RADICAL RADIOTHERAPY WITH STEREOTACTIC IRRADIATION FOR NEUROGENIC MALIGNANT TUMOR OF NASAL CAVITY AND PARANASAL SINUSE

Abstract

The results of the treatment of three cases of neurogenic carcinoma by stereotactic irradiation (STI) using the micro-multileaf collimator (m3) are presented.
Histopathorogical diagnosis was olfactory neuroblastoma in one case and neurogenic malignant tumor in two cases. Two of the cases were treated with stereotactic radio surgery (SRS), and the other one was irradiated with stereotactic radio therapy (SRT) as radical radiotherapy. All cases revealed complete response without recurrence. There was no serious impediment associated with STI. The results suggest that STI therapy is useful for neurogenic malignant tumor of nasal cavity and paranasal sinus. It will be important to estimate the optimum dose of STI to obtain good results without causing impediment.
