Tumors or cancers of the ADRENAL CORTEX.
The outer layer of the adrenal gland. It is derived from MESODERM and comprised of three zones (outer ZONA GLOMERULOSA, middle ZONA FASCICULATA, and inner ZONA RETICULARIS) with each producing various steroids preferentially, such as ALDOSTERONE; HYDROCORTISONE; DEHYDROEPIANDROSTERONE; and ANDROSTENEDIONE. Adrenal cortex function is regulated by pituitary ADRENOCORTICOTROPIN.

The inner portion of the adrenal gland. Derived from ECTODERM, adrenal medulla consists mainly of CHROMAFFIN CELLS that produces and stores a number of NEUROTRANSMITTERS, mainly adrenaline (EPINEPHRINE) and NOREPINEPHRINE. The activity of the adrenal medulla is regulated by the SYMPATHETIC NERVOUS SYSTEM.

Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.

Semiautonomous, self-reproducing organelles that occur in the cytoplasm of all cells of most, but not all, eukaryotes. Each mitochondrion is surrounded by a double limiting membrane. The inner membrane is highly invaginated, and its projections are called cristae. Mitochondria are the sites of the reactions of oxidative phosphorylation, which result in the formation of ATP. They contain distinctive RIBOSOMES, transfer RNAs (RNA, TRANSFER); AMINO ACYL T RNA SYNTHETASES; and elongation and termination factors. Mitochondria depend upon genes within the nucleus of the cells in which they reside for many essential messenger RNAs (RNA, MESSENGER). Mitochondria are believed to have arisen from aerobic bacteria that established a symbiotic relationship with primitive protoeukaryotes. (King & Stansfield, A Dictionary of Genetics, 4th ed)

Primary aldosteronism with aldosterone-producing adrenal adenoma in a pregnant woman. (1/605)

A 30-year-old pregnant woman complained of muscle weakness at 29 weeks' gestation. She was hypertensive with severe hypokalemia. Lower plasma renin activity and higher aldosterone level than the normal values in pregnancy suggested primary aldosteronism. A cesarean delivery was performed at 31 weeks' gestation because of pulmonary congestion. The neonatal course was uncomplicated. The laparoscopic adrenalectomy for a 2.0-cm right adrenal adenoma resulted in normalizing of her blood pressure and serum potassium level. Although primary aldosteronism is rare, especially during pregnancy, it should be always considered as one of etiologies of hypertension in pregnancy.  (+info)

The expression of inhibin/activin subunits in the human adrenal cortex and its tumours. (2/605)

Inhibins and activins are dimeric proteins of the transforming growth factor-beta superfamily which have been shown to be expressed in the adrenal cortex. Recent studies have suggested a role for these peptides in the pathogenesis and/or function of adrenal tumours. To investigate further their physiological and pathological roles, we have documented immunoreactivity for inhibin alpha, betaA and betaB subunits in normal adult and fetal human adrenals, in hyperplastic adrenals and in adrenal tumours. In the normal and hyperplastic adult gland, diffuse immunopositivity was demonstrated for beta subunits, suggesting that activins (beta beta dimers) can be expressed in all zones. Inhibin alpha was limited to the zona reticularis and the innermost zona fasciculata in the normal gland, extending centripetally into the zona fasciculata in hyperplasia, supporting a role for ACTH in the regulation of expression, and suggesting that expression of inhibins (alpha beta dimers) is restricted. Immunopositivity for all three subunits was seen in both fetal and definitive zones of the fetal cortex, indicating that both inhibins and activins could be expressed in both. Immunopositivity for all three subunits was seen in most adrenocortical tumours. Loss of immunopositivity for inhibin alpha in a subgroup of carcinomas might indicate a role in tumour progression. The greater intensity of staining for inhibin alpha in tumours associated with Cushing's syndrome again suggests a link with cortisol production.  (+info)

Androgen secreting adrenocortical tumours. (3/605)

