Filter by:Background: Most patients with thyroid cancer have a long life expectancy, and it has been assumed among health professionals that therefore the quality of life (QOL) is good. Some European studies have shown that the quality of life among thyroid cancers is worse than the general population, and almost as low as other cancer diagnoses, with a worse prognosis and a more burdening treatment. Aim: To examine prospectively the quality of life in participants undergoing diagnostic thyroid surgery and participants undergoing surgery for certain thyroid cancer. By examining both groups we wish to find answers if quality of life is affected, and if so - mostly affected by the diagnosis or the surgery itself. Methods: Participants enroll the study after informed consent, and quality of life will be assessed using quality of life questionnaires EORTC QLQ C30, EORTC THY 47 and EORTC FA12 before surgery, and 6 and 12 months after surgery. This study will form two main groups of participants; with and without thyroid cancer.
This is an observational study of voice outcomes in participants following thyroidectomy or another head and neck surgery that does not involve risk to the larynx other than risks incurred due to intubation alone. These comparative (non-thyroidectomy) surgeries would not be expected to interfere with the primary nerves involved with voice production, so they would help to better understand the effect of intubation alone on voice outcomes.
Participants will have been diagnosed with advanced progressive thyroid cancer and are about to start treatment with a tyrosine kinase inhibitor (TKI). The purpose of this study is to evaluate the efficacy and tolerability of tyrosine kinase inhibitor therapy (Lenvatinib or Sorafenib for differentiated thyroid cancer [which includes papillary thyroid cancer, follicular thyroid cancer, and poorly differentiated thyroid cancer]; and Cabozantinib or Vandetanib for medullary thyroid cancer) through adaptive (intermittent) versus conventional (continuous) regimen.
The prevalence of thyroid cancer has increased in recent decades. Patients with thyroid cancer need to choose between Thyrogen® injection and Eltroxin® withdrawal before radioiodine therapy or scan. This is a prospective, observational study, aiming to observe the difference of metabolic profiles between patients choose Thyrogen® injection and Eltroxin® withdrawal.
Patients in our department endoscopic thyroidectomy were randomly divided into high position and low position established operating space group established operating space group. The thyroid size, patient BMI, operation time, and intraoperative blood loss were compared between the two groups.
Prospective randomized open phase III non-inferiority trial in cT1bT2N0 papillary thyroid carcinoma comparing: total thyroidectomy alone (experimental group) versus total thyroidectomy + Prophylactic Neck Dissection PND (reference group). Pre-registered patients will be randomized before surgery for tumors with class-6 cytology (Bethesda) or in the operating room after confirmation of malignancy by frozen section analysis for tumors with class-5 cytology.
This is an Expanded Access Program to make lenvatinib available to participants with radioiodine-refractory differentiated thyroid cancer in Brazil. Participants who have no other treatment options available, and who, in the opinion and clinical judgment of the treating physician, would benefit from treatment with lenvatinib will be enrolled. This is a multicenter, open-label program consisting of 2 phases: a 28-day pretreatment phase (including screening) and a treatment phase. Treatment will be provided as long as there is a clinical benefit based on tumor assessments performed according to the center's standard of care and the judgment of the participant's treating physician.
In recent years, the application of intraoperative recurrent laryngeal nerve monitoring in thyroid surgery has greatly reduced the complications of recurrent laryngeal nerve injury. The use of intraoperative neurological monitoring requires the reduction of the dose of neuromuscular blockade, which often leads to muscle tremors during the application of electrical energy, which affects the fine separation around the muscles. This study explored the effect of local application of lidocaine on reducing muscle tremor during surgery and its optimal dose.
The Collar Therapy Indicator (CoTI) (A device that is placed in collar around the neck resembling a turtle neck sweater collar with a wire and recording box) has been shown in a single small previously published experience to provide data regarding radioiodine exposure that correlates with conventional methods of measuring I-123 and I-131 uptakes after diagnostic dose administration and/or therapy for thyroid disorders. We hypothesize that the device's continuous measurement capability will permit more accurate estimates of radiation exposure to thyroid tissue than conventionally employed methods assessing fractional uptake at one or a few time points. It may also provide information about the extent of variability in the absorbed radiation dose among patients with thyroid cancer and hyperthyroidism. By providing more complete information about individual patient's exposures, it will facilitate more accurate estimation of the administered I-131 dose requirements for control of hyperthyroidism and thyroid remnant ablation while reducing the need for repeated visits to the clinic for dosimetry measurements. The aims of our project include the following: (1)To compare quantitative imaging-derived thyroid time activity curve to that obtained using the CoTI and to determine the extent to which there is variability in radiation dose predicted using conventional methods to that predicted from measurement of the full Time-Activity Curve (TAC).(2) Evaluate the uptake and clearance kinetics across the 5 patients in each category as proof of principle for a potential larger trial to investigate use of this device in optimizing the administered doses of radioactive iodine to achieve therapeutic goals while minimizing risks of comorbidities, such a post-radioiodine hypothyroidism in patients with Graves' disease.(3)Evaluate patient experience, convenience, and discomfort in using the CoTI device with a survey instrument.
