177Lu-DOTA-EB-TATE in Adult Patients With Metastatic, Radioactive Iodine Non-Responsive Oncocytic (Hurthle-Cell) Thyroid Cancer

Background: Oncocytic (Hurthle cell) thyroid cancer (HTC) is a rare disease with few treatment options. Researchers are developing a radioactive drug that targets a protein that appears in high numbers on HTC cancer cells. Objective: To test a radioactive drug (177LuDOTA-EB-TATE) in people with HTC. Eligibility: People aged 18 years and older with HTC. The HTC must have failed to respond to conventional radioactive treatment; it must also have spread to other parts of the body. Design: Participants will be screened. They will have a physical exam with blood tests. They will have imaging scans and a test of their heart function. 177LuDOTA-EB-TATE is infused into a vein. Participants will receive 4 infusions spaced 8 to 12 weeks apart. They will stay in the hospital for 4 to 10 days after each infusion. During and after each infusion, participants will remain in a lead-lined room until their radiation levels go down; this usually takes about 24 hours. Participants will have 4 to 6 follow-up visits in the weeks after each infusion. Procedures will vary at each visit, but may include more imaging scans; blood and urine tests; and tests of heart function. Participants will have 2 single-photon emission computerized tomography (SPECT) scans. SPECT scans show where the study drug is sticking to tumors or maybe other parts of their body. They will lie on a table while a machine rotates around them. Participants will fill in questionnaires about how their thyroid condition affects their life. Participants will have follow-ups visits for 5 years after their last study treatment.

The Use of 124-I-PET/CT Whole Body and Lesional Dosimetry in Differentiated Thyroid Cancer

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. ...

Prevalence and Predictors of Incidental Thyroid Carcinoma in Patients With Graves' Disease Undergoing Thyroidectomy.

The prevalence of incidental thyroid cancer (ITC) in Graves' Disease (GD) patients undergoing thyroidectomy appears higher than historically believed, potentially exceeding 10% in large contemporary series, although significant variability exists. The presence of nodules is a strong predictor, while the roles of age, sex, and BMI require clarification. Most ITCs are papillary thyroid microcarcinoma(PTMCs) with generally favorable prognoses, but concerns about aggressiveness persist. The purpose of the present study is to accurately evaluate the prevalence of incidental thyroid carcinoma (ITC), including microcarcinomas, in a prospectively enrolled cohort of patients undergoing total thyroidectomy for Graves' disease, utilizing standardized pathological examination protocols and secondary outcomes including predictors and histopathological characteristics.

Mapping Patient Decision-making in Thyroid Cancer

The incidence of thyroid cancer has exploded in the past 5 decades, with a roughly three-fold increase since 1995. Fortunately, many new cases are small, early-stage thyroid cancers. The American Thyroid Association guidelines state that patients with papillary thyroid cancers less than 4 cm can choose either thyroid lobectomy or total thyroidectomy. However, it is unclear why patients will sometimes choose more aggressive treatments that carry additional operative risk when a less aggressive option is available. When investigators examined thyroid specialists' recommendations for thyroid cancer treatment, investigators found significant variation between physicians' risk estimates and their treatment recommendations. This illustrated that patients may receive inconsistent counseling regarding their diagnosis and treatment options from different providers. Worse yet, other studies have shown that patients often do not perceive a choice in their treatment. When patients undergo treatments that do not align with their own priorities and values, they may experience regret and low satisfaction. Decision aids have been shown to help patients feel more educated about their options but have not had an effect on their treatment choice, decision regret, or satisfaction. The aim of this study is to use an ethnographic approach to map the patient decision-making process and develop a Decision Navigation Tool to improve decision outcomes for thyroid cancer patients. An ethnographic approach seeks to understand the social norms, culture, and context that influence these decisions. Investigators will do so in 3 phases: 1) elicit patient decision criteria in selecting initial treatment for thyroid cancer, 2) construction and validation of decision-tree model for initial treatment of thyroid cancer, and 3) pilot randomized controlled trial of a Decision Navigation Tool. To construct the decision model, investigators will recruit a diverse sample of patients with varying age, gender, race/ethnicity, and operative and cancer outcomes. The Decision Navigation Tool will highlight patients' values and priorities and empower them to select a treatment aligned with their preferences. This study will provide important insights into the patient experience of decision-making in thyroid cancer and test the feasibility of a future multi-center large-scale clinical trial of a Decision Navigation Tool to improve decision outcomes.

FAPI PET Imaging - An Exploratory Study

This study is testing a new imaging tracer called \[18F\]FAPI-74 with PET scans. Researchers want to find out how well this tracer shows certain diseases in the body, including several types of cancer and some non-cancer conditions like fibrosis and sarcoidosis. \[18F\]FAPI-74 attaches to a protein found on cells that are active in tumors and areas of scarring or inflammation. This may help doctors see these areas more clearly than with imaging methods used today, especially in diseases where current scans do not work well. People who join this study will get one injection of the tracer into a vein, then have one PET/CT or PET/MR scan. This takes about 2 hours in total. Researchers will compare the results with imaging the participant already had as part of their regular care, such as other PET scans, CT, or MRI. No extra treatment is given, and no other visits are needed. The study will take place at 5 hospitals in Switzerland and plans to include about 770 adults with a confirmed or suspected diagnosis of one of the conditions being studied. The main goal is to see how clearly the tracer shows up on the scan. Researchers will also look at whether this new scan changes how confident doctors feel about a diagnosis, or changes the patient's treatment plan.

