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.

Significantly expanded and developed by international disease site expert panels, the Eighth Edition* AJCC Cancer Staging System brings together all the currently available knowledge on the staging of cancer at various anatomic sites. Evidence-based TNM staging is supplemented, as appropriate, by selected molecular markers and newly acquired insights into the molecular underpinnings of cancer.

*AJCC has moved from Editions to Versions
The American Joint Committee on Cancer (AJCC) made an important change to how it updates and releases Cancer Staging content. The AJCC shifted from a Cancer Staging Manual to a Cancer Staging System and moved away from Editions to Versions. Version 9 went into effect on January 1st, 2021.

The AJCC Cancer Staging System remains the gold standard reference for oncologists, surgeons, pathologists, radiologists, cancer registrars, and medical professionals worldwide to ensure that all those caring for cancer patients are fully versed in the language of cancer staging.

"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.
