Filter by:Contrast-enhanced ultrasound (CEUS) can sensitively show the blood perfusion characteristics of thyroid nodules, which is a useful supplement to gray-scale ultrasound. However, there is no standard combined diagnostic method of gray-scale ultrasound and CEUS. Therefore, the aim of this study was to compare the diagnostic performance of the integrated scoring method and the up-and-down scoring method. This study was a multicenter retrospective clinical study and followed the Standards for Reporting of Diagnostic Accuracy Studies (version 2015). Inclusion criteria: 1) participants with at least one thyroid nodule larger than 5 mm confirmed by conventional ultrasound; 2) participants underwent gray-scale ultrasound, contrast-enhanced ultrasound and fine needle aspiration biopsy of the thyroid nodule successively; 3) participants have a final diagnosis of benign or malignant. Exclusion criteria included: 1) participants with cytologic findings of Bethesda I, III, or IV without definitive benign or malignant pathologic findings; 2) participants with a history of thyroid fine needle aspiration, ablation or surgery; 3) participants with low quality ultrasound images (e.g., severe artifacts or low image resolution). According to the American College of Radiology Thyroid Imaging Reporting and Data System, only one thyroid nodule with the highest point was included in each participant. A total of 600 participants from January 2018 to December 2022 were consecutively included in Sun Yat-sen Memorial Hospital of Sun Yat-sen University to form a training set (average age 48 years; Range 24-81 years old). A total of 200 subjects with thyroid nodules from January 2022 to December 2022 were consecutively included to form an external validation set in Houjie Hospital of Dongguan City, Guangdong Province (mean age 46 years; Range 30-74 years). The malignant risk of enrolled thyroid nodules and the necessity of biopsy were evaluated by integrated scoring method and up-and-down scoring method, respectively. The diagnostic performance and unnecessary biopsy rate of the above two methods were calculated and compared.
The study hypothesis is that a lower starting dose of anticancer tablet treatments can lead to better treatment tolerability in older patients, while the benefits of treatment can be the same. The trial population consists of 30 patients aged 65 years or older, who are starting treatment with one of these anti cancer tablet treatments: pazopanib, olaparib, lenvatinib, sunitinib or palbociclib. The control group (half of the participants) will be treated with the standard-of-care, the interventional group will start with the lowest dose of the anti cancer tablets as described in the drug label. The dose will be increased every two weeks in case of good tolerability. Results of this pilot study will be used to inform the design of the larger randomised phase 2 trial.
Endoscopic thyroidectomy has been used to treat thyroid diseases in China. However, whether this technique is rational to treat thyroid carcinoma is still in controversy. The diagnosis of thyroid carcinoma is predominantly made according to intra-operative frozen section pathological examination in China. In this research, the investigators want to compare clinical index (blood loss, operation duration, number of lymph nodes dissected, complication rates, etc) between patients underwent endoscopic thyroidectomy ( total thyroidectomy) and those underwent conversion to open procedure. The investigators want to evaluate the technical feasibility of endoscopic thyroidectomy for treating thyroid carcinoma.
