Phase III randomised controlled trial Comparing Alternative Regimens for Escalating treatment of intermediate and high-risk oropharyngeal cancer



Summary and Eligibility: 
The CompARE study has been set up to investigate which treatment is most effective for patients who have higher-risk oropharyngeal cancer. The purpose of this study is to consider using additional treatments in conjunction with standard chemoradiotherapy to increase cure rates of higher-risk oropharyngeal cancer. This will  be done  by  adding  surgery  or  more  chemotherapy or higher  dose radiotherapy  to  the  standard chemoradiotherapy

If eligible for the study, patients will be randomly allocated to one of four treatment options:

  1. Standard chemoradiotherapy
  2. Chemotherapy plus higher dose radiotherapy
  3. Surgery plus chemoradiotherapy
  4. Immunotherapy plus chemoradiotherapy
