Filter by:The purpose of this study is to find out whether a drug called PDR001, combined with either trametinib or dabrafenib, is a safe and effective treatment for thyroid cancer.
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.
Indocyanine green (ICG) is a water-soluble organic dye that is cleared totally through the hepatobiliary system. It has a half-life of 3-4 mins, which allows repeated applications. Near-infrared (NIR) fluorescence imaging with indocyanine green (ICG) imaging has been recently introduced, and has been suggested as a useful tool for the identification and preservation of the parathyroid glands (PGs) during total thyroidectomy (TT). ICG can also be used for sentinel lymph node (SLN) biopsy to predict the micrometastases in central lymph nodes (CLN) in thyroid carcinoma, and central lymph node dissection can reduce local recurrence.
In the last decades, thyroid cancer incidence has continuously increased all over the world, almost exclusively due to a sharp rise in the incidence of the papillary histologic subtype, which has the highest incidence of multifocality. Furthermore, Black Sea and Eastern European regions are both endemic and known to have been under the influence of Chernobyl nuclear explosion. Although overscreening might have a role in certain parts of the world, the predictors of malignancy such as family history, genetical disorders, previous radiation exposure, low iodine intake, diabetes and obesity, should also be taken into consideration in determining the extent of surgery.
In the present study, the severity of recurrent laryngeal nerve injury (RLNI) and hypocalcemia (H) will be followed-up and the probable interrelation between them will be proposed considering the clinical situation of patients, e.g. improvement in hypocalcemia also make a positive effect on voice? (any objective sign? Ca? PTH?), return of voice is parallel with the improvement in hypocalcemia? Postoperative calcium (Ca), parathyroid hormone (PTH), regular vocal cord evaluations by ear-nose-throat (ENT) exams, deterioration-stability-improvement of clinical symptoms regarding both Ca metabolism and vocal cord function will be noted at regular intervals (postoperative day 1-3-first, weekly control/first month, monthly/first 6-month, 3-monthly/6-12 months) at outpatient controls. Serum Ca, PTH, ENT evaluation of vocal cords-noted.
Primary objective: The 3-years disease-free survival was compared between low-dose group (30 mCi) and high-dose group (100 mCi). Secondary objective: The successful remnant ablation, efficacy, 3-year progression-free survival and safety were compared between low-dose group (30 mCi) and high-dose group (100 mCi). Research Hypothesis：The 3-year disease-free survival of low-dose group (30mci) may not be lower than that of high-dose group (100 mci) in intermediate-risk thyroid papillary carcinoma patients with no structural or functional lesions and stimulated thyroglobulin(ps-Tg)1-20ng/ml. Study design：Single-center, randomized, double-blinded Sample size：254 patients Follow-up：The measurement of serum thyroid function, thyroglobulin/ anti-thyroglobulin antibody(Tg/TgAb) and neck ultrasonography were performed every 3-12 months during the 3 years according to patients' condition, and computerized tomography(CT) scan, positron emission tomography/computed tomography(PET/CT) and diagnostic whole-body 131I scan were added if necessary. Intervention：Randomly allocated into two groups to receive either 30 mCi (low-dose group) or 100 mCi (high-dose group ) radioiodine for post-thyroidectomy ablation therapy. Evaluation index：Primary evaluation index: The 3-year disease-free survival. Secondary evaluation index: Successful remnant ablation, efficacy, the 3-year progression-free survival and safety.
study assigned into three groups, Group I was the control group operated by total thyroidectomy and retrospectively followed, where the other two groups Operated by Total thyroidectomy and central neck dissection. Recurrence Free Survival (RFS) was the main issue of the study and calculated as the time from date of surgery to date of relapse or the most recent follow-up contact that patient was known as relapse-free, Study exclusively studied the outcome and advantage of central neck dissection
The study aimed to compare the efficacy and safety of papillary thyroid microcarcinoma (PTMC) treated with microwave ablation(MWA) and surgery resection (SR), and to explore the tumor characteristics suitable for each treatment methods (such as with and without capsular invasion). The investigators organized 18 hospitals to participate in this multicenter study. Patients meeting following indications will be included in this study: 1. Biopsy pathology proved PTMC, but not high-risk subtype; 2. solitary mPTC, without US-detected gross extrathyroid extension; 3. no evidence of metastasis; 4 willing to participate in this study and perform regular follow-up. Patients themselves decide to receive MWA or SR for mPTC after medical consultation. Baseline characteristic including age, gender, thyroid function et al. will be collected. The treatment protocols of MWA and SR were according to the Chinese and international guidelines. The primary outcomes were the disease progression, including local tumor recurrence, lymph node metastasis, and distant metastasis. The secondary outcomes include thyroid function, complication rate, blood loss et al. Investigators will follow up enrolled patients and collect and upload data according to the trial. Treatment outcomes of tumor with and without US-detected capsular invasion was analyzes as subgroups.
Investigators intend to evaluate the efficiency of Radiofrequency ablation (RFA) therapy to treat papillary thyroid carcinoma.
