Basal cell carcinoma of the lip treated with radiotherapy.

Basal cell carcinoma (BCC) of the lip is uncommon relative to other cutaneous sites for BCC, such as the central face or scalp. A female predisposition and predilection for the upper lip have been previously documented. A retrospective analysis of patients treated for BCC of the lip was undertaken within the department of Radiation Oncology, Westmead Hospital, Sydney. Twenty patients were identified; 12 women and 8 men. The majority (15/20) had T1 lesions of the upper lip (17/20). Eleven patients were referred for radiotherapy alone and nine for adjuvant radiotherapy following either incomplete excision or local recurrence. With a mean follow up of 36 months no patient has recurred following either definitive or adjuvant radiotherapy. Despite the majority of BCCs of the lip being amenable to surgery fractionated external beam radiotherapy remains an option especially when functional and/or cosmetic concerns are an issue. We present the findings from this small case series and use our findings to illustrate the role of radiotherapy in treating BCC of the lip.