Pre-Clinic Visit Online Education for Thyroid Cancer

Through a pilot randomized controlled trial (RCT), we aim to test the feasibility and preliminary impact of two online educational resources among adult patients with thyroid cancer. Each online program can be accessed on the patient's personal device, and will be provided to the patient following a diagnosis of thyroid cancer but before meeting with their surgeon to discuss treatment options. The goal of the resource is to educate patients on the various treatment options for thyroid cancer prior to surgical consultation, so that clinic visit time can be better utilized to discuss patient questions and priorities, and support shared decision making. Clinical (TC-MAX; thyroid cancer related anxiety) and behavioral outcomes (decisional conflict, shared-decision making, treatment decision) will be assessed via online surveys 1-day and 14-days post-visit.

Navigation Intervention for Adolescent and Young Adult Cancer Survivors

The investigators propose to: 1) Adapt an evidence-based cancer-focused patient navigation (PN) program for the Adolescent and Young Adult (AYA) cancer survivor population; and 2) Plan and conduct an effectiveness-implementation trial of this program within Kaiser Permanente Southern California (KPSC). PLEASE NOTE: This study is awarded in two phases. The UG3 phase has been awarded for the first two years; upon successful completion of this phase by meeting pre-defined milestones, the National Cancer Institute (NCI) will provide funding for the second phase of the study (Years 3-6), which will allow our team to conduct a trial to determine the effectiveness of the implementation of the adapted PN program for the AYA cancer survivor population. This application is focused on the initial UG3 phase and will update the protocol for the UH3 trial upon successful completion of the UG3 milestones and receipt of the UH3 award. The primary objectives in the UG3 phase of the study are to adapt and tailor an existing PN program to meet the needs of AYA cancer survivors and the local clinical context via (a) interviews with key stakeholders (patients, clinicians, administrators) and (b) guidance from our AYA Primary Care Survivorship Council. The investigators will conduct a pilot study of the adapted PN program and refine the program to enhance acceptability to patients and clinicians, enhance feasibility and effectiveness, and develop and pilot evaluation tools and methods prior to the start of the UH3 phase of the trial, which will be a larger trial. Objectives will be updated for the UH3 phase once awarded.

Comparison of I-124 PET/CT for the Diagnosis of Thyroid Cancer

Persons diagnosed with thyroid cancer are often treated initially with a thyroidectomy, which is followed by ablation using Iodine-131, a therapy which has been shown to be effective and safe. Imaging of metastatic thyroid cancer has been performed with whole body I-131 and Iodine 123 (I-123) imaging for many decades and use I-123 for staging studies. Iodine 124 (I-124) is a radioisotope of iodine which emits a positron and is imaged using PET (positron emission tomography). This is a single arm prospective trial that evaluates the ability of Iodine-124 (I-124) to detect metastatic thyroid cancer compared to non-interventional, usual care I-123 and I-131 images.

Environmental Factors and Thyroid Cancer

Thyroid cancer incidence has been steadily increasing and has nearly tripled since the 1970's in the US and worldwide. Early detection of small, papillary thyroid cancers using high quality diagnostic imaging explains only about 50% of this increased incidence, suggesting that there is a true increase in the occurrence of thyroid cancer and that changes in the prevalence of environmental risk factors might play a role in thyroid cancer etiology and progression. Yet, the cascade of environmental triggers linked to thyroid cancer remains elusive. 'Exposomics' studies all health relevant chemical exposures that an individual experiences, and leverages metabolomic platforms to estimate the "internal" environment, informing both exogenous exposures and the metabolic products that lead to, or arise from, disease. Besides exposure to ionizing radiation as known modifiable risk factor, epidemiological evidence suggests that exposure to endocrine disrupting chemicals may be a potential thyroid cancer risk factor due to their known effects on thyroid function. However, these studies relied either on exposure questionnaires which are susceptible to recall bias, or used a limited set of targeted biomarkers measured after diagnosis for testing associations with case-control status, and not thyroid cancer prognosis. Further, the molecular basis for observed associations with thyroid cancer remains unclear. To address the overall hypothesis that environmental exposures alter metabolic pathways and therefore affect thyroid cancer prognosis, small amounts of blood will be collected using dried blood microsampler technology (e.g. Mitra® sampling devices), which is minimally invasive and can be used to collect repeated blood measurements at home, without the need for specialized training. These dried blood samples will be used to perform metabolomics experiments, which describe the sum of exogenous exposures, metabolic alterations, and biological response. Additional exposure assessment will be performed using an exposure questionnaire. These results will be associated with thyroid cancer prognosis, e.g. disease-specific survival, disease recurrence, and mutational profiles, thus investigating the role of environmental exposures in the development of more aggressive forms of thyroid cancer.
