Use of 5% imiquimod cream in the treatment of facial basal cell carcinoma: a 3-year retrospective follow-up study

There has been considerable research into the safety and efficacy of topical 5% imiquimod cream for the treatment of skin cancers in recent years, in particular superficial and nodular basal cell carcinomas. However, there are limited long-term follow-up studies. This retrospective study aims to determine the efficacy of 5% imiquimod cream in the treatment of facial basal cell carcinomas over 3 years. Medical records of 12 patients treated with 5% imiquimod cream at a private dermatology practice during 2001 and 2002 were retrospectively reviewed. Target tumours included superficial and nodular basal cell carcinomas, giving a total lesion number of 19. Patients were commenced on a once daily treatment regimen for up to 9 weeks, and given rest periods as required according to the severity of application site reactions. We found that 5% imiquimod cream is an effective treatment option for superficial and nodular basal cell carcinomas, giving a clearance rate of 89.5% at an average of 39 months of follow up.
