The american joint committee's proposed method of stage classification and end-result reporting applied to 1,320 pharynx cancers

This is the authors' abstract. We don't add key points for this paper.

A method of stage classification and endresult reporting of cancer is necessary for meaningful analysis of cancer control information. A staging system must be based upon information equally available regardless of the form of therapy used. With cancers of most sites this requires that the stage classification be a clinical one, that is, based on information available to physician, radiologist, and surgeon alike.
