Filter by:The 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.
Recently, targeted next generation sequencing (NGS) platforms have been introduced that allow inexpensive testing for hundreds of mutational hotspots at the same time. A number of additional mutational markers in thyroid cancer have been identified. Highly promising markers associated with tumor prognosis have also been found. This multi-institutional study aims to validate the diagnostic use of mutational markers in thyroid nodules with indeterminate cytology. The proposed hypothesis is that a broad NGS-based genotyping of thyroid nodules using a large panel of mutational markers applied to thyroid FNA samples can provide an accurate cancer risk stratification in thyroid nodules. The performance of the panel will be tested in a multi-institutional double-blind prospective study of FNA samples from thyroid nodules with indeterminate cytology and available surgical outcome
To determine the improvement in diagnosis of papillary carcinoma by detecting mutation V600E BRAF in retrospective cases with inconclusive cytologic diagnosis (categories III, IV and V of Bethesda System)
Prospective, open label single site study to demonstrate the safety and efficacy of Tc-99m pertechnetate produced by high energy cyclotron at CHUS.
Postmenopausal women with differentiated thyroid cancer (DTC) taking suppressive doses of levothyroxine (L-T4) are thought to have accelerated bone loss and increased risk of osteoporosis. Therefore, the investigators try to investigate the effects of 99Tc-MDP,alendronate sodium in postmenopausal women with DTC under TSH suppression and osteoporosis.
The aim of this study is to compare the results of total thyroidectomy using the Thunderbeat device to that with the harmonic scalpel.
The purpose of the study was to assess the use of Multikinase Inhibitors (MKIs) in the treatment of patients with a progressive differentiated thyroid carcinoma (DTC) refractory to radioactive iodine (RAI) who do not have any symptoms.
The purpose of the study is to find out if the small dose of radioiodine, that is used for the dosimetry study on patients with differentiated thyroid cancer, may stun the cancer cells and make the thyroid cancer treatment less effective.
Vandetanib has been approved for patients with unresectable and/or metastatic medullary thyroid cancer (MTC) by the Food and Drug Administration, by the European Medicines Agency and, very recently, it has been licensed also by the Italian Regulatory Agency (AIFA) for the use in Italy. Vandetanib is an orally tyrosine kinase inhibitor (TKI) of vascular endothelial growth factor receptor (VEGFR), epidermal growth factor receptor (EGFR), and RET signaling. Circulating microRNAs levels could be influenced by the treatment procedures and we hypothesize that a TKI therapy could influence the levels of circulating miRNAs as well. Aim of this project is to seek non-invasive molecular markers potentially useful as prognostic tools for metastatic MTC patients.
