Carcinoma of the lip. A retrospective study of 70 patients.

From 1966 to 1978, 70 patients with carcinoma of the lip were treated at the Division of Plastic Surgery, University Central Hospital, Helsinki. The lip tumour was a squamous cell carcinoma in 64 patients, and a basal cell carcinoma in 6 patients. Of these 70 patients, 24 had radiotherapy as the primary mode of therapy and 46 patients had been treated initially by surgery. The results of surgery were generally good. However, in the group of "simple wedge excision" and in patients who had had radiotherapy as the primary treatment there was a higher incidence of recurrences. In the former group the recurrences were considered to be due to a too narrow angle of excision. We recommend surgery as the primary method of treatment because of the availability of histologically accurate tumour margin assessment, the short rehabilitation period and the good functional results achieved.
