Summary
Surgical intervention for early-stage esthesioneuroblastoma (olfactory neuroblastoma) can be effective, but requires diligent follow-up. This case highlights successful management without radiotherapy.
Area of Science:
- Oncology
- Otorhinolaryngology
- Neurosurgery
Background:
- Olfactory neuroblastoma is a rare cancer with high recurrence and mortality rates.
- Current treatment strategies involve surgery, radiotherapy, chemotherapy, or multimodal approaches.
- The optimal treatment modality for esthesioneuroblastoma remains undetermined.
Observation:
- A 46-year-old male presented with chronic sinusitis, leading to the incidental discovery of a 5 mm tumor in the left superior nasal meatus during endoscopic ethmoidectomy.
- Histopathological examination and immunohistochemistry confirmed the diagnosis of esthesioneuroblastoma, staged as Kadish A and Biller T1.
- Post-operative MRI revealed residual pathological tissue in the left ethmoid region.
Findings:
- Subsequent frontosphenoethmoidectomy yielded biopsies negative for tumor cells.
- The patient declined radiotherapy and remained asymptomatic during a 12-month follow-up period.
- Exclusively surgical treatment was effective for this early-stage tumor without frontal skull base infiltration.
Implications:
- Complete surgical resection can be a viable primary treatment for select early-stage esthesioneuroblastomas.
- This approach necessitates rigorous and frequent long-term patient monitoring.
- Further research is needed to establish definitive treatment guidelines for esthesioneuroblastoma.
