ABSTRACT

<p><b>OBJECTIVE</b>To study the clinical characters, diagnosis, management and prognosis of patients with adenoid cystic carcinoma in nasal cavity and paranasal sinuses.</p><p><b>METHODS</b>The data were analyzed retrospectively for 88 patients with adenoid cystic carcinoma in nasal cavity and paranasal sinuses, to evaluate the clinical characters, diagnostic and therapeutical aspects and the contribution of every factor influencing the survival. Survival analysis was performed by Kaplan-Meier method, comparison among/between groups was performed using Log-rank test, and multivariate analysis was carried out using Cox proportional hazard model.</p><p><b>RESULTS</b>There were 56 patients in stage III and IV. Most of them received surgical operation combined with radiotherapy. The 5-year, 10-year and 15-year survival rates were 0.640, 0.341 and 0.190 respectively. While there were only 0.833, 0.221 and 0.323, 0.145 in stage III and stage IV lesions respectively. The 5-year and 10-year survival rates of 0.761, 0.415 were obtained in patients who received surgery combined with radiotherapy, 0.750, 0.367 and 0.286, 0.143 respectively in those treated by surgery and by radiotherapy alone.</p><p><b>CONCLUSIONS</b>Advanced adenoid cystic carcinoma should be treated by combined surgical operation and radiotherapy. Stage and treatment approach are the independent factors affecting the prognoses of patients with adenoid cystic carcinoma in nasal cavity and paranasal sinuses.</p>
