Purposes: To evaluate the efficacy of topical 5-fluorouracil (5-FU) in treating conjunctival and corneal epithelial neoplasia.
Methods: Three patients underwent surgical excision of bulky disease followed by topical 1% 5-FU in artificial tear base for 2 to 3 weeks or until epithelial separation occurred. An additional three patients underwent treatment with topical 1% 5-FU alone.
Results: Minimum follow-up was 6 months. In one patient with conjunctival in situ carcinoma and no detectable normal conjunctiva, who had normal findings on conjunctival histologic examination after application of topical 5-FU, a focus of invasive disease requiring orbital exenteration. One patient had a favorable response to 5-FU therapy but required a repeat excision for control of bulky disease. Four patients have remained disease-free for 10, 13, 18, and 30 months after topical 5-FU therapy.
Conclusion: With its potential selective toxicity on dysplastic epithelium, topical 5-FU shows promise as an adjunctive treatment for managing conjunctival and corneal epithelial neoplasia.
