Q. A 45-year-old male presents to the emergency department with severe abdominal pain and vomiting. On examination, he has hypertension, tachycardia, and abdominal tenderness. CT scan of the abdomen reveals a large mass in the left adrenal gland with evidence of invasion into surrounding structures. Laboratory tests reveal elevated levels of serum cortisol and androgens. A biopsy of the mass confirms the diagnosis of adrenal carcinoma. What is the most appropriate management for this patient?
