Purpose: We describe our experience with adjuvant radiation therapy in patients who underwent operation for esthesioneuroblastoma. Methods and Materials: Between January 1951 and December 1990, 49 patients with esthesioneuroblastoma received their initial treatment at the Mayo Clinic. There were 27 male and 22 female patients; their ages ranged from 3 to 79 years (median, 54 years). The tumors were Kadish Stage A in 4 patients, Stage B in 13, Stage C in 29, and modified Kadish Stage D in three (cervical nodal or distant metastasis). The tumors were graded according to Hyams' classification. Treatment included gross total resection alone in 22 patients and gross total resection and postoperative adjuvant radiation therapy in 16. The patients treated with adjuvant radiation had a greater proportion of advanced-stage and high-grade tumors. Results: The 5-year actuarial overall survival, disease-free survival, and local control rates were 69.1% + 7.0%, 54.8% + 7.6%, and 65.3% + 7.4%, respectively. The only significant predictor for overall survival, disease-free survival, and local control was Hyams' grade. Local control was improved in patients who received postoperative adjuvant radiation even though this group of patients had more advanced and higher-grade tumors (5-year rate of local control was 85.9% + 9.3%, compared with 72.7% + 9.5% for those who had operation alone, p = 0.26). Conclusion: Adjuvant radiation therapy for esthesioneuroblastoma improves local tumor control, particularly for high-grade and high-stage tumors. We recommend additional treatment with radiation (55.5 Gy) after complete resection of esthesioneuroblastoma.
