The purpose of this post-marketing surveillance (PMS) is to observe the safety profile of Lenvima (lenvatinib) in normal clinical practice setting.
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.
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
The purpose of this phase Ⅱ study is to assess the efficacy and safety of lenvatinib for anaplastic thyroid cancer patients who are diagnosed as unresectable. The total duration of the study will be 30 months. All patients will start administration of lenvatinib within 1 week of enrollment and receive the study drug 24mg orally once daily at almost the same time. 1 cycle consists of 4 weeks. Treatment term starts on the day 1st of drug administration of cycle 1 and administration will be continued until patients meet withdrawal criteria. Safety and efficacy assesment will be conducted on a regular basis during the trial. Tumor evaluation will be conducted at 4weeks, 8 weeks, 12 weeks, 16 weeks and at every 8 weeks after the 16th week since initial administration. When study drug administration terminated,tests of the drug termination will be conducted within 7 days of withdrawal and final observation will be conducted at 30 days after the last dose. Survival survey will be conducted at follow-up term. After the termination of the study drug, survival follow up survey will be conducted every 12 weeks unless patients withdraw enrollment of this study.
This phase II clinical trial studies how well thermal ablation and spine stereotactic radiosurgery work in treating patients with cancer that has spread to the spine (spine metastases) and is at risk for compressing the spinal cord. Thermal ablation uses a laser to heat tumor tissue and helps to shrink the tumor by destroying tumor cells. Stereotactic radiosurgery delivers a large dose of radiation in a short time precisely to the tumor, sparing healthy surrounding tissue. Combining thermal ablation with stereotactic radiosurgery may be a better way to control cancer that has spread to the spine and is at risk for compressing the spinal cord.
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.
This study is being done because there are currently no approved and no commonly working targeted therapies in anaplastic thyroid cancer (ATC). This is an area of urgent need for patients, not just for approved treatments but also rationally-designed clinical trials designed specifically for ATC. Patients diagnosed with anaplastic thyroid cancer have a very high likelihood of dying because of their disease. As such there is a clear need for improving therapy for ATC.
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.
The investigators evaluated the cardiac effects of Thyroid-stimulating hormone (TSH) over-suppression in women with differentiated thyroid cancer (DTC) frequently encountered during suppression therapy.
