Determinants and Patterns of Survival in Adenoid Cystic Carcinoma of the Head and Neck, Including an Analysis of Adjuvant Radiation Therapy

Abstract

Cause-specific survival continues to decline up to 30 years after diagnosis in ACC of the head and neck. In the interval between 10 and 30 years after diagnosis, patients are nearly as likely to die of ACC as from all competing causes combined. Certain clinicopathological factors are associated with decreased survival. There is no evidence of increased survival in patients receiving adjuvant RT.