BACKGROUND: Androgen secreting adrenocortical tumours are rare in children and the determination of their malignant potential can be difficult. OBJECTIVES: To assess the presentation, histology, and clinical behaviour of these tumours. SETTING: Two tertiary referral centres. STUDY DESIGN: Retrospective analysis of children diagnosed with an androgen secreting adrenocortical tumour between 1976 and 1996. PATIENTS: Twenty three girls and seven boys aged 0-14 years. RESULTS: Pubic hair was observed in all children, clitoromegaly or growth of the phallus in 23 children, acceleration of linear growth in 22 children, and advanced bone age (> 1.5 years) in 18 children. Hypersecretion of androgens was detected by assessment of serum androgen concentrations alone in four patients and by 24 hour urine steroid excretion profiles in 22 patients. All 16 tumours measuring < 5 cm in diameter were benign. Of the tumours measuring 5-9 cm, three were malignant and seven were benign, whereas all four tumours > 10 cm were malignant. Histological slides were available for reassessment in 25 children. Although mitoses and necrosis were more characteristic of tumours with malignant behaviour, no exclusive histological features of malignancy were seen. CONCLUSION: Histological criteria for malignancy are not reliable, whereas tumour size is important in assessing malignant potential.  (+info)

The histopathology and ultrastructural features of an adrenocortical oncocytoma are reported. The tumour was discovered incidentally during investigation for hypertension in a 72 year old female. Oncocytic tumours of the adrenal cortex are rare, with only 20 examples described in English language reports. Most have been non-functioning and benign, like the present example. Molecular studies may help assess the significance of oncocytic change in the pathogenesis and behaviour of oncocytic neoplasms.  (+info)

Cloning of a novel kinase (SIK) of the SNF1/AMPK family from high salt diet-treated rat adrenal. (5/605)

PCR-coupled cDNA subtraction hybridization was adapted to identify the genes expressed in the adrenocortical tissues from high salt diet-treated rat. A novel cDNA clone, termed salt-inducible kinase (SIK), encoding a polypeptide (776 amino acids) with significant similarity to protein serine/ threonine kinases in the SNF1/AMPK family was isolated. An in vitro kinase assay demonstrated that SIK protein had autophosphorylation activity. Northern blot revealed that SIK mRNA levels were markedly augmented by ACTH treatment both in rat adrenal glands and in Y1 cells. SIK may play an important role in the regulation of adrenocortical functions in response to high plasma salt and ACTH stimulation.  (+info)

Autocrine role of IGF-II in proliferation of human adrenocortical carcinoma NCI H295R cell line. (6/605)

In adrenocortical tumors, the malignant phenotype is associated with rearrangements (paternal isodisomy) at the 11p15 locus and IGF-II gene overexpression, strongly suggesting that the IGF system is a major determinant of adrenocortical tumor progression. The aim of this study was to validate an in vitro model for investigating the involvement of the IGF system in adrenocortical tumorigenesis. We analyzed the production of IGF mRNA and proteins, IGF-binding proteins (IGFBPs) and IGF receptors by the NCI H295R cell line, which is derived from a human adult adrenocortical carcinoma. H295R cells were shown to proliferate for a long period (26 days) in the absence of serum or any added growth factor. Northern blot analyses showed high IGF-II mRNA contents in H295R cells. The cells secreted large amounts of IGF-II protein (14 ng/10(6) cells per 48 h) although no IGF-I protein was detected. Western ligand blot analyses of conditioned media detected the presence of large amounts of a 34 kDa protein, which was identified as IGFBP-2 by immunoblotting. The presence of high-affinity binding sites for IGF-I and IGF-II on H295R cells was shown by binding experiments using radiolabeled IGFs and confirmed by reverse transcription PCR analyses showing type 1 and type 2 IGF receptors. Proliferation of H295R cells was inhibited by anti-IGF-II antibody (45%) and by anti-type 1 IGF receptor antibody (53%) indicating that IGF-II is an autocrine growth factor for these cells and that its effects are, at least in part, mediated by the type 1 IGF receptor. These findings confirm the involvement of the IGF system in adrenocortical tumors and suggest that the H295R cell line is a suitable in vitro model for studying the molecular mechanisms of adrenocortical tumor proliferation.  (+info)

Evidence for a potential role for HDL as an important source of cholesterol in human adrenocortical tumors via the CLA-1 pathway. (7/605)

