Summary
Pharmacological treatment alone effectively managed a patient with unresectable adrenal phaeochromocytoma for 11 years. This approach offers a valid alternative for high-risk or unresectable cases of this rare tumor.
Area of Science:
- Endocrinology
- Oncology
- Cardiology
Background:
- Phäeochromocytoma is a rare neuroendocrine tumor originating from chromaffin cells, often in the adrenal medulla.
- It secretes catecholamines, leading to symptoms like hypertension, palpitations, and sweating.
- Surgical resection is the standard treatment, but complications or tumor location can render it unresectable.
Observation:
- A 42-year-old woman presented with severe hypertension, trembling, sweating, visual impairment, headache, and weight loss.
- A right adrenal phaeochromocytoma was diagnosed.
- The tumor was unresectable due to its encirclement of the inferior vena cava.
Findings:
- The patient was treated pharmacologically with phenoxybenzamine and propranolol, later switched to phenoxybenzamine and labetalol.
- She remained normotensive and free of adrenergic hyperactivity symptoms for 11 years.
- Sustained symptom control was achieved without surgical intervention.
Implications:
- Pharmacological management alone is a viable and effective alternative for unresectable phaeochromocytoma.
- This strategy is particularly relevant for patients with high surgical risk or tumors unsuitable for resection.
- Long-term medical therapy can provide a durable solution for managing phaeochromocytoma symptoms and complications.
