Filter by:Study rationale High risk patients with differentiated thyroid cancer (DTC) require therapy with 131 I under thyroid stimulating hormone (TSH) stimulation. There are two methods of TSH stimulation endogenous by thyroid hormone withdrawal (THW) leading to hypothyroidism and exogenous by injection of human recombinant TSH (rhTSH Thyrogen). The appropriate 131-I activity utilized for treatment is either based on empiric fixed dosage choice or individually determined activity based on 131 I dosimetric calculations. Although dosimetry utilizing radioactive iodine isotope 131 I enables calculation of maximum safe dose, it does not estimate the tumoricidal activity necessary to destroy the metastatic lesions. The alternative radioactive isotope of iodine -124 I, used for positron emission tomography (PET) imaging, might be used for calculation not only the maximum safe131 I dose, but also to predict the absorbed dose in the metastatic lesions. Study objectives The primary objective of this study is to compare the 124 I -PET/CT lesional and whole body dosimetry in each individual patient with metastatic radioiodine (RAI)-avid thyroid cancer under preparation with rhTSH and THW. The secondary objective is to evaluate the predicted by PET/CT lesional uptake with the early response to therapy. Study design This is a phase 2 pilot prospective cohort study comparing the lesional and whole body dosimetry within each patient undergoing exogenous (rhTSH) and endogenous (THW) TSH stimulation and followed for 5 years. Interventions Each study participant will undergo rhTSH and THW-aided 124 I-PET/CT dosimetric evaluations and will be subsequently treated with THW-aided RAI activity based on dosimetric calculations enabling maximum safe dosage. The patients will be followed in 12+/-3 months intervals for 5 years. Sample size and population This pilot study will include 30 patients with high risk differentiated thyroid cancer presenting with distant and/or loco-regional metastases.
The aim of this study is to make up for the gap by performing a dynamic scan of <Sup>18<Sup>F-FDG PET/CT on newly diagnosed patients with papillary thyroid carcinoma. Pathological and genomic studies are performed. The differences between metastatic central lymph nodes images and tissues are compared at the same time. <Sup>18<Sup>F-FDG PET/CT dynamic imaging is explored in metastatic central lymph nodes with papillary thyroid cancer for the diagnostic value.
Nowadays, 5-step modified Cormack-Lehane scoring (MCL) system is frequently used in the observation of laryngeal structures by direct laryngoscopy. Upper airways with flexible fiberoptic laryngoscopy are routinely evaluated in patients who are predicted to be difficult intubation, who have undergone head or neck surgery previously and who require vocal cords to be evaluated preoperatively. During this examination patients are awake; so the upper airway and the muscles in the base of the mouth have normal tonus and airway reflexes are active. When general anesthesia is applied to the same patients during direct laryngoscopy, the laryngeal view may not be as clear as awake flexible fiberoptic laryngoscopy, since a tonus loss occurs in the muscles after general anesthesia. The aim of the study is to investigate the relationship between preoperative awake flexible fiberoptic laryngoscopy performed by ear- nose- throat (ENT) physicians in patients undergoing total thyroidectomy, and the MCL score during direct laryngoscopy after general anesthesia in the same patients. Thus, investigators would like to determine the reliability of airway evaluation with preoperative awake flexible fiberoptic laryngoscopy in predicting intubation conditions during tracheal intubation under general anesthesia.
The treatment of Papillary Thyroid Microcarcinoma (PTMC) nowadays varies among physicians, surgeons and radiologist. The recently published articles show that the prognosis of PTMC by different means of treatment strategies tends to be good. But multicentered, randomized, parallel and prospective study is rare. RFA is the abbreviation of "Radiofrequency Ablation", which tends to be an alternative strategy except conventional surgery. The investigator aims to confirm whether RFA for treating PTMC braces same effectiveness and prognosis comparing with conventional surgery. Besides, this trial also investigates the safety, economy and psychological quality under different treatments.
An epidemiological, observational, multicenter, cross-sectional, retrospective study on patients ≥ 18 years visited in the oncology services of the participating centers with diagnosis of primary thyroid cancer.
Background: Despite the good prognosis of patients with differentiated thyroid carcinomas (DTC), the diagnosis of cancer, fear of cancer recurrence and its side effects might still bring impacts on patients' quality of life and daily function. Purposes: This is a two-phase study. Phase I will aim to examine the current concerns of patients' physical-, psychological, care needs, and physical and psychological function in DTC patients within one year of diagnosis, and identify factors related to patients' physical and psychological functions. Phase II will be a three-group randomized control trail (RCT). The aims will be develop two intervention programs: Nurse-led Survivorship Care Program (NLSCP, Exp-1) and Information & Communication Technology (ICT) Supported Healthy Active Program (ICT supported HAP, Exp-2), and compare the effects of the two intervention groups and control group of their effects on the variables in the above mentioned four dimensions (physical, psychological, care needs, function) in newly diagnosed DTC patients receiving total thyroidectomy. Methods: Phase I is a cross-sectional survey study and to examine the current status of physical distress (e.g., fatigue, pain), psychological distress (e.g., depression, body-image), care needs, and psychological & physical functions. Phase II is a 6-month three-group RCT with 12 month follow-up of its effects. There will have 5 intervention sections during the first 6 month. Control group will be case manager care only. The NLSCP will receive face-to-face or telephone education by trained nurse. The ICT supported HAP group will receive information or counseling through mobile phone App as the schedule intervention time. For both Exp groups, the first 2 sections of interventions will be all delivered face-to-face for helping them to be familiar with the operation system. Patients in the ICT supported HAP group can raise their concerns or questions through APP and receive intervention through App interactively. The outcomes will be assessed at 5 time points: time before first intervention (baseline assessment), 4-5 week before intervention, 3-, 6-, and 12 months. Expected Outcome: We expect this study can help us better understanding DTC patients' impacts and care needs. The comparison of three groups of intervention will also help us to identify the best model to decrease distress and enhance life function for them.
This study evaluates the combination of lenvatinib with denosumab in bone-predominant metastatic Radioiodine Refractory Differentiated Thyroid Carcinomas. All patients will receive this combination of treatments.
The feasibility and effectiveness of Reversed Tracking Method for the identification and protection of extralaryngeal nerve branches in thyroid surgery were analyzed. Evidence-based medical evidence was used to evaluate the importance of EBSLN recognition and protection in thyroid surgery.
Background: Most patients with thyroid cancer have a long life expectancy, and it has been assumed among health professionals that therefore the quality of life (QOL) is good. Some European studies have shown that the quality of life among thyroid cancers is worse than the general population, and almost as low as other cancer diagnoses, with a worse prognosis and a more burdening treatment. Aim: To examine prospectively the quality of life in participants undergoing diagnostic thyroid surgery and participants undergoing surgery for certain thyroid cancer. By examining both groups we wish to find answers if quality of life is affected, and if so - mostly affected by the diagnosis or the surgery itself. Methods: Participants enroll the study after informed consent, and quality of life will be assessed using quality of life questionnaires EORTC QLQ C30, EORTC THY 47 and EORTC FA12 before surgery, and 6 and 12 months after surgery. This study will form two main groups of participants; with and without thyroid cancer.
This is an observational study of voice outcomes in participants following thyroidectomy or another head and neck surgery that does not involve risk to the larynx other than risks incurred due to intubation alone. These comparative (non-thyroidectomy) surgeries would not be expected to interfere with the primary nerves involved with voice production, so they would help to better understand the effect of intubation alone on voice outcomes.
