Abstract

Abstract: Survival rates for oral squamous cell carcinoma (OSCC) has remained stagnant in recent years and improving surgical mortality could be an avenue to enhance outcomes. This systematic review aims to identify the causes of mortalities, determine both the modifiable and non-modifiable factors involved and target a reduction in postoperative 30-day mortality. In May 2019, a comprehensive search of key databases including PubMed, EMBASE, Cochrane Library was conducted. Blinded selection by two researchers identified papers that included participants who received oral squamous cell carcinoma resection and suffered an in-hospital or 30-day mortality. Selection identified two relevant papers that meet the inclusion criteria. One study had one death in its population sample but only had the cause of death described. Another study had an overall surgical mortality rate of 1% in a population of 21, 681. Patients with multiple factors had the highest mortality rates; 4.6% in patients >85 years old and have a T4 diagnosis, 3.9% in patients with a Comorbidity Index ≥1 and a T4 diagnosis. These studies did not determine relationships between factors and causes of death. There are significant knowledge gaps in the literature, that can be addressed through further population analysis studies.
