Study of Adrenal Gland Tumors

Adrenal Gland Neoplasm

The adrenal glands, located atop the kidneys, normally produce several types of hormones. Tumors of these glands may or may not secrete hormones. It is not known what causes these tumors or why some secrete hormones and others do not. Some of the tumors are benign and confined to the adrenal gland, and others are malignant (cancerous), and can spread to other parts of the body. This study will investigate how adrenal gland tumors develop, why some secrete steroid hormones and others do not, and why some are benign and others malignant. Patients between 3 and 70 years old with a known or suspected adrenal gland tumor may be eligible for this study. Participants will be hospitalized for 7 to 10 days for various tests and procedures that may include the following: Medical history and physical examination, including body measurements, as appropriate. Children and adolescents will have Tanner staging, including examination of the genitals, to determine the extent of sexual maturity. 24-hour urine collection to measure hormones in the urine. Imaging studies, including magnetic resonance imaging (MRI) of the brain, computed tomography (CT) and other X-ray studies. Blood tests to see if the tumor secretes hormones in response to specific stimuli, including exercise, food, and various hormones. The hormones are given through an intravenous catheter, or IV a thin plastic tube inserted into an arm vein. After the stimulus, blood is drawn through the same IV every 30 minutes for up to 3 hours to measure hormone levels. Based on the results of these tests, some patients may have additional blood tests to check hormone response to special foods, an IV salt solution, or other hormones or drugs given either IV or by mouth (in pill form). Photographs to document the effects on the body of abnormal hormone secretion from the adrenal tumor. Small samples of blood and tumor tissue for research and DNA (genetic) analysis. A discussion of treatment options will be based on the results of tests. If surgery to remove the tumor is recommended, the procedure can be done at NIH under this study protocol. If a malignant tumor is found that cannot be treated surgically, chemotherapy or radiation therapy may be recommended. These options are not offered under this protocol, but may be available under a different NIH study (for example, at the National Cancer Institute). Referrals will be made at the patient s request. Patients who had surgery may be followed at the NIH outpatient clinic for 1 year after surgery. Patients with certain types of tumors may continue to be followed at NIH once a year for up to 5 years. A registry of study participants will be created to keep records and correlate medical histories with tissues kept at NIH. The registry will also be used to inform participants of research studies they may be interested in. No individuals or organizations outside of NIH will have access to the registry....

Rare Cystic Benign Adrenal Incidentalomas

Urologic DiseasesAdrenal Tumor

Benign complex cystic and vascular adrenal tumors comprise a group of lesions characterized by significant rarity. But, their detection is increasing due to improved radiologic imaging techniques. Nevertheless, they are still conflicting with other lesions. the investigators reviewed their experience with complex cystic benign adrenal tumors in adults, review previous reports to determine the appropriate diagnosis and management of these tumors.

Cushing Syndrome

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.

Adrenalectomy for Solitary Adrenal Gland Metastases

Adrenal Gland MetastasesAdrenalectomy

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 tumor remain controversial. Collinson et al reported an increased survival in patients with melanoma. Median survival was 16 months for patients who underwent adrenalectomy compared to 5 months for patients with documented adrenal metastases treated non surgically. The aim of this study is to compare retrospectively in case and control study, performing adrenalectomy, open or laparoscopic, versus supportive treatment for patients with solitary adrenal gland metastases. The investigators will review charts of patients between January 1994 and November 2009 who had adrenal gland metastases. The variables the inevstigators will compare are mortality, morbidity, primary tumour sites, histological cell type, age, tumour size, presence of synchronous metastases, mean time from diagnosis of primary tumor to treatment of adrenal metastases, indication for adrenalectomy, partial versus total adrenalectomy, suspected versus confirmed metastatic disease.

Textbook Outcome in Adrenal Neoplasms

Outcome AssessmentAdrenal Neoplasm

BACKGROUND: Textbook outcome (TO) is a multidimensional quality management tool that uses a set of traditional surgical measures to reflect an "ideal" surgical result for a particular pathology. The aim of the present study is to record the rate of TO in patients undergoing elective surgery for adrenal neoplasms. MATERIAL AND METHODS: Retrospective study of all patients undergoing scheduled adrenal neoplasms surgery at a Spanish university hospital from September January 2010 to December 2022. Emergency surgeries were excluded. The variables included in the definition of TO were: R0 resection, no Clavien-Dindo ≥IIIa complications, no prolonged stay, no readmissions, and no mortality in the first 30 days. The main objective of this study is to analyse the achievement of TO in a series of patients undergoing scheduled adrenal neoplasms resection at the Doctor Balmis General University Hospital in Alicante, Spain. The investigators compare the group of patients who achieve a TO result with the group of patients who do not. A univariable and multivariable analysis will be carry out in order to indentified the variables associated with TO.

18FDG PET Textural Indices in Adrenal Lesion

Adrenal 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 extra-adrenal neoplasia or fortuitously when performing an imaging for another reason. The etiologies are numerous (cortical tumors, medullary tumors, metastatic lesion of a extra-adrenal neoplasia, others). The adrenal masses can be divided into two categories, depending on whether they are hyperfunctional or not. In patients without an oncological history, an adrenal mass discovered is most often a benign adenoma, but requires an endocrine assessment. In patients with known primary cancer, approximately 30% of the adrenal masses are malignant. In all cases, the diagnostic procedure includes an imaging assessment to characterize the lesion and an endocrine assessment. CT scan performed without and after intravenous iodinated contrast agent injection is the first-line examination to assess an adrenal mass. 18F-FDG-PET may be indicated as second-line for characterizing an adrenal mass. Adrenal tumor SUVmax (Standard Uptake Value) and adrenal tumor SUVmax / liver SUVmax ratio are routinely used to determine the malignancy of a lesion. Although very useful for assessing the glucose metabolism of a given lesion, these parameters do not allow assessing the heterogeneity of tumor uptake. The texture analysis corresponds to an analysis of the spatial distribution of FDG uptake, and allows, by the calculation of many indices, an evaluation of the heterogeneity of the tumors. The hypothesis of our study is that the texture parameters could have an additional diagnostic value to improve the performance of conventional quantitative parameters to determine the malignancy of a lesion. The objective of this study is to investigate the diagnostic value of texture indices in a large cohort of patients presenting an adrenal lesion
