Filter by:Background After diagnosing well-differentiated thyroid cancer (WDTC), careful assessment of the risk for disease-specific recurrence is essential for deciding between partial (low risk) and completion (high risk) thyroidectomies. Patients' preoperatively determined risk levels are re-stratified according to surgical and final histopathological findings. The American Thyroid Association 2015 guidelines suggest that patients with WDTC between 1-4 cm in size and without suspicious features may be suitable candidates for partial thyroidectomy. The incidence and clinical implications of high-risk features discovered postoperatively in patients with preoperatively determined low-risk WDTC have not been previously reported. Methods All thyroidectomies performed between 2006-2018 in the Tel Aviv Sourasky Medical Center were included. Pre- and postoperative risk stratifications were performed, and the rate of completion thyroidectomy was determined. Patients with 1-4 cm WDTC without evidence of positive cervical lymph nodes, invasion to adjacent structures, or high-risk cytology were considered at low risk for disease-specific recurrence and therefore suitable for lobectomy.
The purpose of this study is to develop a new drug treatment to reverse tumor resistance to radioiodine in BRAF mutant tumors so that radioiodine can be given to shrink tumors. This study is also being done to find out the highest doses of copanlisib and vemurafenib that, when given in combination, do not cause serious side effects, and whether the study treatment will make radioiodine therapy work better in patients with BRAF-mutant thyroid cancers.
Almost 50 % of papillary thyroid cancer (PTC) patients have central lymph node metastases (CLNM), which are associated with a high risk of persistent or recurrent disease. However, the practice of performing a prophylactic central lymph node dissection (PCLND) routinely remains controversial. The proponents argue that without a PCLND, PTC patients with positive lymph nodes have an increased risk of local recurrence, and postponed node dissection leads to with 5-6 fold higher risk of morbidity. If performed, PCLND in clinical node negative patients increases staging to pN1 in more than 50% of the cases without increasing survival. The complication rate in PCLND is lower when compared to a technically challenging re-exploration in recurrent disease, with reported incidences of 0.6% and 7.3-20%, respectively. Opponents of routine PCLND point out the lack of randomized clinical trials and object to treatment-induced hypo-parathyroidism and recurrent nerve damage for the N0 patients. Currently, no diagnostic tool is available which reliably identifies these patient categories. Therefore, there is a clear need for novel diagnostic imaging modalities that overcome this issue. Molecular Fluorescence Guided Surgery (MFGS) is potentially such a diagnostic tool. The administration of NIR fluorescent tracers can increase detection accuracy of cancer and nodal metastatic tissue using macroscopic MFGS. Therefore, we aimed to identify a GMP-produced near infrared (NIR) tracer that potentially has a high target-to-background ratio in PTC compared to normal thyroid tissue. Tyrosine-protein kinase Met (c-Met) is significantly upregulated at the protein level in PTC compared to normal thyroid tissue. The investigators therefore hypothesize that the GMP-produced NIR-fluorescent tracer EMI-137 (targeting c-Met, peak emission at 675 nm range) might be useful for intraoperative imaging of PTC and nodal metastases. The investigators' aim is to investigate if the administration of EMI-137 is a feasible approach to detect PTC nodal metastases. Ultimately, this method might be useful to improve patient selection for CLND. Eventually, we might also be able to visualize multifocality, more selective lateral neck dissections and asses residual tissue after thyroidectomy. Ultimately, all of these strategies may reduce overtreatment, morbidity, and costs while maintaining the same or better effectiveness with a lower recurrence rate and improved quality of life.
This study is being done to understand the decision-making process regarding management choice in low-risk papillary thyroid cancer.
This is a Phase 1/2, open-label, first-in-human (FIH) study designed to evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), and preliminary antineoplastic activity of pralsetinib (BLU-667) administered orally in participants with medullary thyroid cancer (MTC), RET-altered NSCLC and other RET-altered solid tumors.
This phase II trial studies how well pembrolizumab and lenvatinib work in treating patients with differentiated thyroid cancer that has spread to other places in the body or has come back and cannot be removed by surgery. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.
The purpose of this study is to compare the therapeutic effects between the axillary bilateral-breast approach (ABBA) and bilateral axillo-breast approach (BABA) for robotic thyroidectomy.To explore the efficacy, safety, cosmetic results and clinical value by the two approaches.
The aim of this study is to investigate the efficacy and safety of prophylactic central lymph node dissection in papillary thyroid carcinoma.
Magnetic resonance imaging (MRI) is a diagnostic technique that takes pictures of organs of the body. It uses magnetic fields and radio waves that cannot be felt. Perfusion MRI uses faster imaging. It also includes a contrast material that is given by vein. This makes specific organs, blood vessels, or tumors easier to see. Diffusion MRI lets us measure the motion of water in the tumor. Perfusion and diffusion MRI give extra information which is not available with the regular MRI. A regular MRI only shows pictures of the tumor. Thyroid MRI scans are not part of the current standard of care. The purpose of this study is to see if new MRI methods can give us more information about the tumor.
This phase II trial studies how well thyroid gland removal with or without central lymph node dissection works in treating patients with thyroid cancer or suspected thyroid cancer that has not spread to the lymph nodes (randomized into Arms I and II). Arms I and II are compared to a standard of care (SOC) Arm III to enable comparison of quality of life among various surgical treatments. Currently, the standard treatment for thyroid cancer is total thyroidectomy, or complete removal of the thyroid. The lymph nodes in the central part of the neck may also be surgically removed, called central lymph node dissection. Prophylactic removal of the lymph nodes may increase the risk of life-threatening complications, and may reduce post-surgery quality of life. It may also prevent the cancer from returning and reduce the need for additional surgery. It is not yet known whether recurrence rates and complication levels are lower after thyroid gland removal alone or with central lymph node dissection.
