Squamous carcinoma of the nasal cavity and paranasal sinuses

This study retrospectively analyzed 105 patients with squamous carcinoma of the nasal cavity and paranasal sinuses. The primary tumor was located in the maxillary sinus in 65 patients (62 percent), the nasal cavity in 27 (26 percent), the ethmoid sinus in 11 (10 percent), and the sphenoid sinus in 2 (2 percent). Over half of the patients with antral cancer were treated with surgery and radiotherapy, whereas one-third of the remaining patients received combination therapy. Most procedures were radical, including sacrifice of the orbital contents in half of the surgically treated patients. The 5-year determinate cure rate was 45 percent for patients with nasal cavity tumors, 38 percent for those with maxillary sinus lesions, and 13 percent for those with ethmoid tumors. Local recurrence remains a major problem despite aggressive surgery and increased use of adjunctive radiotherapy.
