From the reviews of the seventh edition: "The seventh edition of the AJCC Cancer Staging Manual is the most recent standard description of the anatomical presence and virulence of cancer. ... an obvious necessity for all cancer registries and members of clinical trials groups as well for cancer surgeons and medical and radiation oncologists. Readers involved in quality assurance can find it useful as well. Actuaries who determine insurability and rates will require this to guide their calculations. ... As a reference of cancer disease organization, it is the standard." (James R. Egner, Journal of the American Medical Association, Vol. 304 (15), October, 2010)
