Active clinical trials for "Thyroid Neoplasms"

The robot-assisted surgery for benign and malignant thyroid tumors was widely developed in Asia and begins to spread in Western countries. The main advantage of the technique is to avoid a scar in the neck by placing it either in the axilla or at the hairline behind the ear to improve esthetic consequences and body image. It is not surgery minimally invasive but rather a way of remote access surgery. Data from the literature including cohort studies and meta-analyzes attest the security of the procedure in comparison with classic thyroid surgery (which remains the "gold standard"). However there is few data on the effectiveness of the technique in terms of the completeness of the surgery, according to the routine standard criteria used in endocrinology and endocrine cancer, and no French medico-economic study has been performed.

The aims of this trial are to evaluate the efficacy and tolerability of pemetrexed + paclitaxel in patients with recurrent/advanced follicular, papillary or anaplastic thyroid cancer.

RATIONALE: Everolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor. PURPOSE: This phase II trial is studying how well everolimus works in treating patients with progressive or recurrent, unresectable, or metastatic thyroid cancer.

This research study is to compare the radiopharmacokinetics of I-124 to the radiopharmacokinetics of I-131 in patients who have well-differentiated thyroid cancer after recombinant human thyroid-stimulating hormone (rhTSH) injection. I-131 is routinely used for imaging and dosimetry for patients with well-differentiated thyroid cancer. In this study, I-124 is administered orally in capsular form, and the radiopharmacokinetics of I-124 is compared with I-131. I-124 is another isotope of iodine, which is cyclotron-produced. I-124 has multiple advantages: Ideal Half-Life (4.2 days) for delayed imaging. High resolution tomographic imaging. Feasibility of quantitating lesion uptake. Potential of dosimetry for the planning of radioiodine therapy. Voluntary patients will have I-124 dosimetry performed in addition to the I-131 dosimetry, which is planned as part of routine clinical care. I-124 dosimetry is composed of four parts: (1) two extra doses of injections of rhTSH, (2) the administration of I-124, (3) PET imaging, and (4) drawing blood samples. Patients will receive two additional injections of rhTSH. This is similar to the procedure for I-131 dosimetry. Second, they will receive I-124. I-124 is similar to I-131 except I-124 decays in a different way to emit a positron so that the PET scanner can be used for imaging. I-124 is given in the form of one or several capsules, which are taken by mouth. This is also similar to I-131. Third, PET/CT imaging is done for approximately 30 minutes to one hour on five consecutive days. Radiation from PET/CT scan is far less than what they receive from a diagnostic CT scan. For the fourth part, a technologist will draw about 5 cc from the forearm on each of the five consecutive days. This is also similar to I-131. Initially, all patients will be randomized to one of two study groups. The first group will have the I-131 dosimetry performed first followed by the I-124 dosimetry, and the second group will have the I-124 dosimetry performed first followed by the I-131 dosimetry. The risk of this study is considered very low, and the potential benefits to the patient are considered very high.

RATIONALE: Radiofrequency ablation uses a high-frequency, electric current to kill tumor cells. Ultrasound-guided radiofrequency ablation may be effective treatment for thyroid cancer. PURPOSE: This phase I trial is studying the side effects of radiofrequency ablation in treating patients who are undergoing surgery for thyroid cancer.

The researchers investigated the rate of biochemical remission in patients without radioactive iodine therapy compared to patients with low dose radioactive iodine treatment in differentiated thyroid cancer patients who underwent total thyroidectomy.

The purpose of the study is to evaluate the concordance between the 18F-PET/CT under thyrotropin stimulation and the diffusion-weighted Magnetic Resonance Imaging, in the detection of residual mass in 40 patients with partial response or relapsed differentiated thyroid carcinoma.

Objective to compare the advantages and disadvantages of robotic and conventional endoscopic thyroidectomy for thyroid cancer.

The impact of the COVID-19 pandemic has heavily influenced routine medical care. In the first months of the pandemic, healthcare authorities restricted medical care to emergency procedures, postponing elective surgical activity. Conversely, screening programmes and planned examinations have been temporarily suspended or delayed. Gradually, elective surgery and clinical activities have resumed, thanks to the weakening of the pandemic, to a better organization of the healthcare systems and to the diffusion of COVID-19 vaccines. In the present study, we aim to evaluate the impact of the COVID-19 pandemic on surgery for thyroid carcinoma. Particularly, we aim to investigate whether the delay in operations, screening programmes, and planned examinations for patients under follow-up after thyroid surgery have led to an increased number of aggressive tumours. To evaluate this aspect, we aim to compare the patients who had undergone thyroidectomy for thyroid cancer before the COVID-19 pandemic (from February 2019 to February 2020), during the first phase of the pandemic (from March 2020 to September 2020), and after the first phase of the COVID-19 pandemic (from October 2020 to October 2021).

The purpose of this study is to determine whether BRAF V600E mutation in our patients with papillary thyroid cancer has an association with poor prognosis.
