Active clinical trials for "Thyroid Neoplasms"

The primary objective of the study is to assess the anti-tumor activity of REVLIMID® (lenalidomide), administered as a single agent, in patients with distantly metastatic thyroid carcinomas which are unresponsive to systemic radioiodine, in terms of tumor response and response duration.

This proposal is designed as a pilot study for the use of laser ablation for local control of symptomatic (e.g compressive) benign thyroid masses in 20 patients.

RATIONALE: Radiolabeled monoclonal antibodies can locate tumor cells and deliver tumor-killing substances to them without harming normal cells. Chemotherapy uses different ways to stop tumor cells from dividing so they stop growing or die. Peripheral stem cell transplantation may be able to replace immune cells that were destroyed by radioimmunotherapy or chemotherapy used to kill tumor cells. PURPOSE: Phase I/II trial to study the effectiveness of radioimmunotherapy with or without doxorubicin plus peripheral stem cell transplantation in treating patients who have thyroid cancer.

Thyroid cancer is typically treated with surgery, radiation or a combination of both. Following surgical removal of thyroid tissue patients receive thyroid hormone replacement medication. In addition patients undergo tests to determine the status of the disease. One of the tests conducted is a whole body scan using radioactive iodine to detect and locate any remaining cancerous thyroid tissue. Thyroid tissue uses iodine to make thyroid hormones (T3 and T4). In order for a radioiodine scan to work, cancerous thyroid tissue must be "hungry" for iodine. Thyroid stimulating hormone (TSH) produced in the pituitary gland is responsible for making thyroid tissue "hungry" for iodine. Once thyroid tissue absorbs the radioactive iodine it will be clearly visible on the scan and can be located for removal. However, thyroid hormone replacement medication tends to lower the activity of the pituitary gland and the amount of naturally produced TSH. So it is necessary to stop thyroid hormone replacement to increase TSH. A problem arises when there is a lack of thyroid hormone replacement causing patients to experience hypothyroidism. This condition is associated with unpleasant physical and emotional symptoms. TSH has been created in a laboratory and called Thyrogen. It is basically the same as the TSH produced in the human pituitary gland. However, Thyrogen increases the level of TSH in the body without having to stop thyroid replacement medication. Therefore patients will not experience hypothyroidism while preparing for a radioactive iodine scan. The objective of this study is to compare the activity of radioiodine (131I) in patients taking Thyrogen with normal thyroid activity versus patients with hypothyroid activity after thyroid replacement medication is withdrawn. In addition the study will provide information on how radioactive iodine is eliminated from the body. The study will help researchers understand how to give Thyrogen and radioiodine for purposes of scanning and therapeutic ablation (the destruction of function) of cancerous thyroid tissue. The study will accept patients with non-medullary thyroid cancer who are preparing for ablation therapy. The patients will be placed in one of two groups. Group one will receive Thyrogen in 2 doses 24 hours apart. Group two will receive Thyrogen in 3 doses 72 hours apart. The patients will undergo two 131I whole body scans: one after Thyrogen while taking thyroid hormone suppressive and the second after withdrawal from thyroid hormone. 131I ablative therapy will be given under hypothyroid conditions at the completion of the study.

Clinical studies, with a distinct emphasis on medullary thyroid cancer, play a pivotal role in evaluating the safety and effectiveness of novel treatments for this condition. These trials serve as essential tools to determine whether new medications surpass conventional therapies, providing substantial evidence to endorse their broader adoption. The primary objective is to meticulously examine trial completion rates and voluntary withdrawals within this specific patient group. By actively participating in this observational study plays a critical role in pushing medical knowledge forward and advancing care for individuals suffering from the medullary thyroid cancer.

This pilot clinical trial studies how well Gallium-68 prostate specific membrane antigen positron emission tomography (PET) work in diagnosing patients with thyroid cancer. Diagnostic procedures, such as 68Ga-PSMA PET, may more accurately diagnose thyroid cancer and find out how far the disease has spread.

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.

We aim to study the effect of local anesthetic when used in conjunction with general anesthesia during thyroidectomy or parathyroidectomy. We hypothesize there is equivalent pain control between bilateral superficial cervical plexus block and local wound infiltration when used in conjunction with a general anesthetic.

The study is a phase I multicentre randomized, open, parallel-arm clinical trial conducted to investigate the IMP, namely 111In-CP04. The study consists of preclinical (to establish a clinically useful formulation for the radiolabelled peptide CP04), and a clinical step. The main objective of the clinical part of the project is to establish the safety of i.v. administration of a high peptide amount and to assess the tracer biodistribution and dosimetry in MTC and normal tissues and to determine critical organs as well as the evaluation of the potential of CCK2 receptor scintigraphy to detect cancer lesions for both low (10ug) and high (50ug) peptide amount and the decrease of kidney dose after co-administration of gelofusine /gelaspan as a nephroprotective agent. To achieve this, the following study design has been accepted: the first 4 patients will receive 2 peptide amount of CP04: low peptide amount (for diagnostic purpose) and high peptide amount (for therapeutic purpose) of CP04. If no SAE is present, the remaining pts will be randomized for 2 arms: high peptide amount of 111In-CP04 with and without gelofusine/gelaspan infusion. It is expected that CCK-2/gastrin receptor imaging will become a valid diagnostic method for a specific non-invasive staging and follow-up of patients with MTC, and treatment of recurrent and disseminated disease will be more efficient with minimized nephro- and myelotoxicity (if 111In labelled).

This phase II trial studies how well pembrolizumab, chemotherapy, and radiation therapy work with or without surgery in treating patients with anaplastic thyroid cancer. Monoclonal antibodies, such as pembrolizumab, may interfere with the ability of tumor cells to grow and spread. Drugs used in chemotherapy, such as docetaxel and doxorubicin hydrochloride, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high-energy x-rays to kill tumor cells and shrink tumors. Giving pembrolizumab, chemotherapy, and radiation therapy with or without surgery may kill more tumor cells and work better in treating patients with anaplastic thyroid cancer.
