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.
