Active clinical trials for "Thyroid Cancer, Papillary"

We assess the effectiveness of percutaneous ethanol ablation for the treatment of thyroid cancer.

This study will evaluate the efficacy and safety of alectinib in participants with Anaplastic Lymphoma Kinase (ALK)-positive locally advanced or metastatic solid tumors other than lung cancer.

This phase II trial studies how well lenvatinib works when given together with standard of care iodine I-131 in treating patients with radioactive iodine-sensitive differentiated thyroid cancer. Lenvatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

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.

Papillary thyroid cancer (PTC) is the most common subtype of thyroid cancer. The most common site of PTC nodal metastases is the central neck, which has a reported rate of lymph node metastases as high as 50%~70%. Central neck dissection has important value to ensure accurate clinical staging and surgical planning. As a novel lymphatic tracer, carbon nanoparticles (CN) have been applied successfully in the detection of sentinel lymph nodes in breast and gastric cancers, while not been used as a lymphatic tracer for PTC. The goal of this study was to evaluate whether the use of CN facilitates the detection of lymph nodes, increases the number of metastatic lymph nodes removed, accurately reflects the metastatic condition of the central neck, and has the potential to protect the parathyroid glands.

Blood will be drawn 1 month before and 2 month after regular radioactive iodine treatment. Monocytes will be isolated. The three main outcomes are whole blood counts, cytokine production upon in vitro stimulation of monocytes and in vitro ROS production by monocytes. These results are compared between patients treated in adjuvant setting and patients treated for persistent structural disease, and between pre- and post-treatment status.

This open-label, multi-center study will evaluate the safety and efficacy of Vemurafenib (RO5185426) in participants with metastatic or unresectable papillary thyroid cancer (PTC) positive for the BRAF V600 mutation and resistant to radioactive iodine therapy. Participants will receive vemurafenib 960 milligrams (mg) orally twice daily until progressive disease or unacceptable toxicity occurs.

The purpose of this study is to determine the safest dose of the multiple Raf kinase inhibitor (including c-Raf, B-Raf, and the activated mutant B-RafV600E) XL281, how often it should be taken, and how well subjects with cancer tolerate XL281. This study will also determine how the body reacts to XL281 when it is taken with and without food, and with and without Pepcid (famotidine), a drug that inhibits stomach acid production.

This phase I trial studies the side effects and best dose of photodynamic therapy using HPPH in treating patients who are undergoing surgery for primary or recurrent head and neck cancer. Photodynamic therapy (PDT) uses a drug, such as HPPH, that becomes active when it is exposed to a certain kind of light. When the drug is active, tumor cells are killed. Giving photodynamic therapy after surgery may kill any tumor cells that remain after surgery.

This phase II trial studies how well giving sunitinib malate works in treating patients with iodine-refractory recurrent or metastatic thyroid cancer. Sunitinib malate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth or by blocking blood flow to the tumor
