Filter by:Papillary thyroid carcinoma (PTC) is the most common thyroid cancer and has a good prognosis.According to the 2015 American thyroid association (ATA) guidelines, no gross extrathyroidal extension and the number of pathological lymph node micrometastases (<0.2cm) ≤5 were defined as the low recurrence risk group. After total thyroidectomy and radioiodine treatment, the probability of disease-free status (irritant Tg<1ng/ml, no evidence of other disease recurrence) is about 78%-91%, and the probability of structural recurrence is about 1%-10%. In recent years, due to the further understanding of PTC, surgeons tend to become more conservative in treatment, such as active observation or reducing the extent of surgery. The indication for lobectomy has been extended to tumors <4cm without extrathyroidal extension and clinical lymph node metastasis. For patients treated with lobectomy, current guidelines recommend that Thyroid Stimulating Hormone (TSH) be controlled at 0.5-2 mU/L, but evidence on the prognostic benefits of this TSH inhibition range is lacking.In recent years, a number of studies have suggested that if postoperative TSH in low-risk patients after lobectomy is acceptable within the reference range, it means that a considerable number of patients have a high probability of not receiving thyroxine replacement therapy after surgery, which can significantly improve their quality of life.A previous retrospective study from our institute showed no significant association between TSH levels after lobectomy and prognosis.The aim of this study was to evaluate the benefits and risks of postoperative TSH levels within the reference range (0.4-5 mU/L) in patients with low-risk papillary thyroid cancer who underwent lobectomy.In order to improve the effect of longer recurrence and death time of PTC, the investigators also performed postoperative thyroglobulin and its antibody for short-term treatment response evaluation.
papillary thyroid carcinoma (PTC) is the most common thyroid cancer and has a good prognosis. Surgery is the primary treatment for PTC, and occult lymph node metastasis is not uncommon (20%-80%).The lymph node metastasis of PTC is mostly along the lymphatic drainage path station by station, and most of the first metastasis is to the central lymph node. According to the 2015 American Thyroid Association recommendation, prophylactic central lymph node dissection is recommended for patients with primary T3-4 or cN1b without central lymph node involvement. However, PTC with primary site T1-2, no external invasion and cN0 could not be dissected by central lymph node.Previous studies have suggested that prophylactic dissection should be performed to improve disease-specific survival, reduce local recurrence, improve recurrence risk and treatment response assessment, and help RAI decision making. Although routine prophylactic central lymph node dissection may detect occult lymph node metastasis, the need for further dissection of the recurrent laryngeal nerve and the parathyroid gland may lead to an increased incidence of complications, while its effect on reducing the risk of recurrence and improving prognosis is unclear, and the impact on long-term outcomes may be small.Previous retrospective studies in our institution have shown that routine central neck dissection does not significantly reduce the risk of recurrence. This study was designed to evaluate the benefits and risks of prophylactic central lymph node dissection in cT1b-T2N0 patients with papillary thyroid carcinoma. In order to ameliorate the effects of relapse and long time of death of PTC, thyroglobulin and its antibodies were also evaluated for short-term treatment response after surgery.
The study will include 50 patients newly diagnosed with low-risk thyroid cancer ranging from 18-80 years of age. After scheduling their surgeon visit, the investigators will enroll patients and measure their intended treatment choice, baseline awareness of the three treatment options, expected outcomes, self-efficacy, and activation. The participants will then be randomized 1:1 and deliver the CQUPLE intervention to the intervention group. The control group will receive usual care, which involves providing no disease or treatment specific information outside the surgeon visit. The study team will repeat all measures prior to the surgical consult and after the surgical consult. The study team will record the patients' actual treatment choice after the consult.
This Phase I clinical trial aims to evaluate the safety, tolerability, pharmacokinetics (PK) profile and preliminary efficacy of intratumoral injection of Carbon Nanoparticle-Loaded Iron [CNSI-Fe(II)] in patients with advanced solid tumors. The study also aims to observe dose-limiting toxicities (DLT) of CNSI-Fe(II) to determine the maximum tolerated dose (MTD) or the highest injectable dose in humans, providing dosing guidelines for future clinical studies. CNSI-Fe(II) shows promise as an innovative tumor therapeutic agent due to its unique properties of ferroptosis. The study primarily focuses on assessing the potential efficacy of CNSI-Fe(II) in patients with advanced solid tumors, particularly in patients with Kras mutation, e.g., pancreatic cancer patients.
