Adrenocortical carcinomas are rare tumors with poor prognosis and limited treatment options. Although widely used as in vitro models to test novel therapeutic strategies, the adrenocortical carcinoma-derived cell lines NCI-H295R and SW-13 have been only partially described genetically. Our aim was to characterize the mutational landscape of these cells to improve their experimental utility and map them to clinical sub-types of adrenocortical carcinoma. Read More

Introduction: The management of large non secreting adrenal tumors (at least 4 cm) is still a matter of debate as it is unclear whether imaging, especially 18F-FDG, can be used to characterize their potential malignancy. Moreover, the risk of new hypersecretion in non-operated tumors is uncertain. Our aim was to better characterize these large adrenal incidentalomas. Read More

Since the first description of laparoscopic adrenalectomy (LA) for pheochromocytoma and Cushing syndrome in 1992, the utilization of and indications for a minimally invasive approach to the adrenal gland have vastly expanded. Although minimally invasive adrenalectomy has been established as the preferred approach for patients with benign tumors of the adrenal gland, minimally invasive adrenalectomy for cancer remains controversial. In this article, the authors review the indications for minimally invasive adrenalectomy for adrenal nodules suspicious for, or established to represent, a primary malignancy or a site of metastatic cancer.

Ectopic adrenocorticotropic hormone (ACTH) production leading to ectopic ACTH syndrome accounts for a small proportion of all Cushing's syndrome (CS) cases. Thymic neuroendocrine tumors are rare neoplasms that may secrete ACTH leading to rapid development of hypercortisolism causing electrolyte and metabolic abnormalities, uncontrolled hypertension and an increased risk for opportunistic infections. We present a unique case of a patient who presented with a mediastinal mass, revealed to be an ACTH-secreting thymic neuroendocrine tumor (NET) causing ectopic CS. Read More

Synthetic progesterone and 5α/β-pregnane-3,20-dione derivatives were evaluated as in vitro and in vivo modulators of multidrug-resistance (MDR) using two P-gp-expressing human cell lines, the non-steroidogenic K562/R7 erythroleukaemia cells and the steroidogenic NCI-H295R adrenocortical carcinoma cells, both resistant to doxorubicin. The maximal effect in both cell lines was observed for 7α-O-benzoyloxy,11α(R)-O-tetrahydropyranyloxy-5β-pregnane-3,20-dione 4. This modulator co-injected with doxorubicin significantly decreased the tumour size and increased the survival time of immunodeficient mice xenografted with NCI-H295R or K562/R7 cells. Read More

There is a growing belief that depression was positively associated with the progression of liver cancer. However, the driving molecular events behind the depression in liver cancer are poorly understood and need to be elucidated. Since hyperactivity of the hypothalamic-pituitary-adrenal (HPA) axis during depression leads to the excessive release of glucocorticoids (GCs), which suppress the activity of NK cells, we hypothesized that high levels of GCs during depression may inhibit function of tumor infiltrating NK cells during the progress of the liver cancer.

This article proposes a consensus nomenclature for fat-containing renal and adrenal masses at MRI to reduce variability, improve understanding, and enhance communication when describing imaging findings. The MRI appearance of "macroscopic fat" occurs due to a sufficient number of aggregated adipocytes and results in one or more of: 1) intratumoral signal intensity (SI) loss using fat-suppression techniques, or 2) chemical shift artifact of the second kind causing linear or curvilinear India-ink (etching) artifact within or at the periphery of a mass at macroscopic fat-water interfaces. "Macroscopic fat" is most commonly observed in adrenal myelolipoma and renal angiomyolipoma (AML) and only rarely encountered in other adrenal cortical tumors and renal cell carcinomas (RCC).

Background: Defects in the type and degree of cellular glycosylation impact oncogenesis on multiple levels. Although the type of glycosylation is determined by protein sequence encoded by the genome, the extent and modifications of glycosylation depends on the activity of biosynthetic enzymes and recent data suggests that the glycome is also subject to epigenetic regulation. This study focuses on the ability of HDAC inhibition to alter glycosylation and to lead to pro-oncogenic alterations in the glycome as assessed by metastatic potential and chemoresistance. Read More
