The stage of laryngeal cancer before and after the COVID-19 pandemic: A retrospective study

The primary objective of this study is to evaluate whether COVID-19 pandemic disruptions had influenced the greater advance of LC according to the TNM classification. We suspected that one year after the pandemic, the number of more patients with a more advanced cancer stage was visible than before the pandemic. Furthermore, we compared the type of surgery, complications and concordance of clinical TNM (cTMN) and pathological (pTNM) evaluation of LC before and after the pandemic.
