The main part of the OCF site contains a wealth of information, including the National Comprehensive Cancer Network's annual guidelines for head and neck cancer treatment. These were developed by the NCCN, an alliance of 21 leading cancer centers in the U.S., and represent the latest thinking in the U.S. on cancer treatment. The guidelines cover many different types of oral cancers, so make sure you are looking at the right page (table of contents is on p. 3 of the guidelines).
