[Carcinoma of the lip: a retrospective study of 86 cases].
Carcinoma of the lip is a common lesion which is not always acknowledged as as a potentially lethal disease. The risk of cancer occurs most commonly among aging white men. The risk factors normally associated with lip cancer are rural residence and outdoor occupation. In addition, both actinic radiation and tobacco smoking have been considered casually related to lip cancer. The present study is based on a retrospective review of 86 patients (82 males, 4 females, mean age 65) affected by carcinoma of the lip, treated in Florence from 1970 to 1988. The most frequent site for carcinoma of the lip proved to be the lower lip (71 cases); other sites included the upper lip (7) and the commissure (8). The lip tumor was a squamous cell carcinoma in 82 patients and a basal cell carcinoma in the remaining four. Good prognosis was found for all those with relatively small lesions (T1-T2). On the contrary, the prognosis proved quite poor for those who exhibited tumor fixation to the mandible or erosion of the mandible (23.5%, 5 year survival). Primary radiotherapy may be used for the smaller lesions as cure rates proved equivalent to those achieved surgically although the authors found surgery is always preferable as a primary method of treatment. Surgical excision of the tumor is a relatively minor procedure with a minimum of morbidity as compared with radiation therapy which may lead to local tissue reaction and may disturb function. Surgical management is also recommended as it bears the advantage of being to give a histologically accurate tumor margin assessment. Moreover, with surgery, functional results are good.(ABSTRACT TRUNCATED AT 250 WORDS)
