[Treatment methods for primary cancer of the lower lip].

The long-term results of treatment of primary cancer of a lower lip were studied in 954 patients. It was established that cryodestruction was the most effective method for treatment of I and IIA stage squamous cell keratinizing type cancer of a lower lip irrespective of its clinical form. In tumour spreading to the corner of a mouth, and in IIIA stage tumour, use of radiation methods of treatment as the independent ones (close-focus roentgenotherapy and long-focus gamma-therapy) has proved to be of low effectiveness.
