No results posted yet for this study

Summary

Pheochromocytoma or paraganglioma are tumors generating hypertension as a symptom. Different biological tests are currently available to diagnose these tumors. However, they all lack specificity since they do not distinguish cases of hypertension without pheochromocytoma or paraganglioma. To improve the diagnostic specificity of these tumors, the investigators are testing a new marker called EM66.

Conditions

  • Pheochromocytoma
  • Paraganglioma
  • Essential Hypertension

Interventions

OTHER

usual follow up with regular EM66 & Cga levels assessment

Patients with pheochromocytoma / paraganglioma will be followed-up as the international standards recommend. Regularly, blood samples will be drawn for the usual assessment of CgA levels and also EM66 (research purpose) levels.

OTHER

plasma EM66 & CgA levels assessment

After inclusion checking to eliminate the presence of pheochromocytoma / paraganglioma, a blood sample will be drawn to assess plasma EM66 and CgA levels.
