Active clinical trials for "Endocrine Gland Neoplasms"

The OSPREY Patient Registry has been developed to collect and assess the performance and safety of the OncoSil™ device when used within the approved indication of unresectable, locally advanced pancreatic cancer, in combination with gemcitabine-based chemotherapy, within a real-world observational registry. The Registry data will provide both complementary and contemporary information to the existing clinical data across various countries and will form part of the post-market clinical follow-up activities for OncoSil™. Therefore, the Registry will be implemented only in countries with regulatory (commercial) approval for the OncoSil™ device.

Background: - Laboratory investigators who are studying common childhood cancers are interested in developing a tissue repository to collect and store blood, serum, tissue, urine, or tumors of children who have cancer or adults who have common childhood cancers. To develop this repository, additional samples will be collected from children and adults who have been diagnosed with common childhood cancers such as leukemia and tumors of the central nervous system. Objectives: - To collect and store blood, serum, tissue, urine, or tumor samples of children who have cancer or adults who have common childhood cancers. Eligibility: Individuals who have been diagnosed with a common childhood cancer (e.g., leukemia) regardless of patient age. Children, adolescents, and adults who have been diagnosed with a type of cancer more commonly found in adults. Design: Extra blood, serum (the liquid part of blood), tissue, urine, or tumor samples will be collected from participants at a time when sampling is required for medical care or as part of a research study. No additional procedures will be performed for the sole purpose of obtaining additional tumor tissue, aside from what is required for clinical care.

The research is aimed at identifying new predisposition genes for endocrine tumours. Our focus initially is on pituitary adenomas including growth hormone-secreting tumors (somatotrophinomas) and prolactin secreting tumours (prolactinomas), but we wish to extend work to other pituitary tumour cases/families. The recruitment process will be as follows. We will recruit patients from our own Endocrine outpatient clinics and inpatient wards. In addition we will ask colleagues in other Endocrinology Departments (or other specialties such as Clinical Genetics,Pathology, General Medicine ) to identify potentially suitable patients with endocrine & pituitary tumours from their records. We shall focus on patients with good evidence of inheritance of their condition: relatively early onset; or multiple lesions; or other affected family members. Conditions where the predisposing genes have been identified (principally MEN) will be excluded from study. Patients directly contacting us can also enter the study. The Consultant looking after the patient will contact the patient to initially inform him/her of the study. We will then contact the patient (generally by telephone) to discuss the study and what it would entail in terms of information and samples. Subject to agreement in (3), patient will receive 'Information Sheet for patients with pituitary tumour' and 'Consent Form' and will have blood sampling in Consultant's clinic. We will contact additional family members (if appropriate) after an initial approach by the family member already recruited to the study. The additional family members may have developed tumours similar to those of the proband, or may be unaffected individuals who provide useful information for gene identification purposes (for example, spouses may greatly aid the power of gene mapping by linkage. They will receive the "Information Sheet for family members". analysis). 8. Archival tissue will be obtained from HTA licensed tissue banks. This is an established bank whose licence is primarily for diagnosis but can be used for research. 9. We will undertake laboratory work, such as genetic linkage analysis, candidate gene mutation screening and studies of loss of heterozygosity in tumours, to identify the genes predisposing to the condition, such as the AIP gene. In addition we would like to screen other genes related to the chaperon AIP molecule, such as AhR, and other genes currently identified (PDE4A5, survivin and Tom20 protein) or may not been identified. Blood samples for DNA and RNA will coded with unique ID numbers. Pituitary and other endocrine tumour samples will be collected at surgery and kept in liquid nitrogen or -80 C. They will be coded with unique ID numbers. Candidate gene sequencing will be performed in the Barts and the London Medical School Genome Centre. RNA expression studies from blood or adenoma tissue samples will be performed by RT-PCR. Protein expression studies will be performed by Western blotting or immunohistochemistry. The first gene we wish to study causes familial acromegaly, a disease resulting from a pituitary adenoma secreting growth hormone. To establish if the candidate gene is also causing possibly sporadic (not familial) cases of the disease, samples (blood and tissue) will be collected from patients with sporadic disease and will be analysed as above.

