title: Cranial nerve involvement in nasopharyngeal carcinoma: its prognostic role and response to radiotherapy.
abstract: Between 1975 and 1989, 23 nasopharyngeal carcinoma patients presenting with cranial nerve involvement (CNI) of one or more nerves at the time of diagnosis were treated and followed-up in our department. All patients were irradiated with curative intent, and total doses of 50 to 70 Gy (median 65 Gy) were delivered to the nasopharynx. Cranial nerves VI, III, V, IV, IX, and XII were the most commonly involved nerves. The total response rate of cranial nerves was 74% in a median follow-up time of 2 years, with the highest rate observed in the third and sixth cranial nerves. All complete responses except two were observed in the first month after radiotherapy.
