Spots Global Cancer Trial Database for Topical Interferon Alfa 2b and Mitomycin C in Conjunctival-Corneal Intraepithelial Neoplasia

Study Description

Brief Summary: The purpose of this study is to evaluate the therapeutic efficacy of interferon alfa 2b and topical mitomycin C in patients with diagnosis of conjunctival-corneal intraepithelial neoplasia.

Detailed Description: The corneal and conjunctival intraepithelial neoplasia is the most common malignant tumor of the ocular surface.

Patients will be assigned to treatment with MMC or INFα2b Periodic clinical evaluations and photos will be made. Time of resolution, resistance and adverse effects will be determined. Patients treated with mitomycin will be handled by cycles until resolution of the lesion, which according to previous studies is expected between 3 and 6 cycles (between half months and 3 months).
