The AJCC Cancer Staging Manual, now in its eighth edition, has traditionally been delivered as a book. The information in the Manual is complex and accessing it in a physical text was time-consuming. In addition, clinicians needed the ability to annotate their patient with information found in the Staging Manual. Integrating this complex information into health information systems was the answer, however, until now the developers of these systems had to manually convert the information into digital formats, organize it, and import it into their systems. This manual process was time-consuming and potentially error-prone.
