operative pathology outcome was considered as golden standard.

Correlation analysis between estimated renal function and biological half life of 131-I during radioiodine treatment of patients with differentiated thyroid cancer.

Aberration of glycosylation is a hallmark of cancer cells, and plays an important role in oncogenesis and cancer progression, including metastasis. One of the markers of aberrant glycosylation (O-linked) is the binding of the lectin Helix pomatia agglutinin (HPA), which has been demonstrated in a wide range of human cancers, especially in tumours with a more aggressive phenotype. Data on the role of HPA within follicular neoplasms of the thyroid gland are currently lacking, therefore we sought to investigate possible changes in cell surface glycosylation associated with this type of neoplasms.

This project will examine the role of the whole body, PET and SPECT imaging before, during and after radionuclide treatment for 177Lu-Dotatate therapy, whole body and SPECT imaging for 131-I for thyroid cancer therapy, and whole-body imaging for 131I for hyperthyroidism therapy. Whole-body and SPECT images will be linked to personal dosimeter readings to determine whether Current radiation protection advice for patients receiving radionuclide treatment is appropriate. Radiopharmaceutical retention and/or SUV change in patients undergoing repeated radionuclide treatments. Data combined from early (quantitative imaging) and late (whole-body dose rate measurements) could support individual treatment planning for patients undergoing repeated cycles of molecular therapy.

Patients with hyperthyroidism and/or goiter are evaluated with blood samples and scintiscan before they are treated with radioiodine for their thyroid disease. Because the investigators do not get a histologically/final diagnosis the investigators want to make sure, that the patients treated do not have a thyroid cancer when treated. The investigators have found that thyroid cancer is not overlooked.

Patients over the age of 18 with thyroid nodules scheduled for surgery will undergo EIS scan. Each node will be scanned and graded form 1-5 (1=benign, 5=malignant). Results will be compared with final histopathology.
