Mitotane (o,p’DDD) represents the most effective treatment of adrenocortical carcinoma (ACC). However, molecular mechanisms of mitotane action remain poorly understood. Mitochondrial (mt) impact of mitotane has previously been suggested but not yet fully validated. We investigated functional consequences of mitotane exposure on mitochondrial steroidogenesis, respiratory chain activity and biogenesis, using human adrenocortical secreting H295R and non-secreting SW13 cells....

Background: Hypercalcemia is a well-described paraneoplastic manifestation encountered in a variety of malignancies. However, it is rarely the initial feature of a neuroendocrine tumor.Herein we report a caseof metastatic pancreatic neuroendocrine tumor (NET)presenting with a refractory hypercalcemia and initially misdiagnosed as an adenocarcinoma of the pancreas.Objective: The aim of this case report is to illustratesome of thecom...

Pheochromocytoma and paraganglioma are defined as malignant by the occurence of metastasis in extra paraganglionic sites. The natural evolution of these tumors remains unknown.The aim of our retrospective study was to define the progression-free survival (PFS) of untreated Malignant Pheochromocytoma and Paraganglioma (MPP) at 12 months (12 m-PFS) and to look for prognostic markers of 12 m-PFS. We analyzed clinical parameters of patients followed within 8...
