Squamous cell carcinoma of the lip: a retrospective review of the Peter MacCallum Cancer Institute experience 1979-88.
BACKGROUND
Squamous cell carcinoma (SCC) of the lower lip is a common malignancy in Australia. Surgical excision and/or radiotherapy are used in treatment, and are regarded as equally effective.


METHODS
A retrospective review of 323 patients treated at the Peter MacCallum Cancer Institute with either surgical excision and/or radiotherapy, evaluated disease recurrence, cause-specific mortality, and the incidence of metachronous lesions.


RESULTS
Recurrence-free survival at 10 years was estimated to be 92.5%, and cause-specific survival at 10 years was estimated to be 98.0%. Equivalent rates of local control were obtained with surgery and radiotherapy. Recurrence was related to tumour stage and differentiation. A high incidence of metachronous lesions was noted, 25 patients had a lesion prior to presentation and 33 patients developed second lip lesions during the study period.


CONCLUSIONS
Squamous cell carcinoma of the lower lip is well treated with surgery or radiotherapy. The preferred treatment for most patients with SCC of the lower lip in the Australian population is surgical excision. This study has shown a significant incidence of metachronous lip neoplasia, except in those patients whose whole lip had been resurfaced.
