I read with considerable interest the article titled “Laser Surgery for Early Glottic Cancer: Impact of Margin Status on Local Control and Organ Preservation” by Ansarin et al,1 which aimed to investigate the impact of margin status on local control and organ preservation in laser surgery for early glottic cancer. I would like to compliment the authors on their work, but I feel that some of the conclusions that they reached were not appropriately supported or explained by the statistical results.
