Abstract

We present a retrospective multicentric study of 67 patients with adenoid cystic carcinomas of the intraoral minor salivary glands, who were diagnosed and treated between 1986 and 2004 in the Operative Units of Maxillofacial Surgery of the University of Parma and of the Bellaria Hospital in Bologna. There were 28 males and 39 females with a mean age of 54.5 years (range 28-84 years). The palate was the most common site of involvement, with 71.6% of cases. All the patients were treated with surgery as the primary modality. Neck dissection was performed in 9% of the patients, and more than half (59.7%) were treated with adjuvant radiation therapy. All surviving patients had a minimum of 2 years follow-up, with a range of 2-20 years (median: 12 years). Of the 67 patients examined in this study, 19 were dead at the end of the follow-up, 16 of them due to tumor disease. Distant or loco-regional recurrence was documented in 29 of the 67 patients (43.3%). Disease-free intervals ranged from 1 month to 12 years. Twenty-two percent of patients had loco-regional failure, whereas 29.8% had distant metastases. The disease specific survival rates were 76.1% at 5 years and 74% at 10 and 15 years.The actuarial loco-regional control rates at 5-, 10- and 15-years were 79.7%, 74.8% and 70%, respectively. The actuarial freedom from distant relapse was 76.5% at 5 years, 64.9% at 10 years and 61.1% at 15 years. Stage T, cervical lymph node metastasis and surgical margin status proved to make a statistically significant contribution when describing the outcome.
