当教室における口蓋扁桃癌症例の検討

抄録

During the past 10 years, 18 patients with palatine tonsil cancer (all squamous cell carcinomas) were treated in the Department of Otorhinolaryngology of Mie University Hospital. Seven patients (39%) had stage II or III, and 11 (61%) had stage IV carcinoma. The cumulative 5-year survival rate was 50%. All patients were treated with irradiation therapy with or without simultaneous chemotherapy. Salvage operations were performed in 5 patients with residual cancer and radical neck dissection in 10 patients with a cervical mass. Six patients received intra-arterial chemotherapy simultaneously. The original tumors of the 6 patients were controlled by the combination of irradiation and simultaneous intra-arterial chemo-therapy. The 5-year cumulative survival rate was 82% for the patients treated with the combination therapy, and 36% for those who did not receive intra-arterial chemotherapy. We conclude that combination therapy is effective in the treatment of the original tumor of palatine tonsil cancer.
