It is generally stratified into high, intermediate, and low risk prognostic groups on the basis of HPV (human papillomavirus) status and smoking history (Ang risk stratification). Frailty has been shown to have a negative survival effect in head and neck cancer. The effect of frailty on survival in OPSCC is unknown. The aim of this study was to explore overall survival (OS) and disease\u2010specific survival (DSS) in OPSCC based on the modified 5\u2010item frailty index (mFI\u20105).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This was a retrospective cohort study of patients diagnosed with OPSCC in the West of Scotland.

The median OS was shortened in both the 'Moderately Frail' (39\u2009months) and 'Severely Frail' groups (11\u2009months) compared with the 'Not Frail' group (82\u2009months) (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001).
