[Radical neck dissection for cancer of the oral cavity]

160 radical neck dissections (RND) were performed on 154 patients with cancer of the oral cavity in which cancer of the tongue predominated. The 3-, 5- and 10-year survival rates of these patients were 62.9%, 58.3% and 36.2%, respectively. Those with advanced lesions or positive lymph nodes had poor prognosis. The lymph nodes commonly involved were the submaxillary and the upper deep cervical nodes but "jumping" metastasis to the lower cervical nodes was observed. Elective radical neck dissection is advised for cancer of the tongue. The Survival rate of the patients treated by preoperative irradiation plus RND is higher than that by surgery alone. Proper management of the postoperative complications and regular follow-up of the patients are suggested.
