Filter by:The objective of this project is to evaluate a treatment decision aid for patients with low risk thyroid cancer.
The investigators expected to enroll 30 patients with papillary, follicular or anaplastic thyroid cancer, and collect their urine samples before operation, immediately after operation, post-operative 3, 6 12 months. The investigators will analyze the urine exosomal proteins and probable biological markers. The investigators hope to find the prognostic biological markers via this prospective study. The investigators further hope to find newly therapeutic mechanism and medications for such patients with poorly-differentiated or anaplastic thyroid cancer.
When the DNA inside of human cells undergoes certain alterations (mutations), the cells may develop into a cancer. The cancer cells may shed this DNA into the blood stream. This circulating tumor DNA (ctDNA) can be detected by very sensitive, specialized laboratory tests. Measurement of ctDNA has been shown to be useful for following patients with known cancer. The purpose of this study is to examine blood specimens for the presence of ctDNA in individuals without known cancer who are scheduled to undergo a fine needle aspiration biopsy of the thyroid gland because of one or more thyroid nodules in order to see if the ctDNA test can detect a cancer at a very early stage. The results of this study should help define the role of ctDNA in the detection of early stage thyroid cancer and to define how sensitive it is (i.e. how well it picks up cancer when it is present) and how specific it is (i.e. how often is ctDNA found in patients with benign thyroid nodules).
Thyroid cancer affects 6,000 Canadians each year. Nodules on the thyroid are detected using ultrasound imaging and surgery is the most common treatment. However, most nodules are benign, and therefore a biopsy is needed to decide whether surgery is necessary. Ultrasound imaging is very sensitive for localizing nodules, but does not differentiate between cancerous and benign ones. To address this limitation of US imaging, investigators have designed and constructed, in collaboration with Sogang University, Seoul, S. Korea, a novel imaging system that performs complimentary imaging modalities (ultrasound (US), photoacoustic (PA)) that could potentially help diagnose nodules without the need for biopsy and unnecessary surgery.
Thyroid cancers can occur sporadically, but can also be found as tumors that cluster in families with other cancers or genetic syndromes. Researchers are studying thyroid cancer in children and families, with a particular interest in understanding genes and other factors that may put individuals at risk for developing thyroid cancer and thyroid nodules. - In this study, family and medical history information is collected alongside a blood or saliva sample for genetic studies. - Individuals with a past or present childhood thyroid cancer/nodule or a thyroid cancer suspected to be inherited in their family are invited to participate.
The purpose of this study is to assess the efficacy and safety of apatinib in locally advanced/metastatic radioactive iodine-refractory/resistant differentiated thyroid cancer
To explore how a clinical sample of patients with thyroid nodules (men and women) with no history of thyroid cancer would make decisions about treatments based on different terminology used to describe papillary thyroid cancer (with and without the cancer term).
This is a multicenter, randomized, double-blind study being conducted as a postmarketing requirement to the US Food and Drug Administration (FDA) to evaluate whether there is a lower starting dosage of lenvatinib 24 mg once daily (QD) that provides comparable efficacy but has a better safety profile in participants with radioiodine-refractory differentiated thyroid cancer RR-DTC with radiographic evidence of disease progression within the prior 12 months.
Recently published European guidance recommends the evaluation of the radiation dose to the bone marrow in patients undergoing radioiodine therapy for thyroid cancer. The methods described in these guidelines require serial blood samples to be taken from the patient, followed by a sophisticated analysis to determine the radiation dose. However, radiation risk assessments carried out locally have indicated that a relatively high radiation exposure will be received by the operator taking the blood samples, which may prohibit this procedure being carried out routinely. The radiation dose to the operator will be lowered if the duration of the blood sampling procedure were reduced. The investigators hypothesize that the use of a lancet and pipette to collect blood from the finger tip will greatly reduce the time spent in proximity to the patient, significantly reducing the operator exposure and allowing this procedure to be performed routinely. The proposed method is also less invasive for the patient compared to the intravenous sampling recommended in the guidelines. A proof-of-principal pilot project using radioiodine diluted to the expected concentration in blood has indicated that using very small volumes of blood (such as from a lancet) does not compromise the accuracy of the dosimetry measurement when compared to large-volume standard blood samples. The primary aim of this study is to investigate whether sampling a small volume of blood using a lancet and pipette can replace standard intravenous blood samples for bone marrow dosimetry in patients undergoing radioiodine treatment for thyroid cancer. Statistical tests will determine whether there is a significant difference between the doses calculated using each blood sampling method. In addition, the investigators will measure the radiation exposure received by the operator during each procedure using Electronic Portable Dosimeters. The results of these measurements will be used to quantify the reduction in operator radiation exposure afforded by the new technique.
This research study is studying a targeted therapy as a possible treatment for thyroid cancer. A targeted therapy is a type of treatment that uses drugs or other substances to identify and attack specific types of cancer cells with less harm to normal cells. - The name of the study intervention involved in this study is regorafenib.
