Filter by:While thyroid cancer is generally associated with a favourable prognosis, there is a discrepancy with how important if not traumatic its impact can be on patients. Quality of life (QoL) decreases in the year following a thyroid cancer diagnosis, constituting an optimal period for a preventive intervention. The goal of this study is to evaluate the impact of offering an interdisciplinary team-based care approach for newly diagnosed thyroid cancer patients, including a dedicated nurse who will provide important psychoeducational elements identified in previous focus group studies of thyroid cancer patients, i.e., information on: the physical illness; the emotional impact of being newly diagnosed with thyroid cancer; surgery and its' short- and long-term consequences; radioactive iodine treatments and its associated safety precautions, nutrition and dietary considerations; and how the cancer diagnosis can be an opportunity to make important lifestyle changes and establish new life-priorities.
Thyroid cancer is the most common endocrine malignancy and its incidence is rapidly increasing. Palpable thyroid nodules are very common, affecting up to 5% of the general population. Nevertheless, only 5% of the thyroid nodules harbor malignancy, hence the obvious need to accurately characterise these nodules. Ultrasound guided fine needle aspiration biopsy (FNAB) is the most important tool in assessing the nature of thyroid nodules, however, in up to 30% of the biopsies the results are indeterminate. In this proposal, the investigators hypothesize that leftover cells in the FNAB needle may be utilized for molecular analysis with an established microRNA panel and distinguish between malignant and benign lesions. Despite established studies on the diagnostic utility of microRNAs in thyroid nodules, the effect of microRNAs on specific target genes involved in thyroid cancer is poorly studied. In this proposal the investigators hypothesize that the microRNAs identified in our panel will affect intracellular pathways by regulating target genes that are involved in thyroid tumorigenesis. The investigators present preliminary data that confirms that microRNA panel may identify malignancy in thyroid nodules. In aim 1 the investigators will identify the expression profile of miRNAs in the different thyroid cancers. the investigators will statistically quantify the threshold of miRNA dysregulation for malignancy on a large number of tumor and benign samples. This will serve as matrix for defining malignancy on the FNAB samples. In aim 2 the investigators will establish a reliable reproducible method to extract RNA from cells left over in FNAB samples. the investigators' preliminary data support the feasibility of the method and it has not been described previously. This will be the first study that will compare cytology results and microRNA panel analysis on the very same FNAB cells. It will mimic the exact clinical scenario that such microRNA panel can be utilized in the future. Finally, in aim 3 the investigators will characterize the effect of microRNAs on target genes expression. the investigators will identify possible target genes from bioinformatics databases and will perform quantitative measurement of mRNA level of target gene by real time PCR and immunohistochemistry. These studies will hopefully support the utility of microRNAs as a diagnostic tool to accurately identify malignancy in thyroid FNAB leftover cells and point out possible target genes for future therapeutic approaches. This could impact many patients, as thyroid cancer is the 5th most common cancer in women, and the most rapidly growing malignancy in both men and women.
There 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.
Systemic lidocaine infusion may improve the patients' recovery quality and chronic post surgical pain after robot-assisted thyroidectomy
The purpose of this Phase 2 study is to find out what effect, good and/or bad, external beam radiation therapy, has on the patient and their thyroid cancer where surgery is not an option or where despite surgery, the disease is still present.
The treatment of differentiated thyroid cancer (DCT) includes surgery followed by radioiodine treatment. In the follow-up of patients it is necessary to induce TSH elevation to test for cancer recurrence. One of the options is to stop L-thyroxin replacement for several weeks. Current pilot study aims to induce the necessary TSH elevation by decreasing the L-thyroxin dose. The main hypothesis is that necessary TSH stimulation will be achieved during 4-6 weeks in majority of patients.
The purpose of this study is to determine whether the use of honey mouthwashes in the prevention of salivary side effects of 131I (radioiodine) therapy.
Hypothesis: Dexamethasone reduces postoperative emesis in thyroidectomy and mastectomy patients.
This study will investigate the usefulness of an optical probe in the differentiation of thyroid cancer from normal thyroid tissue in a thyroidectomy specimen.
This study objective is to evaluate the change in mitochondrial uncoupling protein 2 (UCP2) mRNA expression as function of thyroid activity (TSH, T3 and Free T4).
