Who invented tnm staging

Anderson, MD — ; and subsequently by Oliver H. Under Dr. In keeping with the concept that the fledgling AJC should be a coalition of organizations that have cancer management as their primary goals, the initial sponsoring organizations of this seminal organization were the ACS, the ACR, the College of American Pathologists, the American College of Physicians, the American Cancer Society, and the National Cancer Institute.

As Dr. These task forces or expert panels were assigned to review available outcomes data culled from existing rudimentary hospital registries and literature reports. AJCC expert panels and editorial boards continue to use this nascent approach today. The National Cancer Database NCDB , created in the late s, is a proven resource for more modern approaches to updating the TNM system and inclusion of newer biological and molecular markers in cancer staging.

Throughout the ensuing decades, both the UICC and the AJCC have been partners in promoting and educating the international cancer health care community regarding the taxonomy of cancer staging and the importance of using both clinical and pathological staging to assess cancer outcomes.

Over the last 60 years, the original concepts recognized by the founders of the AJC have metamorphosed into the principles of the AJCC that embrace not only the importance of anatomic staging, but have highlighted the critical significance of prognostic and predictive factors into the modern concepts of cancer treatment. These dedicated professionals, especially registrars working in CoC-accredited institutions, have diligently collected, abstracted, and transmitted data on cancer patients to the NCDB, allowing for the information gleaned to be used in all elements of AJCC cancer staging and patient treatment.

As the AJCC begins its seventh decade of work, it is strengthened by the contributions of liaison members from other cancer-related organizations see sidebar. The opportunities to transform cancer staging from a purely anatomic basis to personalized cancer care are both daunting and exhilarating.

The inclusion of artificial neural networks that lead to robust risk-assessment tools in cancer care, and technical support systems that can translate the complexities of modern staging into understandable and useful instruments for both patients and clinicians alike, are also important agenda items for the AJCC.

Each individual aspect of TNM is termed as a category: T category describes the primary tumour site and size N category describes the regional lymph node involvement M category describes the presence or otherwise of distant metastatic spread.
