The American Joint Committee on Cancer (AJCC) published the 8th edition of its staging manual in 2016. This new manual applies to solid tumors diagnosed after January 1, 2018. Guidelines for hematologic and brain tumors have separate staging guidelines. AJCC continues to support cancer care with its work and commitment to improving patient care.

Cancer staging is vital for the appropriate management of a patient’s case. Incorrect staging may affect the appropriate treatment and reduce the patient’s survival. Pathologic staging requires expert knowledge of the disease. Pathologists must distinguish between single cancer cells and healthy cells. Misstaging can occur when a pathologist is relying solely on visual discretion. Another type of staging is random sampling, which involves cherry-picked lymph nodes in the hope of detecting cancer cells.
Staging a patient based on his or her tumor size and location is a vital part of the process. By analyzing the tumor size and location, a doctor can determine whether a patient is likely to develop cancer or not. A patient’s stage is an important part of treatment decisions, and cancer staging in the AJCC guidelines helps doctors plan the best treatment for the patient’s condition. For example, breast cancer staging is based on the TNM staging system, but may also use I-IV stages.
The 8th edition of the TNM classification uses nonanatomic prognostic factors to determine the outcome of a patient. These nonanatomic factors are known to affect a patient’s prognosis and are supported by sufficient evidence for incorporation into staging. Similarly, HPV-positive oropharynx cancers are more radiosensitive and less likely to develop alterations in the genetic makeup. This makes them more responsive to chemotherapy, while younger patients with fewer co-morbidities have better performance status.
While TNM classification has been widely used to classify cancers, it has generated a great deal of uncertainty and misunderstanding. As such, the AJCC recently updated the staging guidelines and the eighth edition of the Cancer Staging Manual. Since the AJCC has restructured their processes and put the staging data on an application programming interface (API), the ninth edition will be released chapter by chapter. This edition will be updated with the inclusion of cervical cancer staging.
The TNM classification has become the standard for defining the different stages of cancer and has become synonymous with prognosis. The TNM classification is a widely-used staging system, which emphasizes the anatomical extent of the disease and its easy application. Its purpose and definition were reviewed and agreed upon. The GCCS has affirmed the importance of cancer staging and has agreed to work toward achieving consensus on the terminology used for the process.
Achieving precision in cancer staging has become increasingly important. Several new, highly sensitive methods of cancer staging are currently under development. One such method, RT-PCR, is a technique for identifying the presence of GCC only in the luminal portion of the intestinal epithelium. This molecular screening technique is expected to reduce the underestimation of disease stage. Further development in this field will lead to more accurate diagnosis and better treatment options.
