Active clinical trials for "Thyroid Neoplasms"

This clinical trial studies how well ultrasound elastography works in assessing the cancer status of potentially malignant thyroid nodules.

study assigned into three groups, Group I was the control group operated by total thyroidectomy and retrospectively followed, where the other two groups Operated by Total thyroidectomy and central neck dissection. Recurrence Free Survival (RFS) was the main issue of the study and calculated as the time from date of surgery to date of relapse or the most recent follow-up contact that patient was known as relapse-free, Study exclusively studied the outcome and advantage of central neck dissection

Thyroid cancer affects 6,000 Canadians each year. Nodules on the thyroid are detected using ultrasound imaging and surgery is the most common treatment. However, most nodules are benign, and therefore a biopsy is needed to decide whether surgery is necessary. Ultrasound imaging is very sensitive for localizing nodules, but does not differentiate between cancerous and benign ones. To address this limitation of US imaging, investigators have designed and constructed, in collaboration with Sogang University, Seoul, S. Korea, a novel imaging system that performs complimentary imaging modalities (ultrasound (US), photoacoustic (PA)) that could potentially help diagnose nodules without the need for biopsy and unnecessary surgery.

The aim of this study is to optimize pretargeting parameters using pharmacokinetic and imaging data for immuno-PET using anti-CEA x anti-HSG TF2 BsMAb and 150 MBq of 68Ga-IMP-288 peptide in MTC patients with abnormal Ct serum level after initial complete surgery and at least one abnormal lesion

The treatment of differentiated thyroid cancer (DCT) includes surgery followed by radioiodine treatment. In the follow-up of patients it is necessary to induce TSH elevation to test for cancer recurrence. One of the options is to stop L-thyroxin replacement for several weeks. Current pilot study aims to induce the necessary TSH elevation by decreasing the L-thyroxin dose. The main hypothesis is that necessary TSH stimulation will be achieved during 4-6 weeks in majority of patients.

The purpose of this study is to prospectively analyze the incidence of occult lateral neck metastasis (LNM) and to elucidate the factors that predict LNM in papillary thyroid carcinoma (PTC) with central neck metastasis (CNM) by performing prophylactic selective lateral neck dissection (SND).

The aim of our study is to evaluate the ultrasonic scissors (Harmonic Focus Ethicon Endo-Surgery Laboratory) as a device of hemostasis in thyroid surgery (total thyroidectomy) by cervicotomy, and to show a decrease in transient hypoparathyroidism compared to conventional techniques of haemostasis (clips, ligatures, and bipolar coagulation). Secondary objectives of the study are the evaluation of (i) recurrent nerve morbidity, (ii) postoperative bleeding, (iii) postoperative pain, (iv) cost of both techniques (microcosting), (v) the overall cost of the techniques at six months, (vi) a linking of costs and medical outcomes and (vii) an estimation of the potential impact of new technology on the organization of operating rooms (operating time).

The purpose of this study is to determine [for patients with previously treated well-differentiated thyroid cancer and evidence of residual disease based on serum thyroglobulin (Tg) level] whether positron emission tomography-computed tomography (PET-CT) fusion scanning performed after recombinant thyroid-stimulating hormone (TSH) (rTSH, thyrotropin alfa for injection) will be more sensitive for the detection of disease sites than PET-CT scanning without rTSH. The study will also determine if this information will significantly alter the therapeutic approach in some patients.

Malignant pleural mesothelioma (MPM) has a growing incidence and in spite of early diagnostic, their outcome remains dismal. The evolution of MPM is often local with rare distant metastases. There is now a sizable body of evidence that metastases could develop from circulating tumor cells (CTC) spread in blood before or during surgery. Thus, sensitive and specific detection of CTC in blood is considered as a potentially relevant predictive biomarker for patients with carcinomas. In exchange, the prognostic value of CTC in MPM has not yet been evaluated. Indeed, the main goal for preoperative detection of CTC is to identify patients with high risk of recurrence after surgery, in order to perform more adapted therapeutic strategy. Despite several studies reported about CTC detection, methodological aspects concerning sensitivity, specificity and reproducibility have prevented a clear appraisal of their clinical impact. Thus, the aim of our study is to evaluate the presence and the prognostic value of CTC in MPM by a double approach. In our setting, cytopathological analysis of circulating non hematological cells (CNHC), of epithelial origin, isolated according to their size (ISET, Isolation by Size of Epithelial Tumor cells) along with immunomagnetic selection, identification and enumeration of circulating epithelial cells in peripheral blood (CellSearch method) is considered a promising approach.

Endoscopic thyroidectomy developed rapidly in recent years, and the most popular surgical approach was endoscopic thyroidectomy by bilateral areola approach, but some operative steps was required optimization. One of the most annoying problem was the smog blurring endoscopic lens during surgery. The researcher summarized a set of convenient foot-control exhaust method and carried out this prospective study.