Symptom interference is common for survivors of young adult cancer (aged 18-39 at diagnosis) and impacts their abilities to achieve normative life goals (e.g., education, careers, independence, romantic/social relationships) as well as adhere to recommended follow-up care. Assistance with symptom management has been rated by young adult survivors as an important and unmet healthcare need; however, skill-based symptom management interventions have typically been tested among older cancer survivors and have not targeted the unique developmental needs of those diagnosed as young adults. The proposed research advances the health and wellbeing of young adult cancer survivors by creating a developmentally appropriate hybrid in-person/mHealth behavioral symptom management intervention which addresses variables (i.e., symptoms and symptom interference) consistently linked to significant social, economic, and health burden.

Objectives: The aim of the present study is to assess the significance of metabolomics and genetics in diagnosing and survival evaluation for pNET in the periodic follow-up of MEN1 patients. Aim 1: To evaluate the relationship of serum global metabolic profiles with subsequent development of aggressive PNET and evaluate patients survival in a nested case-control study of MEN1 patients who have developed aggressive PNETs (cases) and MEN1 patients who have developed non-aggressive PNETs (controls). Aim 2: Validate the top serum metabolites identified from Aim 1 in MEN1 patients who have developed aggressive PNETs and MEN1 patients who have developed non-aggressive PNETs, using a targeted metabolomics approach. Aim 3: Prospectively identify the potential miRNA biomarkers of serum with miRNA sequencing in MEN1 patients who have developed aggressive PNETs (cases) and MEN1 patients who have developed non-aggressive PNETs (controls). Aim 4: Validate the potential miRNA biomarkers identified from Aim 1 in MEN1 patients who have developed aggressive PNETs and in MEN1 patients who have developed non-aggressive PNETs, using a targeted qRT-PCR approach (in serums), as well as to see the relationship of potential miRNA biomarkers with patients survival.

Multiple Endocrine Neoplasia type I (MEN1) or Wermer syndrome is an autosomal dominant disease that predisposes patients to the development of endocrine tumours, principally parathyroid, pituitary or duodenal-pancreatic tumours. It is due to mutations that abolish the function of the MEN1 gene, which contributes to tumour regulation. It is a rare disease, with an estimated prevalence in the general population of 1/30,000. Penetrance of the disease is late but very high (almost 100% at 50 years of age). The first clinical manifestations usually appear after the age of 30 or 40 years. The three cardinal endocrine characteristics of MEN1 are secreting tumours of the parathyroid, the pituitary gland and the pancreas. Tumours of the adrenal glands, bronchial or thymic endocrine tumours, ependymoma and meningioma of the central nervous system, visceral leiomyomas, and certain cutaneous tumours can also be found as well as these cardinal tumours. The diagnosis of MEN1 is essential to ensure 1) appropriate therapeutic management of the proven endocrine manifestations 2) screening for other endocrine and non-endocrine tumours (lesions), 3) family screening of affected relatives whether they are symptomatic or not 4) the surveillance of thus diagnosed patients. Studies on mortality in MEN1 have shown that the causes of death are mainly due to the disease. The non-diagnosis of MEN1 is a cause of therapeutic failure in the management of the endocrine lesions. For the success of the surgical treatment of an isolated endocrine lesion it is important for patients to be oriented towards a diagnosis of MEN1 as the management is different from that in usual situations. Detection is thus of major importance, as early diagnosis can improve the management. Even though the syndrome was discovered in 1903 by Erdheim and correctly documented in 1954 by Wermer, it was only in the 1970s that we became aware of the variety of clinical forms and attempted to codify its treatment. Nonetheless, published studies are fragmented and concern selected populations of few patients. They only partially answer questions arising in clinical practice concerning the prognosis and optimal management of patients. The natural history of the disease in all of its clinical forms is still poorly understood. Although advances in genetics have helped in the diagnosis of MEN1, some clinical forms are still difficult to associate with the syndrome: atypical forms, forms with hardly any symptoms and no genetic diagnosis (10%). These clinical forms need to be clarified to ensure optimal care. Only a large cohort will make it possible to describe the different forms of this disease and to clarify its prognosis