The incidence of thyroid cancer has increased rapidly in recent years, especially in women. Early differentiated thyroid cancer has a good prognosis, and surgery is the main treatment. Traditional open surgery would leave a scar on the neck. However, emerging minimally invasive procedures can avoid the scar on the neck, resulting in better aesthetic effect, which would have an impact on the quality of life of patients to a certain degree. This study intend to follow up patients regularly with early differentiated thyroid cancer undergoing different surgery. The quality of life, voice, scar would be assessed by authoritative questionaires or scales. We hope to demonstrate that minimally invasive surgery is better than traditional open surgery in order to provide reliable evidence for clinical practice.
The researchers are doing this study to find out if the combination of avutometinib and defactinib is an effective treatment for RAF dimer-driven radioiodine-refractory differentiated thyroid cancer or anaplastic thyroid cancer. The researchers will also test whether avutometinib and defactinib is a safe treatment that causes few or mild side effects.
The association of radioiodine therapy for the treatment of thyroid cancer with nasolacrimal duct obstruction has been well documented in the medical literature. Prior case reports have documented radioactive iodine detection in the tears of patients following radioiodine therapy. It is possible that radioactive uptake by the cells in the lacrimal sac and nasolacrimal duct lead to inflammation, fibrosis, and obstruction of the tear duct over time. A recent study has shown that the administration of artificial tears decreases the level of detectable radioiodine in the tears of patients undergoing radioiodine therapy for thyroid cancer. The purpose of this study will be to assess whether administering tears after radioactive iodine therapy for thyroid cancer decreases the incidence of nasolacrimal duct obstruction in the two years following radioactive iodine treatment.
An observational cross-sectional case-control study on the postoperative quality of life (5 aspects, general quality of life, thyroid specific quality of life, scar appearance, voice and swallowing functions) of papillary thyroid carcinoma (PTC) patients underwent thyroid lobectomy via different approach, open vs trans-axillary. The patients are recruited in Peking Union Medical College Hospital (PUMCH) from 2020 to 2023 and are evaluated by follow-up with both outpatient visits and questionnaires made up of 9 validated scales.
Phase 1/2 study to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and efficacy of SNS-101, a novel anti VISTA IgG1 monoclonal antibody as monotherapy or in combination with cemiplimab in patients with advanced solid tumors.
Despite use of meticulous surgical techniques and regardless of surgical access via conventional open or endoscopy, postoperative adhesions develop in the vast majority of patients undergoing neck surgery. Such adhesions represent not only adhesion reformation at sites of adhesiolysis, but also de novo adhesion formation at sites of surgical procedures. Improved understanding of the pathophysiology of adhesion development and distinguishing variations in the molecular biologic mechanisms represent future opportunities to improve the reduction of postoperative adhesions. After surgical tissue injury, there were local release of histamine, cytokines, and growth factors that lead to adhesion development. Other than survival or safety issues, cosmetics concerns and quality of life are the motifs after thyroid surgeries currently. Pos-thyroidectomy adhesions include various symptoms such as neck discomfort, neck tightness, skin adhesion to the trachea, skin scarring from adhesive reaction, and vocal cord palsy or impairment of laryngeal vertical movement. Relief of the adhesion through wound massage or anti-adhesion agents could reduce neck discomfort and voice changes.Although oxidized regenerated cellulose (ORC) and hyaluronic acid (HA) appeared to be safe and effective to decrease the incidence of adhesions, to improve adhesion-related neck discomfort, and to prevent skin adhesion to the trachea after neck surgery. The application of antiadhesive barriers after neck surgery is safe but the effect is still uncertain. Thus, we aim to confirm the antiadhesive effect of multiple antiadhesive barriers in thyroid/parathyroid surgery.
