The most recent revision is the 7th edition, effective for cancers diagnosed on or after January 1, This editorial summarizes the background of the current revision and outlines the major issues revised. Most notable are the marked increase in the use of international datasets for more highly evidenced-based changes in staging, and the enhanced use of nonanatomic prognostic factors in defining the stage grouping. The future of cancer staging lies in the use of enhanced registry data standards to support personalization of cancer care through cancer outcome prediction models and nomograms. The extent of a cancer at time of diagnosis is a key factor used to define treatment and to assess the chance of successful treatment outcome.

Implementation of these new staging rules also will improve data collection, which will provide the basis for further refinements in TNM staging for these sites.

Future prognostic systems, such as the nomogram systems described by Kattan and colleagues, may allow further refinements in prediction tools, but will not obviate the need for careful assessment of anatomic extent of disease.

Gastrointestinal Oncology First Online: Goals of the Revised Gastric Cancer Staging System Despite declining incidence in the United States and many other western countries, gastric cancer continues to be a worldwide health problem, with more than , cases reported annually, far higher than pancreatic cancer with , cases.

Key features and changes to the recommendations to the TNM gastric cancer staging system for the 7th edition include the following: T4 is now defined as a tumor that invades the serosal visceral peritoneum or adjacent structures.

T3 tumors also include those extending into the gastrocolic or gastrohepatic ligaments, or into the greater or lesser omentum, without perforation of the visceral peritoneum covering these structures T4 Tumor invades serosa visceral peritoneum or adjacent structures T4a Tumor invades serosa visceral peritoneum T4b Tumor invades adjacent structures such as spleen, transverse colon, liver, diaphragm, pancreas, abdominal wall, adrenal gland, kidney, small intestine, and retroperitoneum.

The T1 category has been subdivided into T1a invasion of lamina propria or muscularis mucosae and T1b invasion of submucosa to facilitate data collection efforts.

AJCC Cancer Staging 7th Edition

Because gastric carcinoma, unlike colorectal carcinoma, may have associated lymph node metastases when tumor is still confined to the lamina propria, invasion of the lamina propria or muscularis mucosae is classified as T1a instead of carcinoma in situ Tis. This difference in tumor biology is attributed to the abundance of lymphatic channels in then gastric mucosa, in contrast to the colonic mucosa, in which lymphatic vessels are few and primarily located at the base of the mucosa.

NX Regional lymph node s cannot be assessed N0 No regional lymph node metastasis N1 Metastasis in 1 to 2 regional lymph nodes N2 Metastasis in 3 to 6 regional lymph nodes N3 Metastasis in 7 or more regional lymph nodes.

J Clin Oncol. In addition, the grouping schemas provide for assigning a stage group when the nonanatomic factors are not available. This is critical to assure worldwide applicability. These factors are also incorporated into the CS data collection system version 2 CSv2.

A number of disease taskforces identified the response of the cancer to systemic or radiation therapy as key prognostic information. These included breast cancer, rectal cancer, esophageal cancer, head and neck cancers, and others. A number of these sites include response to treatment as a prognostic factor for collection.

To address this need, the CS system will be further revised to include data fields for collection of information on the extent of T and N before and after neoadjuvant treatment. This enhancement of CS will be implemented in It is expected that this detailed exposition of the rules will reduce variation in interpretation of staging rules and result in higher-quality data.

In addition, in collaboration with the UICC, key rules have been clarified and revised. An important example is the rule related to the timeframe in which data may be obtained for clinical and pathologic staging in relation to date of diagnosis and initiation of treatment.

Assignment of cM0 does not require any imaging or other evaluation beyond history and physical examination. The appearance of the manual itself has been enhanced to make it more user-friendly. The manual uses enhanced type fonts plus color-coding for T, N, and M elements. We hope that this series of editorials in the Annals of Surgical Oncology will further assist clinicians in understanding staging, and the changes made in TNM.

However, publication of the 7th edition is just the next step. The 7th edition is also a springboard to the exciting future of personalized cancer care using data to more specifically define prognosis and the potential for benefit from specific therapies.

The AJCC will lead the charge to bring scientific advances to broad clinical use to provide these advantages to all cancer patients worldwide. All such efforts require the input of legions of people who deserve enormous credit for their efforts. Members of each taskforce are listed in the manual.

In addition, the AJCC owes a deep debt of gratitude to the staff at the AJCC, the registrars and scientists in surveillance organizations working on CSv2, and the many around the world who have contributed. His vision over the last three decades led to many of the strategic decisions that led the AJCC to its current position, from where it is poised for an exciting future.
