Sebaceous gland carcinoma of the head and neck: the Princess Margaret Hospital experience.

Background. The purpose of this study was to identify prognostic factors predicting outcomes in sebaceous gland carcinomas. Methods. We conducted a retrospective medical chart review of patients with sebaceous carcinomas of periorbital (n = 33) and extraorbital sites (n = 13). Results. Patients with periorbital tumors had higher recurrence rates than did patients with extraorbital tumors (64% vs 23%; p = .032). Patients who were older than 60 years (p = .035) and had lower eyelid tumors (p < .0001) had a lower disease-free survival rate than did patients with upper eyelid tumors. Patients with sebaceous carcinomas had a high rate (60%) of occult lymph node metastases. Conclusion. Periorbital tumors are associated with poorer outcomes than are extraorbital tumors. Lower eyelid carcinomas have the worst prognosis and should be treated more aggressively. Our findings of a high incidence of occult neck disease and a high rate of regional recurrence in patients with sebaceous carcinomas support the consideration of prophylactic elective neck dissections for treating such patients.
