Active clinical trials for "Thyroid Neoplasms"

Endoscopic thyroidectomy developed rapidly in recent years, and the most popular surgical approach was endoscopic thyroidectomy by bilateral areola approach, but some operative steps was required optimization. One of the most annoying problem was the smog blurring endoscopic lens during surgery. The researcher summarized a set of convenient foot-control exhaust method and carried out this prospective study.

This study is being done to help researchers learn more about and successfully diagnose cancer using blood samples and tissue samples from surgeries in patients with suspicious thyroid nodules or thyroid cancer. Diagnosing cancer in this way, as opposed to biopsies, may be less invasive to the patient. Analyzing blood and tissues samples may also help researchers to differentiate non-cancerous tumors from thyroid cancer and detect high-risk mutations to guide treatment.

Harmonic scalpel is a new surgical instrument. Its use has been recommended in patients submitted to total thyroidectomy. Few randomized controlled trials has been published. However they had small sample sizes, used intermediate outcomes and included different surgical procedures. Our objective is to asses the use of Harmonic scalpel in patients submitted to total thyroidectomy using surgical complications, operative time, drainage volume, postoperative pain, length of stay and costs as outcomes. Our hypothesis is that Harmonic scalpel decreases operative time,drainage volume, postoperative pain, length of stay and costs without increasing surgical complications

Immunohistochemical detection of the BRAF-V600E mutation on pre-operative fine needle aspiration biopsy (FNAB) from patients suspected for papillary thyroid carcinoma, using the mutation specific antibody VE1.

In accordance with the current guidelines,papillary thyroid microcarcinoma such as turmo invasive nerve or trachea, requires total thyroidectomy for follow-up iodine-131 treatment.In the course of clinical work, if the patient can achieve R0 resection, most of the patients do not need iodine-131 treatment,Therefore, there is no need to continue total thyroidectomy.To evaluate the practicable, thoroughness and Clinical value of bilateral central compartment dissection while preserve contrary thyroid glands.

In this study, patients diagnosed with a pathology-proven malignancy of the head and neck will receive a routine clinical activity of 18F-FDG ((18)F-luorodeoxyglucose) before undergoing standard of care surgical resection of the malignancy. Following the resection, the 18F-FDG-infused malignancy will be investigated utilizing a novel high-resolution Positron Emission Tomography (PET) and Computed Tomography (CT) scan. Slicing of the malignancy will be followed by additional PET/CT-scanning and autoradiography of the sliced specimen. The results found during image analysis will be compared to the results of the gold standard of histopathology. As this is no approved way of assessing the tumour's margin, the conclusion of the scan will not be used as a method for changing the patients' treatment.

Determine the diagnostic value of 18F-PSMA-11 in patients with iodine refractory thyroid cancer.

Detection of lymph nodes starting to be involved by cancer spreading from the thyroid gland during operation is useful. It saves the patient from having a second operation to remove these nodes later on when they become obvious. The problem is that there are many lymph nodes around the gland. The theory is that only one node will get the first spill of the tumour cells. In this study the investigators are trying to use an inert colored material to inject into the tumour. This should run in the same path as the tumour cells and should therefore stain the one lymph node that will be affected first should the tumour spread. The stained lymph node is excised and examined instantaneously for tumour affection. If it is found to be affected by the tumour, then the operation is extended to include removal of all its fellow lymph nodes. If it is found to be free from the tumour, then this patient does not have tumour spread.

The main purpose of this study is to see how well FDG-PET scans can determine the malignancy of thyroid nodules that have already been tested (and come back positive) by fine needle aspiration.

While thyroid cancer is generally associated with a favourable prognosis, there is a discrepancy with how important if not traumatic its impact can be on patients. Quality of life (QoL) decreases in the year following a thyroid cancer diagnosis, constituting an optimal period for a preventive intervention. The goal of this study is to evaluate the impact of offering an interdisciplinary team-based care approach for newly diagnosed thyroid cancer patients, including a dedicated nurse who will provide important psychoeducational elements identified in previous focus group studies of thyroid cancer patients, i.e., information on: the physical illness; the emotional impact of being newly diagnosed with thyroid cancer; surgery and its' short- and long-term consequences; radioactive iodine treatments and its associated safety precautions, nutrition and dietary considerations; and how the cancer diagnosis can be an opportunity to make important lifestyle changes and establish new life-priorities.
