Introduction
Malignancies of the salivary glands are uncommon and comprise 3-4% of all head and neck cancers (1, 2). In the UK, the incidence was measured as 8-14 salivary gland cancers per million population (3). The World Health Organisation has defined 22 subtypes, each with different clinical characteristics(4). The low incidence and heterogeneity limit prospective study, and the sparsity of level I and II evidence makes it difficult to determine prognostic factors, optimise treatment, or assess long-term clinical outcome. The present study was carried out to evaluate clinicopathological determinants of oncological outcome in patients with malignant salivary gland tumours managed by curative intent with surgery.
