In general, a lacrimal gland tumor is rare. About half of lacrimal gland tumors are benign, and half are malignant. Malignant epithelial tumors of the lacrimal gland account for 2% of all orbital (eye socket) tumors. AdCC is the most frequent epithelial orbital cancer, accounting for approximately 50% of malignant lacrimal gland tumors and 25% of all lacrimal gland tumors.
Survival rates depend on several factors, including the type and subtype of lacrimal gland tumor. The five-year survival rate is the percentage of people who survive at least five years after the cancer is detected, excluding those who die from other diseases. The five-year survival rate of people with AdCC is estimated to be 50%, while the 15-year survival rate is estimated to be 25%.
Cancer survival statistics should be interpreted with caution. It is not possible to tell a person how long he or she will live with a lacrimal gland tumor. Because the survival statistics are measured in five-year intervals, they may not represent advances made in the treatment or diagnosis of a lacrimal gland tumor.
