Takeaway

  • An increased diagnosis-to-treatment interval (DTI) is associated with reduced survival of patients with oral squamous cell carcinoma (OSCC).

Why this matters

  • Treatment delays may help explain why OSCC outcomes are not improving in Taiwan.

Key results

  • DTI 20 d was associated with reduced 5-y OS (HR, 1.07; P=.007 for 21-45 d; HR, 1.25; P<.001 for 46-90 d; HR, 1.28; P<.001 for ≥91 d).
  • DTI 30 d was also associated with reduced 5-y OS (HR, 1.10; P=.004 for 31-60 d; HR, 1.26; P=.002 for 61-90 d, HR, 1.26; P<.001 for ≥91 d).
