Résumé
@#ObjectiveTo investigate the factors related with curative effect and prognosis of postoperative radiotherapy for nasal and paranasal sinuses carcinoma.MethodsThe data of 95 patients with nasal and paranasal sinuses carcinoma and received postoperative radiotherapy were reviewed retrospectively. Kaplan-Meier method was used to analyze the survival, Logrank test used to compare the differences between different groups. Multivariate analysis was performed by Cox proportional hazard model.ResultsThe overall 1, 3, 5, 10-year survival rates of 95 patients were 84.2%, 50.5%, 44.2% and 20% respectively. Univariate analysis showed that sex, age, operative modality and tumor dose were not related with survival. Histological and clinical stages were related with survival. Multivariate analysis indicated that histological and clinical stages were independent prognostic factors. The follow-up results showed that visual disturbance, xerostomia, dysaudia were the major side effects.ConclusionPostoperative radiotherapy can improve therapeutic effect in the treatment of nasal and paranasal sinuses carcinoma, and histological and clinical stages are the independent prognostic factors effecting prognosis.
