Introduction: Malignant paraganglioma/pheochromocytoma (MPP) are very rare neuroendocrine tumors with heterogeneous prognostic and no gold-standard treatment. MPP can be associated with germline mutations at SDH-x genes which encode for the succinate dehydrogenase that catalyzes the oxidation of succinate to fumarate. SDH-x mutations lead to inactivation of the enzyme and thus accumulation of succinate.Aim: This project aims to evaluate...

Background: The benefit to risk ratio of mitotane high starting dose regimen in ACC remains unknown.Methods: To evaluate a high starting dose strategy, we performed a single-center, prospective study with three main objectives: 1) to assess the time taken to reach a mitotane plasma level above 14 mg/l (benefit); 2) to evaluate mitotane tolerance (risk) in the first 3 months of treatment and 3) to analyse the correlation using a regression analysis test b...
