Mitomycin-C as adjunctive treatment of Ocular Surface Squamous Neoplasia

Abstract

The aim of this study is to report the efficacy of topical Mitomycin-C (MMC) as adjunctive treatment following primary excision of ocular surface squamous neoplasia (OSSN).After detailed evaluation, 25 eyes in 25 patients with localized primary OSSN were selected in a prospective, interventional study and subjected to primary excision followed by the application of topical 0.04% MMC as an adjunct and thereafter followed up over a 24 month period for signs of any tumor recurrence. The 25 patients selected with primary OSSN had a mean age of 64(SD 13) with a range of 47-87 years. They underwent surgical excision followed by 3 cycles of freshly prepared 0.04% MMC with 2 weeks on and 2 weeks off for 12weeks.All patients were followed up thereafter at 1 week, 2 weeks, monthly for 6 months and every 3 months for the next 24 months. No tumor recurrence was observed in any of the cases.Topical MMC has a definite role in preventing tumor recurrence when used as adjunctive treatment following primary surgical excision of OSSN.
