The impact of COVID-19 on head and neck cancer diagnosis and disease extent.

Background: Due to COVID-19, diagnostic delays and a surge of advanced head and neck cancer (HNC) is anticipated. We hereby evaluate patient and tumor characteristics before and during the early COVID-19 period.

Methods: Retrospective review of patients with HNC presented at a multidisciplinary tumor conference from May 14, 2020 to June 18, 2020 was performed and compared to a similar 6-week period a year before. Demographics, time to diagnosis, and tumor characteristics were analyzed.

Results: There was a 25% reduction in newly diagnosed malignancies. Groups were similar in baseline characteristics, duration of symptoms, and time to diagnosis. However, median primary tumor size was significantly larger (p = 0.042) and T stage more advanced for mucosal subsites (p = 0.025) in the COVID-19 group.

Conclusion: Our findings suggest increased tumor burden in patients with HNC presenting during the pandemic, despite a similar time to diagnosis. This may become more pronounced as the pandemic duration is extended.
