The AJCC Cancer Staging System is the gold standard to help the cancer patient management team determine the correct stage for patients, allowing for the most appropriate care plan.

The AJCC Cancer Staging System is used by physicians and health care professionals throughout the world to facilitate the uniform description and reporting of neoplastic diseases. Proper classification and staging of cancer are essential for the physician to assign proper treatment, evaluate results of management and clinical trials, and serve as the standard for local, regional, and international reporting on cancer incidence and outcome.

The new AJCC Protocol Version 9 content is presented in a streamlined, easy-to-use format including synoptic staging report format, tables, explanatory notes, and illustrations. All disease sites in the 8th Edition Cancer Staging Manual remain current until replaced with Version 9.

"Overall, this edition is a welcome update, incorporating new advances in cancer knowledge to more accurately reflect modern cancer care. Importantly, it has taken our knowledge of prognostic factors other than anatomy and blended them into the well-known TNM staging system. It will be a valuable tool for students, researchers, and clinicians as they care for cancer patients."

-- Emily Albright, MD - (University of Iowa Hospitals and Clinics) Doody's Review


This is a valuable reference for students, physicians, scientists, and cancer registrars. With clear descriptions and definitions of terminology, it can be used by experienced practitioners as well as those new to cancer staging.
