PURPOSE: To evaluate the efficacy, recurrence rate, and long-term complications of topical mitomycin C (MMC) 0.02% for conjunctival-corneal intraepithelial neoplasia (CCIN). METHODS: A prospective, nonrandomized, noncontrolled study was conducted of patients with primary or recurrent CCIN treated with topical MMC 0.02%, four times per day, for 28 consecutive days. The main outcome measures were complete resolution of the neoplasia by slit-lamp examination and cytology 1 month after treatment, tumor recurrence, and long-term complications. RESULTS: Between June 1999 and September 2005, 23 patients were included. Eighteen had primary CCIN (group 1) and 5 had recurrent CCIN (group 2). The mean follow-up was 46 months in group 1 and 54 months in group 2. All patients were treated with MMC 0.02% for 28 consecutive days. Complete resolution of the lesion was achieved in all patients after 1 month of treatment. Recurrence occurred in 1 patient (4.3%) after 24 months of treatment. Four patients developed corneal erosion (17.4%), 2 of them with primary CCIN and 2 with recurrent CCIN. Corneal erosion occurred 4 to 24 months after treatment and was treated successfully. The probability for corneal erosions by the log-rank test was equal for both groups (p = 0.1705). CONCLUSIONS: The use of topical MMC 0.02% for 28 consecutive days to treat primary or recurrent CCIN was effective and showed a low recurrence rate. Corneal erosion occurred in 17.4% of cases and can occur as late as 24 months after treatment.
