Filter by:This is a 3-arm single center study of 45 patients. These cohorts will include 15 breast patients scheduled to undergo a biopsy, and 15 thyroid patients scheduled to undergo fine needle aspiration, biopsy, or thyroidectomy that consent to undergo an acoustic angiography in conjunction with b-mode ultrasound prior to their scheduled biopsy. Prior to imaging clinical patients, the third arm will include 15 healthy volunteers that will be imaged to optimize imaging parameters.
This is a two part study; part A proposes to collect plasma samples to examine how ctDNA (circulating thyroid DNA) markers correlate with detection of recurrent disease, response to therapy, clinical outcome and pathological data. Part B aims to use tissue obtained from biopsies of primary or recurrent disease to establish cell lines and tumour explants to further investigate the biology of thyroid cancer in the preclinical setting
Investigators intend to evaluate the efficiency of Radiofrequency ablation (RFA) therapy to treat papillary thyroid carcinoma.
The primary objective of this study is to evaluate the outcome of two treatment approaches (immediate surgery or close follow-up) in patients with papillary thyroid microcarcinoma (mPTc) .
Background and Rational (Introduction) Differentiated thyroid carcinoma (DTC) have favorable prognosis. Overall 10-year survival is 93% for papillary carcinoma, and 85% for follicular carcinoma(1). After total thyroidectomy followed by radioiodine remnant ablation, DTC patients are screened for recurrence by measuring the levels of both Tg and TgAb and I-131 whole body scan (WBS) in the follow-up (2) It is reported that elevated TgAb may indicate the recurrent and/or metastatic disease and can be used as an alternative of the tumor marker for DTC . The I-131 WBS has high specificity to detect recurrence (50 to 60% in papillary thyroid carcinoma and 64 to 67% in follicular thyroid carcinoma) (3,4). The I-131WBS showed negative finding in 10 to 15% of patients with detectable serum Tg levels(5). Two factors may account for discrepancy between serum Tg and I-131 WBS . First, the tumor size might be too small to be detected by WBS. Second, the tumor cell may lose the ability to trap radioiodine while still able to secret Tg(6,7). It becomes necessary to investigate with other modalities to identify possible residual disease to initiate the appropriate treatment. (8) Positron emission tomography with 2-deoxy-2-[fluorine-18]fluoro- D-glucose integrated with computed tomography (18F-FDG PET/CT) has emerged as a powerful imaging tool for the detection of various cancers. (9) The combined acquisition of PET and CT has synergistic advantages over PET or CT alone and minimizes their individual limitations. (10) It is a valuable tool for staging and re staging of some tumors and has an important role in the detection of recurrence in asymptomatic patients with rising tumor marker levels and patients with negative or equivocal findings on conventional imaging techniques.(11) Aim of the study The aim of this study was to evaluate the diagnostic accuracy of (PET/CT) in patients with suspected thyroid cancer recurrence or metastasis , with differentiated thyroid cancer (DTC) patients who show elevated serum thyroglobulin (Tg) or antithyroglobulin antibody (TgAb) level with negative radioiodine whole body scan (I-WBS).
This phase II trial studies how well 177Lu-DOTATATE works in treating patients with rare endocrine cancers that have spread from where they started to nearby tissue or lymph nodes (locally advanced), spread to other places in the body (metastatic), or cannot be removed by surgery (unresectable). Radioactive drugs, such as 177Lu-DOTATATE, may carry radiation directly to cancer cells and not harm normal cells. 177Lu-DOTATATE may help to control endocrine cancers compared to standard treatment.
Development of a prospective clinico-biological database allowing the provision of clinical data and corresponding biological materials to the medical and scientific community.
The benefits of prophylactic central neck dissection (pCND) remain controversial in clinically node-negative (cN0) papillary thyroid carcinoma (PTC). This study main goal is to investigate benefits of prophylactic central neck dissection in clinically node-negative papillary thyroid carcinoma.
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 phase II trial studies how well encorafenib and binimetinib given with or without nivolumab works in treating patients with BRAF V600 mutation positive thyroid cancer that has spread to other places in the body (metastatic) and does not respond to radioiodine treatment (refractory). Encorafenib and binimetinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body?s immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. The trial aims to find out if the combination of encorafenib and binimetinib, with and without study nivolumab, is a safe and effective way to treat metastatic radioiodine refractory thyroid cancer.
