Purpose: To study the long-term efficacy and safety of local application of imiquimod 5% and fluorouracil 1% creams in complex eyelid basal cell carcinomas (BCCs). Methods: A retrospective, non-comparative study in biopsy-proven, complex (involving canthi or >50% of eyelid length) eyelid BCC patients who were medically unfit for surgical procedures. All patients were medically treated with either of the creams using fixed-dose regimens for a minimum of 3 months. All received oral vitamin C 500 mg QID for 3 months as an adjunct for collagen healing. A minimum of “post-treatment” follow-up of 12 months was observed. Results: Of total 30 patients, imiquimod 5% and fluorouracil 1% were used in 16 and 14 patients, respectively. The mean age of our patients was 70.5 years. The co-morbidities included – severe coronary artery disease using blood-thinners ( n = 19), poorly controlled diabetes ( n = 12), poorly controlled hypertension ( n = 6), on nebulization ( n = 3), and tuberculosis with pulmonary fibrosis ( n = 2). Complete clinical tumor resolution was noted in 10 and 8 patients over 12 and 16.5 weeks, respectively, in imiquimod and fluorouracil groups. Periocular skin erythema, chemical conjunctivitis, and skin depigmentation were seen in all the patients of imiquimod group. On the other hand, the local side-effect profile in fluorouracil patients was limited. Conclusion: The medical treatment of complex eyelid BCC is a useful alternative to surgery in the elderly with significant co-morbidities. It provides a promising long-term relief with a tolerable side-effect profile. A prospective, randomized, double-blinded trial would provide stronger evidence for the efficacy of these drugs.
