Unlabelled: OBJECTIVE To examine survival differences in prognosis and survival between patients with HPV-positive and those with HPV-negative oropharyngeal squamous cell carcinoma (OPSCC).
Methods: Pubmed, Embase, Web of science and Medline databases were searched from their inception till June 2014. A random-effect meta-analysis was used to pool study estimates evaluating overall (all-cause mortality), disease-specific (death from OPSCC), disease-free (recurrence free), progression-free survival outcomes and local regional control rate in HPV-positive vs HPV-negative OPSCC.
