Treatment Approach for Esthesioneuroblastoma

Initial Assessment and Staging

• Esthesioneuroblastoma is a rare malignancy classified as a primitive neuroectodermal tumor with an incidence of 0.26 per 100,000 person-years 1, 2

Treatment Algorithm

Surgery

• Complete surgical resection should be the initial treatment to establish diagnosis, relieve symptoms, and maximize local control 2, 3
• Complete resection (>90% of tumor) significantly improves event-free survival and reduces local recurrence/progression rates 4

Radiation Therapy

• Adjuvant radiation therapy after surgery is standard of care, even when negative margins are achieved 2, 3
• Conventional dose is 45-60 Gy to the primary site 3
• For patients with unresectable disease, definitive radiation therapy alone should be applied 5

Chemotherapy

• Other effective agents include cyclophosphamide, vincristine, doxorubicin, and ifosfamide 5

Treatment by Stage

• For unresectable tumors, consider neoadjuvant chemotherapy to achieve cytoreduction before attempting surgery 4

Common Pitfalls and Considerations

• Inappropriate grouping of ENB with other sinonasal malignancies can lead to incorrect treatment decisions 6, 7
• ENB has a 5-year disease-specific survival of almost 90%, significantly better than other sinonasal malignancies such as mucosal melanoma (37%) 7
