A retrospective review of the experience of a single surgeon over a 20-year period is presented. Fifteen patients with primary adenoid cystic carcinoma of the major (6) or minor (9) salivary glands underwent combined treatment with wide local excision and radical postoperative radiotherapy. The actuarial survival is 100% at 5 years and 62% at 10 and 15 years. The disease-specific survival is 100% at 5 years and 86% at 10 and 15 years. There were no loco-regional recurrences. Wide local excision and radical postoperative radiotherapy seems to be an effective treatment for adenoid cystic carcinoma of the salivary glands.
