Esthesioneuroblastoma Treatment Guidelines

Initial Surgical Management

• Complete surgical resection should be the initial treatment to establish diagnosis, relieve symptoms, and maximize local control 1
• Complete resection (>90% of tumor) significantly improves event-free survival and reduces local recurrence rates 1
• For unresectable tumors, consider neoadjuvant chemotherapy to achieve cytoreduction before attempting surgery 1

Radiation Therapy

• Adjuvant radiation therapy after surgery is standard of care, even when negative margins are achieved 1
• Conventional dose ranges from 45-60 Gy to the primary site 1
• For patients with unresectable disease, definitive radiation therapy alone should be applied 1

Chemotherapy

• Effective agents include cyclophosphamide, vincristine, doxorubicin, and ifosfamide 1

Imaging and Follow-up

• MRI with IV contrast is the preferred imaging modality for diagnosis and follow-up 2, 3
• Somatostatin analog PET/CT or PET/MRI can be helpful in disease extent evaluation and planning of radionuclide therapy 2, 3
• Patients should be followed with neurological assessment and neuroimaging at 3-month intervals 4

Outcomes and Prognosis

• Five-year disease-specific survival can reach up to 90% with appropriate multimodal therapy 1
• Inappropriate grouping of esthesioneuroblastoma with other sinonasal malignancies can lead to incorrect treatment decisions 1
• Esthesioneuroblastoma has a significantly better prognosis than other sinonasal malignancies (5-year survival of ~90% vs 37% for mucosal melanoma) 1
