ABSTRACT
One hundred-ten patients with squamous cell carcinoma of the maxillary antrum treated at the Department of Therapeutic Radiology, Seoul National University Hospital between Febryary 1979 and September 1986 were retrospectively analyzed. Of these, only 73 patients were eligible for analysis. Forty-one patients were treated with combination of surgery and radiation therapy and 32 patients were treated with radiation therapy alone. The majority of patients had advanced stage (including 47% T4 tumor). Overall 5 year survival rate was 40.4%. In the radiotherapy alone group, 5 year survival rate was 22.1%, and in the combined surgery and radiotherapy group, 5 year survival rate was 65.3%. Of 31 patients who had failures, 22 patients (71.0%) had local failures, 6 patients (19.3%) had regional failures and 3 patients (9.7%) had distant metastasis. Planned combined treatment with surgery followed by radiation therapy is an effective modality for carcinoma of the maxillary antrum.
Key Words: Squamous cell carcinoma, Maxillary antrum, Radiation therapy, 5 year survival rate