Background: Parathyroid disorders are very common in the general population and include disorders of parathyroid excess, deficiency, or defects in parathyroid hormone (PTH) signaling. PTH, the main secretory product of parathyroid glands is responsible for regulation of calcium-phosphate homeostasis. Objective: i) To investigate the cause of parathyroid disorders ii) To describe evolution, natural history, and longitudinal trends of parathyroid and related disorders seen in syndromic presentations like multiple endocrine neoplasia, hyperparathyroidism-jaw tumor syndrome Eligibility: People ages 6 months older who have, are at risk of having, or are related to a person with a parathyroid or related disorder. Design: Participants will be screened with a review of their medical records. Participants will be seen, tested, and treated by doctors based on their condition. Their visits may be in person or via telehealth. Participants will complete questionnaires. They will answer questions about their physical, mental, and social health. Participants may give samples such as saliva, blood, urine, or stool. Participants may give cheek cell samples. They will do this using a cheek swab or by spitting into a cup. Adult participants may give a skin biopsy. For this, a small bit of skin is removed with a punch tool. Participants may have medical photos taken. If participants have surgery during the course of their regular care either at the NIH or at a different hospital or doctor s office, researchers will ask for some of the leftover tissue. Participants will be in the study as long as they are being seen by their doctor.

Background: Endocrine neoplasms (tumors) are among the fastest growing tumors in incidence in the United States. Furthermore, it is often difficult to distinguish between benign or malignant tumors in cancers of the thyroid, parathyroid, adrenal gland, and pancreas. More research is needed to improve detection and treatment options for patients who develop these kinds of cancer. Researchers are interested in studying the molecular changes that are involved in endocrine cancer development and growth. To collect a sample of tumor specimens and healthy tissue for further study, researchers are specifically looking for samples from patients who are scheduled for surgery or biopsy on endocrine tumors. Objectives: - To collect samples of precancerous, cancerous, and healthy tissue from individuals who are scheduled for surgery or biopsy of endocrine system tumors. Eligibility: - Individuals who have a tumor in or around their thyroid, parathyroid, adrenal gland, pancreas, or any neuroendocrine tissue, and are scheduled for surgery at the National Institutes of Health Clinical Center. Design: Participants in this study will provide blood and urine samples prior to surgery. During the surgery or biopsy, pieces of the tumor or precancerous growth and pieces of normal tissue near to the tumor will be removed for ongoing and future research. The rest of the tumor or growth will be sent for analysis. After surgery, participants will receive routine care until discharge, and doctors will discuss possible treatment options. If there is an appropriate NIH protocol, participants may choose to be treated at the NIH. After discharge, participants will return to the clinic for a routine postoperative check about 6 weeks following the operation, and then may be followed yearly at the Clinical Center or by phone....

Sudden Cardiac Death is a leading cause of mortality and remains a major public health burden worldwide. Cardiac arrest due to coronary heart disease explains a large proportion of the cases, but if autopsy is not performed the exact underlying cause remains obscure in many adults who face sudden death outside heath care organizations. The investigators aim to find proof that primary aldosteronism is a risk factor for sudden death and to characterize the prevalence of adrenal pathology in sudden death of undetermined cause in a case-control study. In addition, the study aims to characterize the prevalence of other adrenal pathology i.e. silent adenomas, cortisol-producing adenomas and pheochromocytomas in sudden death. The investigators also seek evidence that other endocrine hormone overproduction-causing diseases are more prevalent in persons with sudden death compared with those experiencing traumatic or suicidal death sudden death.