CLA-1, a human homologue of rodent scavenger receptor class B1 (SR-B1), has been identified as a receptor for high density lipoprotein (HDL) and is highly expressed in the adrenal gland. Several studies have indicated that HDL might be a source of cholesterol for steroidogenesis in the adrenal gland. In this study, we show that ACTH and its second messenger cAMP stimulated CLA-1 protein expression in a human adrenocortical cell line. We also determined whether CLA-1 plays an important role in steroidogenesis by investigating CLA-1 expression levels in various adrenal tumors including the adenomas of Cushing's and Conn's syndrome. Western blot analysis showed that CLA-1 expression was much higher in the tumors of Cushing's syndrome than in non-tumor lesions of Conn's syndrome and pheochromocytoma. We were able to detect a strong CLA-1 signal in tumors of Conn's syndrome, too. On the other hand, much less CLA-1 expression was detected in Cushing's adenoma adjacent adrenal glands. The immunohistochemical analysis showed that CLA-1 was expressed in the outer region of the adrenal cortex mainly in plasma membranes of the cortical cells but not in the medulla. These findings demonstrated for the first time that ACTH increased CLA-1 protein in cultured human adrenocortical cells, and that cortisol- and aldosterone-secreting adenomas had high CLA-1 proteins in their cell surfaces.  (+info)

A patient with preclinical Cushing's syndrome and excessive DHEA-S secretion having unilateral adrenal carcinoma and contralateral adenoma. (8/605)

We report a case of preclinical Cushing's syndrome in a 54-year-old male associated with bilateral adrenocortical tumours. Physical findings and general laboratory data were unremarkable except for mild hypertension (158/90 mmHg) and impaired glucose tolerance. Endocrinological evaluation revealed the presence of autonomous cortisol secretion including unsuppressible serum cortisol by 8 mg dexamethasone test (11 microg/dl), high serum DHEA-S (3580 ng/ml, normal: 400-3500) and increased urinary 17-KS excretion (31.0-35.8 mg/day, normal: 5.8-21.3). CT scan demonstrated the presence of tumours in both adrenals and bilateral adrenalectomy was subsequently performed. Histological examination of the resected specimens revealed an adrenocortical carcinoma on the right side and an adenoma on the left side with noticeable cortical atrophy in non-neoplastic adrenals. Immunohistochemical study of steroidogenic enzymes demonstrated that all the steroidogenic enzymes involved in cortisol biosynthesis were expressed in both right and left adrenal tumours. Enzymatic activities of 21, 17alpha, 18, 11beta-hydroxylases were detected in both right and left adrenals except for the absence of 11beta-hydroxylase activity in the left adrenal adenoma. Results of in vitro tissue steroidogenesis examined in short-term tissue culture of the specimens revealed no significant differences between carcinoma and adenoma in cortisol production, but the production of adrenal androgens in carcinoma was significantly higher than that in adenoma, which may indicate the importance of evaluating adrenal androgen levels in patients with adrenocortical neoplasms.  (+info)

While laparoscopic removal of small, benign, functioning adrenal tumors is accepted, laparoscopic resection of adrenal tumors that may be adrenal cortical carcinoma (ACC) remains controversial. Methods. The records of all patients with ACC evaluated at a single institution from 1991 through 2004 were reviewed retrospectively. Results. Among 170 patients with ACC, 153 patients underwent open anterior adrenalectomy, 6 underwent laparoscopic adrenalectomy, 1 was treated via an open flank approach, and 10 had no operation. At a median follow-up of 28 months, 115 (86%) of 133 ...

