Staging system by sites. Problems and refinements

The authors believe that the present TNM system, while fallible, is founded on sound principles and represents the combined work and experience of many physicians who have spent many years treating cancer of the head and neck. Its shortcomings are as much a reflection of the complexity of the disease itself as a condemnation of the staging system. If all clinicians discipline themselves to meticulously apply the philosophy and guidelines of the present classification, useful data will have been gathered over that 10-year period. Only then can the Committee take a long and thoughtful look and evaluate the discrepancies of the present system and make intelligent changes where necessary. One must recognize the need to periodically revise such a system that has so many complexities and variables.
