Abstract

Purpose
To report a case of combination therapy with interferon β1b (IFN-β1b) and mitomycin-C (MMC) for recurrent ocular surface squamous neoplasia (OSSN).
Case summary
A 72-year-old female presented with a white mass at the medial conjunctiva of the right eye. A gelatinous, nodular white lesion was observed near the medial limbus of the right eye. On histological examination, it was diagnosed as squamous cell carcinoma in situ. A white nodule was found at the resection site 1 year after the resection. IFN-β1b (1 mIU/mL) and 0.02% MMC were administered daily with a diagnosis of recurrent OSSN. IFN-β1b was instilled four times a day for 1 month, while MMC was instilled four times a day for 4 weeks. After 1 month of the combination treatment, the lesion disappeared. MMC was stopped, while IFN-β1b was reduced to twice daily instillation, maintained for 1 month, and then stopped. On examination 12 months after discontinuation of the combination treatment, there were no recurrences or drug-related complications.
Conclusions
Combination therapy with IFN-β1b and MMC for recurrent OSSN after surgical resection was relatively safe with no major complications.