BACKGROUND: CD44 is a cell surface glycoprotein found on many normal cells, mainly lymphoid and epithelial. Normal cells usually express standard CD44 (CD44-S), whereas malignant tumours may express CD44 variant isoforms (CD44-V). CD44 expression has been described for neural crest derivatives. Characterisation of differences in CD44 expression may help in the diagnosis and differentiation of distinct adrenal tumours. AIMS: To examine CD44 expression in different layers of cortical cortex, in adrenal medulla, and in adrenal tumours. METHODS: CD44-S and CD44-V6 expression were studied in 12 cases of adrenal cortical adenoma, 3 of adrenal cortical carcinoma, 10 of pheochromocytoma, and 4 normal adrenal glands. RESULTS: CD44-V6 staining showed cytoplasmic expression in normal adrenal cortex and in cortical adenomas and carcinomas. Pheochromocytomas also showed CD44-V6 expression but in 5 of the 10 cases it was sparse, focal, and sometimes perinuclear. Strong membranous staining for CD44-S was ...
1. The major issue to resolve with the various imaging techniques is the differentiation of benign adrenal adenomas from adrenal cortical carcinoma, since biochemical tests can distinguish an adrenal adenoma from a pheochromocytoma. As Dr. Copeland has noted, approximately half of the adrenal masses in patients with known cancer represent metastasis (1). It is in that group of patients that fine-needle aspiration of the adrenal mass is most useful in excluding metastatic disease if the findings on imaging are equivocal. In the study Dr. Copeland cites to advocate the routine use of delayed enhanced CT (2), 39 of the 40 malignant adrenal incidentalomas were metastatic lesions, while the remaining lesion was a malignant pheochromocytoma. None were adrenal cortical carcinomas. Until we have sufficient data that this procedure regularly distinguishes between primary adrenal adenomas and carcinomas, additional research is needed ...
Treatment:. The main method of adrenal tumor treatment is surgery.. At the first stage of tumor development, when the formation does not exceed 5 cm and there is no metastasis, laparoscopic removal is performed.. If the tumor has reached the second stage of development and has grown more than 5 cm, then the method of removal is determined by doctors based on MRI or CT.. At stage 3 of adrenal cancer, when the tumor affects the lymph nodes, a cavitary surgery is indicated. During removal, the surgeon examines nearby organs and tissues for the presence of metastases.. Adrenal cancer of the 4th stage is usually accompanied by metastatic sprouting in the tissue of the kidneys, liver, etc. Such tumors are not always operable. The possibility of prompt removal is determined by the doctor individually.. As additional treatment, other methods are used. Radiotherapy is actively used in pheochromocytomas.. A patient can get a radioactive isotope injection, which kills cancer cells, reducing the size of the ...

AT-101 is a more potent inhibitor of B cell lymphoma 2 family apoptosis-related proteins than its racemic form, gossypol, which showed preliminary clinical activity in ACC. We thus evaluated the efficacy of AT-101 in patients with advanced ACC. Methods Patients with histologically confirmed metastatic, recurrent, or primarily unresectable ACC were treated with AT-101 (20 mg/day orally, 21 days out of 28-day cycles) ...

Somatic mutations in protein kinase A catalytic α subunit (PRKACA) were found to be causative for 30-40% of cortisol-producing adenomas (CPA) of the adrenal gland, rendering PKA signalling constitutively active. In its resting state, PKA is a stable and inactive heterotetramer, consisting of two catalytic and two regulatory subunits with the latter inhibiting PKA activity. The human genome encodes three different PKA catalytic subunits and four different regulatory subunits that are preferentially expressed in different organs. In normal adrenal glands all regulatory subunits are expressed, while CPA exhibit reduced protein levels of the regulatory subunit IIβ. In this study, we linked for the first time the loss of RIIβ protein levels to the PRKACA mutation status and found the down-regulation of RIIβ to arise post-transcriptionally. We further found the PKA subunit expression pattern of different tumours is also present in the zones of the normal adrenal cortex and demonstrate that the different
Childhood adrenocortical tumors (ACTs) are rare, representing ∼0.2% of all pediatric malignancies and having an incidence of 0.2-0.3 new cases per million per year in the United States, but incidences are remarkably higher in Southern Brazil. At diagnosis, most children show signs and symptoms of virilization, Cushing syndrome, or both. Less than 10% of patients with ACT exhibit no endocrine syndrome at presentation, although some show abnormal concentrations of adrenal cortex hormones. Pediatric ACT is commonly associated with constitutional genetic and/or epigenetic alterations, represented by germline TP53 mutations or chromosome 11p abnormalities ...

