Introduction: Head and neck cancer is a common disease worldwide. The prevalence varies among different regions of the world and mirrors the occurrence of risk factors for head and neck cancers. The chronic exposure of risk factors of head and neck cancer to upper aerodigestive tract mucosa leads to cancer or less commonly to field cancerisation, a process of premalignant dysplastic lesions that are at high risk of progression to cancer. Aims: To evaluate the influence of vital pre-treatment variables employed in evaluation and treatment of head and neck carcinomas in predicting prognosis. To assess the feasibility of stratifying head and neck cancer patients into risk groups based on significant variables affecting survival endpoints.
