Filter by:This clinical trial is looking at a combination of drugs called vemurafenib and cobimetinib. Vemurafenib is approved as standard of care for adult patients with unresectable or metastatic melanoma. Cobimetinib is approved as standard of care in combination with vemurafenib for the treatment of adult patients with unresectable or metastatic melanoma. Cobimetinib and vemurafenib work in patients with these types of cancers which have certain changes in the cancer cells called BRAF V600 mutation-positive. Investigators now wish to find out if it will be useful in treating patients with other cancer types which are also BRAF V600 mutation-positive. If the results are positive, the study team will work with the NHS and the Cancer Drugs Fund to see if these drugs can be routinely accessed for patients in the future. This trial is part of a trial programme called DETERMINE. The programme will also look at other anti-cancer drugs in the same way, through matching the drug to rare cancer types or ones with specific mutations.
Somatic mutations in the MAP (mitogen-activated protein) kinase pathway have been found in about 80% of papillary thyroid tumors (PTCs). The evaluation of the PTC mutational profile is crucial for the definition of the prognosis and for predicting the effects of targeted and personalized therapies. Molecular characterization by mass spectrometry (Mass ARRAY) allows the search for multiple mutations in a single experiment, in a sensitive, fast and economic way. A Mass ARRAY platform (PTC-MA) was developed, capable of identifying the presence of the most common somatic point mutations and rearrangements in PTC (Pesenti et al., Endocrine 2017). The aim of the study is to characterize the mutational profile of a large series of papillary thyroid carcinomas (PTC). Tumor samples will be analyzed using our PTC-MA platform. The molecular profile of PTCs will be correlated with the clinical and prognostic characteristics of the patients.
The goal of this retrospective study is to compare the safety and efficiacy of endoscopic thyroidectomy via retro-auricular single-site approach, transoral endoscopic thyroidectomy vestibular approach and transareola approach.
Oxidative stress (OS) could be involved in the progression of papillary thyroid cancer (PTC). Indeed, thyroid differentiation genes are silenced by a mechanism controlled by NOX4-derived OS. On the other hand, TERT contributes to mitochondrial OS protection, which could increase the resistance of cancer cells to therapeutic agents. The investigators aim to address the role of OS and mitochondrial TERT in the progression and therapeutic resistance of PTC. OS and TERT subcellular localization will be investigated in 150 PTCs and correlated to the genetic and expression profile of the tumors and to the clinical and prognostic features of the patients. Mechanisms implicated in TERT mitochondrial migration and the contribution of mitochondrial TERT to tumor progression will be investigated in cancer cell lines and primary cell cultures. This study will allow to identify OS as a marker of therapeutic resistance in PTC and will open new opportunities for the development of novel treatments targeting ROS generation/TERT nuclear export.
Thyroid cancer is a common head and neck malignancy. It is the most common endocrine tumor in the body accounting for 1% of all cancers worldwide. The incidence of thyroid cancer varies worldwide. Most countries have reported an upward trend in its incidence. Thyroid cancer encompass the most common well-differentiated papillary carcinoma (80% of all thyroid cancers) and follicular carcinoma (15%), as well as poorly differentiated carcinoma (< 1%) and anaplastic carcinoma (< 2%). Papillary thyroid carcinomas (PTCs) are the most commonly encountered thyroid malignancies. The diagnosis of PTC is based on the special nuclear features such as overlapping of nuclei, intranuclear inclusions, optical clearing, anisonucleosis and nuclear grooves. However, it is often difficult to differentiate PTC from benign papillary thyroid hyperplasia . As differentiation between benign or malignant thyroid lesions has clinical, therapeutic, and prognostic significance, it is necessary to make accurate diagnosis by using biomarkers. Recently, a large number of immunohistochemical (IHC) markers have been studied to assist in differentiating non-neoplastic lesions from malignant thyroid lesions. CK19, galectin-3, TG, Ki67, BRAF, calcitonin, HBME-1, TTF-1, and RET are some of the examples of these IHC markers. Galectin-3 is a 31-kDa β-galactoside binding lectin. It has been shown to be expressed by several types of non-neoplastic and neoplastic cells, and it is involved in cell-cell adhesion and in cell-matrix interactions.
This is a Phase 1/2, open-label, first-in-human (FIH) study designed to evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), and preliminary antineoplastic activity of TY-1091 administered orally in participants with medullary thyroid cancer (MTC), RET-altered NSCLC and other RET-altered solid tumors.
This research is being done to determine the efficacy of selpercatinib to restore radioactive iodine (I-131) uptake and allow for I-131 treatment in people with RET fusion-positive radioiodine-refractory thyroid cancer. This research study involves the study drug selpercatinib in combination with standard of care treatments, I-131 and thyrotropin alfa (rhTSH).
This phase II study evaluates F-18 tetrafluoroborate (18F-TFB) PET/CT scan in patients with differentiated thyroid cancer. Diagnostic imaging is necessary for planning treatment, monitoring therapy response, and identifying sites of recurrent or metastatic disease in differentiated thyroid cancer. 18F-TFB PET/CT may accurately detect recurrent and metastatic thyroid cancer lesions, with the potential to provide information for patient management that is better than the current standard of care imaging practices.
To evaluate the feasibility and safety of gasless transaxillary posterior endoscopic thyroidectomy (Resection of thyroid lobe and isthmus, lymph node dissection in the central area of the affected side) and open radical thyroidectomy (Resection of thyroid lobe and isthmus, lymph node dissection in the central area of the affected side) as the current standard surgical treatment mode in terms of feasibility and safety of radical thyroidectomy.
Non-medullary thyroid carcinoma has a good prognosis in most patients. However, a small subset of patients nevertheless develop metastatic or locally advanced and unresectable disease which in some cases also becomes radioiodine refractory. In these patients treatment options are very limited. Earlier cell line and animal studies have shown that digoxin can reinduce radioiodine uptake in non-medullary thyroid cancer. This study serves as a proof of principle study to assess the possibility of digoxin to reinduce radioiodine uptake in adult humans with metastatic or locally advanced non-medullary radioiodine refractory thyroid carcinoma.