Adrenal cortical carcinoma (ACC) has previously only been reported in eight patients with type 1 neurofibromatosis (NF1). There has not been any clear evidence of a causal association between NF1 gene mutations and adrenocortical malignancy development. We report the case of a 49-year-old female, with no family history of endocrinopathy, who was diagnosed with ACC on the background of NF1, due to a novel germline frame shift mutation (c.5452_5453delAT) in exon 37 of the NF1 gene. A left adrenal mass was detected by ultrasound and characterised by contrast computerised tomography (CT) scan. Biochemical tests showed mild hypercortisolism and androgen excess. A 24-h urinary steroid profile and 18flouro deoxy glucose PET suggested ACC. An open adrenalectomy was performed and histology confirmed ACC. This is the first reported case with DNA analysis, which demonstrated the loss of heterozygosity (LOH) at the NF1 locus in the adrenal cancer, supporting the hypothesis of an involvement of the NF1 gene ...
Adrenal cortical carcinoma (ACC) is a rare cancer, with an annual incidence of about 1-2 per million [1]. ACC has a poor prognosis, with a 5-year overall survival rate of less than 40% for all cancers and 10% for metastatic cancers [2]. However, even in metastatic ACC, the prognosis is quite variable, with reported survival ranging from a few months to more than 10 years, suggesting the heterogeneity of these tumors [3]. Tumor, node, metastasis (TNM) staging has been used as a predictor of survival and has been modified to improve its prognostic power; currently, the eighth edition of TNM staging and European Network for the Study of Adrenal Tumors (ENSAT) staging systems are used [4,5,6]. Nevertheless, a significant proportion of patients with localized disease according to TNM staging experience recurrence after surgery (up to 70% within 3 years), which is the only curative treatment to date [2]. Tumor grade, as assessed by mitotic count and proliferation indices such as the Ki-67 index, has ...
This phase III clinical trial is studying how well cisplatin-based chemotherapy and/or surgery works in treating young patients with stage I, stage II, stage III or stage IV adrenocortical cancer. Drugs used in chemotherapy, such as cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more tumor cells. Giving chemotherapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Giving it after surgery may kill any tumor cells that remain after surgery ...

The adrenal glands are the major source in the body of the steroid hormones. In normal physiology, the pituitary hormone ACTH regulates the secretion of glucocorticoids, while the secretion of mineralocorticoids such as aldosterone is controlled by the renin-angiotensin system. In addition to these two classes of steroids, the adrenal gland secretes lesser amounts of intermediate metabolites as well as dehydroepiandrosterone (DHEA) and its sulfated product (DHEAS) and androstenedione, testosterone, estrogen, and estrone. Dysregulated secretion of any of these hormones can be caused by sporadic adrenocortical adenomas or carcinomas, with the development of specific clinical syndromes depending on the identity of the hormones secreted. In at least a subset of cortisol-producing adrenocortical neoplasms, the presence of ectopic or abnormal receptors has been described, resulting in the regulation of cortisol and/or aldosterone by non-physiologic stimuli. The present study will serve as a mechanism ...

An interesting phenomenon consists of adrenal collision tumors. Thus a contiguous adrenal adenoma and metastasis results in the adenoma component displaying a signal loss on opposed-phase MR images and the metastatic component increasing in signal intensity. At times neither a biopsy nor a resected specimen allows adequate evaluation of an adrenocortical tumor if only histologic criteria are employed; immunohistologic staining is often helpful. Nevertheless, even then the true nature of a tumor may not be apparent. For example, CT and US discovered an incidental homogeneous adrenal tumor in a 43-year-old woman; endocrine tests revealed preclinical Cushings syndrome. An adrenalectomy was performed, and histology revealed an adrenocorticaltumor of undetermined nature, 4 months later the patient presented with a metastatic cortisol and androgen-producing adrenocortical carcinoma ...
Adrenocortical tumors consist of benign adenomas and highly malignant carcinomas with a still incompletely understood pathogenesis. A total of 46 adrenocortical tumors (24 adenomas and 22 carcinomas) were investigated aiming to identify novel genes involved in adrenocortical tumorigenesis. High-resolution single nucleotide polymorphism arrays (Affymetrix) were used to detect copy number alterations (CNAs) and copy neutral losses of heterozygosity (cnLOH). Genomic clustering showed good separation between adenomas and carcinomas, with best partition including only chromosome 5, which was highly amplified in 17/22 malignant tumors. The malignant tumors had more relevant genomic aberrations than benign tumors, such as a higher median number of recurrent CNA (2631 vs 94), CNAs ,100 Kb (62.5 vs 7) and CN losses (72.5 vs 5.5), and a higher percentage of samples with cnLOH (91% vs 29%). Within the carcinoma cohort, a precise genetic pattern (i.e. large gains at chr 5, 7, 12, and 19, and losses at chr ...
Purpose: ,p,Adrenal incidentalomas must be differentiated from adrenocortical cancer (ACC).

