Lymph Node Yield as Quality Metric for Clinically N0 Oral Cancer

To the Editor In their research letter, Tsai et al evaluated lymph node yield in a cohort of patients with clinically N0 oral cavity cancer from the National Cancer Database (NCDB). They found an association of lymph node yield with survival. With a median node count of 23, they used neck dissections with 24 or more nodes as a variable in a multivariable analysis and found 24 or more nodes to be associated with improved survival.
