ETHMOID AND UPPER NASAL CAVITY CARCINOMA - TREATMENT, RESULTS AND COMPLICATIONS

From 1970 to 1985, 45 patients with carcinoma of the upper nasal cavity and ethmoid sinuses were radically treated. The tumor parameters, treatment strategy, radiotherapy technique and the results of treatment of these patients are retrospectively analysed in this study with particular reference to complete blindness as a major complication. In most cases tumor was removed by meticulous surgical dissection, and thereafter quality-controlled radiation therapy (external therapy: mean dose 65 Gy in about 7 weeks, or external therapy with brachytherapy boost: mean dose 82 Gy in about 10 weeks) was used for this group of patients. The results show 68‰ recurrence-free survival at 5 years, adjusted for intercurrent deaths. Complications of treatment were seen in seven patients (16‰) who developed eye damage with some loss of visual acuity, none however leading per se to complete blindness. It may be concluded that blindness may be avoided to a major extent while treating carcinomas in the nose-ethmoid areas without compromising loco-regional control. © 1990.
