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.
