Active clinical trials for "Thyroid Cancer, Papillary"

Primary objective: The 3-years disease-free survival was compared between low-dose group (30 mCi) and high-dose group (100 mCi). Secondary objective: The successful remnant ablation, efficacy, 3-year progression-free survival and safety were compared between low-dose group (30 mCi) and high-dose group (100 mCi). Research Hypothesis：The 3-year disease-free survival of low-dose group (30mci) may not be lower than that of high-dose group (100 mci) in intermediate-risk thyroid papillary carcinoma patients with no structural or functional lesions and stimulated thyroglobulin(ps-Tg)1-20ng/ml. Study design：Single-center, randomized, double-blinded Sample size：254 patients Follow-up：The measurement of serum thyroid function, thyroglobulin/ anti-thyroglobulin antibody(Tg/TgAb) and neck ultrasonography were performed every 3-12 months during the 3 years according to patients' condition, and computerized tomography(CT) scan, positron emission tomography/computed tomography(PET/CT) and diagnostic whole-body 131I scan were added if necessary. Intervention：Randomly allocated into two groups to receive either 30 mCi (low-dose group) or 100 mCi (high-dose group ) radioiodine for post-thyroidectomy ablation therapy. Evaluation index：Primary evaluation index: The 3-year disease-free survival. Secondary evaluation index: Successful remnant ablation, efficacy, the 3-year progression-free survival and safety.

Oxidative stress (OS) could be involved in the progression of papillary thyroid cancer (PTC). Indeed, thyroid differentiation genes are silenced by a mechanism controlled by NOX4-derived OS. On the other hand, TERT contributes to mitochondrial OS protection, which could increase the resistance of cancer cells to therapeutic agents. The investigators aim to address the role of OS and mitochondrial TERT in the progression and therapeutic resistance of PTC. OS and TERT subcellular localization will be investigated in 150 PTCs and correlated to the genetic and expression profile of the tumors and to the clinical and prognostic features of the patients. Mechanisms implicated in TERT mitochondrial migration and the contribution of mitochondrial TERT to tumor progression will be investigated in cancer cell lines and primary cell cultures. This study will allow to identify OS as a marker of therapeutic resistance in PTC and will open new opportunities for the development of novel treatments targeting ROS generation/TERT nuclear export.

Thyroid carcinoma is the common endocrine system malignant neoplasm. At present it has become the malignant neoplasm of fastest growing incidence rate. More than 85% thyroid carcinoma is papillary thyroid carcinoma. Cervical lymph node metastasis is common in papillary thyroid carcinoma patients. This study aim to reveal protein expression differences between papillary thyroid carcinoma with cervical lymph node metastasis and without cervical lymph node metastasis.

This phase II study evaluates F-18 tetrafluoroborate (18F-TFB) PET/CT scan in patients with differentiated thyroid cancer. Diagnostic imaging is necessary for planning treatment, monitoring therapy response, and identifying sites of recurrent or metastatic disease in differentiated thyroid cancer. 18F-TFB PET/CT may accurately detect recurrent and metastatic thyroid cancer lesions, with the potential to provide information for patient management that is better than the current standard of care imaging practices.

A prospective cohort of papillary thyroid carcinoma(PTC), patients who received thermal ablation in our hospital since February 2023 was established as the study object. Preoperative and postoperative demographic data, ultrasonography, other relevant laboratory tests, and thyroid disease-related scales such as fatigue, depression, and stress were collected. The influencing factors of PTC recurrence were analyzed.

The main aim of the study is to evaluate peri-operative surgical characteristics, operation extent, postoperative morbidity, and outcomes in patients undergoing surgery for advanced thyroid cancer in different European centers using the EUROCRINE® database.

Papillary thyroid cancer (PTC) is a common type of differentiated thyroid cancer (DTC) in children and represents the second most common cancer in adolescent females. Recently targeted drugs that block many of the genetic drivers of DTC have become available. While Investigators know that these drugs shrink DTC tumors in many cases, the impact on radioactive iodine (RAI) avidity has not been systematically studied.

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 II trial to study the effectiveness of sorafenib tosylate in treating patients who have locally advanced, metastatic, or locally recurrent thyroid cancer. Sorafenib tosylate may stop the growth of tumor cells by blocking the enzymes necessary for their growth and by stopping blood flow to the tumor.

Background: - Papillary thyroid cancer (PTC) often spreads to lymph nodes in the neck. This can be hard to detect. People often have lymph nodes removed anyway, and researchers want to study if this is a good idea. Objective: - To compare the effectiveness of removing lymph nodes in the neck that show no evidence of cancer along with the thyroid, or removing only the thyroid. Eligibility: - Adults age 18 and older with PTC or thyroid nodules suspicious for PTC, with no evidence that the disease has spread in the body. Design: Participants will be screened with medical history, physical exam, blood tests, scans, and x-rays. Participants will: Answer questions. They may have a tumor biopsy. Have a flexible laryngoscopy. A small tube will pass through the nose to the vocal cords. Group 1: have surgery to remove the thyroid gland only. Lymph nodes in the neck will be removed if the cancer has spread. Group 2: have surgery to remove the thyroid and lymph nodes in the neck. At all post-surgery visits, participants will answer questions and have blood drawn. In addition: 1 day: laryngoscopy. 2 weeks: possible laryngoscopy. 3 months: ultrasound of the thyroid and neck. Discuss whether to try hormone treatment and/or radioactive iodine. Possible diagnostic whole body radioiodine scan (WBS). Participants will swallow a capsule or liquid and lie under a camera. 6 months: ultrasound and maybe laryngoscopy. 1 year: diagnostic WBS and ultrasound. Participants may get thyroid stimulating hormone. Participants will have annual follow-up visits for 10 years. They will have a physical exam, blood drawn, scans, and may complete a questionnaire.
