The adrenal cancer research network COMETE is federating French research on rare adrenal cancers. COMETE achieved major breakthroughs in the molecular characterization of adrenocortical carcinomas (ACC) and malignant pheochromocytomas/paragangliomas (MPP). Recently, COMETE successfully derived potential biomarkers for prognosis, theranostic and follow-up. Those biomarkers have been retrospectively validated. However the benefit for patients in real life conditions is not yet established. * Main objective : to implement COMETE biomarkers as a routine standard of care for adrenal cancer. * The primary end point is double : * Proportion of biomarkers results provided within 3 months after surgery, * The proportion of informative biomarkers, corresponding to markers passing quality controls and returning a value that is not in the grey zone of the measure. * Secondary objective : to estimate the impact of COMETE biomarkers on patients management. * Secondary endpoints : * Proportion of patients with discrepant clinical and molecular markers ; for discrepancies, proportion of decisions impacted by biomarkers results * Proportion of high risk patients for whom an actionable molecular target was identified * Predictive value (positive and negative) of biomarkers to detect recurrences * Molecular signatures of extraordinary responders to treatments (corresponding to the exceptional RECIST complete response, or to the \>80% tumor reduction sutained for \>6months)