Another area of interest is the role of GATA factors in the regulation of steroidogenic cell differentiation. Our experimental system takes advantage of the observation that GATA-4 normally is expressed in gonadal but not adrenocortical steroidogenic cells of the adult mouse. Interestingly, certain inbred strains of mice develop sex steroid-producing adrenocortical neoplasms in response to prepubertal gonadectomy. This phenomenon is thought to reflect metaplasia of competent cells in the adrenal gland, which transform into gonadal-like stroma in response to changes in the hormonal milieu, and increased expression of GATA4 is a hallmark of this transformation. To examine the signaling pathways involved in this form of tissue-type switching, we have created new inbred and transgenic models of adrenocortical neoplasia .. ...

Background: Adrenocortical carcinomas (ACCs) are among the most common childhood cancers occurring in infants affected with the Li-Fraumeni and Li- Fraumeni-like (LFS/LFL) syndromes, which are caused by dominant germline mutations in the TP53 gene. In Brazil, a particular mutation, occurring in the tetramerisation domain of the gene, p.R337H, is exceedingly common due to a founder effect and is strongly associated with ACC. In this report, we describe the phenotype and long-term clinical follow-up of a female child diagnosed with ACC and homozygous for the TP53 p.R337H founder mutation. Case presentation: At age 11 months, the patient was diagnosed with a virilising anaplastic adrenal cortical tumour, which was completely excised without disturbing the adrenal capsule. Family history was consistent with an LFL tumour pattern, and genotyping identified the TP53 p.R337H mutation in both alleles in genomic DNA from lymphocytes and fibroblasts. Haplotype analysis confirmed the occurrence of the ...

Adrenocortical carcinoma is a rare malignancy with a poor prognosis and presents with mass effects and less often with signs of hormone excess (approximately 60% of all adrenocortical carcinomas). Hormonally active adrenocortical carcinomas most commonly secrete cortisol while the co-secretion of multiple steroid hormones is rare. We report the case of a 59 year-old woman with a medical history of hyperaldosteronism due to a right adrenal adenoma. During follow up, she showed symptoms of hypercortisolism and hyperandrogenemia and a rapid growth of the adrenal mass. She underwent right adrenalectomy and the histology revealed the presence of an adrenocortical carcinoma. Six months post-operatively being on treatment with mitotane, she was diagnosed of metastatic disease to the liver. She underwent right hepatectomy and was started on systemic chemotherapy, with no signs of tumour recurrence during the following six months. The hormonal status should be carefully investigated in all cases of suspected
Adrenocortical cancer (ACC) is a rare disease that is often difficult to diagnose, and therefore often presents at an advanced stage. Various cytotoxic treatments have been tried with little success. Evaluation of new diagnostic methods and improvement of medical therapies are therefore crucial.. The diagnostic potential of 11C-metomidate positron emission tomography (PET) was evaluated in eleven ACC patients. PET visualized all viable tumors with high tracer uptake, including two lesions that CT failed to detect. Necrotic or fibrotic tumors were PET negative. Medication with adrenal steroid inhibitors and chemotherapy may decrease the tracer uptake.. We performed a phase-II study with streptozocin and o,p-DDD (SO) combination therapy in 40 ACC patients. The SO therapy was found to have impact on the disease-free interval (P = 0.02) as well as on survival (P = 0.01) in patients who received adjuvant therapy after curative resection. Complete or partial response was obtained in 36.4% of patients ...
Adrenocortical Carcinoma, also called adrenal cortical carcinoma, is the formation of cancer in the outer layer (cortex) of an adrenal gland. This is the forum for discussing anything related to this health condition
Adrenocortical carcinoma is a rare entity. However, it is the most common type of cancerous adrenal gland tumor with poor prognosis. Approximately 4 to 12 per 1 million people develop this type of tumor, which begins in the adrenal cortex. Adrenocortical carcinoma can occur at any age. Women tend to be diagnosed slightly more often than men. In most cases, the cause of cancerous adrenal gland tumor remains unknown. However, people with certain hereditary conditions have a higher risk. Adrenocortical carcinoma can be a functional or nonfunctional tumor. If the tumor is functional, it may produce hormones causing symptoms such as high blood pressure, low potassium level, heart palpitations, nervousness, feelings of anxiety or panic attacks, excessive perspiration, diabetes, Cushing syndrome, unexplained weight gain or weight loss, weakness, abdominal stretch marks, excessive hair growth, changes in genitalia, change in libido, etc. If the tumor is nonfunctional, symptoms occur because the tumor ...
Adrenocortical carcinoma is an unusual tumor that tends to be larger than 100 g at diagnosis. Malignant adrenocortical tumors of less than 50 g have been reported rarely. We studied a small adrenocortical carcinoma that weighed 40 g and metastasized 3 1/2 years following bilateral adrenalectomy. The malignancy of adrenocortical tumors is frequently difficult to determine. Two recent studies have proposed histologic criteria for determining the malignancy of adrenal cortical tumors. Since the tumor we studied was initially judged to be benign, we sought to determine whether an extensive evaluation of this tumor using these recent criteria could have identified the tumors potential for metastasizing ...
There are different types of treatment for patients with adrenocortical carcinoma.. Different types of treatments are available for patients with adrenocortical carcinoma. Some treatments are standard (the currently used treatment), and some are being tested in clinical trials. A treatment clinical trial is a research study meant to help improve current treatments or obtain information on new treatments for patients with cancer. When clinical trials show that a new treatment is better than the standard treatment, the new treatment may become the standard treatment. Patients may want to think about taking part in a clinical trial. Some clinical trials are open only to patients who have not started treatment.. Three types of standard treatment are used:. Surgery. Surgery to remove the adrenal gland (adrenalectomy) is often used to treat adrenocortical carcinoma. Sometimes surgery is done to remove the nearby lymph nodes and other tissue where the cancer has spread.. Radiation therapy. Radiation ...

