Abstract
Olfactory neuroblastoma is a rare paranasal sinus malignancy. The traditional approach was craniofacial resection (CFR) and then postoperative radiotherapy until 1998. This review will chart development of a new protocol. This ethics-approved audit evaluated the number of new patients diagnosed with olfactory neuroblastoma, with information relating to patient, disease, and treatment factors noted. There were 24 eligible patients, 16 men, 8 women, 7 Kadish stage B, 17 stage C. The planned treatment was: chemotherapy (cisplatin/etoposide) and determine treatment dependent on response in 6 patients, surgery and radiotherapy in 16 patients, and single-modality treatment only (surgery, radiotherapy 1) in 2 patients. Surgery to radiotherapy occurred in 17 patients. With salvage treatment ultimate local control was 79%. There was a higher local control in those patients who had surgery; abandoning this may carry a higher risk of local failure. The use of response to chemotherapy to determine local treatment remains experimental.
