Filter by:Thyroid surgery is the most common surgical procedure among endocrine surgeries. It is performed in patients with suspected malignancy, patients diagnosed with malignancy, and for toxic nodular goiter [1]. Fine-needle aspiration biopsy (FNAB) is used as a daily technique in preoperative evaluation to differentiate malignant and benign nodules. However, complications including hematoma formation, tumor transplantation along the needle trace, thyroid nodule infarction and vascular proliferation can be seen even in this minimally invasive procedure [2]. Therefore, the differentiation of benign and malignant groups using non-interventional methods before surgery has become important. Cancer-related inflammation, including papillary thyroid carcinoma, is involved in carcinogenesis and progression of neoplastic disease [3,4]. Neutrophils induced by the tumor can accelerate tumor metastasis [3,5]. Lymphocytes, as the cornerstone of the adaptive immune system, inhibit tumor cell proliferation and migration as well as destroying metastases [3,6]. Previous studies have shown that increased lymphocyte count has a positive effect on better survival in patients with advanced cancer [7]. Furthermore, Kupffer cells, also known as liver macrophages, destroy circulating cancer cells and help the distribution of tumor cells via circulation. Therefore, routine blood tests have been investigated as a predictive or prognostic factor for carcinomas since blood parameters in these tests show whether there is inflammation. Neutrophil count, lymphocyte count, neutrophil-lymphocyte ratio (NLR), lymphocyte-monocyte ratio (LMR), mean platelet volume (MPV), and platelet distribution width (PDW) have been studied in terms of numerous malignancies [3]. Tumor-related inflammation is activated the bone marrow and inflammation induced by malignancies. Inflammatory activity that is poorly controlled or uncontrollable may be responsible for malignant transformation [8]. At this point, NLR has previously been shown to be useful in the differentiation of thyroid malignancies and benign thyroid diseases [9]. Delta neutrophil index (DNI) / increased number of immature granulocytes (IG) represents active bone marrow. Delta neutrophil index, which is manifested by IG formation in inflammatory and infectious events, shows changes in the white blood cell count [10]. This study aimed to evaluate the relation between the automatically calculated DNI/IG count and manually calculated NLR from the preoperative complete blood count (CB) parameters, and thyroid malignancies with a cost-effective non-invasive method before surgery or biopsy as the indicator of the malignant inflammatory response in the differentiation of nodular goiter and thyroid malignancy.
This study describes a single center, randomized, single-blinded clinical trial to assess the clinical benefits of the use of near infrared autofluorescence (NIRAF) detection with an FDA-cleared device 'Parathyroid Eye (PTeye)' for identifying parathyroid glands (PGs) during total thyroidectomy (TTx). It compares risk-benefits and outcomes in TTx patients where NIRAF detection with PTeye for parathyroid identification is either used or not used.
Papillary thyroid microcarcinoma (PTMC), defined as a tumor with larger diameter ≤ 1 cm, is considered a tumor with an indolent course and an excellent prognosis. Nevertheless, the incidence of lymph node metastasis in PTMC is not negligible, reaching up to 65% in some series. The aim of this study was to assess the incidence of lymph node metastasis in patients with PTMC and to evaluate predictive factors for lymph node metastasis.
In this study, the investigators detected the expression of SREBP1 in thyroid cancer tissues, explored the biological functions of SREBP1 in thyroid cancer cells.
This study aims to develop a standardized universal imaging protocol for ICG-guided fluorescent total thyroidectomy, including quantitative evaluations of the fluorescent signal. Therefore, patients will undergo thyroid surgery (total thyroidectomy) with the use of ICG fluorescence.
The incidence of Thyroid Cancer (TC) has increased over the last thirty years, in France and worldwide. This increase is mainly due to good prognosis microPapillary TC (mPTC). Sixty percent of diagnosed cancers are considered as over-diagnosed, leading to an over-treatment of these cases. The increase of diagnosis of mPTC and its treatment inevitably leads to an increase of medical resources consumption and corresponding costs. The primary aim of this study is to estimate the cost related to different care management pathway of TC patient during a lifetime period using a multi-state Markov model. This is a retrospective, observational population based cohort study, using data from a cohort study of TC patients implemented by the ONCOMIP network which initially aimed to perform an audit of clinical practices for the management of TC, and from database of the French social health insurance of Midi-Pyrenees region to calculate observed costs of TC management during 24 months.
Although thyroid cancers are low-grade endocrine malignancy, most patients usually received thyroidectomy with ablative radioactive iodine therapy. Such patients were followed with thyroid ultrasonography and serial serum thyroglobulin evaluation. Prior researches indicated that one-third well-differentiated thyroid cancers could transform to poorly-differentiated patterns, even to be anaplastic thyroid cancer (ATC), a fatal malignancy, and no effective therapeutic strategies was noted, including surgical intervention, chemotherapy and radiotherapy. The poorly-differentiated or anaplastic change of thyroid cancer cells proliferates rapidly and always invades local tissues with distant metastasis. Cellular de-differentiation is the most pivotal cause for malignant transformation and invasion. De-differentiation usually in papillary thyroid cancer and follicular thyroid cancer, and definitely in ATC. Therefore, the investigators try to find the biological markers and therapeutic targets via the exosomal expression in urine. On the continuing basis of prior ATC cells culture experiments. Exosomes are nanovesicles secreted into extracellular environments. Cancer cell-derived exosomes could be found in plasma, saliva, urine and other body fluid of patients with cancer. The investigators try to analyze the urinary exosomal proteins, including thyroglobulin and galectin-3, to find the early prognostic biological markers in urine via this prospective study. The investigators expected to enroll 150 post-operative patients with papillary, follicular or anaplastic thyroid cancer, and collect the urine samples in outpatient clinic per year. The investigators will analyze the urine exosomal proteins and probable biological markers, including thyroglobulin and galectin-3. The investigators hope to find the prognostic biological markers via this prospective study. The investigators further hope to find newly therapeutic and follow-up pathway for such patients with well-differentiated or anaplastic thyroid cancer.
This research is being done to better understand and test if the investigators can minimize narcotic medication for controlling pain after thyroid or parathyroid surgery. This research will be performed at Doctors Hospital At Renaissance in the investigators clinic and the perioperative area. Participants will be randomly chosen to receive one of two options for pain management that the investigators are already using in the care of patients after surgery. One option includes a narcotic medication and one option includes a non-narcotic and a narcotic as needed. Participants will be asked to complete a form about the level of pain and how much pain medication was needed after surgery in the hospital and while at home. Participants will not have to do any additional visits to participate in this study. The investigators will obtain the research materials at the same time as the usual care visits around the participants' surgery.
This study investigates the reprogramming of myeloid cells in patients with thyroid carcinoma. The investigators hypothesize that tumor-derived factors change the function of myeloid cells (peripheral blood and bone marrow-derived) in such a way that these immune cells promote tumor growth rather than combat the tumor.
This study evaluates the usefulness of molecular classifier to aid the diagnosis of malignancy in the material obtained by fine-needle aspiration biopsy (FNAB) of thyroid nodule. All participants will undergo FNAB with routine cytological assessment and molecular testing. Patients will undergo surgery or be followed-up, according to the clinical guidelines. The diagnostic power of combined molecular/clinical classifier will be compared to prediction based on clinical features only, by investigators blinded to the final diagnosis of surgical assessment.
