 note = {To evaluate primary local control according to tumor size in patients with T2 oropharyngeal carcinoma treated with radical radiation therapy, 38 patients with previously untreated T2 oropharyngeal carcinoma treated with radiation therapy were analyzed. T stage was subdivided into T2a (2.1-3.0 cm) and T2b (3.1-4.0 cm) in this study. Twenty-three patients (T2a: 13, T2b: 10) received external radiation therapy alone, two patients (T2a: 1, T2b: 1) received external radiation plus interstitial brachytherapy, and 13 patients (T2a: 8, T2b: 5) received external radiation plus intra-oral cone radiation. All cases were treated with curative intent. Two-year primary local control rates were 61% for T2a, and 17% for T2b (p< 0.05). These data suggest that tumor size may be a prognostic factor for primary local control in patients with T2 oropharyngeal carcinoma. This study was undertaken using a small number of patients. Therefore further study should be pursued with a greater number of patients., 論文},