At the time of disease discovery there may be no symptoms (the tumor may be found incidentally on imaging). In other patients there may be symptoms of hormone excess or complaints referable to an abdominal mass. Hormone excess presents clinically as Cushings syndrome, virilization, feminization, or, less frequently, hypertension with hypokalemia. Hormone hypersecretion can be found in as many as 73%-79% of ACC patients, although not all patients have symptoms (2). In one study, amongst 45 ACC patients, routine biochemistry documented hormone excess in 33 (73%) with excess glucocorticoid and adrenal androgen in 12, isolated glucocorticoid in 11, isolated adrenal androgen in 7, and 17β-estradiol excess in combination with glucocorticoid and adrenal androgen excess in two and one, respectively. Steroid profiling revealed predominantly immature, early-stage steroid precursors, and their production most likely a consequence of altered expression of steroidogenic enzymes in variably undifferentiated ...

Adrenocortical cancer is an extremely rare tumor presenting with extensive locoregional spread at the time of diagnosis. Due to the diagnostic difficulties
Endocrine cancer can happen by chance, can be caused by environmental exposures, could be caused by a combination of genetic factors, or can be caused by a mutation in a gene.. Certain types of endocrine cancers are more likely to be genetic than others, such as medullary thyroid cancer or adrenal cortical carcinoma in children. Other times endocrine cancers are caused by other factors. Individuals with genetic syndromes have a mutation (or change) in a gene that causes them to be at increased for breast cancer. These mutations are typically inherited from a either parent and can be passed on to children. People with genetic cancer syndromes may be at risk to develop other types of cancers as well. Learning if you have a cancer syndrome can help you understand your risk to develop cancer, your familys risk to develop cancer, and potentially provide you with ways to reduce your cancer risk. ...
Abnormal expression of membrane receptors has been previously described in benign adrenocortical neoplasms causing Cushings syndrome. In particular, we have observed that, in some adreno corticotropic hormone (ACTH)-independent macronodular adrenal hyperplasia tissues, cortisol secretion is controlled by ectopic serotonin7 (5-HT7) receptors. The objective of the present study was to investigate in vitro the effect of serotonin (5-hydroxy tryptamine; 5-HT) on cortisol and renin production by a left adrenocortical carcinoma removed from a 48-year-old female patient with severe Cushings syndrome and elevated plasma renin levels. Tumor explants were obtained at surgery and processed for immunohistochemistry, in situ hybridization and cell culture studies. 5-HT-like immunoreactivity was observed in mast cells and steroidogenic cells disseminated in the tissue. 5-HT stimulated cortisol release by cultured cells. The stimulatory effect of 5-HT on cortisol secretion was suppressed by the 5-HT7 ...

