Lymph Node Status Cannot Be Ignored in Survival Analysis of Laryngeal Cancer

Arch Otolaryngol Head Neck Surg. 2008;134(7):786. doi:10.1001/archotol.134.7.786-a

The article by Chen and Halpern1 presents a good way of assessing the actual outcome of laryngeal cancer in a population following treatment modifications adopted based on level I evidence from clinical trials. The study actually looked at the outcome in a large sample of patients with laryngeal cancer over a long follow-up period. However, we have 2 reservations regardng the way the analysis was performed and the conclusions that were drawn from the analysis.
