Potential Role for Carbon Nanoparticles to Guide Central Neck Dissection in Patients With Papillary...
Thyroid CancerPapillary 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.

Pembrolizumab in Recurrent or Metastatic Medullary Thyroid Cancer
Medullary Thyroid Cancer (MTC)Background: Medullary thyroid cancer (MTC) is a tumor of the thyroid gland. Surgery is the only current treatment to cure it. The drug pembrolizumab (MK-3475) is a new type of cancer therapy. It works by allowing the immune system to detect and kill tumor cells. Objective: To test how pembrolizumab affects people with MTC and if it can offer them clinical benefit. Eligibility: People ages 18 and older with MTC Patients who have recurrent or metastatic MTC, for whom surgery is not a curative option Patients with some imaging evidence of MTC Patients with minimal symptoms related to MTC Design: Participants will be screened with: Medical history Physical exam Blood, urine, and heart tests Computed tomography (CT) scan or magnetic resonance imaging (MRI): They lie in a machine that takes pictures of the body. Bone scan Participants will be put in a group based on their treatment history: Group 1 if they have had an immune stimulating cancer vaccine Group 2 if they have had no vaccine Participants will receive the study drug as a 30-minute intravenous (IV) infusion every 3 weeks. Treatment will continue for up to 2 years as long as they tolerate it and their disease does not get worse. Participants will have physical exams and blood tests on the day of each infusion. They will have CT and bone scans every 3 months. Participants may save biopsies before treatment and after starting treatment. Participants will have a final visit 3-4 weeks after stopping treatment. This will include a physical exam and blood and heart tests. After this study, participants can join a long-term follow-up study.

Effects of Radioactive Iodine on the Immune System in Thyroid Cancer
Thyroid CarcinomaNonmedullaryBlood 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.

An Open-label, Multicenter, Phase II Study of Dovitinib in Advanced Thyroid Cancer
Thyroid CancerThere has been no effective treatment for advanced thyroid cancer that is not amenable to surgery and that does not concentrate iodine. Response rates with chemotherapy have been so low that best supportive care has been the standard of care for most patients. In recent phase I and phase II clinical studies, dovitinib has shown activity as a single agent in solid tumors. Therefore, we will conduct a phase II, single-arm trial to determine the efficacy of dovitinib in radioactive iodine-refractory recurrent or metastatic thyroid cancer.

Efficacy of Radium 223 in Radioactive Iodine Refractory Bone Metastases From Differentiated Thyroid...
Thyroid CancerThe purpose of this Phase II single-arm study is to evaluate the efficacy of Radium-223 in treating bone lesions from differentiated thyroid cancer that are I-131 refractory. Based on the results of the phase III trial, the protocol using an injection of Radium-223 activity of 50 kBq/kg b.w. given 6 times at 4 weeks interval will be applied. The end point of this study will be the evaluation of Radium-223 efficacy one month after 3 administrations, i.e. at 3 months after the first injection. If disease progression at that time is excluded, patients will be treated with 3 further injections for a total of 6 administrations of Radium-223. The principal response criterion at 3 and 6 months will be the metabolic response on FDG PET/CT, but other imaging techniques will also be performed: axial skeleton MRI, 99mTc-HMDP bone scan and FNa PET/CT. Axial skeleton MRI is the reference for soft tissue study. 99mTc- HMDP bone scan is the most used and available routine tool to detect bone metastases in cancer patients, but its sensitivity in patients with bone metastases from thyroid cancer is low, because most lesions are lytic [23]. 18FNa PET/CT shows higher sensitivity than 99mTc-HMDP bone scan to detect bone lesions in cancer patients and is able to detect micrometastases that are not seen on bone scan [24] [25]. Preliminary results show some interest of using this tracer to evaluate the sclerotic component of bone metastases from thyroid cancer [26]. Furthermore preliminary data show that FNa PET/CT can be useful to quantify response to Radium-223 in prostate cancer. In only five patients evaluated by FNa PET/CT at baseline, 6 weeks and 12 weeks after 100 KBq/Kg of Radium-223, semiquantitative analysis by SUV max showed a relationship between PSA and SUV max level decrease in 3 patients (-44%, -31%, -27% vs -52%, -75, and -49% respectively) [27]. Finally bone metastases that are visible on morphological imaging (CT scan or on RI) are frequently submitted to local treatment modalities, and this may induce fibrosis and recalcification. Therefore, already treated metastases and not treated metastases will be studied separately as two separate subgroups of target lesions.
