Filter by:Malignant pheochromocytoma/paraganglioma (MPP) and adrenocortical carcinoma (ACC) are two rare cancer entities with a very unfavorable prognosis. The knowledge on these rare cancers improved thanks to the French COMETE network originally based on two clinical centers (HEGP and Cochin) well organized for clinical and biological samples collection. Over the last 10 years, the COMETE key partners deciphered molecular mechanisms of tumorigenesis and oncogenesis of these tumors and identified molecular signatures discriminating between benign and malignant cancers by integrated genomic approaches. This strategy was highly successful in delivering new diagnostic applications of genomics technologies that now appear as potentially suitable for rapid implementation in routine clinical care. The main objective of COMETE-TACTIC is to provide an easy-to-use "identity card" of the adrenal tumors that will allow a personalized "à la carte" management of the patient and, when indicated, to the indication of the most accurate molecular targeted therapy. We hypothesize that the improvement of MPP and ACC diagnosis and of the therapeutic options proposed to affected patients will require, 1. the transfer to routine practice and the prospective validation of the novel diagnostic and predictive biomarkers issued from recent discoveries (genetics, genomics, histological biomarkers); 2. the implementation of the translational research projects based on the COMETE collection to identify circulating diagnostic, prognostic and therapeutic genetic and metabolic biomarkers that could be used as non-invasive "liquid biopsies".
Patients with tumors in both adrenal glands and slightly elevated cortisol (subclinical Cushings syndrome) are offered to go through an adrenal venous sampling to try to quantify if the overproduction of cortisol is from one adrenal, or from both sides. If it is one-sided, the investigators offer the patient operation.
The purpose of this study is to compare EUS-B-FNA (using the EBUS scope)with EUS-FNA for left adrenal gland analysis in lung cancer patients.
The general objective is to evaluate the consequences of surgical removal of SCSI on hypertension and cardiovascular risk factors in order to determine on an evidence-based basis if surgical excision of SCSI is preferable to an intensive medical regimen in patients with hypertension.
Standard diagnostic work-up for adrenal incidentalomas (AI) consists of periodical biochemical analysis and CT-scanning in case the initial work-up does not demonstrate the presence of hormonal hypersecretion or adrenocortical carcinoma (ACC), respectively. The overall aim of this study is to improve the cost-effectiveness of the diagnostic strategy for AI. Cost-effectiveness of urine steroid profiling (USP) will be compared to the standard diagnostic strategy of repeated CT-imaging.
Adrenal masses are highly prevalent and detected with high frequency by conventional imaging. Conventional imaging often fails to rule out a malignant lesion. Accordingly, most hormonally inactive adrenal masses removed by surgery are benign adenomas for which surgical removal is unnecessary and poses an avoidable risk to the patients. We hypothesize that the combination of FDG-PET and 123I-Iodometomidate imaging has the potential to noninvasively identify benign adrenocortical adenomas with high accuracy, thereby avoiding unnecessary surgery. Uptake of 123I-Iodometomidate by the adrenal mass demonstrates the presence of CYP 11B enzymes which specifically bind metomidate with high avidity establishing the adrenocortical origin of the lesion, while low uptake of FDG-PET in an adrenocortical lesion establishes its benign nature and excludes the presence of adrenocortical cancer (ACC). The proposed trial will assess the sensitivity, specificity, positive and negative predictive value of the combined imaging for the diagnosis of adrenocortical adenoma. A secondary focus is on the performance of the combined test for differentiating ACC from non-ACC lesions. We expect that the results of our trial will help to greatly reduce the need for surgery in hormonally inactive adrenal masses.
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.
Laparoscopic adrenalectomy has become the gold standard operation for non-malignant adrenal tumors replacing open adrenalectomy. The most popular lateral transperitoneal laparoscopic adrenalectomy (LTLA) approach has been recently challenged by an increasing popularity of the posterior retroperitoneoscopic adrenalectomy (PRA) approach which is believed by many surgeons as an easy to learn, reproducible and beneficial for patients. However, this belief is not evidence-based, so far. The aim of this study is to clarify if PRA is superior to the LTLA as minimally invasive approach to small and benign adrenal tumors.
This first-in-human study is designed to establish the safety and tolerability of ATR-101 in patients with advanced adrenocortical carcinoma whose tumor has progressed on standard therapy. Information will also be collected to determine how long ATR-101 stays in the blood, and if any effect on tumor progression is seen. Biomarkers (blood and urine tests) will determine if any effects on production of steroid hormones (cortisol, aldosterone, estrogen and testosterone) are seen.
The ACRIN 7151 trial will use medical records abstraction data from participants with extracolonic findings (ECFs) reported from the ACRIN 6664 National CT Colonography Trial to: 1) measure incidence of diagnostic imaging, hospitalization, and interventional procedures associated with ECFs reported on computed tomography colonography (CTC), delineated by type of ECF; 2) determine potential predictors of follow-up diagnostic imaging, hospitalization, and interventional procedures, delineated by type of ECF; and 3) evaluate the clinical/pathologic diagnoses associated with indeterminate but potentially significant ECFs. These data can be used to incorporate ECFs into existing models on the cost-effectiveness of CTC in colorectal cancer screening and can potentially be used to develop guidelines for the reporting and management of ECFs.
