Lung cancer is a common malignant tumor in clinic. Morbidity and mortality are the first place in cancer, which seriously threaten the health of human beings. Due to the lack of effective and specific screening methods, most patients were found already at an advanced stage, and often combined with bone, brain, liver, adrenal and other parts of the metastasis. Symptoms of patient resulted from the primary tumor, metastatic spread, or paraneoplastic syndrome commonly cause the medical attention. For the syndrome related to the distant metastatic spread as the first manifestation, diagnosis would be a challenge...

The diffuse neuroendocrine system continues to be an enigmatic topic of study in pathology due to its controversial embryologic origins, biology and a variety of tumors engendered. Originally thought to be localized to the classic neuroendocrine organs (pituitary, thyroid, pancreas and adrenal medulla), the neuroendocrine cells are now known to be distributed in every organ system of the body. A number of human diseases have been linked to aberrations in the functioning of the neuroendocrine cells. Neoplasms of the neuroendocrine system can thus occur in myriad primary sites and range in behavior from benign to lethal...

PURPOSE: To evaluate local control and survival after image-guided ablation of adrenal gland metastases. MATERIALS AND METHODS: Image-guided ablations of adrenal metastases measuring < 5 cm performed at 2 academic medical centers between July 2002 and June 2016 were analyzed. There were 51 procedures performed on 46 tumors (mean diameter 2.8 cm ± 1.1; range, 0.7-4.9 cm) in 38 patients (mean age 66 y; range, 41-80 y) with renal cell carcinoma (n = 17 patients; 45%), non-small cell lung cancer (n = 10 patients; 26%), and other primary malignancies (n = 11 patients; 29%)...

BACKGROUND: Medullary thyroid carcinoma (MTC) is a rare disease. Treatment options for recurrent disease are limited. Somatostatin analogues might have a role as anticancer agents agents in MTC, although the evidence is inconclusive. PATIENT FINDINGS: A 64-year old male was diagnosed with MTC in January 2010. Total thyroidectomy with neck dissection (stage IVA, pT2pN1bM0, R1) was performed, followed by adjuvant locoregional radiotherapy. Two years later, the patient developed recurrent metastatic disease evidenced by elevated carcinoembryonic antigen (CEA) and calcitonin levels, and a positive uptake (Octreoscan®) in the right adrenal gland and pancreatic head...

BACKGROUND: The recommended approach to screening for primary aldosteronism (PA) in at-risk populations is to determine the ratio of aldosterone concentration (serum (SAC)/plasma (PAC)) to renin measured in plasma as activity (PRA) or concentration (DRC). However, lack of assay standardisation mandates the need for method-specific decision thresholds and clinical validation in the local population. AIM: The study objective was to establish method-specific aldosterone: renin ratio (ARR) cut-offs for PA in men and women using the IDS-iSYS® assay system (IDS plc)...

Adrenocortical carcinoma (ACC) is a rare endocrine malignancy and has a 5-year survival rate of <35%. ACC cells require cholesterol for steroid hormone production, and this requirement is met via expression on the cell surface of a high level of SRB1, responsible for the uptake of high-density lipoproteins (HDLs), which carry and transport cholesterol in vivo. Here, we describe how this natural lipid carrier function of SRB1 can be utilized to improve the tumor-targeted delivery of a novel natural product derivative - withalongolide A 4,19,27-triacetate (WGA-TA) - which has shown potent antitumor efficacy, but poor aqueous solubility...

Cirrhosis has many complications regardless of the aetiology. Complications include splenomegaly, ascites, hepatic encephalopathy, spontaneous bacterial peritonitis, hepatorenal syndrome and hepatocellular carcinoma and also linked to abnormalities in the endocrine system, including abnormal sex hormone metabolism, thyroid disease, osteoporosis, and, most recently identified, adrenal insufficiency. This prospective cohort study was done to evaluate the impact of adrenocortical insufficiency on clinical parameters in haemodynamically stable cirrhotic patients with ascites and had been performed at the inpatient of GHPD Department, BIRDEM, Dhaka, Bangladesh from April 2011 to March 2012...

The incidence of renal cell carcinoma (RCC) and metastatic adrenal lesions continues to rise and present evolving complexities in terms of management. Technical challenges in treatment delivery are compounded by the setting of an ageing patient population with multiple medical co-morbidities. While the standard of care treatment for both primary RCC and oligometastatic adrenal lesions has typically been surgery, a number of patients may be medically or surgically inoperable, and for whom alternative options require consideration...

BACKGROUND: Hyponatremia can unmask hypopituitarism and secondary adrenal insufficiency. This is important, since the need to screen for steroid deficiency, in patients with hyponatremia is often neglected. PATIENTS AND METHODS: In a retrospective study, twenty-five patients (13f/12m, age 58.9 ± 18.6 years) with hyponatremia (119.7 ± 10.5 mmol/L) were identified among 260 in-patients treated for hypopituitarism in our specialized endocrine unit, over the last decade...

