[Clinical picture and roentgen therapy of lip carcinomas]

204 patients with lip cancer (squamous cell carcinoma and basal cell carcinoma) were irradiated with soft x-ray and cobalt-radiation respectively after histological examination of the tumor. Available observations were supplied by 190 patients. Distribution according to age and histology, the size of the tumor, as well as the therapeutic results and the recurrence rates are reported. 96,6% of the tumors which showed no metastases at the beginning of the treatment remained recurrence-free after radiation. Early diagnosis, the necessity of treatment and the problem of prophylaxis are emphasized.
