Abstract
A retrospective study of 39 patients treated for sinonasal adenocarcinoma between 1995 and 2010 was performed. Epidemiological, clinical, histological, and therapeutic aspects of this series of patients were analyzed statistically and their impact in terms of overall and disease-free survival established using the Kaplan-Meier method. A search for prognostic factors was made using a log-rank test. The male to female sex ratio was 6.8 to 1. The average age at diagnosis was 65.7 years (range 40.2-85.6 years). An occupational risk factor (wood dust, leather) was found for 19 patients (48.7%). The median patient follow-up was 51.9 months (range 8-180 months). Tumours were classified as T1 in 20.5%, T2 in 25.6%, T3 in 23.1%, and T4 in 30.8% of cases. Disease-free survival rates at 1, 5, and 10 years were 87.9%, 44.8%, and 39.2%, respectively; overall survival rates were 86.1%, 72.2%, and 50.3%, respectively. Overall survival was correlated with tumour status (TNM, American Joint Committee on Cancer) (P=0.004). Surgery followed by radiotherapy improved overall survival (P=0.012) and disease-free survival (P=0.028) when compared to other treatment modalities. When compared to surgery alone, surgery followed by radiotherapy improved disease-free survival regardless of tumour stage (P=0.049).
