Health-Related Quality of Life for Thyroid Patients

Thyroid Diseases

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.

Clinical Evaluation of a New Highly Sensitive Thyroglobulin Assay in Differentiated Thyroid Carcinoma...

Thyroid Neoplasms

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.

Assessment of Quality of Life After Adjunct Radioiodine Therapy in Patients With Differentiated...

Thyroid Neoplasms

The aim of this study was to assess the impact of adjuvant radioactive iodine therapy on the quality of life(QOL) in differentiated thyroid cancer patients and to identify independent factors affecting changes in the QOL.

Application of Ultrasonic Gray-scale Ratio in Differentiating Benign From Malignant Thyroid Nodules....

Thyroid Nodule

According to the grades of echogenicity to evulated thyroid nodules is a subjective process and is thus influenced by the observer's judgement. The investigators first proposed the ultrasound gray-scale ratio (UGSR) to explore its efficacy for differentiating papillary thyroid microcarcinomas from small nodular goiters.

The Effect of Iodine and BPA on AITD in Reproduction Women

Autoimmune thyroid disease (AITD) is the main cause of hypothyroidism in reproduction women, iodine and bisphenol A are the environmental factors for AITD. The research was mainly designed to investigate the effect of iodine and BPA on AITD in reproduction women to provide new evidence for hypothyroidism in reproduction women.

Identification of Molecular Biomarkers for Thyroid Cancer

Thyroid Cancer

This is a two part study; part A proposes to collect plasma samples to examine how ctDNA (circulating thyroid DNA) markers correlate with detection of recurrent disease, response to therapy, clinical outcome and pathological data. Part B aims to use tissue obtained from biopsies of primary or recurrent disease to establish cell lines and tumour explants to further investigate the biology of thyroid cancer in the preclinical setting

An Assessment of Aspirin Plus Prednisone Treatment for Euthyroid Women With Thyroid Autoimmunity...

Thyroid Diseases

Thyroid autoimmunity(TAI) per se have adverse effect on pregnancy outcomes,and aspirin and prednisone were used frequently in antithyroid antibodies(ATA) positive infertile women in clinical practice, but the impact of these medicines is still controversial. Therefore, aim of the study was to investigate whether or not the treatment of prednisone in addition to aspirin was capable of improving reproductive outcomes in euthyroid infertile women.

Differentiated Thyroid Cancer

To find out the gap between real-world clinical practice and guideline recommendations in initial management of DTC patients To observe the characteristics of patients who achieved and did not achieve TSH target value after five year follow-up To assess response to initial therapy in patients who undergo total or neartotal thyroidectomy and RAI remnant ablation after five year follow-up (according to an modified dynamic risk stratification system) To observe the recurrence status after five year follow-up

Correlation Between TCM Syndrome Factors and TSH Changes of Thyroid Hormone Withdrawal Before Iodine...

Differentiated Thyroid CarcinomaTCM Syndrome Type

The purpose of this study is to make a dialectical classification of patients who will receive 131I treatment after operation of thyroid cancer from the point of view of dialectics of syndrome elements of traditional Chinese medicine. By observing the changes of TSH among patients with different syndrome types, investigators can better understand the reasons for the differences in TSH changes among patients. Thus, it provides a basis for putting forward the scheme of stopping taking levothyroxine before iodine treatment, improving the quality of life of patients after radical thyroidectomy, and providing reference for individualized guidance of the timing of radioactive iodine therapy for patients after DTC.
