title: Does TANIS (T And N Integer Score) help predict survival?
abstract: OBJECTIVE
  This study was conducted to validate the TANIS model as a predictor of survival.
  
  
  METHODS
  Using Cox Proportional Hazards model, we examined the subgroups of the TANIS score levels to see if they were homogeneous on survival.
  
  
  METHODS
  The Departments of Otolaryngology and Oncology and the Radiation Oncology Research Unit at Queen's University in Kingston, Ontario.
  
  
  METHODS
  Five hundred and ninety-four patients with cancer of the head and neck classified by TNM and TANIS were analyzed for the outcome dead of disease using estimates of relative risk.
  
  
  CONCLUSIONS
  The stages of TNM and the levels of TANIS contain subgroups of patients with different survival rates.