Context: Adrenocortical carcinoma (ACC) is a rare endocrine malignancy with overall poor prognosis. The Ki67 labeling index (LI) has a major prognostic role in localized ACC after complete resection, but its estimates may suffer from considerable intra- and interobserver variability. VAV2 overexpression induced by increased Steroidogenic Factor-1 dosage is an essential factor driving ACC tumor cell invasion. Objective: To assess the prognostic role of VAV2 expression in ACC by investigation of a large cohort of patients...

BACKGROUND: Adrenocortical carcinoma (ACC) is a rare malignancy, with an annual incidence of 1 or 2 cases per million. Biochemical diagnosis is challenging because up to two-thirds of the carcinomas are biochemically silent, resulting from de facto enzyme deficiencies in steroid hormone biosynthesis. Urine steroid profiling by GC-MS is an effective diagnostic test for ACC because of its capacity to detect and quantify the increased metabolites of steroid pathway synthetic intermediates...

PURPOSE: Epithelial-mesenchymal transition (EMT) is a biological dynamic process by which epithelial cells lose their epithelial phenotype and acquire mesenchymal invasive and migratory characteristics. This has been postulated as an essential step during cancer progression and metastasis. Although this is well described in other tumors, the role of EMT in adrenocortical tumors (ACT) has yet to be addressed. METHODS: The aim of this study was to evaluate the expression of EMT markers e-cadherin, vimentin, and fibronectin, along with EMT-transcription factors (EMT-TFs), TWIST1, SIP1, and SNAIL in 24 adrenocortical carcinoma (ACC), 19 adrenocortical adenomas (ACA), 27 childhood-onset adrenocortical tumors (CAT), and 12 normal adrenal glands...

The World Health Organization has recognized Xp11.2 translocation-associated renal cell carcinoma (RCC) as a distinct neoplasm that arises within the kidney. Although many reports of extrarenal carcinoma may be found in the literature, to the best of our knowledge, Xp11 translocation-associated RCC with intact kidneys has not been documented. This report describes a multilobulated right retroperitoneal soft tissue mass (7.9×5.3×12.6 cm) of a 37-year-old man complaining of abdominal pain in the right side...

The diagnosis of low-grade adrenal cortical carcinoma (ACC) confined to the adrenal gland can be challenging. Although there are diagnostic and prognostic molecular tests for ACC, they remain largely unutilized. We examined the diagnostic and prognostic value of altered reticulin framework and the immunoprofile of biomarkers including IGF-2, proteins involved in cell proliferation and mitotic spindle regulation (Ki67, p53, BUB1B, HURP, NEK2), DNA damage repair (PBK, γ-H2AX), telomere regulation (DAX, ATRX), wnt-signaling pathway (beta-catenin) and PI3K signaling pathway (PTEN, phospho-mTOR) in a tissue microarray of 50 adenomas and 43 carcinomas that were characterized for angioinvasion as defined by strict criteria, Weiss score, and mitotic rate-based tumor grade...

Currently, nivolumab (an anti-programmed cell death-1 receptor monoclonal antibody) is available for many types of advanced cancers in Japan. However, there have been few detailed case reports about endocrine-related adverse events of this therapy. Here, we report a patient with metastatic renal cell carcinoma who presented with secondary adrenal insufficiency following nivolumab therapy. Endocrinological assessment by rapid adrenocorticotropic hormone (ACTH) and corticotropin-releasing hormone (CRH) tests revealed that the patient's disorder was a secondary adrenal insufficiency due to pituitary dysfunction...

The usual neoplastic dissease involving suprarenal glands are adrenal metastaes. The majority of suprarenal metastatic disease arise from lung cancer, followed by the stomach and colon cancer, oesophagus, the liver/bile ducts cancer and renal cell carcinoma. Invasive mammary carcinoma usually spreads to the bones, lungs, lymph nodes, liver and the brain. Adrenal gland metastases from invasive no special type carcinoma represents an extremly low rate number of cases. We discuss about a 66 year old patient who presented with a solitary adrenal metastases from triple negative breast invasive carcinoma...

Radioisotope-labeled prostate-specific membrane antigen (PSMA) tracers have been proven accurate for detection of prostate cancer localizations. Uptake of those tracers in other malignant and benign lesions has been reported, including faint accumulation of Ga-PSMA-HBED-CC in adrenal adenoma. A 77-year-old man with prostate carcinoma was scanned with F-DCFPyL, a promising F-labeled PSMA ligand, for prostate-specific antigen progression while on luteinizing hormone-releasing hormone agonist therapy. The PET/CT shows F-DCFPyL uptake in bilateral enlarged adrenals...
