Long-term results in treating squamous cell carcinoma of the lip, oral cavity, and oropharynx.

At the department of Maxillofacial Surgery of the University of Münster, squamous cell carcinomas of the lip, oral cavity, and oropharynx are treated according to the principle of surgical resection of the tumour and, if indicated, radical neck dissection. In cases of lymph node infiltration, additional radiotherapy is given. The data of 352 patients, treated within 15 years, were evaluated with regard to 5-year minimal survival rate and to the incidence of recurrences in correlation to the tumour stages and form of treatment.
