Surgical resection is the definitive treatment for pheochromocytoma or extra-adrenal paraganglioma that is regionally advanced (e.g., from direct tumor extension into adjacent organs or because of regional lymph node involvement). Data to guide management are limited because regional disease is diagnosed in very few patients who present with pheochromocytoma. However, aggressive surgical resection to remove all existing disease can render patients symptom free. Surgical management of these patients may require en bloc resection of all or part of adjacent organs (e.g., kidney, liver, inferior vena cava) along with extended lymph node dissection. Patients who have undergone complete resection of regional pheochromocytoma require lifelong monitoring for disease recurrence.