Aims: Structured multicentre efforts are needed if the prognosis of adrenocortical carcinoma (ACC) is to be improved. Data collection may be enhanced through standardised histopathological reporting using criteria such as the recently published Royal College of Pathologists (UK) minimum dataset (MDS). This study aimed to perform a clinicopathological review of the adult patients treated at the Royal Victoria Infirmary, Newcastle upon Tyne, in the 10 years preceding the MDS.. Methods: Case records were examined for all patients diagnosed with ACC between 1996 and 2006. Pathology was reviewed and compared with the Royal College of Pathologists MDS along with the original reports. A systematic evaluation of Ki-67 immunolabelling was also performed.. Results: Eleven patients with ACC were diagnosed and treated.

With recent progress in understanding the pathogenesis of adrenocortical tumors (ACTs), identification of molecular markers to predict their prognosis has become possible. Transcription factor 21 (TCF21)/podocyte-expressed 1 (POD1) is a transcriptional regulatory protein expressed in mesenchymal cells at sites of epithelial-mesenchymal transition during the development of different systems. Adult carcinomas express less TCF21 than adenomas, in addition, the KEGG pathway analysis has shown that BUB1B, among others genes, is negatively correlated with TCF21 expression. The difference between BUB1B and PTEN-induced putative kinase 1 (PINK1) expression has been described previously to be associated with survival in adult but not in pediatric carcinomas. Here, we analyzed the gene expression of TCF21, BUB1B, PINK1, and NR5A1 in adult and pediatric ACTs. We found a negative correlation between the relative expression levels of TCF21 and BUB1B in adult ACTs, but the relative expression levels of TCF21, ...

They shared their protocol for treating this rare disease with Dr. Park, and she changed Katies chemo regimen to follow the St. Judes teams protocol. Although the most current treatment was given, and the primary tumor was removed after 5 rounds of chemotherapy, the cancer recurred within a few months (in spite of follow-on drug therapy, as well). The thinking about adrenocortical carcinoma is that it is a slow-growing cancer; this was clearly not the case for Katie! Obviously, more needs to be known about pediatric cancer, which is the main reason why Katie wanted her Endowment to fund solid tumor research. Katies preference was that it fund adrenocortical carcinoma research, but since that is such a rare disease, her Endowment funds solid tumor ...

Diagnostic and prognostic value of nucleolar proteins in the regulation of tumor cells proliferation in patients with lung carcinoma and adrenocortical cancer
A 16-year-old girl with a masculinizing adrenal carcinoma treated surgically is presented. Following surgery a full clinical and steroid remission has been achieved, without any adjuvant chemotherapy. In the 7th year after the surgical treatment the patient became pregnant. Pregnancy and labour were uncomplicated. The patient continues in complete remission, and her son has been noted to have normal development at 21 mth of age.

Katies Comforters Guild is listed as one of the guilds that supports cancer research. The guilds connection to cancer research is 1) because Katie died of cancer, 2) our family and friends created the Katie Gerstenberger Endowment for Cancer Research in 2007 and 3) we began our work by sewing quilts for children in the cancer ward at Seattle Childrens Hospital - and weve now expanded to blanket the entire hospital. As you know, Katies endowment is for solid tumor research, to help find a cure for the kind of tumor she had (adrenocortical carcinoma). Since adrenocortical carcinoma is very rare, Katies endowment supports ALL solid tumor research with the income that is generated by the principal in the endowment. At last count, the principal was just over $100,000. ...

MEN-1, which was first described as a clinical and genetic syndrome by Wermer in 1954, is an autosomal dominant cancer syndrome, characterized primarily by multiple neoplasias in the parathyroid glands, endocrine pancreas and anterior pituitary. Other endocrine tumors such as gastrinoma, carcinoid, adrenal cortical tumors and cutaneous tumors (angiofibroma, collagenoma and lipoma) may also occur. The genetic defect responsible for MEN-1 has been mapped to chromosome 11 q 13 . The MEN-1 gene consists of 10 exons which encodes a protein of 610 amino acids. Inactivation of MEN-1 gene mutations in both germline and sporadic tumors supports that MEN-1 is a tumor-suppessor gene. Germline MEN-1 gene mutation is responsible for the majority of MEN-1 syndrome cases. MEN-1 induces combinations of more than twenty various endocrine and non-endocrine tumors. A feasible definition of MEN-1 is a case with two of the three main MEN-1 related endocrine tumors (parathyroid adenomas, entero-pancreatic endocrine ...
