Treatment outcome of nasal and paranasal sinus carcinoma.

ABSTRACT

PURPOSE: Most authors recommend aggressive management for sinonasal carcinoma treatment. In an attempt to determine the optimal treatment, we assessed the treatment results of our patients with nasal cavity and paranasal sinus carcinoma. MATERIALS AND METHODS: From January 1980 to December 2001, 40 patients with malignant tumours of the nasal cavity and the paranasal sinuses were treated. The median follow-up was 6 years. Thirty-two patients had tumours originating from the maxillary sinus. Thirteen patients had T1-T2 (32.5%) tumours and 27 patients had T3-T4 (67.5%) tumours. The treatment method was surgery plus radiotherapy in 24 patients (60%) and radiotherapy alone in 16 patients (40%). RESULTS: The 5-year overall survival rate was 61%, whereas it was 65% for T1-T2 disease and 56% for T3-T4 disease. The 5-year local control rate was 58%, whereas it was 75% and 50% (p = .219) for T1-T2 and T3-T4 disease, respectively. In multivariate analysis; localization (p = .016), adjuvant radiotherapy (p = .040), local control (p = .05), and gender (p = .013 for female) were statistically significant factors. CONCLUSION: The prognosis for patients with tumours of the sinonasal area is dependent on localization, tumour stage, and treatment modality. Because the most common site of treatment failure is the primary site, efforts to maximize local control should be undertaken.
