In the current study FDG (Fluorodeoxyglucose) uptake, FLT uptake (F18-Fluoro-3'-deoxythymidine) and their ratios will be correlated with the risk score results of the Oncotype gene-expression assay in patients with clinically negative nodal disease planned for surgical removal of the tumor.
Tumors are characterized by a great heterogeneity. Characterizing this intra-tumor heterogeneity is a major challenge in oncology to improve the therapeutic management and move towards personalized medicine adapted to each patient. However, intra-tumor heterogeneity remains rarely used for diagnostic purposes The discovery of an adrenal mass can occur in different circumstances. Detection of an adrenal mass can be done in a context of secreting syndrome, in the assessment of an...
Arteriosclerosis is a dynamic inflammatory disorder. Recently, FDG-PET CT is emerging diagnostic tool of non-invasive technique to detect vulnerable atherosclerotic plaque. And there are arising evidence that sRAGE(soluble Receptor for Advanced glycation End Product) is correlated with metabolic risk. So the investigators will investigate association between sRAGE and FDG-PET uptake in large artery in healthy patient.
The purpose of this study is to find out if your adrenal glands are normal or abnormal. This can be determined by whether or not your adrenal gland concentrates more of a labeled building block of adrenal hormone, norcholesterol. This labeled material had been used as an investigative diagnostic tool for imaging adrenal glands for many years with success in our hands. This is a diagnostic procedure. CT, MRI and Ultrasound can determine the size and presence or absence of tumor ...
The management of adrenal crisis is often problematic and the time to adequate treatment is frequently delayed.The aim of the study is to evaluate the management of adrenal emergencies requiring parenteral glucocorticoid treatment by a prospective multicenter study in patients with chronic adrenal insufficiency.
This is a clinical research study using I-131 Iodocholesterol which is an experimental radioactive chemical that when injected into the vein, is picked up in the adrenal glands and permits visualization with gamma imaging devices. These images are used in diagnosing a variety of adrenal abnormalities.Prior to the injection of I-131 Iodocholesterol, the patient will receive perchlorate capsules to block any uptake of I-131 by the thyroid gland if this is deemed important. The pa...
The improvement of conventional imaging techniques has led to an increased detection rate of different adrenal tumors. Since those tumors can belong to a variety of entities the therapeutic consequences also show considerable variation. In order to definitely determine the type of tumor, invasive procedures like CT guided biopsies are often required, which could be avoided by a tumor specific imaging method. The presently available scintigraphic procedures are either time consu...
The adrenal glands are one of the most common organs involved in metastatic disease. Metastases are the second most common type of adrenal mass, second only to adenomas. It is a frequent finding during autopsy with a reported rate as high as 27% in patients with known primary malignancy. Although several studies have found an increased survival in patients who undergo resection of solitary adrenal metastases the indications for adrenalectomy in cases of metastatic adrenal tum...
The purpose of this study is to investigate the pathologic features, complications, and prognostic factors of functioning adrenal adenoma and suggest follow-up algorithms for adrenal incidentaloma.
Evaluation of FDG PET/CT to image immunotherapy response in adult thoracic cancer. Compare pre- and post-treatment primary tumor uptake for FDG-PET/CT and correlate with clinical markers of response. PET/CT tumor metabolic response will also be correlated will to progression-free survival and overall survival.
Giant cell arteritis (GCA) affects large and medium sized vessels. Large vessel-GCA (LV-GCA) affecting aorta and/or its main branches is seen a) together with temporal arteritis (AT-GCA), b) as isolated LV-GCA but also c) with polymyalgia rheumatica. There is a risk of vision loss and cerebral thromboembolic events or great vessel injury in GCA. With delayed or inadequate treatment mortality and morbidity increases. This highlights the need of fast diagnosis and early treatmen...
Repeated hemarthroses in patients with hemophilia may lead to hemophilic arthropathy with marked inflammation and synovial hypertrophy. Power Doppler ultrasonography is a useful tool in hemophilic arthropathy for assessment of disease activity and for monitoring response to treatment. Imaging inflammation with glucose analogue fluorine-18-fluorodeoxyglucose positron emission tomography (18F-FDG PET) is based on that infiltrated granulocytes and tissue macrophages use glucose as...
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.
Patients with adrenal insufficiency are at risk to suffer from life threatening adrenal crisis. The aim of this trial was to reevaluate the frequency of adrenal crisis and risk factors for crisis within a prospective study (six-years follow-up of a former prospective study).
The purpose of this survey is to assess patients with chronic primary or secondary adrenal failure regarding subjective health status, incidence and causes of adrenal crisis, hormone replacement regimens and concomitant endocrine or non endocrine disease.
The purpose of this study is to determine if certain MRI sequences can accurately diagnose adrenal masses of unknown origin.
The study will be conducted in a total of 24 subjects before their 6th birthday, requiring replacement therapy for adrenal insufficiency due to either CAH, primary adrenal failure or hypopituitarism. The study will consist of three consecutive cohorts. Cohort 1 will include 12 subjects aged between 2 and < 6 years. If no safety concerns emerge, then 6 subjects aged 28 days to
Even under established replacement therapy, patients with adrenal insufficiency still suffer from impaired quality of life and experience adrenal crises. Patient education is regarded as important preventive measure. In this study a german-wide standardized education Programme will be evaluated.
The pathogenesis of adrenal tumors is still not fully elucidated and the treatment options for malignant tumors are poor. The current study investigates different aspects of the pathogenesis of adrenal tumors and evaluates different therapeutic options in patients with adrenocortical carcinoma.
Giant cell arteritis (GCA) is a medium to large vessel vasculitis with a predilection for the superficial cranial and intrathoracic arteries. Diagnosing the condition and predicting which patients will develop large vessel complications remains a challenge. There are limitations with temporal artery biopsy, magnetic resonance angiography and ultrasound of temporal arteries and American College of Rheumatology classification criteria. Positron emission tomography (PET) has been...
The objective of this pilot study are (i) to compare response to chemotherapy, time to disease progression and overall survival in patients with pancreatic cancer who will be treated with gemcitabine who demonstrate 18F-FLT uptake to those patients who do not demonstrate 18F-FLT uptake; (ii) to correlate 18F-FLT uptake with hENT1 expression with biopsy samples where available; (iii)to determine the presence or absence of uptake, the relative uptake score (RUS) and tumor to back...
In adrenal tumors, we will examine if there is any correlation between WIESS criteria, prognosis of the tumor, and the different labeling index of the following proliferation biomarkers: MCM3, MCM2, KI-67, P53, NEUROPILIN -1, METALLOTHIONEIN, SEMAPHORIN-3A.
The success of kidney transplantation is hampered by the shortage of organs. One attractive strategy is the use of kidneys from living donors. During the donor operation the kidney artery, kidney vein and ureter have to be interrupted as far as possible from the kidney to have sufficient length for the reconnection of these structures in the transplant operation. An adrenal gland is situated at the upper pole of each kidney. While the arterial supply is accomplished by many sm...
DHEA is an adrenal deriven androgen precourser. The impact of DHEA substitution therapy in adrenal failure is unknown as well as the physiologically effects of DHEA is unknown. Effects of physiologically DHEA substitution is investigated in the model of female adrenal failure.
Cushing Syndrome is an endocrine disorder causing an over production of the hormone cortisol. Cortisol is produced in the adrenal gland as a response to the production of ACTH in the pituitary gland. Between 10% and 20% of patients with hypercortisolism (Cushing Syndrome) have ectopic production of the hormone ACTH. Meaning, the hormone is not being released from the normal site, the pituitary gland. In many cases the ectopic ACTH is being produced by a tumor of the l...
