Abstract
The treatment results of buccal squamous cell carcinoma before and after 2002 were compared. Two hundred forty-five patients with buccal cancer who underwent curative treatment were retrospectively reviewed. The 5-year overall survival rate was 30.0% before 2002 and 53.5% after 2002 (p = .004). On multivariate analysis, T classification, surgical margins, and treatment modality significantly affected overall survival, and N classification and histologic grade had trends to affect it. Invasion depth had a trend to influence locoregional control. For patients with early-stage disease without adverse factors, the locoregional control was similar between surgery alone group and surgery + radiotherapy group. The survival of patients with buccal cancer was improved after 2002, which represented the start of intensity-modulated radiotherapy (IMRT) in our institute. Ipsilateral neck alone irradiation was recommended for T1-2N0-1 and small T3N0 disease, and bilateral neck irradiation could be reserved for advanced disease.
