Low socioeconomic status (SES) has been associated with worse survival outcomes in oral cavity cancer (OCC). However, this effect on acute post-operative complications has never been studied.


To study the effect of SES on length of hospital stay (LOHS) and acute postoperative complications in OCC.


Newly diagnosed OCC patients from 2010-2014 were identified from a prospectively collected database. Patient, clinical, and outcomes data were analyzed by income quartiles based on neighbourhood level Canada Census 2011 data.


172 patients were included. Low SES was associated with longer LOHS (p=0.003) and more acute complications (p=0.001). Multivariate regression analysis showed that low SES, smoking status, cT and cN Stage, higher CCI were more likely to be associated with LOHS (R2=0.102, p<0.003) and acute complication rates (R2=0.114, p<0.004).


Low SES patients have more advanced disease with increased comorbidities contributing to more acute post-operative complications and LOHS.

Learning Objectives

  1. To discuss the impact of socioeconomic status on post-operative complications and length of hospital stay in oral cavity cancer patients
  2. To understand specific patient factors that contribute to or are predictive of poor outcomes in the acute post-operative period
