Times to Diagnosis, Staging, and Treatment of Head and Neck Cancer Before and During COVID-19.

This study found that time to diagnosis for head and neck cancers was delayed during a COVID-19 period compared to a pre-COVID-19 period. However, there was no evidence of delays in time to staging and time to treatment during the COVID-19 period. Our results prompt further investigations into the factors contributing to diagnostic delays but provide reassurance that despite COVID-19, patients were receiving timely staging and treatment for head and neck cancers.
