Core Tip
Core Tip: The outbreak of coronavirus disease 2019 (COVID-19) has evoked concern worldwide. The rapid spread of the disease during the first and the second waves caused severe respiratory illness. Individuals are facing a suppressed immune response. An impaired immune response has made patients with head and neck cancer highly susceptible to the viral infection. The two potential receptors of severe acute respiratory syndrome coronavirus 2, angiotensin receptors and extracellular matrix metalloproteinase inducer, have contrasting effects on cancer progression. Thus, the molecular mechanisms and the biological behavior of oral squamous cell carcinoma show varying effects in the background of COVID-19.
