Radiotherapy versus open surgery versus endolaryngeal surgery (with or without laser) for early laryngeal squamous cell cancer.

Background: This is an update of a Cochrane review first published in The Cochrane Library in Issue 2, 2002 and previously updated in 2004, 2007 and 2010.Radiotherapy, open surgery and endolaryngeal excision (with or without laser) are all accepted modalities of treatment for early-stage glottic cancer. Case series suggest that they confer a similar survival advantage, however radiotherapy and endolaryngeal surgery offer the advantage of voice preservation.
