Active clinical trials for "Thyroid Nodule"

When a patient presents with a thyroid mass, part of the work-up may include a fine needle aspiration biopsy (FNAB). The results of the biopsy then help plan treatment. If the results are benign, the management will typically be to follow the nodule. If the results demonstrate or are suspicious for cancer, such as papillary thyroid carcinoma (PTC), the treatment is a total thyroidectomy (total thyroid removal). The latest American thyroid association guidelines for PTC (2009) suggest that in many instances a central lymph node dissection (CLND) should be performed in conjunction with the total thyroidectomy. This procedure consists of removing the lymphatic (glandular) tissues surrounding the thyroid itself, as this tissue may have a propensity for cancer spread. The procedure's necessity has met much controversy in the last decade, but is becoming more of a standard in thyroid cancer surgery. When a thyroid nodule FNAB is reported as indeterminate, the treatment strategy is less clear cut. While a diagnostic hemi-thyroidectomy or therapeutic total thyroidectomy may be in order, the inclusion of CLND is not clearly defined. In many centers a CLND will be omitted with surgical management for an "indeterminate" lesion, while in others, it is standard protocol. The argument of performing CLND is largely based on the tenet that it adds little surgical time, cost or risks to the patient. Because the evidence of the prognostic role of lymph node metastases is limited many would argue that the risk of not performing CLND is greater than performing CLND. Furthermore, in the event of finding cancer on final pathology, and thus, having to re-operate in the thyroid/central compartment bed, post-operative complications may increase. Opponents of CLND argue that there is a paucity of strong evidence supporting CLND in the improvement of oncologic outcomes and can potentially increase post-operative low calcium levels or vocal nerve damage However, these recommendations are based on retrospective level III evidence. Thus the debate continues: is CLND justified as an adjunct to hemi-or total thyroidectomy in indeterminate thyroid pathology? The hypothesis is: CLND in hem- or total thyroidectomy for "indeterminate" thyroid nodules will not increase post-operative complications.

The main objective is to compare 12 month complication rates between a new surgical method for thyroidectomy (robot-assisted endoscopic thyroidectomy via a sub-clavical approach) and open thyroidectomy.

The cases that fulfill the inclusion criteria will be enrolled with written informed consent. Images and videos will be collected in accordance with the procedure, uploaded to Ruiying Cloud, followed up, and registered with basic case information, such as thyroid function, FNA/surgical pathology results, etc.

To study the value of thyroid artificial intelligence diagnosis system and fine needle puncture in the diagnosis of benign and malignant thyroid nodules, so as to provide evidence-based medical evidence for the diagnosis of benign and malignant thyroid nodules by artificial intelligence.

The purpose of this study is to evaluate thyroid nodule's volume, structure and vascularisation changes following HIFU therapy assessed by ultrasonography

There is no scientific data on post-thermal ablation cytological aspects, but treated nodules that grow back significantly after a procedure justify a new cytology in order not to ignore a neoplastic process. The EU-TIRADS classification usually used to stratify the risk of cancer (and to justify a fine needle aspiration biopsy) of thyroid nodules is not validated for nodules treated by thermal ablation (TA) (post-RF nodules). However, these nodules often acquire ultrasound criteria of suspicion making it necessary to develop an ultrasound stratification of the risk of malignancy specific to nodules treated by TA. The objective of this work is to describe the ultrasound and cytological aspects of these treated nodules by performing a systematic assessment at 3 years after thermal ablation including systematic neck ultrasound and fine needle aspiration biopsy. Thus, an ultrasound and cytological atlas (Bethesda classification 2017) of nodules treated by thermal ablation will be constituted.

High Intensity Focused Ultrasound (HIFU) is a new approach in treating benign thyroid nodule without surgery. It is proven effective and safe relative to traditional surgery. From previous HIFU studies, it caused shrinkage of thyroid nodule up to 70% from original size. Unfortunately, 5-10% of nodule do not shrink. Those which do not shrink are usually large in size and therefore a second HIFU treatment may help. This study is going to evaluate the efficacy and safety of reapplication HIFU after the first single HIFU session in 6 months. The study will be carried out in the following steps: Recruit subject from the clinic according to the study criteria. Arrange the reapplication HIFU treatment within 3 months. Arrange 4 visits after the HIFU treatment in Post 7 days, Post 1 month, Post 3 months, and Post 6 months; Data collection will be in these 4 visits through the questionnaire or interview by research assistant The subjects will have further health management with the same team after the study.

In transoral thyroidectomy via vestibular approach (TOETVA), prophylactic antibiotic for 5~7 days is recommended for the clean-contaminated wound. In this study, the investigators design a 2-day versus 7-day antibiotic prophylaxis to compare the surgical result and infection rate.

Thyroid gland diseases are the second most common endocrine disease following diabetes mellitus(1). Thyroid nodules are common disorders with a prevalence ranged from 4 to 7% in adult population, 5%-30% are malignant [1].Fine-needle aspiration cytology (FNAC) is an easy, cost-effective test for cancer diagnosis, and its use has markedly decreased the number of unnecessary thyroid surgeries(2).

To evaluate the short-term efficacy of high intensity focused ultrasound (HIFU) in the treatment of benign thyroid nodules
