Management of advanced squamous cell carcinomas of the maxillary sinus

From 1970 to 1988, 41 cases of advanced maxillary sinus cancers were treated at the University of Kansas Medical Center. Local control for the 37 evaluable patients was achieved in 21 (57%). Local control by radiation therapy alone was achieved in ten of 19 (53%) patients compared with eight of 14 (57%) treated with a combination of surgery and radiation therapy. A dose greater than 6500 cGy correlated with better local control in patients treated with radiation therapy alone. Neck node failure occurred in three of 35 (8%) patients when not electively treated. Neck metastasis either at presentation or at a later stage reduced survival. The overall absolute survival for the entire group at 5 years was 35%. A combination of preoperative radiation therapy and surgery is recommended for patients with advanced-stage maxillary sinus cancer. Radiation therapy is an equally good alternative for those who are not surgical candidates or refuse surgery.
