What Are Pheochromocytoma and Paraganglioma and How Do Families Plan for End of Life?
By CRYSTAL BAI •
The short answer: Pheochromocytomas and paragangliomas (PPGLs) are rare tumors of the adrenal glands and sympathetic nervous system. Malignant PPGLs are slow-growing but often incurable, requiring long-term palliative management and careful end-of-life planning.
Understanding Pheochromocytoma and Paraganglioma
Pheochromocytomas arise in the adrenal medulla; paragangliomas arise in extra-adrenal sympathetic ganglia. Most are benign, but 10–15% are malignant (metastatic). Malignant PPGLs are defined by metastasis — to lymph nodes, bones, liver, or lungs — rather than tumor appearance.
Genetic Associations
A significant proportion of PPGLs are hereditary — associated with mutations in SDHB, SDHD, VHL, RET, NF1, and other genes. Genetic testing and family screening are important components of care.
Prognosis for Malignant PPGLs
Malignant PPGL is generally slow-growing; 5-year survival is approximately 50%. However, SDHB-mutated paragangliomas have higher malignancy rates and more aggressive behavior. Most patients survive years with treatment but ultimately face disease progression.
Hormonal Symptoms and End-of-Life Management
Excess catecholamine secretion causes hypertension, palpitations, sweating, and anxiety — symptoms that must be managed even in palliative settings. Alpha-blockade and blood pressure control remain important comfort measures.
Planning Over a Longer Horizon
Unlike many aggressive cancers, malignant PPGL may allow years of planning. Death doulas and advance care planning can begin early, allowing thorough legacy work and family preparation without the urgency of a compressed timeline.
Frequently Asked Questions
Is pheochromocytoma curable?
Benign pheochromocytoma is curable with surgery. Malignant (metastatic) pheochromocytoma is generally incurable but often slow-growing, with median survival of several years.
What is the treatment for malignant pheochromocytoma?
Treatment includes MIBG therapy, sunitinib, temozolomide-based chemotherapy, and 177Lu-DOTATATE for SSTR-positive tumors. Clinical trials are available at specialized centers.
Can a death doula help with a rare cancer like pheochromocytoma?
Yes — death doulas help families with rare cancers like PPGL navigate the unique challenges of a slow-moving but ultimately terminal illness, including advance care planning and legacy work over a longer timeline.
Where are pheochromocytoma specialists located?
Specialized PPGL programs exist at MD Anderson, NIH, Mayo Clinic, and other NCI-designated cancer centers. The Pheo Para Alliance (pheopara.org) is a patient advocacy resource.
