Ocular surface squamous neoplasia: insights from 67 cases at a Quebec tertiary center.

In total, 67 eyes from 66 patients with a median age at diagnosis of 71 years (range 43-92) were identified.

Of the patients, 67.2% (n = 45) were male, and 25.5% (n = 13/51) had a history of skin cancer.

Lesions most frequently presented on the bulbar conjunctiva (41%, n = 57), the limbus (25.9%, n = 36), and/or the cornea (13.7%, n = 18).

On Cox regression, recurrences were not associated with specific treatment approaches (all hazard ratio CIs crossing 1; P > 0.639) but were associated with positive margins (hazard ratio 3.892; P = 0.04).
