Filter by:Nodular goitre is common in the general population and less than 5% of the patients who undergo surgery for solitary thyroid nodules have cancer, in absence of clinical suspicion. Nodules left untreated seem to have a slight growth potential in borderline iodine-deficient areas. Interstitial laser photo-coagulation (ILP) is a procedure for local hyperthermia and photocoagulation, allowing minimally invasive treatment of benign tumors, including thyroid nodules. The aim of these studies are to evaluate if ILP will be useful in reducing the volume of the benign thyroid nodule and thyroid function will be unaffected in euthyroid patients, and normalized in pretoxic- and toxic thyroid nodules. The investigations are listed below: 1. Randomized study of interstitial laser photocoagulation for benign solitary cold thyroid nodules – one versus two or three treatments 2. Randomized study of interstitial laser photocoagulation for benign solitary autonomous thyroid nodules – 131I versus laser ablation 3. Interstitial laser photocoagulation for benign thyroid cystadenomas. – a feasibility study.
Background: Thyroid diseases are frequent. They include both metabolic changes and gland enlargement (goitre). Previous research and clinical suspicion indicate that the life quality of many patients is reduced despite successful treatment. Research methods are, however, weak, and a well-tested, disease specific quality of life questionnaire is especially needed. Several treatment possibilities exist for each thyroid disease. For example, hypermetabolism can be treated with either medication, radioactive iodine or by surgery. No comparative studies of quality of life using the different treatment modalities exist. Purpose: To develop and evaluate a questionnaire to measure health-related quality of life in patients suffering from thyroid diseases. Methods: To ensure that all relevant aspects are included, the questionnaire will be developed on the basis of a systematic examination of the scientific literature and interviews with 13 physicians and 100 patients. The questionnaire will then be tested by 100 new patients. After revision, the questionnaire will be answered by 1000 patients with a view to scientifically investigate the measuring capacity of the questionnaire. This will be done using traditional psychology methods (psychometry) as well as modern statistical methods (structural equations for categorical data and "item response" models). Relevance: The above-mentioned questionnaire is necessary for clarifying whether these diseases reduce quality of life and, in the long-term, whether a difference in quality of life exists using the different treatment alternatives and whether treatment can be improved. It should also be included in quality protection studies, in the evaluation of new treatment modalities and possibly also in the treatment of the individual patient.
Human thyroglobulin (Tg) is the most sensitive biochemical marker for recurrence of differentiated cancer (DTC), especially after the complete removal of thyroid tissue through surgery and radioiodine therapy (RIT). Unfortunately, current assays for measuring Tg in blood samples are not sensitive enough to reliably measure Tg while patients are under thyroid hormone replacement therapy. Instead patients have to withdraw thyroid hormone for several weeks or receive costly injections of recombinant thyroid stimulating hormone (TSH) in order to raise Tg production by thyroid remnant and/or thyroid cancer cells so that it can be measured by current Tg assays. Other patients have antibodies against Tg that interfere in current immunoassays. The purpose of the study was to characterize a new highly sensitive assay for measuring Tg in the serum in thyroid cancer patients both on thyroid hormone therapy and off therapy in comparison to the normal routine assay already in use at Münster University Hospital.
The trial examines the clinical benefit of adjuvant external beam radiotherapy (RTx) for locally invasive differentiated carcinoma (TNM stages pT4 pN0/1/x M0/x; 5th ed. 1997) of the thyroid gland (DTC). Patients are treated with surgery (thyroidectomy and lymphadenectomy), radioiodine therapy (RIT) to ablate the thyroid remnant tissue, and TSH-suppressive L-thyroxine therapy with or without RTx after documented elimination of cervical I-131 uptake.
This phase II trial is studying how well suberoylanilide hydroxamic acid works in treating patients with metastatic and/or locally advanced or locally recurrent thyroid cancer. Drugs used in chemotherapy, such as suberoylanilide hydroxamic acid, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Suberoylanilide hydroxamic acid may also stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
This phase II trial is studying how well sorafenib works in treating patients with advanced anaplastic thyroid cancer. Sorafenib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor.
Irofulven is an investigational chemotherapeutic agent being studied in a variety of solid tumors. The purpose of this study is to assess the efficacy and safety of irofulven/capecitabine combination therapy in patients with anaplastic, medullary, or locally advanced/metastatic differentiated thyroid cancer.
The purpose of the study is to determine if AMG 706 will have clinically meaningful anti-tumor activity in subjects with locally advanced or metastatic thyroid cancer who are not candidates for radioactive iodine therapy or local therapies.
This phase II trial is studying how well tanespimycin works in treating patients with inoperable locoregionally advanced or metastatic thyroid cancer. Drugs used in chemotherapy, such as tanespimycin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing.
The thyroid cells take up iodine, and radioactive iodine is commonly used to irradiate residual thyroid tissue and thyroid cancer following surgical removal of the thyroid gland (thyroidectomy). A whole body radioactive iodine scanning is usually carried out after thyroidectomy to assess the amount of thyroid tissue left behind at surgery (that might still contain cancer), and to evaluate the presence of iodine avid lesions elsewhere in the body (that might be cancer metastases). A large dose of radioactive iodine is often given, still the optimal iodine dose to ablate the thyroid remnant after surgery is not known. In this study, two radioactive iodine doses are compared in the ablation of the thyroid remnant, a smaller (1110 MBq) dose and a larger (3700 MBq) dose. The study participants are randomly allocated using a 1:1 ratio to receive either the smaller or the larger radioactive iodine dose. These treatments are compared for safety, adverse effects, and the need for subsequent repeat treatments. The individual absorbed radiation doses are measured. The study hypothesis is that fewer repeat radioiodine treatments might be needed after the larger dose, but the larger dose might be associated with a higher frequency of adverse events.
