Purpose: Evaluating 5-year survival rates of maxillary sinus squamous cell carcinoma treated by different methods.Materials and Methods: From 1997 to 1991, 61 patients of maxillary sinus squamous cell carcinoma were included in our study. There were 11 patients with T3 (18%) disease and 50 patients with T4 (82%) disease. Eighteen patients (29.5%) were treated by radiotherapy alone (RT), 32 patients (52.5%) by combined surgery and radiotherapy (SRT) and 11 patients (18.0%) by combined radiotherapy with intra-arterial 5-FU infusion chemotherapy and antrostomy drainage (CRT).Results: Five-year survival rates were 5.6%, 34.4% and 54.5% in RT, SRT and CRT groups, respectively. Statistical significant difference (p＜0.05) of survival rates was noted. Regional neck nodal metastasis at initial diagnosis carried significant worse survival results than initial NO state (7.1% vs. 36.2%, p=0.0003). Multivariate analysis revealed that treatment methods, sex and N stages significantly influenced the 5-year survival rate.Conclusion: Combined treatment was superior to radiotherapy alone in 5-year survival rates.
