Filter by:This study will evaluate the clinical response and safety of cone beam computed-tomography guided percutaneous cryoablation in bone metastases from thyroid, adrenal and neuroendocrine tumors in 30 patients.
Background: - Adrenal tumors are a common kind of tumor. Some of these secrete extra cortisol into the body, which can lead to diabetes, obesity, and other diseases. Some people with extra cortisol will show symptoms like bruising and muscle weakness. Others will show no signs. This is called subclinical hypercortisolism. Some of these adrenal tumors become malignant. Researchers want to know the best way to treat people with subclinical hypercortisolism. They want to know if removing the tumor by surgery reduces the long-term effects of the disease. Objectives: - To see if removing an adrenal tumor by surgery improves blood pressure, diabetes, obesity, osteoporosis, or cholesterol, and cancer detection. Eligibility: - Adults 18 and older with an adrenal tumor and high cortisol levels. Design: - Participants will be screened with medical history, blood tests, and a computed tomography (CT) scan. - Participants will have a baseline visit. They will have blood and urine tests and 7 scans. For most scans, a substance is injected through a tube in the arm. Participants will lie still on a table in a machine that takes images. - Participants will have surgery to remove their tumor. Some will have surgery right away. Some will have surgery 6 months later, after 2 follow-up appointments. - Participants will have 4 follow-up visits in the first year after surgery. They will have 2 visits the second year, then yearly visits for 3 years. At each follow-up visit, they will have scans and blood tests.
Background: - Tumors of the adrenal gland are common. Most of them are not cancerous. However, there are no tests that can accurately tell which adrenal tumors are cancerous and which are not. The only way to tell is to remove the tumor with surgery and then examine it. Researchers have been using new methods to study samples of adrenal tissue. These methods may help identify whether the cells are or may become cancerous without an operation. This information will help doctors determine which tumors will need to be removed. Objectives: - To collect adrenal tumor tissue biopsy samples in order to study and evaluate new methods that may help identify cancerous or precancerous cells. Eligibility: - Individuals at least 18 years of age who have an adrenal tumor that may or may not be cancerous. Design: - Participants will be screened with a physical examination, medical history, blood and urine tests, and imaging studies. - Participants will be examined to determine whether they have a specific type of adrenal tumor (pheochromocytoma). - Participants whose tumor does not secrete hormones will have a tumor biopsy to collect tissue for study. - Participants who have a large tumor or one that secretes hormones will have standard surgery to remove the tumor. Tissue will be collected for study. - Researchers will examine the collected tissue. They will try to determine whether the cells are cancerous or may become cancerous. - Participants will be asked to return to the National Institutes of Health Clinical Center every year for about 5 years. During these visits they will have imaging studies, lab tests, and a physical examination.
Incidental findings of adrenal tumours,"incidentalomas", occur in 1-5 % in the general population and 10-25 % of these patients will exhibit biochemical mild hypercortisolism. Although the patients do not have clinical signs of classical Cushing's syndrome, they have an increased risk for hypertension, dyslipidemia, diabetes mellitus, osteoporosis and obesity. The hypothesis of the study is, that surgery of the adrenal adenoma responsible for the increased secretion of cortisol, will in part cure or ameliorate the metabolic syndrome.
Background: - Paclitaxel is a chemotherapy drug that is commonly used to treat different types of cancers. However, cancer tumors can become resistant to paclitaxel, and as a result they will fail to accumulate sufficient concentrations of paclitaxel to kill the cancer cells. Researchers are interested in studying whether tumors have become resistant to paclitaxel, but to do so it must be possible to see how much paclitaxel is absorbed by the tumor cells. - 18F-Fluoropaclitaxel (FPAC) is a form of paclitaxel that has been modified to be slightly radioactive in order to show up on positron emission tomography (PET) scans. By injecting a very small amount (much less that that used to treat tumors) of the radiolabeled drug into the body, researchers hope to use PET scans to evaluate the amount of the drug absorbed by solid tumors. Because FPAC is best used to study tumors located above the diaphragm, all subjects in the study will have tumors near or above the diaphragm. Objectives: - To determine the safety and effectiveness of FPAC as a radiological evaluation chemical. Eligibility: - Individuals at least 18 years of age who have been diagnosed with breast, adrenal, renal, or lung cancer and have a tumor located someone in the body at least 1 centimeter above the diaphragm. Design: - Participants will be screened with a physical exam, blood tests, and imaging studies as directed by the study researchers. - Participants will receive a single dose of FPAC, followed by a series of PET scans. Regular scans will be performed for 3 hours after the dose of FPAC. - Participants will also have a single dose of a more conventional radiotracer, followed by a series of PET scans. The results of the two sets of scans will be compared with information from previous imaging studies of participants' tumors.
To determine objective response rates (RR) by RECIST guideline version 1.1 for all patients treated with this strategy consisting of initial therapy with pertuzumab as a single agent and then addition of erlotinib for those who have stable disease or progressive disease at three months (Simon design).
