Topical mitomycin-C for pagetoid invasion of the conjunctiva by eyelid sebaceous gland carcinoma.
OBJECTIVE
To evaluate the efficacy of topical mitomycin-C for pagetoid invasion of the conjunctiva by sebaceous gland carcinoma.


METHODS
Prospective noncomparative consecutive interventional case series.


METHODS
All patients received topical 0.04% mitomycin-C four times daily for 1 week followed by 1 week off medication. The treatment cycles were repeated until resolution of the conjunctival malignancy was clinically evident.


METHODS
Four patients with histopathologically proven intraepithelial (pagetoid) invasion of the conjunctiva by sebaceous gland carcinoma were managed with this regimen.


RESULTS
The mean patient age was 78 years. Before treatment, the main tumor site included the upper eyelid in two cases and the lower eyelid in two cases. Previous resection of the tumor had been performed elsewhere in three cases over the prior 6 years. At the time of our examination, map biopsies confirmed pagetoid invasion involving 25% to 90% of the conjunctival surface, with bulbar, forniceal, and tarsal conjunctival involvement in all four cases and corneal extension in one case. There was no evidence of deep tumor within the conjunctival stroma or tarsus in any case. After treatment, medication intolerance and early discontinuation occurred in one patient, and continued tumor progression was documented. Of the remaining three patients, chemotherapy was used for a mean of four cycles with complete resolution of the pagetoid invasion, confirmed histopathologically in two cases, and without recurrence in all three cases over 12 months (mean) follow-up. The medication caused moderate temporary local irritation but no serious intraocular or extraocular complications.


CONCLUSIONS
Preliminary evidence suggests that topical mitomycin-C is effective treatment for pagetoid invasion of the conjunctiva by sebaceous gland carcinoma. Longer follow-up is necessary to assess the duration of tumor control.
