title: Cancer of the NES complex (Nasal Cavity, Ethmoid, Sphenoid Sinuses): A retrospective review.
abstract: During the period January 1983 to September 1993, 36 patients of Nasal Cavity, Ethmoid / Sphenoid Sinus Cancers were treated at Radiotherapy Department, Medical College. Calcutta. All were treated by irradiation alone. Local control was achieved in about 50% of cases at 6 weeks following completion of treatment. Informations with respect to tumour extension to suspected areas of spread, are very much necessary for accurate Radiotherapy treatment planning and for this reason C.T. Scan imaging is mandatory in pre-treatment work-up of NES Complex cancers. Precision Radiotherapy with utmost care to avoid or lessen Radiation dose to optic nerve, is the most suitable method of treatment for our patients. Stringent and prolonged follow-up necessary to know the treatment outcome as the tumours of NES Complex are characterised by 'delayed recurrence'.
